Resource Conservation and Recovery Act permit modifications and the functional equivalency demonstration: a case study
Hazardous waste operating permits issued under the Resource Conservation and Recovery Act (RCRA) often impose requirements that specific components and equipment be used. Consequently, changing these items, may first require that the owner/operator request a potentially time-consuming and costly permit modification. However, the owner/operator may demonstrate that a modification is not required because the planned changes are ``functionally equivalent.`` The Controlled-Air Incinerator at Los Alamos National Laboratory is scheduled for maintenance and improvements. The incinerator`s carbon adsorption unit/high efficiency particulate air filtration system, was redesigned to improve reliability and minimize maintenance. A study was performed to determine whether the redesigned unit would qualify as functionally equivalent to the original component. In performing this study, the following steps were taken: (a) the key performance factors were identified; (b) performance data describing the existing unit were obtained; (c) performance of both the existing and redesigned units was simulated; and (d) the performance data were compared to ascertain whether the components could qualify as functionally equivalent. In this case, the key performance data included gas residence time and distribution of flow over the activated carbon. Because both units were custom designed and fabricated, a simple comparison of manufacturers` specifications was impossible. Therefore, numerical simulation of each unit design was performed using the TEMPEST thermal-hydraulic computer code to model isothermal hydrodynamic performance under steady-state conditions. The results of residence time calculations from the model were coupled with flow proportion and sampled using a Monte Carlo-style simulation to derive distributions that describe the predicted residence times.

RCRA permit modifications and the functional equivalency demonstration: A case study
SciTech Connect
Hazardous waste operating permits issued under the Resource Conservation and Recovery Act (RCRA) often impose requirements, typically by reference to the original permit application, that specific components and equipment be used. Consequently, changing these items, even for the purpose of routine maintenance, may first require that the owner/operator request a potentially time-consuming and costly permit modification. However, the owner/operator may demonstrate that a modification is not required because the planned changes are functionally equivalent, as defined by RCRA, to the original specifications embodied by the permit. The Controlled-Air Incinerator at Los Alamos National Laboratory is scheduled for maintenance and improvements that involve replacement of components. The incinerator`s carbon adsorption unit/high efficiency particulate air filtration system, in particular, was redesigned to improve reliability and minimize maintenance. A study was performed to determine whether the redesigned unit would qualify as functionally equivalent to the original component. in performing this study, the following steps were taken: (a) the key performance factors were identified; (b) performance data describing the existing unit were obtained; (c) performance of both the existing and redesigned units was simulated; and (d) the performance data were compared to ascertain whether the components could qualify as functionally equivalent.

Light Water Reactor Sustainability Program Risk Informed Safety Margin Characterization (RISMC) Advanced Test Reactor Demonstration Case Study
Safety is central to the design, licensing, operation, and economics of Nuclear Power Plants (NPPs). Consequently, the ability to better characterize and quantify safety margin holds the key to improved decision making about LWR design, operation, and plant life extension. A systematic approach to characterization of safety margins and the subsequent margins management options represents a vital input to the licensee and regulatory analysis and decision making that will be involved. The purpose of the RISMC Pathway R&D is to support plant decisions for risk-informed margins management with the aim to improve economics, reliability, and sustain safety of current NPPs. Goals of the RISMC Pathway are twofold: (1) Develop and demonstrate a risk-assessment method coupled to safety margin quantification that can be used by NPP decision makers as part of their margin recovery strategies. (2) Create an advanced RISMC toolkit that enables more accurate representation of NPP safety margin. This report describes the RISMC methodology demonstration where the Advanced Test Reactor (ATR) was used as a test-bed for purposes of determining safety margins. As part of the demonstration, we describe how both the thermal-hydraulics and probabilistic safety calculations are integrated and used to quantify margin management strategies.

Stories of the Unheard: A Case Study of Five Mexican American Dropouts Labeled as Demonstrating Learning Disabilities
E-Print Network (OSTI)
This qualitative study examined the dropout crises from the perspectives of Mexican American dropouts labeled as learner disabled who were receiving special education services. Such study is imperative as this group increases both in school and in special education classes. There were two research questions that guided the study: 1. What are the perceptions of Mexican American dropouts who participated in a special education program regarding their educational experiences? 2. What were the factors that influenced these students decisions to drop out of school? From the participant interviews, historical academic documents, and rich-descriptive information gathered from the students voices, three themes were revealed as the primary reason for dropping out of school: non-responsive school culture, lack of supportive environment, and social factors. It was evident in the data collected that the school culture was unfavorable toward their learning and in meeting successful graduation requirements. Under non-responsive school culture, the following subthemes emerged as underlining factors to their dropping out: (a) low expectations, (b) non-caring for the student, (c) ineffective curriculum content, and (d) social issues at school. School-related factors such as the lack of a supportive environment revealed the following subthemes: (a) symptoms of school failure, (b) negative learning environment, and (c) culturally non-responsive instruction. Other attributing factors for dropping out of school included family structures and peer pressure. While each of the participants had unique experiences, each attributed non-responsive school culture, lack of supportive environment, and social context as major factors for dropping out of school. Therefore, the significance of this study lies in the potential to impact Mexican American student achievement in the reduction of dropouts.

NWCC Transmission Case Study III
OAK-B135 Transmission System Improvements for Wind Energy Development in the Upper Midwest and Great Plains: Opportunities and Obstacles. This case study set out to ascertain the validity of three assumptions from the perspectives of stakeholders involved in wind energy and transmission issues in the Upper Midwest and Great Plains. The assumptions, and the stakeholders' reactions to each, are summarized below: Assumption 1--Transmission system improvements would provide significant benefits to the electricity network and its customers. Respondents acknowledge the potential for overall system benefits in the form of reduced line losses, improved grid stability and reliability, and enhanced ability to conduct spot market transactions. They also agree that these benefits relate to specific regional needs. However, there is disagreement over the extent of other benefits such as efficiency gains and cost savings from reduced line losses. Further, environmental and community interest groups point out that none of these benefits are realized without significant financial, environmental and social costs. Assumption 2--The benefits of transmission improvements would be helpful, but not confined, to wind power. All respondents agree that wind energy could benefit from transmission system improvements. But they also acknowledge, reluctantly, in the case of environmental stakeholders, that the benefits of an improved transmission system cannot be limited to environmentally preferable forms of generation. Some environmental and community advocate respondents also feel that transmission system improvement projects can be avoided altogether through energy conservation and efficiency measures, and by substituting wind energy for fossil generation. Assumption 3--Transmission alliances among stakeholders within and external to the wind community can provide benefits in the public interest. The fractured, multi-jurisdictional governance of the regional transmission system, and the distrust and diversity of perspectives among affected stakeholders, may make the formation of multi-stakeholder alliances necessary to accomplishing transmission goals. If the wind industry and utilities want to partner with environmental and community advocate groups in supporting a transmission project, they may have to convince these groups that the project would result in a net environmental benefit. The project proponents would have to make the case that the benefits of the additional wind energy will at least offset the emissions of any additional fossil generation made possible by the transmission project, as well as offset the environmental impact of the transmission project itself.

Demonstration testing and evaluation of in situ soil heating. Treatability study work plan (Revision 2)
A Treatability Study planned for the demonstration of the in situ electromagnetic (EM) heating process to remove organic solvents is described in this Work Plan. The treatability study will be conducted by heating subsurface vadose-zone soils in an organic plume adjacent to the Classified Burial Ground K-1070-D located at K-25 Site, Oak Ridge. The test is scheduled to start during the fourth quarter of FY94 and will be completed during the first quarter of FY95. Over the last nine years, a number of Government agencies (EPA, Army, AF, and DOE) and industries sponsored further development and testing of the in situ heating and soil decontamination process for the remediation of soils containing hazardous organic contaminants. In this process the soil is heated in situ using electrical energy. The contaminants are removed from the soil due to enhanced vaporization, steam distillation and stripping. IITRI will demonstrate the EM Process for in situ soil decontamination at K-25 Site under the proposed treatability study. Most of the contaminants of concern are volatile organics which can be removed by heating the soil to a temperature range of 85{degrees} to 95{degrees}C. The efficiency of the treatment will be determined by comparing the concentration of contaminants in soil samples. Samples will be obtained before and after the demonstration for a measurement of the concentration of contaminants of concern. This document is a Treatability Study Work Plan for the demonstration program. The document contains a description of the proposed treatability study, background of the EM heating process, description of the field equipment, and demonstration test design.

High Penetration Photovoltaic Case Study Report
Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

NWCC Transmission Case Study Conclusions Summary
OAK-B135 The NWCC Transmission Case Studies Conclusions Summary In the spring of 1999, the Utility Wind Interest Group (UWIG), with the cooperation of the National Wind Coordinating Committee (NWCC), conducted a forum on transmission issues associated with the production of energy from wind. As a result of this forum, a number of issues were identified which, if successfully resolved, could help reduce barriers to the future expansion of wind power. The NWCC, being a multi-stakeholder group, was in an ideal position to conduct follow-up activities among a cross-section of the interested parties. The follow-up activities took the form of three case studies in the areas of interest identified by forum participants: (1) Transmission policy and pricing; (2) ''Virtual wheeling'' arrangements; and, (3) Transmission system improvements. The case studies provide an interesting snapshot in time dealing with a range of issues associated with scheduled or planned regulatory and restructuring proceedings related to energy transmission. The NWCC Transmission Subcommittee and the UWIG reviewed early drafts of the case studies in November 1999. The case studies were conducted through a questionnaire and interview process with interested parties. In writing each case study, NWCC staff attempted to identify all stakeholder groups with an interest in each topic and solicit their input. While all parties do not agree on every issue presented, a serious effort has been made to present all views in an unbiased fashion. At the end of each case study, relevant conclusions are drawn and recommendations for next steps are provided where appropriate.

A Case Study of Wide Diameter Casing for Geothermal Systems
Three wells have been drilled in the central resistivity area of a geothermal field in the Taupo Volcanic Zone, New Zealand. Using a well bore simulator, WELL SIM V3.0, reservoir conditions and well characteristics are evaluated to determine the increase in output by increasing production casing diameters from either 8-5/8 inches OD or 9-5/8 inches OD to 13-3/8 inches OD. Increases in well drilling costs are determined to provide a commentary on the economics. While open hole size is effectively doubled, well costs increase by 10% and, in this study, output increases by an average of 18%.

Demonstration testing and evaluation of in situ soil heating. Treatability study work plan, Revision 1
A Treatability Study planned for the demonstration of the in situ electromagnetic (EM) heating process to remove organic solvents is described in this Work Plan. The treatability study will be conducted by heating subsurface vadose-zone soils in an organic plume adjacent to the Classified Burial Ground K-1070-D located at K-25 Site, Oak Ridge. The test is scheduled to start during the fourth quarter of FY94 and will be completed during the first quarter of FY95. The EM heating process for soil decontamination is based on volumetric heating technologies developed during the `70s for the recovery of fuels from shale and tar sands by IIT Research Institute (IITRI) under a co-operative program with the US Department of Energy (DOE). Additional modifications of the technology developed during the mid `80s are currently used for the production of heavy oil and waste treatment. Over the last nine years, a number of Government agencies (EPA, Army, AF, and DOE) and industries sponsored further development and testing of the in situ heating and soil decontamination process for the remediation of soils containing hazardous organic contaminants. In this process the soil is heated in situ using electrical energy. The contaminants are removed from the soil due to enhanced vaporization, steam distillation and stripping. IITRI will demonstrate the EM Process for in situ soil decontamination at K-25 Site under the proposed treatability study. Most of the contaminants of concern are volatile organics which can be removed by heating the soil to a temperature range of 85 to 95 C. The efficiency of the treatment will be determined by comparing the concentration of contaminants in soil samples. Samples will be obtained before and after the demonstration for a measurement of the concentration of contaminants of concern.

A study of hazardous air pollutants at the Tidd PFBC Demonstration Plant
The US Department of Energy (DOE) Clean Coal Technology (CCD Program is a joint effort between government and industry to develop a new generation of coal utilization processes. In 1986, the Ohio Power Company, a subsidiary of American Electric Power (AEP), was awarded cofunding through the CCT program for the Tidd Pressure Fluidized Bed Combustor (PFBC) Demonstration Plant located in Brilliant, Ohio. The Tidd PFBC unit began operation in 1990 and was later selected as a test site for an advanced particle filtration (APF) system designed for hot gas particulate removal. The APF system was sponsored by the DOE Morgantown Energy Technology Center (METC) through their Hot Gas Cleanup Research and Development Program. A complementary goal of the DOE CCT and METC R&D programs has always been to demonstrate the environmental acceptability of these emerging technologies. The Clean Air Act Amendments of 1990 (CAAA) have focused that commitment toward evaluating the fate of hazardous air pollutants (HAPs) associated with advanced coal-based and hot gas cleanup technologies. Radian Corporation was contacted by AEP to perform this assessment of HAPs at the Tidd PFBC demonstration plant. The objective of this study is to assess the major input, process, and emission streams at Plant Tidd for the HAPs identified in Title III of the CAAA. Four flue gas stream locations were tested: ESP inlet, ESP outlet, APF inlet, and APF outlet. Other process streams sampled were raw coal, coal paste, sorbent, bed ash, cyclone ash, individual ESP hopper ash, APF ash, and service water. Samples were analyzed for trace elements, minor and major elements, anions, volatile organic compounds, dioxin/furan compounds, ammonia, cyanide, formaldehyde, and semivolatile organic compounds. The particle size distribution in the ESP inlet and outlet gas streams and collected ash from individual ESP hoppers was also determined.

Computer demonstration of an interactive modeling system for the study of global change and biogeochemistry
There is a need for visually oriented materials to aid in the study of global ecological science. Analysis of the carbon cycle is key to understanding Potential climate change. We have used satellite imagery along with global climate and soil texture data sets to simulate seasonal patterns in net carbon fixation and soil CO[sub 2] production. An interactive computer system is used to illustrate graphical results from various model scenarios of climate warming and land use change. These include global animations of monthly gridded CO[sub 2] exchange between the atmosphere and the terrestrial biosphere. This modeling demonstration highlights the importance of annual CO[sub 2] fluxes in tropical forests (40% of global totals) and the large carbon storage potential in boreal and arctic soils.

Demonstration of an advanced circulation fludized bed coal combustor phase 1: Cold model study. Final report
It was found that there was a strong dependence of the density profile on the secondary air injection location and that there was a pronounced solid separation from the conveying gas, due to the swirl motion. Furthermore, the swirl motion generated strong internal circulation patterns and higher slip velocities than in the case of nonswirl motion as in an ordinary circulating fluidized bed. Radial solids flux profiles were measured at different axial locations. The general radial profile in a swirling circulating fluidized bed indicated an increased downward flow of solids near the bed walls, and strong variations in radial profiles along the axial height. For swirl numbers less than 0.9, which is typical for swirling circulating fluidized beds, there is no significant increase in erosion due to swirl motion inside the bed. Pending further investigation of swirl motion with combustion, at least from our cold model studies, no disadvantages due to the introduction of swirl motion were discovered.

Baca geothermal demonstration project baseline ecosystem studies of cooling tower emission effects
Results of baseline studies for boron, arsenic, mercury, and fluorine in vegetation and soil near the Baca Geothermal Demonstration Power Plant are provided for the 1980 sampling season. Preliminary results of visual vegetation assessments and population density studies of soil invertebrate fauna are also provided. Foliage samples were collected for chemical analysis on a total of 17 plots on 5 transects. Two to five plant species were sampled at each plot. Samples were collected in June-July and September. Soil samples were collected at each plot during September. Visual vegetation inspections were conducted along each transect. Eighty-eight soil samples were collected for soil invertebrate studies. Boron, arsenic, mercury, and fluorine levels in vegetation were within normal range for natural vegetation and crops. Concentrations of soil arsenic and mercury were comparable to foliage concentrations. Boron concentrations were lower in soil than in foliage, whereas soil fluorine concentrations were considerably higher than foliage concentrations. With the exception of heavy insect infestations in June-July, no vegetation abnormalities were noted. Preliminary soil invertebrate analysis indicated an overall arthropod density of approximately 100,000/m/sup 2/ which appears within the normal range encountered in forest and meadow soil.

Bioremediation demonstration on Kwajalein Island: Site characterization and on-site biotreatability studies
An environmental study was conducted during February 1991 on Kwajalein Island, a US Army Kwajalein Atoll (USAKA) Base in the Republic of the Marshall Islands (RMI). This study was undertaken for the US Department of Energy (DOE) Hazardous Waste Remedial Actions Program (HAZWRAP) acting in behalf of USAKA. The purpose of the study was to determine if selected locations for new construction on Kwajalein Island were contaminated by petroleum hydrocarbons as suspected and, if so, whether bioremediation appeared to be a feasible technology for environmental restoration. Two different sites were evaluated: (1) the site planned freshwater production facility and (2) a site adjacent to an aboveground diesel fuel storage tank. Within the proposed construction zone for the freshwater production facility (a.k.a desalination plant), total petroleum hydrocarbons (TPH) where either absent or at low levels. Characterization data for another potential construction site adjacent to an aboveground diesel fuel storage tank southeast of the old diesel power plant revealed high concentrations of diesel fuel in the soil and groundwater beneath the site. Results of this investigation indicate that there are petroleum-contaminated soils on Kwajalein Island and bioremediation appears to be a viable environmental restoration technique. Further experimentation and field demonstration are required to determine the design and operating conditions that provide for optimum biodegradation and restoration of the petroleum-contaminated soils. 17 refs., 7 figs., 26 figs.

NAS battery demonstration at American Electric Power:a study for the DOE energy storage program.
The first U.S. demonstration of the NGK sodium/sulfur battery technology was launched in August 2002 when a prototype system was installed at a commercial office building in Gahanna, Ohio. American Electric Power served as the host utility that provided the office space and technical support throughout the project. The system was used to both reduce demand peaks (peak-shaving operation) and to mitigate grid power disturbances (power quality operation) at the demonstration site. This report documents the results of the demonstration, provides an economic analysis of a commercial sodium/sulfur battery energy storage system at a typical site, and describes a side-by-side demonstration of the capabilities of the sodium/sulfur battery system, a lead-acid battery system, and a flywheel-based energy storage system in a power quality application.

Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

Optimizing Steam & Condensate System: A Case Study
Optimization of Steam & Condensate systems in any process plant results in substantial reduction of purchased energy cost. During periods of natural gas price hikes, this would benefit the plant in controlling their fuel budget significantly, irrespective of the plant's size. This paper highlights the efforts taken by the management of a medium sized specialty chemicals plant in North East Louisiana. This site spent over $19 million in 2007 ($13.7 million for natural gas & $5.6 million for electricity). The site generates steam for its process operation from 3 gas fired boilers at 525-psig pressure. The steam is consumed at 5 process areas; Acid, Basics, Crystals, Derivatives & Hydrogen plants. All of the process areas recover condensate inside their area, utilize it partially, and drain the rest into the sewer. Boiler Feed Water (BFW) is supplied from the water treatment plant located at the Boiler House. The optimization study was conducted at this site, between Jul - Sep 2008, to identify opportunities to reduce the energy cost and to improve the steam system's reliability. The study identified 5 energy cost optimization opportunities that would result in a total cost savings of $1,181,000 annually. The initial estimates indicated that all the 5 projects recommended by the study would have simple payback periods of less than 2 years. This case study is a good example and motivation for all engineers and managers who are responsible for maintaining the efficiency and reliability of small and medium sized steam systems.

Implementing CHP in Louisiana: A Case Study
The objective of this research is to evaluate issues related to implementing CHP systems in Louisiana. A case study is used to show the system design, economic analysis and permitting process. The implementation process will focus on the air permitting and the utility interconnection agreements for rural Louisiana. The development of general guidelines on CHP implementation in Louisiana will provide insight to many potential CHP adopters in the state of Louisiana. The methodology used involves researching current Federal and Louisiana state policies that regulate the air permitting and utility regulation for CHP systems. After the appropriate air permits and qualification for grid connection are identified, the next step in the process of solving the problem will be to locate appropriate contacts within the appropriate agencies. The final step of the problem solving will be to interview the appropriate personnel to identify the procedures that each department follows to implement CHP systems.

Radon mitigation studies: South Central Florida demonstration. Final report, November 1987-January 1991
The report gives results of an EPA radon mitigation project involving 14 slab-on-grade houses in Polk County, FL, having indoor radon levels of 320-3810 Bq/cu m (8.7-103 pCi/L), using sub-slab depressurization (SSD) in a variety of applications to evaluate optimal design criteria to be recommended as cost-effective and capable of reducing indoor radon concentrations in houses built over compacted soil fills. For all houses, obvious accessible radon entry points were sealed, and 53-90 L (12-20 gal.) suction pits were dug into the fill material. Two of the houses were mitigated with exterior horizontal suction holes drilled through the stem walls. In four houses, one or more suction pipes were in the garage. The remainder of the interior suction holes were in closets or some other unobtrusive location. Except for the two houses with exterior systems, the other 12 had mitigation fans in the attic. In-line centrifugal fans were used to mitigate each house, although a larger radial blower was installed overnight for experimental purposes in one house, and a vaccumcleaner was used to simulate a larger suction in another house for pressure field measurements only. Post-mitigation worst-case radon concentrations in these houses ranged from 40 to 290 Bq/cu m.

Dry Storage Demonstration for High-Burnup Spent Nuclear Fuel: Feasibility Study
Initially, casks for dry storage of spent fuel were licensed for assembly-average burnup of about 35 GWd/MTU. Over the last two decades, the discharge burnup of fuel has increased steadily and now routinely exceeds 45 GWd/MTU. This feasibility study examines the options available for conducting a confirmatory experimental program supporting regulatory acceptance of practical approaches for storing, and later transporting, spent fuel with burnup well in excess of 45 GWd/MTU under a dry, inert atmosphere.

Case study of slope failures at Spilmans Island
This paper presents a case study for a dredge disposal site called Spilmans Island, located along the Houston-Galveston Ship Channel, east of Houston. Initially classified as a sand bar in the San Jacinto River, Spilmans Island evolved in recent years with the construction of perimeter levees to contain the flow of materials produced from dredging operations. These levees were often constructed on soft dredged sediments, and as the levees were raised, occasionally slope failures occurred. The objectives of this paper are to illustrate the importance of reconstructing the history of a site as a basis for geotechnical analyses, and to demonstrate the significance of keeping accurate records of past investigations, construction activities, slope failures and subsequent remedial measures. The results of the geotechnical investigation described in this paper offer a clear example of how such data can be used to provide reliable predictions on the stability conditions of raised levees.

In situ vitrification demonstration at Pit 1, Oak Ridge National Laboratory. Volume 1: Results of treatability study
A treatability study was initiated in October 1993 to apply in situ vitrification (ISV) to at least two segments of Oak Ridge National Laboratory (ORNL) seepage Pit 1 by the end of fiscal year (FY) 1995. This treatability study was later extended to include all of Pit 1 and was performed to support a possible Interim Record of Decision or removal action for closure of one or more of the seepage pits and trenches beginning as early as FY 1997. This treatability study was carried out to establish the field-scale technical performance of ISV for (1) attaining the required depth, nominally 15 ft, to incorporate source contamination within and beneath the pits; (2) demonstrating field capability for the overlap of melt settings which will be necessary to achieve fused, melted segments of the source contamination; (3) demonstrating off-gas handling technology for accommodating and minimizing the volatilization of {sup 137}Cs; (4) demonstrating adequate site characterization techniques to predict ISV melting kinetics, processing temperatures, and product durability; and (5) promoting public acceptance of ISV technology by demonstrating its safety, implementability, site impacts, and air emissions and by coordinating the treatability study within the regulatory closure process. In April 1996 an expulsion of an estimated 10% of the 196 Mg (216 tons) melt body occurred resulting in significant damage to ISV equipment and, ultimately, led to an indefinite suspension of further ISV operations at Pit 1. This report summarizes the technical accomplishments and status of the project in fulfilling these objectives through September 1997.

Retrocommissioning Case Study - Applying Building Selection Criteria for Maximum Results
Commissioning of existing buildings, or retrocommissioning is a systematic process to identify operational and maintenance (O&M) improvements that optimize building performance and ensure that building systems function together efficiently and effectively (Haasl, Sharp 1999). This paper presents a case study of a utility-funded retrocommissioning evaluation on a 125,000 SF office facility in La Mesa, California. The commissioning process consisted of site visits, interviews with facility staff, data collection and analysis, recommendation of energy conservation measures, and verification of savings. The study identified 13 deficiencies and recommended a suite of three O&M measures, one capital improvement measure and five other measures. The measures selected and implemented by the owner resulted in annual projected savings of 238,000 kWh (9.9%) and utility cost savings of $20,000 (6.9%)1, with a simple payback of 0.7 years. The project also demonstrated the value of applying rigorous building selection criteria to obtain cost-effective results. This paper profiles the project and discusses lesson learned.

Building-integrated photovoltaics: A case study
In 1992, Kiss Cathcart Anders Architects performed a study for NREL on Building-Integrated Photovoltaics (BIPV) issues as seen from the perspective of the building community. In general, the purpose of the study was to list major issues and potential applications; by it`s nature it asked more questions than it answered. This second phase study was to produce quantitative data on the performance of specific BIPV systems. Only roof systems are evaluated. The energy performance, construction cost and simple payback for five different BIPV roof options are evaluated in six different locations: Oakland, New York, Miami, Phoenix, Chicago, and Cincinnati. The roof options evaluated include the following: single-glazed PV roof using glass-substrate PVs; double-glazed PV roof with insulating PV modules; ballasted roof-mounted system; sawtooth light monitor roof with indirect north daylighting; sawtooth roof with north light and active heat recovery.

Steam System Improvement: A Case Study
Along with the shortage of conventional energy sources, efforts have been sought to use energy in a rational manner. Whereas the biggest energy consumption is in the industrial sector, various techniques to reduce energy have been searched. For industries, this will result in the reduction of production cost. In industry where steam is utilized, the steam production and distribution system consumes a significant portion of energy. Therefore, optimization of steam system is among the biggest energy saving potential in industry. The optimization measures can be categorized into two methods, i.e. (1) no cost/low cost that can be done through a better maintenance and improvement of operating conditions, and (2) major improvement that requires a significant amount of investment, that includes the modification of process and major equipment. Since energy saving is an endless effort, new levels of energy efficiency standards are being set year after year. Therefore, repeated studies should be made to identify energy saving potential. Modern instruments allow the energy specialists to conduct an in-depth survey to identify energy performance. This paper highlights the findings of the study in a steam generation and distribution system of a crude oil stabilization unit. With the annual budget of $8.3 million, the unit is handling about 600,000 barrels crude oil per day from an offshore platform. The study identified an opportunity of annual saving amounting to $1,115,300. Though the finding is specific to a single site, the basics of steam system analysis are applicable to any steam system. The steam system should be reviewed year after year to identify more energy wastes and to improve efficiency of steam system, thus reducing the energy cost. At the same time this will also help save the environment.
Venkatesan, V. V.; Leigh, N.
The industrial sector consumes the largest share of the world's energy. The pulp and paper industry is one of the five most energy-intensive industries in the world. Therefore, optimum energy efficiency plays a pivotal role in the profitability of this sector. Also, energy cost accounts for a significant share in production cost in pulp and paper industries. This paper highlights the findings of a study done on the steam system of a paper mill (covering steam generation, steam distribution and steam usage) where steam generation accounts for 85% of the total energy used. Therefore, optimization of the steam system has the biggest energy saving potential. This paper mill produces 40,000 pounds of steam at 600 psig and distributes it to the paper-making process at various pressure levels. This New England paper mill spends approximately $1.9 million every year on its steam system. The study identified an opportunity to save the plant steam costs in the amount of 12%. Among the identified saving measures, there are some measures that can be done through better maintenance and improvement of operating conditions. The average payback period to implement the identified saving measures is 12 months. In addition to this, upon the implementation of the proposed measures, the paper mill can reduce its carbon emissions in the amount of 500 tons per year and thus, can help save the environment as well.

CIM-EARTH : Framework and case study.
General equilibrium models have been used for decades to obtain insights into the economic implications of policies and decisions. Despite successes, however, these economic models have substantive limitations. Many of these limitations are due to computational and methodological constraints that can be overcome by leveraging recent advances in computer architecture, numerical methods, and economics research. Motivated by these considerations, we are developing a new modeling framework: the Community Integrated Model of Economic and Resource Trajectories for Humankind (CIM-EARTH). In this paper, we describe the key features of the CIM-EARTH framework and initial implementation, detail the model instance we use for studying the impacts of a carbon tax on international trade and the sensitivity of these impacts to assumptions on the rate of change in energy efficiency and labor productivity, and present results on the extent to which carbon leakage limits global reductions in emissions for some policy scenarios.

Steam System Optimization : A Case Study
The steam system optimization (generation, distribution, use and condensate return) offers a large opportunity for action to comply with the new levels of energy efficiency standards. Superior design and improved maintenance practices are the two main sources of savings in steam systems. Increased competition no longer permits an industry to survive with energy waste that could be eliminated. This paper highlights the study findings of the steam system in a plant from the Food industry. The steam system operates with an annual budget of $1.9 million. Normal steam demand ranges between 80,000 to 85,000 lb/hr. The steam system analysis identified energy savings worth $270,000 per year. The optimization measures were in two categories: No cost/low cost optimizations that can be done through a better maintenance and improved operating condition Major improvements that require a significant investment, and includes the modification of the process and major equipment.

Steam System Optimization: A Case Study
This paper highlights the study findings in a steam system in a plant from a multinational Petrochemical giant in an European country. The steam system operates with an annual budget of $8.9 million (local currency was converted to US Dollars). Normal steam demand ranges from 500,000 to 600,000 lbs/hr. 380,000 lbs/hr is imported from an outside power plant and 170,000 lbs/hr is internally generated as waste heat recovery. The steam system analysis identified energy savings worth of $2,400,000 per year. The optimization measures were in two categories: no cost / low cost that can be done through better maintenance and improvement of operating conditions. major improvement that requires a significant amount of investment, that includes the modification of process and major equipment. Though the findings are specific to a single site, the basics of steam system analysis are applicable to any steam system. A critical review on any steam system always identifies controllable wastes. Improvements in steam system efficiency equal reduced energy consumption and saved environment.

An open source software selection process and a case study
In this study, I design an empirical open source software selection process, which reuses some ideas from Commercial Off-the-Shelf selection methods and addresses the characteristics of the open source software. Basically, it consists of three basic steps: identification, screening and evaluation. The identification step is to find all possible alternatives to open source software that can meet the high level requirements. The next step is screening, in which the refined requirements are applied to filter the alternatives. The evaluation step is based on the Analytic Hierarchy Process, in which the alternatives are inspected from functional suitability, source code, support strength and popularity. In more detail, under functionality suitability criterion, alternatives to open source software are evaluated in viewing of how much functionality can fit in with the functional user requirements. The source code of the alternatives is evaluated from six criteria: programming language, code size, code comment, code intra-module complexity and code inter-module complexity. The evaluation of support strength depends on the evaluation of field support and support resources. The field support includes commercial support and community support. The community support specifically refers to the direct responses from the community to the support requests. Aside from field support, open source software projects also provide various support-related resources such as, documents, wiki, blog, etc. To determine the popularity of the alternatives, I evaluate them from software use, development participation and web popularity. In the case study, I utilize the process to select the best open source unified modeling language tool from the ten alternatives for the software development process. After the screening phase, the four competitive alternatives, BOUML, ArgoUML, UMLet and Violet, are evaluated from functionality, source code, support strength and popularity criteria. The evaluation result indicates that ArgoUML is the best tool for the requirement. The case study demonstrates the effectiveness of the selection process. Various important attributes of open source software are taken into consideration systematically and the final decision is reached based on comprehensive investigation and analysis. The process provides an operable solution to the open source selection problem in practice.

Industrial process heat case studies. [PROSYS/ECONMAT code
Commercially available solar collectors have the potential to provide a large fraction of the energy consumed for industrial process heat (IPH). Detailed case studies of individual industrial plants are required in order to make an accurate assessment of the technical and economic feasibility of applications. This report documents the results of seven such case studies. The objectives of the case study program are to determine the near-term feasibility of solar IPH in selected industries, identify energy conservation measures, identify conditions of IPH systems that affect solar applications, test SERI's IPH analysis software (PROSYS/ECONOMAT), disseminate information to the industrial community, and provide inputs to the SERI research program. The detailed results from the case studies are presented. Although few near-term, economical solar applications were found, the conditions that would enhance the opportunities for solar IPH applications are identified.

Study of costs associated with alternative fuels development: A case study. Research report
The primary objective of the study was to conduct a case study of large-scale fuel conversion project to assess selected costs and related issues. An inventory of public transit agencies engaged in demonstration projects involving alternative fuels as conducted with representative sample of large public transit systems in the nation. Included in the survey were questions pertaining to fuel supply arrangements, fuel reserve storage requirements and/or deficiencies; future plans for managing energy resources and costs associated with fuel conversion/alternative fuels use -- whether planned or currently in operation. The case study approach was used to document the methodological and logistical problems encountered during the course of projects involving alternative fuels use compared with a control sample using diesel fuel. Monthly status reports on the alternative fuel project included data on accumulated mileage, road calls/unscheduled maintenance, fuel consumption, fuel cost per mile, alternative fuel purchases, schedule of activities, personnel, safety , and diesel emission test results. The data collected indicate several conclusions and future implications about technical and safety issues associated with the testing and use of liquefied natural gas (LNG).

Biosphere reserves in action: Case studies of the American experience
For nearly 20 years, biosphere reserves have offered a unique framework for building the knowledge, skills, and attitudes required for conservation and sustainable use of ecosystems. The 12 case studies in this volume chronicle many of the cooperative efforts to implement the biosphere reserve concept in the United States. Considered together, these efforts involve more than 20 types of protected areas, and the participation of all levels of government, and many private organizations, academic institutions, citizens groups, and individuals. Biosphere reserves are multi-purpose areas that are nominated by the national committee of the Man and the Biosphere Program (MAB) and designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to serve as demonstration areas for cooperation in building harmonious relationships between human activities and the conservation of ecosystems and biological diversity. Each biosphere reserve exemplifies the characteristic ecosystems of one of the worlds biogeographical regions. It is a land or coas%arine area involving human communities as integral components and including resources managed for objectives ranging from complete protection to intensive, yet sustainable development. A biosphere reserve is envisioned as a regional ''landscape for learning'' in which monitoring, research, education, and training are encouraged to support sustainable conservation of natural and managed ecosystems. It is a framework for regional cooperation involving government decisionmakers, scientists, resource managers, private organizations and local people (i.e., the biosphere reserve ''stakeholders''). Finally, each biosphere reserve is part of a global network for sharing information and experience to help address complex problems of conservation and development. The 12 case studies presented in this report represent only a few of the possible evolutions of a biosphere reserve in its efforts to reach out to the local and regional community. As you have read, some have had great success, while others consider their successes almost negligible. All document tremendous effort from many people to improve the communication among landowners, land managers, scientists, and any others interested in the health and well-being of the natural and human environment of the biosphere reserve.

Shale oil production system reference case study. Final report
Material balances, utility balances, and overall processing schemes were developed for two reference shale oil production systems. For both cases, crushed and sized oil shale is fed into a mix of surface retorts specified for this study, which handle both coarse and fine ore. Case 1A produces an upgraded crude product suitable for refinery feedstock, and Case 1B produces a crude shale oil. The reference system uses room-and-pillar mining, three different types of retorts not unlike those proposed for the White River Shale Project on Federal Lease Tracts U-a and U-b, a straightforward upgrading of the raw shale oil to a refinery feedstock syncrude, and pipeline transportation of that product. In addition to the production of an upgraded product, there is also a modified system for producing raw shale oil that is minimally upgraded for pipeline transportation purposes. The capital cost estimate for the two reference cases has 26 cost elements, excluding, for example, any land or finance costs. A more complete list of excluded cost elements is provided in Section VII. The two distinct cases, production of raw and upgraded shale oil, were included to avoid foreclosing the issue of on- or off-site upgrading. The difference in estimated capital cost ($795M vs. $875M) amounts to about 10 percent.

Wind for Schools Project Funding Case Studies Wind for Schools Project Funding Case Studies August 26, 2013 The Wind for Schools project is part of the U.S. Department of Energy's (DOE's) Wind Powering America initiative. Since 2005, DOE provided funding for Wind Applications Centers in 11 Wind for Schools states, introducing teachers, students, and communities to wind energy applications and benefits. This Wind for Schools funding supported the project; it was not used to purchase turbines and equipment. Individual school champions emerged to find local funding mechanisms to purchase and install their turbines. On October 1, 2013, DOE will no longer fund the project; therefore, we feel that it is important to document the funding sources utilized by these states to purchase and install Wind for Schools project turbines.

Deploying High Penetration Photovoltaic Systems: A Case Study
Photovoltaic (PV) system capacity penetration, or simply 'penetration,' is often defined as the rated power output of the aggregate PV systems on a distribution circuit segment divided by the peak load of that circuit segment. Industry experts agree that a single value defining high penetration is not universally applicable. However, it is generally agreed that a conservative value to designate high penetration is the condition when the ratio of aggregate PV systems ratings to peak load exceeds 15%. This case study illustrates the case of a distribution feeder which is able to accommodate a traditional capacity penetration level of 47%, and perhaps more. New maximum penetration levels need to be defined and verified and enhanced definitions for penetration on a distribution circuit need to be developed. The new penetration definitions and studies will help utility engineers, system developers, and regulatory agencies better agree what levels of PV deployment can be attained without jeopardizing the reliability and power quality of a circuit.

Productivity index and field behavior: a case study
This study is an investigation of different factors' phics. influence on the productivity index and its behavior. The objectives of this research are (1) to develop an overview of how different factors influence the productivity index', and (2) to explain the irrational behavior of the productivity index in a case study presented. The problem has its origin in a field in north Africa, where irrational behavior of the productivity index (PI) has made it difficult to forecast the field performance. By irrational behavior we meant that the PI ants the opposite of what is expected. Normally we think PI will increase when the production oil rate of the field increases, at the same pressure drawdown. Or for the same well, PI should be constant over time. In some wells in this particular field we can see the P1 increase as production oil rate decreases and vice versa. Numerical simulation was used to simulate the influence different factors had on the productivity index, and to match wellness PI's with calculated PI's from field data in the case study. An overview of which factors can cause the P1 to go in unexpected directions is presented. Finally the theory obtained about the PI behavior is linked to the case study, and the E6incon-ect'' behavior of the PI is explained. It was shown that transient flow and two-phase flow are the two main reasons for the productivity index to decrease as production oil rate increases. It was also shown that dual porosity, non-Darcy flow, permeability changes, formation compressibility, and skin affect the length of the transient flow period and the magnitude of the difference between transient PI and pseudo steady state (PSS) PI. The behavior of the PI in the field case presented is explained by the transient flow effect and bad test data.

Case studies of geothermal leasing and development on federal lands
In response to a widely expressed need to examine the impact of the federal regulatory system on the rate of geothermal power development, the Department of Energy-Division of Geothermal Energy (DGE) has established a Streamlining Task Force in cooperation with appropriate federal agencies. The intent is to find a way of speeding development by modification of existing laws or regulations or by better understanding and mechanization of the existing ones. The initial focus was on the leasing and development of federal lands. How do the existing processes work? Would changes produce positive results in a variety of cases? These are questions which must be considered in a national streamlining process. This report presents case studies of federal leasing actions on seven diverse locations in the western region. Characteristics of existing high geothermal potential areas are quite diverse; geography, environment, industry interest and the attitudes and activities of the responsible federal land management agencies and the interested public vary widely. Included are descriptions of post and current activities in leasing exploration and development and discussions of the probable future direction of activities based on current plans. Implications of these plans are presented. The case studies were based on field interviews with the appropriate State and District BLM officer and with the regional forester's office and the particular forest office. Documentation was utilized to the extent possible and has been included in whole or in part in appendices as appropriate.

Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part 2: Case Demonstration for a Typical Climate System
In Part 1 of this paper, the theoretical models, integrating the fan airflow, fan head, air leakage factors, are developed to analyze the impacts of the static pressure reset on both pressure dependent and pressure independent terminal boxes. In this part, a simulated air handling unit (AHU) system in Omaha NE is used to demonstrate the energy savings performance in one typical climate year. This AHU system has a static pressure reset system and two constant static pressure systems, one having pressure dependent terminal boxes and one having pressure independent terminal boxes. These simulated systems were compared mainly on the basis of fan power energy consumption and thermal energy consumption in totally a year. The example presents a good agreement with the theoretical model and simulation results. It was also shown that static pressure reset provides a promising and challenging way for the energy performance in VAV system.

The crisis atmosphere surrounding electricity availability in California during the summer of 2001 produced two distinct phenomena in commercial energy consumption decision-making: desires to guarantee energy availability while blackouts were still widely anticipated, and desires to avoid or mitigate significant price increases when higher commercial electricity tariffs took effect. The climate of increased consideration of these factors seems to have led, in some cases, to greater willingness on the part of business decision-makers to consider highly innovative technologies. This paper examines three case studies of innovative technology adoption: retrofit of time-and-temperature signs on an office building; installation of fuel cells to supply power, heating, and cooling to the same building; and installation of a gas-fired heat pump at a microbrewery. We examine the decision process that led to adoption of these technologies. In each case, specific constraints had made more conventional energy-efficient technologies inapplicable. We examine how these barriers to technology adoption developed over time, how the California energy decision-making climate combined with the characteristics of these innovative technologies to overcome the barriers, and what the implications of hurdling these barriers are for future energy decisions within the firms.

The geoscience data gathered in the drilling and testing of seven geothermal wells suggest that the Raft River thermal reservoir is: (a) produced from fractures found at the contact metamorphic zone, apparently the base of detached normal faulting from the Bridge and Horse Well Fault zones of the Jim Sage Mountains; (b) anisotropic, with the major axis of hydraulic conductivity coincident to the Bridge Fault Zone; (c) hydraulically
Ground-source heat pump case studies and utility programs
Ground-source heat pump systems are one of the promising new energy technologies that has shown rapid increase in usage over the past ten years in the United States. These systems offer substantial benefits to consumers and utilities in energy (kWh) and demand (kW) savings. The purpose of this study was to determine what existing monitored data was available mainly from electric utilities on heat pump performance, energy savings and demand reduction for residential, school and commercial building applications. In order to verify the performance, information was collected for 253 case studies from mainly utilities throughout the United States. The case studies were compiled into a database. The database was organized into general information, system information, ground system information, system performance, and additional information. Information was developed on the status of demand-side management of ground-source heat pump programs for about 60 electric utility and rural electric cooperatives on marketing, incentive programs, barriers to market penetration, number units installed in service area, and benefits.

Evaluation Of Microdosing Strategies For Studies In Preclinical Drug Development: Demonstration Of Linear Pharmacokinetics In Dogs Of A Nucleoside Analogue Over A 50-Fold Dose Range
The technique of accelerator mass spectrometry (AMS) was validated successfully and utilized to study the pharmacokinetics and disposition in dogs of a preclinical drug candidate (Compound A), after oral and intravenous administration. The primary objective of this study was to examine whether Compound A displayed linear kinetics across sub-pharmacological (microdose) and pharmacological dose ranges in an animal model, prior to initiation of a human microdose study. The AMS-derived disposition properties of Compound A were comparable to data obtained via conventional techniques such as LC-MS/MS and liquid scintillation counting analyses. Thus, Compound A displayed multiphasic kinetics and possessed low plasma clearance (4.4 mL/min/kg), a long terminal elimination half-life (19.4 hr) and high oral bioavailability (82%). Currently there are no published comparisons of the kinetics of a pharmaceutical compound at pharmacological versus sub-pharmacological doses employing microdosing strategies. The present study thus provides the first description of the pharmacokinetics of a drug candidate assessed under these two dosing regimens. The data demonstrated that the pharmacokinetic properties of Compound A were similar following dosing at 0.02 mg/kg as at 1 mg/kg, indicating that in the case of Compound A, the kinetics of absorption, distribution and elimination in the dog appear to be linear across this 50-fold dose range. Moreover, the exceptional sensitivity of AMS provided a pharmacokinetic profile of Compound A, even following a microdose, which revealed aspects of the disposition of this agent that were inaccessible by conventional techniques. The applications of accelerator mass spectrometry (AMS) are broad ranging and vary from studying environmental and ecological issues such as the isotopic composition of the atmosphere, soil and water (Hughen et al., 2000; Beck et al., 2001; Keith-Roach et al., 2001; Mironov et al., 2002), to archaeology and volcanology (Stafford et al., 1984; Vogel et al., 1990; Smith et al., 1999) to its use as a bioanalytical tool for nutritional research (Buchholz et al., 1999; Deuker et al., 2000; Weaver and Liebman, 2002). Biomedical applications of AMS and its use in the arena of pharmaceutical research also have been detailed in review articles (Barker and Garner, 1999; Garner, 2000; Turteltaub and Vogel, 2000). To date, most studies on the metabolism and disposition of xenobiotics by AMS have focused on how carcinogens bind to DNA and proteins to form adducts (Turteltaub et al., 1990, 1997; Frantz et al., 1995; Dingley et al., 1999; Li et al., 2003). Its application to the field of pharmaceutical sciences has been limited to a few studies (Kaye et al., 1997; Young et al., 2001; Garner et al., 2002). However, the pharmaceutical industry is becoming increasingly aware of the potential benefits that may accrue from the ultra high sensitivity afforded by AMS in terms of evaluating the pharmacokinetics of lead drug candidates in early development. Specifically, AMS allows administration of sub-pharmacological doses (microdoses) of carbon-14 or tritium-labeled investigational drugs to animals or humans at radiologically insignificant levels with the goal of obtaining preliminary information regarding the absorption, distribution, metabolism, and excretion of test compounds (Turteltaub and Vogel, 2000). An unresolved issue, however, is whether the pharmacokinetics determined following a microdose are representative of those following a conventional (pharmacological) dose (Lappin and Garner, 2003). This paper examines the linearity of kinetics of an antiviral nucleoside analogue, Compound A, across sub-pharmacological and pharmacological dose ranges in the dog prior to initiation of a human microdose study. The specific objectives of this study, therefore, were (1) to assess the pharmacokinetics of Compound A in dogs by a conventional dosing approach utilizing LC-MS/MS for sample analysis, (2) to assess the pharmacokinetics of Compound A in dogs by the microdose approach utilizing AMS for sample ana

Modelling renewable electric resources: A case study of wind
The central issue facing renewables in the integrated resource planning process is the appropriate assessment of the value of renewables to utility systems. This includes their impact on both energy and capacity costs (avoided costs), and on emissions and environmental impacts, taking account of the reliability, system characteristics, interactions (in dispatch), seasonality, and other characteristics and costs of the technologies. These are system-specific considerations whose relationships may have some generic implications. In this report, we focus on the reliability contribution of wind electric generating systems, measured as the amount of fossil capacity they can displace while meeting the system reliability criterion. We examine this issue for a case study system at different wind characteristics and penetration, for different years, with different system characteristics, and with different modelling techniques. In an accompanying analysis we also examine the economics of wind electric generation, as well as its emissions and social costs, for the case study system. This report was undertaken for the {open_quotes}Innovative IRP{close_quotes} program of the U.S. Department of Energy, and is based on work by both Union of Concerned Scientists (UCS) and Tellus Institute, including America`s Energy Choices and the UCS Midwest Renewables Project.

Diagnosis of condensation-induced waterhammer: Case studies
This guidebook provides reference material and diagnostic procedures concerning condensation-induced waterhammer in nuclear power plants. Condensation-induced waterhammer is the most damaging form of waterhammer, and its diagnosis is complicated by the complex nature of the underlying phenomena. In Volume 1, the guidebook groups condensation-induced waterhammers into five event classes which have similar phenomena and levels of damage. Diagnostic guidelines focus on locating the event center where condensation and slug acceleration take place. Diagnosis is described in three stages: an initial assessment, detailed evaluation and final confirmation. Graphical scoping analyses are provided to evaluate whether an event from one of the event classes could have occurred at the event center. Examples are provided for each type of waterhammer. Special instructions are provided for walking down damaged piping and evaluating damage due to waterhammer. To illustrate the diagnostic methods and document past experience, six case studies have been compiled in Volume 2. These case studies, based on actual condensation-induced waterhammer events at nuclear plants, present detailed data and work through the event diagnosis using the tools introduced in the first volume. 20 refs., 21 figs., 6 tabs.

Preconceptual design study for solidifying high-level waste: Appendices A, B and C West Valley Demonstration Project
This report presents a preconceptual design study for processing radioactive high-level liquid waste presently stored in underground tanks at Western New York Nuclear Service Center (WNYNSC) near West Valley, New York, and for incorporating the radionculides in that waste into a solid. The high-level liquid waste accumulated from the operation of a chemical reprocessing plant by the Nuclear Fuel Services, Inc. from 1966 to 1972. The high-level liquid waste consists of approximately 560,000 gallons of alkaline waste from Purex process operations and 12,000 gallons of acidic (nitric acid) waste from one campaign of processing thoria fuels by a modified Thorex process (during this campaign thorium was left in the waste). The alkaline waste contains approximately 30 million curies and the acidic waste contains approximately 2.5 million curies. The reference process described in this report is concerned only with chemically processing the high-level liquid waste to remove radionuclides from the alkaline supernate and converting the radionuclide-containing nonsalt components in the waste into a borosilicate glass.

Commercializing government-sponsored innovations: Twelve successful buildings case studies
This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies. 27 refs., 21 figs., 4 tabs.

Shaping urban form without zoning: a case study of houston
Houston is the only major city in North America without zoning. The growth of Houston illustrates a traditional free market philosophy in which land use zoning is seen as a violation to private property and personal liberty. This dissertation explores how the lack of zoning has an impact on land use and urban form in Houston. It is based on a theoretical framework derived from economics and public policy theories for institutional analyses of land development controls. The dissertation uses cluster analysis integrating socioeconomic factors from census data to select three case study neighborhoods, and then applies GIS to analyze their urban form spatial characteristics with spatial data from Houston Planning Department. It also uses qualitative methods such as archives and documentations for the three neighborhoods. The study investigates the change of urban form in three case study neighborhoods over two decades. It also explores how local land use policies made by both the local government and non-governmental sectors shape urban form in Houston. The study results show that despite the citys lack of zoning, local land use regulatory policies made by the municipality have significant influence on urban development. Additionally, civic and private organizations such as super neighborhoods and homeowner associations fill the gaps left by the lack of land use zoning. These two aspects contribute to land use planning and urban form of the city. Houston presents a contradiction of limited government intervention and public investments and subsidies. Land use controls by private contract and by government legislative intervention are not mutually exclusive or immutable. The study finds that it is difficult to achieve mixed race and income neighborhoods, even without zoning. Equity goals are not met in market approaches. Deed restrictions might be better at facilitating property sales and maintenance than at improving community welfare and governance. From the theoretical perspective, the study argues that a spectrum of market solutions and planning approaches at the ends are more relevant than the bipolarity view. Equity goals are not met in market approaches. For welfare and rights, public planning intervention is necessary. The market might provide physical land use diversity, but it fails to support socioeconomic diversity.

NREL Case Study Leads to International Partnership (Fact Sheet)
In 2012, NREL analysts produced a case study, "Integrating Variable Renewable Energy in Electric Power Markets: Best Practices from International Experience," which drew upon dozens of interviews with international experts involved in crafting effective policies and markets. The report proposed a cross-cutting initiative to transform the world's power systems by implementing two complementary strategies: the large?scale deployment of renewable energy, and a combination of comprehensive energy efficiency and smarter grids. This recommendation led to the launch of the 21st Century Power Partnership in April 2012, and its membership has since grown to include Denmark, Finland, Germany, India, Mexico, Spain, and the United States. NREL, together with its affiliated Joint Institute for Strategic Energy Analysis, are the operating agents.
ARýHockey: A Case Study of Collaborative Augmented Reality
This paper introduces a collaborative augmented reality (AR) system for realtime, interactive operations. AR enables us to enhance physical space with computer generated virtual space. In addition, the collaborative AR makes multiple participants to simultaneously share a physical space surrounding them and a virtual space, visually registered with the physical one. They can also communicate each other through the mixed space. This paper describes an AR 2 Hockey (Augmented Reality AiR Hockey) system where players can share a physical game field, mallets, and a virtual puck to play an air-hockey game, as a case study of collaborative AR system. Since realtime, accurate registration between both spaces and players is crucial for the collaborations, a video-rate registration algorithm is implemented with magnetic headtrackers and video cameras attached to optical see-through HMDs. The configuration of the system and the details of registration are described. Our experimental collaborati...

Electricity generation and environmental externalities: Case studies, September 1995
Electricity constitutes a critical input in sustaining the Nation`s economic growth and development and the well-being of its inhabitants. However, there are byproducts of electricity production that have an undesirable effect on the environment. Most of these are emissions introduced by the combustion of fossil fuels, which accounts for nearly 70 percent of the total electricity generated in the United States. The environmental impacts (or damages) caused by these emissions are labeled environmental ``externalities.`` Included in the generic term ``externality`` are benefits or costs resulting as an unintended byproduct of an economic activity that accrue to someone other than the parties involved in the activity. This report provides an overview of the economic foundation of externalities, the Federal and State regulatory approaches, and case studies of the impacts of the externality policies adopted by three States.
Geothermal field case studies that document the usefulness of models in predicting reservoir and well behavior
The geothermal industry has shown significant interest in case histories that document field production histories and demonstrate the techniques which work best in the characterization and evaluation of geothermal systems. In response to this interest, LBL has devoted a significant art of its geothermal program to the compilation and analysis of data from US and foreign fields (e.g., East Mesa, The Geysers, Susanville, and Long Valley in California; Klamath Falls in Oregon; Valles Caldera, New Mexico; Cerro Prieto and Los Azufres in Mexico; Krafla and Nesjavellir in Iceland; Larderello in Italy; Olkaria in Kenya). In each of these case studies we have been able to test and validate in the field, or against field data, the methodology and instrumentation developed under the Reservoir Technology Task of the DOE Geothermal Program, and to add to the understanding of the characteristics and processes occurring in geothermal reservoirs. Case study results of the producing Cerro Prieto and Olkaria geothermal fields are discussed in this paper. These examples were chosen because they illustrate the value of conceptual and numerical models to predict changes in reservoir conditions, reservoir processes, and well performance that accompany field exploitation, as well as to reduce the costs associated with the development and exploitation of geothermal resources. 14 refs., 6 figs.

Optimizing Steam and Condensate System: A Case Study
Optimization of Steam & Condensate systems in any process plant results in substantial reduction in purchased energy cost. During periods of natural gas price hikes, this would benefit the plant in controlling their fuel budget significantly, irrespective of the plants size. This paper highlights the efforts taken by the management of a medium sized specialty chemicals plant in Baton Rouge, LA. This site spent over $5.1 million in 2007 ($2.1 million for natural gas & $3.0 million for electricity). The site is generating steam for its process operation from the two gas fired boilers at 175-psig pressure. The steam is consumed at three of its five process areas. The other two process areas are not significant steam users. Condensate recovery is about 55%, while the system is designed to recover condensate from all steam users. Make-up water is supplied from a Reverse Osmosis (RO) plant. The optimization study was conducted at this site between Mar May 2008, to identify opportunities to reduce the energy cost and to improve the steam systems reliability. The study identified nine energy cost optimization opportunities that would result in a total cost savings of $306,000 annually. The initial estimates indicate that 7 of the 9 projects recommended by the study have simple payback periods of less than one year. This case study is a good example and motivation for all the engineers and managers who are responsible for maintaining the efficiency and reliability of small and medium size steam systems.

Hearing Nano-Structures: A Case Study in Timbral Sonification
We explore the sonification of x-ray scattering data, which are two-dimensional arrays of intensity whose meaning is obscure and non-intuitive. Direct mapping of the experimental data into sound is found to produce timbral sonifications that, while sacrificing conventional aesthetic appeal, provide a rich auditory landscape for exploration. We discuss the optimization of sonification variables, and speculate on potential real-world applications. We have presented a case study of sonifying x-ray scattering data. Direct mapping of the two-dimensional intensity values of a scattering dataset into the two-dimensional matrix of a sonogram is a natural and information-preserving operation that creates rich sounds. Our work supports the notion that many problems in understanding rather abstract scientific datasets can be ameliorated by adding the auditory modality of sonification. We further emphasize that sonification need not be limited to time-series data: any data matrix is amenable. Timbral sonification is less obviously aesthetic, than tonal sonification, which generate melody, harmony, or rhythm. However these musical sonifications necessarily sacrifice information content for beauty. Timbral sonification is useful because the entire dataset is represented. Non-musicians can understand the data through the overall color of the sound; audio experts can extract more detailed insight by studying all the features of the sound.

Energy conserving site design case study: Shenandoah, Georgia. Final report
The case study examines the means by which energy conservation can be achieved at an aggregate community level by using proper planning and analytical techniques for a new town, Shenandoah, Georgia, located twenty-five miles southwest of Atlanta's Hartsfield International Airport. A potentially implementable energy conservation community plan is achieved by a study team examining the land use options, siting characteristics of each building type, alternate infrastructure plans, possible decentralized energy options, and central utility schemes to determine how community energy conservation can be achieved by use of pre-construction planning. The concept for the development of mixed land uses as a passively sited, energy conserving community is based on a plan (Level 1 Plan) that uses the natural site characteristics, maximizes on passive energy siting requirement, and allows flexibility for the changing needs of the developers. The Level 2 Plan is identical with Level 1 plan plus a series of decentraized systems that have been added to the residential units: the single-family detached, the apartments, and the townhouses. Level 3 Plan is similar to the Level 1 Plan except that higher density dwellings have been moved to areas adjacent to central site. The total energy savings for each plan relative to the conventional plan are indicated. (MCW)

Case studies of current trends in development geology
Traditionally, development geologists have been responsible for studying leases, logs, and cores in detail in support of engineering functions. These responsibilities have grown from defining gross reservoir geometries to understanding subtle differences in reservoirs attributed to stratigraphic and structural complexities, depositional environments, and hydrodynamic processes. To handle these increased responsibilities, expertise has become essential in the areas of computer applications, log analysis, modeling, and management of produced water. Examples of the use and application of each area to projects from fields on the west side of the San Joaquin Valley demonstrate current techniques employed by development geologists and the evolution of a development department within Texaco. A study of a property in the South Belridge field on which 330 wells were drilled over a two-year period illustrates how computer resources have become vital in handling the vast amount of data needed to perform detailed geologic studies. Intricate geologic characterization has become essential to optimizing and defining reservoir performance in several fields: (1) Southeast Lost Hills, a complex diagenetic trap; (2) Buena Vista Hills, where log analysis is needed to make reserve estimates and step-out potential meaningful; (3) Midway-Sunset field, for which detailed geology leads to new field-wide models and future prospects. Increasing environmental concern over waste disposal has required an important involvement of development geologists in the geologic and hydrologic aspects of subsurface injection of produced water and other brines in the Santiago Creek field. Instead of providing a training ground for future explorationists, development geology should be viewed as an alternative career with potential for a much greater demand in the future.

A Case Study to Test Mozaik for Different Optimization Problems
We present four different shape optimization problems based on the existing beam port facility of the Penn State Breazeale Reactor and their results obtained by the modular optimization code package, MOZAIK. Each model problem has a different beam tube configuration with the same optimization goal: to determine an optimal D2O moderator tank shape for the given beam tube arrangement that maximizes the thermal neutron beam intensity at the beam tube exit end. In this study, the power of the automated search process was demonstrated and its capabilities were tested. In addition, the performance of the beam port was analyzed using alternative beam tube arrangements. All alternative arrangements indicate that higher thermal neutron beam intensity can be obtained at the beam tube exit end using a smaller volume of D2O in the system than is used in the existing beam port configuration. Moreover, the results show that MOZAIK is ready for deployment to address shape optimization problems involving radiation transport in nuclear engineering applications.

Optimization of Steam & Condensate systems in any continuous-process plant results in substantial reduction in purchased energy cost. During periods of natural gas price hikes, this would benefit the plant in controlling their fuel budget significantly. If planned well, the energy cost savings efforts could also give the spin-off benefit of waste water reduction from the plant. This paper highlights the efforts taken by the management of a medium sized petroleum refinery in Mid-West USA. This site has two sections of process units with tank farms located in between them. The refinery uses its own process off-gases and purchases additional natural gas to fire its Boilers and process heaters. Steam is also generated from the exhaust gases of the process heaters. An optimization study was conducted at this refinery site during Sep Nov 2006, to identify opportunities to reduce the energy cost, to improve the steam systems reliability, and to reduce the waste water loading to the treatment plant. The study identified 8 energy and water use optimization opportunities that would result in a total cost savings of $ 2.67 million annually. The initial estimates indicated that all the projects recommended by the study would have simple payback periods of less than 2 years. The plant management decided to pursue 3 of the 8 recommendations and completed Basic Engineering design during early 2007. The management is interested in pursuing the other identified energy savings opportunities also upon implementing the initial 3 projects. Upon implementing all the identified projects by the study, the refinerys energy use is expected to reduce by 89,900 MMBtu/yr & Water usage would reduce by 38,900 kGals/yr. The reduction of hot condensate dumping to the waste water pond is also expected to save the bug-life in the waste water pond. This case study is a good example and motivation for all the engineers and managers, who are responsible for maintaining the efficiency and reliability of the steam systems in their plants.

Case Study Impact Evaluations of the Industrial Energy Savings Plan
This paper presents the results of a series of five case study impact evaluations of Energy Savings Plan (ESP) industrial energy efficiency projects funded by the Bonneville Power Administration (BPA) and Seattle City Light (City Light). These industrial sector evaluations are among the first in the Pacific Northwest to evaluate both energy and non-energy effects. The projects chosen for evaluation cover a wide range of industrial processes and end-uses. Each industrial setting, the efficiency measures installed and the processes affected are described in this paper. The report presents energy (kWh) and peak demand (kW) savings indexed to changes in production volume, an assessment of non-energy benefits to the participating customer, and cost-effectiveness analyses from four stakeholder perspectives. Levelized cost (expressed in cents per kWh) and benefit-cost ratios were calculated for each project, both including and excluding quantifiable energy non-energy benefits. A summary of conclusions and lessons learned is also provided. The evaluation team included Patrick Lilly of Regional Economic Research Inc., Paresh Parekh of Unicade Inc., D'Arcy Swanson of Pacific Sciences Inc., and Dennis Pearson at Seattle City Light.

Speed Control in Industrial Refrigeration: Theory, Application & Case Studies
It is often standard practice in the field of industrial refrigeration to design and operate systems with little regard toward part-load performance. This approach is understandable, whether viewed from the standpoint of the design engineer, plant manager or chief operator. As long a space temperature and production rates are maintained during peak periods, the refrigeration system is viewed as operating "correctly". The truth is, most refrigeration systems spend some, if not most operating hours at reduced capacity. Screw compressors back off slide valves, evaporator coils utilize back-pressure regulators (BPRs) or liquid solenoids, and condensers cycle fans. Unfortunately, these control methods do not provide the maximum attainable reduction in brake horsepower (BHP) as refrigeration capacity is reduced. This paper will discuss the application of variable speed drive (VSD, also called "variable frequency drive", "adjustable speed drive", "inverter", or simply "freq. drive") technology to capacity control of screw compressors, evaporator fans, and condenser fans. As shown through theory and case study, speed control of these components provides maximum flexibility, control and energy efficiency.

Real Time Pricing Tie Line Control: A Case Study
A Tie Line Control System maintains the purchase quantity of electrical energy an industrial facility buys from a utility company. Implementing an advanced Tie Line Control system automates the buy versus make decision process for an industrial facility in order to optimize the use of energy by either a supply-side method or a demand-side method. If a facility possesses supply-side resources, such as self-generation, the user can choose to maximize on-site energy generation, when it is less expensive than the price offered by the utility. Conversely, when the price to buy energy is less expensive than it is to produce it, a facility may choose to back off on self-generation and buy more energy. One such Advanced Tie Line Control system, designed by Automation Applications, Incorporated (AAI) and installed at a pilot facility, utilizes a real-time pricing utility contract and provides savings approaching one million dollars per year. This paper is a case study of this system implementation and the results achieved.

Case Study: Iran, Islam, the NPT, and the Bomb
The goals of this case study are: (1) To examine the correlation between Iran's nuclear program and clerical statements; (2) To evaluate the importance of these statements; (3) To understand the relationship between policy and fatwas (Islamic decrees); (4) To address the issue of a 'nuclear fatwa'; and (5) To examine how, if at all, Sharia (Islamic law) has influenced Iran's actions or inactions with respect to the Non-Proliferation Treaty (NPT), the International Atomic Energy Agency (IAEA), and Iran's adherence to its IAEA Safeguards Agreements and the Additional Protocol. The Islamic Republic of Iran (hereinafter Iran) is one of two theocracies in the world, the second being Vatican City. Iran's government derives its constitutional, moral, and political legitimacy from Islam. As a result of this theocratic culture, rules are set and interpreted with a much different calibrator than that of the Western world. Islam affects all aspects of Iranian life. This is further complicated by the fact that Islam is not a nationalistic faith, in that many people all over the world believe in and adhere to Islamic principles. As a result, a political system that derives much of its fervor from being nationalistic is caught between two worlds, one within the land boundaries of Iran and the other within a faith that transcends boundaries. Thus, any understanding of Islamic law must first be understood within this delicate balance of nationalism and transcendence. Iran has found itself on the international stage concerning its nuclear program. Because Iran is a theocratic state, it is imperative to examine its political moves, speeches, rights, and obligations through the lens of Islam. This study will examine how Islam plays a role in Iran's dealing with the International Atomic Energy Agency (IAEA), its understanding of the Nuclear Non-Proliferation Treaty (NPT), including parties obligations under Safeguards Agreements and the Additional Protocol, and also provide a recommendation on how to move forward in dealings with Iran based in part on an understanding of Islamic principles.

PFBC Utility Demonstration Project
This report provides a summary of activities by American Electric Power Service Corporation during the first budget period of the PFBC Utility Demonstration Project. In April 1990, AEP signed a Cooperative Agreement with the US Department of Energy to repower the Philip Sporn Plant, Units 3 4 in New Haven, West Virginia, with a 330 KW PFBC plant. The purpose of the program was to demonstrate and verify PFBC in a full-scale commercial plant. The technical and cost baselines of the Cooperative Agreement were based on a preliminary engineering and design and a cost estimate developed by AEP subsequent to AEP's proposal submittal in May 1988, and prior to the signing of the Cooperative Agreement. The Statement of Work in the first budget period of the Cooperative Agreement included a task to develop a preliminary design and cost estimate for erecting a Greenfield plant and to conduct a comparison with the repowering option. The comparative assessment of the options concluded that erecting a Greenfield plant rather than repowering the existing Sporn Plant could be the technically and economically superior alternative. The Greenfield plant would have a capacity of 340 MW. The ten additional MW output is due to the ability to better match the steam cycle to the PFBC system with a new balance of plant design. In addition to this study, the conceptual design of the Sporn Repowering led to several items which warranted optimization studies with the goal to develop a more cost effective design.
Integrating Nuclear Energy to Oilfield Operations Two Case Studies
Fossil fuel resources that require large energy inputs for extraction, such as the Canadian oil sands and the Green River oil shale resource in the western USA, could benefit from the use of nuclear power instead of power generated by natural gas combustion. This paper discusses the technical and economic aspects of integrating nuclear energy with oil sands operations and the development of oil shale resources. A high temperature gas reactor (HTGR) that produces heat in the form of high pressure steam (no electricity production) was selected as the nuclear power source for both fossil fuel resources. Both cases were based on 50,000 bbl/day output. The oil sands case was a steam-assisted, gravity-drainage (SAGD) operation located in the Canadian oil sands belt. The oil shale development was an in-situ oil shale retorting operation located in western Colorado, USA. The technical feasibility of the integrating nuclear power was assessed. The economic feasibility of each case was evaluated using a discounted cash flow, rate of return analysis. Integrating an HTGR to both the SAGD oil sands operation and the oil shale development was found to be technically feasible for both cases. In the oil sands case, integrating an HTGR eliminated natural gas combustion and associated CO2 emissions, although there were still some emissions associated with imported electrical power. In the in situ oil shale case, integrating an HTGR reduced CO2 emissions by 88% and increased natural gas production by 100%. Economic viabilities of both nuclear integrated cases were poorer than the non-nuclear-integrated cases when CO2 emissions were not taxed. However, taxing the CO2 emissions had a significant effect on the economics of the non-nuclear base cases, bringing them in line with the economics of the nuclear-integrated cases. As we move toward limiting CO2 emissions, integrating non-CO2-emitting energy sources to the development of energy-intense fossil fuel resources is becoming increasingly important. This paper attempts to reduce the barriers that have traditionally separated fossil fuel development and application of nuclear power and to promote serious discussion of ideas about hybrid energy systems.

LIMB Demonstration Project Extension and Coolside Demonstration
This report presents results from the limestone Injection Multistage Burner (LIMB) Demonstration Project Extension. LIMB is a furnace sorbent injection technology designed for the reduction of sulfur dioxide (SO[sub 2]) and nitrogen oxides (NO[sub x]) emissions from coal-fired utility boilers. The testing was conducted on the 105 Mwe, coal-fired, Unit 4 boiler at Ohio Edison's Edgewater Station in Lorain, Ohio. In addition to the LIMB Extension activities, the overall project included demonstration of the Coolside process for S0[sub 2] removal for which a separate report has been issued. The primary purpose of the DOE LIMB Extension testing, was to demonstrate the generic applicability of LIMB technology. The program sought to characterize the S0[sub 2] emissions that result when various calcium-based sorbents are injected into the furnace, while burning coals having sulfur content ranging from 1.6 to 3.8 weight percent. The four sorbents used included calcitic limestone, dolomitic hydrated lime, calcitic hydrated lime, and calcitic hydrated lime with a small amount of added calcium lignosulfonate. The results include those obtained for the various coal/sorbent combinations and the effects of the LIMB process on boiler and plant operations.

Engineering study of a 20 MW lead--acid battery energy storage demonstration plant. Final report for the period ending October 1976
The Research and Engineering Operation of Bechtel Corporation conducted an engineering study of a 20-MW lead--acid battery energy storage demonstration plant. Ten alternative designs were evaluated. Basically, the configurations proposed for the demonstration plants are those of the mature plants which would follow. The designs of the individual plants are based on the cell designs and the means used to house the cells. Initially, proposed cell designs from five manufacturers were considered. To conform with the level of effort allowed for this engineering study, two manufacturers' cells (one open-tank design and one sealed cell design) were selected by ERDA and Bechtel as being representative. These designs formed the basis for the detailed evaluation conducted in this study. The plant and battery configurations evaluated in the study are a large open-tank cell, configured in rows and housed in four buildings; a sealed cell, configured in a single layer of close packed rows in a single building; a sealed cell, configured in a three-tiered arrangement in a single building; and a sealed cell, configured with groups of cells housed in weatherproof modules and placed outdoors. Annual operating costs based on these mature plant costs show lead--acid load-leveling plants are generally not economically competitive with the alternatives when no consideration is given to their other possible benefits to the power system. However, application of credits (e.g., transmission line or spinning reserve credits) can make such plants economically competitive with gas turbine peaking units in specific situations. 46 figures, 25 tables.

Electric Demand Cost Versus Labor Cost: A Case Study
Electric Utility companies charge industrial clients for two things: demand and usage. Depending on type of business and hours operation, demand cost could be very high. Most of the operations scheduling in a plant is achieved considering labor cost. For small plants, it is quite possible that a decrease in labor could result in an increase in electric demand and cost or vice versa. In this paper two cases are presented which highlight the dependence of one on other.

Fuel Cell Demonstration Program
In an effort to promote clean energy projects and aid in the commercialization of new fuel cell technologies the Long Island Power Authority (LIPA) initiated a Fuel Cell Demonstration Program in 1999 with six month deployments of Proton Exchange Membrane (PEM) non-commercial Beta model systems at partnering sites throughout Long Island. These projects facilitated significant developments in the technology, providing operating experience that allowed the manufacturer to produce fuel cells that were half the size of the Beta units and suitable for outdoor installations. In 2001, LIPA embarked on a large-scale effort to identify and develop measures that could improve the reliability and performance of future fuel cell technologies for electric utility applications and the concept to establish a fuel cell farm (Farm) of 75 units was developed. By the end of October of 2001, 75 Lorax 2.0 fuel cells had been installed at the West Babylon substation on Long Island, making it the first fuel cell demonstration of its kind and size anywhere in the world at the time. Designed to help LIPA study the feasibility of using fuel cells to operate in parallel with LIPA's electric grid system, the Farm operated 120 fuel cells over its lifetime of over 3 years including 3 generations of Plug Power fuel cells (Lorax 2.0, Lorax 3.0, Lorax 4.5). Of these 120 fuel cells, 20 Lorax 3.0 units operated under this Award from June 2002 to September 2004. In parallel with the operation of the Farm, LIPA recruited government and commercial/industrial customers to demonstrate fuel cells as on-site distributed generation. From December 2002 to February 2005, 17 fuel cells were tested and monitored at various customer sites throughout Long Island. The 37 fuel cells operated under this Award produced a total of 712,635 kWh. As fuel cell technology became more mature, performance improvements included a 1% increase in system efficiency. Including equipment, design, fuel, maintenance, installation, and decommissioning the total project budget was approximately $3.7 million.

Retrofit of Existing Residential Building: a Case Study
There are about 42 billion square meters of existing buildings in China. The energy efficiency of existing buildings directly relates to the energy consumption of the building sector. The retrofit of existing residential building began in the 1990s in Heilongjiang. The Sino-Canada demonstration project and Sino-France demonstration project of retrofitting existing residential buildings were carried out in 1997 and 2004, respectively. The retrofit method and energy conservation potential of the envelope and heating system of northern existing buildings are analyzed in this paper, combining the experiences of retrofitting existing residential buildings in Heilongjiang. The software was compiled to aid the design of the envelope retrofit in Heilongjiang and to analyze the working situation in existing residential building heating systems. The imbalance of the indoor temperature and the quantity of heating loss from opening the window in different retrofit projects are presented. The emphasis on energy efficiency retrofit of the envelope of existing residential buildings should be placed on the wall in northern region. It is possible to reduce about 50 percent of energy consumption of buildings by insulating the wall. The external insulation is suitable for retrofitting existing buildings, and the moisture transfer should be considered at the same time. To insure actual reduction in energy consumption, the heating system should be retrofitted when the envelope is insulated.

Case studies of energy information systems and related technology: Operational practices, costs, and benefits
Energy Information Systems (EIS), which can monitor and analyze building energy consumption and related data throughout the Internet, have been increasing in use over the last decade. Though EIS developers describe the capabilities, costs, and benefits of EIS, many of these descriptions are idealized and often insufficient for potential users to evaluate cost, benefit and operational usefulness. LBNL has conducted a series of case studies of existing EIS and related technology installations. This study explored the following questions: (1) How is the EIS used in day-to-day operation? (2) What are the costs and benefits of an EIS? (3) Where do the energy savings come from? This paper reviews the process of these technologies from installation through energy management practice. The study is based on interviews with operators and energy managers who use EIS. Analysis of energy data trended by EIS and utility bills was also conducted to measure the benefit. This paper explores common uses and findings to identify energy savings attributable to EIS, and discusses non-energy benefits as well. This paper also addresses technologies related to EIS that have been demonstrated and evaluated by LBNL.

A Case Study in Porting Strategy: The Axisymmetric Damage Model
The axisymmetric damage model (ADM) is one of four micromechanical stress field models developed and maintained by N. J. Pagano's group at the AFRL Materials Directorate, Wright-Patterson AFB. These models serve to establish rigorous field theories to compute accurate stresses and energy release rates for fracture mechanics problems in composite bodies. In turn, these solutions, coupled with experimental research, can establish appropriate failure criteria to be used in the design of composite structures for air and space vehicles. Each of these models is based on Reissner's variational theorem (Reissner, 1950). ADM (Pagano, 1991) is associated with axisymmetric cracking and boundary conditions. Others support fundamentally different cases, i.e. axisymmetric problems incorporating the effects of friction (Tandon and Pagano, 1996), transverse and shear loading and associated cracking patterns in composite cylinders (Pagano and Tandon, 1994), and transverse cracking and delamination pro...

Assimilation Key to Successful Implementation of Statewide Case Management Systems: Arizona Case Study
It is always a precarious situation to put oneself when attempting to acknowledge all those who have been instrumental and in support of ones effort to complete a program of this magnitude. Certainly I must recognize my managers that gave me opportunity to attend class when the demands of work were not always conducive to doing so. Tom Brady, Tempe Municipal Court Manager, and Rick Rager, Deputy Court Manager, were my supervisors at the beginning of this process, allowed me the time for class and encouraged me to attend. Lourraine Arkfeild, Presiding Judge for Tempe Municipal Court, has been a constant source of support while I was working at Tempe, and has continued to be such since I continued my career at the AOC. The opportunity to continue the program after beginning employment at the AOC was afforded me by Janet Scheiderer, Director of Court Services. I would also need to thank the AOC for funding my participation in the program. Additionally, throughout this process I have received input and words of support from so many in the Arizona courts system that I cannot begin to list them all. It is important to note the understanding, encouragement and practical input from my current manager, Renny Rapier, Program Manager for the General Jurisdiction Case Management System Project of which I am the Project Manager.

Regional biomass supply: three case studies in the Midwest, US
Increased interest in the development and utilization of alternative energy sources has generated research demonstrating that fuels developed from energy crops (biofuels) can be a viable substitute for fossil fuels. A national energy program dedicated to the advancement of fuel derived from lignocellulosic crops could have major impacts on conventional energy supplied in the United States. Sufficient biofuel demand would allow conversion of croplands, as well as some pasture and forest lands, into biomass producing lands and possibly return to production acres formerly idled. A shift from crop, pasture or forest production activities to biomass production would likely require changes in the levels of inputs, outputs, and costs associated with these activities, which would impact producers and ultimately consumers. The conversion of cropland or idled land to biomass production will also have impacts on the physical characteristics of the soil. Soil erosion levels, soil chemical composition, soil structure, and organic matter content are some of the many soil attributes which will be impacted as a result of conversion. Research is needed to estimate the impact conversion activities have on these variables.

Case Study- Steam System Improvements at Dupont Automotive Marshall Laboratory
Dupont's Marshall Laboratory is an automotive paint research and development facility in Philadelphia, Pennsylvania. The campus is comprised of several buildings that are served by Trigen-Philadelphia Energy Corporation's district steam loop. In 1996 Dupont management announced that it was considering moving the facility out of Philadelphia primarily due to the high operating cost compared to where they were considering relocating. The city officials responded by bringing the local electric and gas utilities to the table to negotiate better rates for Dupont. Trigen also requested the opportunity to propose energy savings opportunities, and dedicated a team of engineers to review Dupont's steam system to determine if energy savings could be realized within the steam system infrastructure. As part of a proposal to help Dupont reduce energy costs while continuing to use Trigen's steam, Trigen recommended modifications to increase energy efficiency, reduce steam system maintenance costs and implement small scale cogeneration. These recommendations included reducing the medium pressure steam distribution to low pressure, eliminating the medium pressure to low pressure reducing stations, installing a back pressure steam turbine generator, and preheating the domestic hot water with the condensate. Dupont engineers evaluated these recommended modifications and chose to implement most of them. An analysis of Dupont's past steam consumption revealed that the steam distribution system sizing was acceptable if the steam pressure was reduced from medium to low. After a test of the system and a few modifications, Dupont reduced the steam distribution system to low pressure. Energy efficiency is improved since the heat transfer losses at the low pressure are less than at the medium pressure distribution. Additionally, steam system maintenance will be significantly reduced since 12 pressure reducing stations are eliminated. With the steam pressure reduction now occurring at one location, the opportunity existed to install a backpressure turbine generator adjacent to the primary pressure reducing station. The analysis of Dupont's steam and electric load profiles demonstrated that cost savings could be realized with the installation of 150 kW of self-generation. There were a few obstacles, including meeting the utility's parallel operation requirements, that made this installation challenging. Over two years have passed since the modifications were implemented, and although cost savings are difficult to quantify since process steam use has increased, the comparison of steam consumption to heating degree days shows a reducing trend. Dupont's willingness to tackle energy conservation projects without adversely affecting their process conditions can be an example to other industrial steam users.

Technology commercialization cost model and component case study. Final report
Fuel cells seem poised to emerge as a clean, efficient, and cost competitive source of fossil fuel based electric power and thermal energy. Sponsors of fuel cell technology development need to determine the validity and the attractiveness of a technology to the market in terms of meeting requirements and providing value which exceeds the total cost of ownership. Sponsors of fuel cell development have addressed this issue by requiring the developers to prepare projections of the future production cost of their fuel cells in commercial quantities. These projected costs, together with performance and life projections, provide a preliminary measure of the total value and cost of the product to the customer. Booz-Allen & Hamilton Inc. and Michael A. Cobb & Company have been retained in several assignments over the years to audit these cost projections. The audits have gone well beyond a simple review of the numbers. They have probed the underlying technical and financial assumptions, the sources of data on material and equipment costs, and explored issues such as the realistic manufacturing yields which can be expected in various processes. Based on the experience gained from these audits, the DOE gave Booz-Allen and Michael A. Cobb & company the task to develop a criteria to be used in the execution of future fuel cell manufacturing cost studies. It was thought that such a criteria would make it easier to execute such studies in the future as well as to cause such studies to be more understandable and comparable.

TRUEX hot demonstration
In FY 1987, a program was initiated to demonstrate technology for recovering transuranic (TRU) elements from defense wastes. This hot demonstration was to be carried out with solution from the dissolution of irradiated fuels. This recovery would be accomplished with both PUREX and TRUEX solvent extraction processes. Work planned for this program included preparation of a shielded-cell facility for the receipt and storage of spent fuel from commercial power reactors, dissolution of this fuel, operation of a PUREX process to produce specific feeds for the TRUEX process, operation of a TRUEX process to remove residual actinide elements from PUREX process raffinates, and processing and disposal of waste and product streams. This report documents the work completed in planning and starting up this program. It is meant to serve as a guide for anyone planning similar demonstrations of TRUEX or other solvent extraction processing in a shielded-cell facility.

International ESCO business opportunities and challenges: a Japanese case study
Recently, US energy service companies (ESCOs) have begun to actively explore markets outside the US. Despite the needs of many countries for ESCO involvement, ESCOs face many challenges (i.e., marketing, financial, institutional, political and cultural barriers). Consequently, most of these firms pursue international project opportunities very selectively due to the costs and risks associated with project development. Despite these barriers, some ESCOs view international work as a strategic expansion of their business, assuming that there will be adequate business in the future to repay them for their initial investment. In this paper, the authors present the findings from a recently completed study on the proposed development of an ESCO industry in Japan. The study was based on four sources of information: (1) a review of the published and unpublished literature on ESCOs; (2) interviews with 26 ESCOs in the US, the US Department of Energy, and the National Association of Energy Service Companies (NAESCO); (3) ESCO presentations at the October 1996 NAESCO meeting; and (4) informal discussions with ESCO experts in the US. They believe that the lessons learned in this study can be transferred or applied to other countries interested in developing an ESCO industry. While energy prices have remained relatively stable over the last several years in Japan and energy capacity is not perceived as a near-term problem, other ``market drivers`` necessary for the emergence of a successful and vibrant ESCO industry exist in Japan. Despite the presence of these market drivers, significant barriers to the successful development of an ESCO industry exist in Japan.

Clean Cities Case Study: UPS delivers with Alternative Fuels
In the fall of 1994, the UPS fleet in Landover, Maryland, began operating 20 vehicles on CNG. UPS selected CNG because natural gas is an abundant domestic resource that is available in almost every city in the US, and it also generally costs less than other fuels. The UPS project, funded by DOE through NREL and managed by TRI, was designed to test the feasibility of using CNG in a medium-duty pick-up and delivery fleet. This study is intended only to illustrate approaches that organizations could use in adopting AFVs into their fleets.

Modelling Chinese Smart Grid: A Stochastic Model Checking Case Study
Cyber-physical systems integrate information and communication technology functions to the physical elements of a system for monitoring and controlling purposes. The conversion of traditional power grid into a smart grid, a fundamental example of a cyber-physical system, raises a number of issues that require novel methods and applications. In this context, an important issue is the verification of certain quantitative properties of the system. In this technical report, we consider a specific Chinese Smart Grid implementation and try to address the verification problem for certain quantitative properties including performance and battery consumption. We employ stochastic model checking approach and present our modelling and analysis study using PRISM model checker.

Hairpin vortex formation, a case study for unsteady visualization.
To better understand the vortex dynamics of coherent structures in turbulent and transitional boundary layers, we consider direct numerical simulation of the interaction between a flat-plateboundary-layer flow and an isolated hemispherical roughness element. Of principal interest is the evolution of hairpin vortices that form an interlacing pattern in the wake of the hemisphere, lift away from the wall, and are stretched by the shearing action of the boundary layer. Using animations of unsteady three-dimensional representations of this flow, produced by the vtk toolkit and enhanced to operate in a CAVE virtual environment, we identify and study several key features in the evolution of this complex vortex topology not previously observed in other visualization formats.

Case Studies of Industrial Cogeneration in the U. S.
This paper describes the results of a survey and evaluation of plant-specific information on industrial cogeneration. The study was performed as part of a project sponsored by the Electric Power Research Institute to evaluate Dual Energy Use Systems (DEUS). The purpose of this project was to evaluate site specific data on DEUS from the utility perspective, identify promising candidates, and define R&D opportunities. The first major task in this DEUS project was a survey of industrial cogeneration sites to identify the technoeconomic and institutional factors affecting the success of cogeneration systems in industry. Sites were selected based on a mix of industry types, geographic location, type of cogeneration system, generating capacity, age of plant and other characteristics. Site-specific surveys were conducted and supplemented by information from secondary sources such as FERC and DOE statistical data systems. This paper presents information on 17 cogeneration facilities. Also presented is information on the perspectives of the relevant utilities.

Global Simulation of Bioenergy Crop Productivity: Analytical framework and Case Study for Switchgrass
Contemporary global assessments of the deployment potential and sustainability aspects of biofuel crops lack quantitative details. This paper describes an analytical framework capable of meeting the challenges associated with global scale agro-ecosystem modeling. We designed a modeling platform for bioenergy crops, consisting of five major components: (i) standardized global natural resources and management data sets, (ii) global simulation unit and management scenarios, (iii) model calibration and validation, (iv) high-performance computing (HPC) modeling, and (v) simulation output processing and analysis. A case study with the HPC- Environmental Policy Integrated Climate model (HPC-EPIC) to simulate a perennial bioenergy crop, switchgrass (Panicum virgatum L.) and global biomass feedstock analysis on grassland demonstrates the application of this platform. The results illustrate biomass feedstock variability of switchgrass and provide insights on how the modeling platform can be expanded to better assess sustainable production criteria and other biomass crops. Feedstock potentials on global grasslands and within different countries are also shown. Future efforts involve developing databases of productivity, implementing global simulations for other bioenergy crops (e.g. miscanthus, energycane and agave), and assessing environmental impacts under various management regimes. We anticipated this platform will provide an exemplary tool and assessment data for international communities to conduct global analysis of biofuel biomass feedstocks and sustainability.

Energy Economizer for Low Temperature Stack Gas: A Case Study
Bartlesville (Oklahoma) Energy Technology Center (BETC) engineers made a study of recycling waste heat from one of the Power Plant boilers. The study showed that a system could be designed that would reclaim this waste heat and then utilize it to preheat air for boiler operation. The system incorporated a heat pipe heat exchanger flanged in a stack by-pass loop that would efficiently capture and transfer heat at low temperature differences (?T 350-5000 F). After reclaiming heat from this source, the burner air supply is preheated by passing through the heat exchanger. Sensitive design problems that had to be resolved were: Overall cost-effectiveness; below dew point cooling of stack gas causing acid corrosion; and selection of an effective heat exchanger for this application The candidate boiler is one of two that generate high temperature hot water (HTHW) for BETC facility heating and cooling. One unit normally handles the heating and cooling load while the other is in standby status. The preheat system was designed by BETC engineers. The new stack assembly was fabricated by a local metal shop, and was installed by BETC maintenance personnel. The cost of the heat exchanger and other hard-ware was $7,562. Operational results show that boiler efficiency has increased between 6 and 7 percent, which reflects the percent of reduction in fuel consumption. At full-load conditions, the burner supply air is preheated to 350oF and stack gas is cooled to 310oF. Corrosion damage to the heat exchanger and other internal parts are non-existent. Natural gas is the boiler fuel, and as expected, no residue coating of the heat exchanger has developed. To date, we are well pleased with the performance of the system. The savings in fuel and dollars speaks for itself. We are optimistic that this approach of reclaiming heat is not only technically feasible, but also cost-effective for many industry boilers that emit low temperature stack gas.

A Residential Duct Leakage Case Study on 'Good Cents' Homes
The Good Cents program has been adopted by many cities across the United States and has encouraged builders to employ aggressive energy conservation building techniques in residential applications. The program is well established and has been recognized for the added value it brings to homeowners. The primary energy using system in a residence is the heating and cooling system and in the hot and humid Southeast Texas climate, cooling is the predominant mode of operation for the HVAC system. This makes the system particularly susceptible to degraded performance if there are leaks in the air distribution system. Nine Good Cents homes in the College Station, Texas area were chosen for a study to determine the extent of HVAC air distribution leakage in the HVAC system. It was found that all the homes had significant measured leakage for the return-air side of the system. Houses with vertical sheet-rock lined plenums had significantly higher rates of return air leakage than homes with ducted returns.

Solar energy system case study: Telex Communications, Blue Earth, Minnesota
A study is made of a solar energy system for space heating a 97,000-square-foot office, factory, and warehouse building owned by Telex Communications, Inc. in Blue Earth, Minnesota. The solar system has 11,520 square feet of ground-oriented flat-plate collectors and a 20,000-gallon storage tank inside the building. Freeze protection is by drainback. Solar heated water from the storage tank circulates around the clock throughout the heating season to heating coils in the ducts. The system achieves its design solar fraction, is efficient, and generally reliable, but not cost-effective. Performance data for the solar system was collected by the National Solar Data Network for three heating seasons from 1978 to 1981. Because of a freeze-up of the collector array in December 1978, the solar system was only partially operational in the 1978 to 1979 heating season. The data in this report were collected in the 1979 to 1980 and 1980 to 1981 heating seasons.

Sealtest Ice Cream: A Case Study in Cooperation
This was the first large industrial program from a Northeast utility. By participating in the DSM program, Sealtest completed a $3.5 million energy efficiency project. The efficiency improvements cut energy costs by over $425,000 per year and cut its electricity bills by one-third. The project is saving enough electricity to light one thousand homes. The project began with an energy efficiency study that identified opportunities for improved energy efficiency primarily through major changes in the facility's refrigeration equipment. Estimates of potential savings were based on profiles generated of baseline and post-retrofit electric consumption. These profiles required knowledge of the operation of the facility and expertise in design and operation of state-of-the-art refrigeration systems for this kind of industrial facility. A monitoring system was installed to verify the baseline profiles and to measure post-retrofit consumption. Time constraints dictated by construction schedules necessitated substantial effort to obtain all of the seasonal load shapes required to run the screening models. With cooperative effort between the Owner, Utility, contractors and engineers, the project was completed on time, and monitored savings exceeded expectations.

Hospital waste management and toxicity evaluation: A case study
Hospital waste management is an imperative environmental and public safety issue, due to the waste's infectious and hazardous character. This paper examines the existing waste strategy of a typical hospital in Greece with a bed capacity of 400-600. The segregation, collection, packaging, storage, transportation and disposal of waste were monitored and the observed problematic areas documented. The concentrations of BOD, COD and heavy metals were measured in the wastewater the hospital generated. The wastewater's toxicity was also investigated. During the study, omissions and negligence were observed at every stage of the waste management system, particularly with regard to the treatment of infectious waste. Inappropriate collection and transportation procedures for infectious waste, which jeopardized the safety of staff and patients, were recorded. However, inappropriate segregation practices were the dominant problem, which led to increased quantities of generated infectious waste and hence higher costs for their disposal. Infectious waste production was estimated using two different methods: one by weighing the incinerated waste (880 kg day{sup -1}) and the other by estimating the number of waste bags produced each day (650 kg day{sup -1}). Furthermore, measurements of the EC{sub 50} parameter in wastewater samples revealed an increased toxicity in all samples. In addition, hazardous organic compounds were detected in wastewater samples using a gas chromatograph/mass spectrograph. Proposals recommending the application of a comprehensive hospital waste management system are presented that will ensure that any potential risks hospital wastes pose to public health and to the environment are minimized.

Hierarchical Models for Batteries: Overview with Some Case Studies
Batteries are complex multiscale systems and a hierarchy of models has been employed to study different aspects of batteries at different resolutions. For the electrochemistry and charge transport, the models span from electric circuits, single-particle, pseudo 2D, detailed 3D, and microstructure resolved at the continuum scales and various techniques such as molecular dynamics and density functional theory to resolve the atomistic structure. Similar analogies exist for the thermal, mechanical, and electrical aspects of the batteries. We have been recently working on the development of a unified formulation for the continuum scales across the electrode-electrolyte-electrode system - using a rigorous volume averaging approach typical of multiphase formulation. This formulation accounts for any spatio-temporal variation of the different properties such as electrode/void volume fractions and anisotropic conductivities. In this talk the following will be presented: The background and the hierarchy of models that need to be integrated into a battery modeling framework to carry out predictive simulations, Our recent work on the unified 3D formulation addressing the missing links in the multiscale description of the batteries, Our work on microstructure resolved simulations for diffusion processes, Upscaling of quantities of interest to construct closures for the 3D continuum description, Sample results for a standard Carbon/Spinel cell will be presented and compared to experimental data, Finally, the infrastructure we are building to bring together components with different physics operating at different resolution will be presented. The presentation will also include details about how this generalized approach can be applied to other electrochemical storage systems such as supercapacitors, Li-Air batteries, and Lithium batteries with 3D architectures.

Estimating recharge at Yucca Mountain, Nevada: A case study
Obtaining values of net infiltration, groundwater travel time, and recharge is necessary at the Yucca Mountain site, Nevada, USA, in order to evaluate the expected performance of a potential repository as a containment system for high-level radioactive waste. However, the geologic complexities of this site, its low precipitation and net infiltration, with numerous mechanisms operating simultaneously to move water through the system, provide many challenges for the estimation of the spatial distribution of recharge. A variety of methods appropriate for arid environments has been applied, including water-balance techniques, calculations using Darcy's law in the unsaturated zone, a soil-physics method applied to neutron-hole water-content data, inverse modeling of thermal profiles in boreholes extending through the thick unsaturated zone, chloride mass balance, atmospheric radionuclides, and empirical approaches. These methods indicate that near-surface infiltration rates at Yucca Mountain are highly variable in time and space, with local (point) values ranging from zero to several hundred millimeters per year. Spatially distributed net-infiltration values average 5 mm/year, with the highest values approaching 20 mm/year near Yucca Crest. Site-scale recharge estimates range from less than 1 to about 12 mm/year. These results have been incorporated into a site-scale model that has been calibrated using these data sets that reflect infiltration processes acting on highly variable temporal and spatial scales. The modeling study predicts highly non-uniform recharge at the water table, distributed significantly differently from the non-uniform infiltration pattern at the surface.

LIMB Demonstration Project Extension
The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO{sub x} and NO{sub x} emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintained at levels existing prior to LIMB retrofit, and (c) technical difficulties attributable to LIMB operation, such as additional slagging and fouling, changes in ash disposal requirements, and an increased particulate load, can be resolved in a cost-effective manner. The primary fuel to be used will be an Ohio bituminous coal having a nominal sulfur content of 3 percent or greater.

AVNG system demonstration
An attribute measurement system (AMS) measures a number of unclassified attributes of potentially classified material. By only displaying these unclassified results as red or green lights, the AMS protects potentially classified information while still generating confidence in the measurement result. The AVNG implementation that we describe is an AMS built by RFNC - VNIIEF in Sarov, Russia. To provide additional confidence, the AVNG was designed with two modes of operation. In the secure mode, potentially classified measurements can be made with only the simple red light/green light display. In the open mode, known unclassified material can be measured with complete display of the information collected from the radiation detectors. The AVNG demonstration, which occurred in Sarov, Russia in June 2009 for a joint US/Russian audience, included exercising both modes of AVNG operation using a number of multi-kg plutonium sources. In addition to describing the demonstration, we will show photographs and/or video taken of AVNG operation.

Automatic lighting controls demonstration
The purpose of this work was to demonstrate, in a real building situation, the energy and peak demand reduction capabilities of an electronically ballasted lighting control system that can utilize all types of control strategies to efficiently manage lighting. The project has demonstrated that a state-of-the-art electronically ballasted dimmable lighting system can reduce energy and lighting demand by as least 50% using various combinations of control strategies. By reducing light levels over circulation areas (tuning) and reducing after hours light levels to accommodate the less stringent lighting demands of the cleaning crew (scheduling), lighting energy consumption on weekdays was reduced an average of 54% relative to the initial condition. 10 refs., 14 figs., 3 tabs.

Benefits from flywheel energy storage for area regulation in California - demonstration results : a study for the DOE Energy Storage Systems program.
This report documents a high-level analysis of the benefit and cost for flywheel energy storage used to provide area regulation for the electricity supply and transmission system in California. Area regulation is an 'ancillary service' needed for a reliable and stable regional electricity grid. The analysis was based on results from a demonstration, in California, of flywheel energy storage developed by Beacon Power Corporation (the system's manufacturer). Demonstrated was flywheel storage systems ability to provide 'rapid-response' regulation. Flywheel storage output can be varied much more rapidly than the output from conventional regulation sources, making flywheels more attractive than conventional regulation resources. The performance of the flywheel storage system demonstrated was generally consistent with requirements for a possible new class of regulation resources - 'rapid-response' energy-storage-based regulation - in California. In short, it was demonstrated that Beacon Power Corporation's flywheel system follows a rapidly changing control signal (the ACE, which changes every four seconds). Based on the results and on expected plant cost and performance, the Beacon Power flywheel storage system has a good chance of being a financially viable regulation resource. Results indicate a benefit/cost ratio of 1.5 to 1.8 using what may be somewhat conservative assumptions. A benefit/cost ratio of one indicates that, based on the financial assumptions used, the investment's financial returns just meet the investors target.

LASSIE: Libraries and Social Software in Education Case Study 5:Libraries and Facebook
Page 1This case study explores the use of the social networking site Facebook (www.facebook.com) as a tool for libraries and librarians. The case study was launched some way into the project following the growth and popularity of this social networking site. Many librarians have now joined Facebook for purely social reasons, however it can overlap into the professional world as it is being used by several professional library groups and for promoting library related events. Facebook also has a number of library related tools which the project team felt were worthy of further exploration. This case study is slightly different to the four other case studies, because we did not set up a specific library-related initiative in Facebook for use with librarians or distance learners. The case study is largely based on the literature and our own experiences of using Facebook. The reasons for this approach were twofold: partly because the use of Facebook accelerated phenomenally during the period when we were undertaking our research (March 2007 January 2008). Early on in the project and at the time of planning the case studies we could not have anticipated the level of interest that developed in this social networking site. This was specifically a UK-based phenomena and largely driven by the extensive coverage that the site received in the mainstream media during the summer of 2007. It also did not seem appropriate to set up a project-related initiative in Facebook for real

Santa Clara Demonstration Status
Fuel Cell Engineering Corporation (FCE) is in the fourth year of a DOE Cooperative Agreement Program (private-sector cost-shared) aimed at the demonstration of ERC's direct carbonate fuel cell (DFC) technology at full scale. FCE is a wholly owned subsidiary of Energy Research Corporation (ERC), which has been pursuing the development of the DFC for commercialization near the end of this decade. The DFC produces power directly from hydrocarbon fuels electrochemically, without the need for external reforming or intermediate mechanical conversion steps. As a result, the DFC has the potential to achieve very high efficiency with very low levels of environmental emissions. Modular DFC power plants, which can be shop-fabricated and sited near the user, are ideally suited for distributed generation, cogeneration, industrial, and defense applications. This project is an integral part of the ERC effort to commercialize the technology to serve these applications. Potential users of the commercial DFC power plant under development at ERC will require that the technology be demonstrated at or near the full scale of the commercial products. The objective of the Santa Clara Demonstration Project (SCDP) is to provide the first such demonstration of the technology. The approach ERC has taken in the commercialization of the DFC is described in detail elsewhere [1]. Briefly, an aggressive core technology development program is in place which is focused by ongoing contact with customers and vendors to optimize the design of the commercial power plant. ERC has selected a 2.85 MW power plant unit for initial market entry. Two ERC subsidiaries are supporting the commercialization effort: The Fuel Cell Manufacturing Corporation (FCMC) and the Fuel Cell Engineering Corporation (FCE). FCMC manufactures carbonate stacks and multi-stack modules, currently from its manufacturing facility in Torrington, CT. FCE is responsible for power plant design, integration of all subsystems, sales/marketing, and client services. The commercial product specifications have been developed by working closely with the Fuel Cell Commercialization Group (FCCG). FCCG members include municipal utilities, rural electric co-ops, and investor owned utilities who have expressed interest in being the initial purchasers of the first commercial DFC power plants. The utility participants in the SCDP have been drawn from the membership of FCCG. FCE is serving as the prime contractor for the design, construction, and testing of the SCDP Plant, and FCMC has manufactured the multi-stack submodules used in the DC power section of the plant. Fluor Daniel Inc. (FDI) served as the architect-engineer for the design and construction of the plant, and also provided support to the design of the multi-stack submodules. FDI is also assisting the ERC companies in commercial power plant design.

Jennings Demonstration PLant
Verenium operated a demonstration plant with a capacity to produce 1.4 million gallons of cellulosic ethanol from agricultural resiues for about two years. During this time, the plant was able to evaluate the technical issues in producing ethanol from three different cellulosic feedstocks, sugar cane bagasse, energy cane, and sorghum. The project was intended to develop a better understanding of the operating parameters that would inform a commercial sized operation. Issues related to feedstock variability, use of hydrolytic enzymes, and the viability of fermentative organisms were evaluated. Considerable success was achieved with pretreatment processes and use of enzymes but challenges were encountered with feedstock variability and fermentation systems. Limited amounts of cellulosic ethanol were produced.

Prioritization and Implementation Plan for Collaborative Case Study on RPV Steels During Extended Service
Nuclear power currently provides a significant fraction of the United States non-carbon emitting power generation. In future years, nuclear power must continue to generate a significant portion of the nation's electricity to meet the growing electricity demand, clean energy goals, and ensure energy independence. New reactors will be an essential part of the expansion of nuclear power. However, given limits on new builds imposed by economics and industrial capacity, the extended service of the existing fleet will also be required. Ensuring public safety and environmental protection is a prerequisite to all nuclear power plant operating and licensing decisions at all stages of reactor life. This includes the original license period of 40 years, the first license extension to 60 years, and certainly for any consideration of life beyond 60 years. For extended operating periods, it must be shown that adequate aging management programs are present or planned and that appropriate safety margins exist throughout the subsequent license renewal periods. Materials degradation can impact reactor reliability, availability, and potentially, safe operation. Components within a reactor must tolerate the harsh environment of high temperature water, stress, vibration, and/or an intense neutron field. Degradation of materials in this environment can lead to reduced performance, and in some cases, sudden failure. Clearly, understanding materials degradation and accounting for the effects of a reactor environment in operating and regulatory limits is essential. The Light Water Reactor Sustainability (LWRS) Program is designed to support the long-term operation (LTO) of existing domestic nuclear power generation with targeted collaborative research programs into areas beyond current short-term optimization opportunities. Within the LWRS program, two pathways have been initiated to perform research essential to informing relicensing decisions. The Materials Aging and Degradation Pathway is designed to help develop the scientific basis for understanding and predicting long-term environmental degradation behavior of materials in nuclear power plants and to provide data and methods to assess performance of systems, structures, and components essential to safe and sustained operation. The Risk-Informed Safety Margins Characterization Pathway (RISMC) seeks to merge fundamental scientific understanding of critical phenomenological conditions and deterministic predictions of nuclear power plant performance with risk-informed characterization tools. This will provide an integrated characterization of public safety margins in an optimization of nuclear safety, plant performance, and long-term asset management. Clearly, these two pathways have many synergies in goals and outcomes. The data and mechanisms generated in the Materials Pathway may feed into and mold efforts within the RISMC Pathway. In addition, insights from the characterization tools developed in RISMC tasks may inform materials testing needs and experiments. To demonstrate this potentially powerful interaction, a joint case study has been proposed and initiated. This document describes the initial planning for a coordinated study between the Materials and the RISMC Pathways. A brief description of each Pathway is presented along with a more detailed description of the needs and requirements of this collaborative task. A list of criteria for any case-study candidate are then listed, along with the rationale for choosing pressurized thermal shock as the prime candidate an inter-pathway collaboration. A proposed timeline and organization of future interactions on this subject area is also presented.

A study of toxic emissions from a coal-fired power plant utilizing an ESP while demonstrating the ICCT CT-121 FGD Project. Final report
The US Department of Energy is performing comprehensive assessments of toxic emissions from eight selected coal-fired electric utility units. This program responds to the Clean Air Act Amendments of 1990, which require the US Environmental Protection Agency (EPA) to evaluate emissions of hazardous air pollutants (HAPs) from electric utility power plants for Potential health risks. The resulting data will be furnished to EPA utility power plants and health risk determinations. The assessment of emissions involves the collection and analysis of samples from the major input, process, and output streams of each of the eight power plants for selected hazardous Pollutants identified in Title III of the Clean Air Act. Additional goals are to determine the removal efficiencies of pollution control subsystems for these selected pollutants and the Concentrations associated with the particulate fraction of the flue gas stream as a function of particle size. Material balances are being performed for selected pollutants around the entire power plant and several subsystems to identify the fate of hazardous substances in each utility system. Radian Corporation was selected to perform a toxics assessment at a plant demonstrating an Innovative Clean Coal Technology (ICCT) Project. The site selected is Plant Yates Unit No. 1 of Georgia Power Company, which includes a Chiyoda Thoroughbred-121 demonstration project.

Case Studies of Systems Integration through Energy Simulation During Early Design Phase
The paper presents two case studies, a commercial & a community project, in Houston Texas, where energy simulation and a decision matrix were used to solve budget conflicts and meet LEED EA-1 requirements. The first case study consists of the analysis of three different direct-expansion (DX) systems in an underfloor air distribution (UFAD) configuration for an office building with an unusually large footprint. Of the three options, only two could meet EA-1 pre-requisite for LEED-NC certification while meeting the project budget. The second case study involves analysis of a 120,000 sf. Community recreation center with multiple space types and operation schedules. The analysis employed different combinations of energy recovery systems, efficient lighting package, skylights and large efficient ceiling fans. While all the options met LEED-NC EA-1 prerequisite, each had a different payback time. Finally a combination of strategies was used for optimum payback and energy efficiency.

An approach to model validation and model-based prediction -- polyurethane foam case study.
Enhanced software methodology and improved computing hardware have advanced the state of simulation technology to a point where large physics-based codes can be a major contributor in many systems analyses. This shift toward the use of computational methods has brought with it new research challenges in a number of areas including characterization of uncertainty, model validation, and the analysis of computer output. It is these challenges that have motivated the work described in this report. Approaches to and methods for model validation and (model-based) prediction have been developed recently in the engineering, mathematics and statistical literatures. In this report we have provided a fairly detailed account of one approach to model validation and prediction applied to an analysis investigating thermal decomposition of polyurethane foam. A model simulates the evolution of the foam in a high temperature environment as it transforms from a solid to a gas phase. The available modeling and experimental results serve as data for a case study focusing our model validation and prediction developmental efforts on this specific thermal application. We discuss several elements of the ''philosophy'' behind the validation and prediction approach: (1) We view the validation process as an activity applying to the use of a specific computational model for a specific application. We do acknowledge, however, that an important part of the overall development of a computational simulation initiative is the feedback provided to model developers and analysts associated with the application. (2) We utilize information obtained for the calibration of model parameters to estimate the parameters and quantify uncertainty in the estimates. We rely, however, on validation data (or data from similar analyses) to measure the variability that contributes to the uncertainty in predictions for specific systems or units (unit-to-unit variability). (3) We perform statistical analyses and hypothesis tests as a part of the validation step to provide feedback to analysts and modelers. Decisions on how to proceed in making model-based predictions are made based on these analyses together with the application requirements. Updating modifying and understanding the boundaries associated with the model are also assisted through this feedback. (4) We include a ''model supplement term'' when model problems are indicated. This term provides a (bias) correction to the model so that it will better match the experimental results and more accurately account for uncertainty. Presumably, as the models continue to develop and are used for future applications, the causes for these apparent biases will be identified and the need for this supplementary modeling will diminish. (5) We use a response-modeling approach for our predictions that allows for general types of prediction and for assessment of prediction uncertainty. This approach is demonstrated through a case study supporting the assessment of a weapons response when subjected to a hydrocarbon fuel fire. The foam decomposition model provides an important element of the response of a weapon system in this abnormal thermal environment. Rigid foam is used to encapsulate critical components in the weapon system providing the needed mechanical support as well as thermal isolation. Because the foam begins to decompose at temperatures above 250 C, modeling the decomposition is critical to assessing a weapons response. In the validation analysis it is indicated that the model tends to ''exaggerate'' the effect of temperature changes when compared to the experimental results. The data, however, are too few and to restricted in terms of experimental design to make confident statements regarding modeling problems. For illustration, we assume these indications are correct and compensate for this apparent bias by constructing a model supplement term for use in the model-based predictions. Several hypothetical prediction problems are created and addressed. Hypothetical problems are used because no guidance was provided concern

Case-control study of cancer among Du Pont employees with potential for exposure to dimethylformamide
This case-control study was undertaken to determine whether the risk of developing cancers of the buccal cavity and pharynx (N = 39), liver (N = 6), prostate (N = 43), testis (N = 11), or malignant melanoma of the skin (N = 39) is related to exposure to dimethylformamide (DMF). Case and control subjects were obtained from four Du Pont plants. DMF is produced at one plant and used at the other three. Cancer cases identified from the company Cancer Registry comprise those reported among active male employees at the study plants during 1956 to 1985. For each case, two control subjects were selected, matched on sex, payroll class (wage or salary), birth year, and plant. To determine whether an employee could have been exposed to DMF during his career at the plant, all jobs with potential for exposure to DMF were identified. Each job was assigned an exposure ranking based on DMF industrial hygiene air monitoring, DMF metabolite (measured as N-methylformamide in urine) monitoring, and knowledge of the evolution of manufacturing processes and workplace exposure controls. Each employee's DMF exposure pattern was then characterized as (a) ever v never having been exposed to DMF and (b) highest DMF exposure experienced. Summary analyses for all plants combined showed no statistically significant association between ever having been exposed to DMF and subsequent development of cancers of the buccal cavity and pharynx, liver, malignant melanoma, prostate, and testis. Examined by plant site, prostate cancer at one plant was significantly elevated, based on three case subjects exposed out of four.

NanoInfoBio: A case-study in interdisciplinary research
A significant amount of high-impact contemporary scientific research occurs where biology, computer science, engineering and chemistry converge. Although programmes have been put in place to support such work, the complex dynamics of interdisciplinarity are still poorly understood. In this paper we highlight potential barriers to effective research across disciplines, and suggest, using a case study, possible mechanisms for removing these impediments.
