Countering the proliferation of nuclear weapons and other weapons of mass destruction (WMD) remains a U.S. national security priority. According to the 2017 National Security Strategy, terrorist groups continue to pursue WMD-related materials, which pose a grave danger to the United States. As also stated in the 2017 National Security Strategy, Russia’s nuclear arsenal remains the most existential threat to the United States, China’s nuclear arsenal is growing and diversifying, Iran has the potential of renewing its nuclear program and North Korea has pursued nuclear weapons despite international commitments. As the DSB report noted, U.S. monitoring abilities are increasingly challenged by evolving risks in 1) the capability of existing nuclear states and 2) the number of state and nonstate actors possessing or attempting to possess nuclear weapons. U.S. nonproliferation activities are conducted and coordinated across multiple government agencies and organizations, as well as the intelligence community. In addition, these efforts are coordinated with international entities, national laboratories, industry, and academia. U.S. nuclear nonproliferation verification and monitoring efforts are guided by, among other things, U.S. obligations under the Treaty on the Non- Proliferation of Nuclear Weapons (NPT) and U.S. support for the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO). The NPT lays out the respective responsibilities of nuclear-weapon and nonnuclear-weapon states with regard to the transfer, acquisition, possession, control, and manufacture of nuclear weapons. All nonnuclear-weapon states are required to have a comprehensive safeguards agreement with the International Atomic Energy Agency (IAEA) to facilitate IAEA’s safeguards activities. IAEA safeguards are a set of technical measures and activities by which IAEA seeks to verify that nuclear material subject to safeguards is not diverted to nuclear weapons or other proscribed purposes. Under the Comprehensive Nuclear Test-Ban Treaty (CTBT), which has yet to enter into force, parties agree not to carry out any nuclear explosions. The United States supports the work of the CTBTO to build up a verification regime in preparation for the treaty’s entry into force. The Administration’s fiscal year 2018 plan for verification and monitoring described ongoing interagency efforts to support nuclear proliferation verification and monitoring and includes information about relevant national priorities, capability gaps, R&D initiatives, and roles and responsibilities. The 2018 plan (40 pages) is longer and more detailed than the 2015 plan (2 pages) or the 2017 update (4 pages). The bulk of the 2018 plan is contained in two chapters—one chapter broadly describes U.S. and international efforts and roles and responsibilities, and the other chapter describes ongoing U.S. R&D efforts. We found the Administration’s 2018 plan provided details on each of the four major reporting requirements called for in the fiscal year 2018 NDAA with the exception of future costs and funding needs (see table 1). The first reporting requirement called for a plan and roadmap for verification, detection, and monitoring with respect to policy, operations, and research, development, testing, and evaluation, including— Identifying requirements for verification, detection, and monitoring; Identifying and integrating roles, responsibilities, and planning for verification, detection, and monitoring activities; and The costs and funding requirements over 10 years for these activities. We found that the 2018 plan provided detail on verification, detection, and monitoring requirements and roles and responsibilities, but did not provide details on future costs and funding needed to support the activities in the plan. We found that the plan identified requirements for verification, detection, and monitoring as required. To identify these requirements, the plan notes that interagency partners first identified a set of verification and monitoring priorities. From these priorities they identified a number of technical gaps. The plan then described dozens of examples of R&D efforts and non-technical activities to address those technical gaps. For example, for one gap the plan identifies eight current efforts to address this gap, including continued Department of Energy and NNSA investment in sensor capabilities that are small, light, and can operate in low power. We found that the plan provided details on the requirement to identify and integrate roles and responsibilities and planning. The plan includes details of the roles and responsibilities of interagency partners and international bodies that cooperate in the nonproliferation realm. For example, the plan describes how the Department of Defense is to support U.S. verification activities under the CTBT, including the installation, operation, and maintenance of U.S. International Monitoring Systems. We found that the plan did not identify costs and funding needs over a 10- year period. NNSA officials stated that they believed providing funding information over a 10-year period is unrealistic for several reasons. First, according to NNSA officials, it is not feasible to achieve agreement on actual or implied budgets outside of the existing President’s budget process. Second, according to NNSA officials, agencies have little influence over the funding priorities of other departments outside of existing budget efforts. Third, according to NNSA officials, long-term funding estimates are infeasible because the President’s budget only identifies funding levels five years into the future. However, the 2018 NDAA did not ask for budget information. Instead, the NDAA reporting requirement called for long-term costs and funding information necessary to support the verification and monitoring activities in the plan. Finally, NNSA officials told us that they and officials from other agencies briefed the appropriate congressional committees prior to the release of the 2018 plan, and discussed the challenges with providing cost and funding data. According to NNSA officials, they verified with the congressional committees that providing such information in the plan would be impractical. We have previously reported that providing estimates of future costs and funding needs can help congressional decisionmakers prioritize projects and identify long-term funding needs. NNSA as well as other agencies within the federal government already develop plans with long-term funding priorities and cost estimates. For example, in June 2014, we reported on 10-year estimates for sustaining and modernizing U.S. nuclear weapons capabilities. As we found in this and other reports, even when budgets are preliminary or not yet known, plans that include a range of potential estimates help Congress prioritize projects and funding. Because the plan does not include any information on interagency costs and funding needs, it limits 1) congressional understanding of the long-term affordability of the nation’s verification and monitoring efforts and 2) Congress’s ability to make necessary funding and policy decisions. By including in its plan estimates of future costs and funding needed to support the activities in the plan, NNSA could help provide assurance that agencies are allocating appropriate resources to the verification and monitoring effort. In addition, including estimates of future costs and funding needs in the plan can help ensure that interagency partners understand the amount of resources necessary to support verification and monitoring efforts, and determine if these resources align with agency activities. We have previously reported on the importance of identifying resources among collaborating agencies; we noted that without information on resource contributions from partners in a collaborative effort, there is less assurance that agency contributions are appropriate to successfully sustain the effort. Similarly, providing information on future costs and funding needs is important to help interagency partners coordinate and develop long-term strategic plans that align with future interagency efforts. We have found that for strategic planning to be done well, plans should demonstrate alignment between activities, core processes, and resources that support mission outcome. By including in its plan estimates of future costs and funding needed to support the activities in the plan, NNSA could help provide assurance that agencies are allocating appropriate resources for interagency efforts and that these resources are aligned with future activities and processes. The second reporting requirement called for an international engagement plan for building cooperation and transparency—including bilateral and multilateral efforts—to improve inspections, detection, and monitoring activities. We found that the 2018 plan provided detail on this requirement. The 2018 plan reiterates the nation’s commitment to the NPT and includes information on IAEA’s safeguards programs and U.S support for those programs. For example, under the plan, interagency partners are to continue to encourage countries through diplomatic outreach to conclude Additional Protocol agreements with IAEA. The third reporting requirement called for the plan to describe current and planned R&D efforts toward improving monitoring, detection, and in-field inspection and analysis capabilities, including persistent surveillance, remote monitoring, and rapid analysis of large data sets; and measures to coordinate technical and operational requirements early in the process. We found that the 2018 plan provided detail on this requirement. The plan includes detail on a wide range of R&D efforts and non-technical efforts that agencies are pursuing. For example, the plan reports that the Defense Advanced Research Projects Agency is starting a program that models millions of nodes and billions of connections to support the detection of WMD proliferation activities. In addition, the plan describes interagency groups involved in coordinating R&D requirements, such as the National Science and Technology Council Subcommittee on Nuclear Defense Research and Development. The fourth reporting requirement called for the plan to describe the engagement of relevant federal departments and agencies; the military departments; national laboratories; industry; and academia. We found that the 2018 plan provided detail on this requirement. The plan includes detail on the roles and responsibilities for interagency partners, as well as information on interagency organizations and working groups to coordinate efforts and reduce duplication. For example, the plan discusses the Department of State’s efforts to lead the interagency policy process on nonproliferation and manage global U.S. security policy, and the Department of Defense’s support of U.S. diplomatic efforts, including agreements with other defense departments, R&D cooperation, and multinational exercises. This 2018 plan represents the third effort by Administrations to address the nation’s nuclear proliferation verification and monitoring efforts. The 2018 plan provides more detail on these efforts than the 2015 plan and 2017 update. However, the plan does not include estimates of future costs and funding needs as required by the fiscal year 2018 NDAA. Costs and funding information can help congressional decisionmakers prioritize projects and identify potential long-term funding needs. Similarly, costs and funding information helps interagency partners understand what resources they are expected to contribute in the future and helps to ensure long-term strategic plans reflect an alignment between resources and interagency activities. By including in its plan estimates of future costs and funding needed to support the activities in the plan, NNSA could help provide assurance that agencies are allocating appropriate resources to the verification and monitoring effort and interagency activities, and that these resources are aligned with future activities and processes. We are making the following recommendation to NNSA: The Administrator of NNSA should include in its plan for verification and monitoring estimates of future costs and funding needed to support the activities in the plan. (Recommendation 1) We provided NNSA with a draft of this report for review and comment. NNSA provided written comments, which are summarized below and reproduced in appendix I; the agency neither agreed nor disagreed with our recommendation to include estimates of future costs and funding needed to support the activities in its plan for nuclear proliferation verification and monitoring. However, NNSA stated that it planned no further action with regard to costs and funding data. NNSA also provided technical comments, which we incorporated as appropriate. NNSA stated that it appreciated our recognition of improvements in the 2018 plan for verification and monitoring over the 2015 plan and the 2017 update. In its written comments, NNSA acknowledged that it did not include interagency cost and funding requirements in the 2018 plan over 10 years as required in the NDAA. The agency stated that it briefed the appropriate congressional committees before the release of the plan about the challenges and feasibility of providing the cost and funding data and received no objections on the omission of the data from the plan. NNSA also stated that it informed us of the briefings. We have added clarification in our report that NNSA officials believed they received agreement from congressional staff to exclude funding and cost estimates from its plan. NNSA stated that the NDAA did not prioritize the relative importance of the reporting requirements, and that we disproportionately weighted the one omission in our assessment, effectively overstating the importance of providing cost and funding information. In addition, NNSA identified challenges to the feasibility of providing interagency out-year cost and funding estimates, including the difficulty to quantify the level of R&D and associated funding required to achieve specific outcomes and that departments and agencies are unable to commit to aligning 10 year funding estimates with individual agencies’ timelines and internal processes for planning, programming, budgeting, and execution. NNSA’s statement suggests that it views nuclear proliferation verification and monitoring programs as being unique and different from other federal programs and that they should therefore be exempt from estimating their potential long-term resource burden on the federal budget. We disagree. Developing future cost and funding estimates for programs is central to effective interagency planning efforts. The efforts described in NNSA’s 2018 nuclear verification and monitoring plan span a diverse range of activities that are implemented across multiple agencies. The absence of cost and funding estimates for these efforts in NNSA’s plan raises questions as to whether there is an effective interagency process to coordinate these efforts and if the process is taking adequate account of resource constraints and making realistic assessments of program resource needs. In addition, information on future cost and funding estimates of federal programs provides Congress with a better understanding of the potential long-term funding needs and costs of the diverse efforts supporting the proliferation verification and monitoring mission. We believe this big picture view is important given the multiple congressional committees of jurisdiction—including appropriations, authorization, and oversight committees—for the efforts identified in NNSA’s plan. Regarding the feasibility of providing 10-year cost and funding estimates, we recognize the difficulty and uncertainty agencies face in estimating future funding needs. However, we do not believe developing such estimates is impossible. As we reported, the Department of Defense (DOD) and the Department of Energy (DOE) prepare an annual plan with 10 year cost and funding estimates for their ongoing nuclear sustainment and modernization efforts, including R&D efforts. NNSA also provided general technical comments addressing our findings on the cost and funding estimates that were not included in the plan, including comments on NNSA’s authority to obtain 10-year estimates from other agencies, and on the examples we cited of other interagency plans that include similar estimates. NNSA stated that it did not have authority to require other agencies to submit 10-year budget estimates for their efforts that are included in the plan. We noted in our report that Congress directed the President to include this element in the nuclear proliferation verification and monitoring plan. However, responsibility to prepare and submit the plan was delegated by the President to DOE. NNSA commented that the joint DOD-DOE annual nuclear sustainment and modernization plan is not comparable to the NNSA plan because the former primarily addresses capital projects and other material products, while the latter primarily addresses R&D activities. The reporting requirements for NNSA’s nuclear proliferation verification and monitoring plan were not limited to R&D efforts, but included cost and funding estimates for related activities and capabilities, including policy, operations, testing, and evaluation. NNSA’s comment focuses only on the difficulty of addressing cost and funding estimates for only one aspect (R&D) of nuclear proliferation verification and monitoring and ignores the possibility that estimates for non-R&D efforts may be more feasible and less difficult to report. Moreover, we have reported that the joint DOD- DOE plan on nuclear modernization includes 10-year DOD and DOE estimates for R&D, as well as estimates for related modernization efforts, including infrastructure, nuclear weapon life extension programs, delivery systems, nuclear command, control, and communications systems, and other related activities.

Countering the proliferation of nuclear weapons is a national security priority that is challenged by weapons advances from existing nuclear states and other actors possessing or attempting to possess nuclear weapons. To help address these issues, Congress directed the Administration in 2015 and 2017 to develop a plan for verification and monitoring relating to the potential proliferation of nuclear weapons, components of such weapons, and fissile material. GAO reviewed the first plan submitted to Congress in 2015, and an update submitted in 2017. GAO reported in March 2018 that this plan and update generally did not address the congressionally mandated reporting requirements. In the fiscal year 2018 NDAA, Congress directed the Administration to develop another plan and included a provision for GAO to review the plan. This report assesses whether the Administration's new plan provided details on the reporting requirements included in the NDAA. To determine whether the plan provided details on the reporting requirements, GAO reviewed the fiscal year 2018 plan and assessed whether the plan included details for each of the elements as required by the NDAA. GAO found that the 2018 plan provided details on most of the reporting requirements in the National Defense Authorization Act (NDAA) for Fiscal Year 2018, but did not include information on future costs and funding needs (see table below). In the NDAA, Congress directed the President to produce a plan that would address four reporting requirements: (1) a plan and roadmap on verification, detection and monitoring efforts, including details on costs and funding needs over 10 years, (2) an international engagement plan, (3) a research and development plan, and (4) a description of interagency engagement. The National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy, developed the plan and submitted it to Congress in April 2018. According to NNSA officials, NNSA did not include long-term costs and funding needs in the plan because identifying these needs is unrealistic for several reasons, including because agencies have little influence over the spending priorities of other departments outside of the President's budget process. However, NNSA and other agencies already develop plans with long-term funding priorities and cost estimates for other programs. Because the plan does not include any estimates on future costs and funding needs, it limits congressional understanding of the long-term affordability of the nation's verification and monitoring efforts and its ability to make necessary funding and policy decisions. GAO has previously reported that providing estimates of future costs and funding needs can help congressional decisionmakers prioritize projects and identify long-term funding needs. By including in its plan estimates of future costs and funding needed to support the activities in the plan, NNSA could help provide assurance that agencies are allocating appropriate resources to the verification and monitoring effort and that these resources are aligned with future activities and processes. GAO recommends that the Administrator of NNSA should include in its plan estimates of future costs and funding needed to support the activities in the plan. NNSA neither agreed nor disagreed with the recommendation, but said it planned no further action. GAO maintains that the recommendation is valid.
