Thorium: REAL Alternative Energy
Ethanol and other biofuels, hydrogen, fuel cells, solar generators, wind power, wave power: bah. Humbug. Silly money-eating boondoggles whose chief proponents are apparently incapable of operating a calculator. We have natural gas (a lot), we have coal (a lot); let's figure out how to use them.
And: we have thorium (a lot). - d

There's great rejoicing tonight in Salmon, Idaho, because Salmon is the closest town to the Lemhi Pass, and the Lemhi Pass is the location of America's largest and possibly the world's richest high grade thorium oxide deposits.
"So what?" Well, here's what's what.
On Oct. 2, 2008 Senator Hatch (R-UTt) and Senator Reid (D-NV), then as now the Senate Majority Leader, introduced into the agenda for consideration by the United States Senate a bi-partisan bill, S-3680, entitled Thorium Energy Independence and Security Act of 2008,
The press release put out by Senator Hatch's office that same day,
contained the following paragraph:
"Using thorium for nuclear power has a number of potential benefits over conventional uranium. As a resource, thorium is abundant in the U.S. and throughout the world. A thorium fuel rod would remain in the reactor about three times as long as conventional nuclear fuel, cutting the volume of spent nuclear fuel by as much as two-thirds. Also, thorium nuclear fuel would significantly reduce the possibility that weapons-grade material would result from the process. Finally, a thorium fuel cycle could be used to dispose of existing plutonium stockpiles, which is the national security goal."
The above paragraph sums up the arguments for using thorium based fuel as an alternative to uranium based fuel for nuclear reactors that I myself first wrote about on ResourceInvestor.com in 2006 in an article I called "Thorium: An Alternative to Uranium,"
I updated that article in early 2007 in my next thorium themed article," Thorium, An Alternative to Uranium, 2007 Update, "
.Later that year I wrote "Thorium, the Answer to the Question 'How Do You Hedge Uranium?"
. In February of 2008 I wrote "How to Invest in Rare Earths and Thorium ,"
, and now one year later I think that my timing has been right on the mark, and I want to tell you what has happened and what the natural resource investment opportunities for thorium are and are going to be.
I want to direct your attention to news releases that have been published since the beginning of 2009. If they don't quicken your interest in the potential of thorium, especially when combined with the Hatch-Reid Bill, then you are simply uninterested in the future direction of non-proliferative low-waste nuclear power. This technology uses a natural resource the United States now possesses in such abundance that, since American mining and refining technology for minor metals, and radioactive metals in particular, is the most advanced and safest in the world. It could make America the principal producer, refiner and exporter of the thorium fuels that are being developed around the world, because, my dear investing public,
America probably has more accessible high-grade deposits of thorium than anyone else
Back to the 2009 news: Check out the International Herald Tribune for February 3, 2009, and you will see the analytical news piece called "A model nuclear-power deal?
. This details the negotiations and agreement between the USA and the Arab states of the Persian Gulf, such as Dubai and Kuwait, that was done in Condoleezza Rice's last days as Secretary of State. It would give the Emirates the right to buy nuclear power reactor technology from American companies in return for the agreements of the Gulf governments not to ask for or obtain any technology that can be used to make nuclear weapons. As the article points out, a good way to achieve this goal, with no possibility of cheating by either side, is to utilize thorium-based fuel for the reactors. This deal has been announced since the Obama administration took office and therefore we must assume that it is in line with the new President's policies for reducing greenhouse gas emitting power plant construction and reducing and stopping the proliferation of nuclear weapons. It can be no coincidence that the Hatch-Reid Bill is about to be re-introduced into the new Congress. Clearly, the administration has signaled its support for amending the Atomic Energy Act of 1954 to include funding for research and development of thorium based fuels, thorium reactors, and thorium reactor waste disposal techniques.
I am personally aware of the fact that, even as I write, major American, Canadian, French and British nuclear engineering companies are forming strategic alliances to seek funding under Hatch-Reid to go forward with the development of thorium based nuclear power reactors for the production of electricity for civilian use.
One year ago at the SME, the USGS sponsored the first annual rare earth's seminar. The second annual one will be held at the SME annual meeting this year in Denver on Feb. 26. I attended last year's conference in Salt Lake City, and I asked, as did others, what about the thorium normally found in rare earth ore bodies in North America. The uniform answer from almost all of the miners attending was that "we contain it." It is removed early on in the separation of the light rare earths, lanthanum to neodymium, and is then contained by being put aside and immobilized. There is often uranium as well as thorium associated with rare earth ore bodies, so I was told that thorium containment is "no problemo" as some miners put it at the conference.
I noted that although everyone at the conference had knowledge of the possible use of thorium in non-proliferative low waste reactors they viewed that as a rather distant possibility and clearly then, in February 2008, classed thorium as a liability and as a cost to be contained.
As the song says, "What a difference a year makes." The Indian Atomic Energy Authority announced at the beginning of 2009 that it would convert an existing reactor to use thorium-based fuel, with the thorium coming from India's own monazite sands.
Even earlier than that in Hong Kong in September, I was told that the Chinese government had asked an American manager of a Bayanobo mining operation to tell them just what happened to the thorium separated there from the rare earths. He told me that he was instructed to gather and hold thorium concentrates from now on, and that they would be picked up by the Chinese nuclear power authority, because China was going ahead with the design and building of thorium based fuel for "thorium" reactors, since China has so much thorium as a byproduct of its world's largest rare earth mining operations.
Last week, Canada's Great Western Minerals Group, which told the SME conference in 2007 that its Hoidas Lake, Saskatchewan rare earth deposit was particularly low in thorium, and saw that as a positive, announced that it had bought a concession in the Republic of South Africa to reopen a mine for rare earths that was developed in the 1950s by AngloAmerican originally to produce thorium. Great Western further disclosed that a South African utility had made a deal with GW to have it "contain" the thorium produced in the rare earth mining operation in concrete, so that the utility could take it to their own site when they have prepared it. The utility told them that the South African government has evinced a strong interest in building thorium-based nuclear reactors and that the utility wants to have a domestic fuel source.
So now, what does this have to do with Salmon, Idaho? The answer is that it is the closest town to the claims of the private junior mining company, Thorium Energy Inc., which announced last year at the SME that its Lemhi Pass, Idaho and other nearby properties were being validated with regard to reserves and resources of thorium, which the company said looked like they might be the richest and most extensive in North America. The USGS has now recognized that the company's thorium reserves and resources are among the largest in the world and recently amended its Commodity Survey of Thorium to reflect that. Thorium Energy's claims also contain substantial quantities of the rare earths, particularly of the light rare earths. An engineering manager at an American nuclear engineering company moving forward on the development of thorium reactors pointed out to me last week that TEI could produce thorium as a product along with rare earth elements as a secondary product or the other way around. In the one case, he noted that TEI would become and could well become the world's first primary thorium miner in half a century, and perhaps the largest one ever if the validation is accurate.
The engineer thought that as a step towards American energy self sufficiency and independence, it was potentially a giant step. Perhaps we are about to step into the age of the last of the power metals to be developed for mankind's use, thorium.

Just be aware that Thorium was used to make lamp mantles for years because it glows very brightly. Two kids made a nuclear reactor for a bet out of lamp mantles and it worked.
But be aware that there was a company in this city that made and sold Thorium lamp mantles and the majority of it's staff died of stomach cancer.
You have been warned.

So thorium sounds interesting and abundant, so why haven't they used it sooner? Is there some catch?

From wikipedia:
Thorium as a nuclear fuel
Main article:
Thorium fuel cycle
Thorium, as well as uranium and plutonium, can be used as fuel in a nuclear reactor. Although not fissile itself, 232Th will absorb slow neutrons to produce 233U, which is fissile. Hence, like 238U, it is fertile. Theoretically thorium is more suitable fuel source than uranium: thorium is about 550 times more abundant in nature than uranium-235, potentially all of thorium fuel can be usefully burned in nuclear fission (current state of the art uranium based reactors burn only about 1-2% of fuel), thorium is fairly evenly spread around Earth with a lot of countries having huge supplies of it, thorium fuel cycle creates mainly Uranium-233 contaminated with Uranium-232 which makes it ill suited to weapons proliferation.
Problems include the high cost of fuel fabrication due partly to the high radioactivity of 233U which is a result of its contamination with traces of the short-lived 232U; the similar problems in recycling thorium due to highly radioactive 228Th; some weapons proliferation risk of 233U; and the technical problems (not yet satisfactorily solved) in reprocessing. Much development work is still required before the thorium fuel cycle can be commercialized, and the effort required seems unlikely while (or where) abundant uranium is available.
Nevertheless, the thorium fuel cycle, with its potential for breeding fuel without fast neutron reactors, holds considerable potential long-term benefits. Thorium is significantly more abundant than uranium, and is a key factor in sustainable nuclear energy. Perhaps more importantly, thorium produces several orders of magnitude less long-lived radioactive waste.
One of the earliest efforts to use a thorium fuel cycle took place at Oak Ridge National Laboratory in the 1960s. An experimental reactor was built based on molten salt reactor technology to study the feasibility of such an approach, using thorium-fluoride salt kept hot enough to be liquid, thus eliminating the need for fabricating fuel elements. This effort culminated in the Molten-Salt Reactor Experiment that used 232Th as the fertile material and 233U as the fissile fuel. Due to a lack of funding, the MSR program was discontinued in 1976.
I wish I understood more about this...Why was there no funding in 1976? Was it because of the "abundant uranium...available"? Is it STILL all about special interests? (the uranium industry--does this really exist? IS there a uranium "industry"?)
Shari--off to do more research before I get sidetracked...

Here's some more information about it:
Safety a possible disadvantage
Breeder Reactors (Fast Neutron Reactors)
"Of the fissile materials usable for practical nuclear energy production, only uranium-235 occurs in any substantial quantities in nature. The other two, plutonium-239 and uranium-233, must be made from uranium-238 and thorium-232 respectively, which are far more abundant than naturally-occurring fissile uranium-235. The process of converting "fertile" uranium-238 and thorium-232 into fissile materials is called "breeding," evidently by analogy with biological reproduction.
Since doubling times for breeding U-233 are far longer than for breeding Pu-239, almost all breeder reactors so far have been built to breed Pu-239. A further disadvantage of thorium-232-based breeder reactors cycle is the high gamma radioactivity due to contaminants in recovered uranium-233. This radioactivity arises mainly from the decay products of uranium-232, which is created in thorium-uranium fueled breeders by various nuclear reactions.
India seems to be the only country with a substantial active program to pursue U-233 breeding, since it has very large thorium-232 reserves, which are far greater than its domestic uranium-238 resources.
Fast breeders, by definition, need no moderators, which slow down neutrons, since they use fast neutrons for fission and breeding. They cannot use ordinary water or heavy water as a coolant because these materials also act as moderators. Liquid sodium, which has a mass number of 23, compared to 1 for ordinary hydrogen and 2 for deuterium, is the most common breeder reactor coolant. Since a coolant must continually flow across fuel elements, it must be a gas or liquid. Since sodium is a solid at room temperature, it must be maintained in liquid form in a breeder reactor by heating it continually, even when the reactor is shut down.
Sodium catches fire on contact with air and explodes on contact with water. Further, the nucleus of ordinary sodium absorbs a neutron and turns into a highly radioactive isotope sodium-24. This is a major threat in case of a breeder reactor accident. To prevent leakage of sodium-24 into the environment, sodium-cooled reactors are designed with two liquid sodium loops. The secondary, non-radioactive sodium loop draws heat from the primary loop and, in turn, is used to boil water in a steam generator. The December 1995 accident at the Japanese breeder reactor at Monju involved a large leak of sodium from the secondary loop.
Despite its theoretical attractiveness in converting non-fissile into fissile material, the breeder reactor has turned out to be a far tougher technology than thermal reactors. Despite five decades of effort during which many pilot and "demonstration" plants have been built, the sodium-cooled breeder reactor design remains on the margin of commercial nuclear technology."

The real questions are:
1) Even though 2/3 is a lot less waste than conventional reactors, how much waste would we be talking if we moved over to it?
2) Uranium and its reactive byproducts have a half-life measured in millions of years. How would thorium compare?
3) How does it compare to uranium safety-wise? Is it more likely, less likely, or just as much a risk as conventional uranium reactors?

Excellent question. The first thing we must know is, well, how much nuclear waster does a regular plant produce?
I went looking for the answer once. It's tough to find, because the anti-nuke folks inflate the number by including very low level nuclear waste, like the paper suits and booties worn by technicians that are essentially harmless, while the nuke proponents try to cut the answer down to the waste that is actually output from the plant but don't recognize the need for decommissioning down the line; those steel containment vessels are going to be hot, though not markedly so, and not forever.
If you count what would be left if we reprocessed our fuel like the French (currently illegal courtesy of Jimmy Carter), truly high level waste would amount to about a cupful for a family of four for their lifetimes. Without reprocessing, more like a cigar box. This is nasty, deadly, long-life stuff, that needs to be vitrified and buried in Yucca Mountain with a lame Crosby/Nash song playing over it to drive people away. Compare that with the amount of gasified mercury, cadmium, lead, sulfur, and yes, uranium and thorium put directly into the atmosphere by a coal plant, it looks like a HUGE bargain. Especially when you cut it by two-thirds for thorium reactors.
Sorry, no link—this is off the top of my head. YMMV.

Note: This article is being reprinted here as an example of what NOT to do with radioactive materials. Please do NOT attempt to recreate any part of these experiments for the following reasons:
You will most likely poison yourself and/or others
Nobody really needs an unsafe homemade reactor (especially one made of duct tape and foil)
If enough people try these dangerous experiments, the government will try to outlaw any sort of legitimate private experiments with radioactivity or possession of any radioactive minerals or materials (thus spoiling all of our fun).
What happened when a teenager tried a dangerous experiment in his back yard
Tale of the Radioactive Boy Scout.
Golf Manor, a subdivision in Commerce Township, Mich., some 25 miles outside of Detroit, is the kind of place where nothing unusual is supposed to happen, where the only thing lurking around the corner is an ice-cream truck. But June 26, 1995, was not a typical day.
Ask Dottie Pease. Cruising down Pinto Drive, Pease saw half a dozen men crossing her neighbor's lawn. Three, in respirators and white moon suits, were dismantling her next-door neighbor's shed with electric saws, stuffing the pieces into large steel drums emblazoned with radioactive warning signs.
Huddled with a group of neighbors, Pease was nervous. "I was pretty disturbed," she recalls. Publicly, the employees of the Environmental Protection Agency (EPA) that day said there was nothing to fear. The truth is far more bizarre: the shed was dangerously irradiated and, according to the EPA, up to 40,000 residents of the area could be at risk.
The cleanup was provoked by the boy next door, David Hahn. He had attempted to build a nuclear reactor in his mother's shed following a Boy Scout merit-badge project.
Grander Ambitions
David Hahn's early years were seemingly ordinary. The blond, gangly boy played baseball and soccer, and joined the Boy Scouts. His parents, Ken and Patty, had divorced, and David lived with his father and stepmother, Kathy, in nearby Clinton Township. He spent weekends in Golf Manor with his mother and her boyfriend, Michael Polasek.
An abrupt change came at age ten, when Kathy's father gave David The Golden Book of Chemistry Experiments. David became immersed. By age 12 he had digested his father's college chemistry textbooks; by 14 he had made nitroglycerin.
One night his house in Clinton Township was rocked by an explosion in the basement. Ken and Kathy found David semiconscious on the floor. He had been pounding some substance with a screwdriver and ignited it. He was rushed to the hospital to have his eyes flushed.
Kathy then forbade David from experimenting in her home. So he shifted his operations to his mother's shed in Golf Manor. Neither Patty nor Michael had any idea what the shy teenager was up to, although they thought it was odd that David often wore a mask in the shed, and would sometimes discard his clothing after working there until two in the morning. They chalked it up to their own limited education.
Michael does, however, remember David saying, "One of these days we're gonna run out of oil."
Convinced he needed discipline, David's father, Ken, felt the solution lay in a goal that he didn't himself achieve, Eagle Scout, which requires 21 merit badges. David earned a merit badge in Atomic Energy in May 1991, five months shy of his 15th birthday. By now, though, he had grander ambitions.
Concocted identity
He was determined to irradiate anything he could, and decided to build a neutron "gun." To obtain radioactive materials, David used a number of cover stories and concocted a new identity.
He wrote to the Nuclear Regulatory Commission (NRC), claiming to be a physics instructor at Chippewa Valley High School. The agency's director of isotope production and distribution, Donald Erb, offered him tips on isolating and obtaining radioactive elements, and explained the characteristics of some isotopes, which, when bombarded with neutrons, can sustain a chain reaction.
When David asked about the risks, Erb assured him that the "dangers are very slight," since "possession of any radioactive materials in quantities and forms sufficient to pose any hazard is subject to Nuclear Regulatory Commission (or equivalent) licensing."
David learned that a tiny amount of the radioactive isotope americium-241 could be found in smoke detectors. he contacted smoke-detector companies and claimed that he needed a large number for a school project. One company sold him about a hundred broken detectors for a dollar apiece.
Not sure where the americium was located, he wrote to an electronics firm in Illinois. A customer-service representative wrote back to say she'd be happy to help out with "your report." Thanks to her help, David extracted the material. He put the americium inside a hollow block of lead with a tiny hole pricked in one side so that alpha rays would stream out. In front of the block he placed a sheet of aluminum, its atoms absorb alpha rays and kick out neutrons. His neutron gun was ready.
The mantle in gas lanterns, the small cloth pouch over the flame, is coated with a compound containing thorium-232. When bombarded with neutrons it produces uranium-233, which is fissionable. David bought thousands of lantern mantles from surplus stores and blowtorched them into a pile of ash.
To isolate the thorium from the ash, he purchased $1000 worth of lithium batteries and cut them in half with wire cutters. He placed the lithium and thorium ash together in a ball of aluminum foil and heated the ball with a Bunsen burner. This purified the thorium to at least 9000 times the level found in nature, and up to 170 times the level that requires NRC licensing. But David's americium gun wasn't strong enough to transform thorium into uranium.
More Help From the NRC
David held a series of after-school jobs at fast-food joints, grocery stores and furniture warehouses, but work was merely a means of financing his experiments. Never an enthusiastic student, he fell behind in school, scoring poorly on state math and reading tests (he did, however, ace the test in science).
Wanting radium for a new gun, David began visiting junkyards and antique stores in search of radium-coated clocks. He'd chip paint from them and collect it.
It was slow going until one day, while driving through Clinton Township, he says he came across an old table clock in an antique shop. In the hack of the clock he discovered a vial of radium paint. He bought the clock for $10.
Next he concentrated the the radium and dried it into a salt form. Whether he fully realized it or not, he was putting himself in danger.
The NRC's Erb had told him that "nothing produces neutrons from alpha reactions as well as beryllium." David says he had a friend swipe a strip of beryllium from a chemistry lab, then placed it in front of the lead block that held the radium. His cute little americium gun was now a more powerful radium gun.
David had located some pitchblende, an ore containing tiny amounts of uranium, and pulverized it with a hammer. He aimed the gun at the powder, hoping to produce at least some fissionable atoms. It didn't work. The neutron particles, the bullets in his gun, were moving too fast.
To slow them down, he added a filter, then targeted his gun again. This time the uranium powder appeared to grow more radioactive by the day.
"Imminent Danger"
Now 17, David hit on the idea of building a model breeder reactor, a nuclear reactor that not only generates electricity, but also produces new fuel. His model would use the actual radioactive elements and produce real reactions. His blueprint was a schematic in one of his father's textbooks.
Ignoring safety, David mixed his radium and americium with beryllium and aluminum, all of which he wrapped in aluminum foil, forming a makeshift reactor core. He surrounded this radioactive ball with a blanket of small foil-wrapped cubes of thorium ash and uranium powder, tenuously held together with duct tape.
"It was radioactive as heck," David says, "far greater than at the time of assembly." Then he began to realize that he could be putting himself and others in danger.
When David's Geiger counter began picking up radiation five doors from his mom's house, he decided that he had "too much radioactive stuff in one place" and began to disassemble the reactor. He hid some of the material in his mother's house, left some in the shed, and packed most of the rest into the trunk of his Pontiac.
At 2:40 a.m. on August 31, 1994, Clinton Township police responded to a call concerning a young man who had been apparently stealing tires from a car. When the police arrived, David told them he was meeting a friend. Unconvinced, officers decided to search his car.
They opened the trunk and discovered a toolbox shut with a padlock and sealed with duct tape. The trunk also contained foil-wrapped cubes of mysterious gray powder, small disks and cylindrical metal objects, and mercury switches. The police were especially alarmed by the toolbox, which David said was radioactive and which they feared was an atomic bomb.
The discovery eventually triggered the Federal Radiological Emergency Response Plan, and state officials would become involved in consultations with the EPA and NRC.
At the shed, radiological experts found an aluminum pie pan, a Pyrex cup, a milk crate and other materials strewn about, contaminated at up to 1000 times the normal levels of background radiation. Because some of this could be moved around by wind and rain, conditions at the site, according to an EPA memo, "present an imminent endangerment to public health."
After the moon-suited workers dismantled the shed, they loaded the remains into 39 sealed barrels that were trucked to the Great Salt Lake Desert. There, the remains of David's experiments were entombed with other radioactive debris.
"These are conditions that regulations never envision," says Dave Minnaar, radiological expert with Michigan's Department of Environmental Quality. "It's simply presumed that the average person wouldn't have the technology or materials required to experiment in these areas."
David Hahn is now in the Navy, where he reads about steroids, melanin, genetic codes, prototype reactors, amino acids and criminal law. "I wanted to make a scratch in life," he explains now. "I've still got time." Of his exposure to radioactivity he says, "I don't believe I took more than five years off my life."

Uranium Is So Last Century Enter Thorium, the New Green Nuke
The thick hardbound volume was sitting on a shelf in a colleagues office when Kirk Sorensen spotted it. A rookie NASA engineer at the Marshall Space Flight Center, Sorensen was researching nuclear-powered propulsion, and the books title Fluid Fuel Reactors jumped out at him. He picked it up and thumbed through it. Hours later, he was still reading, enchanted by the ideas but struggling with the arcane writing. I took it home that night, but I didnt understand all the nuclear terminology, Sorensen says. He pored over it in the coming months, ultimately deciding that he held in his hands the key to the worlds energy future.
Published in 1958 under the auspices of the Atomic Energy Commission as part of its Atoms for Peace program, Fluid Fuel Reactors is a book only an engineer could love: a dense, 978-page account of research conducted at Oak Ridge National Lab, most of it under former director Alvin Weinberg. What caught Sorensens eye was the description of Weinbergs experiments producing nuclear power with an element called thorium.
At the time, in 2000, Sorensen was just 25, engaged to be married and thrilled to be employed at his first serious job as a real aerospace engineer. A devout Mormon with a linebackers build and a marines crew cut, Sorensen made an unlikely iconoclast. But the book inspired him to pursue an intense study of nuclear energy over the next few years, during which he became convinced that thorium could solve the nuclear power industrys most intractable problems. After it has been used as fuel for power plants, the element leaves behind minuscule amounts of waste. And that waste needs to be stored for only a few hundred years, not a few hundred thousand like other nuclear byproducts. Because its so plentiful in nature, its virtually inexhaustible. Its also one of only a few substances that acts as a thermal breeder, in theory creating enough new fuel as it breaks down to sustain a high-temperature chain reaction indefinitely. And it would be virtually impossible for the byproducts of a thorium reactor to be used by terrorists or anyone else to make nuclear weapons.
Weinberg and his men proved the efficacy of thorium reactors in hundreds of tests at Oak Ridge from the 50s through the early 70s. But thorium hit a dead end. Locked in a struggle with a nuclear- armed Soviet Union, the US government in the 60s chose to build uranium-fueled reactors in part because they produce plutonium that can be refined into weapons-grade material. The course of the nuclear industry was set for the next four decades, and thorium power became one of the great what-if technologies of the 20th century.
Today, however, Sorensen spearheads a cadre of outsiders dedicated to sparking a thorium revival. When hes not at his day job as an aerospace engineer at Marshall Space Flight Center in Huntsville, Alabama or wrapping up the masters in nuclear engineering he is soon to earn from the University of Tennessee he runs a popular blog called Energy From Thorium. A community of engineers, amateur nuclear power geeks, and researchers has gathered around the sites forum, ardently discussing the future of thorium. The site even links to PDFs of the Oak Ridge archives, which Sorensen helped get scanned. Energy From Thorium has become a sort of open source project aimed at resurrecting long-lost energy technology using modern techniques.
And the online upstarts arent alone. Industry players are looking into thorium, and governments from Dubai to Beijing are funding research. India is betting heavily on the element.
The concept of nuclear power without waste or proliferation has obvious political appeal in the US, as well. The threat of climate change has created an urgent demand for carbon-free electricity, and the 52,000 tons of spent, toxic material that has piled up around the country makes traditional nuclear power less attractive. President Obama and his energy secretary, Steven Chu, have expressed general support for a nuclear renaissance. Utilities are investigating several next-gen alternatives, including scaled-down conventional plants and pebble bed reactors, in which the nuclear fuel is inserted into small graphite balls in a way that reduces the risk of meltdown.
Those technologies are still based on uranium, however, and will be beset by the same problems that have dogged the nuclear industry since the 1960s. It is only thorium, Sorensen and his band of revolutionaries argue, that can move the country toward a new era of safe, clean, affordable energy.
Named for the Norse god of thunder, thorium is a lustrous silvery-white metal. Its only slightly radioactive; you could carry a lump of it in your pocket without harm. On the periodic table of elements, its found in the bottom row, along with other dense, radioactive substances including uranium and plutonium known as actinides.
Actinides are dense because their nuclei contain large numbers of neutrons and protons. But its the strange behavior of those nuclei that has long made actinides the stuff of wonder. At intervals that can vary from every millisecond to every hundred thousand years, actinides spin off particles and decay into more stable elements. And if you pack together enough of certain actinide atoms, their nuclei will erupt in a powerful release of energy.
To understand the magic and terror of those two processes working in concert, think of a game of pool played in 3-D. The nucleus of the atom is a group of balls, or particles, racked at the center. Shoot the cue ball a stray neutron and the cluster breaks apart, or fissions. Now imagine the same game played with trillions of racked nuclei. Balls propelled by the first collision crash into nearby clusters, which fly apart, their stray neutrons colliding with yet more clusters. Voilè0: a nuclear chain reaction.
Actinides are the only materials that split apart this way, and if the collisions are uncontrolled, you unleash hell: a nuclear explosion. But if you can control the conditions in which these reactions happen by both controlling the number of stray neutrons and regulating the temperature, as is done in the core of a nuclear reactor you get useful energy. Racks of these nuclei crash together, creating a hot glowing pile of radioactive material. If you pump water past the material, the water turns to steam, which can spin a turbine to make electricity.
Uranium is currently the actinide of choice for the industry, used (sometimes with a little plutonium) in 100 percent of the worlds commercial reactors. But its a problematic fuel. In most reactors, sustaining a chain reaction requires extremely rare uranium-235, which must be purified, or enriched, from far more common U-238. The reactors also leave behind plutonium-239, itself radioactive (and useful to technologically sophisticated organizations bent on making bombs). And conventional uranium-fueled reactors require lots of engineering, including neutron-absorbing control rods to damp the reaction and gargantuan pressurized vessels to move water through the reactor core. If something goes kerflooey, the surrounding countryside gets blanketed with radioactivity (think Chernobyl). Even if things go well, toxic waste is left over.
When he took over as head of Oak Ridge in 1955, Alvin Weinberg realized that thorium by itself could start to solve these problems. Its abundant the US has at least 175,000 tons of the stuff and doesnt require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind.
Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the labs finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction the billiard balls colliding happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.
In 1965, Weinberg and his team built a working reactor, one that suspended the byproducts of thorium in a molten salt bath, and he spent the rest of his 18-year tenure trying to make thorium the heart of the nations atomic power effort. He failed. Uranium reactors had already been established, and Hyman Rickover, de facto head of the US nuclear program, wanted the plutonium from uranium-powered nuclear plants to make bombs. Increasingly shunted aside, Weinberg was finally forced out in 1973.
That proved to be the most pivotal year in energy history, according to the US Energy Information Administration. It was the year the Arab states cut off oil supplies to the West, setting in motion the petroleum-fueled conflicts that roil the world to this day. The same year, the US nuclear industry signed contracts to build a record 41 nuke plants, all of which used uranium. And 1973 was the year that thorium R&D faded away and with it the realistic prospect for a golden nuclear age when electricity would be too cheap to meter and clean, safe nuclear plants would dot the green countryside.
When Sorensen and his pals began delving into this history, they discovered not only an alternative fuel but also the design for the alternative reactor. Using that template, the Energy From Thorium team helped produce a design for a new liquid fluoride thorium reactor, or LFTR (pronounced lifter), which, according to estimates by Sorensen and others, would be some 50 percent more efficient than todays light-water uranium reactors. If the US reactor fleet could be converted to LFTRs overnight, existing thorium reserves would power the US for a thousand years.
Overseas, the nuclear power establishment is getting the message. In France, which already generates more than 75 percent of its electricity from nuclear power, the Laboratoire de Physique Subatomique et de Cosmologie has been building models of variations of Weinbergs design for molten salt reactors to see if they can be made to work efficiently. The real action, though, is in India and China, both of which need to satisfy an immense and growing demand for electricity. The worlds largest source of thorium, India, doesnt have any commercial thorium reactors yet. But it has announced plans to increase its nuclear power capacity: Nuclear energy now accounts for 9 percent of Indias total energy; the government expects that by 2050 it will be 25 percent, with thorium generating a large part of that. China plans to build dozens of nuclear reactors in the coming decade, and it hosted a major thorium conference last October. The Peoples Republic recently ordered mineral refiners to reserve the thorium they produce so it can be used to generate nuclear power.
In the United States, the LFTR concept is gaining momentum, if more slowly. Sorensen and others promote it regularly at energy conferences. Renowned climatologist James Hansen specifically cited thorium as a potential fuel source in an Open Letter to Obama after the election. And legislators are acting, too. At least three thorium-related bills are making their way through the Capitol, including the Senates Thorium Energy Independence and Security Act, cosponsored by Orrin Hatch of Utah and Harry Reid of Nevada, which would provide $250 million for research at the Department of Energy. I dont know of anything more beneficial to the country, as far as environmentally sound power, than nuclear energy powered by thorium, Hatch says. (Both senators have long opposed nuclear waste dumps in their home states.)
Unfortunately, $250 million wont solve the problem. The best available estimates for building even one molten salt reactor run much higher than that. And there will need to be lots of startup capital if thorium is to become financially efficient enough to persuade nuclear power executives to scrap an installed base of conventional reactors. What we have now works pretty well, says John Rowe, CEO of Exelon, a power company that owns the countrys largest portfolio of nuclear reactors, and it will for the foreseeable future.
Critics point out that thoriums biggest advantage its high efficiency actually presents challenges. Since the reaction is sustained for a very long time, the fuel needs special containers that are extremely durable and can stand up to corrosive salts. The combination of certain kinds of corrosion-resistant alloys and graphite could meet these requirements. But such a system has yet to be proven over decades.
And LFTRs face more than engineering problems; theyve also got serious perception problems. To some nuclear engineers, a LFTR is a little unsettling. Its a chaotic system without any of the closely monitored control rods and cooling towers on which the nuclear industry stakes its claim to safety. A conventional reactor, on the other hand, is as tightly engineered as a jet fighter. And more important, Americans have come to regard anything thats in any way nuclear with profound skepticism.
So, if US utilities are unlikely to embrace a new generation of thorium reactors, a more viable strategy would be to put thorium into existing nuclear plants. In fact, work in that direction is starting to happen thanks to a US company operating in Russia.
Located outside Moscow, the Kurchatov Institute is known as the Los Alamos of Russia. Much of the work on the Soviet nuclear arsenal took place here. In the late 80s, as the Soviet economy buckled, Kurchatov scientists found themselves wearing mittens to work in unheated laboratories. Then, in the mid-90s, a savior appeared: a Virginia company called Thorium Power.
Founded by another Alvin American nuclear physicist Alvin Radkowsky Thorium Power, since renamed Lightbridge, is attempting to commercialize technology that will replace uranium with thorium in conventional reactors. From 1950 to 1972, Radkowsky headed the team that designed reactors to power Navy ships and submarines, and in 1977 Westinghouse opened a reactor he had drawn up with a uranium thorium core. The reactor ran efficiently for five years until the experiment was ended. Radkowsky formed his company in 1992 with millions of dollars from the Initiative for Proliferation Prevention Program, essentially a federal make-work effort to keep those chilly former Soviet weapons scientists from joining another team.
The reactor design that Lightbridge created is known as seed-and-blanket. Its core consists of a seed of enriched uranium rods surrounded by a blanket of rods made of thorium oxide mixed with uranium oxide. This yields a safer, longer-lived reaction than uranium rods alone. It also produces less waste, and the little bit it does leave behind is unsuitable for use in weapons.
CEO Seth Grae thinks its better business to convert existing reactors than it is to build new ones. Were just trying to replace leaded fuel with unleaded, he says. You dont have to replace engines or build new gas stations. Grae is speaking from Abu Dhabi, where he has multimillion-dollar contracts to advise the United Arab Emirates on its plans for nuclear power. In August 2009, Lightbridge signed a deal with the French firm Areva, the worlds largest nuclear power producer, to investigate alternative nuclear fuel assemblies.
Until developing the consulting side of its business, Lightbridge struggled to build a convincing business model. Now, Grae says, the company has enough revenue to commercialize its seed-and-blanket system. It needs approval from the US Nuclear Regulatory Commission which could be difficult given that the design was originally developed and tested in Russian reactors. Then theres the nontrivial matter of winning over American nuclear utilities. Seed-and-blanket doesnt just have to work it has to deliver a significant economic edge.
For Sorensen, putting thorium into a conventional reactor is a half measure, like putting biofuel in a Hummer. But he acknowledges that the seed-and-blanket design has potential to get the country on its way to a greener, safer nuclear future. The real enemy is coal, he says. I want to fight it with LFTRs which are like machine guns instead of with light-water reactors, which are like bayonets. But when the enemy is spilling into the trench, you affix bayonets and go to work. The thorium battalion is small, but as nuclear physics demonstrates tiny forces can yield powerful effects.

Democrats Take House by a Wide Margin
The House of Representatives will be under Democratic control next January for the first time since 1994. Voters turned out Republican incumbents in races across the country Tuesday, with Democrats gaining at least 28, well more than the 15 they needed to win the majority.

RENEE MONTAGNE, host:
This is MORNING EDITION from NPR News. I'm Renee Montagne.
STEVE INSKEEP, host:
And I'm Steve Inskeep.
Representative TOM REYNOLDS (Republican, New York): I've got to congratulate what will be, I believe, speaker-designate Pelosi to be congratulated as first woman speaker. My goal and job will be to make sure she never sets the record that Denny Hastert has in the House, that be one of the longest serving
INSKEEP: That's the Republican congressman who was in charge of keeping Dennis Hastert speaker of the House. Tom Reynolds kept his own seat in New York, but too many of his fellow Republicans weren't so lucky. NPR's Brian Naylor reports this morning on what happened and why.
BRIAN NAYLOR: In 1994, the Republican revolution ended 40 years of Democratic control of the House. Not since then has there been the kind of sweep of an incumbent party as occurred yesterday. This time it was the Republicans who were purged by Democratic candidates who campaigned on little more than the promise of change.
One of the first incumbents to fall was Republican Nancy Johnson, who served 12 terms in the House, longer than any House member ever had from Connecticut. But despite her seniority and power, she was undone by Democratic state Senator Chris Murphy, who linked Johnson with President Bush and criticized her support for the war in Iraq. He addressed his cheering supporters last night.
Representative CHRIS MURPHY (Democrat, Connecticut): Let's talk about what this election means tonight, and we hope what it means across this country. It means that for the millions of people around this country who are uninsured, for the millions more seniors across this country who are struggling to pay for their health care, it means that after today things will change.
(Soundbite of cheering)
NAYLOR: Nancy Johnson's colleague from the House Ways and Means Committee, Clay Shaw of Florida, next in line to become chairman of the panel, was another senior member to fall, ousted by Democrat Ron Klein. Not just one but both Republican members from New Hampshire - Charles Bass and Jeb Bradley - were defeated; as were three GOP members from Indiana: Chris Chocola, John Hostettler and Mike Sodrel. Sodrel lost to former Democratic Congressman Baron Hill.
Mr. BARON HILL (Representative, Indiana): We've got a Congress I think that now has the opportunity to ask the tough questions of this administration and to clean up the mess in Washington, D.C.
(Soundbite of cheering)
NAYLOR: At least three Republican incumbents from New York and at least three from Pennsylvania lost yesterday. New York Republican Sue Kelly was defeated by Democrat John Hall, well known to fans of the pop group Orleans. In Arizona, Republican J.D. Hayworth lost, and Democrats easily picked up an open seat in the Tucson area.
Nearly all GOP incumbents tied to scandals were defeated. In Pennsylvania, Curt Weldon, who faces an FBI investigation into whether he illegally steered federal contracts to family members, lost to retired Navy Vice Admiral Joe Sestak. Pennsylvania Republican Don Sherwood, who allegedly physically abused his mistress, lost to Democrat Christopher Carney.
In Ohio, the seat vacated by Republican Bob Ney, who pleaded guilty as part of the Abramoff influence peddling scandal, went to Democrat Zack Space. The seat vacated by Texas Republican Tom DeLay was won by former Congressman Nick Lampson. And the Florida seat left open when Republican Mark Foley resigned was won by Democrat Tim Mahoney.
There were a few bright spots for the GOP. Connecticut Republican Chris Shays won a narrow victory in his suburban district, despite the unpopularity of the war and the president.
Representative CHRIS SHAYS (Republican, Connecticut): This is the most important point I can make tonight: Tell the American people the truth and they'll tell you the right thing to do.
NAYLOR: But Shays was a rare exception. It was, said Speaker Dennis Hastert, a difficult night for Republicans.
Representative DENNIS HASTERT (Republican, Illinois): We watched some of the House races, especially the east; it's been kind of tough out there.
NAYLOR: At the other end of the happiness scale stood California Democrat Nancy Pelosi. As Democratic leader, she's now in line to become the first woman speaker of the House. She told a cheering crowd in Washington last night that Americans voted for a new direction.
Representative NANCY PELOSI (Democrat, California): And nowhere did the American people make it more clear that we need a new direction than in the war in Iraq. Stay the course has not made our country safer, has not honored our commitment to our troops, and has not made the region more stable.
NAYLOR: Pelosi promised to work with new Republican minority in a bipartisan way. But first, there are a few intraparty issues to deal with. Already, two senior Democrats - Steny Hoyer of Maryland and John Murtha of Pennsylvania -are seeking support to become House majority leader, second in command after Pelosi.
And there are likely to be leadership changes in the Republican ranks as well, especially as the scope of the GOP defeat sinks in. But the biggest question may be how the Democrats will define their relationship with President Bush as they exercise power in Washington for the first time in over a decade.

On the other hand, the prosecutor probably will try to prove the existence of an international conflict in the trial against Dario Kordic. Not only that; if the court accepts prosecutor's proposal for the modification of the indictment, it will cover a much wider territory than the Lasva valley, probably the whole Croatian Community of Herceg-Bosna. It can be heard unofficially that the prosecutor will attempt to prove the links between Kordic and the Croatian state and political leaders.
Regarding Vukovar, two respected lawyers (both wish to remain anonymous) who have collaborated with the Hague Tribunal only appear to have different views. The first one says that he doesn't believe that the court will decide that there was an international conflict in Vukovar in 1991 because Croatia was at the time not recognized as an independent state and the international community hadn't yet announced that it considered the Socialist Federal Republic of Yugoslavia to be dissolved. The other one states that the decision about the existence of an international conflict is probable because of the existence of two armies, but that the court will not decide which army was an occupying force, because of legal (SFRY was an internationally recognized state at the time and Croatia had proclaimed independence) and political issues - judgments of the International Tribunal shouldn't encourage other separatist movements. Both lawyers are fairly certain that the court will decide for the existence of an international conflict in the cases against Croats from Bosnia-Hercegovina, if not in Blaskic case, than in the trial against Kordic, where the indictment covers a wider territory.
Because of lack of caution and unnecessary mistakes Croatia has objectively been brought in the position to become according to the judgments of the International Tribunal the only foreign participant in the war in Bosnia-Hercegovina and indirectly the only aggressor. Both of the mentioned lawyers believe that the matter of war reparations is unlikely to surface in the future. Namely, war reparations could only be imposed by an international court and only in theory. Bosnia-Hercegovina would first have to raise the issue in the court, which is unlikely because of political relations with Croatia; then the court decides whether there is a basis to accept the accusation, which is unlikely, then makes a more systematic investigation of the validity of the Hague International Tribunal judgment. Even it it confirms the decision about the international conflict, the reparation problem can only be resolved with the agreement of both states. For example in the dispute between the USA and Nicaragua in which the International Court of Justice concluded in the verdict that the American influence on the Nicaraguan Contras internationalized the conflict, Nicaragua refrained from further prosecution after the initial moral victory knowing that the USA would never accept to pay war reparations.
Nevertheless, a verdict of the International Tribunal for war crimes in the former Yugoslavia about an international conflict would certainly have political repercussions and influence the policy of the International Community with respect to Croatia. Besides, the official history of the last eight years in this region will largely be written in the Hague, and not in Croatia, Bosnia-Hercegovina or Serbia. Thus, it would do no harm if we also realized the importance of the Tribunal and began to approach it as a court and not a political discussion club. We are already very late, but better late then never.

There is a really good post at StackOverflow.com called The Hidden Features of C# that asks, "[W]hat are the most hidden features or tricks of c# that even c# fans, addicts, experts barely know?" And lots of the answers provided were unknown to me.
Here are some favorite points:
- Parallel Computing
"Microsoft's Parallel Computing Platform (PCP) team [...] enables the shift to modern, multi- and manycore hardware, by providing a runtime that provides core support for parallelism and resource management, programming models, libraries, and tools that make it easy for developers to construct correct, efficient, maintainable, and scalable parallel programs." - LINQBridge
"With Studio's multi-targeting and LINQBridge, you'll be able to write local (LINQ to Objects) queries using the full power of the C# 3.0 compiler--and yet your programs will require only Framework 2.0."

It made the richer richer and the poor and this country poorer. I willing to listen to you explain how it works.
>The cell phone subsidy program was created by Reagan. "Obamaphones" were a social construct which was created by those who needed a reason to re-elect their president of choice.
THe problem with your explanation is it was mostly a fox news story. the "main stream media" debunked it.
>Perhaps Fox News lied to the "something for nothing" crowd as well?
Well yeah, fox news will lie to anyone willing to listen to them.
Russ, you really need to stop eating the cat nip. "Obamaphone was created during Reagan" - Really? They didn't have these types of cellphones then to give away. Only Doctors and the President had them. The coined phrase for Obamaphone is because he is handing them out like candy. Anyone can get them so long as you can vote Democrat.

Welcome to a new forum for students
Students are constantly being portrayed as apathetic, as blind consumers of bland 'tick a box and yo
By Gemma Tumelty Published 06 November 2006 16:29When I heard the New Statesman was relaunching its website and devoting part of it to campus activism and the issues that affect and inspire students, I was pleased to accept the opportunity to write for it.
Actually scrap that very polite start - not exactly hard-hitting for a radical. Truth is I bloody jumped at the chance. Students are constantly being portrayed as apathetic, as blind consumers of bland 'tick a box and you'll get a job-style higher education' - not to mention maxing out their credit cards when they're not snoozing till midday or stumbling home blind drunk.
Yes ok, some students enjoy a pint or two but there are also active feminists, environmentalists, gay rights campaigners and other politicos. Thousands upon thousands of us joined the call to Make Poverty History, thousands of us form a key part of the anti-war movement and apart from our proud history of social and international campaigning, students have also shown themselves instrumental in taking action on campus-specific issues. Like when Frank Ellis, a lecturer at Leeds university, commented that black people are inferior to white people.
At that point the NUS Anti-Racism/Anti Fascism committee and the student population at Leeds took action. They stood up and fought for his dismissal on the grounds that all students have a right to study in an environment free from discrimination. And their actions had an undeniable impact, with Dr. Ellis being suspended for breach of the Race Relations Act.
Radical canvas?
Time and time again students protest about campus closures, course closures, library closures, halls privatisations and sell offs and in support of our staff - we don't always win, but we always try. These and countless examples of other action go unreported. The point is that students defending resources, standing up to on-campus racism and lobbying the international community are all part of the 'radical' canvas - the activism and ideas that will make this site a cracking read and a sparring ground.
As the president of the NUS and as a former women's officer at Liverpool John Moore's university my personal connection to the concept of campus activism might seem obvious. NUS has traditionally fought for the rights of students and has been the seat of angry student voices through the years, not to mention being the former stomping ground of some rather politically engaged public figures. Jack Straw, Charles Clarke started here as long-haired lefties (whatever went wrong eh?).
Now more than ever NUS is urging students to get active to protect their rights. We think that students need to protect their right to education on the basis of ability not affluence, to protect and promote their rights to demand excellence for their money and to negotiate decent pay and conditions as they enter the seemingly inevitable part time job market to make ends meet. As I'm writing this, ministers are muttering that Muslim students shouldn't wear the veil on campus, and they are proposing that lecturers should 'monitor' students who they suspect of extremism. Protecting our right to expression and fighting to keep our campuses free of the racism, fear and suspicion that flies in the face of civil liberties is part of the brief of the 'radical'.
Anger over top-up fees led thousands onto the streets of London to support the NUS Admission: Impossible campaign. The halcyon days of free education are over. But surely when Tony Blair (who got one of those much yearned after free degrees) made his commitment to 'education, education, education' ten years ago he didn't intend to add a footnote 'for those who can afford it' - which is exactly what his government have instituted with their variable fees.
Make your voices heard
That a market is creeping into the sector, swaying students' choices and creating a crude bums on seats marketing drive by some universities will no doubt take up some room on these pages. That student 'customers' are being gagged by unfair contracts will feature if NUS has anything to do with it. And they are the ones that even get into Higher Education. This year alone there are around 15,000 less students are going to University, our fear is this trend will continue, with some students priced out of education for ever.
Hopefully, what will come out of these pages is an expression of the diversity of student activity and opinion as well as the new challenges that students are facing. The Vietnam war and anti-apartheid marches were easier when education was free and one in five of us weren't in part time jobs. But we still march, lobby and make our voices heard. On this site we'll hopefully hear as much from part-time students, mature students, and students in FE whom the NUS are helping empower to shape their own education. Campus radicals ... bring it on.
1 comment
If one is to maintain that students are undeserving of the pejorative epithets often ascribed to them, then one might seek to offer more convincing evidence than simply claiming 'there are also active feminists, environmentalists, gay rights campaigners and other politicos [on our campuses]'. Indeed, one might suspect that this qualifies as refuting any charge of apathy only to the extent that it would agree with the apparent presumptions of the article of how worthwhile political engagement might manifest itself. After all, there is no recognition of the radical engagement with politics by Muslim extremists in and amongst various Universities in Britain. Whilst disagreeing with their conclusions, it would seem disengenuous to write a piece on political engagement in universities (if that is what this article is truly about) without exploring such an unfortunate state of affairs.
With regard to the NUS, it remains debatable whether it plays any more vital a role within the lives of the majority of its student members than providing them with the means to receive a 10% discount in various bland retail outlets. I am a postgraduate student, and I chose to cancel my NUS membership on a point of principle, that principle being that it simply was not in any sense 'radical' enough. To maintain its incantatory stance regarding top-up fees without ever directing it's no doubt considerable intellect toward the reason why top-up fees are necessary seems a dereliction of duty for any union body that would claim to be acting in the best interests of its members. The answer is certainly not a simple one; but the fact that students with only two 'e' grades at A-level are now accepted in Universities simply means that it would be financially non-viable for any government to offer centrally funded support to all students. This is a shame, and those students who wish to kick on, and remain frustrated, both financially though often academically, by those who treat university as a temporary hedonist purgatory whilst deciding what to job to apply for, might well be justified in asking what the NUS is doing to protect their interests.
Of course, the modern day attitude would be to simplify this into a debate regarding elitist principles in which vocational training is often seen as the poorer brother of the university student. Such simplification is so ignorant as to be dismissed as dishonest. Vocational training is as important as university education, and some are suited to one rather than the other, and no socially motivated value-judgment could be made from one to the other; rather, the imposition of a centrally asserted model of success (to have '50% of school leavers in to University' etc.) is the true prejudice at the heart of the current debate, for it is this that demeans those not-disposed toward University education. Should students wish to get active to enhance their learning environment, then perhaps they could take a little time to reflect and get beyond the emotivist statements offered by those often deemed, usually by their own judgment, to be politically 'radical'.
