These were similar to the reactor designs that produced material for nuclear weapons. During that period, the government of the United States also built an experimental molten salt reactor using U fuel, the fissile material created by bombarding thorium with neutrons.

InNobel laureate and discoverer of plutoniumGlenn Seaborgpublicly announced to the Atomic Energy Commissionof which he was chairman, that the thorium-based reactor had been successfully developed and tested.

Inhowever, the US government settled on uranium technology and largely discontinued thorium-related nuclear research. The reasons were that uranium-fueled reactors were more efficient, the research was proven, and thorium's breeding ratio was thought insufficient to produce enough fuel to support development of a commercial nuclear industry.

As Moir and Teller later wrote, "The competition came down to a liquid metal fast breeder reactor LMFBR on the uranium-plutonium cycle and a thermal reactor on the thoriumU cycle, the molten salt breeder reactor.

Thorium-based nuclear power - Wikipedia

But it was apparent to me that my style, my attitude, and my perception of the future were no longer in tune with the powers within the AEC. Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown.

Uranium reactors had already been established, and Hyman Rickoverde 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 Stengerfor one, first learned of it in It came as a surprise to me to learn recently that such an alternative has been available to us since World War II, but not pursued because it lacked weapons applications.

It is therefore an important and potentially viable technology that seems able to contribute to building credible, long-term nuclear energy scenarios. It is difficult to make a practical nuclear bomb from a thorium reactor's byproducts. According to Alvin Radkowskydesigner of the world's first full-scale atomic electric power plant, "a thorium reactor's plutonium production rate would be less than 2 percent of that of a standard reactor, and the plutonium's isotopic content would make it unsuitable for a nuclear detonation.

Separating the uranium from the uranium proved very difficult, although newer laser techniques could facilitate that process.

Other reactors require additional fissile material, such as uranium or plutonium. In addition, the transition to thorium could be done through the incineration of weapons grade plutonium WPu or civilian plutonium. Comparing the amount of thorium needed with coal, Nobel laureate Carlo Rubbia of CERNEuropean Organization for Nuclear Researchestimates that one ton of thorium can produce as much energy as tons of uranium, or 3, tons of coal.

A plug at the bottom of the reactor melts in the event of a power failure or if temperatures exceed a set limit, draining the fuel into an underground tank for safe storage. Thorium's ore monazite generally contains higher concentrations of thorium than the percentage of uranium found in its respective ore.

This makes thorium a more cost efficient and less environmentally damaging fuel source. Thorium mining is also easier and less dangerous than uranium mining, as the mine is an open pit which requires no ventilation, unlike underground uranium mines, where radon levels can be potentially harmful.

Thorium nuclear reactors are unlikely to produce cheaper energy, but the management of spent fuel is likely to be cheaper than for uranium nuclear reactors. The feasibility of reprocessing is still open. This irradiation process may be altered slightly by removing protactinium The irradiation would then make uranium in lieu of uranium, which can be used in nuclear weapons to make thorium into a dual purpose fuel.
