The lead ... Thorium may be three times more abundant on Earth than uranium, it is difficult to estimate, and can also be used in nuclear reactors. In addition, thorium and uranium deposits do not necessarily occur at the same places, thus countries with large potential uranium resources may well have very little thorium and vice-versa. 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. [31] Disadvantages [ edit] Some experts note possible specific disadvantages of thorium nuclear power: Breeding in a thermal neutron spectrum is slow and requires extensive reprocessing.Although thorium advocates say that thorium reactors produce little radioactive waste, they simply produce a different spectrum of waste to those from uranium-235. This still includes many dangerous alpha and beta emitters, and isotopes with extremely long half-lives, including iodine-129 (half-life of 15.7 million years).Today, thorium is seen by some as a thousand year solution to energy and environmental problems, but one that is offset by high start-up costs and a number of technical hurdles.

Nov 03, 2019 · The DOE Office of Environmental Management now considers the disposal of this uranium-233 to be ‘an unfunded mandate’. Thorium reactors also produce uranium-232, which decays to an extremely potent high-energy gamma emitter that can penetrate through one metre of concrete, making the handling of this spent nuclear fuel extraordinarily dangerous. Still, in real reactors, the content of fertile thorium 232 also decreases, and fission products with significant absorption cross-section accumulate in the fuel as fuel burnup increases. The fertile-to-fissile conversion characteristics depend on the fuel cycle and the neutron energy spectrum.17 hours ago · Molten salt reactors’ early history.
