WebJul 7, 2011 · The control chamber can halt the fission reaction quickly in a LFTR because it takes a month to generate new uranium fuel from thorium atoms, and LFTRs cannot generate run-away heat production. Had the nuclear reactors at Fukushima been LFTRs, the whole crisis would have been avoided. WebFission of thorium creates long-lived fission products including technetium-99 (half-life of over 200,000 years). Without reprocessing, thorium-232 is itself extremely long-lived (half-life of 14 billion years) and its decay products will build up over time in irradiated fuel. how to retrieve wireless password

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, Th , as the fertile material. In the reactor, Th is transmuted into the fissile artificial uranium isotope U which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as Th ), which are … See more Concerns about the limits of worldwide uranium resources motivated initial interest in the thorium fuel cycle. It was envisioned that as uranium reserves were depleted, thorium would supplement uranium as a fertile … See more As a fertile material thorium is similar to U , the major part of natural and depleted uranium. The thermal neutron absorption cross section (σa) and resonance integral (average of neutron cross sections over intermediate neutron energies) for Th are about three and one … See more Nuclear technology portal Energy portal • Thorium • Thorium-232 • Occurrence of thorium See more • International Thorium Energy Committee See more In the thorium cycle, fuel is formed when Th captures a neutron (whether in a fast reactor or thermal reactor) to become Th . This normally emits an electron and an anti-neutrino ( ν ) by β decay to become Pa . This then emits another electron and anti-neutrino by a … See more Thorium fuels have fueled several different reactor types, including light water reactors, heavy water reactors, high temperature gas reactors, sodium-cooled fast reactors, and See more • Kasten, P.
