Thorium is the base fuel for a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material. In a thorium-fueled reactor, 232 Th absorbs neutrons to produce 233 U, which fissions and releases energy. This thorium fuel cycle has several potential advantages over a uranium fuel cycle, including thorium's greater abundance, superior physical and nuclear properties, reduced plutonium and actinide production, and better resistance to nuclear weapons proliferation when used in certain reactors.
