Thorium

Thorium is the base fuel for a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material. 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. The Thorium Patent Forecast® includes patents for all parts of the process necessary for a thorium reactor to operate, from reactor design to fuel mining and processing, to reactivity moderators, to alloys for manufacturing component parts.
