Thorium Reactors: A Promising Future for Sustainable Nuclear Energy
In a Thorium Reactor thorium-232 (Th-232) is used in place of uranium-235 (U-235) or plutonium-239 (Pu-239) as the fertile material. When bombarded by neutrons in a nuclear reactor, Th-232 absorbs a neutron and transmutes into uranium-233 (U-233). U-233 is then fissile, meaning it can sustain a nuclear chain reaction. The reaction is initiated using a core of fissile uranium or plutonium to produce the first neutrons, which cause the fertile thorium to transmute.
