How do nuclear reactors work.
Thorium as a nuclear fuel. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is ‘fertile’ and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium ...
