Thorium as a nuclear fuel - ENSTERNA

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 materialb. In this regard it is similar to uranium-238 (which transmutes to plutonium-239). All thorium fuel concepts therefore … Thorium as a nuclear …
