Thorium: Reduce, Reuse, Recycle Energy From Thorium

Thorium, with an atomic mass of 232, begins the nuclear energy generation process at least five neutron absorptions removed from the first transuranic isotope that could be generated. As previously mentioned, thorium-232 absorbs a neutron, transmuting to protactinium-233 and then uranium-233, which is fissile.
