    Although thorium232 is not itself a nuclear reactor fuel since it will not sustain a chain reaction, it may be converted into the fissionable fuel uranium233, but uranium233 has not proven to be a practical alternative to natural uranium. Thorium232 can react with a thermal (slow) neutron to form thorium233, emitting a gamma ray.

    The thorium fuel cycle is the path that thorium transmutes through from fertile source fuel to uranium fuel ready for absorbs a neutron, transmuting it into Th233. Th233 beta decays to Pa233 and finally undergoes a second beta minus decay to become U233. This is the one way of turning natural and abundant Th232 into something fissionable.
