WebFeb 16, 2012 · The Thing about Thorium Thorium's advantages start from the moment it is mined and purified, in that all but a trace of naturally occurring thorium is Th232, the … The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, Th , as the fertile material. In the reactor, Th is transmuted into the fissile artificial uranium isotope U which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as Th ), which are insufficient to initiate a nuclear chain reaction. Additional fissile material or an…

WebThe irradiated fuel can then be unloaded from the reactor, the U-233 separated from the thorium, and fed back into another reactor as part of a closed fuel cycle.
