During the fuel burning, thorium 232 transforms into a fissile uranium 233. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as thorium 231), which are insufficient to initiate and sustain the nuclear chain reaction. Therefore, additional fissile material is necessary to initiate the fuel cycle.
