Thorium fuel cycle Wikipedia

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium 232 Th as the fertile material In the reactor 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel Unlike natural uranium natural thorium contains only trace amounts of fissile material such as 231 Th which are insufficient to initiate a nuclear chain reaction
