WebWhen thorium is used as a nuclear fuel, much less plutonium and other minor transuranics (e.g., Np, Am, Cm) are produced than are produced in uranium fuel cycles. The reduced production of transuranics occurs for two reasons. First, the fissile product of 232 Th is 233 U, further in the actinide series from plutonium and the minor actinides.
