  • Uranium Fuel CycleNuclear Power

    Nuclear Fuel Cycle. Source Nuclear Regulatory Commission from US. License CC BY 2.0. The uranium fuel cycle is a process chain consisting of a series of differing stages. Uranium fuel cycle uses an enriched uranium fuel ( 4 of U-235) as a fresh fuel.During the fuel burning the content of the U-235 decreases and the content of the plutonium increases (up to 1 of Pu ).
