By using the reprocessed plutonium, the utilization efficiency of uranium, which is defined as the mass of uranium consumed duo to per kilowatt hour electricity production, is significantly increased. The process for uranium-plutonium mixed oxide (MOX) fuel fabrication is essentially the same – notwithstanding some specific features associated with handling the plutonium component. Figure 1: The closed nuclear fuel cycle, showing primary and recycled materials flow through fuel cycle, the spent fuel discharged from the reactor is treated as waste.

Geologic disposal is not the sole possible ending for spent Light Water Reactor (LWR) fuel.

Japan reprocesses spent fuel, instead of disposing it as waste, to extract plutonium and uranium to make MOX fuel for reuse, while the U.S. discontinued the costly and challenging program.

The breeder fuel cycle produces a large plutonium surplus which can be used to produce nuclear weapons or produce more MOX to allow your nuclear industry to expand more rapidly than waiting for U-235 to trickle out of your centrifuges.

The remainder can either be disposed as unprocessed spent fuel or reprocessed for further recycles. If it is reprocessed, this multi-recycle plutonium becomes a burden on the LWRs, because spent MOX fuel has a larger fraction of non- The closed fuel cycle strategy , along with reprocessing and MOX recycling, enables today, with existing facilities : •Stabilization of spent fuel quantity : with respect to underwater storage capacity MOX-bränsle (från engelskans mixed oxide, blandad oxid) är en typ av upparbetat kärnbränsle.

Nevertheless, the reviewers An economic analysis has been performed to compare four nuclear fuel cycle options: a once-through cycle (OT), DUPIC recycling, thermal recycling using MOX fuel in a pressurized water reactor (PWR-MOX), and sodium fast reactor recycling employing pyroprocessing (Pyro-SFR). This comparison was made to suggest an economic competitive fuel cycle for the Republic of Korea.
