JNFL also has plans to construct a MOX fuel fabrication plant to open in the first half of 2019. Outline of JNFL's Nuclear Fuel Cycle Facilities. What is mixed oxide (MOX) fuel? The mixed oxide fuel proposed by Shaw AREVA MOX Services (formerly Duke COGEMA Stone & Webster (DCS)) is a blend of plutonium dioxide and depleted uranium dioxide that will be used as fuel in commercial nuclear power plants. Depleted uranium is a byproduct of the uranium enrichment process.

Update on Japan's Nuclear Energy Development and Spent Fuel

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. See Figure 4.1. In the closed fuel cycle today, the spent fuel discharged from the reactor is reprocessed, and the products are partitioned into uranium (U) and plutonium (Pu) suitable for fabrication into oxide fuel or mixed oxide fuel (MOX) for recycle back into a reactor.

If it is reprocessed, this multi-recycle plutonium becomes a burden on the LWRs, because spent MOX fuel has a larger fraction of non- up operation and MOX-LWR on fuel cycle performance is discussed with respect to waste management, and potential performance improvements, i.e., a reduction in the number of glass units, are proposed. In the present study we do not consider FBR fuel cycle systems since they are inherently more complex and present additional options that must be MOX-bränsle (från engelskans mixed oxide, blandad oxid) är en typ av upparbetat kärnbränsle.

Mox fuel cycle

2020-02-20 · The uncertain fate of the spent mixed-oxide (MOX) fuel removed from two nuclear power reactors in western Japan last month — for the first time since the commercial use of plutonium-uranium fuel in teristics of a particular fuel cycle against how well it meets the criteria we have adopted. Our analysis separates fuel cycles into two classes: “open” and “closed.” In the open or once-through fuel cycle, the spent fuel discharged from the reactor is treated as waste. See Figure 4.1.

The nuclear fuel recycling process involves converting spent plutonium, formed in nuclear power reactors as a by-product of burning uranium fuel, and uranium into a “mixed oxide” (MOX) that can be reused in nuclear power plants to produce more electricity.
