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. Commercial nuclear fuel fabrication consists of three major processes: conversion (of the uranium hexafluoride into uranium dioxide powder), ceramic (production of ceramic uranium dioxide pellets from the powder), and mechanical (loading of the pellets into fuel rods and assemblies). The GKhK plant is Russia’s leading full nuclear fuel cycle complex, processing nuclear waste from power generating nuclear reactors to establish future nuclear fuel ring closure. MOX-fuel for previous versions of fast breeder reactors in the USSR and Russia had limited production at Russia’s oldest Mayak nuclear processing facility.

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. MOX fuel is on the long-term lower than the radiotoxicity of the plutonium that would have not been used in MOX plus the uranium fuel which would have been used in place of MOX. 6.

Information from the World Nuclear Association, the global organization that provides information on nuclear power, nuclear energy, nuclear fuel, MOX production and other nuclear fuel cycle aspects. MOX fuel tends to run hotter because of lower thermal conductivity, which may be an issue in some reactor designs.

M.Sc.Thesis: Spent nuclear fuel reprocessing technology

About 96% of spent fuel is uranium and up to 1% is plutonium. These materials are valuable resources and both can be recycled as MOX fuel, saving 10 to 20% of the natural uranium in the nuclear fuel cycle with light water reactors. MOX Fuel Use in light water reactor (LWR) The recovered plutonium at the reprocessing plant is ready to be re-introduced into the nuclear power plants in the form known as uranium-plutonium mixed oxide (MOX) fuel. Japan's electric power companies aim to utilize MOX fuel in 16 to 18 nuclear reactors. MOX Fuel Use in light water reactor (LWR) 2021-02-04 Unit 4 of the Beloyarsk nuclear power plant in Russia will be completely switched to uranium-plutonium MOX fuel in 2022, marking an important step towards closing the nuclear fuel cycle, Russia’s Rosatom has announced.
