The basic technology for manufacturing the MOX fuel pellets was developed by TVEL subsidiary AA Bochvar Research Institute of Inorganic Materials.

When MOX fuel is loaded into a LWR and burned for four years, only part of the plutonium is consumed. 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-

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. 2021-02-04 · Rosenergoatom said the move to MOX fuel at Beloyarsk-4 brings the Russian nuclear industry “one step closer” to its goal of closing the fuel cycle. It said that for the first time during a planned outrage, which began on 8 January 2021 and concluded this week, only MOX fuel was loaded into the reactor. fuel, are seriously considered as a future technology.

Source: World Nuclear Association Nuclear Fuel Report 2019, Table 8.7, updated. MOX fuel. Mixed uranium oxide + plutonium oxide (MOX) fuel has been used in about 30 light-water power reactors in Europe and about ten in Japan. It consists of depleted uranium (about 0.2% U-235), large amounts of which are left over from the enrichment of uranium, and plutonium oxide that derives from the chemical processing of used nuclear fuel (at a reprocessing plant).

Mixed Oxide (MOX) fuels, a traditional way to achieve this is to evaluate both fuels on the deterministic premise that the fuel will be sent to geologic disposal once spent. This methodology often leads to higher costs for cycles using MOX fuel. Geologic disposal is not the sole possible ending for spent Light Water Reactor (LWR) fuel. In addition, JNFL engages in uranium enrichment, temporary storage of vitrified waste, and disposal of low-level radioactive waste.

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.
