When compared with UOX FAs, MOX FAs have the following features that are relevant to transport and storage. the fission and absorption cross sections for plutonium isotopes are substantially different than those for 235U. MOX fuel is more radioactive.

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.

No technical obstacles have been identified, From the viewpoint of waste management, a quantitative evaluation of LWR nuclear fuel cycle system performance was carried out, considering both higher burn-up operation of UO 2 fuel coupled with the introduction of MOX fuel. A major parameter to quantify this performance is the number of high-level waste (HLW) glass units generated per GWd (gigawatt-day based on reactor thermal power Japan Nuclear Fuel Ltd. （JNFL）applied for the approval of nuclear fuel material processing to construct the MOX fuel processing facility for light water reactor （LWR）“J-MOX”at Rokkasyo-mura, Aomori Pref. in April 2005.

In addition, JNFL engages in uranium enrichment, temporary storage of vitrified waste, and disposal of low-level radioactive waste. 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. 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.

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. 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). In addition, JNFL engages in uranium enrichment, temporary storage of vitrified waste, and disposal of low-level radioactive waste. JNFL also has plans to construct a MOX fuel fabrication plant to open in the first half of 2019.
