OSTI.GOV Conference: An Assessment of the Attractiveness of Material Associated with a MOX Fuel Cycle from a Safeguards Perspective Japan Nuclear Fuel Limited (JNFL) is operating a nuclear fuel cycle business in Rokkasho village of Aomori Prefecture. So far, a uranium enrichment plant, a low-level radioactive waste burial center, and a high-level radioactive waste storage and management center have begun operations. Fuel cycles have always been of key strategic importance to the nuclear industry to form MOX fuel, which can be effectively utilized in CANDU.

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- Stage 1: recycle used LWR-MOX a few FR needed (3 – 5 GWe?)

Learning Outcomes MOX and Th fuel. To get a global understanding of the utilization of Pu and Th based fuel in light water reactors: Involvement of the large stock of depleted uranium and bred plutonium into the fuel cycle would enable expansion of the resource base of nuclear power industry and reduction of natural uranium consumption,’ commented Konstantin Vergazov, Head of the industrial working group for reaching the projected indicators in MOX fuel production, Senior Vice President of TVEL JSC for R&D, technology and MOX: the first step in recycling.

Learning Outcomes MOX and Th fuel. To get a global understanding of the utilization of Pu and Th based fuel in light water reactors: Energy of MOX fuel is equivalent to 4% U-235 enriched uranium oxide fuel. The plutonium content of MOX fuel produced in JNFL’s MOX Fuel Fabrication Plant varies from around 4 to 9% depending on the design of the fuel. The MOX Fuel Fabrication Plant properly maintains necessary measures for Safety, Safeguards and Security.

Update on Japan's Nuclear Energy Development and Spent Fuel

Fuel cycle strategies to optimize the MOX in reactors Marc Arslan*, Isabelle Leboucher, Erwan Bouvier AREVA NC – 33 rue La Fayette – F-75442 Paris cedex 9 - France Abstract 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.

MOX-bränsle – Wikipedia

Mixed oxide fuel, commonly referred to as MOX fuel, is nuclear fuel that contains more than one oxide of fissile material, usually consisting of plutonium blended with natural uranium, reprocessed uranium, or depleted uranium. MOX fuel is an alternative to the low-enriched uranium fuel used in the light water reactors that predominate nuclear power generation. For example, a mixture of 7% plutonium and 93% natural uranium reacts similarly, although not identically, to LEU fuel.
