What is Mixed Oxide (MOX) Fuel?

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.
