جداسازی اکسایشی-کاهشی پلوتونیوم و اورانیوم

thumb|upright=1.1|Reprocessing of spent nuclear fuel by the PUREX method, first developed in the 1940s to produce plutonium for nuclear weapons, was demonstrated commercially in Belgium to partially re-fuel a LWR in the 1960s. This aqueous chemical process continues to be used commercially to separate [[reactor grade plutonium (RGPu) for reuse as MOX fuel. It remains controversial, as plutonium can be used to make nuclear weapons.]]
