PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel ( spent nuclear fuel , or irradiated nuclear fuel).

The First generation Plant was then converted into a pre-handling plant for Magnox reprocessing and was recommissioned in 1969. In 1973, after both plants had been shut down for one year for maintenance, a violent reaction called a "blowback" occurred in the First Generation Plant which contaminated that plant and 34 workers with ruthenium -106.
It is also used in nuclear reprocessing as part of the PUREX process. A 15–40% (usually about 30%) solution of tributyl phosphate in kerosene or dodecane is used in the liquid–liquid extraction (solvent extraction) of uranium, plutonium, and thorium from spent uranium nuclear fuel rods dissolved in nitric acid. Liquid extraction can also be ...
If yes, should the reprocessing plant be about double the estimated site required to handle United Kingdom oxide fuels and be used as to the spare capacity, for reprocessing foreign fuels? The result of the inquiry was that the new plant, the Thermal Oxide Reprocessing Plant, was given the go-ahead in 1978. [3]
As is typically found in civilian European thermal reactors, a 5.3% plutonium MOX fuel-bundle, produced by conventional wet-chemical/PUREX reprocessing of an initial fuel assembly that generated 33 GWd/t before becoming spent nuclear fuel, creates, when it itself is burnt in the thermal reactor, a spent nuclear fuel with a plutonium isotopic ...
