PUREX (plutonium uranium reduction extraction) is a chemistry, chemical method used to purify fuel for nuclear reactors or nuclear weapons. 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). It is based on liquid–liquid extraction ion-exchange. PUREX is applied to spent nuclear fuel, which consists primarily of very high atomic weight, atomic-weight (actinoid or "actinide") chemical element, elements (e.g. uranium, plutonium, americium) along with smaller amounts of material composed of lighter atoms, notably the fission products produced by reactor operation. The actinoid elements in this case consist primarily of the unconsumed remains of the original fuel (typically U-235, Uranium-238, U-238, and/or Pu-239).
