  • Nuclear reprocessing - Wikipedia

    Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors.

  • What is Nuclear Recycling?

    Nuclear TransformationsNuclear Fuel CyclesAdditional ReadingBefore you go on, recall that Uranium exists in nature as 2 isotopes: the less common U-235, and the more common U-238.Conventional reactors mainly split U-235 to produce power, and the U-238 is often considereduseless. When a standard reactor runs low on U-235, it must be refueled, even though there is a lotof U-238 still in there. A common type of nuclear reaction is called beta-decay. When a nucleus has more neutrons than itwould like to have, it often beta-decays by breaking a neutron into a proton and an electron. Theelectron (called a beta-particle in this case, since it originated in the nucleus) flies off intonature, and the main result seen in the nucleus is a neutron converting to a proton (see figure). When U-238 absorbs a neutron in a nuclear reactor, it becomes U-239, which is just the isotope ofUranium with one extra neutron than U-238. This beta-decays quickly and becomes Np-239. Then, theNp-239 beta-decays again to become Pu-239, which is a fissile isotope that can p...

Here the ‘ore’ (or effectively the concentrate from it) is hard ceramic uranium oxide with an array of other elements (about 4% in total), including both fission products and actinides formed in the reactor. There are three broad kinds of metallurgical treatment at metal smelters and refineries: 1. Pyrometallugy using heat to initiate separation of the metals from their mineral concentrate (e.g.copper smelting to produce blister copper, lead smelting). 2. Electrometallurgy using electric current to separate the metals (e.g.alumina smelting to produce aluminium). 3. Hydrometallurgy using aqueous solutions that dissolve the metal, with sometimes also electrolytic cells to separate them (e.g.zinc production, copper refining). The main historic and current process is Purex, a hydrometallurgical process. The main prospective ones are electrometal...
