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 PUREX process can be modified to make a UREX (URanium EXtraction) process which could be used to save space inside high level nuclear waste disposal sites, such as the Yucca Mountain nuclear waste repository, by removing the uranium which makes up the vast majority of the mass and volume of used fuel and recycling it as reprocessed uranium.
Nuclear Fuel Services, which processes highly enriched uranium for the Navy in Unicoi County, said its plant posed no risk after flooding.
The proposed project would require a 1 million-square-foot nuclear fuel cycle facility to be built. The land would be acquired in three phases over six years at a total cost of nearly $27 million ...
In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide MOX fuels. One of the main method for the separation of spent fuel is the PUREX process, which separates the plutonium and other transuranics from the remainder of the spent fuel. The uranium and plutonium are separated in turn in ...
The last unit of spent nuclear fuel from RBOF was shipped across the site to L Reactor in preparation for RBOF's deactivation. Salt Waste Processing Facility (SWPF) construction began. In 2004, the site shipped its 10,000th drum of transuranic waste to the Waste Isolation Pilot Plant (WIPP), a DOE facility in New Mexico, 12 years ahead of schedule.
The advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
