  2. PUREX - Wikipedia

    en.wikipedia.org/wiki/PUREX

    The PUREX process was invented by Herbert H. Anderson and Larned B. Asprey at the Metallurgical Laboratory at the University of Chicago, as part of the Manhattan Project under Glenn T. Seaborg; their patent "Solvent Extraction Process for Plutonium" filed in 1947, [14] mentions tributyl phosphate as the major reactant which accomplishes the ...

  3. Nuclear reprocessing - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reprocessing

    The UREX process is a PUREX process which has been modified to prevent the plutonium from being extracted. This can be done by adding a plutonium reductant before the first metal extraction step. In the UREX process, ~99.9% of the uranium and >95% of technetium are separated from each other and the other fission products and actinides.

  4. Advanced reprocessing of spent nuclear fuel - Wikipedia

    en.wikipedia.org/wiki/Advanced_reprocessing_of...

    The first reprocessing approach is based on the PUREX (Plutonium Uranium Reduction EXtraction) process, which is the standard and mature technology applied worldwide to recover uranium and plutonium from spent nuclear fuel at industrial scale. Following the dissolution of the spent fuel in nitric acid and the removal of uranium and plutonium ...

  5. Herbert H. Anderson - Wikipedia

    en.wikipedia.org/wiki/Herbert_H._Anderson

    Herbert H. Anderson (1913 – 2001) [1] [2] was an American organic chemist, a member of Glenn Seaborg's Met Lab group at Chicago during the Manhattan Project. [3] Anderson was a co-inventor, with Larned B. Asprey, of the PUREX process for plutonium and uranium extraction.

  6. Purex (laundry detergent) - Wikipedia

    en.wikipedia.org/wiki/Purex_(Laundry_detergent)

    Purex is a brand of laundry detergent and laundry-related products manufactured by Henkel North American Consumer Goods and marketed in the United States and Canada. Purex is one of the most widely used laundry detergents in North America. Its original product, Purex Bleach, was a major competitor to Clorox bleach.

  7. Actinide chemistry - Wikipedia

    en.wikipedia.org/wiki/Actinide_chemistry

    The current method of choice is to use the PUREX liquid–liquid extraction process which uses a tributyl phosphate/hydrocarbon mixture to extract both uranium and plutonium from nitric acid. This extraction is of the nitrate salts and is classed as being of a solvation mechanism. For example, the extraction of plutonium by an extraction agent ...

  9. Hot cell - Wikipedia

    en.wikipedia.org/wiki/Hot_cell

    This type of hot cell is used purely for production of radiopharmaceuticals. A chemistry unit is placed in each cell, the production process is initiated (receiving the radioactive 18 F from the cyclotron) and once finished, the cells are left closed for a minimum of 6 hours allowing the radiation to decrease to a safe level. No manipulation is ...
