WebIn early June 1943, DuPont settled on the bismuth phosphate process in which they dissolved the uranium and plutonium mixture from the cores in acid, and then precipitated out the plutonium by adding bismuth phosphate. The bismuth-phosphate process was used to extract plutonium from irradiated uranium taken from nuclear reactors. It was developed during World War II by Stanley G. Thompson, a chemist working for the Manhattan Project at the University of California, Berkeley. This process was used to produce … See more During World War II, the Allied Manhattan Project attempted to develop the first atomic bombs. One method was to make a bomb using plutonium, which was first produced by deuteron bombardment of uranium in … See more In 1947, experiments began at Hanford on a new REDOX process using methyl isobutyl ketone (codenamed hexone) as the extractant, which was more efficient.

WebBismuth phosphate. The first successflil production method for the separation of Pu from U and its fission products was the bismuth phosphate process, based on the carrying of Pu by a precipitate of BiPO (126). That process has been superseded by Hquid-Hquid extraction (qv) and ion exchange (qv).
