WebAbstract. An improvement in the bismuth phosphate carrier precipitation process for recovering plutonium is described. It has been found that a more granular and more easily filterable carrier precipitiite is formed if the addition of the bismuth and phosphate ions is effected by first adding 9/10 of the bismuth ions necessary, then slowly adding all of the …
WebFeb 14, 2015 · The bismuth phosphate process was the very first industrial scale method used to recover plutonium from spent fuel [ 2 ], and was employed at the Hanford site from World War 2 through the early 1950s. The waste has been stored in underground tanks at the Hanford site ever since. 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 That process has been superseded by Hquid-Hquid extraction (qv) and ion exchange (qv).
