Abstract

1356766 Oxide purification RBG REAKTORBRENNELEMENTE GmbH 24 April 1972 [1 June 1971] 18962/72 Heading C1A The fluoride content of powdered oxides of nuclear fuel elements is reduced by pyrohydrolysis with steam in the absence of H 2 . The oxide is preferably UO 2 formed by reduction of UO 3 with H 2 , and the pyrohydrolysis may be carried out in the same reactor as reduction or in a separate reactor. The preferred temperature is greater than 650‹ C., e.g. 680‹ C., and the final F content may be less than 25 p.p.m.
