Cyclic process for re-use of waste water generated during the production of UO/sub 2/
Patent
·
OSTI ID:7272014
The process is described whereby waste water produced during the hydrolysis and ammonium hydroxide treatment of UF/sub 6/ to produce ammonium diuranate is recycled for reuse. The solution containing large amounts of ammonia and fluorides and trace amounts of uranium is first treated with lime to precipitate the fluoride. The ammonia is distilled off and recycled to UO/sub 2/F/sub 2/ treatment vessel. The CaF/sub 2/ precipitate is separated by centrifugation and the aqueous portion is passed through cationic exchange beds. (DDA)
