Note

Especially designed or prepared systems for the conversion of UF 6 to UO 2 EXPLANATORY NOTE Conversion of UF 6 to UO 2 can be performed by one of three processes. In the first, UF 6 is reduced and hydrolyzed to UO 2 using hydrogen and steam. In the second, UF 6 is hydrolyzed by solution in water, ammonia is added to precipitate ammonium diuranate, and the diuranate is reduced to UO 2 with hydrogen at 820 °C. In the third process, gaseous UF 6 , CO 2 , and NH 3 are combined in water, precipitating ammonium uranyl carbonate. The ammonium uranyl carbonate is combined with steam and hydrogen at 500-600 °C to yield UO 2 . UF 6 to UO 2 conversion is often performed as the first stage of a fuel fabrication plant.
