Patent ID: 7063823

Claim:
A depleted UF 6 processing plant comprising: a first fluidized bed reactor configured to react depleted UF 6 with steam to produce UO 2 F 2 and hydrogen fluoride; a second fluidized bed reactor connected to the first fluidized bed reactor and configured to react the UO 2 F 2 with steam to produce U 3 O 8 , hydrogen fluoride and oxygen; a gas cooler configured to cool the hydrogen fluoride generated in the first and second fluidized bed reactors down to 150 to 300° C.; and a fluorine fixing reactor containing granular calcium carbonate and connected to the gas cooler to receive the hydrogen fluoride cooled down to 150 to 300° C. from the gas cooler, the fluorine fixing reactor configured to form granular calcium fluoride from the granular calcium carbonate and the hydrogen fluoride passing through the fluorine fixing reactor.
