AN AQUA REGIA FLOWSHEET FOR URANIUM DISSOLUTION
Technical Report
·
OSTI ID:4160825
A dilute aqua regia flowsheet for the complete dissolution of solid uranium slugs in 7.5 hours is shown. Before the dissolver product solution can be further prooessed in stainiess steel equipment, the chloride must be removed. Two flowsheets for chloride removal are presented. In the first flowsheet, the chloride is removed by volatilization and in the second, by oxidation. The chloride removal need not be carried out in the dissolver vessel. The larger safe batch sizes of a homogeneous system may permit combining several batches from the heterogeneous dissolver system before chloride removal. Titanium, Haynes 25, and Hastelloy F are possible materials of construction for the process equipment that is to contain both nitric and hydrochloric acids. (auth)
