PILOT PLANT STUDIES OF CONTINUOUS NITRIC ACID DISSOLUTION OF URANIUM- ALUMINUM ALLOY
Technical Report
·
OSTI ID:4762659
Pilot plant studies were made of the continuous nitric acid dissolution of 7.5% uranium-92.5% aluminum alloy slugs. Seventy-two runs were completed in a two-inch diameter by fifteen-foot high glass-pipe dissolver. Maximum dissolution rates achieved were about 1.0 kg uranium per day from cast alloy, and 1.5 kg uranium per day from extruded alloy, per square inch of dissolver cross-section. The optimum feed acid concentration was about 5M. The feasibility of continuous upflow dissolution of uraniumaluminum slugs in a flooded dissolver was proven and preliminary data for the design of a plant-scale dissolver were obtained. (auth)
