Description

Continuous dissolution of 2% U-- Zr alloy fuel in a laboratory-scale Ti dissolver was demonstrated using refluxing 3 M HNO/sub 3/--1.2 M HF--0.4 M HBF/ sub 4/--0.6 M Cr(III)0.4 M Cr(VI)--0.46 M Zr as the dissolvent. Dissolution rates and solution corrosion rates were 8 to 16 mg/cm/sup 2/min and approximates 1 mil/month, respectively. Reagent was added to the dissolver at the rate needed to maintain the potential measured by a Au vs. calomel electrode in the product effluent as close to a preselected standard value as possible.
