Description/Abstract:
PENETRATION RATES OF TH METAL BY BOILING HNO3 WERE MEASURED AS A FUNCTION OF THE CONCENTRATION OF FLUORIDE CATALYST AND OF HNO3. DISSOLVED TH AND AL WERE FOUND TO INHIBIT THE REACTION. THORIA EXHIBITED PENETRATION RATES MUCH LOWER THAN THOSE OF TH METAL. IN ADDITION TO SPECIFIC RATE MEASURMENTS, POT TYPE BATCH DISSOLVINGS WERE CARRIED OUT TO ESTIMATE PLANT TIME CYCLES. AN EMPIRICAL MATHEMATICAL EQUATION WAS DEVISED WHICH CORRELATES RESULTS OF THESE BATCH DISSOLVINGS AND FACILITATES APPLICATION OF THE DATA TO OTHER TYPES OF DISSOLVERS.
