Summary

Further investigation of mercury disintegration of fuel-element cladding; materials under ultrasonic influence revealed a measurable rate of ultrasonic attack for Zircaloy-2, corresponding with previously obtained results with Type 304 stainless steel. Ultrasonic attack rates on thorium in mercury at 72 d to 88 d C ranged to 6.92 mg/cm/sup 2/hr under the experimental conditions used. Ultrasonic application produced a positive and significant effect on the flow of thixotropic thorium amalgam through an orifice, the rate of flow being markedly increased with modest increase in ultrasonic power. From experimentation to date, it appears that ultrasonic agglomeration supplemerted by the use of additive liquid aerosol particles can achieve sufficient decontamination in calciner off-gas to materially reduce the health hazard. Using a solid KCl simulant aerosol, a reference was established for evaluating improvements in operatiag techniques, and test data Indicate that collection efficiency improves with large volumes of additive aerosol, low flow rates, and a relatively low ultrasonic frequency. Studies of ultrasonic coalescence in stabilized kerosene/water emulsions, using apparatus permitting the development of annular standing waves, indicated effective emulsion breaking on a continuous basis at flow rates in the range of 144 to 360 cc/min. The annular geometry apparently leads to superior results through minimization of circulation effects. (auth)
