SUMMARY The suggestionwas made that the introductionof ultrasoundinto Tank I01-SY might serve to release the hydrogen bubbles trapped in the slurry.

Two major considerationswere I) the method for deliveringthe energy into the slurry and 2) the effectivevolume of action. In this study, we attacked the former by designing and testing a liquid-filled waveguide and radiator,and the latter by making ultrasonicproperty measurementson syntheticwaste. Our conclusionis that ultrasonicmitigation may not be feasible,primarilybecause of the very high attenuation(1000 to 5000 dB/m) factor at 10 to 30 kHz. Such a high attenuationwould restrict the action volume to such a low value as to make the method impractical. Further investigationsare recommendedto identifythe cause of this effect and determine if this same effect will be seen in real I01-SY waste.
