Studies on the effects of direct-coupled ultrasonic energy on dissolution of Type 304 stainless steel in HNO/sub 3/-HCl and of Zircaloy-2 in HNO/sub 3/-HPF/sub 4/ and HNO/sub 3/H/sub 2/SO/sub 4/ solutions were continued, and positive ultrasonic effects were observed with both metals. Ultrasonic treatment of Zircaloy-2 in several molten salts was not fruitful. Although tests of ultrasonic influence on electrolytic dissolution of both metals were essentially negative, they suggest further study. Vibratory treatment at 470 deg C of Th-Bi mixtures effected substantial platelet breakup, the degree of which appeared to depend on treatment time and power level. In tests in which various vibration modes were applied to powdered Fe during compaction, only application in a bell mode produced a positive effect on compact density. Mold fill experiments indicated that appropriate ultrasonic treatment inc reased the amount of metal that could be contained in a die. Preliminary design was completed for an ultrasonic treatment capsule for investigating particle breakup in a UO/sub 2/- NaK system. Studies of ultrasonic control of crystal size during aqueous precipitation of Th(C/sub 2/O/sub 4/)/sub 2/ were undertaken. In initial work with a simulant system of Ca(NO/sub 3/)/sub 2/ and H/sub 2/C/sub 2/O/sub 4/, it was established that oxalate crystals could be prepared in various sizes and possibly smaller than 1 mu . Preliminary study was made of the feasibility of developing an ultrasonic pumping system for circulating core solution in a reactor such as the LAPRE II. Using a simulant sucrose solution, qualitative studies were made of ultrasonic flow characteristics obtained under various conditions. (For preceding period see NYO-7918.) (auth)
