RESEARCH AND DEVELOPMENT ACTIVITIES, FIXATION OF RADIOACTIVE RESIDUES QUARTERLY PROGRESS REPORT FOR JULY-SEPTEMBER 1960
continued using simulated high acid Purex wastes. Studies with the fluid bed waste calciner were continued using a feed of simulated high-acid Purex waste; results are described. Results of laboratory-scale-batch calcination studies of simulated Purex-type high-level waste are also discussed. Data from tests to find the effects of variables on calcination of caustic neutralized Purex waste are tabulated; run conditions and resulting powder characteristics are given. Laboratory studies of fixation of high- and lowlevel wastes were extended to include examination of other types of waste and experiments with new varieties of absorption media. High-level studies conducted with clear supernatant fluids indicate the possibility of a simple fixation process that may be applicable to many types of waste. Cation exchange properties of clinoptilolite and natural zeolites were compared for cesium selectivity. Micro plant tests made by passing Purex tank-farm condensate waste through ion-exchange materials are reported. Results are listed for clinoptilolite, synthetic apatite, and alumino-silicate ion exchangers. (For preceding period see HW- 66571.) (J.R.D.)
