FIXATION OF RADIOACTIVE RESIDUES. Quarterly Progress Report, January- March 1961
Research and development activities in the field of fixation of radioactive wastes are reported. Calcination studies of simulated Purex high- level waste solutions by the batch method were continued on the bench scale. Melting of the calcine was studied with emphasis on the effects of the relative concentrations of metal ions in the waste solution. Batch calcination in annular pots using induction heating was demonstrated as was a procedure for removing the calcines for rework. A general equation was developed relating temperatures in proposed cylindrical and annular cylindrical containers full of high-activity- level calcined waste with other parameters of vessel size, heat generation rates, coolant temperatures, calcine thermal conductivity, and vessel-coolant heat transfer rates. Laboratory investigations of mineral reactions for the solid fixation of radioisotopes from wastes were continued. Studies were made of adsorbers, elution of mineral beds, evaluation of adsorption variables, and new mineral reactions. The decontamination abilities of clinoptilolite and organic ion exchange resins were explored. (M.C.G.)
