Title: RESEARCH AND DEVELOPMENT ACTIVITIES--FIXATION OF RADIOACTIVE RESIDUES. Quarterly Progress Report, October-December 1962

Abstract

A radiant-heat calciner and melt-pot calciner were used to process full- level Purex 1 WW in continued experimental studies. Sugar was found to have a suppressing effect on Ru volatility. Continued development work is reported on in-tank solidification of bulk salt waste and packaging of radiocesium and ratiostrontium concentrates. In sorption and extraction studies, a part of the ternary equilibrium system Cs-- H--Na was determined for clinoptilolite. The effects of temperature on mass action quotients were evaluated for the Cs--Na system for seven zeolites. Two additional runs were made in a micro pilot plant with Purex condensate to evaluate mixed ion exchange decontamination. The effects of particle size, flow rate, and temperature on Sr adsorption by Linde 4A zeolite were studied. Loading rates are significantiy increased at elevated temperatures without capacity loss. Developmental studies were continued toward use of D2EHPA solvent extraction flowsheet for removal of Sr and rare earths from Purex FTW. (J.R.D.)
