Waste management. Savannah River Laboratory quarterly report, January--March 1975
Glass waste forms were prepared from powdered sludge from high activity waste. Techniques were developed for investigation of the bonding mechanism in concrete waste forms. An improved method was developed for leach testing solid waste forms. Tests determined the effect of feed composition on ion exchange removal of cesium. Laboratory tests indicated that /sup 90/Sr, /sup 238/Pu, /sup 106/Ru (for a few years) and NO/sub 2//sup -/ plus NO/sub 3//sup -/ will be the principal hazardous components in salt solution after removal of /sup 137/Cs. Feasibility was demonstrated of zeolite sorption of cesium from supernate, but the process would increase solids to be stored significantly. Solubility of Pu in simulated waste was studied to determine whether nuclides other than /sup 137/Cs must be removed from plant waste supernate to decontaminate the salt. Thermochemical characterization of the three simulated sludges was completed. Simple water washing was indicated by laboratory tests to classify soil from burial-ground plutonium waste trenches, which average approximately 20 nCi/gram, into two distinct fractions: (1) clay-silt (approximately 60 nCi/gram) that comprises only 1/3 of the total soil that could otherwise require storage in durable containers for eventual transport to a national repository, and (2) sand (approximately 1 nCi/gram), 2/3 of the total soil, that could be returned to the burial trenches. Test data permit estimation of the rate of radiolytic formation of gas from cellulosic containers are sorbent materials contaminated with any radionuclide. Natural vibrational characteristics of a Type III tank were analyzed to determine safe operating frequencies for proposed wiped-film evaporators. Tests indicate that high activity waste in tanks could be solidified in retrievable form by reaction with silica.
