Title: Long-Term High-Level Defense-Waste technology. Progress report, April-June 1982

Technical Report ·
OSTI ID:6749183

This report summarizes the work accomplished during the third quarter of Fiscal Year 1982. Two major technology tasks are supported within Rockwell Hanford Operations (Rockwell): residual liquid solidification and in situ drying. In addition, Rockwell is providing technical guidance for waste tank and cesium capsule corrosion tests being performed at Battelle Pacific Northwest Laboratory (PNL) and pass-through funded concrete grout bulk waste immobilization studies at Oak Ridge National Laboratory (ORNL). In the residual liquid solidification effort, the primary alternative studied this year is the wiped-film evaporator (WFE) approach to solidifying salt well pumped liquids and returning the molten material to single-shell tanks for microwave final stabilization to a hard dry product. Both systems analysis and experimental work are proceeding to evaluate this approach. The primary alternative for in situ stabilization of in-tank wastes is microwave drying of wet salt cake and unpumped sludges. Experimental work has been successfully conducted on a 1/12 scale tank containing wet synthetic salt cake. Related systems analysis of a full-scale system has been initiated.
