... is nearing a decision on how to process 30 million gallons of high-level radioactive waste salt solutions at the Savannah River Site in South Carolina to remove strontium, actin~des, and cesium for immobilization in glass and eventual shipment to a geologic repository. The department is sponsoring research and development (R&D)

... · The reliance on a single supplier for CST poses a high schedule nsk. · Technical uncertainties including column plugging, resistance to hydraulic transfer, irreversible desorption, and column system technologies will continue to constitute a high risk for the use of this process for cesium removal.

... CHARGE 3: ASSESS WHETHER THE TECHNICAL UNCERTAINTIES HAVE BEEN SUFFICIENTLY RESOLVED TO PROCEED WITH DOWNSIZING THE LIST OF CANDIDATE PROCESSES This report has focused exclusively on technical issues related to the candidate processes for radionuclide removal Mom high-level waste salt solutions at Savannah River. However, because the final downselection must be based on a number of issues in addition to science and technology, the committee makes no recommendation on which processtes)

From page 4...
... Because the success of this step is essential to all three of the processes for cesium separation, the committee believes that continued R&D on art alternate process to MST for removal of actinides and strontium is essential until MST processing can be demonstrated to meet the saltstone' Defense Waste Processing Facility (DWPF) throughput, and DWPF glass requirements.
