Small Column Ion Exchange Technology at Savannah River Site

The Small Column Ion Exchange (SCIX) system being developed for deployment at the Savannah River Site (SRS) is a supplementary salt waste processing technology that, if implemented, will augment the baseline Salt Waste Processing Facility (SWPF) capability. An opportunity exists to shorten the SRS radioactive waste system lifecycle by 6 years, and significantly reduce life cycle costs, by accelerating salt processing to earlier completion,  simultaneous with sludge vitrification. As described in the Enhanced Tank Waste Strategy, which is part of the Department of Energy (DOE) Office of Environmental Management (EM) Roadmap – EM Journey to Excellence, December 16, 2010, the SCIX system, in combination
with deployment of a Next Generation Solvent in the SWPF, is projected to provide nearly $3B in cost savings due to schedule acceleration and elimination of “salt waste only” processing in the Defense Waste Processing Facility (DWPF).
