With the placement of 25 wall sections, 208 support columns, and 7 roof sections, work crews have completed all major concrete placements for the megavolume Saltstone Disposal Unit (SDU) 10 at the Savannah River Site in South Carolina, according to the Department of Energy’s Office of Environmental Management.

The Department of Energy’s Office of Environmental Management is responsible for roughly 90 million gallons of radioactive liquid waste at Idaho National Laboratory, the Hanford Site in Washington state, and the Savannah River Site in South Carolina. About 900,000 gallons of waste are stored at INL, 56 million gallons at Hanford, and roughly 36 million at SRS. A further 400,000 gallons of waste from various operations are being stored at the Oak Ridge Site in Tennessee.

Savannah River Mission Completion (SRMC), the radioactive liquid waste contractor at the Department of Energy’s Savannah River Site, is optimizing some equipment maintenance at the Salt Waste Processing Facility (SWPF). The facility traditionally uses centrifugal contactors in the solvent extraction process, and its laboratory uses manipulators to handle process samples and equipment within its radioactive cell. The equipment requires periodic maintenance and rebuilding.
