The liquid waste prime contractor at the Department of Energy’s Savannah River Site in South Carolina has finished key construction stages for the latest jumbo-sized Saltstone Disposal Unit (SDU), DOE said Thursday.
The Savannah River Site (SRS) environmental prime Savannah River Mission Completion (SRMC) and its subcontractors have now installed 208 support columns, 25 wall sections and seven segments of roof to complete all concrete construction on SDU-11, DOE said in a press release.
SRMC, a team of BWXT, Amentum and Fluor, manage liquid waste work at SRS. The environmental prime contractor worked with subcontractors Quality Plus Services, US FUSION & Specialty Construction, and DN Tanks.
Once completed and placed in service, SDU-11 will be able to hold more than 33 million gallons of hardened, decontaminated saltstone for onsite disposal at SRS, the 310-square-mile complex located between Aiken, S.C. and Augusta, Ga., according to the release.
“The SDUs provide safe, permanent storage for the decontaminated salt solution from the Salt Waste Processing Facility (SWPF),” said Chuck Comeau, DOE federal project director at SRS. “With SWPF processing at an accelerated rate, it is important to have the SDUs ready for operation. Completing construction milestones ahead of schedule ensures that the SDUs will be ready when needed.”
