Fifth Mega Saltstone Disposal Unit Approved for Operation at U.S. Savannah River Site
The U.S. Department of Energy Office of Environmental Management announced on August 25 that it has approved the operation of the fifth mega saltstone disposal unit at the Savannah River Site in Aiken, South Carolina. Designated as SDU 10, the facility will receive purified material for final disposal, marking a new milestone in the site's cleanup program. According to reports, SDU 10 completed construction in June 2024, nearly 10 months ahead of schedule. Its leak-tightness testing was completed in December 2025, and the test results verified that the unit can safely store up to 33 million gallons of purified, solidified salt solution generated at the Savannah River Site. Saltstone disposal units are the end-stage facilities in the salt waste treatment process.
