The assistant secretary of energy and other dignitaries will be in Aiken today to celebrate the closure of Tank 12 and the 20th anniversary of defense-waste processing at the Savannah River Site.
Monica Regalbuto, assistant secretary of the Department of Energy for environmental management, and senior federal officials will join the leadership of the contractors operating the Defense Waste Processing Facility for a pair of ceremonies.
At 9:15 a.m., officials will place a marker noting the operational closure of Tank 12, one of the tanks holding liquid radioactive waste left over from the processing of material for nuclear bombs. This is the eighth tank formally closed in the 20 years since the site’s cleanup has been in operation.
The second ceremony at 12:30 p.m. is the placement in the Glass Waste Storage Building of the 4,000th canister of glassified waste at the site. It represents approximately the halfway point in the glassification of the liquid waste.
Turning the waste into glass neutralizes its radioactivity to make it safer to store.
