"Savannah River Site will permanently seal in place more Cold War-era storage tanks after removing highly radioactive liquid nuclear waste.

U.S. Energy Secretary Ernest Moniz gave the South Carolina site approval to close underground storage tanks in the H-area “tank farm.”

The order is part of cleanup efforts at the site which produced materials for nuclear weapons during the Cold War."
