The Savannah River Plant Waste Management Program focuses on safely handling and disposing of waste from making nuclear materials for the US Department of Energy. They store high-level radioactive liquid waste in double-containment tanks and reduce its volume through evaporation. A new facility is being built to treat low-level liquid hazardous and radioactive waste. They use engineered trenches for solid low-level waste and updated procedures for transuranic waste storage. A new disposal method, Greater Confinement Disposal, is being tested for intermediate-level waste. Nonradioactive hazardous waste is stored on site.
