The Savannah River Site is a key U.S. Department of Energy industrial complex responsible for environmental stewardship, environmental cleanup, nuclear waste management and disposition of nuclear materials.
The National Nuclear Security Administration Savannah River Field Office and the Savannah River National Laboratory are located at SRS. Additionally, the University of Georgia Savannah River Ecology Laboratory and the USDA Forest Service Savannah River along with several major contractors are also located at the 310-square-mile-site in Aiken, South Carolina.

Fact Sheets
During the 1950s, SRS began to produce materials used in nuclear weapons, primarily tritium and plutonium-239. Five reactors and support facilities were built to produce these nuclear materials. Irradiated materials were moved from the reactors to one of the two chemical separations plants. In these facilities, known as “canyons,” the irradiated fuel and target assemblies were chemically processed to separate useful products from waste. After refinement, nuclear materials were shipped to other DOE sites for final application. SRS produced about 36 metric tons of plutonium from 1953 to 1988.
