The Savannah River National Laboratory (SRNL) is a multi-program national laboratory for the U.S. Department of Energy’s (DOE) Office of Environmental Management. SRNL is located at the Savannah River Site (SRS) near Jackson, South Carolina. It was founded in 1951, as the Savannah River Laboratory as a research, development and manufacturing center for tritium production from lithium. The intended end use of the tritium was in nuclear fusion weapons, as well as in thermonuclear fusion reactors for civilian use. Plutonium production and research was a second main activity in the lab at that time.
