Field Office: Located south of Aiken, South Carolina, the Savannah River Field Office (SRFO) is responsible for the NNSA Defense Program missions at the Department of Energy's Savannah River Site (SRS). The primary missions are reclamation of previously used tritium reservoirs; receipt, packaging and shipping of reservoirs; recycling, extraction, and enrichment of tritium gas in support of the maintenance of the nuclear weapons stockpile, including the U.S. stockpile of tritium; Limited-Life Component Exchange Reservoir Surveillance and Tritium Extraction in support of the maintenance of the nuclear weapons stockpile. The SRS is also the location where three interrelated facilities will be built and operated to implement the United States' nonproliferation commitment to dispose of its surplus weapon-grade plutonium. These facilities are the Mixed Oxide (MOX) Fuel Fabrication Facility (under construction), the Pit Disassembly and Conversion Facility (PDCF), and the Waste Solidification Building (WSB).
Site: The Savannah River Site (SRS) is owned by the U.S. Department of Energy, but the NNSA operates Tritium facilities on the site to supply and process tritium, a radioactive form of hydrogen gas that is a vital component of nuclear weapons. The NNSA-SRS loads tritium and non-tritium reservoirs; including reclamation of previously used tritium reservoirs, receipt, packing and shipping of reservoirs; recycling, extraction, and enrichment of tritium gas and laboratory operations. Today, the Tritium Extraction Facility (TEF) at SRS is the only source of new tritium for the U.S. nuclear weapons stockpile. TEF safely and efficiently extracts tritium gas from rods irradiated in a commercial reactor. Also at SRS is the NNSA Office of Site Engineering and Construction Management, which manages the activities related to U.S. nonproliferation efforts to dispose of surplus highly enriched uranium under the NNSA Uranium Enrichment project and dispose of surplus weapons-grade plutonium through the Mixed Oxide (MOX) Fuel Fabrication Facility, the Pit Disassembly and Conversion Facility (PDCF), and the Waste Solidification Building in F Area. SRS is currently managed and operated by Savannah River Nuclear Solutions, LLC.
