Savannah River Site
The Savannah River Site (SRS) is a nuclear reservation in the United States in the state of South Carolina, located on land in Aiken, Allendale and Barnwell Counties adjacent to the Savannah River, 25 miles (40 km) southeast of Augusta, Georgia. The site was built during the 1950s to refine nuclear materials for deployment in nuclear weapons. It covers 310 square miles (800 km2) and employs more than 10,000 people. The site is protected by G4S Secure Solutions.
It is owned by the U.S. Department of Energy (DOE). The management and operating contract is held by Savannah River Nuclear Solutions LLC (SRNS), and the Liquid Waste Operations contract is held by Savannah River Remediation, which is a team of companies led by URS Corp. A major focus is cleanup activities related to work done in the past for American nuclear buildup. Currently none of the reactors on-site are operating (see list of nuclear reactors), although two of the reactor buildings are being used to consolidate and store nuclear materials. SRS is also home to the Savannah River National Laboratory and the USA's only operating radiochemical separations facility. Its tritium facilities are also the United States' only source of tritium, an essential component in nuclear weapons. The USA's only mixed oxide fuel (MOX) manufacturing plant is being constructed at SRS overseen by the National Nuclear Security Administration. When operational, the MOX facility will convert legacy weapons-grade plutonium into fuel suitable for commercial power reactors.
Future plans for the site cover a wide range of options, including host to research reactors, a reactor park for power generation, and other possible uses. DOE and its corporate partners are watched by a combination of local, regional and national regulatory agencies and citizen groups. Security is provided by Centerra Security Services, Inc.
In 1950, the federal government requested DuPont to build and operate a nuclear facility near the Savannah River in South Carolina. The company had expertise in nuclear operations, having designed and built the plutonium production complex at the Hanford site for the Manhattan Project during World War II. A large portion of farmland, the towns of Ellenton and Dunbarton, and several other communities including Meyers Mill, Leigh, Robbins, and Hawthorne were bought under eminent domain, and the site of 310 square miles (800 km2) became the Savannah River Site, managed by the U.S. Atomic Energy Commission. Biologists from the University of Georgia, led by professor Eugene Odom, began ecological studies of local plants and animals in 1951, and plant construction began.
Production of heavy water for site reactors started in the Heavy Water Rework Facility in 1952, and the first production reactor, R Reactor, went critical in 1953. P, L, and K Reactors followed in 1954, and the first irradiated fuel was discharged. F Canyon, the world's first operational full-scale PUREX separation plant, began radioactive operations on 4 November. PUREX (Plutonium and Uranium EXtraction) extracted plutonium and uranium products from materials irradiated in the reactors.
In 1955, C Reactor went critical. The first plutonium shipment left the site. H Canyon, a chemical separation facility, began radioactive operations. Permanent tritium facilities became operational and the first shipment of tritium to the Atomic Energy Commission (AEC) was made. In 1956, construction of the basic plant was complete.
The neutrino was discovered by Fred Reines and Clyde Cowan using the flux from P Reactor, with confirmation published in the 20 July 1956 issue of Science. Reines was awarded the 1995 Physics Nobel Prize; Cowan had already died.
In 1961, the AEC established a permanent ecology laboratory on the site; two Army barracks were converted into laboratory space for the scientists. The next year, the University of Georgia hired a full-time staff with doctoral degrees to expand the research effort. Known initially as the Laboratory of Radiation Ecology, it was renamed in the mid-1960s the Savannah River Ecology Laboratory, reflecting the broad spectrum of ecological studies carried out on the site.
In 1962, the Heavy Water Components Test Reactor (HWCTR) went into operation, testing the heavy water system for use with civilian power reactors. In 1963, Receiving Basin for Off-Site Fuels (RBOF) received its first shipment of off-site spent nuclear fuel. That same year, Curium-244 was produced as a heat source for space exploration. This was the first full scale conversion of an SRP reactor load to nonweapons materials.
R-Reactor and HWCTR were shut down in 1964. In 1965, Californium-252, the heaviest isotope produced at SRP, was separated as a byproduct of the Curium program. Beginning in 1969, Californium-252 was made in a separate production program.
Following the 1966 Palomares B-52 crash, the Savannah River Site received contaminated soil from the environmental clean up and remediation. Soil with radiation contamination levels above 1.2 MBq/m2 was placed in 250-litre (66 U.S. gallon) drums and shipped to the Savannah River Plant for burial. A total of 2.2 hectares (5.4 acres) was decontaminated by this technique, producing 6,000 barrels. 17 hectares (42 acres) of land with lower levels of contamination was mixed to a depth of 30 centimetres (12 in) by harrowing and plowing. On rocky slopes with contamination above 120 kBq/m2, the soil was removed with hand tools and shipped to the United States in barrels.
In 1968, L Reactor was shut down for upgrades, and, in 1971, K Reactor became the first reactor to be controlled by computer.
The site was designated as a National Environmental Research Park in 1972.
1977 saw the startup of the Plutonium Fuel Fabrication (PUFF) Facility.
The Savannah River Archaeological Program (SRARP) was established onsite in 1978 to perform data analysis of prehistoric and historic sites on SRP land.
In 1981, an environmental cleanup program began. M Area Settling Basin cleanup began under the Resource Conservation and Recovery Act (RCRA). The heavy water rework facility was closed in 1982. Construction of the Defense Waste Processing Facility (DWPF) began in 1983. Wackenhut Services Incorporated (WSI) began providing security support services at SRP.
In 1985, HB-Line began producing plutonium-238 for NASA's deep-space exploration program. The L-Reactor was restarted and C-Reactor shut down. A full-scale groundwater remediation system constructed in M-Area.
Construction of Saltstone and of the Replacement Tritium Facility began in 1986. In 1987, DuPont notified DOE that it would not continue to operate and manage the site. The Effluent Treatment Project (ETP) construction began.
In 1988, K, L and P Reactors were shut down. An Effluent Treatment Facility began operations to treat low-level radioactive wastewater from the F and H Area Separations facilities. In 1989, the site was included on the National Priority List and became regulated by the EPA. Westinghouse Savannah River Company (WSRC) assumed management and operation of site facilities. The name of the facility changed from Savannah River Plant (SRP) to Savannah River Site (SRS).
In 1990, construction of a cooling tower for K Reactor began. Saltstone started operation. In 1991, the mixed waste management facility became the first site facility to be closed and certified under the provisions of RCRA. L Reactor and M Area settling basin were shut down. With the end of the Cold War, production of nuclear materials for weapons use ceased.
Roger D. Wensil, a pipe-fitter, worked for the B.F. Shaw Co., a subcontractor at Savannah River. In 1985, Wensil was dismissed as a whistleblower, after he complained of safety violations and illegal drug use among construction workers building a sensitive nuclear waste-handling facility at the plant. In 1992, the U.S. Congress enacted "nuclear weapons whistleblower protection".
In 1992, the cooling tower was connected to the K Reactor, and the reactor operated briefly for the last time. The Secretary of Energy announced the phase-out of all uranium processing. Non-radioactive operations began at the Replacement Tritium Facility and the Defense Waste Processing Facility (DWPF). K Reactor was placed in cold standby condition in 1993. Non-radioactive test runs of the Defense Waste Processing Facility began. Construction began on the Consolidated Incineration Facility. Tritium introduced into the Replacement Tritium Facility and radioactive operations began. The Workforce Transition and Community Assistance was started.
In 1994, the Savannah River Site Citizens Advisory Board was established. The Replacement Tritium Facility saw its startup. In 1996, DWPF introduced radioactive material into the vitrification process. K Reactor was shut down. F Canyon was restarted and began stabilizing nuclear materials. In 1997, the first high-level radioactive waste tanks were closed, numbers 17 and 20. The Cold War Historic Preservation Program was begun.
In 2000, the K-Reactor building was converted to the K Area Materials Storage Facility. The Savannah River Site was selected as the location of three new plutonium facilities for: a MOX fuel fabrication; pit disassembly and conversion; and plutonium immobilization. WSRC earned the DOE's top safety performance honor of Star Status.
The first shipment of transuranic waste was sent to the DOE's Waste Isolation Pilot Plant (WIPP) Project in New Mexico in 2001. DWPF completed production of four million pounds of environmentally acceptable classified waste.
In 2002, the F Canyon and FB Line facilities completed their last production run. The Savannah River Technology Center participated in a study of using a nuclear power reactor to produce hydrogen from water. Scientists reported finding a new species of radiation-resistant extremophiles inside one of the tanks. It was named kineococcus radiotolerans.
In January 2003, Westinghouse Savannah River Co. completed transferring the last of F Canyon’s radioactive material to H Tank Farm. DWPF began radioactive operations with its second melter, installed during a shutdown. The last depleted uranium metal was shipped from M Area for disposition at Envirocare of Utah. The last unit of spent nuclear fuel from RBOF was shipped across the site to L Reactor in preparation for RBOF's deactivation. Salt Waste Processing Facility (SWPF) construction began.
In 2004, the site shipped its 10,000th drum of transuranic waste to the Waste Isolation Pilot Plant (WIPP), a DOE facility in New Mexico, 12 years ahead of schedule. In a visit, Secretary of Energy Spencer Abraham designated the Savannah River National Laboratory (SRNL), one of 12 DOE national laboratories. Two prototype bomb disposal robots developed by SRNL were deployed for military use in Iraq.
2005 saw the Tritium Extraction Facility (TEF) completed for the purpose of extracting tritium from materials irradiated in the Tennessee Valley Authority's commercial nuclear reactors. Savannah River Site's first shipment of neptunium oxide arrived at the Argonne West Laboratory in Idaho. This was the last of the USA's neptunium inventory, and the last of the materials to be stabilized to satisfy commitments for stabilizing nuclear materials. F Canyon was the first major nuclear facility at the site to be suspended and deactivated. Low-enriched uranium (LEU) from the site was used by a Tennessee Valley Authority nuclear power reactor to generate electricity. The tritium facilities modernization and consolidation project completed start-up and replaced the gas purification and processing that took place in 232-H. WSRC began multi-stage layoffs of permanent employees.
In 2006, design work took place for the Salt Waste Processing Facility (SWPF), a facility designed to process radioactive liquid waste stored in underground storage tanks at the site. The SWPF project work is performed by a group anchored by Parsons Corp. Work continued on design of the MOX fuel fabrication facility by a company now known as Shaw AREVA MOX Services. The SRNL was designated as the Department of Energy Office of Environmental Management’s "Corporate Laboratory." Aiken County’s new Center for Hydrogen Research opened its doors. F-Area deactivation work was completed as was T-Area closure.
In 2007, the Tritium Extraction Facility (TEF) opened. On 1 August, construction officially began on the $4.86 billion MOX facility. Following startup testing, the facility expects a disposition rate of up to 3.5 tons of plutonium oxide each year.
In 2008, Savannah River Nuclear Solutions (SRNS) was awarded the contract for Maintenance and Operation of SRS. Savannah River Remediation (SRR) was awarded the contract for the Liquid Waste Operations of SRS. Historical markers were placed in P and R Areas commemorating the role both reactors played towards winning the Cold War. Construction on the Waste Solidification Building (WSB) began.
In 2009, SRS began The American Reinvestment and Recovery Act (ARRA) project representing a $1.6 billion investment in SRS. This project, expected to run through fiscal year 2011, will result in the accelerated cleanup of nuclear waste at SRS and a significant reduction in the site footprint. In 2009 alone, more than 1,500 new workers were hired and over 800 jobs retained, due to ARRA funding. SRS construction employees reached 23 million hours (11 consecutive years) without a lost time injury case.
M Area closure was completed in 2010, with the P and R Areas following in 2011.
For 2015, Congress has funded the MOX project with $345 million for FY 2015. The project is expected to continue receiving funding in the coming years. The facility will require an estimated $500 million per year to optimize construction progress.
On 17 August 2015, the Savannah River Site was put under lockdown due to a "security event". 
Savannah River is home to the following nuclear reactors:
|Reactor name||Start-up date||Shutdown date|
|R Reactor||December 1953||June 1964|
|P Reactor||February 1954||August 1988|
|K Reactor||October 1954||July 1992|
|L Reactor||July 1954||June 1988|
|C Reactor||March 1955||June 1985|
Management of the Savannah River Site was to be bid in 2006, but the Department of Energy extended the contract with the existing partners for 18 months to June 2008.
In 2006 DOE decided to split the WSRC contract into two new separate contracts, i.e. the M&O Contract and the Liquid Waste Contract to be awarded before June 2008. Responding to the DOE RFP, the Savannah River Nuclear Solutions (SRNS), LLC - now a Fluor partnership with Honeywell, and Huntington Ingalls Industries (formerly part of Northrop Grumman) - submitted a proposal in June 2007 for the new M&O Contract. A team led by URS and including many of the WSRC partners also submitted a proposal. On January 9, 2008 it was announced that SRNS LLC had won the new contract, with a 90-day transition period to start 24 January 2008. However, the transition was delayed by a protest filed with GAO by the URS team on 22 January 2008. The GAO denied the protest on 25 April. DOE-SR then directed SRNS to start transition on 2 May and take over operation on 1 August 2008.
