Fluor’s nuclear experience goes back to the early days of atomic energy. Starting in 1946, Fluor designed and constructed numerous facilities to support the U.S. Atomic Energy Commission/U.S. Department of Energy. In 1970, Fluor entered the commercial nuclear business by constructing Alabama Power’s Farley Nuclear Plant. During the 1970s and 1980s, Fluor designed three nuclear power plants, constructed 10 nuclear power plants and supported construction on another 10 nuclear units. Over the past five decades Fluor has also provided operating plant support services to 90 U.S. and international nuclear units. In 1992, Fluor began performing nuclear decommissioning and environmental cleanup services at the U.S. Department of Energy’s nuclear sites.

In 1996, Fluor expanded its nuclear expertise with the award of the management and operations contract at the DOE Hanford Site. Building on this experience, the Fluor partnership was selected to manage operations, including the Savannah River National Laboratory, at DOE’s Savannah River Site. In 2015, Fluor as part of a consortium was selected to manage the operations of the Canadian Nuclear Laboratories. Recently Fluor was awarded two major design services subcontracts for the design of the balance of plant/services of the Savannah River Plutonium Processing Facility and the Tritium Finishing Facility at DOE’s Savannah River Site. Fluor has full scope experience in design, construction, operations/maintenance, decommissioning and demolition and environmental remediation for commercial nuclear power plants and government nuclear materials production facilities.
