In August 1952, the Atomic Energy Commission, a predecessor agency to DOE, selected a tract of land in the Ohio Valley along the Scioto River in Pike County, Ohio, for the site of the Portsmouth Gaseous Diffusion Plant (GDP), the third of three GDPs in the United States. In 1956, the plant began enriching uranium for nuclear weapons. In the 1960s, Portsmouth’s mission changed to focus on producing fuel for commercial nuclear power plants and other national security applications. An extensive environmental cleanup program began at the 3,777-acre site in 1989, with deactivation and decommissioning activities initiated in 2011.
