The K-25 Site covers roughly 5,000 acres, or 14 percent of the Oak Ridge Reservation, approximately 13 miles from the city of Oak Ridge, Tennessee. The current site configuration is the product of past missions and programs, the most significant of which was the Oak Ridge Gaseous Diffusion Plant, which operated from the end of World War II until 1985. About 725 acres, within a security fence, contain almost 400 buildings totaling approximately 14.4 million square feet. Of this, almost 90 percent (12.5 million square feet) comprises buildings are currently undergoing or are planned for decontamination and decommissioning (D&D). These buildings include the shutdown gaseous diffusion production facilities and gas centrifuge enrichment and ancillary buildings.
