    Stage of Clean-up: Construction Underway

    Conditions at proposal (October 15, l984): The Rocky Flats Plant covers approximately 6,550 acres (about 11 square miles) in Jefferson County, near Golden, Colorado. The facility originally covered 2,000 acres, but a 4,550-acre "buffer zone" was added in 1974. The main processing operations are confined to approximately 384 acres within the buffer zone. The plant began operations in 1952 under the direction of the Atomic Energy Commission. The current owner is the U.S. Department of Energy (USDOE). Actual operations at the plant have been performed by contractors. Dow Chemical Co. operated the plant until June 30, l975, when the current operator, Rockwell International Corp., took over. Since its establishment, the major operation at the plant has been the fabrication and assembly of components for nuclear weapons. These operations use PLUTONIUM, URANIUM+, BERYLLIUM, stainless steel, and ALUMINUM. The facility also recovers PLUTONIUM and separates and performs research on americium.  More...
