• Sommario/riassunto: The Energy Policy Act of 1992 called on the National Academy of Sciences to conduct a study and provide recommendations for reducing the costs of decontaminating and decommissioning (D&D) the nation's uranium enrichment facilities located at Oak Ridge, Tennessee; Raducah, Kentucky; and Portsmouth, Ohio. This volume examines the existing plans and cost estimates for the D&D of these facilities, including such elements as technologies, planning and management, and identifies approaches that could reduce D&D costs. It also assesses options for disposition of the large quantities of depleted uranium hexafluoride that are stored at these sites.
