Decontamination and decommissioning waste characterization and cost estimates from historical records

There are more than 600 facilities at the Savannah River Site (SRS) that are contaminated with either radioactivity, hazardous chemicals, or asbestos. The more significant facilities can be separated into broad categories for decontamination and decommissioning (D&D) planning such as plutonium facilities, waste tanks, chemical separations canyons, and nuclear reactors. Uncertainties exist in the timing, extent of stabilization, and D&D required for these production facilities. Detailed analyses of the risk, costs, and engineering feasibility are needed to define production facility end states to ensure expected reduction in health and environmental risk. In the meantime, scoping projections are required to satisfy Department of Energy (DOE) requirements for 30 year plans, and to indicate where detailed analysis should be funded.
