Radiological characterization and decision analysis for the SFE-20 waste tank and vault

Westinghouse Idaho Nuclear Company, Inc. (WINCO), has completed a physical and radiological characterization of the SFE-20 Waste Tank Facility located at the Idaho Chemical Processing Plant (ICPP). The objectives of this characterization are to physically describe the SFE-20 tank and its related components, measure and record radiation fields, determine the radionuclide content of smearable contamination on and about the SFE-20 tank, and determine the radionuclide type and concentration in the tank contents and surface soil above the tank. A decision analysis was performed to select the best method and time frame for decommissioning the SFE-20 Tank, Vault and Pump Pit. 2 references, 14 figures, 9 tables.
