The 233-S Plutonium Concentration Facility received plutonium nitrate paste from the nearby Reduction-Oxidation (REDOX) Facility and concentrated the plutonium for shipment to Hanford's Plutonium Finishing Plant. Operations ceased in 1967 and the Facility languished in a state of minimal maintenance until the mid-1990's when a decision was made to decontaminate and demolish (D&D) it. This work is being performed as a pilot project that integrates DOE nuclear safety analysis and worker safety requirements with Environmental Protection Agency (EPA) requirements under CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act, 1980). The pilot project is a CERCLA non-time critical removal action.
