Independent Assessment of Shutdown and Inactive Facility Risk Management at the Hanford Site

The U.S. Department of Energy (DOE) Office of Enterprise Assessments (EA) conducted an independent assessment of the effectiveness of risk management by the Central Plateau Cleanup Company (CPCCo) at shutdown and inactive facilities at the Hanford Site in December 2022. This assessment evaluated the effectiveness of CPCCo in managing the risks associated with shutdown or inactive hazard category 2 nuclear facilities, specifically the Plutonium Uranium Extraction Plant, Reduction-Oxidation Plant, B Plant, and Waste Encapsulation and Storage Facility. This assessment also evaluated the effectiveness of the DOE Richland Operations Office’s and Office of River Protection’s (together “DOE Hanford”) oversight of CPCCo’s management of these facilities.
