Independent Assessment of Fire Protection Program Inspection, Testing, Maintenance at the Hanford Site Solid Waste Operations Complex - July 2025

The U.S. Department of Energy (DOE) Office of Enterprise Assessments (EA) conducted an independent assessment of fire protection program inspection, testing, and maintenance (ITM) at the Hanford Site Solid Waste Operations Complex (SWOC), which is managed and operated by Central Plateau Cleanup Company (CPCCo) for the DOE Hanford Field Office. This assessment evaluated the effectiveness of CPCCo programs in managing and maintaining fire protection program ITM performance, including the adequacy of causal analyses and corrective actions taken in response to adverse conditions associated with safety significant (SS) fire suppression systems (FSSs) identified by CPCCo in 2021 and 2022 at the SWOC Central Waste Complex (CWC). The assessment also reviewed the status and effectiveness of CPCCo actions taken in response to a finding documented by EA in 2019 regarding the adequacy of the SWOC documented safety analysis (DSA). The assessment was conducted in May 2025.
