Safety Basis Assessment at the Hanford Site Tank Farms Tank Side Cesium Removal Facility

The U.S. Department of Energy (DOE) Office of Nuclear Engineering and Safety Basis Assessments, within the independent Office of Enterprise Assessments (EA), conducted an assessment of the safety basis amendment and safety evaluation report (SER) for incorporating the Tank Side Cesium Removal (TSCR) Facility into tank farm operations at the Hanford Site. The safety basis includes HNF-SD-WM-TSR-006, Tank Farms Technical Safety Requirements, and RPP-13033, Tank Farms Documented Safety Analysis, which have been amended to integrate the control changes required for TSCR operations. This assessment, conducted from August 2020 through February 2021, is a follow-on activity to the EA assessment of the TSCR safety design basis documents completed in early 2020, as documented in Preliminary Documented Safety Analysis Assessment at the Hanford Site Tank Farms Tank Side Cesium Removal Project, April 2020.
