The U.S. Department of Energy (DOE) Office of Enterprise Assessments (EA) conducted an independent assessment of the effectiveness of nuclear criticality safety (NCS) program (NCSP) performance at the Pacific Northwest National Laboratory (PNNL), which is managed and operated for the DOE Pacific Northwest Site Office (PNSO) by Battelle Memorial Institute (BMI). The assessment also evaluated the effectiveness of PNSO oversight of BMI’s NCSP. The assessment was performed in February and March 2025.
