Independent Assessment of Nuclear Criticality Safety Program and Controls at the Savannah River Site L-Area Facility

The U.S. Department of Energy (DOE) Office of Enterprise Assessments (EA) conducted an independent assessment of the nuclear criticality safety (NCS) program (CSP) and controls at the Savannah River Site L-Area Facility (LAF) in November and December 2024. The LAF is managed by the site management and operating contractor, Savannah River Nuclear Solutions, LLC (SRNS), which is overseen by the DOE Savannah River Operations Office (DOE-SR). DOE-SR provides oversight of environmental management programs at the Savannah River Site. The primary objective of the assessment was to evaluate the effectiveness of SRNS’s activities to manage and maintain an appropriate CSP, controls, and operating practices at the LAF. Additionally, the Federal oversight provided by DOE-SR relating to NCS was evaluated.
