Independent Assessment of Occupational Injury and Illness Recordkeeping and Reporting at the Y-12 National Security Complex Uranium Processing Facility

The U.S. Department of Energy Office of Enterprise Assessments (EA) conducted an independent assessment of occupational injury and illness (OII) recordkeeping and reporting at the Y-12 National Security Complex (Y-12) Uranium Processing Facility (UPF) from September to November 2024 at the request of the National Nuclear Security Administration’s Y-12 Acquisition and Project Management Office (APMO). This assessment evaluated the OII recordkeeping program and accuracy of case records from calendar year 2022 through the third quarter of 2024. Consolidated Nuclear Security, LLC (CNS) is the management and operating contractor for Y-12 and has subcontracted Bechtel National, Inc. (BNI) to construct the UPF. The OII recordkeeping and reporting program at the UPF is implemented by BNI and lower-tier subcontractors. This assessment also evaluated the oversight related to OII recordkeeping and reporting provided by APMO.
