Independent Assessment of Construction Quality at the Y-12 National Security Complex Uranium Processing Facility – August 2022

The U.S. Department of Energy Office of Enterprise Assessments (EA) conducted an independent assessment of construction quality at the Y-12 National Security Complex (Y-12) Uranium Processing Facility (UPF) from May 23-27, 2022. Consolidated Nuclear Security, LLC (CNS) serves as the primary contractor for the UPF project and has subcontracted Bechtel National, Inc. (BNI) to manage and subcontract UPF design and construction activities. The National Nuclear Security Administration Y-12 Acquisition and Project Management Office (APMO) has overall Federal UPF project oversight responsibilities. The primary objective of the assessment was to evaluate the effectiveness of CNS, BNI, and subcontractor Apollo Mechanical Contractors (Apollo) quality assurance (QA) processes for the design, procurement, installation, and inspection of certain UPF heating, ventilation, and air conditioning (HVAC) structures, systems, and components (SSCs) related to nuclear safety. Additionally, the assessment evaluated the effectiveness of APMO oversight of CNS, BNI, and Apollo HVAC construction quality activities.
