Independent Assessment of Emergency Management at the Y-12 National Security Complex - April 2022

The U.S. Department of Energy (DOE) Office of Enterprise Assessments (EA) conducted an independent assessment of the emergency management program at the Y-12 National Security Complex (Y-12) during Y-12’s annual site-level exercise, Emergency Management Exercise 2021-3 (EME21-3). The assessment evaluated the effectiveness of Consolidated Nuclear Security, LLC (CNS) and the National Nuclear Security Administration Production Office (NPO) in managing and maintaining emergency response organization (ERO) performance during the site-level exercise, as required by DOE Order 151.1D, Comprehensive Emergency Management System. Additionally, EA appraised the performance of the ERO at key decision-making venues to determine whether CNS responded effectively to an operational emergency and whether appropriate response measures were taken to protect workers, responders, and the public.
