Independent Assessment of Safety System Management for Liquid and Gaseous Waste Operations at Oak Ridge National Laboratory - May 2022

The U.S. Department of Energy Office of Enterprise Assessments (EA) conducted an independent assessment of safety system management for Liquid and Gaseous Waste Operations (LGWO) at Oak Ridge National Laboratory from November 29 to December 3, 2021. The Oak Ridge Office of Environmental Management (OREM) is responsible for management and oversight of LGWO. This assessment evaluated the effectiveness of management and operating contractor, URS|CH2M Oak Ridge, LLC (UCOR), processes and activities used to manage and maintain the performance of risk-significant structures, systems, and components (SSCs) within the LGWO complex that may impact nuclear safety, and site actions taken in response to key recommendations from the 2016 UCOR study, Liquid and Gaseous Waste Operations Engineering Evaluation and Extended Life Study, and an associated 2018 Phase 2 follow-on study. Additionally, this assessment evaluated OREM oversight of LGWO safety system management.
