Assessment of Mission Support and Test Services, LLC Issues Management at the Nevada National Security Site

The U.S. Department of Energy (DOE) Office of Environment, Safety, and Health Assessments, within the independent Office of Enterprise Assessments (EA), assessed the effectiveness of Mission Support and Test Services, LLC (MSTS) in identifying and correcting issues impacting safety to prevent recurrence and assessed National Nuclear Security Administration (NNSA) Nevada Field Office (NFO) oversight of MSTS’s management of these issues. This assessment was conducted remotely due to the pandemic from the coronavirus disease of 2019 (COVID-19), with the majority of interviews occurring July 13 – 23, 2020, and August 31 – September 10, 2020. In fiscal year (FY) 2019, EA identified issues management as a targeted review area. This assessment is the fourth review examining corrective action processes. Results from these targeted reviews and from other EA assessments will be documented in a lessons-learned report that will contain EA’s overall assessment on issues management across the DOE complex.
