This public meeting and hearing is the first of two hearings the Board will convene to address safety culture at Department of Energy defense nuclear facilities and the Board’s Recommendation 2011–1, Safety Culture at the Waste Treatment and Immobilization Plant. The second hearing will be announced by a separate notice at a future date. In this first hearing, the Board will receive testimony from a recognized industry expert in the field of safety culture, with a focus on the tools used for assessing safety culture, the approaches for interpreting the assessment results, and how the results can be used for improving safety culture. The Board will next hear testimony from safety culture representatives from the federal government, including senior staff of the Nuclear Regulatory Commission (NRC) and the National Aeronautics and Space Administration (NASA). NRC staff will discuss the NRC’s approach to identifying safety culture concerns at licensee facilities and how the NRC expects those concerns to be evaluated and corrected. The hearing will conclude with a discussion from NASA staff concerning NASA’s Policy for Safety and Mission Success, tools the agency uses to improve safety culture, and NASA’s experience in improving and sustaining a robust safety culture.
