In Session I of this public meeting and hearing, the Board will receive testimony from the National Nuclear Security Administration (NNSA) and its contractor concerning the safety-related risks associated with continued operation of aging defense nuclear facilities at the Y–12 National Security Complex. The Board will examine near-term and long-term risk assessment and mitigation efforts, including NNSA’s progress since the Board’s October 2, 2012, public meeting and hearing concerning improving the integration of safety into the design of the Uranium Capabilities Replacement Project, formerly known as the Uranium Processing Facility Project. In Session II, the Board will discuss Y–12’s emergency planning, response, and oversight capabilities for severe events, including the condition and survivability of emergency response facilities. The Board will also discuss the safety of nuclear operations, specifically focused on key safety initiatives to improve conduct of operations and work planning, as well as the importance of robust oversight to sustain long-term improvements.
