Title: Mitigation of Beyond Design Basis Events (MBDBE) [NRC-2014-0240]  
Abstract:

This rule would enhance mitigation strategies for nuclear power reactors for beyond-design-basis external events.  This rulemaking addresses recommendations from the Near-Term Task Force (NTTF) related to station blackout, spent fuel pool long-term cooling, and emergency preparedness (NTTF Recommendations 4, 7, 8, and portions of 9, 10, and 11).  In staff requirements memorandum (SRM)-SECY-11-0124, the Commission directed the staff to initiate the station blackout rulemaking as a high-priority activity.  The staff’s proposal is intended to produce a more seamless accident response capability that includes emergency operating procedures, the newly imposed strategies and guidelines for beyond-design-basis external events, and the extensive damage mitigation guidelines.  In SRM-SECY-14-0046, the Commission approved the consolidation of the rulemaking activities.  The rulemaking would make generically applicable the requirements in the Mitigation Strategies Order EA-12-049 and Spent Fuel Pool Instrumentation Order EA-12-051 from 2012.  This rulemaking would partially address Petition for Rulemaking (PRM)-50-96 for long-term cooling capabilities in the event of a solar storm.   Additionally, this rule fully addresses PRMs 50-97, 50-98, 50-100, 50-101, and 50-102.
