This rulemaking merges: 1) Station Blackout Mitigation Strategies (RIN 3150-AJ08), and 2) Strengthening and Integrating Onsite Emergency Response Capabilities (RIN 3150-AJ11).  The purpose of this rulemaking is to 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 SRM-SECY-11-0124, the Commission directed the staff to initiate the station blackout rulemaking as a high-priority activity.  Also, SRM-SECY-11-0137 approved the staff’s proposal to strengthen and integrate onsite emergency response capabilities such as emergency operating procedures (EOPs), severe accident management guidelines (SAMGs), and the extensive damage mitigation guidelines (EDMGs).  In SRM-SECY-14-0046, the Commission approved the consolidation of the rulemaking activities.  The rulemaking will 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 will partially address 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.
