ants are required to determine by analysis (1) an acceptable minimum time for which a plant can withstand or cope with a station blackout (station blackout duration) and (2) the plant's capability for maintaining adequate core cooling and appropriate containment integrity for the station blackout duration and subsequent recovery from the event. In addition, all licensees and applicants are required to have procedures and training for the station blackout event for the specified duration and recovery therefrom.

Safe shutdown (non-DBA) is defined for station blackout as bringing the plant to those shutdown conditions specified in plant technical specifications as Hot Standby or Hot Shutdown, as appropriate. Where the licensee/applicant so elects, the review conducted herein must establish that the information submitted and commitments made regarding the AAC source provide reasonable assurance of its conformance with the rule.
