�withstanding” and/or “coping” during the event should be capable of functioning under the expected environmental conditions associated with the event. The station blackout analysis is therefore verified to appropriately address the potential failures of equipment/systems during the event (e.g., loss of or degraded 9.4.5-9 DRAFT Rev. 3 - April 1996 operability of the ESFVS, as appropriate), the expected environmental conditions associated with the event, the operability and reliability of equipment necessary to cope with the event under the expected environmental conditions, and the habitability of plant areas requiring operator access during the event and associated recovery period. Those portions of the ESFVS that are identified in a coping analysis as necessary to support the functioning of equipment required to cope with the event or recovery therefrom are verified to be of sufficient capacity and capability to provide such support. Meeting the requirements 10 CFR 50.63 provides assurance that necessary operator actions can be performed and that necessary equipment will be functional under the expected environmental conditions during and following a station blackout, thereby ensuring that the core will be cooled and appropriate containment integrity will be maintained.58 III. REVIEW PROCEDURES The procedures below are used during construction permit (CP) review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II. For the review of operating license (OL), standard design certification, or combined license (COL) applications, the procedures are 59 utilized to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. The primary reviewer will coordinate this review with the other branches' areas of review as stated in subsection I. The
