Content:
ide 1.155 provides guidance for complying with station blackout requirements. Regardless of the extent, if any, to which the CRAVS is expected to function to maintain suitable environmental conditions during a station blackout event, control room-area equipment that is necessary to accomplish core cooling, maintenance of appropriate containment integrity, and other functions that constitute 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 operability of the CRAVS, 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 CRAVS, if any, 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 control room-area equipment will be functional under the expected environmental conditions during and following a station 9.4.1-9 DRAFT Rev. 3 - April 1996 blackout, thereby ensuring that the core will be cooled and appropriate containment integrity will be maintained.60 III. REVIEW PROCEDURES The procedures below are used during the construction permit (CP) or standard design certification review to determine that the design criteria and bases and the preliminary design 61 as set forth in the preliminary safety analysis reportSAR meet the acceptance
