pment necessary to provide core cooling and decay heat removal or maintain containment integrity following a station blackout. Regulatory Guide 1.155 describes a method acceptable to the NRC staff for complying with 10 CFR 50.63. Regulatory Guide 1.155, Position 3.2.2, indicates that the capability of all systems and components necessary to provide core cooling and decay heat removal following a station blackout should be determined, including compressed air capacity, when determining the plant's capability to cope with a station blackout. Position 3.3.3 of the Regulatory Guide provides guidance regarding the use of alternate compressed air sources if the compressed air capacity is not sufficient to cope with a station blackout. Position 3.5 of the Regulatory Guide provides guidance for the quality assurance (QA) activities and specifications for non-safety-related equipment used to meet the requirements of 10 CFR 50.63 and not already covered by existing QA requirements of 10 CFR 50, Appendix B. Compliance with 10 CFR 50.63 and the DRAFT Rev. 2 - April 1996 9.3.1-8 positions of Regulatory Guide 1.155 regarding the ability to withstand or cope with, and recover from a station blackout provides additional defense-in-depth against unacceptable offsite consequences should both offsite and onsite emergency ac power systems fail concurrently.65 III. REVIEW PROCEDURES The procedures below are used during the 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 recommendations and requirements given in subsection II of this SRP section. For operating license (OL) reviews, the procedures are used 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 procedures for OL and DC reviews include a determination 66 that the content and intent of the
