ions 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. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. The procedures are used during construction permit review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary SAR meet the acceptance criteria of subsection II of this SRP section. For the review of an operating license application, 9.4.5-9 Revision 3 - March 2007 the procedures are used to verify that the initial design criteria and bases are implemented appropriately in the final design as set forth in the final SAR. These procedures should be followed for the review of a DC and a COL application. The primary reviewer coordinates this review with other areas of review as stated in subsection I of this SRP section. The primary reviewer uses such inputs as required to ensure that this review procedure is complete. As a result of various ESFVS designs proposed by applicants, there will be variations in system requirements. For purposes of this SRP section, a typical system is assumed which has fully redundant subsystems, each having an identical essential (safety features) portion. 1. The SAR is reviewed to verify that the system description and piping and instrumentation diagrams (P&IDs) show the ESFVS equipment used for normal operation, and the ambient temperature limits for the areas serviced. The system
