Content:
irements on the plant regarding the capability to ensure that the core is cooled in the event of a station blackout for a determined duration. The MSSS may supply pumps (e.g., AFW or RCIC) and provide decay heat removal capability necessary for core cooling and/or safe shutdown (non-design basis accident), respectively, during a station blackout. Its design capability to operate regardless of a-c power source availability enables performance of these important functions during a station blackout. Regulatory Guide 1.155 identifies methods acceptable for complying with the requirements of 10 CFR 50.63. Meeting the requirements of 10 CFR 50.63 and the positions of Regulatory Guide 1.155 provides assurance that the MSSS system is capable of supporting core cooling and/or safe shutdown (non-design basis accident) in the event of a station blackout. 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 acceptance criteria given in subsection II of this SRP section. For review of operating license (OL) applications, the procedures are used to verify that the initial design 10.3-9 DRAFT Rev. 4 - April 1996 criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. The procedures for OL applications include a determination that the content and intent of the technical specifications prepared by the applicant are in agreement with the requirements for system testing, minimum performance, and surveillance, developed as a result of the TSBSSPB50 review, as indicated in subsection I of this SRP section. The primary reviewers, will coordinate this review with the other branches' areas of review as 51 stated in subsection I of this SRP section. The primary reviewers obtain and use such input as required to assure that this review procedure
