y of these components on system drawings, 10.3-13 DRAFT Rev. 4 - April 1996 and checks that the SAR contains verification that minimum requirements are met for each accident situation for the required time spans. For each case the design is acceptable if minimum system requirements are met. 8. The SAR is reviewed to assure that the applicant has committed to address the potential for water (steam) hammer and relief valve discharge loads, and will take adequate 69 procedures action to minimize such occurrences. Drain pots, line slope and valve operators should be addressed. 9. The reviewer confirms that the MSSS system capability is sufficient with respect to the plant's ability to cope with, and recover from an SBO of a specified duration by determining compliance with Regulatory Guide 1.155 positions C.3.2, C.3.3, and C.3.5 as related to the design of the MSSS system. This review is coordinated with the review of the SBO event under SRP Section 8.4 (proposed).70 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.71 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his the review supports 72 conclusions of the following type, to be included in the staff's safety evaluation report: The main steam supply system (MSSS) includes all components and piping from the outermost containment isolation valves (for BWRs) [from the steam generator connection (for PWRs)] up to and
