mponents on system drawings, and checks that the SAR information contains verification that minimum system flow and heat transfer requirements are met for each accident situation for the required time spans. For each case, the design will be acceptable if minimum system requirements are met. 7. The SAR is reviewed to assure ensure that the applicant has committed to address the potential for water hammer in the auxiliary cooling water systems and willhas provided67 means for prevention, or avoidance, such as venting and filling capability and operating procedures for avoidance of water hammer. Guidance for water hammer prevention and mitigation is found in NUREG-0927 (Reference 12).68 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.69 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his that the review 70 supports conclusions of the following type to be included in the staff's safety evaluation report (SER):71 The reactor auxiliary cooling water systems include pumps, heat exchangers, valves and piping, expansion tanks, makeup piping, and the points of connection or interfaces with other systems. Portions of the reactor auxiliary cooling water systems that are necessary for safe shutdown, accident prevention or accident mitigation are designed to seismic Category I and Quality Group C requirements. Based on the review of the applicant's proposed design criteria,
