fication 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.126 IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and histhat the review 127 supports the following kinds of statements and conclusions which should be included in the staff's safety evaluation report. (For completeness, this evaluation finding includes the RSB SRXB review effort described in SRP Section 15.6.5.) 128 The emergency core cooling system (ECCS) includes the piping, valves, pumps, heat exchangers, instrumentation, and controls used to transfer heat from the core following a loss-of-coolant accident. The scope of review of the ECCS for the __________ plant included piping and instrumentation diagrams, equipment layout drawings, failure modes and effects analyses, and design specifications for essential components. The review has included the applicant's proposed design criteria and design bases for the ECCS and the manner in which the design conforms to these criteria and bases. The staff concludes that the design of the Emergency Core Cooling System is acceptable and meets the requirements of General Design Criteria 2, 4, 5, 17, 27, 35, 36, and 37; 10 CFR 50.34(f)(1)(vii) , (viii) , (x) , and (xi) ; 10 CFR 50.34(f)(2)(xxvi) and 10 129 130 131 132 133 CFR 50.46 This conclusion is based on the following: 134 (1) The applicant has met the requirements of GDC 2 with regard to the seismic design of nonsafety systems or portions thereof
