cable, and recovering from, a station blackout in accordance with 10 CFR 50.63 and Regulatory Guide 1.155, Positions C.3.2.2, C.3.3.2, and C.3.3.4.65 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.66 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: 10.4.9-13 DRAFT Rev. 3 - April 1996 The auxiliary feedwater system includes all components and equipment from the condensate storage tank (normal operation) or the seismic Category I emergency water supply (including valves and cross connections) to the connection with the steam generators. The AFWS is designed to seismic Category I requirements since system operation is necessary to mitigate the consequences of an accident. This includes an automatic seismic Category I, tornado protected supply of water to the AFW pump suction. Based on the review of the applicant's proposed design criteria, design bases and safety classification for the auxiliary feedwater system, and system performance requirements during normal, abnormal, and accident conditions, the staff concludes that the design of the auxiliary feedwater system and supporting systems is acceptable and meets the Commission's regulations as set forth in 10 CFR 50.63 and General Design 67 Criteria 2, 4, 5, 19, 34, 44, 45, and 46. This conclusion is based
