ion, and power sources with respect to capability, capacity, and reliability during normal and emergency conditions, including ATWS events, as part of theirits 39 primary review responsibility for SRP Sections 7.1, and 7.3 through 7.5, and 7.8 (proposed) for HICB and Section 8.3 for PSB.40 9. The ICSB and Power Systems Branch (PSB)Electrical Engineering Branch (EELB) evaluates system controls, instrumentation, and power sources with respect to capability, capacity, and reliability during normal, abnormal, and emergency conditions, and evaluates conformance with station blackout requirements, as part of theirits primary 41 review responsibility for SRP Sections 7.1 and 7.3 through 7.5 for HICB and Section 8.3 for PSBChapter 8.42 For those areas of review identified above as being reviewed as part of the primary responsibility ofreview under other branchesSRP sections, the acceptance criteria and their methods of application are contained in the referenced SRP sections corresponding to those branches. 43 II. ACCEPTANCE CRITERIA Acceptability of the design of the auxiliary feedwater system, as described in the applicant's safety analysis report (SAR), is based on specific regulations, general design criteria and 44 regulatory guides. Listed below are the specific criteria used in this SRP section as they relate to the AFWS. 1. General Design Criterion 2, as related to structures housing the system and the system itself being capable of withstanding the effects of earthquakes. Acceptability is based on meeting position C.1 of Regulatory Guide 1.29 for safety-related portions and position C.2 for nonsafety-related portions. 2. General Design Criterion 4, with respect to structures housing the system and the system itself being capable of withstanding the effects of external missiles and internally generated missiles, pipe whip, and jet impingement forces associated with pipe breaks. The basis for acceptance for meeting this criterion is set forth in the SRP Section 3.5
