generating station which would require protective action. 10. To verify that the relevant requirements of 10 CFR 50.63 are met, if an AAC source is proposed for safe shutdown in the event of a station blackout, the capacity, capability, reliability, and independence of the AAC power source is reviewed in accordance with Appendix B (attached to this SRP section).79 For new applications, the reviewer verifies, using Appendix B of this SRP section, that the AAC for station blackout is of diverse design (with respect to onsite sources), is consistent with guidance in Regulatory Guide 1.155, has adequate capacity, and has capability for powering at least one complete set of normal safe shutdown loads.80 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.81 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that the review supports conclusions of the following type, to be included in the staff's safety evaluation report: The offsite power system includes two or more identified circuits from the grid and its transmission lines to the onsite distribution system. The review of the offsite power 82 system for the __________ plant covered single-line diagrams (CP and OL), station layout drawings (CP and OL) and schematic diagrams (OL) , and descriptive 83 information. The basis for acceptance of the offsite power system in our review was conformance of the design criteria and
