items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. The onsite power system includes the standby power sources, distribution systems, auxiliary supporting systems, and instrumentation and controls required to supply power to safety-related components and systems. The review of the ac power system for the __________ plant covered the descriptive information, functional logic diagrams, electrical single-line diagrams, preliminary and final physical arrangement drawings, and electrical control and schematics. The basis for acceptance of the ac power system in this review was conformance of the design criteria and bases to the Commission's regulations as set forth in the GDCs of Appendix A to 10 CFR Part 50. The staff concludes that the plant design is acceptable and meets the requirements of GDCs 2, 4, 5, 17, 18, and 50. This conclusion is based on the following: 1. The applicant has met the requirements of GDC 2, "Design Basis for Protection Against Natural Phenomena," with respect to SSCs of the ac power systems being capable of withstanding the effects of natural phenomena such as earthquakes, tornadoes,
