following type to be included in the staff's safety evaluation report (SER). The reviewer also states the bases for those conclusions. 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 system for the __________ plant covered single-line diagrams, station layout drawings and schematic diagrams, and descriptive information. 8.2-25 Revision 5 - May 2010 The basis for acceptance of the offsite power system in our review was conformance of the design criteria and bases to the Commission's regulations as set forth in the GDC 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, and 18 and also meets the requirements of 10 CFR 50.63 with regard to the AAC power source provided for SBO. 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 offsite power systems being capable of withstanding the effects of natural phenomena such as high and low atmospheric temperatures, high wind, rain, lightning discharges, ice and snow conditions, and weather events causing regional effects by locating the offsite power system and components in areas which provide protection from the effects of natural phenomena by adequate plant design. 2. The applicant has met the requirements of GDC 4, "Environmental and Dynamic Effects Design Bases," with respect to SSCs of the offsite power system being capable of withstanding dynamic effects, including effects of missiles, pipe whipping, and discharging fluids that may result from equipment failures and from events and conditions outside the nuclear power unit associated with normal operation, maintenance, testing, and postulated accidents by adequate plant design. 3. The applicant has met the requirements of GDC 5,
