Content:
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 General Design Criteria of Appendix A to 10 CFR Part 50. The staff concludes that the plant 8.2-24 Revision 4 - March 2007 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 alternate ac (AAC) power source provided for station blackout. 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 structures, systems, and components 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 phenomana by adequate plant design. 2. The applicant has met the requirements of GDC 4, "Environmental and Dynamic Effects Design Bases," with respect to structures, systems, and components of the offsite power system being capable of withstanding dynamic effects, including effects of missiles, pipe whipping, and discharging fliuds 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, "Sharing of Structures, Systems, and Components," with respect to sharing of circuits of the preferred power system between units. Each circuit has sufficient capacity to operate the engineered safety features for a design basis accident on one unit and those systems required for concurrent safe shutdown on the remaining units. 4. The applicant has met the
