urces. Electrical ties between these systems, as well as the physical arrangement of their interface equipment, must not prevent the use of any AAC power source during loss of the offsite power system and/or onsite power sources. It is also important that provisions for an AAC source will not adversely affect performance of offsite or onsite power system functions. AAC power sources located at or near the plant should conform to guidance provided in Regulatory Guide 1.155 concerning their capacity, capability, and physical independence from onsite safety-related systems and the preferred power system. Meeting the requirements of 10 CFR 50.63 provides assurance that the nuclear power plant will be able to withstand or cope with, and recover from a station blackout and will ensure that core cooling and appropriate containment integrity are maintained.57 III. REVIEW PROCEDURES The primary objective in the review of the preferred power system is to determine that this system satisfies the acceptance criteria stated in subsection II and will perform its design functions during plant normal operation, anticipated operational occurrences, and accident conditions. In the CP review, the descriptive information, including the design bases and their relation to the acceptance criteria, preliminary analyses, electrical single-line diagrams, and preliminary physical arrangement and layout drawings, are examined to determine that the final design will meet this objective if properly implemented. During the OL review, this objective is verified by examination of final electrical schematics, physical arrangement and layout drawings, and equipment ratings identified in the SAR and confirmed during a visit to the site (SRP Section 8.1 Chapter 8, Appendix 8-B). To assure ensure that acceptance criteria stated in 58 subsection II are satisfied, the review of the proposed design is performed as described below. The primary reviewer will coordinate this review with the other branch areas
