grid, including transmission lines, breakers, and transformers used for supplying preferred power from distant sources, are reviewed to ensure that each path has sufficient capacity and capability to perform its intended function. This will require examination of loads required to be powered for each plant operating condition; continuous and fault ratings of breakers, transformers, and transmission lines; and loading, unloading, and transfer effects on equipment; and power capacity available from each source. 4. The instrumentation required for monitoring and indicating the status of the preferred power system is reviewed to ensure that any change in the preferred power system that would prevent it from performing its intended function will be immediately identified by the control room operator. Also, all instrumentation for initiating safety actions associated with the preferred power system is reviewed. 5. The capability to test the preferred power system is reviewed. 8.2-3 Revision 4 - March 2007 6. Environmental conditions such as those resulting from high and low atmospheric temperatures, high wind, rain, lightning discharges, snow, and ice are considered in the review of the preferred power system to determine any effects on function. 7. Quality group classifications of equipment of the preferred power system are reviewed. 8. The interface(s) of the preferred power system with the AAC power source, if provided, is reviewed. The design, operation, and performance of the AAC power source are reviewed in accordance with SRP Section 8.4. 9. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed
