has been altered by additions to, or changes in, the structure, and (9) complete records. 3. GDCs 33, 34, 35, 38, 41, and 44 set forth requirements for the safety systems whose source of power is the preferred power system. These criteria state that safety system redundancy shall be such that, for preferred power system operation (assuming standby power is not available), the system safety function can be accomplished assuming a single failure. To ensure that these requirements of the GDC identified above are satisfied, the electrical schematics of the systems required for reactor coolant makeup, residual heat removal, emergency core cooling, containment heat removal, containment atmosphere cleanup, and cooling water should be examined to ensure that the circuits from the preferred power system can supply redundant portions of these systems. If the minimum design required by GDC 17 is provided, the immediately available preferred circuit must be made available to the redundant portions of these systems. 4. All offsite power system equipment and components in the station switchyard and its connection to the onsite Class 1E system are reviewed to determine that they are appropriately included in the NPP quality assurance program. Safety-related equipment and components, and those required to support systems with accident mitigating functions, should have the appropriate quality classifications. The review should verify that procedures, maintenance, and surveillance tests associated with the equipment and components incorporate the appropriate quality controls. The organization responsible for quality assurance and maintenance should determine the adequacy of the quality assurance program. 5. To verify that the requirements (excluding seismic, tornado, and floods) of GDC 2 are satisfied for the facility being considered, the organization responsible for civil engineering and geosciences review should provide to the organization responsible for electrical engineering
