trumentation grounding systems. The EPRI Evolutionary Plant Utility Requirements Document, Chapter 11, Section 9 (Reference 22) provides acceptable guidelines for the design and performance of station grounding systems and surge and lightning protection systems.67 2. To assure ensure that the requirements of General Design Criterion GDC 18 are satisfied, the electrical schematics should be examined to determine that the design includes provisions for testing the transfer of power to the onsite distribution system from the main generator supply to the preferred power system, or to any other supply. It should also be established that the circuitry required to perform these transfer functions has the capability of being tested during plant operation . PTRBHQMB will review 68 69 preoperational and initial startup test procedures. QABHQMB will also review the 70 71 periodic test procedures. 3. General Design Criteria 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 assure ensure that these requirements of the General Design Criteria identified above are satisfied, the electrical schematics of the systems required for reactor coolant makeup, residual heat removal, emergency core cooling, containment heat removal, 8.2-13 DRAFT Rev. 4 - April 1996 containment atmosphere cleanup, and cooling water should be examined to assure ensure that the circuits from the preferred power system can supply redundant portions of these systems. If the minimum design required by General Design Criterion GDC 17 is provided, the immediately available preferred circuit must be made available to the redundant portions of these systems. 4. It should be determined that all equipment from and
