ting the relevant requirements of the following Commission regulations: 1. GDC 2 as it relates to SSCs of the ac power system being capable of withstanding the effects of natural phenomena without the loss of the capability to perform their safety functions. 2. GDC 4 as it relates to SSCs of the ac power system being capable of withstanding the effects of missiles and environmental conditions associated with normal operation, maintenance, testing, and postulated accidents. 3. GDC 5 as it relates to sharing of SSCs of the ac power systems. 4. GDC 17 as it relates to the onsite ac power system's (a) capacity and capability to permit functioning of SSCs important to safety; (b) independence, redundancy, and testability to perform its safety function assuming a single failure; and (c) provisions to minimize the probability of losing electric power from any of the remaining supplies as a result of, or coincident with, the loss of power generated by the nuclear power unit or the loss of power from the transmission network. 5. GDC 18 as it relates to inspection and testing of the onsite power systems. 6. GDCs 33, 34, 35, 38, 41, and 44 as they relate to the operation of the onsite electric power system, encompassed in GDC 17, to ensure that the safety functions of the systems described in GDCs 33, 34, 35, 38, 41, and 44 are accomplished. 8.3.1-8 Revision 4 - May 2010 7. GDC 50 as it relates to the design of containment electrical penetrations containing circuits of the ac power system and the capability of electric penetration assemblies in containment structures to withstand a LOCA without loss of mechanical integrity and the external circuit protection for such penetrations. 8. Title 10 of the Code of Federal Regulations (CFR), Section 50.63, as it relates to the establishment of a reliability program for emergency onsite ac power sources and the use of the redundancy and reliability of diesel generator units as a factor in limiting the potential for SBO events. 9. 10
