Content:
t two separate circuits from the transmission network to the onsite Class 1E power distribution system are provided, adequate physical and electrical separation exists, and the system has the capacity and capability to supply power to all safety loads and other required equipment. Table 8-1 of SRP Section 8.1 lists GDCs, RGs, standards, and branch technical positions (BTPs) utilized as the bases for arriving at this conclusion. Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 2, found in Appendix A to 10 CFR Part 50, as it relates to SSCs of the offsite power systems being capable of withstanding the effects of natural phenomena (excluding seismic, tornado, and flood) without the loss of the capability to perform their safety functions. 8.2-6 Revision 5 - May 2010 2. GDC 4 as it relates to SSCs of the offsite power systems being protected against dynamic effects, including the effects of missile that may result from equipment failures during normal operation, maintenance, testing, and postulated accidents. 3. GDC 5 as it relates to sharing of SSCs of the preferred power systems. 4. GDC 17 as it relates to the preferred power system's (i) capacity and capability to permit functioning of SSCs important to safety; (ii) 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 loss of power from the onsite electric power supplies; (iii) physical independence; (iv) availability. 5. GDC 18 as it relates to inspection and testing of the offsite power systems. 6. GDCs 33, 34, 35, 38, 41, and 44 as they relate to the operation of the offsite 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. 7. 10 CFR 50.63 as it relates to an AAC power source (as defined in 10 CFR 50.2)
