g. 2. GDC 4 is satisfied 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 and postulated accidents, as established in Chapter 3 of the SAR and reviewed by the organizations with primary responsibility for the reviews of plant systems, materials, and chemical engineering. 3. GDC 5 is satisfied as it relates to the sharing of SSCs of the ac power system and the following guidelines: A. RG 1.32, as it relates to the sharing of SSCs of the Class 1E power system at multi-unit stations. B. RG 1.81, as it relates to the sharing of SSCs of the ac power system, positions C.2 and C.3. 4. GDC 17 is satisfied 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. Acceptance is based on meeting the following specific guidelines: A. RG 1.6, as it relates to the independence of the onsite ac power system, Positions D.1, D.2, D.4, and D.5. B. RG 1.9 (see also IEEE Std. 387). C. RG 1.32 (see also IEEE Std. 308), as it relates to design criteria for onsite ac power systems. D. RG 1.53 (see also IEEE Stds. 279 and 603), as it relates to the application of the single-failure criterion to safety systems. E. RG 1.75 (see also IEEE Std. 384), as it relates to the onsite ac power system. 8.3.1-10 Revision 4 - May 2010 F. RG 1.153 (see also IEEE Std. 603), as it relates to criteria for electrical portions of safety-related systems. G. RG 1.155, as it relates to the use of onsite emergency ac power sources for SBO. H. RG 1.204 (see also IEEE Stds. 665, 666, 1050,
