general, the onsite ac power system is acceptable when it can be concluded that this system has the required redundancy, meets the single failure criterion, is protected from the effects of postulated accidents, is testable, and has the capacity, and capability, and reliability to supply 49 power to all safety loads and other required equipment in accordance with GDC General Design Criteria 2, 4, 5, 17, 18, and 50. Table 8-1 lists General Design Criteria (GDC), regulations, 50 51 regulatory guides, and branch technical positions used as the bases for arriving at this conclusion. The design of the ac power system is acceptable if the integrated design is in accordance with the following criteria and guidelines: 1. General Design Criterion 2 (GDC 2), as related to structures, systems, and 52 components of the ac onsite power system being capable of withstanding the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, and floods, as established in Chapter 3 of the SAR, and reviewed by the ASB and the Structural Engineering Branch (SEB)SPLB, the Civil Engineering and Geosciences Branch (ECGB), and EMCB as part of their primary review responsibility. 53 2. General Design Criterion 4 (GDC 4), as related to structures, systems, and 54 components 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 ASB, RSB and EQBSPLB and EMCB as part of their primary review responsibility. 55 3. General Design Criterion 5 (GDC 5), as related to the sharing of structures, 56 systems, and components of the ac power system and the following guidelines: a. Regulatory Guide 1.32 (see also IEEE Std 308), as related to the sharing of 57 structures, systems, and components of the ac power system. b. Regulatory Guide 1.81, as related to the sharing of structures, systems, and components of the ac power system,
