reviews the adequacy of administrative, maintenance, testing, and operating procedure programs. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 2, as it relates to the ability of dc power system SSCs to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, and floods, as established in Chapter 3 of the SAR and reviewed by organizations with primary responsibility for the reviews of plant systems, civil engineering and geosciences, and mechanical engineering. 2. GDC 4, as it relates to the ability of dc power system SSCs to withstand 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. 8.3.2-7 Revision 3 - March 2007 3. GDC 5, as it relates to sharing dc power system SSCs. 4. GDC 17, as it relates to (a) the capacity and capability of the onsite dc power system to enable the functioning of SSCs important to safety and (b) the independence and redundancy of the onsite dc power system in performing its safety function, assuming a single failure. 5. GDC 18, as it relates to the testability of the onsite dc power system. 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. 7. GDC 50, as it relates to the design of containment electrical penetrations containing circuits of safety-related and nonsafety-related dc power systems. 8. 10 CFR 50.63, as it relates to the ability of the onsite dc power system to support the plant in
