with written procedures, and the maintenance of sufficient records as evidence of quality assurance activities, respectively. Criterion III specifically requires that a test program used to verify the adequacy of a specific design feature shall include suitable qualification testing of a prototype unit under the most adverse design conditions. o 10 CFR Part 50, Appendix S, “Earthquake Engineering Criteria for Nuclear Power Plants,” requires that SSCs important to safety be designed to “withstand the effects of natural phenomena, such as earthquakes, without loss of capability to perform their safety functions.” • 10 CFR Part 52 governs the issuance of early site permits, standard design certifications, combined licenses, standard design approvals, and manufacturing licenses. Part 52 specifies, among other things, that contents of some applications must satisfy the requirements of 10 CFR Part 50, Appendix A, Appendix B, Appendix S, and 50.55a. Related Guidance • NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition” (Ref. 5), provides guidance to the NRC staff in performing safety DG-1412 Page 3 reviews under 10 CFR Part 50 and 10 CFR Part 52. Specifically, Section 8.3.1, “A-C Power Systems (Onsite),” Section 8.3.2, “D-C Power Systems (Onsite),” and Section 3.11, “Environmental Qualification of Mechanical and Electrical Equipment,” contain review guidance related to the environmental qualification of safety-related electrical equipment. Section 3.10, “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment,” contains review guidance for the seismic qualification of electrical equipment in the event of a seismic occurrence. • RG 1.100, “Seismic Qualification of Electrical and Active Mechanical Equipment and Functional Qualification of Active Mechanical Equipment for Nuclear Power Plants” (Ref. 6), discusses, in part, the seismic qualification of
