hstand seismic events. Regulations in 10 CFR Part 50, Appendix S apply to this SRP section because the reviewer evaluates seismic and dynamic test and evaluation programs for electrical and mechanical equipment, and associated supports, designated as important to safety. IEEE Std. 344-2004, as endorsed by RG 1.100, Revision 3, provides additional guidance for establishing acceptable seismic and dynamic test (or evaluation) qualification criteria for electrical and mechanical equipment and associated supports in nuclear power plants. The criteria are applied based on the seismic loads established for a particular site in accordance with 10 CFR Part 50, Appendix S. Meeting the requirements of 10 CFR Part 50, Appendix S provides assurance that seismic and dynamic qualification of mechanical and electrical equipment, and associated supports, designated as important to safety is performed in accordance with the criteria and standards (or their equivalent) cited in this SRP section, thereby ensuring that SSCs important to safety will perform acceptably when subjected to SSE loads and the equivalent effect of five OBE loads. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 3.10-17 Draft Revision 4 – August 2015 These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection I. 1. At the construction permit (CP) stage, the staff reviews the program described by the applicant in the PSAR for the qualification of mechanical, electrical, and instrumentation equipment and measures the program against the requirements listed in Subsection I of this SRP section. Of particular interest is the proper use of test and analytical, or the combination
