ty. ANSI/IEEE Std 344-1987, as endorsed by Regulatory Guide 1.100, provides additional guidance for establishing acceptable seismic and dynamic test (or evaluation) qualification criteria for electric and mechanical equipment and associated supports in nuclear power plants. The criteria is applied based on the seismic loads established for a particular site in accordance with 10 CFR Part 100. Meeting the requirements of Section VI(a) of Appendix A to 10 CFR Part 100 provides assurance that seismic and dynamic qualification of mechanical and electrical equipment, plus 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 structures, systems, and components important to safety will perform acceptably when subjected to SSE loads and recurring loads equivalent to fractions of the SSE.64 III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below as may be appropriate for a particular case. The reviewer obtains and uses information from SRP Sections 3.7 and 3.9.2 and consults with SEB and MEB the ECGB as necessary to be assured 65 that the proper seismic and dynamic input motion is being used for the equipment qualification. For each area of review the following review procedures are used: DRAFT Rev. 3 - April 1996 3.10-16 1. At the CP or design certification stage, the staff reviews the program which the 66 applicant has described in the PSAR or Design Certification Application, respectively67 for the qualification of mechanical and electrical equipment. The program is measured against the requirements listed in subsection II. Of particular interest are the proper use of test and analytical procedures. Equipment which is too complex for reliable mathematical modeling should be tested unless the analytical procedures and corresponding design are convincingly conservative. Both the test and the
