Content:
on related to qualification of equipment important to safety will comply with established standards and criteria, thereby ensuring that such equipment will be capable of performing its intended safety functions. 7. Compliance with 10 CFR Part 50, Appendix S, requires that SSCs important to safety be designed to resist seismic events. 10 CFR Part 50, Appendix S applies 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. ANSI/IEEE Std 344-1987, as endorsed by Regulatory Guide 1.100, Revision 2, 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. 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 II. 1. At the CP stage, the staff reviews the program described by the applicant in the PSAR
