titute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. To implement the requirements of the regulations identified above, the staff may use specific criteria, regulatory guides, and industry standards that provide information, recommendations, and guidance and in general describe an acceptable basis. SRP Section 3.9.3 defines 3.10-6 Draft Revision 4 – August 2015 acceptable load combinations and methods for combining dynamic responses for mechanical equipment. The same criteria are acceptable for electrical equipment. Paragraphs 1 and 2 below describe acceptable testing and analysis procedures for confirming the functionality of equipment for the defined load condition. These criteria, when satisfied, will fulfill the requirements of GDC 2 and 4, as discussed above, 10 CFR Part 50, Appendix B, Criterion XI, “Test Control”, and 10 CFR Part 50, Appendix S as they relate to the qualification of equipment. 1. The qualification of electrical equipment and its supports should meet the requirements and recommendations of American National Standards Institute/Institute of Electrical and Electronics Engineers (IEEE) Std. 344-2004, “IEEE Recommended Practice for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations,” as endorsed by the NRC in RG 1.100, “Seismic Qualification of Electric and Mechanical Equipment for Nuclear Power Plants.” Revision 31. (This revision of RG 1.100 provides guidance with exceptions for use of Appendix QR-A of ASME QME-1-2007 for seismic qualification of active mechanical equipment and other qualifications of mechanical components, and IEEE Std. 344-2004 for
