e 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 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 define 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, 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 (ANSI/IEEE) Std 344-1987 as endorsed by RG 1.100. 3.10-5 Revision 3 - March 2007 (Subsequent revision to RG 1.100 will provide 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 seismic qualification for Class 1E equipment.) These documents are generally applicable to all types of equipment and should be used to the extent practicable for the qualification of mechanical equipment. Specifically, conformance to the following criteria should be demonstrated. A. Qualification for Equipment Functionality i. Tests and analyses are required to confirm the functionality of all mechanical and electrical equipment during and after an earthquake of magnitude up to and including the OBE and SSE and for all static and dynamic loads from normal, anticipated operational occurrence, and accident
