te quality standards commensurate with the importance of the safety functions to be performed. B. General Design Criterion 2 and Appendix A to 10 CFR Part 100 as they relate to qualifying equipment to withstand the effects of natural phenomena such as earthquakes. C. General Design Criterion 4 as it relates to qualifying equipment being capable of withstanding the dynamic effects associated with external 3. 10-2 Rev. *2 - July 1981 missiles and internally generated missiles, pipe whip, and jet impinge- ment forces. D. General Design Criterion 14 as it relates to qualifying equipment associated with the reactor coolant boundary so as to have an extremely low probability of abnormal leakage, of rapidly propagating failure and of gross rupture. E. Appendix B to 10 CFR Part 50 as it relates to qualifying equipment using the quality assurance criteria provided. Specific criteria, regulatory guides, and industry standards that provide information, recommendations and guidance, and In general describe a basis. acceptable to the staff that may be used to implement the requirements of the regulations identified above are as follows. Acceptable load combinations and methods for combining dynamic responses for mechanical equipment are defined in SRP Section 3.9.3. The same criteria is acceptable for electrical equipment. Acceptable testing and analysis procedures for confirming the operability of equipment for the defined load condition are presented in paragraphs 1 and 2 below. These criteria, when satisfied, will fulfill the requirements of GDC 2 and 4, as discussed above, and paragraphs XI of Appendix B to 10 CFR 50 and VI (a)(1) and (2) of Appendix A to 10 CFR Part 100 as they relate to the qualification of equipment. 1. For plants for which the CP application was docketed after October 27, 1972, the qualification of electrical equipment and their supports should meet the requirements and recommendations of IEEE Std. 344-1975 and the Regulatory Position of Regulatory Guide
