23-1974 (endorsed with exceptions by the NRC in RG 1.89, “Environmental Qualification of Certain Electric Equipment Important to Safety for Nuclear Power Plants”). The IEEE Std. C37.98-2013 is, in general, acceptable to the NRC staff for the seismic qualification testing of protective relays and auxiliaries. 2. Instrumentation described in RG 1.97, including associated mountings, should be tested under appropriate seismic and dynamic loadings as described in the regulatory guide, thereby ensuring that the instruments will continue to monitor plant variables and systems after a seismic event and/or accident. 3. If the applicant proposes qualification by an experience-based approach, the details of the experience database, including applicable implementation methods and procedures to ensure structural integrity and functionality of the in-scope mechanical and electrical equipment, must meet the functionality of equipment for the defined load condition as presented in paragraphs 1 and 2 above. Supporting documentation for equipment 3.10-11 Revision 4 – December 2016 identified in the database should confirm that such equipment remained functional during and after an SSE and the equivalent effect of five postulated occurrences of OBE in combination with other relevant static and dynamic loads. Additional guidelines to determine the adequacy of an applicant’s proposal to qualify equipment by earthquake and/or test experience approaches are detailed in RG 1.100. 4. GDC 1 and 10 CFR Part 50, Appendix B, Criteria XVII, “Quality Assurance Records,” establish requirements for records concerning the qualification of equipment. To satisfy these requirements, complete and auditable records must be available, and the applicant must maintain them, for the life of the plant. These files should describe the qualification method used for all equipment in sufficient detail to document the degree of compliance with the criteria of this SRP section. These records should be
