COMPONENTS REVIEW RESPONSIBILITIES Primary - Organization responsible for mechanical engineering reviews Secondary - None I. AREAS OF REVIEW This Standard Review Plan (SRP) section addresses the criteria, testing procedures, and dynamic analyses employed to ensure the structural and functional integrity of piping systems, mechanical equipment, reactor internals, and their supports (including supports for conduit and cable trays, and ventilation ducts) under vibratory loadings, including those due to fluid flow (and especially loading caused by adverse flow conditions, such as flow instabilities over standoff pipes and branch lines in the steam system) and postulated seismic events. Compliance with the specific criteria guidance in subsection II of this SRP section will provide reasonable assurance of appropriate dynamic testing and analysis of systems, components, and equipment within the scope of this SRP section in conformance with 10 CFR 50.55a; 10 CFR Part 50 Appendix A, General Design Criteria (GDCs) 1, 2, 4, 14, and 15; 10 CFR Part 50 Appendix B; and 10 CFR 52.47(b) and 10 CFR 52.80(a). 3.9.2-2 Revision 3 - March 2007 The specific areas of review are as follow: 1. Piping vibration, safety relief valve vibration, thermal expansion, and dynamic effect testing should be conducted during startup testing. The systems to be monitored should include: A. all American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code) Class 1, 2, and 3 systems, B. other high-energy piping systems inside Seismic Category I structures (the term, "Seismic Category I," is defined in Regulatory Guide (RG) 1.29), C. high-energy portions of systems whose failure could reduce the functioning of any Seismic Category I plant feature to an unacceptable safety level, and D. Seismic Category I portions of moderate-energy piping systems located outside containment. The supports and restraints necessary for operation during the life of the plant are considered to be parts
