REVIEW RESPONSIBILITIES Primary - Mechanical Engineering Branch (MEB) Secondary - None I. AREAS OF REVIEW MEB reviews the criteria, testing procedures, and dynamic analyses employed to assure the structural and functional integrity of piping systems, mechanical equip- ment, reactor internals, and their supports under vibratory loadings, including those due to fluid flow and postulated seismic events to assure conformance with General Design Criteria 1, 2, 4, 14 and 15. The staff review covers the following specific areas: 1. Piping vibration, thermal expansion, and dynamic effect testing should be conducted during startup testing. The systems to be monitored should include (a) all ASME Code Class 1, 2, and 3 systems, (b) other high-energy piping systems inside Seismic Category I Structures, (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 of the piping system. The purpose of these tests is to confirm that these piping systems, restraints, components, and supports have been adequately designed to withstand flow-induced dynamic loadings under the steady-state and operational transient conditions anticipated during service and to confirm that normal thermal motion is not restrained. The test program description should include a list of different flow modes, a list of selected locations for visual inspections and other measurements, the accep- tance criteria, and possible corrective actions if excessive vibration or indications of normal thermal motion restraint occurs. 2. The following areas related to the seismic system analysis described in the applicant's safety analysis report (SAR) are reviewed. l Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review
