his SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. Relevant requirements of GDCs 1, 2, 4, 14, and 15 are met if vibration, thermal expansion, and dynamic effects testing are conducted during startup functional testing for specified high- and moderate-energy piping and their supports and restraints. The purposes of these tests are to confirm that the piping, components, restraints, and supports have been designed to withstand the dynamic loadings and operational transient conditions encountered during service as required by the ASME BPV Code, and to confirm that no unacceptable restraint of normal thermal motion occurs. Test specifications should be in accordance with ASME OM-S/G-2012, “Standards and Guides For Operation of Nuclear Power Plants,” Part 3, “Requirements for Preoperational and Initial Start Up Vibration Testing of Nuclear Power Plant Piping Systems,” and Part 7, “Requirements for Thermal Expansion Testing of Nuclear Power Plant Piping Systems.” An acceptable test program to confirm the adequacy of the designs should include the following: A. A list of systems to be monitored. B. A list of the flow modes of operation and transients, such as pump trips and valve closures, to which the components will be subjected during the test. (For additional guidance, see RG 1.68). For example, the transients of the RCS heatup tests should include, but are not limited to, the following: (i) Reactor coolant pump start. (ii) Reactor coolant pump trip. (iii) Operation of pressure-relieving valves. (iv) Closure of a turbine stop valve. 3.9.2-15 Revision 4 – March
