l 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." Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. GDC 1 requires that systems and components important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions performed. Vibration, thermal expansion, and dynamic effects tests are described in this SRP section for startup functional testing of specified high-energy and moderate-energy piping and 3.9.2-24 Revision 3 - March 2007 their supports and restraints. Guidance is provided herein and in RG 1.20 for analysis of vibration of reactor internals. These vibration analyses are confirmed by prototype testing. Dynamic analyses methods are described in this SRP section for all seismic Category 1 systems, components, equipment, and their supports (including supports for conduit and cable trays, and ventilation ducts). Compliance with the requirements of GDC 1 provide assurance that systems and components within the scope of this SRP section are capable of performing their intended safety functions. 2. GDC 2 requires that systems and components important to safety be designed to withstand the effects of expected natural phenomena combined with effects of normal and accident conditions without loss of capability to perform their safety functions. Vibration testing, dynamic analyses, and suitable comparisons are described in this SRP section for systems and components important to safety. The tests, analyses, and comparisons are in accordance with sound engineering practices and provide assurance that these systems and components are designed to withstand natural phenomena in combination with normal and accident conditions.
