r Power Plant Piping Systems," and Part 7, "Requirements for Thermal Expansion Testing of Nuclear Power Plant Piping Systems." Under these GDCs, the staff reviews the treatment of dynamic responses of safety-related piping systems and reactor internal structures by the following procedures: 1. During the construction permit (CP) stage, the preliminary safety analysis report (PSAR) is reviewed for whether the applicant has made a commitment to conduct a piping steady-state vibration, thermal expansion, and operational transient test program. The applicant’s program description should be sufficiently comprehensive to contain all the elements of an acceptable program as described in subsection II.1 (Acceptance Criteria) of this SRP section. During the operating license (OL) stage, the final safety analysis report (FSAR) is reviewed to ensure that the applicant's PSAR commitment is fulfilled and the program is developed in sufficient detail. For DC and COL applications submitted under 10 CFR Part 52, the level of information reviewed should be consistent with that of a 3.9.2-26 Revision 3 - March 2007 FSAR submitted in an OL application. However, verification that the as-built facility conforms to the approved design is performed through the ITACC process. The reviewer should be assured that the applicant’s program as described in Sections 3.9.2 and 14.0 of the FSAR is sufficiently developed to: A. Establish the rationale and bases for the acceptance criteria and selection of locations for monitoring pipe motions. B. Provide the displacement or other appropriate limits at locations monitored. C. Describe the techniques and instruments (as needed) for monitoring or measuring pipe motions. D. Ensure that the staff will be provided documentation of any corrective action from the test and confirmation by additional testing to substantiate the effectiveness of the corrective action. 2. For seismic system analysis review, the following review procedures are implemented.
