es 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."55 Under these guidelinesGeneral Design Criteria , the staff reviews the treatment of dynamic 56 responses of safety-related piping systems and reactor internal structures by the following procedures: 1. During the CP stage, the PSAR is reviewed to assureensure that the applicant has provided a commitment to conduct a piping steady-state vibration, thermal expansion and operational transient test program. The applicants program description should be sufficiently comprehensive to contain all the elements of an acceptable program as described in subsection II.1 of this SRP section. During the OL stage, the FSAR is reviewed to assureensure that the applicant's PSAR commitment is fulfilled and the program is developed in sufficient detail. The reviewer should be assured that the applicants 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 to monitor pipe motions. b. Provide the displacement or other appropriate limits at locations to be monitored. c. Describe the techniques and instruments (as needed) for monitoring or measuring pipe motions. d. AssureEnsure that the NRC will be provided documentation of any corrective action resulting from the test and conformation by additional testing that substantiates effectiveness of the corrective action. 3.9.2-21 DRAFT Rev. 3 - April 1996 2. For seismic system analysis review, the following review procedures are implemented. a. Seismic Analysis Methods For all Category I systems, components, equipment and their supports (including supports for conduit and cable trays, and ventilation ducts), the applicable methods of seismic analysis (response
