Content:
t all structures, system and components important to safety should be designed and tested to assure that safety functions can be performed in the event of operational transients, earthquakes, and LOCA loadings. Under these guidelines, the staff reviews the treatment of dynamic responses of safety-related piping systems and reactor internal structures by the follow- ing procedures: 3.9.2-15 Rev. 2 - July 1981 1. During the CP stage, the PSAR is reviewed to assure 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 assure 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 devel- oped 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. Assure 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. 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 spectra, time history, equivalent static load) are reviewed to ascertain that the techniques
