, inspection, and condition monitoring depending on the specific components and regulatory or code provisions and guidance implemented by the applicant or licensee. The specific areas of review are as follows: 1. Functional Design and Qualification of Pumps, Valves, and Dynamic Restraints A. The staff reviews system and component designs and equipment qualification provisions to ensure that pumps, valves, and dynamic restraints (snubbers) are designed, manufactured, tested, and installed to perform their applicable safety functions and to accommodate anticipated inservice examination or inspection and testing. B. This SRP section provides guidance for the assessment of the functional design and qualification of pumps and valves. SRP Section 3.10 provides guidance for the assessment of the seismic and dynamic qualification of pumps and valves. C. SRP Section 3.9.3 provides guidance for the assessment of the design and installation of safety and relief valves. D. Dynamic restraints (snubbers) for plant piping and components do not provide a load path or force transmission during normal plant operations, but function as rigid supports when subjected to dynamic transient loads. SRP Section 3.9.3 provides guidance for staff assessment of the design and qualification of snubbers. 2. Inservice Testing Program for Pumps A. The staff will review the descriptive information in the SAR covering the IST program for those ASME Code Class 1, 2, and 3 system pumps whose function is required for safety, as well as pumps not categorized as ASME Code Class 1, 2, or 3 but which the staff considers to be safety related. B. The staff will review procedures for testing for speed, fluid pressure, flow rate, and vibration at normal pump operating conditions. C. The staff will review test schedules and parameters for pumps that are operated continuously or routinely during operation, cold shutdown, or refueling operations (Group A pumps), and pumps that are not operated routinely except for
