SS program. This SRP section provides guidance for NRC reviewers to address functional design and qualification provisions and IST activities for RTNSS pumps, valves, and dynamic restraints in passive new reactors. As discussed in this SRP section, the IST program for pumps, valves, and dynamic restraints includes preservice and inservice testing of pumps and valves, and preservice and inservice examination and testing of dynamic restraints 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 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, valves, and dynamic restraints with safety-related functions.5 This SRP section also provides guidance for the assessment of the functional design and qualification of pumps, valves, and dynamic restraints with RTNSS functions in passive new reactors. SRP Section 3.10, “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment,” provides guidance for the assessment of the seismic and dynamic qualification of components. C. SRP Section 3.9.3, “ASME Code Class 1, 2, and 3 Components, and Component Supports, and Core Support Structures,” provides guidance for the assessment of the design and installation of safety and relief valves. D. Dynamic restraints 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.
