ic restraints (snubbers) are provided in SRP Section 3.9.3. D. Acceptance criteria for the design and installation of safety and relief valves are provided in SRP Section 3.9.3. E. Acceptance criteria for the seismic and dynamic qualification of mechanical and electrical equipment are provided in SRP Section 3.10. 3.9.6-9 Revision 3 - March 2007 F. As required by GDC 14, safety-related valves that are part of the RCPB should be designed and tested such that these valves will not experience any abnormal leakage, or increase in leakage, from their loading, as addressed in SRP Section 3.10. G. For new plant applications, dynamic restraints in safety-related systems must include provisions to allow access for IST program activities. 2. Inservice Testing Program for Pumps A. The scope of the applicant’s test program is acceptable if it includes all of the ASME Code Class 1, 2, and 3 pumps described in 10 CFR 50.55a(f) and Subsection ISTA-1100 of the OM Code and, in addition, includes pumps not categorized as ASME Code Class 1, 2, or 3 but which the staff considers to be safety-related. Since the pump test program is based on the detection of changes in the hydraulic and mechanical condition of a pump relative to a reference test specified in Subsection ISTB-3000 of the OM Code, the establishment of a set of reference values and a consistent test method are basic criteria of the program. B. The pump test program is acceptable if it meets the requirements for establishing reference values and the periodic testing schedule described in Subsection ISTB-3000 of the OM Code. Subsections ISTB-3000, ISTB-5000, and ISTB-6000 of the OM Code establish the allowable ranges of IST quantities (e.g., flow rates and pressure differential), corrective actions, and vibration tests. The pump test schedule is required to comply with these rules. C. The frequency of ISTs and test parameters are acceptable if the provisions of Subsection ISTB-3000 of the OM Code are met. D. The methods of
