oncludes that the relief valves in the ITAAC table meet the valve’s design set pressure, capacity, and overpressure; and each relief valve listed in the ITAAC table is provided with an ASME BPV Code Certification Mark that identifies the relief valve’s set pressure, capacity, and overpressure. (2) Pump and Valve Preoperational Testing. The ITAAC for in-situ testing of installed pumps and valves should verify their capability to perform their intended functions under the applicable 14.3.3−16 Draft Revision 1 – September 2018 fluid flow, differential pressure, electrical, and temperature conditions identified in the applicable system ITAAC. Standard ITAAC are provided in Appendix D to SRP Section 14.3 for verification of the performance of these pumps and valves. These ITAAC are summarized below: (a) Pump Preoperational Testing. (i) An ITAAC should verify pump capacity as part of preoperational testing. The Design Commitment should specify that the system’s safety-related pumps provide the design flow for removing design heat loads. The ITA should specify that a test will be performed of the system’s safety-related pumps. The Acceptance Criteria should specify that each system safety-related pump listed in the ITAAC table provides the design flow of at least (X) for removing design heat loads, while the system is aligned in an emergency operating lineup. (ii) An ITAAC should verify the Net Positive Suction Head (NPSH) for the applicable pumps as part of preoperational testing. The Design Commitment should specify that the system’s safety-related pumps have a net positive suction head available (NPSHA) that is greater than or equal to their net positive suction head required (NPSHR). The ITA should specify that a test will be performed of the system’s safety-related pumps. The Acceptance Criteria should specify that each system safety-related pump listed in the ITAAC table has an NPSHA that is greater than or equal to the NPSHR while the system is
