Content:
by the ASME Boiler and Pressure Vessel Code (ASME B&PV Code) Section III (Ref. 13), (2) other high energy piping systems inside Seismic Category I structures, (3) high energy portions of systems whose failure could reduce the functioning of any Seismic Category I plant feature to an unacceptable level, and (4) Seismic Category I portions of moderate energy piping systems located outside containment. In addition, inspections or testing may be conducted for flow-induced vibration loads on components that must maintain their structural integrity to avoid damage to safety-related SSCs. The SSCs and tests listed in Sections A-1.a. through A-11.p. below are representative of the plant features that should undergo preoperational testing. This list is provided to indicate the extent of testing necessary to demonstrate that the facility can be operated in accordance with design requirements. In general, the tests listed below make no distinction between boiling water reactors (BWRs) and pressurized water reactors (PWRs). An applicant may combine tests of items listed in this appendix and should include preoperational tests of the listed SSCs as appropriate for the facility. Preoperational tests should not be limited to the list provided below because additional or different tests may be dictated by the particular plant design or the nomenclature applied to plant systems and features. A-1.a. Reactor Coolant System The reactor coolant system (RCS) includes all pressure containing components (such as pressure vessels, piping, pumps, and valves) within the reactor coolant pressure boundary, as defined in 10 CFR 50.2, “Definitions.” 1. Integrated Systems Tests. Perform expansion and restraint tests to confirm the acceptability of clearances and displacements of vessels; piping; piping hangers; and seismic and other hold down, support, or restraining devices in the as built system during normal hot functional testing plant conditions. The system should be subjected to hot
