Content:
ng; 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 and/or cold testing with simultaneous operation of auxiliary systems. 2. Component Tests. The following RCS components should undergo appropriate tests and measurements: a. pressurizer, including pressurizer heaters and pressurizer spray and throttle valves (PWR); Appendix A to DG-1259, Page A-3 b. pumps, motors, and associated power sources; c. steam generators (PWR); d. pressure relief valves, block valves, and associated dump tanks, as well as supports and restraints for discharge piping; e. main steam isolation valves; f. other valves; g. instrumentation used to monitor system performance or perform permissive and prohibit interlock functions; h. reactor vessel and reactor internal vent valves; i. safety and relief valves including testing of acoustic monitors used to detect leakage downstream from safety and relief valves; j. jet pumps; k. heat exchangers; and l. pyrotechnic-actuated squib valves. 3. Vibration Tests. The reactor internals1 and other components, such as piping systems, heat exchangers, and rotating machinery should undergo vibration testing. 4. Pressure Boundary Integrity Tests. All pressure boundaries should be subjected to hydrostatic tests to obtain baseline data for subsequent inservice inspection and testing. A-1.b. Reactivity Control Systems 1. Control Rod System Tests: a. Demonstrate normal operation and reactor trip or scram capability of the control rods and control rod drive system. b. Demonstrate proper operation of functions such as control rod withdrawal inhibit features, runback features, rod withdrawal sequence control devices, and rod worth minimizers. c. Demonstrate proper operation of rod position instrumentation and proper interaction of the control rod drive system with other systems and design features, such as automatic
