UNIT 2 -
Date DSS 1.0 PURPOSE 1.1 The purpose of tNs test is to perform the following periodic inservice tests as required by Technical Specifications and/or the ASME Boler & Pressure Vessel Code,Section XI, " Rules for Inservice inspection of Nuclear Power Plant Components.*
1.1.1 MontNy functional test of the SI pumps as per Technical Specification 15.4.5. IIA 1.
1.1.2 MontNy functional test of 2SI-825A&B, Si pump RWST suction valves, as required by Technical Specification 15.4.5.II.B.4.
1.1.3 MontNy functional test of 2SI-826A. B & C. Si pump BAT suction valves, as required by Technical Specification 15.4.5.II.B.4.
1.1.4 Quarterly full stroke test of 2SI-826B&C as requir6d by ASME Section XI. This test wul be performed montNy with 1.1.3 above.
1.1.5 Quarterly partial stroke of 2SI 889A&B, Si pump discharge check valves, as required by ASME Section XI. This test wDI be done montNy along with the pump test.
1.1.6 Quarterly full stroke of 2SI-891 A&B, Si pump mini-recirc check valves, as required by ASME Section XI. This test wHI be done montNy along with the pump test.
1.1.7 Quarterly leak test of 2SI-842A&B, accumuiator discharge check valves, as required by ASME Section XI. This wul be dow montNy during the pump test.
1.2 The functional test of the Si pumps also satisfies environmental qualification requirements.
2.0 PRECAUTIONS AND LIMITATIONS 2.1 If there is any problem in performing this test, immediately notify the duty shift superintendent.
Opeution of this equipment is a Technical Specification requirement.
2.2 Monitor accumulator levels whHe the Si pumps are running. A level increase wUI indicate leakage past the accumulator check valve.
2.3 The suction pressure gauge shall be isolated except for the time required to take readings.
2.4 There is no installed instrumentation to measure the flow through 2SI 891 A or B. Si pump recirc line check valves. Satisfactory operation of a Si pump for 15 minutes without overheating is positive indication that its respective recirc line check valve is operable.
2.5 Technical Specification prohibits the testing of a safeguards component if the opposite trains diesel generator is out of service.
2.6 If at any time the pump suction pressure is less than the NPSH required, this test must be discontinued until the problem is corrected.
