UNIT 1 Date DSS 1.0 PURPOSE 1.1 The purpose of this test is to perform the following periodic inservice tests as required by Technicai 3pecifications and/or the ASME Boler & Pressure Vessel Code,Section XI, ' Rules for Inservice inspection d Nuclear Power Plant Components /
1.1.1 MontNy functional test of the Si pumps as per Technical Specification 15.4.5.II.A.1.
1.1.2 MontNy functional test of 1SI 825A&B, SI pump RWST suction valves, as required by Technical Specification 15.4.5.II.B.1.
1.1.3 MontNy functional test of 1SI-826A, B & C, Si pump BAT suc:lon valves, as required by Technical Specification 15.4.5.II.B.4.
1.1.4 Ouarterly full stroke test of 1SI 826B & C as required by ASME Section XI. This test wDI be performed montNy with 1.1.3 above.
1.1.5 Quarterly partial stroke of 1SI-889A&B, SI pump discharge check valves, as required by ASME Section XI. This test will be done montNy along with the pump -
test.
1.1.6 Ouarteriy full stroke of 1SI 891 A&B, Si pump mini-recire check valves, as required by ASME Section XI. TNs V Il be done montNy along with the pump test.
1.1.7 Quarteriy leak test of 1S18424 4B. recumulator discharge check valves, as required by ASME Section XI. This test w"i e done montNy dunng the pump test.
1.2 The functional test of the Si pumps also satisfies environmental qualification requirements.
2.0 PRECAUTIONS AND LIMITATIONS i.1 1f there is any problem in performing this test, immediately notify the duty shift superintendent.
Operation d this equipment is a Technical Specification requirement.
2.2 Monitor accumulator levels whle the SI pumps are running. A level increase wul Indicate leakage past the accumulator check valve, 2.3 Tne suction pressurr gaugR shall be isciated except for the time requimd to take readings.
2.4 There is no installed Instrumentation to measure the flow through 1SI 891 A or B, Si pump recirc line check valves. Satisfactory operation of an Si pumo for 15 minutes without overheating is positive indication that its respective recirc I!ne check vaive is operable.
2.5 Technical Specifications prohlblt the testinj # a safeguards component if the opposite train's diesel generator is out of service.
