1.0 PURPOSE 1.1 To insure coraliance with Technical Specification 4.0.5 which references ACME Section XI for testing of pumps.

ASME Section XI specifies test quantities to be me=sured and acceptable ranges for those quantities.

1.2 To insure ccmpliance with TMI Unit #2 iechnical Specifications, Se ction 4.0.5.a, which states:

Inservice testing of ASME Code Class 1, 2, and 3 pumps and valves shall be performed in accordance with Section XI of the ASME Soiler and Pressure Vessel Code and applicable addenda as required by 10 CFR50, Section 50.5Sa(g).

The above inservice testing will confirm the operation of the f::':,ing ASME Code Class 3 valves:

EF-V1 A and 3 and EF-V27 A and B and EF-V2 (CLOSED) 2.0 12:LIC23LE SURVEILL.2NCE FREQUENCY AND MODES 2.1 Eurveillance Frequency --

31 Jays (M) for the pump tests (2303-M273) 92 days (Q) for the valve tests (2303-M27A)

NOTE:

Subsection 6.1 of this procedure includes both valve and pump testing; subsection 6.2 includes pump testing only.

2.2 Modes

1 thru 4 - Testing required per ASME Section XI.

5 and 6 - Testing cptional per ASME Section XI.

3.0 LIMITS AND PRECAUTIONS 3.1 When a re erence value or set of values may have been affected by repair or routine servicing of the pump, a new reference value or set of values shall be determined, er the previous value reconfirmed by an inservice test run prior to or within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> after return of the pump to normal service.

Deviations between the previous and new set of reference values shall be identified and verification that the new values represent acceptable pump operation shall be placed in the Technical Spec 1fications surveillance file for that pump.

3.2 fc. inservice test shall be run on each pump nominally each month during normal plant operation.

It is reccmmended that this test frequency be maintained during cold shutdown periods where this can reasonably be accomplished, altncugh this is not mandatory.

3.3 Pumps that are operated more frequently than every conth need not be run or stcpped for a special test provided the quantities specified were measured, observed, and analyzed.

3.4 All test data must be analyzed within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> af ter test complet#on.

Revision 3 05/04/78 each pump shall be run for at least five minutes under conditions as stable as the system permits.

At the end of this time at leasc one measurement of each of the quantities specified shall be made and recorded.

3.6 The vibration probe must be placed in the same position each test to insure repeatable measurements. ;

3.7 Record identification of the instruments used on the Data Sheet.

3.8 Instruments used for measuring quantities shall not have a scale range exceeding four times the reference value.

3.9 If a valve is in an out of service system, it naed not be exercised until immediately prior to return of the system to service.

3.10 After a valve or its control system has either been replaced, repaired, or has undergonc mintenance that could affect its performance, and prior to the time it is returned to service, it shall be tested as necessary to demonstrate that the performance parameters which could be affected are within acceptable limits. Adjustment of stem ~

packing; removal of the bonnet, stem assembly, or actuator; or disconnection of hydraulic or electrical lines are examples of maintenance that could affect valve performance parameters.
