COOPER NUCLEAR STATION OPERATIONS MANUAL S VEILLANCE PROCEDURE 6.3.16.2 REC MOTOR OPERATED VALVE OPERABILITY TEST I.
PURPOSE A.
To provide a detailed instruction for station personnel to test oper-ability of motor operated valves of the reactor equipment coofing (REC) system.
II.
DISCUSSION A.
This procedure covers the operation necessary to assure proper operation of motor operated valves of the REC system.
It is written to operate all valves locally in order to bypass the interlocks between the valves.

All discrepancies shall be recorded in the Shift Supervisor's log.
2.
Attachment "A" shall be used to record the test and filed as part of the station records.
3.
All testing shall be coordinated with the Control Room Operator.
VI.
PRECAUTIONS A.
Ensure that no other testing is in progress prior to performing valve operability tests.
B.
Ensure that the REC system is returned to normal lineup per System Operating Procedure 2.2.65 at the completion of this test.
C.
Ensure that an Operator is present in Augmented Radwaste when closing REC-1329MV.
VII. TEST EQUIPMENT A.
None.

I. PROCEDURE
Note: All steps must be completed for monthly test. Only
- steps need be completed to prove operability for a system component being inop.
A.
Operate REC Valve From The Control Room As Follows.
- 1.
Open REC-711MV (south critical loop supply) and verify position.
- 2.
Close REC-711MV (south critical loop supply) and verify position.
- 3.
Open REC-714MV (north critical loop supply) and verify position.
- 4.
Close REC-714MV (north critical loop supply) and verify position.
Caution: When performing the test with one REC pump inoperable, do not secure the third REC pump. Maintain three pumps in service while cycling REC-721MV or REC-722MV to avoid having only two pumps in service and momentarily only one pump in service while REC-721MV or REC-722MV is closed.
- S.
Make sure REC pumps C and D are running and only one pump on the A and B side is running, then close REC-721MV (non-critical return) and verify position.
- 6.
Open REC-721MV (non-critical return) and verify position.
