, SURVEILLANCE PROCEDURE 6.3.12.8 FLOW TEST

, s a

I. PURPOSE

A. To provide a detailed instruction for station personnel to perform a flow test of the diesel generator fuel oil transfer pumps.

l II. DISCUSSION 4

A. Diesel fuel oil is stored in two underground tanks. Diesel generator fuel oil transfer pumps A and B transfer fuel to day tanks in the Diesel Rooms. Either pump can feed the day tank in DG-1 Room, or DG-2 Room, or both.

IV. PREREQUISITES A. Obtain permission and signature from the Shift Supervisor before starting the test.

B. Schedule this test to follow a monthly diesel operability test. This will provide a means for lowering the day tank to a level necessary to assure full transfer pump flow. ,

C. Coordinate testing with the Control Room Operator.

I. PROCEDURE

4 A. Diesel Generator Fuel Oil Transfer Pu'ap Flow Test.

I

1. Obtain the Shif t Supervisor's signature.

l

2. Record the levels in diesel oil storage tanks A and B.
3. Place the switches for both fuel oil transfer pumps A and B in off l , prior to starting the diesel generators for the monthly operability  ;

test when this procedure is to be performed.

} Note: Both switches must be in the OFF position since either pump

j. will start on a low level in either day tank. .

)

) 4. Close valve DCDO-11 (DGDO-15) and return the broken seal to -the

! Shift Supervisor.

i [

! 5. Close valve DGDO-19 (DGDO-19) and return the broken seal to the

[ Shift Supervisor.

6. Install the flow meter in the fill line near the top of the day

! tank.

t I 7. To assure maximum transfer pump flow rates can be measured, verify t

that the day tank levels are < 40" prior to starting and record the

level in day tank 1 (2).

i l 8. Record the flow meter indication.

) 9.' Open valve DGDO-ll (DCDo-15).

10. Start fuel oil transfer pump A (B) and operate it for 5 minutes.

During operation record transfer pump A (B) discharge pressures as indicated on DGDO-PI-634A (DGDO-PI-634B) and DGDO-PI-636A (DGDO-PI-636B).

11. Stop transfer pump A (B) and record the flow meter indicatibn.

r

12. Close valve DGDO-11 (DGDO-15).
13. Remove the flow meter and return the fill line back to normal.
14. Open valve DGDO-11 (DGDO-15) and install the new seal as issued by

, the Shift Supervisor.

15. Open valve DGDO-19 (DGDO-19) and install the new seal as issued by the Shift Supervisor.

~

16. Perform independent (Licensed Operator) verification that the valves closed in Steps 4. and 5. have been reopened and sealed.,

i 17. Place one transfer pump control switch in AUTO and the other in AUTO ALTERNATE.

i 1 18. Return the flow meter to the tool c' rib.

19. Notify the Shift Supervisor thnt the test is completed.
