DIESEL GEt4ERAf0R kULL OlL IR<GSEER PUMP 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 A.

Diesel fuel oil is stored in two underground tanks. Diesel generator 4

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.

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.

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).

8.

Record the flow meter indication.

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.

12. Close valve DGDO-11 (DGDO-15).

r 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 18.

Return the flow meter to the tool c' rib.
