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.

Service Water Motor Operated Valve Operability Test.

  • 1.

Secure the screen wash and sparger pumps.

  • 2.

Close SW-117MV (Turbine Building service water supply) and reopen immediately.

~

Caution: The Operator should stand by to open SW-117MV manually if it fails to open.

3.

Close SW-116MV (screen wash priming and emergency supply) and reopen.

4.

Check SW-36 (service water pump crosstie) open.

  • S.

Close SW-37MV (service water pumps crosstie) and reopen.

  • 6.

Restart the screen wash.and sparger pumps and check proper screen 4

operation.

7.

Close the valves to the operable gland seal water strainers.

a.

SW-544 (S-403) inlet valve.

b.

SW-556 (S-405) inlet valve.

8.

Check closed SW-551 (S-404) inlet valve.

t 9.

Open SW-2128MV (service water gland seal water backup from service water pumps A and C) and reclose (return the switch to the AUTO position af ter closing the valve).

10. Open' SW-2129MV (service water gland seal water backup from service water pumps B and D) and reclose (return the switch to the AUTO

-position after closing the valve).

11.

Open the valves to the operable gland seal water strainers.

a.

SW-544 (S -403) inlet valve.
