1.0 Purpose

'Ib provide de r aflad instructicus to be followed in the event that there is a Service Water System failure such as punp trip, pump failure, pipe rupture, loss of ptmp sucticn, etc.

2.0 Irrlimticns to the Operator:

2.1 Service Water'Ptmp trip alarm on Panel SF/SF.

2.2 Iow se vice water pressure as indicated cn D_nel SF/6F (normal pressure is 55-60 psig) 2.3 Ibactor Bi41 ding Closed Cboling mter emnture increasing.

2.4 Turbine Bi41 ding Closed Cooling Water tr=,panture increasing.

3.2 Ibector Scram cm High Drywell Pressure of 2 psig.

4.0 Winte Operator Acticm:

4.1 Servi Water Pung Failure 4.1.1 Start standby service water pung or if a pung has tripped try to restart the service wcter pung that tripped out. .

4.1.2 If failure is caused by intake trash rack or screen blockage, reduce load with recire. flow and trip circulating water pumps as t

required to regain service water flow.

4.1.3 Shutdown and isolate the Peactor Cleanup Demineraliter System by tripping the cleanup punp in service and closing isolatien valves V-16-1 and V-16-61.
