SUMMARY

! + This is a Minor Revision.

1 4 Step 2.2; Changed to conditaonal step for apphcation when starting pumps. )

+ Step 3.2; Co..wEd cunent value to less than overcurrent protection.

J

+ Steps 5.2.5 and 5.3.3; Changed to eaadhinnal steps for "two or more Circulating Water Pumps are O/S". l 1

+ Attachment 1; Deleted as redundant to requirements of Abnormal Operating Procedure on loss of two or more circulating water pumps.

, S1.OP-SO.CW-0001(Z) 1.0 PURPOSE 1.1 To provide instructions - ry to:

1.1.1 Start, stop, and emergency trip Cimulating Water Pumps.

1.1.2 Supply and secure cr.wgs.cy Bearing I.mbrication flow to Circulating Water Pumps.

1.2

  • Ibis penrwhne is applicable in any Mode.

2.0 PREREQUISITES l 2.1 Components "Off Normal and Off Normal Tagged" list (s) has been reviewed for the system and support system (s) associated with the evolution to be performed a '

this procedme 2.2 IE starting Circulating Water Pumps,  :

THEN for the applicable pump (s): l 2.2.1 Screen Wash Pumps and Traveling Screens are available.

2.2.2 Intake Structure stop logs are removed.

2.2.3 I

{ All Condenser inspection doors and waterbox openings are closed with all closure bolts tightened i 2.2.4 Water boxes are primed.

2.2.5 Bearing Lube System is operating and supplying flow to pump motors.

.O PMCAUTIONS AND LIMITATIONS 3.1 Multiple starts of Circulating Water Pumps may result in deterioration of the pump motor windings. SC.OP DD.ZZ-OD03(Z), Large Motor Starting Criteria, contains the statting restrictions for operation of the Circulating Water Pumps.

3.2 DO NOT allow Circulating Water Pump motor current to excmd =330 amps. j 4.0 EOUIPMENT/MATNAL REOUIRED None l
