PRECAUTIONS AND LIMITATIONS

[ 1 2.1 Gland water flow to SW pump* bearings Should be maintained at Ž 1.5 gpm at all times. Maximum water flow to bearings is 15 gpm.

[1 2.2 Avoid pump runout; rated full load SW pump motor current Is 42 amps.

PROCEDURE 2.2.71 REVISION 69 PAGE 1 OF 47 II

[ ] 2.3 At river temperatures approaching 95*F, maintain REC HX outlet temperature below 98°F per Procedure 2.2.65.1.

[ ]2.4 Pump motor may draw high current due to silting if pump has not been operated for an extended period, such as following a pump rebuild. In addition, inadequate clearance between pump impeller and liner may cause pump motor-to draw high current. Per CR 94-0530 evaluation, pump motor may operate at a steady state current of up to 48 amps for a maximumobf 10 minutes after a cold motor start. If current does not lower to

  • 42 amps within 10 minutes from time pump.motor was started, remove pump.from service and wait at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> from time pump was stopped before attempting another start.

[]

2.5 Sealed valves shall be controlled per Procedure 2.0.2.

[ J 2.6 Observe following 4160V motor starting restrictions:

[ ]

NOTE.1 -A start is closure of motor supply breaker.

[ ] NOTE 2 -A cold motor is a motor which has been idle for at least'2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

[ I NOTE 3-A hot motor is a motor which has been energized within'last 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

[ ]

2.6.1 A motor shall be at a stop prior to a start attempt.

[]

2.6.1.1 A cold motor shall have no more than two Initial~start attempts. Each additional start shall be preceded by a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> wait.

[1 2.6.1.2, Ahot motor shall have no more than one initial start attempt. Each additional start attempt shall be preceded by a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> wait.

2.7 SW-STNR-A(B), SW ZURN STRAINERS, haVe an administrative out of service time of 10 days. If the out of service time cannot be met,. there, are no specific actions required. However, increased:Management involvement would be prudent to assist in swift resolution of problems which caused the out of service time to be exceeded.© 1

Z]

2.8 With a SW zurn strainer bypassed and SW System in its normal three pump configuration, pump rotation should be6alte'red to-keep two 'pUmps running in subsystem with operable strainer while swapping other two pumps as required.© I

DISCUSSION 1.1 FUNCTION 1.1.1 The SW System provides the ultimate'heat sink for equipment throughout the plant.

1.2 OPERATING CHARACTERISTICS 1.2.1 The SW System consists of four vertical SWpumps located in the Intake Structure with associated strainers, piping, valving, and instrumentation. The pumps discharge to a common header~from which independent Piping supplies:two Essential subsystems and one Non-Essential isubsystem. Automatic valving is provided to shut off all supply to the Nbn-Essentlal sdbsystem bn a drop in header pressure; thus, ensuring supply to the essential subsystems. Valves are included In-the common discharge headeri to permit the SW.System'.to be operated as two independent Essential subsystems.

Either subsystem can supply normal cooling water to 'the Non-Essential subsystem. Automatic valving also exists to split the Essential subsystems when high water level is,sensed in the Control Building Basement. The HXs and their valves are arranged such that they can be Individually backwashed without interrupting system operation.

1.2.2 The Essential subsystems supply the Co.ntrol Room air conditioner backup supply, Control Building Basement FCU backup supply, core flooding supply, DGs, REC HXs, SWBPS for the RRHR HXs, SW Gland Water System backup supply, and SWBP Gland Water System backup supply. The Non-Essential subsystem supplies CW System fill, CW Gland Water System backup supply,- Main Condenser bypass valve sparging, screen wash pumps, sparger pumps, and TEC HXs.

I PROCEDURE 2.2.71 REVISION 69 1

PAGE 42 OF 47

ATTACHMENT 2 INFORMATION SHEET 1.2.3 The SW Gland Water System consists of two subsystems, each.serving a pair-of SW pumps, with provisions for manually cross-connecting the subsystems. The normal supply to each subsystem is -from Service Water Systemdownstream of the SW strainers. A backup from the FP.System Will supply the Gland Water Subsystems if low pressure is sensed in either subsystem and a time delay has timed out. To be in compliance with 10CFR50, Appendix R, FP backup must be available to automatically supply the Gland Water Subsystems when the Riverwell System is supplying the Gland Water Subsystems. FP backup is not required to be in compliance with 10CFR50, Appendix R, When SW is supplying the Gland Water Subsystems.

The Riverwell System can also supply the.Gland Water Subsystems but must be manually aligned.

1.2.4 The SW pump lift settings are dependent upon gland water temperature. If SW pump ýgland water supply is transferred to another source, :the SW System Engineer must determine if pump lift settings are affected and lift adjustmnents need to be made. If-pump lift settings cannot be verified -to be correct for the temperature of the gland water supply, the affected SW pumps must be declared Inoperable.

1.2.5 Gland Water flow to the SW pump bearings should be maintained at 3 to 15 gpm, preferably In the high end of the band. Higher flows will help prevent sediment buildup'in the Gland Water System.

1.2.6 The following number of pumps (rated at 8000 gpm at 125' TDH) will be used during each of the indicated operating modes:

1.2.6.1 Normal;Operation; one to four (depending upon the TEC

.,HX cooling requirements).

1.2.6.2 Accident Conditions (LOCA); two (one from each critical bus).

1.2.6.3 Shutdown Conditions (normal); three.

1.12.7 To ensure that sufficient river flow is maintained through the REC HXs under all conditions, a balancing orifice is provided in tihe TEC HX inlet header upstream of the circulating water fill

'connection.
