4.1 MHEN starting a charging pump, THEN ensure component cooling water is being supplied to the oil cooler.
4 4.2 Immediately stop a centrifugal charging pump if any of the following occur:
- Oil leaving thrust bearing exceeds 160*F.
- Sudden drop in discharge pressure.
4
- Loss of component cooling water to a running pump.
- Lube oil pre.ssure drops to zero.

4.4 IE RCS temperature is greater than or equal to 200'F, THEN 4
the CCP Discharge Header FCV-121 Inlet Isolation valve for
\\
the pump NOT aligned to the charging header must be locked a
closed.
This does not apply during the time required to y
shift between CCPs.
- BG-V8483A for CCP A
- BG-V8483C for CCP B 4.5 MHEH any RCS cold leg temperature is less than 350*F, THEN only one CCP may be operable.
This does not apply during the time required to shift between CCPs or when the reactor vessel head is removed.
Refer to Technical Specification 3.5.3.
4.6 Each CCP's flow must be greater than or equal to 175 gpm for continuous operation.
By maintaining the recirc valve open and greater than 115 gpm charging flow, the CCP will remain in the continuous operations region.
Refer to Standing Order 17 for flow rates less than continuous flow values.
The time involved in switching pumps does not count toward the low flow cavitation limits. [ Commitment Step 3.2.1]
(}
4.7 IE instrument air is lost to BG FCV-121 OR BG HV-182 when both CCPs are running, THEN close either BG HIS-8105 or BG HIS-8106 and stop either CCP.
4.8 IE the PDP oil temperature is less than 70'F, THEN the PDP should be run on recirc until the oil temperature is greater than 70*F.
WHEN starting the PDP in emergency conditions, THEN the warmup to 70*F is not required.
The warmup to 70*F may be waived at any time by the SS/SO.

- Loss of component cooling water to a running pump.
- Lube oil pressure drops to zero.

the CCP Discharge Header FCV-121 Inlet Isolation valve for
\\
the pump NOT aligned to the charging header must be locked E
closed.
This does not apply during the time required to r
shift between CCPs.
- BG-V8483A for CCP A
- BG-V8483C for CCP B 4.5 WHEN any RCS cold leg temperature is less than 350*F, THEN only one CCP may be operable.
This does not apply during the time required to shift between CCPs or when the reactor vessel head is removed.
Refer to Technical Specification 3.5.3.
4.6 Each CCP's flow must be greater than or cqual to 175 gpm for continuous operation.
By maintaining the recire valve open and greater than 115 gpm charging flow, the CCP will remain in the continuous operations region.
Refer to Standing Order 17 for flow rates less than continuous flow values.
The time involved in switching pumps does not count toward
,s
(
the low flow cavitation limits. [ Commitment Step 3.2.1) 4.7 IE instrument air is lost to BG FCV-121 OR BG HV-182 when both CCPs are running, THEN close either BG HIS-8105 or BG HIS-8106 and stop either CCP.
4.8 IE the PDP oil temperature is less than 70*F, IHEN the PDP should be run on recirc until the oil temperature is greater than 70*F.
WHEN starting the PDP in emergency conditions, THEN the warmup to 70*F is not required.
The warmup to 70*F may be waived at any time by the SS/SO.
