S2.OP-SO.CVC-0002(Q)
Salem 2 Page 5 of 69 Rev. 38 3.8 Centrifugal Charging Pumps:
3.8.1 A maximum of one Centrifugal Charging Pump OR one Safety Injection Pump shall be OPERABLE when the temperature of one or more of the RCS cold legs is #312°F, with the reactor vessel head installed. However, a second pump may be aligned for testing purposes only, provided the pump is verified in a recirculation flowpath with the manual discharge valve closed prior to aligning the motor circuit breaker to the electrical power circuit. (TSSR 4.5.3.2.b).
3.8.2 The design flowrate of the Centrifugal Charging Pumps is 150 gpm.
3.8.3 The Centrifugal Charging Pump Speed Increaser Oil Pump should be primed before starting the pump after maintenance activities.
3.8.4 Two boration flow paths are required in Modes 1-3.
When 2CV55 is isolated, 2CV81 OR 2CV82 must be throttled, with $33 gpm (as verified by Charging/Letdown mismatch),
AND 2CV48 and 2CV53 must be locked open, to satisfy boration flowpath requirements for Centrifugal Charging Pumps.
3.8.5 The Control Air Supply to 2CV55 Bypass Valve (2CA2015), which provides full closure capability for the 2CV55 valve, does NOT have a bumpless transfer feature.
Charging Flow should be verified to be above the minimum flow setpoint prior to manipulating the 2CA2015 valve.
3.8.6 Whenever a Centrifugal Charging Pump Recirc Valve (2CV139 or 2CV140) are CLOSED with a Centrifugal Charging Pump in service Charging flow must be maintained >100 gpm on 2FE128.
3.8.7 Centrifugal Charging Pump Casing Drain Line blank flange should be installed prior to pump operation.
3.8.8 When a Centrifugal Charging Pump is started, the Auxiliary Oil Pump will start and run until the shaft driven oil pump develops 12 psig.
When the charging pump is shutdown, the Auxiliary Oil Pump will start at 8 psig and run until the time delay relay times out. However, it should be noted that after the charging pump breaker is made ready, the Auxiliary Oil Pump will AUTO start and continue to run until the oil pump circuit is reset. By design, the circuit is reset when the charging pump is started and the shaft driven oil pump develops 12 psig
[80014165].
3.8.9 Upon shutdown of a centrifugal charging pump the verification of auxiliary oil pump operation should be timely, since it only operates for.1 minute.
3.8.10 Centrifugal Charging Pump operability is NOT affected by unavailability of the associated Auxiliary Oil Pump.
S2.OP-SO.CVC-0002(Q)
Salem 2 Page 6 of 69 Rev. 38 3.9 23 Charging Pump (Positive Displacement Pump):
3.9.1 23 Charging Pump shall be aligned to Unit 1 OR the pump shall be C/T when 21 or 22 Safety Injection Pump is capable of injection into the core with RCS temperature #312°F with the Reactor Vessel Head installed.
[C0565]
3.9.2 23 Charging Pump Variable Speed Unit oil temperature should be maintained between 110°F and 150°F.
3.9.3 Do NOT operate 23 Charging Pump with suction pressure <31.8 psig, when aligned from the VCT OR <5.0 psig when aligned from the RWST.
3.9.4 The design flowrate of the 23 Charging Pump is 98 gpm (at 130°F & 2500 psig).
3.9.5 23 Charging Pump does NOT receive a trip signal from a SEC MODE I actuation (Accident Loading).
3.9.6 The following precautions are applicable for starting 23 Charging Pump after mechanical maintenance:
Health Physics is notified prior to filling and venting pump.
Handling of radioactive liquids must be done IAW NC.NA-AP.ZZ-0024(Q) Radiological Safety Program.
Suitable hose is available to direct liquid to a poly bottle.
3.9.7 23 Charging Pump is required to be capable of being cross tied to Unit 1 CVCS charging header from the Unit 2 RWST to provide a Post-Fire Safe Shutdown Function IAW10CFR Part 50 Appendix R Regulation whenever Unit 1 is in Modes 1-4.
3.9.8 When operating 23 Charging Pump on recirc to RWST do NOT exceed 1700 rpm on Output Fluid Drive as indicated on the hand held tachometer.
[OE 17609]
3.9.9 23 Charging Pump provides a support function to maintain the CVC Cross-Connect System available in compliance with 10CFR50 Appendix R whenever Unit 1 is in Modes 1-4. SH.OP-AP.ZZ-0108(Q), Operability Assessment and Equipment Control Program, provides Safe Shutdown Administrative Controls for an unavailable CVC Cross-Connect System.
3.9.10 When performing 23 Charging Pump fill and vent IAW Section 5.10, Restoration of 23 Charging Pump After Mechanical Maintenance, it should be noted that vent valves 2CV470 and 2CV471 are located in the Unit 1 Charging Valve Alley. Failure to operate the appropriate units vent valves in Step 5.10.7H, 5.10.7H.6, 2.1.2G or Attachment 4 (i.e., incorrectly operating valves 1CV470 and 1CV471 which are located in the Unit 2 Charging valve Alley) will result in loss of Unit 2 VCT level during performance of the system fill and vent.

S2.OP-SO.CVC-0002(Q)
Salem 2 Page 7 of 69 Rev. 38 3.9 (continued) 3.9.11 When performing 23 Charging Pump packing break-in IAW Section 5.10, Restoration of 23 Charging Pump After Mechanical Maintenance, observe the following:
2CV141 relief valve is set at.2735 psig (P&ID 205328).
Excessive throttling of 2CV485 OR 2CV486, PDP RECIRC TEST LINE ISOLATION VALVES, has the potential to lift 2CV141 discharge relief to the VCT. This could result in a reactivity excursion during power operation.
Valve throttling must be performed slowly to prevent lifting of 2CV141.
VCT level is to be monitored carefully for indications of 2CV141 lifting (unexpected VCT level rise or flow noise).
23 Charging Pump is be stopped immediately and 2CV485 AND CV486 are to be closed when 2CV141 is suspected of lifting.
3.9.12 Due to potential back leakage through the 2CV63 and 2CV64 valves, 23 Charging Pump suction piping is susceptible to overpressurization anytime 2CV57 is closed with the pump stopped. The Operator should closely monitor pump suction pressure (2PI192C) to ensure suction pressure is maintained within its normal operating range until suction pressure has stabilized at <100 psig (2PI192C). An Engineering Evaluation is required anytime pump suction pressure is suspected of exceeding 225 psig.
3.9.13 23 Charging Pump is NOT designed to pump air.
[70052001]
The pump internal (piston) suction valves may be damaged when the system is NOT properly filled and vented. Air voids in the pump suction/discharge piping could result in other adverse conditions such as charging flow oscillations and water hammer. For these reasons, Outage Services is to perform Ultrasonic Testing (UT) of affected pump suction and discharge piping to ensure proper fill and vent with no air voids.
When the UT examination indicate the presents of air voids in the pump suction header path or recirculation header path, the applicable section(s) of Attachment 4 are to be performed to eliminate the air voids.
There are two high points in the pump discharge piping that physically cannot be filled and vented. When UT examinations indicate the presents of air voids in these two sections of piping, the pump is to be placed in recirc with the RWST for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at the highest possible flowrate to sweep the air into the RWST.
