Description:
Restore Normal Charging and Letdown per procedure Abnormal Operating Procedure (AOP) 18007-C, Section B, Loss of Charging Flow RNO Step B8, using procedure 13006-1, CVCS Section 4.4.2.
Time Position Applicants Action or Behavior OATC 4.4.2 Returning Normal Charging and Letdown to Service OATC 4.4.2.1 IF a Charging Pump is NOT in service, Go To Section 4.4.13 to start the NCP OR an available Centrifugal Charging Pump, THEN Return To this section.
OATC 13006-C Section 4.4.13 CAUTIONS
- At BOL, while borating to maintain Tavg, the calculated delta boron concentration between the RCS and the last time the CCP/NCP was placed in service may be incorrect. Experience has shown that high concentrations of borated water tend to collect in the suction piping of the idle pumps, resulting in a higher boron concentration in the CCP/NCP than the RCS.
This may cause and unexpected boration and temperature reduction when the pump is placed in service or tested.
- Restart of a charging pump should not be delayed in order to flush the pump prior to start.
OATC 4.4.13.1 PRIOR to starting the pump and based on the conditions described in the first caution above, a slight boration should be anticipated and a briefing on compensatory actions to offset the boration should be conducted.
OATC CAUTION A determination should be made that loss of the Charging Pump was not due to air/gas binding before starting the same or another pump.

- CCP-1B or the NCP must be used for 120 gpm letdown. CCP-1A is only capable of flows up to 102 gpm at NOPT. It may not be used with 120 gpm letdown. At higher than normal RCS pressure, the flow will be reduced even more.
- Letdown temperature and pressure should be continuously monitored during the transfer. The Operator should manually intervene to control these limits during the transfer.

In the process of continuing the power ascension after transferring 4160V AC busses to the UATs, CVCS VCT Level Transmitter LT-112 Fails High.
Time Position Applicants Action or Behavior NOTE While letdown is configured for 120 gpm, the preferred flow path for Manual Makeup is through 1-FV-0110B BLENDER OUTLET TO CHARGING PUMPS SUCT. The design capacity of the VCT spray nozzles would be challenged with 120 gpm letdown in service and the addition of the makeup flow upstream of the VCT (1X6AH04-00024). This could prevent makeup from reaching the desired flow rate. Thus, 1-FV-0111B should only be used if 1-FV-0110B is not available.
