In the Boron Thermal Regeneration System, during the Boration Mode, why is the flow returning to the Volume Control Tank cooled? A. To cause oxygen to detrain from the liquid.B. To protect the Volume Control Tank from thermal stress.C. To make the boron flow easier.D. To protect the Reactor Coolant Pump seals from thermal stress.

Control room operators are investigating a potential malfunction of the Reactor Coolant Makeup system based on suspect indications following an RCS makeup evolution. The RO suspects the pot setting for BG-FK110, Boric Acid Blender Flow Control, may have been set wrong. RCS boron concentration is to be maintained at 500 ppm, with BAST boron concentration at 7000 ppm and all controls are in AUTO. The pot setting is at 2.74 turns.Is the pot setting correct and what indication is the RO using? A. No, the pot setting should be 2.14, Tave is increasing.B. Yes, the setting was correct, the batch counters did not operate correctly.C. Yes, the setting is correct, VCT makeup was not required.D. No, the setting should be 2.14, Tave is decreasing.

The plant is in MODE 5 preparing for a refueling.What condition could prevent operators from recognizing a dilution accident? A. Source Range Flux Doubled alarm card is removed.B. BG-LCV112A is in VCT position.C. BG-LCV112A, VCT divert valve is in AUTO.D. Source ranges are not in current calibration.

The plant is in MODE 3 normal alignment.If BG-LK149F, VCT level controller failed off-scale low, what (if any) effect would this have on the CVCS system and why? A. Divert to the RHUT, BG-112A is in AUTO.B. No effect, BG-LCV112A is in VCT position.C. Divert to the RHUT, even though BG-LCV112A is in VCT.D. No effect, BG112A is in AUTO position.

The plant is at 80% power with all systems in automatic. VCT level transmitter BG LT-149 has instrument tube blockage and fails at an indicated level of 49%. A subsequent RCS leak of 50 gpm develops.How will the Rod Control System respond with no operator action? A. Rods will step in due to PZR level/pressure decreasing.B. Rods will step in due to Turbine Runback OPDT.C. Rod control will be un-affected by these failures.D. Rods will step out due to boration of the RCS.

The plant is in MODE 5 and BG-V601, RMW to BA Blending F-10 Isolation, is unlocked and OPEN. Is this condition allowed by Technical Specifications? A. No, all dilution paths are required to be isolatedB. Yes, if an RCP is in operation.C. Yes, if BG-V0178 is locked closed.D. No, BG-V0601 is required to be locked closed.

The plant is in Mode 1. BN LCV-112D, Charging Pump Suction from RWST, is DNO'd closed for MOV maintenance. The following readings are noted.Temp. (?F)Level (%)BAT A6270BAT B7025RWST 5496What actions (if any) should the CRS take? A. Raise the temperature in BAT A to 65 degrees within 72 hours or initiate a PIR if temperature is NOT restored.B. Raise the level in the RWST to 97% within 1 hour or be in Hot Standby within the next 6 hours and in Cold Shutdown within the following 30 hours.C. Raise the level in BAT B to 40% within 72 hours or initiate a PIR if level is NOT restored.D. No action is required.

Which one of the following describes how the correct amount of boric acid is added to the combined makeup flow with the Reactor Makeup Control Mode Selector switch in the AUTOMATIC position. A. The Boric Acid flow controller uses an input from a boronometer.B. The addition flow rate is selected on the Boric Acid flow controller.C. The Boric Acid flow controller uses the integrated charging header flow signal.D. A sample analysis performed by Chemistry is fed to the Boric Acid flow Controller.

How is the Boric Acid System affected on the receipt of an SI signal? A. Both Boric Acid Transfer Pumps start and BG HV8104 opens.B. The Boric Acid Transfer pumps are load shed.C. No affect, all evolutions normally available are still available after an SI.D. The Boric Acid Transfer Pumps trip, but are available as needed.

Which of the following is the correct reason that the Dilute Mode takes longer to start diluting the RCS than the Alternate Dilute Mode? A. The transport time through the VCT slows the dilution.B. A maximum flowrate of 60 gpm can be achieved in the Dilute Mode.C. It takes longer to set up a dilution in the Dilute Mode than the Alternate Dilute Mode.D. The Alternate Dilute allows allows RMUW to enter the VCT only.
