-The Pressurizer Manway is ON.
-Steam Generators are available for heat removal.
-Train ‘A’ 4kV Bus PBA-S03 is de-energized due to a bus fault.
Subsequently:
-The Train ‘B’ LPSI pump is continuously oscillating between 50 and 60 amps and SDC flow is oscillating between 4200 and 4600 gpm
-The CRS has entered 40EP-9EO11, Lower Mode Functional Recovery, and is addressing HR-2, SDC.

C. (1) raise SDC flow to 5000 gpm (2) secure the ‘B’ LPSI Pump, then GO TO HR-3, Natural Circ.
D. (1) raise SDC flow to 5000 gpm (2) perform Standard Appendix 240, LM-Placing Train B CS on SDC

Answer 20

A. (1) lower SDC flow to 3780 gpm (2) secure the ‘B’ LPSI Pump, then GO TO HR-2, Natural Circ.

(First part is plausible if thought that flow lowering to 4200 gpm puts the LPSI Pump in its ‘rumble region’ however lowering flow to the low end of the band is the correct action to take. Second part is plausible since Train ‘B’ power is available and CS Pumps can be used for SDC, however in MODE 4, CS Pumps should not be used for SDC. Additionally, the LMFR procedure does not direct using CS Pumps in in this condition, it directs using natural circulation.)

Answer 27

C. MVAC-1 and CTPC-2 ONLY

(NOTE - CI-1 is plausible since NCA-UV-402 is a containment Isolation Valve, but as long as NCB-UV-403 is closed, CI-1 is met. It’s plausible that CTPC-2 would not be jeopardized since one CS Pump is available and the ‘B’ LPSI Pump is available, however there is no power available to the pump due to the EDG trip.)

Question 28

• Unit 3 is cooling down for a refueling outage.
• Train ‘A’ SDC is in service using the ‘A’ LPSI Pump.
• RCS temperature is 275F and slowly lowering.
• RCS pressure is 225 psia and stable.
  Subsequently:
• The ‘A’ LPSI Pump seizes due to a loss of lube oil.
  How will the crew mitigate this event?

A. Place Train ‘B’ SDC in service using the ‘B’ LPSI Pump per 40OP-9SI01, Shutdown Cooling Initiation.
B. Place Train ‘B’ SDC in service using the ‘B’ LPSI Pump per 40EP-9EO11, Lower Mode Functional Recovery.
C. Maintain Train ‘A’ SDC in service using the ‘A’ CS Pump per 40OP-9SI01, Shutdown Cooling Initiation.
D. Maintain Train ‘A’ SDC in service using the ‘A’ CS Pump per 40EP-9EO11, Lower Mode Functional Recovery.

Answer 28

B. Place Train ‘B’ SDC in service using the ‘B’ LPSI Pump per 40EP-9EO11, Lower Mode Functional Recovery.

(NOTE - CS cannot be used for SDC in MODE 4.)

Question 29

• Unit 2 tripped from 100% power due to a loss of offsite power.
• Both EDGs failed and the CRS has just transitioned to 40EP-9EO08, Blackout.
• The ECC reports that an offsite power source should be available in the next 30 minutes.
• The RO reports the following Containment parameters:
  
  • Containment pressure is 2.8 psig and slowly rising.
  • Containment temperature is 210F and slowly rising.
    Based on these parameters, the CRS should determine that the Containment Temperature and Pressure Control safety function is not met due to Containment (1) and the CRS should (2).

A. (1) pressure ONLY (2) remain in 40EP-9EO08, Blackout, and direct the RO to perform Appendix 53, Align De-energized Buses, in anticipation of the restoration of offsite power.
B. (1) pressure ONLY (2) transition to 40EP-9EO09, Functional Recovery, and take action per MVAC-3, SBOG, to aid in restoring the CTPC safety function.
C. (1) pressure AND temperature (2) remain in 40EP-9EO08, Blackout, and direct the RO to perform Appendix 53, Align De-energized Buses, in anticipation of the restoration of offsite power.
D. (1) pressure AND temperature (2) transition to 40EP-9EO09, Functional Recovery, and take action per MVAC-3, SBOG to aid in restoring the CTPC safety function.

Answer 29

D. (1) pressure AND temperature (2) transition to 40EP-9EO09, Functional Recovery, and take action per MVAC-3, SBOG to aid in restoring the CTPC safety function.

(NOTE - First part is plausible since the SFSC for containment pressure is exceeded; however both pressure and temperature are above their SFSC limits for blackout. Second part is plausible since Appendix 53 would be directed, however transition to the FR is required due to not meeting the CPTC safety function.)

Question 30

• Unit 1 is tripped from 100% power.
  SPTAs are complete with the following conditions:
• The ‘A’ ESF Transformer, NBN-X03, has relayed on sudden pressure.
• The ‘A’ EDG tripped on low lube oil.
• RCS pressure is 1550 psia and lowering.
• The ‘B’ HPSI Pump is running with 0 psia discharge pressure.
• RCS Subcooling is 20F superheated and becoming more superheated.
• AFB-P01 has a sheared shaft.
• AFA-P01 tripped on overspeed and cannot be reset.
• SG #1 level is 35% WR and lowering.
• SG #2 level is 40% WR and lowering.
• Containment pressure is 6 psig and rising.

The CRS will enter 40EP-9EO09, Functional Recover, and direct…

A. Energizing PBA-S03 from NBN-X04 per MVAC-1, Offsite Power.
B. Performing Appendix 58, Cross-Tie DG ‘B’ to PBA-S03 per MVAC-2, DGs.
C. Depressurize got the RCS tp <220 psia to initiate LPSI injection per IC-2, SI.
D. Performing Appendix 44, feeding with Condensate Pumps per HR-2, SG with SI.

Answer 30

A. Energizing PBA-S03 from NBN-X04 per MVAC-1, Offsite Power.

(NOTE - Answer B is plausible since ‘B’ EDG is running due to the SIAS and is not loaded since PBB-S04 is still powered from off-site, however MVAC-1 is preferable to MVAC-2.)
