- LOCA into Containment.

- Unisolable Steam Line Break into Containment.

Before EOP Entry:

1. 1PT-431, Blue Channel Pressurizer Pressure Transmitter, fails LOW.
2. Failure of Bus 15 Load Sequencer.
3. 11 Main Feed Pump Lockout.

After EOP Entry:

1. Reactor Fails to automatically trip.
2. Failure of CC Pumps to automatically start.

Abnormal Events:

1. Controlling Channel Pressurizer Pressure Instrument Failure.
2. Bus 15 Load Sequencer Out of Service.
3. Loss of Main Feedwater.
4. Loss of Component Cooling.

Major Transients:

1. Large Break LOCA.

Critical Tasks:

1. Manually trip the reactor from the Control Room before both Steam Generator Wide Range Levels lower below 9%.
2. Manually start at least one CC Pump before the end of the scenario.

Page 3 of 17 2016 ILT NRC SIMULATOR EVALUATION #3 CRITICAL TASK SHEET Manually trip the reactor from the Control Room before both Steam Generator Critical Task: Wide Range Levels lower below 9%.

If the main turbine trips and the reactor fails to automatically trip, then the steam dumps and/or SG PORVs will draw steam from the Steam Generators.

This steam will not return to the main condenser and hotwell. This results in rapidly lowering hotwell level, eventual trip of the Main Feedwater Pumps, and Safety loss of feedwater to the Steam Generators.

Significance: During a loss of feedwater to the Steam Generators, the turbine, steam dumps, or SG PORVs are drawing steam from the Steam Generators. This causes Steam Generator levels to rapidly lower. Once the SGs are dry, the heat removal capability of the RCS is lost. This leads to RCS pressure increase and RCS boundary failure.

o Loss of normal feedwater to the Steam Generators.

o Main Turbine Trip.

  • Determine RCS Cooldown and Depressurization is NOT required.
  • Prepare for Switchover to Recirculation Phase:

o Stop Spent Fuel Pool Vent System.

o Notify Outplant to perform Attachment K.

1ES-1.2, TRANSFER TO RECIRCULATION

  • Prepare for switchover to recirculation phase.
  • Check both trains of safeguards pumps available for recirculation.
  • Stop one train of safeguards pumps.
  • Close RWST to RHR Isolation Valve for idle RHR pump.

o MV-32084 if 11 RHR Pump is idle.

o MV-32085 if 12 RHR Pump is idle.

  • Close SI Test Line to RWST Valves, MV-32202 AND MV-32203.
  • Verify RHR to Reactor Vessel Injection Valve Alignment by verifying open MV-32064 AND MV-32065.

SEQ SEQUENCE OF EVENTS / INSTRUCTOR NOTES CREW EXPECTED STUDENT RESPONSES POS

  • Align CC to RHR HX for idle RHR train by verifying OPEN:

o MV-32093 if 11 RHR Pump is idle.

o MV-32094 if 12 RHR Pump is idle.

  • Check Containment Level greater than 2 feet.
  • Check if RHR suction can be aligned to Containment Sump by verifying power to:

o MV-32077 if 11 RHR Pump is idle.

o MV-32078 if 12 RHR Pump is idle.

  • Verify RWST to RHR isolation valve for idle RHR pump is CLOSED.

o MV-32084 if 11 RHR Pump is idle.

o MV-32085 if 12 RHR Pump is idle.

  • Open Sump B to RHR isolation valves for idle RHR pump.

o MV-32077 if 11 RHR Pump is idle.

o MV-32078 if 12 RHR Pump is idle.

  • Check if second CS pump can be stopped.
  • Verify Sump B to RHR isolation valves for idle RHR pump are full open.

o MV-32077 if 11 RHR Pump is idle.

o MV-32078 if 12 RHR Pump is idle.

  • Start idle RHR pump.
  • Determine RCS pressure is less than 250 psig.
  • Determine RHR flow is greater than 950 gpm.

END When one train of ECCS has been placed in the recirculation mode, or at the discretion of the Lead Evaluator, then place the simulator in FREEZE.
