Upon failure of the reactor to trip from the control room, the crew should transition from AOP-1B Unit 1/EOP-0 Unit 1, Reactor Trip or Safety injection to CSP-S.1 Unit 1, Response to Power Generation / ATWS.
After completing the actions in CSP-S.1 Unit 1, the crew should transition back to EOP-0 Unit 1, Step 1 RNO.
Concurrent with the implementation of EOP-0 Unit 1, the crew should complete the remainder of AOP-1B Unit 1 Step 18 which was suspended when entering CSP-S.1Unit 1.
The crew should complete the actions of EOP-0 Unit 1 and transition to EOP-1 Unit 1, Loss Of Reactor Or Secondary Coolant and then to EOP-1.2 Unit 1, Post LOCA Cooldown and Depressurization to address the Small Break LOCA.
- 8. Safety Injection Pump failures: 1P-15A, Safety Injection pump trips upon starting and 1P-15B, Safety Injection pump fails to auto start Following immediate actions of EOP-0 Unit 1, The crew may manually start a Safety Injection Pump in accordance with OM 3.7, AOP And EOP Procedure Usage For Response To Plant Transients, otherwise pump start is addressed in EOP-0 Unit 1, Attachment A, Step A3.a.RNO .

Since a simulator malfunction during this session resulted in a loss of the ability to manually control feedwater flow to the affected steam generator, this resulted in a transition to the step 17.a RNO column. The expected actions for the crew per the procedure then became:
-Shut affected feedwater regulating bypass valve.
-Trip the reactor.
-Stabilize plant using EOPs while continuing with procedure.

PBN LOI NRC 17E, 2017 NRC Exam Scenario 3, Rev. 0 SEG SEQUENCE OF EVENTS ALL TIMES IN THIS SCENARIO ARE APPROXIMATE Event # Description
- 1. P-32A, Service Water Pump trips with reduced head capacity on P-32B and P-32D The crew may start an idle SW pump to clear the low flow alarm.
The crew should respond by implementing AOP-9A, Service Water System Malfunction and referring to Technical Specifications.
- 2. 1RE-219, SG Blowdown Monitor fails high off-scale. 1MS-2083, 1HX-1A SG Sample Isolation Control Valve fails to auto close.
The crew should reference the RMSARB CI RE219 and take actions to align equipment that did not automatically reposition.
The crew should implement AOP-3 Unit 1, Steam Generator Tube Rupture, determine a leak rate and reference Technical Specifications.
The crew should make preparations to reduce load in accordance with OP 3A Unit 1, Power Operation to Hot Standby Unit 1 or AOP-17A Unit 1, Rapid Power Reduction.
- 4. The mechanical pump seal for 1P-11A, Component Cooling Water Pump begins leaking at an increased rate that causes a lowering CCW Surge Tank level.
The crew should manually start 1P-11B, Component Cooling Water Pump, secure 1P-11A, implement AOP-9B Unit 1, Component Cooling System Malfunction and refer to Technical Specifications
- 5. Main Turbine Generator Voltage Regulator Trouble results in Main Generator Lockout and reactor trip Initially the crew should dispatch an Auxiliary Operator to investigate local alarms.
Once the unit has tripped the crew should respond by implementing EOP-0 Unit 1, Reactor Trip or Safety Injection and EOP-0.1 Unit 1, Reactor Trip Response.
- 6. Multiple stuck rods post trip The crew should borate in accordance with EOP-0.1 Unit 1, Reactor Trip Response.
- 7. 1HX-1A SG tube leak increases in size to a steam generator tube rupture After addressing the stuck rods EOP-0.1 Unit 1, plant conditions degrade necessitating a safety injection and return to EOP-0 Unit 1, Step 4 per the Foldout Page Criteria in EOP-0.1 Unit 1.
The crew will then transition from EOP-0 Unit 1 to EOP-3 Unit 1, Steam Generator Tube Rupture to isolate the ruptured generator and cooldown/depressurize the unit to minimize primary to secondary coolant leakage.
- 8. 1RC-431A and B, PZR Spray Valves fail closed.
Unavailable normal spray will require the crew to use a PORV during the depressurization phase of EOP-3 Unit 1 in order to effectively reduce RCS pressure.
STOP Terminate the scenario when the crew has stopped SI pumps and taken appropriate action(s) per step 30 of EOP-3 Unit 1,Steam Generator Tube Rupture.

2.1.3 If HiGH alarm is from an area monitor, ensure that affected areas are properly posted per RP procedures.
2.1.4 If HIGH alarm is from a process monitor with a control function:
a) Check that the control function has actuated, e.g.,
discharge valve shuts, ventilation dampers shifts, etc.
b) If control function has not actuated, initiate the control function manually. Identify the problem and correct it prior to attempting to return the channel to normal operation.
2.1.5 If the HIGH alarm is from a process monitor without a control function: identify the cause of the alarm.
2.1.6 Effluent pathways that have a monitor above its Alert alarm setpoint for at least one ten minute period should be sampled to determine Emergency Plan initiation/classification based on NUUREG 1022 reporting requirements. Ensure samples are collected at the time of the event.
