- , Scenario Summary: Scenario Event Description Shearon-Harris 2009A NRC Scenario 1 The plant is at 100% power in middle of life. The 'B' RHR Pump is out of service for breaker inspection and there is a 4 GPD tube leak on the 'B' Steam Generator.
The crew has been directed to lower power using GP-006, Normal Plant Shutdown, to <90% power in preparation for OPT-1014, Turbine Valve Test, Semi-Annual Interval Modes 1-5. The first event is the power reduction.
For this reactivity manipulation it is expected that the SRO will conduct a reactivity brief, the RO will borate per the reactivity plan and the BOP will operate the DEH Controls as necessary to lower power. The second event, a failure of REM-01 L T-3502ASA, Cnmt RCS Leak Detection Radiation Monitor, can be inserted once the power reduction has been observed to the extent necessary.
This failure will cause the output to immediately fail high and the RM-11 will go into high alarm. The automatic response to isolate Normal Containment Purge fails to occur due to a failed relay. The crew should respond to the alarms and enter AOP-005, Radiation Monitoring.
Attachment 1 of AOP-005 will direct verifying that the automatic response for this alarm has occurred (other procedure options are available and detailed in exercise guide). This will also require the SRO to evaluate Tech Spec 3.4.6.1, Leakage Detection Systems. The third event, a dropped control rod, is inserted once Normal Containment Purge has been isolated.
Control Rod D-12 will drop to the bottom of the core. The crew should diagnose the event in progress and enter AOP-001, Malfunction of Rod Control and Indication System. The RO should place Rod Control in Manual as an immediate action of AOP-001. Once the crew's response has been observed to the extent necessary and the Negative Rate Alarms at the NI Panels have been cleared then the next event can occur. (NOTE: If these alarms are not cleared then the fifth event in this scenario will cause a reactor trip.) This event will also require the SRO to evaluate Tech Spec 3.1.3.1, Moveable Control Assemblies, for the dropped control rod. The fourth event, the controlling Pressurizer Pressure Channel (PT-444) failing high, can be inserted once the Negative Rate Alarms at the NI Panels have been cleared. The crew should respond to multiple alarms and enter AOP-019, Malfunction of RCS Pressure Control. The RO should complete the immediate actions by closing the open Pressurizer PORV (PCV-444B) and gaining control of the Pressurizer Spray Valves. Depending on crew response time, a short turbine runback may occur. RCS pressure may drop below the DNB limit depending on how fast the operator responds to the failure. If so, the SRO should evaluate Tech Spec 3.2.5, DNB Parameters.
The crew should be allowed to complete AOP-019 to stabilize the plant, but the channel does not have to be removed from service to continue the scenario.
The fifth event, a loss of Instrument Bus S-III, can be inserted once plant pressure has been restored and stabilized.
The loss will occur due to a blown fuse on the 7.5kVA Inverter.
This Harris 2009A NRC Scenario 1 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 1 will require entry into AOP-024, Loss of Uninterruptible Power Supply. This procedure has immediate actions. The RO should verify Rod Control in Manual (already done due to previous AOP-001 entry) and the BOP should take manual control of all three Main FW Regulating Valves. This malfunction will also cause an auto start of the 'A' ESW pump due to a loss of PT-9101A and a loss of the running ESCWS Chiller due to loss of FT-9209A.
The instrument bus can be restored by transferring to the alternate power supply. SRO should evaluate Tech Specs 3.7.4 (Emergency Service Water), 3.7.13 (Essential Services Chilled Water System), and 3.B.1.1 (AC Sources -Operating).
Once power has been restored to Instrument Bus S-III via the alternate power supply, a Main Steam Line Break inside Containment on the 'A' SG will occur and progressively worsen over the next five minutes. The crew should enter and carry out actions of PATH-1. The crew should diagnose that there is no LOCA in progress and transition to EPP-014, Faulted Steam Generator Isolation.
The automatic Main Steam* Line Isolation signal (which should occur at 3 psig in Containment) is failed. The crew will have to manually isolate the Main Steam Isolation Valves (MSIVs). Once the crew has manually shut the MSIVs, it will be identifiable that the 'A' Steam Generator is faulted inside Containment.
The AFW Auto Isolation will not occur and the crew will have to manually isolate AFW flow to the 'A' Steam Generator.
In addition, the 'B' CSIP will fail to start automatically from the 'B' Sequencer.
The pump can be started by the operator.
The scenario ends when Safety Injection has been terminated and the crew transitions to EPP-OOB, SI Termination.

Initial Conditions:
- IC-28, MOL, 39% power * 'B' RHR Pump Out of Service for inspection
- 'B' Containment Spray Pump out of service to replace its motor
- 4 GPD tube leak on 'B' Steam Generator Turnover:
- Normal shutdown is in progress lAW with GP-006, Normal Plant Shutdown, due to elevated vibrations on Main Turbine at 100% power. Vibrations have subsided but Shutdown is to continue to perform inspection on Turbine. Currently in progress on Step 15 of G P-006 with Step 16 com pleted. Critical Task:

The crew is lowering power in accordance with GP-006, Normal Plant Shutdown, due to elevated vibrations observed on the Main Turbine at 100% power. Vibrations have subsided since power has been reduced, but shutdown is to continue so that an inspection of the Main Turbine can be performed.
Currently the 'B' RHR pump is out of service, the 'B' Containment Spray Pump is out of service, and there is a 4 GPO tube leak on 'B' Steam Generator.
The first event is for the crew to continue lowering power in accordance with their turnover.
It is expected that the SRO will conduct a reactivity brief, the RO will borate as necessary to lower power, and the BOP will operate the DEH controls as necessary to reduce turbine load. The second event, a trip of the running A-SA ESCWS Chiller, can be inserted once the downpower has been observed to the extent necessary.
The crew will respond to various alarms, diagnose the event, and enter AOP-026, Loss of Essential Chill Water System. This will direct starting the 'B' Train ESCWS Chiller. The SRO should evaluate Tech Spec 3.7.13, Essential Services Chilled Water System. Note that the 'A' Chiller will be inoperable for the remainder of the scenario and this will impact plant response during the Major Event in that this failure will prevent Load Block 9 from energizing.
The third event, a failure of the Letdown Temperature Transmitter, TT-144, can be inserted once the 'B' ESCWS Chiller has been started and ventilation properly aligned. The transmitter fails low which causes the system to attempt to increase temperature by reducing Component Cooling Water flow. As cooling flow reduces, actual temperature will increase.
The automatic divert to protect the demineralizers fails to operate. Operators should take action to restore temperature and divert letdown around the demins. From the initiation of the trigger it takes -2.5 minutes to cause an alarm. The-fourth event is the 'A' Steam Generator Controlling Level Transmitter, LT-476, failing high and can be inserted once the crew has control of letdown temperature.
This will require operator action to take manual control of 'A' Main Feedwater Regulating Valve and stabilize level. The SRO should evaluate Tech Specs 3.3.1, Reactor Trip Instrumentation, and 3.3.2, ESF Instrumentation.
The fifth event, a failure of the 'C' RCP #1 Seal, can be inserted once 'A' Steam Generator Level has stabilized and is under control of the crew. The crew should enter AOP-018, Reactor Coolant Pump Abnormal Conditions, and evaluate the seal malfunction.
The crew should identify the 'C' RCP #1 seal as failed. Since power is less than 49%, they should stop the 'C' RCP and shut 1 CS-437, 'C' RCP #1 Seal Water Return valve, between three and five minutes after securing the RCP. Once the RCP is stopped and its seal water return valve is shut, then the major event will be initiated.
The SRO should evaluate Tech Spec 3.4.1.1, Reactor Coolant Loops and Coolant Circulation.
The major event is a SBLOCA (100% severity) from the 'A' Loop. The crew should carry out immediate actions of PATH-1. The earlier failure of A-SA ESCWS Chiller will prevent the 'A' Sequencer from reaching Load Block 9. The BOP should manually actuate the MAN PERM switch to enable manual loading on the A-SA bus (due to the earlier trip of the A-SA ESCWS Chiller).
Shortly after entering PATH-1, the crew should recognize that the Foldout Criteria for Harris 2009A NRC Scenario 2 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 2 securing all RCPs has been met and carry out that action. Pressure in containment will continue to rise due to the LOCA and a Containment Spray Actuation will be required.
The 'A' Cnmt Spray Pump will start automatically, but 1CS-50, 'A' Cnmt Spray Pump Discharge valve, and 1CS-12, Cnmt Spray Additive valve, will fail to open automatically.
The crew should identify this failure and manually open both valves. Since '8' Cnmt Spray Pump is under clearance, there will be no spray flow to containment until the 'A' Cnmt Spray Pump Discharge valve is manually opened. The 'A' RHR Pump will start automatically from the sequencer and then immediately trip on overcurrent.
The RO should identify this failure but the pump cannot be manually started. The loss of RHR will result in the crew exiting PATH-1 and going to EPP-012, Loss of Emergency Coolant Recirculation, to address the loss of RHR capability.
The '8' RHR Pump is under clearance for routine maintenance and can be made available by the booth operator once the crew has entered EPP-012 (or if FRP-P.1 entry was required prior to EPP-012 entry) and the request has been made to restore '8' RHR Pump to service.
Due to the rapid cooldown an Orange conditions will occur for Core Cooling. This will require the crew to implement FRP-P.1. The crew will progress through FRP-P.1 until they are required to perform a soak for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Terminate the scenario once the crew determines a soak is required and start to carry out actions of other procedures that do NOT cause an RCS cooldown OR increase pressure.

A plant startup is in progress lAW GP-005, Power Operation.
The first priority will be to raise power from 4% to 7% -9% so that they can transfer control from Feedwater Regulating Valve Bypass FCVs to the Main Feedwater Regulating Valves. Once the first Main Feedwater Regulating Valve is placed in service then the scenario will proceed to the next event. They will continue to work at placing FRV's in auto during the scenario.
Once the increase in power has been observed to the extent necessary and 'A' Main FRV is in auto, then event #2 can be inserted.
This event is Pressurizer Pressure Channell, PT-455, failing high. This will cause a MCB annunciator to alarm. The RO will report that PT -455 pressure indication is high and the crew will implement OWP-RP-02 to remove the failed channel from service. The SRO should evaluate Tech Specs 3.3.1 (Reactor Trip Instrumentation), 3.3.2 (ESF Instrumentation), and 3.3.3.5.a (Remote Shutdown System), for the failed channel and request assistance from the WCC. Event #3, Pressurizer Spray Valve PCV-444C failing open, can be initiated once Tech Specs for PT-455 have been evaluated.
Pressurizer pressure will decease and all pressurizer heaters will energize.
Annunciators for pressurizer low pressure will alarm. The crew should respond by entering AOP-019, Malfunction of RCS Pressure Control, and place the malfunctioning spray valve in manual per the immediate actions. RCS pressure may drop below the DNB limit depending on how fast the operator responds to the failure. If so, the SRO should evaluate Tech Spec 3.2.5, DNB Parameters.
Event #4 is initiated once RCS pressure has recovered.
It is the ContrOlling Pressurizer Level Instrument, L T -459, failing high. The crew should respond in accordance with alarm response procedure APP-ALB-009. The crew should take Charging FCV-122 to Manual and maintain pressurizer level within the control band and shift level control to an alternate channel. The SRO should evaluate Tech Spec 3.3.3.5.a (Remote Shutdown System), for the failed channel and request assistance from the WCC. Event #5 is the Controlling Steam Generator Level Channel on SG 'A', LT-476, failing low. The BOP should respond to multiple 'A' Steam Generator alarms on ALB-014 and take manual control of the 'A' FRV in accordance with the alarm response procedures and OMM-001 , Conduct of Operations.
The SRO should evaluate Tech Specs 3.3.1 (Reactor Trip Instrumentation), 3.3.2 (ESF Instrumentation), and 3.3.3.6 (ACCident Monitoring Instrumentation).
The OWP is not required to be implemented in order to continue with the scenario.
Event #6 is High Vibration on the Main Turbine. Vibrations will continue to rise over two minutes to the point that a Turbine Trip is required.
Since power is <P-7 the crew trip the turbine only and continue on in AOP-006, Turbine Generator Trouble. Crew should continue on in the procedure to the point that they isolate and break vacuum. Once this action has been performed continue on with Event 7. Event #7 is the dropping of one control rod. The RO should report the drop of a single control rod. The crew will enter AOP-001 and perform the immediate actions. (NOTE: a component failure for Event # 7 is NOT credited for the RO during this malfunction due to the rod control system being placed in Manual prior to the failure occurring.)
Event #8 is the dropping of the second control rod. Event 8 will occur 1.5 minutes after the drop of the first control rod. The RO should report the two dropped control rods. The crew will enter AOP-001 and the first immediate action will direct a Reactor Trip. Harris 2009A NRC Scenario 4 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 4 Event #9 The crew should recognize that the reactor has failed to trip and enter FRP-S.1, Response to Nuclear Power Generation/ATWS.
The Reactor Trip breakers will be opened locally three minutes after a field operator has been dispatched to perform those actions. Once the crew has initiated the emergency boration in FRP-S.1, they should exit FRP-S.1 and return to PATH-1. Events # 10 and 11 Once the crew has entered PATH-1, the Lead Examiner can cue the loss of off-site power. The 'A' EDG will fail to start and the 'B' EDG Output Breaker will fail to shut automatically.
The crew should enter EPP-001, Loss of AC Power to 1 A-SA and 1 B-SB Buses. Manual operation of the 'B' EDG Output breaker is available and the crew should restore power to the 'B' Safety Bus using the 'B' EDG. Terminate the scenario when the crew transitions out of EPP-001. (Note there is no exit available from EPP-001 without restoring power to at least one of the Safety Buses.) Harris 2009A NRC Scenario 4 FINAL Appendix D Scenario Outline Form ES-D-1 Facility:

The 'B' RHR Pump is out of service for breaker inspection and there is a 4 GPD tube leak on the 'B' Steam Generator.
The crew has been directed to lower power using GP-006, Normal Plant Shutdown, to <90% power in preparation for OPT-1014, Turbine Valve Test, Semi-Annual Interval Modes 1-5. The first event is the power reduction.
For this reactivity manipulation it is expected that the SRO will conduct a reactivity brief, the RO will borate per the reactivity plan and the BOP will operate the DEH Controls as necessary to lower power. The second event, a failure of REM-01 L T -3502ASA, Cnmt RCS Leak Detection Radiation Monitor, can be inserted once the power reduction has been observed to the extent necessary.
This failure will cause the output to immediately fail high and the RM-11 will go into high alarm.
The automatic response to isolate Normal Containment Purge fails to occur due to a failed relay. The crew should respond to the alarms and enter AOP-005, Radiation Monitoring.
Attachment 1 of AOP-005 will direct verifying that the automatic response for this alarm has occurred (other procedure options are available and detailed in exercise guide). This will also require the SRO to evaluate Tech Spec 3.4.6.1, Leakage Detection Systems. The third event, a dropped control rod, is inserted once Normal Containment Purge has been isolated.
Control Rod D-12 will drop to the bottom of the core. The crew should diagnose the event in progress and enter AOP-001, Malfunction of Rod Control and Indication System. The RO should place Rod Control in Manual as an immediate action of AOP-001. Once the crew's response has been observed to the extent necessary and the Negative Rate Alarms at the NI Panels have been cleared then the next event can occur. (NOTE: If these alarms are not cleared then the fifth event in this scenario will cause a reactor trip.) This event will also require the SRO to evaluate Tech Spec 3.1.3.1, Moveable Control Assemblies, for the dropped control rod. The fourth event, the controlling Pressurizer Pressure Channel (PT-444) failing high, can be inserted once the Negative Rate Alarms at the NI Panels have been cleared. The crew should respond to multiple alarms and enter AOP-019, Malfunction of RCS Pressure Control. The RO should complete the immediate actions by closing the open Pressurizer PORV (PCV-444B) and gaining control of the Pressurizer Spray Valves. Depending on crew response time, a short turbine runback may occur. RCS pressure may drop below the DNB limit depending on how fast the operator responds to the failure. If so, the SRO should evaluate Tech Spec 3.2.5, DNB Parameters.
The crew should be allowed to complete AOP-019 to stabilize the plant, but the channel does not have to be removed from service to continue the scenario.
The fifth event, a loss of Instrument Bus S-III, can be inserted once plant pressure has been restored and stabilized.
The loss will occur due to a blown fuse on the 7.5kVA Inverter.
This Harris 2009A NRC Scenario 1 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 1 will require entry into AOP-024, Loss of Uninterruptible Power Supply. This procedure has immediate actions. The RO should verify Rod Control in Manual (already done due to previous AOP-001 entry) and the BOP should take manual control of all three Main FW Regulating Valves. This malfunction will also cause an auto start of the "A' ESW pump due to a loss of PT-9101A and a loss of the running ESCWS Chiller due to loss of FT-9209A.
The instrument bus can be restored by transferring to the alternate power supply. SRO should evaluate Tech Specs 3.7.4 (Emergency Service Water), 3.7.13 (Essential Services Chilled Water System), and 3.8.1.1 (AC Sources -Operating).
Once power has been restored to Instrument Bus S-III via the alternate power supply, a Main Steam Line Break inside Containment on the "A' SG will occur and progressively worsen over the next five minutes. The crew should enter and carry out actions of PATH-1. The crew should diagnose that there is no LOCA in progress and transition to EPP-014, Faulted Steam Generator Isolation.
The automatic Main Steam Line Isolation signal (which should occur at 3 psig in Containment) is failed. The crew will have to manually isolate the Main Steam Isolation Valves (MSIVs). Once the crew has manually shut the MSIVs, it will be identifiable that the "A' Steam Generator is faulted inside Containment.
The AFW Auto Isolation will not occur and the crew will have to manually isolate AFW flow to the "A' Steam Generator.
In addition, the "B' CSIP will fail to start automatically from the "B' Sequencer.
The pump can be started by the operator.
The scenario ends when Safety Injection has been terminated and the crew transitions to EPP-008, SI Termination.

The crew has been directed to lower power using GP-006, Normal Plant Shutdown, to <90% power in preparation for Turbine Valve Testing. The crew may elect to manually crack open a PRZ Spray Valve to establish PRZ Surge line flow and thereby maintain PRZlRCS boron concentrations within limits. When PRZ backup heaters are energized in manual, PK-444A1, PRZ Master Pressure Controller (a PI controller) will integrate up to a greater than normal output, opening PRZ Spray Valves to return and maintain RCS pressure at setpoint.
The result is as follows:
- PORV PCV-444B will open at a lower than expected pressure.
- ALB-009-3-2, PRESSURIZER HIGH PRESS DEVIATION CONTROL, will activate at a lower than expected pressure.

The crew is lowering power in accordance with GP-006, Normal Plant Shutdown, due to elevated vibrations observed on the Main Turbine at 100% power. Vibrations have subsided since power has been reduced, but shutdown is to continue so that an inspection of the Main Turbine can be performed.
Currently the 'B' RHR pump is out of service, the 'B' Containment Spray Pump is out of service, and there is a 4 GPO tube leak on 'B' Steam Generator.
The first event is for the crew to continue lowering power in accordance with their turnover.
It is expected that the SRO will conduct a reactivity brief, the RO will borate as necessary to lower power, and the BOP will operate the DEH controls as necessary to reduce turbine load. The second event, a trip of the running A-SA ESCWS Chiller, can be inserted once the down power has been observed to the extent necessary.
The crew will respond to various alarms, diagnose the event, and enter AOP-026, Loss of Essential Chill Water System. This will direct starting the 'B' Train ESCWS Chiller. The SRO should evaluate Tech Spec 3.7.13, Essential Services Chilled Water System. Note that the 'A' Chiller will be inoperable for the remainder of the scenario and this will impact plant response during the Major Event in that this failure will prevent Load Block 9 from energizing.
The third event, a failure of the Letdown Temperature Transmitter, TT-144, can be inserted once the 'B' ESCWS Chiller has been started and ventilation properly aligned. The transmitter fails low which causes the system to attempt to increase temperature by reducing Component Cooling Water flow. As cooling flow reduces, actual temperature will increase.
The automatic divert to protect the demineralizers fails to operate. Operators should take action to restore temperature and divert letdown around the demins. From the initiation of the trigger it takes -2.5 minutes to cause an alarm. The fourth event is the 'A' Steam Generator Controlling Level Transmitter, LT-476, failing high and can be inserted once the crew has control of letdown temperature.
This will require operator action to take manual control of 'A' Main Feedwater Regulating Valve and stabilize level. The SRO should evaluate Tech Specs 3.3.1, Reactor Trip Instrumentation, and 3.3.2, ESF Instrumentation.
The fifth event, a failure of the 'C' RCP #1 Seal, can be inserted once 'A' Steam Generator Level has stabilized and is under control of the crew. The crew should enter AOP-018, Reactor Coolant Pump Abnormal Conditions, and evaluate the seal malfunction.
The crew should identify the 'C' RCP #1 seal as failed. Since power is less than 49%, they should stop the 'C' RCP and shut 1 CS-437, 'C' RCP #1 Seal Water Return valve, between three and five minutes after securing the RCP. Once the RCP is stopped and its seal water return valve is shut, then the major event will be initiated.
The SRO should evaluate Tech Spec 3.4.1.1, Reactor Coolant Loops and Coolant Circulation.
The major event is a SBLOCA (100% severity) from the 'A' Loop. The crew should carry out immediate actions of PATH-1. The earlier failure of A-SA ESCWS Chiller will prevent the 'A' Sequencer from reaching Load Block 9. The BOP should manually actuate the MAN PERM switch to enable manual loading on the A-SA bus (due to the earlier trip of the A-SA ESCWS Chiller).
Shortly after entering PATH-1, the crew should recognize that the Foldout Criteria for Harris 2009A NRC Scenario 2 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 2 securing all RCPs has been met and carry out that action. Pressure in containment will continue to rise due to the LOCA and a Containment Spray Actuation will be required.
The 'A' Cnmt Spray Pump will start automatically, but 1 CS-50, 'A' Cnmt Spray Pump Discharge valve, and 1CS-12, Cnmt Spray Additive valve, will fail to open automatically.
The crew should identify this failure and manually open both valves. Since '8' Cnmt Spray Pump is under clearance, there will be no spray flow to containment until the 'A' Cnmt Spray Pump Discharge valve is manually opened. The 'A' RHR Pump will start automatically from the sequencer and then immediately trip on overcurrent.
The RO should identify this failure but the pump cannot be manually started. The loss of RHR will result in the crew exiting PATH-1 and going to EPP-012, Loss of Emergency Coolant Recirculation, to address the loss of RHR capability.
The '8' RHR Pump is under clearance for routine maintenance and can be made available by the booth operator once the crew has entered EPP-012 (or if FRP-P.1 entry was required prior to EPP-012 entry) and the request has been made to restore '8' RHR Pump to service. Due to the rapid cooldown an Orange conditions will occur for Core Cooling. This will require the crew to implement FRP-P.1. The crew will progress through FRP-P.1 until they are required to perform a soak for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Terminate the scenario once the crew determines a soak is required and start to carry out actions of other procedures that do NOT cause an RCS cooldown OR increase pressure.

A plant startup is in progress lAW GP-005, Power Operation.
The first priority will be to raise power from 4% to 7% -9% so that they can transfer control from Feedwater Regulating Valve Bypass FCVs to the Main Feedwater Regulating Valves. Once the first Main Feedwater Regulating Valve is placed in service then the scenario will proceed to the next event. They will continue to work at placing FRV's in auto during the scenario.
Once the increase in power has been observed to the extent necessary and 'A' Main FRV is in auto, then event #2 can be inserted.
This event is Pressurizer Pressure Channell, PT-455, failing high. This will cause a MCB annunciator to alarm. The RO will report that PT-455 pressure indication is high and the crew will implement OWP-RP-02 to remove the failed channel from service. The SRO should evaluate Tech Specs 3.3.1 (Reactor Trip Instrumentation), 3.3.2 (ESF Instrumentation), and 3.3.3.5.a (Remote Shutdown System), for the failed channel and request assistance from the WCC. Event #3, Pressurizer Spray Valve PCV-444C failing open, can be initiated once Tech Specs for PT-455 have been evaluated.
Pressurizer pressure will decease and all pressurizer heaters will energize.
Annunciators for pressurizer low pressure will alarm. The crew should respond by entering AOP-019, Malfunction of RCS Pressure Control, and place the malfunctioning spray valve in manual per the immediate actions. RCS pressure may drop below the DNB limit depending on how fast the operator responds to the failure. If so, the SRO should evaluate Tech Spec 3.2.5, DNB Parameters.
Event #4 is initiated once RCS pressure has recovered.
It is the Controlling Pressurizer Level Instrument, L T -459, failing high. The crew should respond in accordance with alarm response procedure APP-ALB-009. The crew should take Charging FCV-122 to Manual and maintain pressurizer level within the control band and shift level control to an alternate channel. The SRO should evaluate Tech Spec 3.3.3.5.a (Remote Shutdown System), for the failed channel and request assistance from the WCC. Event #5 is the Controlling Steam Generator Level Channel on SG 'A', LT-476, failing low. The BOP should respond to multiple 'A' Steam Generator alarms on ALB-014 and take manual control of the 'A' FRV in accordance with the alarm response procedures and OMM-001 , Conduct of Operations.
The SRO should evaluate Tech Specs 3.3.1 (Reactor Trip Instrumentation), 3.3.2 (ESF Instrumentation), and 3.3.3.6 (Accident Monitoring Instrumentation).
The OWP is not required to be implemented in order to continue with the scenario.
Event #6 is High Vibration on the Main Turbine. Vibrations will continue to rise over two minutes to the point that a Turbine Trip is required.
Since power is <P-7 the crew trip the turbine only and continue on in AOP-006, Turbine Generator Trouble. Crew should continue on in the procedure to the point that they isolate and break vacuum. Once this action has been performed continue on with Event 7. Event #7 is the dropping of one control rod. The RO should report the drop of a single control rod. The crew will enter AOP-001 and perform the immediate actions. (NOTE: a component failure for Event # 7 is NOT credited for the RO during this malfunction due to the rod control system being placed in Manual prior to the failure occurring.)
Event #8 is the dropping of the second control rod. Event 8 will occur 1.5 minutes after the drop of the first control rod. The RO should report the two dropped control rods. The crew will enter AOP-001 and the first immediate action will direct a Reactor Trip. Harris 2009A NRC Scenario 4 FINAL Scenario Event Description Shearon-Harris 2009A NRC Scenario 4 Event #9 The crew should recognize that the reactor has failed to trip and enter FRP-S.1, Response to Nuclear Power Generation/ATWS.
The Reactor Trip breakers will be opened locally three minutes after a field operator has been dispatched to perform those actions. Once the crew has initiated the emergency boration in FRP-S.1, they should exit FRP-S.1 and return to PATH-1. Events # 10 and 11 Once the crew has entered PATH-1, the Lead Examiner can cue the loss of off-site power. The 'A' EDG will fail to start and the 'B' EDG Output Breaker will fail to shut automatically.
The crew should enter EPP-001, Loss of AC Power to 1 A-SA and 1 B-SB Buses. Manual operation of the 'B' EDG Output breaker is available and the crew should restore power to the 'B' Safety Bus using the 'B' EDG. Terminate the scenario when the crew transitions out of EPP-001. (Note there is no exit available from EPP-001 without restoring power to at least one of the Safety Buses.)
