Appendix D Scenario Outline Form ES-D-1 Scenario Summary: | |||
With the unit at 83% power, the BOP operator will rotate Bus Duct Cooling Fans JAW 3-01-47 section 6.11 .1 [2]. Upon completion the ATC will commence power increase with flow. | |||
When the NRC is satisfied with the reactivity manipulation, CRD Pump 3A will trip. ATC will perform 3-AOI-85-3 actions to start the Standby CR1) Pump. | |||
Once the Standby CRD Pump is started and CRD parameters are restored, the Hydrogen Water Injection system will malfunction resulting in high hydrogen concentration in Off Gas. The crew will respond JAW with ARPs and 3-AOI-66-1 and shutdown the Hydrogen Water Chemistry System. The SRO will address TRM 3.7.2 and Enter Condition A. | |||
After shutdown of the HWC System, high vibration alarms on Reactor Recirculation Pump 3A will have the crew respond JAW the ARPs. The ARPs will direct the operators to adjust RR Pump 3A speed in an attempt to lower vibrations on RR Pump 3A. Once speed is adjusted, high vibration alarm will clear and vibrations will lower. | |||
After the RR Pump 3A vibrations is addressed, HPCI will inadvertently initiate. The crew will verify the initiation is inadvertent and trip and lockout HPCI. The SRO will address Technical Specification 3.5.1 and Enter Condition C. | |||
Shortly after the HPCI initiation a steam leak will develop in the HPCI Room, HPCI will fail to automatically and manually isolate. When attempting to manually isolate HPCI steam valve 73-2 the 3A RMOV Board will be lost due to an electrical fault. | |||
The crew will enter EOI-3 and scram the Reactor. All rods will insert on the scram and level and pressure will be controlled JAW EOI-1. The crew should lower reactor pressure. As the second MAX safe temperature is approached, the crew should anticipate Emergency Depressurization and when the second MAX safe temperature is reached the crew will Emergency Depressurize. | |||
During ED one ADS valve will fail and the operator will open an additional SRV. After ED, the startup level controller will fail. The crew will control level with Core Spray Loop 2 and place R}JR Loop 2 in Suppression Pool Cooling. | |||
The Emergency classification is 3.1-S Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner. | |||
All Control Rods are inserted. | |||
Emergency Depressurization complete. | |||
Reactor Level is restored and maintained. | |||

Appendix D Scenario Outline Form ES-D-1 Scenario Summary: | |||
BOP will perform Stroke Time Test on 3-FCV-43.13 and 3-FCV-43-14 with 3-FSV-43-14 failing the stroke time test. SRO will determine Technical Specification 3.6.1.3 Condition A required. | |||
Then, the ATC will raise power with Reactor Recirculation flow to 95%. | |||
Once evaluators satisfied with Reactivity Manipulations, the VFD Cooling Water Pump for the B Reactor Recirc VFD will trip and the standby pump will fail to start. The ATC will start the standby VFD Cooling Water Pump to restore cooling water preventing a VFD and Reactor Recirc Pump trip. | |||
Steam Packing Exhauster will trip and the STBY Exhauster will Start but the discharge damper will fail to open. The BOP will open the Steam Packing Exhauster discharge damper and restore Steam Packing Exhauster operation JAW with ARPs. | |||
A leak will develop on RHR Loop 1 common minimum flow line, field reports will indicate the leak can be isolated by closing RHR A and C Pump suction valves. Once suction valves are closed SRO will determine Technical Specification 3.5.1 Condition A is required, TS 3.6.2.3 Condition B, 3.6.2.4 Condition B, and 3.6.2.5 Condition B all 7 Days. | |||
After RHR Loop 1 is isolated an RBCCW Pump will trip and the sectionalizing valve will fail to close automatically. Operators will take actions JAW 3-AOI-70-1 and trip RWCU Pumps and close the sectionalizing valve for RBCCW. | |||
A LOCA will occur, RPS will fail to de-energize, the crew will scram the Reactor by arming and depressing ARI, and enter EOI-1 and EOI-2. All rods will insert on ART, level control will be on feedwater and pressure control will be on SRVs(only three SRVs are available. The bypass valves fail closed during the scram. The LOCA will cause increasing DW Pressure and Temperature; the crew will take action JAW EOI-2. When the crew attempts to spray the Drywell, the Drywell Spray valves will fail to open. Unable to spray the drywell the crew will need to establish limits for DW pressure and temperature for anticipating ED and ED. | |||
The Emergency classification is 2.1-A Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner. | |||
All Control Rods are inserted. | |||
Emergency Depressurization is complete Reactor Level is restored and maintained. | |||

The Plant is operating at 86% Reactor Power. | |||
The BOP Operator will perform Automatic Start Test of RFPT 3A EBOP 3A3 Oil Pump, 3-01-3 Section 8.13 The ATC will adjust the Control Rod Pattern JAW RCP. When the 4 th control rod is withdrawn, it will continue to move 3 notches beyond its intended positions. The ATC will completely insert the Control Rod JAW 3-AOI-85-6 or 3-AOI-85-7. Accumulator must be declared mop if charging water is isolated. The SRO may declare the Control Rod Inoperable Technical Specification 3.1.3 condition C. | |||
A RCIC Steam Line Break will result in high Room temperature with a failure of RCIC to Isolate. | |||
The BOP will isolate RCIC. The SRO will determine RCIC Isolation Valves inoperable and RCIC System inoperable. With HPCI already Inoperable, plant shutdown is required. Technical Specification 3.5.3 Condition B and 3.6.1.3 Condition A. | |||
A tube leak on High Pressure Feedwater Heater B2 results in isolation of Extraction Steam to the heater. The crew will respond in accordance with 3 -AOI 1 A or 1 C. The ATC will lower reactor power by 5%. The Operators refer to 3-AOI 1 A or 1 C and determine that all automatic actions failed to occur and the Operators isolate the Heater B2. | |||
A Feedwater line break will occur in the Turbine Building. The Loss of Feedwater Flow 3-AOI-3-1 should be entered and a manual Scram inserted. EOI- 1 will be entered on Reactor Level. | |||
EOI-2 will be entered on High Drywell Pressure / Temperature. Actions of EOI-2 will be directed. | |||

The Plant is operating at 4% Reactor Power. | |||
The BOP Operator will Aligning Charcoal Filters for Parallel Flow JAW 3-01-66 section 5.11. | |||
The ATC will withdraw control rods in order to raise power to 8% for a mode change from 2 to 1. | |||
Once the NRC is satisfied with the reactivity manipulation, Reactor Recirculation Pump B will trip. | |||
The SRO will direct entry to 3-A0I-68-1A, the ATC will close RR Pump B discharge valve. | |||
The SRO will evaluate Technical Specification 3.4.1 Condition A is required. | |||
Core Spray Pump 3A inadvertently initiates with loss of minimum flow protection. BOP Operator verifies initiation is inadvertent and with SRO concurrence stop Core Spray Pump 3A JAW with ARPs. The SRO will evaluate Technical Specification 3.5.1 Condition A is required. | |||
The Steam Seal regulator will fail, the BOP Operator will take action JAW with the ARPs and restore steam seal pressure with the bypass valve. | |||
The operating feedwater pump controller will fail, level will slowly rise until the ATC or Crew notices the Reactor Level change. The controller will fail to respond until the ATC takes manual control with handswitch. The Operator will be able to maintain Reactor Level control in manual. | |||
SRO should direct entry into 3-AOI-3-l. | |||
An unisolable Torus leak will commence. Suppression Pool level will start to lower and continue to lower. The SRO will enter EOI-3 on flood alarms and eventually EOI-2 on Suppression Pool Level. | |||
The SRO will determine that Suppression Pool level cannot be maintained above 11.5 feet and enter E0I-l to scram the reactor and then to Emergency Depressurize. | |||
An ATWS will exist on the scram, the crew will work through EOI-1 and C-S to insert control rods, maintain reactor level and pressure. The SRO will transition to C-2 to Emergency Depressurize. | |||
Attempts to add water to the suppression pool will be unsuccessful with the failure of 3-FCV-73-30 and 3-FCV-74-57. | |||
The Emergency Classification is 1.2-S Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner: | |||
All but six Control Rods are inserted Emergency Depressurization complete Reactor Level is restored and maintained | |||

Appendix D Scenario Outline Form ES-D-1 Scenario Summary: | |||
BOP will remove LPRM 8-49B from bypass JAW 2-OI-92B section 6.4. | |||
ATC will raise Reactor Power with control rods as directed by the Reactivity Control Plan. | |||
During power ascension Control Rod 14-3 5 will experience an RPIS position failure. The crew will respond JAW ARPs and 2-AOI-85-4. The ATC will insert Control Rod 14-3 5 one notch to establish position indication. After Control Rod 14-3 5 is inserted it will begin to drift in, the ATC will respond JAW 2-AOI-85-5 and insert the control rod to position 00. | |||
EECW D3 Pump will trip and the standby EECW Pump B3 will fail to auto start, the BOP will respond JAW ARPs and start EECW Pump B3 to EECW flow to the north header. | |||
The SRO will evaluate Technical Specification 3.7.2 and Condition A is entered. | |||
Outboard MSIV D will drift closed, the crew will respond JAW 2-AOI-1-3. The ATC will lower Reactor Power to less than 66% and the BOP will fully close Outboard MSIV D. The SRO will evaluate Technical Specification 3.6.1.3 and Condition A is entered. | |||
Feedwater Flow Transmitters will fail the crew will respond JAW ARPs and 2-AOI-3 -1, the ATC will report that Feedwater Level Control transferred to single element and will transfer to single element. Reactor Level will stabilize after the initial transient. | |||
Vacuum will begin to degrade and the crew will respond JAW 2-AOI-47-3, the crew will insert a manual Reactor scram prior to the Main Turbine trip. An ATWS will exist and the crew will enter EOI- 1 and C-5. | |||
After the scram and airline break will occur in the drywell causing MSJV closure and transition to SRVs for pressure control and RCIC for level control. Until the crew performs Appendix 8G, SRV operation will degrade due to the loss of air. | |||
CRD Pump 2A will trip and the ATC will start CRD Pump lB in order to insert control rods. | |||
The crew will maintain directed level and pressure bands, insert all control rods and enter EOI-2 and place RHR in Suppression Pool Cooling. | |||

Appendix 0 Scenario Outline Form ES-D-1 Critical Tasks - Two CT#1-With reactor at power and with a primary system discharging into the secondary containment, manually scram the reactor before any area exceeds the maximum safe operating level.
- 1. Safety Significance:
Scram reduces to decay heat energy that the RPV may be discharging into the secondary containment.
- 2. Cues:
Procedural compliance.
Secondary containment area temperature, level, and radiation indication.
Field reports.
- 3. Measured by:
Observation With a primary system discharging into secondary containment, a reactor scram is initiated before a maximum safe condition is reached.
OR Observation With a primary system discharging into secondary containment, US transitions to EOP-l and RO initiates scram upon report that a maximum safe condition has been reached.
- 4. Feedback:
Control rod positions.
Reactor power decrease.
CT#2-With a primary system discharging into the secondary containment, when two or more areas are greater than their maximum safe operating values for the same parameter, RO initiates Emergency Depressurization as directed by US.
- 1. Safety Significance:
Places the primary system in the lowest possible energy state, rejects heat to the suppression pool in preference to outside the containment, and reduces driving head and flow of system discharging into the secondary containment.
- 2. Cues:
Procedural compliance.
Secondary containment area temperatures, level, and radiation indication.
Field reports.
- 3. Measured by:
Observation US transitions to C-2 and RO opens at least 6 SRVs when two or more areas are greater than their maximum safe operating values for the same parameter.
- 4. Feedback:
RPV pressure trend.
SRV status indications.
Appendix D Scenario Outline Form ES-D-1 Scenario Summary:
With the unit at 83% power, the BOP operator will rotate Bus Duct Cooling Fans JAW 3-01-47 section 6.11 .1 [2]. Upon completion the ATC will commence power increase with flow.
When the NRC is satisfied with the reactivity manipulation, CRD Pump 3A will trip. ATC will perform 3-AOI-85-3 actions to start the Standby CR1) Pump.
Once the Standby CRD Pump is started and CRD parameters are restored, the Hydrogen Water Injection system will malfunction resulting in high hydrogen concentration in Off Gas. The crew will respond JAW with ARPs and 3-AOI-66-1 and shutdown the Hydrogen Water Chemistry System. The SRO will address TRM 3.7.2 and Enter Condition A.
After shutdown of the HWC System, high vibration alarms on Reactor Recirculation Pump 3A will have the crew respond JAW the ARPs. The ARPs will direct the operators to adjust RR Pump 3A speed in an attempt to lower vibrations on RR Pump 3A. Once speed is adjusted, high vibration alarm will clear and vibrations will lower.
After the RR Pump 3A vibrations is addressed, HPCI will inadvertently initiate. The crew will verify the initiation is inadvertent and trip and lockout HPCI. The SRO will address Technical Specification 3.5.1 and Enter Condition C.
Shortly after the HPCI initiation a steam leak will develop in the HPCI Room, HPCI will fail to automatically and manually isolate. When attempting to manually isolate HPCI steam valve 73-2 the 3A RMOV Board will be lost due to an electrical fault.
The crew will enter EOI-3 and scram the Reactor. All rods will insert on the scram and level and pressure will be controlled JAW EOI-1. The crew should lower reactor pressure. As the second MAX safe temperature is approached, the crew should anticipate Emergency Depressurization and when the second MAX safe temperature is reached the crew will Emergency Depressurize.
During ED one ADS valve will fail and the operator will open an additional SRV. After ED, the startup level controller will fail. The crew will control level with Core Spray Loop 2 and place R}JR Loop 2 in Suppression Pool Cooling.
The Emergency classification is 3.1-S Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner.
All Control Rods are inserted.
Emergency Depressurization complete.
Reactor Level is restored and maintained.

Appendix D Scenario Outline Form ES-D-1 Scenario Summary:
BOP will perform Stroke Time Test on 3-FCV-43.13 and 3-FCV-43-14 with 3-FSV-43-14 failing the stroke time test. SRO will determine Technical Specification 3.6.1.3 Condition A required.
Then, the ATC will raise power with Reactor Recirculation flow to 95%.
Once evaluators satisfied with Reactivity Manipulations, the VFD Cooling Water Pump for the B Reactor Recirc VFD will trip and the standby pump will fail to start. The ATC will start the standby VFD Cooling Water Pump to restore cooling water preventing a VFD and Reactor Recirc Pump trip.
Steam Packing Exhauster will trip and the STBY Exhauster will Start but the discharge damper will fail to open. The BOP will open the Steam Packing Exhauster discharge damper and restore Steam Packing Exhauster operation JAW with ARPs.
A leak will develop on RHR Loop 1 common minimum flow line, field reports will indicate the leak can be isolated by closing RHR A and C Pump suction valves. Once suction valves are closed SRO will determine Technical Specification 3.5.1 Condition A is required, TS 3.6.2.3 Condition B, 3.6.2.4 Condition B, and 3.6.2.5 Condition B all 7 Days.
After RHR Loop 1 is isolated an RBCCW Pump will trip and the sectionalizing valve will fail to close automatically. Operators will take actions JAW 3-AOI-70-1 and trip RWCU Pumps and close the sectionalizing valve for RBCCW.
A LOCA will occur, RPS will fail to de-energize, the crew will scram the Reactor by arming and depressing ARI, and enter EOI-1 and EOI-2. All rods will insert on ART, level control will be on feedwater and pressure control will be on SRVs(only three SRVs are available. The bypass valves fail closed during the scram. The LOCA will cause increasing DW Pressure and Temperature; the crew will take action JAW EOI-2. When the crew attempts to spray the Drywell, the Drywell Spray valves will fail to open. Unable to spray the drywell the crew will need to establish limits for DW pressure and temperature for anticipating ED and ED.
The Emergency classification is 2.1-A Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner.
All Control Rods are inserted.
Emergency Depressurization is complete Reactor Level is restored and maintained.

Appendix P Scenario Outline Form ES-P-i Scenario Summary:
The Plant is operating at 4% Reactor Power.
The BOP Operator will Aligning Charcoal Filters for Parallel Flow JAW 3-01-66 section 5.11.
The ATC will withdraw control rods in order to raise power to 8% for a mode change from 2 to 1.
Once the NRC is satisfied with the reactivity manipulation, Reactor Recirculation Pump B will trip.
The SRO will direct entry to 3-A0I-68-1A, the ATC will close RR Pump B discharge valve.
The SRO will evaluate Technical Specification 3.4.1 Condition A is required.
Core Spray Pump 3A inadvertently initiates with loss of minimum flow protection. BOP Operator verifies initiation is inadvertent and with SRO concurrence stop Core Spray Pump 3A JAW with ARPs. The SRO will evaluate Technical Specification 3.5.1 Condition A is required.
The Steam Seal regulator will fail, the BOP Operator will take action JAW with the ARPs and restore steam seal pressure with the bypass valve.
The operating feedwater pump controller will fail, level will slowly rise until the ATC or Crew notices the Reactor Level change. The controller will fail to respond until the ATC takes manual control with handswitch. The Operator will be able to maintain Reactor Level control in manual.
SRO should direct entry into 3-AOI-3-l.
An unisolable Torus leak will commence. Suppression Pool level will start to lower and continue to lower. The SRO will enter EOI-3 on flood alarms and eventually EOI-2 on Suppression Pool Level.
The SRO will determine that Suppression Pool level cannot be maintained above 11.5 feet and enter E0I-l to scram the reactor and then to Emergency Depressurize.
An ATWS will exist on the scram, the crew will work through EOI-1 and C-S to insert control rods, maintain reactor level and pressure. The SRO will transition to C-2 to Emergency Depressurize.
Attempts to add water to the suppression pool will be unsuccessful with the failure of 3-FCV-73-30 and 3-FCV-74-57.
The Emergency Classification is 1.2-S Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner:
All but six Control Rods are inserted Emergency Depressurization complete Reactor Level is restored and maintained

Appendix D Scenario Outline Form ES-D-1 Scenario Summary:
BOP will remove LPRM 8-49B from bypass JAW 2-OI-92B section 6.4.
ATC will raise Reactor Power with control rods as directed by the Reactivity Control Plan.
During power ascension Control Rod 14-3 5 will experience an RPIS position failure. The crew will respond JAW ARPs and 2-AOI-85-4. The ATC will insert Control Rod 14-3 5 one notch to establish position indication. After Control Rod 14-3 5 is inserted it will begin to drift in, the ATC will respond JAW 2-AOI-85-5 and insert the control rod to position 00.
EECW D3 Pump will trip and the standby EECW Pump B3 will fail to auto start, the BOP will respond JAW ARPs and start EECW Pump B3 to EECW flow to the north header.
The SRO will evaluate Technical Specification 3.7.2 and Condition A is entered.
Outboard MSIV D will drift closed, the crew will respond JAW 2-AOI-1-3. The ATC will lower Reactor Power to less than 66% and the BOP will fully close Outboard MSIV D. The SRO will evaluate Technical Specification 3.6.1.3 and Condition A is entered.
Feedwater Flow Transmitters will fail the crew will respond JAW ARPs and 2-AOI-3 -1, the ATC will report that Feedwater Level Control transferred to single element and will transfer to single element. Reactor Level will stabilize after the initial transient.
Vacuum will begin to degrade and the crew will respond JAW 2-AOI-47-3, the crew will insert a manual Reactor scram prior to the Main Turbine trip. An ATWS will exist and the crew will enter EOI- 1 and C-5.
After the scram and airline break will occur in the drywell causing MSJV closure and transition to SRVs for pressure control and RCIC for level control. Until the crew performs Appendix 8G, SRV operation will degrade due to the loss of air.
CRD Pump 2A will trip and the ATC will start CRD Pump lB in order to insert control rods.
The crew will maintain directed level and pressure bands, insert all control rods and enter EOI-2 and place RHR in Suppression Pool Cooling.
The Emergency Classification is 1.2-S Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner.
Controls Rods are being inserted Reactor Level is being maintained in directed level band
