H B Robinson 2016 NRC Scenario #1 The plant is at 100% power (MOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.7.4 ACTION A. FI-613, CCW System Flow is OOS (I&C Investigating). RTGB Annunciator APP-010-B3, EDG B START AIR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.
Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.
During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.
Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.
On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Appendix D                                Scenario Outline                            Form ES-D-1 (Rev_010516) initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.
During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.
The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)
Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based)
Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

HB Robinson 2016 NRC Scenario #2 The plant is at 75% power (BOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.
Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.
Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.
Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event.
Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function.
When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.
Appendix D                                  Scenario Outline                            Form ES-D-1 (Rev_011416)
The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied: SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.
Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)
Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.
Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)
Safety Significance:      Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.
Appendix D                                Scenario Outline                          Form ES-D-1 (Rev_011416)
In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).
Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

H B Robinson 2016 NRC Scenario #3 The plant is at 68% power (EOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days.
Technical Specification LCO 3.7.4 ACTION C has just been entered. Maintenance reports that this pump will be OPERABLE in 2 hours, and station management has directed that the initiation of the shutdown be delayed 2 hours. TI-471, PRT Temperature is OOS (I&C Investigating).
RTGB Annunciator APP-008-C3, EMERG OIL PMP OVLD, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources - Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.
Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).
Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.
During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.
Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).
After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.
Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response.
However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.
Appendix D                                  Scenario Outline                        Form ES-D-1 (Rev_010616)
The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.
Critical Tasks:
Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Manually close the OPEN Pzr Spray Valve(s) and the Stuck Open PORV Block Valve before the Reactor trips based on low pressurizer pressure.
Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)
Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.
Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)
Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

HB Robinson 2016 NRC Scenario #4 The plant is at 25% power (BOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.
After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135°F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.
Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP).
The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.
Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.
Appendix D                                  Scenario Outline                            Form ES-D-1 (Rev_011516)
Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes),
and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.
The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.
Although the challenge was not initiated by the operator (was not initiated by operator error),
continuation of the challenge is a result of the operators failure to insert negative reactivity.
Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.
Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

Turnover:              The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating).

H B Robinson 2016 NRC Scenario #5 The plant is at 3-5% power (EOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.
Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.
When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine. The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.
Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail. The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI).
The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.
Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.
Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.
Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.
The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.
Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.
While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.
The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions Appendix D                                  Scenario Outline                        Form ES-D-1 (Rev_111915) taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.
Critical Tasks:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety.
It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

The following equipment is Out-Of-Service: The following equipment is Out-Of-Service: The A EDG is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.8.1 ACTION B.1, B.2, B.3.2.1 and B.3.2.2, and B.4. R-15, Condenser Air Ejector Gas Radiation Monitor is OOS (I&C Investigating). RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).
Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.
After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.
After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.
Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).
Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.
Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.
Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.
Appendix D                                Scenario Outline                        Form ES-D-1 (Rev_010716)
The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.
Critical Tasks:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room.
Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.
Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG.
The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.
Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.
During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.
Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.
On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Scenario Event Description NRC Scenario 1 initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.
During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.
The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)
Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based, if above 100% WR level see Simulator Code thlecell(193) to determine)
Safety Significance:      Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

== Description:==
C Steam Generator Tube Rupture/Loss of Off-Site Power On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs. During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV. The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Task:
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (If above 100% WR level see Simulator Code thlecell(193) to determine)
Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
At the discretion of the Lead Examiner terminate the exam.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating).
The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.
Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS)
Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.
Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.
Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Scenario Event Description NRC Scenario 2 Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.
The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied: SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13&deg;F [32&deg;F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200&deg;F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.
Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)
Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room.
Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.
Scenario Event Description NRC Scenario 2 Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)
Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.
In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).
Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Cold Leg SBLOCA/480 VAC Bus E-1 De-energizes /C SI Pump fails to Auto Start/ CV Spray Valves SI-880C and D fail to OPEN Automatically Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop.
The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump. Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves. The scenario will terminate in EOP-E-1 after Containment pressure has been lowered to less than 10 psig, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure.

Critical Task:
Establish flow from at least one high-head SI pump before transition out of E-0 Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied:
SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13&deg;F [32&deg;F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops.
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200&deg;F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Critical Task:
Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2 Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component. In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity). Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days. Technical Specification LCO 3.7.4 ACTION C has just been entered. Maintenance reports that this pump will be OPERABLE in 2 hours, and station management has directed that the initiation of the shutdown be delayed 2 hours.

Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources -
Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.
Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).
Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.
During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.
Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).
After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.
Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The Scenario Event Description NRC Scenario 3 operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.
The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.
Critical Tasks:
Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Manually close the OPEN Pzr Spray Valve(s) and the Block Valve for the Stuck Open PORV before the Reactor trips based on low pressurizer pressure.
Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)
Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.
Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)
Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.

BOP      (Step 2.b) All MSR Purge AND Shutoff Valves - CLOSED Critical Task:
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.
After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135&deg;F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.
Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP). The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.
Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Scenario Event Description NRC Scenario 4 Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.
Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.
The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF. Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.
Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.
Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Scenario Event Description NRC Scenario 4 Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST. Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition. The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Task:
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.
Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs; and result in a mechanical failure due to Pressurized Thermal Shock.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.
Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.
When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine.
The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.
Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail.
The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI). The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.
Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.
Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.
Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.
The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.
Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.
While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.
Scenario Event Description NRC Scenario 5 The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.
Critical Tasks:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

== Description:==
Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically. The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor. Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Loss of Reactor or Secondary Coolant, and lower AFW flow to each Steam Generator to 60 gpm. While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure will rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2. The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators.

== Description:==
Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos.                Expected Actions/Behavior                  Comments Critical Task:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions.
Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

== Description:==
Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos.                  Expected Actions/Behavior                  Comments Critical Task:
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.
After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.
After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.
Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).
Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.
Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.
Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.
Scenario Event Description NRC Scenario 6 The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.
Critical Tasks:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals.
Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.
Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

== Description:==
Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started. Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018. The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos.                  Expected Actions/Behavior                            Comments Critical Task:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos.                  Expected Actions/Behavior                          Comments Critical Task:
Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

H B Robinson 2016 NRC Scenario #1 The plant is at 100% power (MOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.7.4 ACTION A. FI-613, CCW System Flow is OOS (I&C Investigating). RTGB Annunciator APP-010-B3, EDG B START AIR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.
Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.
During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.
Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.
On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Appendix D                                Scenario Outline                            Form ES-D-1 (Rev_010516) initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.
During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.
The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38&deg;F of RCS Subcooling OR (2) below 295&deg;F (RCS Integrity Red Path Limit) (EOP-Based)
Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based)
Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

HB Robinson 2016 NRC Scenario #2 The plant is at 75% power (BOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.
Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.
Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.
Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event.
Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function.
When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.
Appendix D                                  Scenario Outline                            Form ES-D-1 (Rev_011416)
The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied: SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13&deg;F [32&deg;F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200&deg;F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.
Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)
Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.
Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)
Safety Significance:      Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.
Appendix D                                Scenario Outline                          Form ES-D-1 (Rev_011416)
In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).
Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

H B Robinson 2016 NRC Scenario #3 The plant is at 68% power (EOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days.
Technical Specification LCO 3.7.4 ACTION C has just been entered. Maintenance reports that this pump will be OPERABLE in 2 hours, and station management has directed that the initiation of the shutdown be delayed 2 hours. TI-471, PRT Temperature is OOS (I&C Investigating).
RTGB Annunciator APP-008-C3, EMERG OIL PMP OVLD, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources - Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.
Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).
Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.
During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.
Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).
After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.
Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response.
However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.
Appendix D                                  Scenario Outline                        Form ES-D-1 (Rev_010616)
The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.
Critical Tasks:
Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Manually close the OPEN Pzr Spray Valve(s) and the Stuck Open PORV Block Valve before the Reactor trips based on low pressurizer pressure.
Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)
Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.
Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)
Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

HB Robinson 2016 NRC Scenario #4 The plant is at 25% power (BOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.
After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135&deg;F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.
Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP).
The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.
Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.
Appendix D                                  Scenario Outline                            Form ES-D-1 (Rev_011516)
Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes),
and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.
The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.
Although the challenge was not initiated by the operator (was not initiated by operator error),
continuation of the challenge is a result of the operators failure to insert negative reactivity.
Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.
Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

H B Robinson 2016 NRC Scenario #5 The plant is at 3-5% power (EOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.
Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.
When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine. The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.
Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail. The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI).
The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.
Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.
Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.
Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.
The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.
Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.
While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.
The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions Appendix D                                  Scenario Outline                        Form ES-D-1 (Rev_111915) taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.
Critical Tasks:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety.
It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

HB Robinson 2016 NRC Scenario #6 The plant is at 100% power (MOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The following equipment is Out-Of-Service: The A EDG is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.8.1 ACTION B.1, B.2, B.3.2.1 and B.3.2.2, and B.4. R-15, Condenser Air Ejector Gas Radiation Monitor is OOS (I&C Investigating). RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).
Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.
After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.
After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.
Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).
Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.
Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.
Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.
Appendix D                                Scenario Outline                        Form ES-D-1 (Rev_010716)
The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.
Critical Tasks:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room.
Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.
Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG.
The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.7.4 ACTION A. FI-613, CCW System Flow is OOS (I&C Investigating). RTGB Annunciator APP-010-B3, EDG B START AIR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation.
Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.
Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.
During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.
Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.
On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Scenario Event Description NRC Scenario 1 initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.
During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.
The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38&deg;F of RCS Subcooling OR (2) below 295&deg;F (RCS Integrity Red Path Limit) (EOP-Based)
Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.
Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based, if above 100% WR level see Simulator Code thlecell(193) to determine)
Safety Significance:      Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

== Description:==
C Steam Generator Tube Rupture/Loss of Off-Site Power On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.
Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs. During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV. The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Task:
Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

* MAINTAIN Core Exit T/Cs  LESS THAN REQUIRED TEMPERATURE Critical Task:
While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38&deg;F of RCS Subcooling OR (2) below 295&deg;F (RCS Integrity Red path Limit)
Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (If above 100% WR level see Simulator Code thlecell(193) to determine)
Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
At the discretion of the Lead Examiner terminate the exam.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating).
The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.
Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS)
Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.
Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.
Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Scenario Event Description NRC Scenario 2 Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.
The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied: SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13&deg;F [32&deg;F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200&deg;F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.
Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)
Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room.
Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.
Scenario Event Description NRC Scenario 2 Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)
Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.
In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).
Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

C FRV Controller fails HIGH in AUTO Time Pos.                Expected Actions/Behavior                      Comments Critical Task:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Cold Leg SBLOCA/480 VAC Bus E-1 De-energizes /C SI Pump fails to Auto Start/ CV Spray Valves SI-880C and D fail to OPEN Automatically Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop.
The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump. Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves. The scenario will terminate in EOP-E-1 after Containment pressure has been lowered to less than 10 psig, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure.

Critical Task:
Establish flow from at least one high-head SI pump before transition out of E-0 Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B  ACTUATED, OR BOTH of the following satisfied:
SI Pumps  AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs  LESS THAN 13&deg;F [32&deg;F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops.
Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200&deg;F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Critical Task:
Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2 Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component. In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity). Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days. Technical Specification LCO 3.7.4 ACTION C has just been entered. Maintenance reports that this pump will be OPERABLE in 2 hours, and station management has directed that the initiation of the shutdown be delayed 2 hours. TI-471, PRT Temperature is OOS (I&C Investigating). RTGB Annunciator APP-008-C3, EMERG OIL PMP OVLD, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources -
Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.
Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).
Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.
During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.
Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).
After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.
Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.
Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The Scenario Event Description NRC Scenario 3 operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.
The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.
Critical Tasks:
Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Manually close the OPEN Pzr Spray Valve(s) and the Block Valve for the Stuck Open PORV before the Reactor trips based on low pressurizer pressure.
Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)
Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.
Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)
Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

Inadvertent FWIS/ Turbine fails to Trip/GV Valves fail to Runback/MSI fails to AUTO Actuate/ A & B MDAFW Pump Trip After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur. Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start. The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

* IF Turbine will NOT trip, THEN manually RUNBACK Turbine at maximum rate UNTIL ALL Governor valves are CLOSED.
* IF Turbine can NOT be runback, THEN manually CLOSE MSIVs AND MSIV Bypass Valves.
BOP      (Step 2.b) All MSR Purge AND Shutoff Valves - CLOSED Critical Task:
Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

      *  (N)ormal,    (R)eactivity,    (I)nstrument,    (C)omponent,    (M)ajor Scenario Event Description NRC Scenario 4 HB Robinson 2016 NRC Scenario #4 The plant is at 25% power (BOL). The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.
After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).
During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135&deg;F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.
Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP). The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.
Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)
Instrumentation.
Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.
Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Scenario Event Description NRC Scenario 4 Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.
Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.
The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.
Critical Tasks:
Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.
Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF. Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.
Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.
Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Scenario Event Description NRC Scenario 4 Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

== Description:==
ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST. Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition. The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Task:
Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)
Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.
Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of FRP-P.1 Occurs (EOP-Based)
Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.
Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs; and result in a mechanical failure due to Pressurized Thermal Shock.

The area has experienced steady light rain for the past 6 hours, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.
The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.
Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.
When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine.
The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.
Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail.
The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI). The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.
Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.
Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.
Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.
The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.
Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.
While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.
Scenario Event Description NRC Scenario 5 The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.
Critical Tasks:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

== Description:==
Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically. The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor. Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Loss of Reactor or Secondary Coolant, and lower AFW flow to each Steam Generator to 60 gpm. While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure will rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2. The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators.

== Description:==
Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos.                Expected Actions/Behavior                  Comments Critical Task:
Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions.
Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos.                  Expected Actions/Behavior                  Comments Critical Task:
Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).
Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.
After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.
After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.
Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).
Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.
Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.
Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.
Scenario Event Description NRC Scenario 6 The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.
Critical Tasks:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals.
Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.
Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos.                  Expected Actions/Behavior                            Comments Critical Task:
Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

* RESET SPDS AND Initiate MONITORING Critical Safety Function Status Trees.

H B Robinson 2016 NRC Scenario #1 The plant is at 100% power (MOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The SDAFW Pump is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.7.4 ACTION A. FI-613, CCW System Flow is OOS (I&C Investigating). RTGB Annunciator APP-010-B3, EDG B START AIR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating).

Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.

Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.

During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.

Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.

On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Appendix D Scenario Outline Form ES-D-1 (Rev_010516) initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.

During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.

The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)

Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)

Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Initial Conditions: The plant is at 75% power (BOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

Turnover: The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating).

HB Robinson 2016 NRC Scenario #2 The plant is at 75% power (BOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.

Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.

Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.

Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event.

Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.

Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function.

When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.

Appendix D Scenario Outline Form ES-D-1 (Rev_011416)

The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B ACTUATED, OR BOTH of the following satisfied: SI Pumps AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)

Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)

Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)

Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.

Appendix D Scenario Outline Form ES-D-1 (Rev_011416)

In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).

Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

H B Robinson 2016 NRC Scenario #3 The plant is at 68% power (EOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days.

Technical Specification LCO 3.7.4 ACTION C has just been entered. Maintenance reports that this pump will be OPERABLE in 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, and station management has directed that the initiation of the shutdown be delayed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. TI-471, PRT Temperature is OOS (I&C Investigating).

RTGB Annunciator APP-008-C3, EMERG OIL PMP OVLD, has failed to the ILLUMINATED condition (I&C is investigating).

Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources - Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.

Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).

Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.

During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.

Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).

After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.

Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response.

However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.

Appendix D Scenario Outline Form ES-D-1 (Rev_010616)

The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

Critical Tasks:

Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Manually close the OPEN Pzr Spray Valve(s) and the Stuck Open PORV Block Valve before the Reactor trips based on low pressurizer pressure.

Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)

Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)

Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

The operator will place the B Primary Water Pump in service and continue with the startup.

After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135°F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.

Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP).

The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.

Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.

Appendix D Scenario Outline Form ES-D-1 (Rev_011516)

Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes),

and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.

The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.

Although the challenge was not initiated by the operator (was not initiated by operator error),

continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.

Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.

Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.

When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine. The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.

Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail. The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI).

The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.

Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.

Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.

Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.

The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.

Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.

While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.

The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions Appendix D Scenario Outline Form ES-D-1 (Rev_111915) taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.

Critical Tasks:

Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety.

It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).

Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.

After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.

After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.

Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).

Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.

Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.

Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.

Appendix D Scenario Outline Form ES-D-1 (Rev_010716)

The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.

Critical Tasks:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room.

Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG.

The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation.

Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.

Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.

During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.

Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.

On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Scenario Event Description NRC Scenario 1 initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.

During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.

The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)

Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)

Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based, if above 100% WR level see Simulator Code thlecell(193) to determine)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Description:

C Steam Generator Tube Rupture/Loss of Off-Site Power On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs. During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV. The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Task:

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

RO (Step 23) STOP SI Pumps Critical Task:

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (If above 100% WR level see Simulator Code thlecell(193) to determine)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

At the discretion of the Lead Examiner terminate the exam.

The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.

Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS)

Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.

Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.

Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.

Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Scenario Event Description NRC Scenario 2 Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.

The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B ACTUATED, OR BOTH of the following satisfied: SI Pumps AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)

Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)

Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room.

Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Scenario Event Description NRC Scenario 2 Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)

Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.

In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).

Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Cold Leg SBLOCA/480 VAC Bus E-1 De-energizes /C SI Pump fails to Auto Start/ CV Spray Valves SI-880C and D fail to OPEN Automatically Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop.

The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump. Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves. The scenario will terminate in EOP-E-1 after Containment pressure has been lowered to less than 10 psig, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure.

Critical Task:

Establish flow from at least one high-head SI pump before transition out of E-0 Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Critical Task:

Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2 Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component. In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity). Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources -

Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.

Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).

Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.

During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.

Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).

After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.

Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The Scenario Event Description NRC Scenario 3 operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.

The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

Critical Tasks:

Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Manually close the OPEN Pzr Spray Valve(s) and the Block Valve for the Stuck Open PORV before the Reactor trips based on low pressurizer pressure.

Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)

Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)

Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

Description:

Inadvertent FWIS/ Turbine fails to Trip/GV Valves fail to Runback/MSI fails to AUTO Actuate/ A & B MDAFW Pump Trip After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur. Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start. The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

Inadvertent FWIS/ Turbine fails to Trip/GV Valves fail to Runback/MSI fails to AUTO Actuate/ A & B MDAFW Pump Trip Time Pos. Expected Actions/Behavior Comments

  • IF Turbine will NOT trip, THEN manually RUNBACK Turbine at maximum rate UNTIL ALL Governor valves are CLOSED.
  • IF Turbine can NOT be runback, THEN manually CLOSE MSIVs AND MSIV Bypass Valves.

BOP (Step 2.b) All MSR Purge AND Shutoff Valves - CLOSED Critical Task:

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

  • (N)ormal, (R)eactivity, (I)nstrument, (C)omponent, (M)ajor Scenario Event Description NRC Scenario 4 HB Robinson 2016 NRC Scenario #4 The plant is at 25% power (BOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.

After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135°F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.

Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP). The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.

Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Scenario Event Description NRC Scenario 4 Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.

Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.

The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF. Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.

Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Scenario Event Description NRC Scenario 4 Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

  • If unable to control S/G level, THEN Critical Task:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Description:

ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST. Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.

  • Rod position indicators FULLY INSERTED
  • Rod Bottom Lights ILLUMINATED
  • Neutron flux - LOWERING RO (Step 1 RNO) PERFORM the following: Immediate Action
  • Manually TRIP Reactor.

Critical Task:

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.

Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs; and result in a mechanical failure due to Pressurized Thermal Shock.

  • (N)ormal, (R)eactivity, (I)nstrument, (C)omponent, (M)ajor Scenario Event Description NRC Scenario 5 H B Robinson 2016 NRC Scenario #5 The plant is at 3-5% power (EOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.

Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.

When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine.

The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.

Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail.

The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI). The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.

Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.

Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.

Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.

The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.

Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.

While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.

Scenario Event Description NRC Scenario 5 The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.

Critical Tasks:

Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically. The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor. Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Loss of Reactor or Secondary Coolant, and lower AFW flow to each Steam Generator to 60 gpm. While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure will rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.

Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Description:

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos. Expected Actions/Behavior Comments Critical Task:

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).

Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.

After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.

After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.

Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).

Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.

Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.

Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.

Scenario Event Description NRC Scenario 6 The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.

Critical Tasks:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals.

Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Description:

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos. Expected Actions/Behavior Comments Critical Task:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

  • Establish Seal Injection flow
  • CHECK adequate DSDG OR EDG capacity to run one Charging Pump (108 KW each) (DSDG preferred)

Description:

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos. Expected Actions/Behavior Comments Critical Task:

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

FI-613, CCW System Flow is OOS (I&C Investigating). RTGB Annunciator APP-010-B3, EDG B START AIR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating).

Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.

Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.

During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.

Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.

On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Appendix D Scenario Outline Form ES-D-1 (Rev_010516) initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.

During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.

The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)

Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)

Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

HB Robinson 2016 NRC Scenario #2 The plant is at 75% power (BOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.

Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.

Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.

Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event.

Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.

Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function.

When this occurs, the B CV Spray will automatically start on HI-HI Containment Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.

Appendix D Scenario Outline Form ES-D-1 (Rev_011416)

The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B ACTUATED, OR BOTH of the following satisfied: SI Pumps AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)

Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)

Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)

Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.

Appendix D Scenario Outline Form ES-D-1 (Rev_011416)

In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).

Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

The following equipment is Out-Of-Service: The SDAFW Pump is OOS, and has been for 7 days.

Maintenance reports that this pump will be OPERABLE in 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, and station management has directed that the initiation of the shutdown be delayed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. TI-471, PRT Temperature is OOS (I&C Investigating).

RTGB Annunciator APP-008-C3, EMERG OIL PMP OVLD, has failed to the ILLUMINATED condition (I&C is investigating).

Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources - Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.

Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).

Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.

During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.

Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).

After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.

Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response.

However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.

Appendix D Scenario Outline Form ES-D-1 (Rev_010616)

The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

Critical Tasks:

Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Manually close the OPEN Pzr Spray Valve(s) and the Stuck Open PORV Block Valve before the Reactor trips based on low pressurizer pressure.

Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)

Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)

Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

HB Robinson 2016 NRC Scenario #4 The plant is at 25% power (BOL). The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.

After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135°F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.

Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP).

The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.

Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.

Appendix D Scenario Outline Form ES-D-1 (Rev_011516)

Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes),

and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.

The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.

Although the challenge was not initiated by the operator (was not initiated by operator error),

continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.

Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.

Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.

When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine. The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.

Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail. The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI).

The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.

Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.

Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.

Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.

The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.

Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.

While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.

The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions Appendix D Scenario Outline Form ES-D-1 (Rev_111915) taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.

Critical Tasks:

Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety.

It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The following equipment is Out-Of-Service: The A EDG is OOS. ACTION has been taken in accordance with Technical Specification LCO 3.8.1 ACTION B.1, B.2, B.3.2.1 and B.3.2.2, and B.4. R-15, Condenser Air Ejector Gas Radiation Monitor is OOS (I&C Investigating). RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).

Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.

After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.

After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.

Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).

Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.

Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.

Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.

Appendix D Scenario Outline Form ES-D-1 (Rev_010716)

The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.

Critical Tasks:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room.

Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG.

The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Shortly after taking the watch, Pressurizer Level Transmitter, LT-459 will fail LOW causing normal letdown to isolate, de-energizing of pressurizer control group heaters and charging pump speed to rise for the pump in AUTO. The operator will respond in accordance APP-003-E8, PZR CONTROL HI/LO LVL, and AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-030, Pressurizer Level Transmitters. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation.

Following this, the controlling steam flow channel for S/G C, FT-494, will fail LOW, causing FRV-498 to start to CLOSE. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-034, Steam Flow. The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation.

Next, a tube leak will develop in Feed Water Heater 4A. The operator will respond in accordance with APP-007-E7, HTR 4A HI/LO LVL, identifying the leak. The operator may enter AOP-010, Main Feedwater/Condensate Malfunction. Ultimately, the operator will use OP-407, Heater Drain and Vents, to remove Feedwater Heaters 5A, 4A, and 3A from Service. This will require a power decrease. The operator will use either AOP-038, Rapid Downpower, or OP-105, Maneuvering the Plant When > 25% Power, and OP-301, Chemical and Volume Control System (CVCS), to lower plant power.

During the downpower, the A CRDM Fan will trip. The operator will address APP-010-A6, HVH-5A/B AIR FLOW LOST/OVLD, and manually start the B CRDM Fan.

Shortly afterwards, a continuous control rod insertion will occur. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System. The operator will be unable to control the rod insertion and will manually trip the reactor.

On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-Scenario Event Description NRC Scenario 1 initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs.

During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV.

The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs (EOP-Based)

Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

While in EOP-E-3, establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either (1) Too high to maintain 38°F of RCS Subcooling OR (2) below 295°F (RCS Integrity Red Path Limit) (EOP-Based)

Safety Significance: Failure to establish and maintain the correct RCS temperature during a SGTR leads to a transition from E-3 to a contingency procedure. This failure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (EOP-Based, if above 100% WR level see Simulator Code thlecell(193) to determine)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Description:

C Steam Generator Tube Rupture/Loss of Off-Site Power On the reactor trip, a 500 gpm Steam Generator Tube Rupture will occur (over 10 minutes) on the C Steam Generator. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. After the Immediate Actions are complete, it is likely that the operator will determine that SI is NOT actuated nor required, and transition to EOP-ES-0.1, Reactor Trip Response. While in this procedure the operator will determine that SI is required, manually actuate SI, and return to EOP-E-0. Upon completion of EOP-E-0, the operator will transition to EOP-E-3, Steam Generator Tube Rupture, to isolate the flow into and out of the C Steam Generator and then conduct a cooldown of the RCS.

Upon transition into EOP-E-3, a Loss of Off-Site Power will occur. Both EDGs will start and re-power Buses E-1 and E-2. With SI previously reset, the operator will need to address a re-initiation of AFW flow to all Steam Generators, and the restart of the ECCS Pumps. The operator will continue with EOP-E-3 and conduct the RCS cooldown using the A and B Steam Generator PORVs. During the RCS depressurization, the Pzr Spray Valves will not be available. The operator will be required to conduct the depressurization using an available Pzr PORV. The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Critical Task:

Isolate feedwater flow into and steam flow from the ruptured SG before a transition to ECA-3.1 occurs Safety Significance: Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. The fact that the operator allows the differential pressure to dissipate and, as a result, are then forced to transition to a contingency procedure constitutes an incorrect performance that necessitates the operator taking compensating action that would unnecessarily complicate the event mitigation strategy.

Depressurize the RCS to meet SI termination criteria before Steam Generator Overfill is reached based on Water in the Steam Lines. (If above 100% WR level see Simulator Code thlecell(193) to determine)

Safety Significance: Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS (when it is possible to do so) needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

At the discretion of the Lead Examiner terminate the exam.

The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. The C Charging Pump is also OOS. LI-928, C SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-009-C3, AIR SIDE SEAL OIL BU PMP OVLD, has failed to the EXTINGUISHED condition (I&C is investigating).

The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase, VCT Level Transmitter LT-115 will fail HIGH causing all letdown to be diverted to the CVCS HUTs. This failure will result in VCT level lowering without automatic makeup. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will be suspended.

Next, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure, and place all Feed Regulating Valves in MANUAL The operator will remove the failed instrument from service in accordance with OWP-033, First Stage Pressure (FSP), and restore the Feed Regulating valves to AUTO control. The operator will address 3.3.1, Reactor Protection System (RPS) Instrumentation, Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS)

Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Following this, the B Charging Pump will trip. The operator will respond in accordance with APP-003-F5, CHG PMP MOTOR OVLD/TRIP and raise speed of the A Charging Pump. The operator may enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The operator will address 3.4.17, Chemical and Volume Control System.

Shortly afterwards, the C Feed Regulating Valve Controller will fail such that the valve starts to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and control the C S/G level manually.

Subsequently, a Cold Leg Small Break LOCA will occur (over 5 minutes) on the B Loop. The operator will enter AOP-016, Excessive Primary Plant Leakage. Ultimately, the operator will enter EOP-E-0, Reactor Trip or Safety Injection. When the reactor trips, the normal supply breaker to Bus E-1 will trip OPEN, and the A EDG Output Breaker will fail to CLOSE either automatically or manually; and Train A equipment will remain unavailable throughout the event. Additionally, the C SI Pump will fail to automatically start on SI, and the operator will be required to manually start this pump.

Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant, and the break size will become larger. Eventually, Containment pressure will exceed 10 psig creating an Orange Path condition on the Containment Critical Safety Function. When this occurs, the B CV Spray will automatically start on HI-HI Containment Scenario Event Description NRC Scenario 2 Pressure, however, both SI-880C&D (B CV Spray Pump Discharge Valves) will fail to open automatically, and the operator will be required to manually open these valves.

The scenario will terminate in EOP-E-1 after Containment Spray has been initiated, or at Step 9 of FRP-J.1, Response to High Containment Pressure, after the operator has taken all necessary steps to reduce Containment pressure, or upon transition from either EOP-E-1 or FRP-J.1 to FRP-P.1, Response to Imminent Pressurized Thermal Shock (After all Critical Tasks have been completed).

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B ACTUATED, OR BOTH of the following satisfied: SI Pumps AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops. (EOP-Based)

Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

Establish flow from at least one high-head SI pump before transition out of E-0. (EOP-Based)

Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room.

Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Scenario Event Description NRC Scenario 2 Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2. (EOP-Based)

Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component.

In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity).

Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Critical Task:

Establish flow from at least one high-head SI pump before transition out of E-0 Safety Significance: Failure to manually start at least one high-head SI pump under the postulated conditions constitutes mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity. In this case, at least one high-head SI pump can be manually started from the control room. Therefore, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario. Additionally, failure to manually start a high-head SI pump also represents a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Finally, under the postulated plant conditions, failure to manually start a high-head SI pump (when it is possible to do so) is a violation of the facility license condition.

Description:

Cold Leg SBLOCA/480 VAC Bus E-1 De-energizes /C SI Pump fails to Auto Start/ CV Spray Valves SI-880C and D fail to OPEN Automatically Time Pos. Expected Actions/Behavior Comments Critical Task:

Trip all RCPs within 6 minutes of meeting the EOP-E-0/E-1 RCP Trip Criteria (Containment Isolation Phase B ACTUATED, OR BOTH of the following satisfied:

SI Pumps AT LEAST ONE RUNNING AND CAPABLE OF DELIVERING FLOW AND RCS Subcooling based on Core Exit T/Cs LESS THAN 13°F [32°F]) so that CET temperatures do not become superheated when forced circulation in the RCS stops.

Safety Significance: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200°F, which is the limit specified in the ECCS acceptance criteria. Thus, failure to perform the task represents mis-operation or incorrect operator performance in which the operator has failed to prevent degradation of the fuel cladding barrier to fission product release and which leads to a violation of the facility license condition.

VALVE, as necessary.

Critical Task:

Manually actuate at least one CV Spray Train before Transitioning to EOP-ES-1.2 Safety Significance: Failure to manually actuate the minimum required complement of containment cooling equipment under the postulated conditions demonstrates the inability of the crew to recognize a failure or an incorrect automatic actuation of an ESF system or component. In this case, the minimum required complement of containment cooling equipment can be manually actuated from the control room. Therefore, failure to manually actuate the minimum required complement of containment cooling equipment also represents a failure by the operator to demonstrate the ability to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent (degraded emergency core cooling system (ECCS) capacity). Additionally, under the postulated plant conditions, failure to manually actuate the minimum required complement of containment cooling equipment (when it is possible to do so) results in a failure to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Shortly after taking the watch, Instrument Bus 3 will de-energize. The operator will respond in accordance with AOP-024, Loss of Instrument Bus, and restore power to the Bus. The operator will address Technical Specification LCO 3.8.7, AC Instrument Bus Sources -

Operating, and Technical Specification LCO 3.8.9, Distribution Systems-Operating.

Following this, the controlling feed flow channel for S/G B, FT-487, will fail LOW, causing FRV-498 to start to OPEN. The operator will respond in accordance with AOP-010, Main Feedwater/Condensate Malfunction, and/or AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-026, Feed Flow (FWF).

Next, the WCCS will call and inform the operator that it has been determined that the SDAFW Pump will not be restored to OPERABLE status within the next two hours as expected, and that station management has directed that the plant be brought to Mode 3 within the next four hours using AOP-038, Rapid Downpower.

During the downpower, the Letdown Pressure Control Valve (PCV-145) controller will fail such that the valve will fail closed. The operator will respond in accordance with APP-001-D6, LP LTDN LN HI PRESS, and ultimately take manual control of the valve.

Shortly afterwards, PZR Pressure transmitter PT-444 will fail HIGH causing the Pzr Spray valves and Pzr PORV to OPEN. The operator will respond in accordance with AOP-019, Malfunction of RCS pressure Control, and/or AOP-025, RTGB Instrument Failure. RCS pressure control will remain in MANUAL for the remainder of the scenario. The operator will address Technical Specification LCO 3.3.4, Remote Shutdown System, Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, and Technical Specification LCO 3.4.11, Pressurizer Power Operated Relief Valves (PORVs).

After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur.

Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection.

Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The Scenario Event Description NRC Scenario 3 operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start.

The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

Critical Tasks:

Manually control B S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the B S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Manually close the OPEN Pzr Spray Valve(s) and the Block Valve for the Stuck Open PORV before the Reactor trips based on low pressurizer pressure.

Safety Significance: failure to close the Spray Valves/PORV Block Valve and stop the pressure transient, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection System. Performance of the critical task would stabilize the pressure transient. A failure to stabilize the pressure transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS pressure control.

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First (EOP-Based)

Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

Establish Feedwater Flow Into at Least One S/G Before RCS Bleed and Feed is Required (EOP-Based)

Safety Significance: Failure to establish feedwater flow to any SG results in the operators having to rely upon the lower-priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that fails to prevent degradation of any barrier to fission product release.

Description:

Inadvertent FWIS/ Turbine fails to Trip/GV Valves fail to Runback/MSI fails to AUTO Actuate/ A & B MDAFW Pump Trip After the Pressure Transmitter has been removed from service, an inadvertent FWIS will occur. Simultaneously with the Rx Trip, the Turbine will fail to TRIP, the Governor Valves will fail to CLOSE manually, and the Main Steamline Isolation signal will fail to auto actuate. The operator will be required to manually CLOSE the MSIVs. Additionally the A and B MDAFW Pumps will trip immediately after auto start. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. Upon completion of EOP-E-0, the operator will transition to EOP-ES-0.1, Reactor Trip Response. However, this transition will be delayed due to a RED condition on the Heat Sink CSF. The operator will perform FRP-H.1, Response to Loss of Secondary Heat Sink. The operator will direct that AFW Pump C be placed in service in accordance with OP-402, Auxiliary Feedwater System, however, the AFW Pump C Diesel will fail to start. The scenario will terminate at Step 7 RNO 2.b of FRP-H.1, after the operator has restored feedwater flow from the Main Feedwater System.

  • IF Turbine will NOT trip, THEN manually RUNBACK Turbine at maximum rate UNTIL ALL Governor valves are CLOSED.
  • IF Turbine can NOT be runback, THEN manually CLOSE MSIVs AND MSIV Bypass Valves.

BOP (Step 2.b) All MSR Purge AND Shutoff Valves - CLOSED Critical Task:

Manually Close the MSIVs Before an ORANGE Path Challenge Develops to Either the Subcriticality or the Integrity CSF or Before Transition to ECA-2.1, Whichever Happens First Safety Significance: Failure to trip the main turbine under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a failure by the operator to demonstrate the ability to take one or more actions that would prevent a challenge to plant safety. The situation described in the plant conditions is effectively a large steamline break downstream of the MSIVs. This effective steamline break is also located downstream of the main turbine stop valves, which cannot be closed by manually tripping the turbine. Failure to perform the critical task results in uncontrolled depressurization of all SGs and in uncontrolled cooldown of the RCS, both of which are unnecessary.

The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The A SI Pump is OOS. The B SI Pump has been aligned to 480 VAC ESF Bus E-1. PI-1616, SW North Header Pressure, is OOS (I&C Investigating). RTGB Annunciator APP-007-C3, FW PMP A LO FLOW TRIP, has failed to the EXTINGUISHED condition (I&C is investigating). The crew will be directed to raise power to 100%.

Shortly after taking the watch, the operator will attempt to raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS). During the first dilution, the A Primary Water Pump will trip. The operator will respond in accordance with APP-003-E5, MAKEUP WATER DEV, and/or AOP-003, Malfunction of Reactor makeup Control. The operator will place the B Primary Water Pump in service and continue with the startup.

After this, the operator will raise power to 100% using OP-105, Maneuvering the Plant When Greater than 25% Power, and OP-301, Chemical and Volume Control System (CVCS).

During the power increase Letdown Temperature Controller, TCV-144, will fail CLOSED causing letdown temperature to rise above 135°F. Simultaneously, Divert Valve TCV-143, will fail to divert letdown flow to the VCT. The operator will respond in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD, divert letdown flow to the VCT, take MANUAL control of TCV-144 to stabilize letdown temperature, and return letdown to the VCT.

Following this, Main Steam Line C Pressure Transmitter, PT-495, will fail LOW. The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will remove the failed instrument from service in accordance with OWP-025, Steam Generator Pressure (SGP). The operator will address Technical Specification LCO 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, and Technical Specification LCO 3.3.6, Containment Ventilation Isolation Instrumentation.

Next, Power Range, NI-44, Upper Detector will fail HIGH. The operator will remove the failed instrument from service in accordance with OWP-011, Nuclear Instrumentation (NI). The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS)

Instrumentation.

Shortly afterwards, an oil leak will develop on the Main Turbine. The operator will respond in accordance with various APP-008, SW, CW & TURB GEN AUX, alarms, and ultimately enter AOP-007, Turbine Trip Below P-8. When the Main Turbine Trips one Turbine Stop Valve and one Turbine Governor Valve will remain OPEN, and the operator will need to manually TRIP the Turbine.

Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Scenario Event Description NRC Scenario 4 Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST.

Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition.

The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Critical Tasks:

Manually control C S/G Narrow Range Level before a Reactor Trip occurs on low S/G level or a Protective Action occurs on high S/G Level.

Safety Significance: failure to take manual control of the C S/G Feed Reg Valve and control Narrow Range S/G level, under the postulated plant conditions, results in an unnecessary transient to the plant and challenge to the Reactor Protection/Engineered Safeguards Actuation System. Performance of the critical task would stabilize the S/G level transient. A failure to stabilize the S/G level transient, when able to do so, constitutes a mis-operation or incorrect crew performance which leads to incorrect RCS temperature/pressure control.

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF. Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of E-2 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs.

Stop the High Head SI Pumps Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Scenario Event Description NRC Scenario 4 Safety Significance: Failure to stop the high head SI Pumps results in challenges to the Integrity CSF; and could unnecessarily result in a mechanical failure due to Pressurized Thermal Shock.

Description:

ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Subsequently, the Control Power fuse for Power Range channel N41 will blow causing an automatic reactor trip signal to be generated, however, the reactor will fail to TRIP both automatically and manually (ATWS). The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and attempt to manually trip the reactor. When this fails, the operator will enter FRP-S.1, Response to Nuclear Power Generation- ATWS. While in FRP-S.1, Boric Acid to Charging Pump Suction Valve MOV-350 will fail CLOSED. The operator will direct a local trip of the reactor, drive rods in manually, and align the suction of the Charging Pumps to the RWST. Upon completion of FRP-S.1, a B Steam Line will rupture inside Containment (over 10 minutes), and the operator will re-enter EOP-E-0, Reactor Trip or Safety Injection. Ultimately, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, to isolate the flow into and out of the B Steam Generator and then terminate Safety Injection. However, an Orange and/or Red Path will exist on the RCS Critical Safety Function, and the operator will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition. The scenario will terminate at Step 12 of FRP-P.1, when the operator stops SI Pumps.

Description:

ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Time Pos. Expected Actions/Behavior Comments RO (Step 1) CHECK Reactor Trip: Immediate Action

  • Rod position indicators FULLY INSERTED
  • Rod Bottom Lights ILLUMINATED
  • Neutron flux - LOWERING RO (Step 1 RNO) PERFORM the following: Immediate Action
  • Manually TRIP Reactor.

Critical Task:

Insert Negative Reactivity into the Core by Inserting Control Rods Manually Prior to Locally Tripping the Reactor (EOP-Based)

Safety Significance: Failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor remains critical or returns to a critical condition. Performance of the critical task would make the reactor subcritical and provide sufficient shutdown margin to prevent (or at least minimize the power excursion associated with) any subsequent return to criticality. Failure to insert negative reactivity constitutes mis-operation or incorrect operator performance which fails to prevent incorrect reactivity control. In the scenario postulated by the plant conditions, failure to insert negative reactivity by inserting control rods can result in the needless continuation of an extreme or a severe challenge to the subcriticality CSF.

Although the challenge was not initiated by the operator (was not initiated by operator error), continuation of the challenge is a result of the operators failure to insert negative reactivity.

Description:

ATWS/MOV-350 fails to OPEN/B SG SLB Inside CV Time Pos. Expected Actions/Behavior Comments

  • IF ANY valve can NOT be closed, THEN Critical Task:

Isolate Feedwater Flow Into and Steam Flow From the Faulted S/G Before a Transition Out of FRP-P.1 Occurs (EOP-Based)

Safety Significance: Failure to isolate a faulted SG that can be isolated causes challenges to CSFs beyond those irreparably introduced by the postulated conditions.

Also, depending upon the plant conditions, it could constitute a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component. Failure to isolate a faulted SG can result in challenges to the Integrity, Subcriticality and Containment CSFs; and result in a mechanical failure due to Pressurized Thermal Shock.

The area has experienced steady light rain for the past 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with light wind from the South at 5-10 mph, and this is expected to continue throughout the shift.

The following equipment is Out-Of-Service: The B Condensate Pump is OOS. LI-1417A, Hotwell Level Indication is OOS (I&C Investigating). RTGB Annunciator APP-006-F7, PWST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 30%.

Shortly after taking the watch, the operator will raise power to 5-8% and startup the Turbine using GP-005, Power Operation.

When the Turbine is rolling, a HIGH Eccentricity condition will develop on the Main Turbine.

The operator will respond using AOP-006, Turbine Eccentricity/Vibration, and place the Turbine startup on HOLD.

Shortly afterwards, the compensating voltage on Intermediate Range Channel N-35 will fail.

The operator will remove the instrument from service using OWP-011, Nuclear Instrumentation (NI). The failed channel will require that the Source Range instruments be manually re-energized in the subsequent post-trip conditions. The operator will address Technical Specification LCO 3.3.1, Reactor Protection System (RPS) Instrumentation, and determine to continue with the power increase.

Following this, VCT Level Transmitter LT-112 will fail HIGH causing LCV-115A to divert all letdown flow to the CVCS HUTs and result in an automatic makeup to the VCT. The operator will respond in accordance with AOP-003, Malfunction of Reactor Makeup Control. After this, the power increase will continue.

Next, a Thermal barrier leak will develop on the B RCP and Flow Control Valve FCV-626 will fail to CLOSE. The operator will respond in accordance with APP-001-C1, RCP THERM BAR COOL WTR HI FLOW, and AOP-014, Component Cooling Water Malfunction. The operator will address Technical Specification LCO 3.6.1, Containment, and Technical Specification LCO 3.6.3, Containment Isolation Valves.

Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically.

The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor.

Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Uncontrolled Depressurization of All Steam Generators, and lower AFW flow to each Steam Generator to 60 gpm.

While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure is expected to rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2.

Scenario Event Description NRC Scenario 5 The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators. Depending on the timing of the actions taken by the crew when the A MSIV is closed, the A S/G pressure may not rise significantly higher than that of the B and C S/Gs, and the crew will remain in EOP-ECA-2.1 past the SI termination steps (i.e. Step 19). If this situation occurs, the scenario will terminate at Step 20 of EOP-ECA-2.1.

Critical Tasks:

Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions. Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Description:

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Subsequently, a Steam Rupture will occur downstream of the MSIVs and the MSIVs will fail to CLOSE automatically and manually. Simultaneously, the Reactor will fail to TRIP automatically. The operator will enter EOP-E-0, Reactor Trip or Safety Injection, and manually trip the reactor. Upon completion of EOP-E-0, the operator will transition to EOP-E-2, Faulted Steam Generator Isolation, and then when it is realized that all Steam Generators are faulted, transition to EOP-ECA-2.1, Loss of Reactor or Secondary Coolant, and lower AFW flow to each Steam Generator to 60 gpm. While terminating Safety Injection in EOP-ECA-2.1, the A MSIV will close and the A S/G pressure will rise higher than that of the B and C S/Gs. Since the crew will be in the process of terminating SI in EOP-ECA-2.1, the crew will continue to complete the SI termination steps before transitioning back to EOP-E-2. The scenario will terminate at Step 4.c of EOP-E-2, after the operator has closed the AFW Discharge valves to the B and C Steam Generators.

Description:

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos. Expected Actions/Behavior Comments Critical Task:

Manually trip the reactor from the control room before entry into FRP-S.1 Safety Significance: Failure to manually trip the reactor causes a challenge to the subcriticality CSF beyond that irreparably introduced by the postulated conditions.

Additionally, it constitutes an incorrect performance that necessitates the operator taking compensating action that would complicate the event mitigation strategy and demonstrates the inability of the operator to recognize a failure or an incorrect automatic actuation of an ESF system or component. The ERG Background Document for E-0 states that one function of E-0 is to verify that all required automatic protective actions occur before transitioning the crew to the appropriate ORG. The verification is important because the subsequent ORGs are based on the assumption that protective systems will protect all CSFs while the ORG is implemented. Not tripping the reactor when it is possible to do so (as in the postulated conditions) forces an immediate extreme challenge to the subcriticality CSF. Additionally, the incorrect performance of failing to trip the reactor necessitates the operator taking compensating action that seriously complicates the event mitigation strategy. This mis-operation constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

Description:

Steam Rupture downstream of the MSIVs w/failure of the MSIVs to CLOSE/ Failure of Automatic Rx Trip Time Pos. Expected Actions/Behavior Comments Critical Task:

Control the AFW flow rate to not less than 60 gpm per SG in order to minimize the RCS cooldown rate before an EXTREME (Red Path) challenge develops to the RCS Integrity CSF Safety Significance: Failure to control the AFW flow rate to the SGs leads to an unnecessary and avoidable extreme challenge to the integrity CSF. Also, failure to perform the critical task increases the challenges to the subcriticality CSF beyond which is irreparably introduced by the postulated plant conditions. Thus, failure to perform the critical task constitutes a demonstrated inability by the operator to take one or more actions that would prevent a challenge to plant safety. It also fails to prevent a significant reduction of safety margin beyond that irreparably introduced by the scenario.

RTGB Annunciator APP-002-F8, STA AIR HDR LO PRESS, has failed to the ILLUMINATED condition (I&C is investigating). The B MFWP has experienced high noise/vibration over the last two hours (Maintenance is investigating).

Shortly after taking the watch, HCV-1459, Heater Bypass Valve will fail OPEN. The crew will implement AOP-010, Main Feedwater/Condensate Malfunction, and close the valve.

After the overpower transient is stabilized, the WCCS will call the control room and direct that reactor power be lowered to 50% for the purpose of removing the B Main Feedwater Pump from service. The operator will lower power in accordance with AOP-038, Rapid Downpower.

After the power reduction is in progress, the C Service Water Pump will trip on overload. This will cause the running Service Water Booster Pump to trip as well. The operator will respond in accordance with various APP-008 annunciators and start a standby Service Water Pump; and then respond in accordance with APP-002-A through D8, HVH WTR OUTLET LO FLOW, and re-start a Service Water Booster Pump. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), and Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems.

Following this, Breaker 52/32A will Trip de-energizing the DS Bus, and stopping the only running Charging Pump and CCW Pump. The operator may address AOP-018, Reactor Coolant Pump Abnormal Conditions, or various APPs to restore Charging and Seal Injection flow; and then APP-001-F5, CCW PMP LO PRESS, and ensure that the standby CCW Pump started. 10 seconds after the Standby CCW Pumps start, the C CCW Pump will trip, and only the B CCW will be left running. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System, and Technical Specification LCO 3.4.17, Chemical and Volume Control System (CVCS).

Next, a #1 Seal Failure will occur on the A RCP. The crew will implement AOP-018, Reactor Coolant Pump Abnormal Conditions, trip the reactor, stop the pump, and three minutes after the pump is stopped, CLOSE the Seal Leakoff Valve. The crew will enter EOP-E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur on the reactor trip, and the B Emergency Diesel Generator will fail to automatically start. Additionally, the DS DG will trip.

Upon entry into EOP-E-0, the operator will determine that both ESF buses are de-energized and transition to EOP-ECA-0.0, Loss of All AC Power. The operator will subsequently start the B EDG by depressing the SI Actuate Pushbutton, restore power to Bus E-2, and transition back to EOP-E-0. When Bus E-2 is re-energized, the D Service Water Pump will fail to sequence automatically and will need to be manually started.

Upon transition back to EOP-E-0, the crew will complete the immediate actions of EOP-E-0, and continue with AOP-018.

Scenario Event Description NRC Scenario 6 The scenario will terminate when the crew has terminated Safety Injection and re-established Charging/Seal Injection in Step 6 of ES-1.1.

Critical Tasks:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals.

Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.

Description:

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos. Expected Actions/Behavior Comments Critical Task:

Energize at Least One AC Emergency Bus Before Defeating the Auto Loading of the Safeguards Equipment in EOP-ECA-0.0 Safety Significance: Failure to energize an ac emergency bus constitutes mis-operation or incorrect crew performance in which the crew does not prevent degraded emergency power capacity. Failure to perform the critical task also results in needless degradation of any barrier to fission product release, specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to perform the critical task results in the unnecessary continuation of a situation in which RCS inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to mis-operation or incorrect operator performance in which the operator does not prevent degraded emergency core cooling system (ECCS) capacity at a time when a small-break LOCA is in progress. In this case, at least one ac emergency bus can be energized from the control room. Failure to perform the critical task means that RCS inventory lost through the RCP seals cannot be replaced. It also means that the RCP seals remain without cooling and gradually deteriorate. As the seals deteriorate the rate of RCS inventory loss increases.

  • Establish Seal Injection flow
  • CHECK adequate DSDG OR EDG capacity to run one Charging Pump (108 KW each) (DSDG preferred)

Description:

Loss of Offsite Power/B EDG Fails to Start/DSDG Trips/D Service Water Pump fails to Auto Start Time Pos. Expected Actions/Behavior Comments Critical Task:

Manually Start SW Pump for EDG Cooling within 40 Minutes of starting the B EDG Safety Significance: Failure to manually start the SW pump under the postulated plant conditions means that the EDG is running without SW cooling. Running the EDG without SW cooling leads to a high-temperature condition that can result in EDG failure due to damage caused by engine overheating. Under the postulated plant conditions, the running EDG is the only operable EDG. The calculated maximum time an EDG may operate without cooling to preclude adverse effects is 40 minutes. Since during the first 40 minutes of EDG operation in this scenario there are two procedural cues to check, and if needed, start a SW Pump, it is believed that failure to perform the critical task constitutes mis-operation or incorrect performance in which the crew does not prevent degraded emergency power capacity.
