Scenario Event Description NRC Scenario 1 H B Robinson 2016-2RT NRC Scenario #1 The plant is at 37% power (BOL). The area has experienced steady light rain for the past 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, with light wind from the West 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. ACTION has been taken in accordance with Technical Specification LCO 3.5.2 ACTION A. TI-471, PRT Temperature is OOS (I&C investigating). RTGB Annunciator APP-010-D8, RHR PIT A HI TEMP, has failed to the ILLUMINATED condition (I&C is investigating). The crew will be directed to raise power to 100%.
Upon taking the watch, the operator will raise power to 100% using GP-005, Power Operation, and OP-301, Chemical and Volume Control System (CVCS).
Following this, the Pressurizer Pressure Controller, PC-444J will experience a control band shift (controller will act to control pressure at 1950 psig). The operator will respond in accordance with AOP-019, Malfunction of RCS Pressure Control to take manual control of the Pressure Controller and restore RCS pressure to the normal control band. The operator will address Technical Specification LCO 3.4.1, RCS Pressure, Temperature and Flow Departure from Nucleate Boiling (DNB) Limits.
Next, the South Service Water Header will experience a break at the intake structure on the SW piping downstream of SW-5, SW Pump A Discharge Tee. The operator will respond in accordance with AOP-022, Loss of Service Water, to realign the Service Water System and isolate the leak. The operator will address Technical Specification LCO 3.7.7, Service Water System (SWS), Technical Specification LCO 3.6.6, Containment Spray and Cooling Systems, and LCO 3.8.1, AC Sources - Operating. The A EDG will be declared inoperable. Station Management will directed that power be held at the current power until further direction.
After this, a 35 gpm RCS leak will occur in the Containment. The operator will respond in accordance with AOP-016, Excessive Primary Plant Leakage. The operator will address Technical Specification LCO 3.4.13, Operational leakage.
The RCS leakage will degrade to the point where a Reactor trip will be required. The Reactor will fail to TRIP manually from the RTGB (also automatic trips are failed) (ATWS). The operator will enter EOP-E-0, Reactor Trip and 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 The operator will direct a local trip of the reactor, drive rods in manually, and direct emergency boration of the RCS.
The RCS leakage will evolve into a Cold Leg Small Break LOCA (over a total of 10 minutes) on the C Loop. Simultaneously, Phase A Containment Isolation will fail to actuate automatically, and the operator will need to manually actuate Phase A Containment Isolation. Upon completion of FRP-S.1 the operator will transition back to EOP-E-0.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant. Upon the transition to EOP-E-1, a loss of Emergency Bus E2 will occur due to the Normal Supply breaker, 52/28B tripping open. The operator will be required to manually re-start ECCS equipment.
Scenario Event Description NRC Scenario 1 The scenario will terminate at Step 11 of EOP-E-1, after the operator has determined that ECCS flow cannot be terminated.
Critical Tasks:
Manually control PC-444J and close the PZR Spray valves before the plant trips on OTT.
Safety Significance: failure to close the Spray 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.
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 (Rods are in manual for the power ascension),
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.
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)
NOTE: This may not be a valid critical task if subcooling does NOT reach 13°F. Observe RCS subcooling closely, as it closely approaches this setpoint.
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.
Close containment isolation valves such that at least one valve is closed on each critical Phase A penetration within 20 minutes of the Phase A isolation signal (EOP Based)
Safety Significance: Closing at least one containment isolation valve on each critical. Phase A penetration, under the postulated plant conditions and when it is possible to do so, constitutes a task that is essential to safety, because its improper performance or omission by an operator will result in direct adverse consequences or significant degradation in the mitigative capability
Scenario Event Description NRC Scenario 1 of the plant. In particular, the operator has failed to prevent degradation of any barrier to fission product release. In this case, the containment barrier is needlessly left in a degraded condition.
Failure to perform the critical task leads to an unnecessary release of fission products to the auxiliary building, increasing the potential for release to the environment and reducing accessibility to vital equipment within the auxiliary building. High radiation in the auxiliary building can lead to increased doses to personnel. Failure to perform the critical task also constitutes a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component.
Establish flow from at least one high-head SI pump after power is restored to the ESF Bus in E-1. (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.

Description:
ATWS/ SBLOCA RCS Cold Leg C/ PHASE A CI fails to AUTO INITIATE/ Loss of Emergency Bus E-2 Normal power The RCS leakage will degrade to the point where a Reactor trip will be required. The Reactor will fail to TRIP manually from the RTGB (also automatic trips are failed)
(ATWS). The operator will enter EOP-E-0, Reactor Trip and 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 The operator will direct a local trip of the reactor, drive rods in manually, and direct emergency boration of the RCS. The RCS leakage will evolve into a Cold Leg Small Break LOCA (over a total of 10 minutes) on the C Loop. Simultaneously, Phase A Containment Isolation will fail to actuate automatically, and the operator will need to manually actuate Phase A Containment Isolation. Upon completion of FRP-S.1 the operator will transition back to EOP-E-0.
Upon completion of EOP-E-0, the operator will transition to EOP-E-1, Loss of Reactor or Secondary Coolant. After the crew has reset SI, a loss of Emergency Bus E2 will occur due to the Normal Supply breaker, 52/28B tripping open. The operator will be required to manually re-start ECCS equipment.
The scenario will terminate at Step 11 of EOP-E-1, after the operator has determined that ECCS flow cannot be terminated.

Description:
ATWS/ SBLOCA RCS Cold Leg C/ PHASE A CI fails to AUTO INITIATE/ Loss of Emergency Bus E-2 Normal power Time Pos. Expected Actions/Behavior Comments 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 (Rods are in manual for the power ascension), 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.
BOP DISPATCH operator to locally open the NOTE: The CRS will dispatch following breakers: both the Inside and Outside AO.

CHECK Containment Isolation Phase A NOTE: Containment Isolation ACTUATED Phase A has NOT actuated.
BOP (Step 4.a RNO) Manually ACTUATE BOTH NOTE: If NOT done already, trains of Containment Isolation Phase A. the BOP will manually actuate Containment Isolation Phase A.
Critical Task:
Close containment isolation valves such that at least one valve is closed on each critical Phase A penetration within 20 minutes of the Phase A isolation signal (EOP Based)
Safety Significance: Closing at least one containment isolation valve on each critical.
Phase A penetration, under the postulated plant conditions and when it is possible to do so, constitutes a task that is essential to safety, because its improper performance or omission by an operator will result in direct adverse consequences or significant degradation in the mitigative capability of the plant. In particular, the operator has failed to prevent degradation of any barrier to fission product release. In this case, the containment barrier is needlessly left in a degraded condition. Failure to perform the critical task leads to an unnecessary release of fission products to the auxiliary building, increasing the potential for release to the environment and reducing accessibility to vital equipment within the auxiliary building. High radiation in the auxiliary building can lead to increased doses to personnel. Failure to perform the critical task also constitutes a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component.

Description:
ATWS/ SBLOCA RCS Cold Leg C/ PHASE A CI fails to AUTO INITIATE/ Loss of Emergency Bus E-2 Normal power Time Pos. Expected Actions/Behavior Comments Critical Task:
Close containment isolation valves such that at least one valve is closed on each critical Phase A penetration within 20 minutes of the Phase A isolation signal (EOP Based)
Safety Significance: Closing at least one containment isolation valve on each critical.
Phase A penetration, under the postulated plant conditions and when it is possible to do so, constitutes a task that is essential to safety, because its improper performance or omission by an operator will result in direct adverse consequences or significant degradation in the mitigative capability of the plant. In particular, the operator has failed to prevent degradation of any barrier to fission product release. In this case, the containment barrier is needlessly left in a degraded condition. Failure to perform the critical task leads to an unnecessary release of fission products to the auxiliary building, increasing the potential for release to the environment and reducing accessibility to vital equipment within the auxiliary building. High radiation in the auxiliary building can lead to increased doses to personnel. Failure to perform the critical task also constitutes a failure by the operator to demonstrate the ability to recognize a failure or an incorrect automatic actuation of an ESF system or component.

Depending on the timing of mitigation actions, the RCP trip criteria may or may not be met.
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. EXAMINER NOTE: The booth operator will be closely monitoring RCS Subcooling. Subcooling very closely approaches 13°F, but if the value is not exceeded, this critical task is NOT valid.
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 after power is restored to the ESF Bus in E-1. (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 H B Robinson 2016-2RT NRC Scenario #2 The plant is at 100% power (MOL). The area has experienced steady light rain for the past 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, with light wind from the West 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 since the last shift. Maintenance reports that this pump will be OPERABLE within this shift. LI-924, B SI Accumulator Level, is OOS (I&C Investigating). RTGB Annunciator APP-006-E7, CST HI/LO LVL, has failed to the ILLUMINATED condition (I&C is investigating).
Shortly after taking the watch, Turbine 1st Stage Pressure Transmitter PT-447 will fail LOW.
The operator will respond in accordance with AOP-025, RTGB Instrument Failure. The operator will restore all Steam Generators to the programmed level with Feed Reg 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, a 5 gpm Steam Generator Tube Leak will develop in the A Steam Generator.
The operator will respond in accordance with AOP-005, Radiation Monitoring System, AOP-016, Excessive Primary Plant Leakage and/or AOP-035, S/G Tube Leak. The operator will initiate a load reduction in accordance with AOP-038, Rapid Downpower. The operator will address Technical Specification LCO 3.4.13, RCS Operational Leakage.
During the downpower, T-ref will fail LOW. The operator will respond in accordance with AOP-001, Malfunction of Reactor Control System.
Subsequently, the Steam Generator Tube Leak will degrade rapidly to a Rupture (in 1 minute).
Additionally, upon either the automatic or manual Safety Injection, the A SI Pump will fail to automatically start and the operator will be required to manually start this pump. Furthermore, both SI-870A & SI-870B (BIT OUTLET valves) will fail to open automatically on SI, and the operator will be required to manually open these valves. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. 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 A Steam Generator and then conduct a cooldown of the RCS.
The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.
Critical Tasks:
Establish flow from at least one high-head SI pump before RCS pressure lowers to less than the shutoff head of the pump (1500 PSIG as read on PT-511BA, RVLIS RCS WR PRESS). (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
Scenario Event Description NRC Scenario 2 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.
Isolate feedwater flow into and steam flow from the ruptured SG within 30 minutes and before ruptured SG Pressure lowers below 500 PSIG, requiring a transition ECA-3.1 (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes an increased release of radioactivity from the affect SG to the environment. Accident analysis in UFSAR 15.6.3.2.1 assume that for the SGTR the affected SG is isolated within 30 minutes. AP-025, Operator Time Critical Action Program, further identifies that this is a 30 minute time requirement.
Additionally the 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 (If above 100% WR level see Simulator Variable THLECELL 191 to determine). (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.

Description:
A SGTR/ A SI Pump Fails to AUTO Start/ SI-870A & SI-870B Fail to AUTO OPEN Subsequently, the Steam Generator Tube Leak will degrade rapidly to a Rupture (in 1 minute). The operator will recognize the degrading conditions and the need for a Reactor Trip and Safety Injection. Additionally, upon either the automatic or manual Safety Injection, the A SI Pump will fail to automatically start and the operator will be required to manually start this pump. Furthermore, both SI-870A & SI-870B (BIT OUTLET valves) will fail to open automatically on SI, and the operator will be required to manually open these valves. The operator will enter EOP-E-0, Reactor Trip or Safety Injection. 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 A Steam Generator and then conduct a cooldown of the RCS. The scenario will terminate at Step 23 of EOP-E-3, after the operator has stopped the SI Pumps.

Description:
A SGTR/ A SI Pump Fails to AUTO Start/ SI-870A & SI-870B Fail to AUTO OPEN Time Pos. Expected Actions/Behavior Comments Critical Task:
Establish flow from at least one high-head SI pump before RCS pressure lowers to less than the shutoff head of the pump (1500 PSIG as read on PT-511BA, RVLIS RCS WR PRESS). (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.

Description:
A SGTR/ A SI Pump Fails to AUTO Start/ SI-870A & SI-870B Fail to AUTO OPEN Time Pos. Expected Actions/Behavior Comments Critical Task:
Isolate feedwater flow into and steam flow from the ruptured SG within 30 minutes and before ruptured SG Pressure lowers below 500 PSIG, requiring a transition ECA-3.1 (EOP-Based)
Safety Significance: Failure to isolate the ruptured SG causes an increased release of radioactivity from the affect SG to the environment. Accident analysis in UFSAR 15.6.3.2.1 assume that for the SGTR the affected SG is isolated within 30 minutes. AP-025, Operator Time Critical Action Program, further identifies that this is a 30 minute time requirement. Additionally the 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.

Description:
A SGTR/ A SI Pump Fails to AUTO Start/ SI-870A & SI-870B Fail to AUTO OPEN Time Pos. Expected Actions/Behavior Comments 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°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.

Description:
A SGTR/ A SI Pump Fails to AUTO Start/ SI-870A & SI-870B Fail to AUTO OPEN Time Pos. Expected Actions/Behavior Comments 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 Variable THLECELL 191 to determine). (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.
At the discretion of the Lead Examiner terminate the exam.
