McGuire 2011 NRC Scenario #1 The plant is at 75% power (MOL), and has been at this power level for 4 days. The crew is expected to raise power to 100% on this shift.

The following equipment is Out-Of-Service: 1 B KG Pump is OOS for motor replacement. 1NIP-5070, ACCUM TK lB PRESS, failed last shift (IAE is investigating) and MCB Annunciator 1AD-2, D-5, LOSS OF SUBCOOLING, has alarmed spuriously several times over the last hour, however, level has indicated normal (IAE is investigating).

Shortly after taking the watch, the operator will commence a load increase to 100%

starting with Step 3.32 of Enclosure 4.1, Power Increase, of OP/i/A/6100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with Enclosure 4.4, Alternate Dilute, of OP/1/A161 50/009, Boron Concentration Control, and raise Turbine load in accordance with OP/i /A/6300/001 A, Turbine-Generator Load Change.

During the power increase, the I D Steam Generator PORV will develop a leak through the seat. The operator will respond in accordance with AP/1/A15500/01, Steam Leak, and isolate the PORV. The operator will address Technical Specification 3.7.4, Steam Generator Power Operated Relief Valves (SG PORVs), and will determine that all SG PORVs are OPERABLE.

Next, a B Train PORV (1NC-32B) will fail slightly open. The operator will enter AP/1/A15500/1 1, Pressurizer Pressure Anomalies. The operator will address Technical Specification 3.4.1 i, Pressurizer Power Operated Relief Valve (PORVs), and may enter 3.4.1, RCS Pressure, Temperature and Flow Departure from Nucleate Boiling (DNB) Limits.

Subsequently, a Zone lB Lockout causes PCB ii and 12 to open, as well as the lB Main Generator Breaker to open and the turbine to automatically runback to 56%. The operator will implement AP/1/A15500/03, Load Rejection. During the runback the operator will notice that the rods do not move in auto, and the operator will need to drive rods in manually.

Following this, Train A Safety Injection will spuriously actuate. The Reactor will fail to trip automatically and the operator will need to trip the Reactor manually. The operator will enter EP/1/A15000/E-0, Reactor Trip or Safety Injection, and then transition to step 10 of EP/1/A/5000/ES-i .1, Safety Injection Termination.

Upon entry into EP/1/A15000/ES-i.1, the operator will stop NI and ND pumps.

The scenario will terminate in EP/1/A/5000/ES-1.1 at Step 12 when the operator determines that Safety Injection is NOT required.

Critical Tasks:

E-OA Manually trip the reactor prior to transition to FR-S.1, Response to Nuclear GenerationlATWS.

Safety Significance: Failure to trip the reactor when required causes a challenge to the Subcriticality Critical Safety Function that otherwise would not exist. This mis-operation by the operator necessitates the crew taking compensating action which complicates the event mitigation strategy and demonstrates an inability by the operator to recognize a failure of the automatic actuation of the RPS.

SS (4600!1131E13.6)

Terminate SI by closing Nl-9110 within 15 minutes of SI actuation.

Safety Significance: An inadvertent SI rapidly injects inventory into the NCS causing Pzr Level, and correspondingly, Pzr Pressure to increase. Prolonged recovery unnecessarily challenges the Pzr Code Safety valves. PTIOIAI4600II 13, Enclosure 13.6 states that when at NOP/NOT conditions, the FSAR commitment is to have SI terminated within 15 minutes (The Safety Analysis CANNOT credit the cycling of the Pzr PORVs since auto PORV operation can only be assured during LTOP Operation). The Safety Analysis assumes that the Pzr Code Safeties will lift and reseat ONLY if they are cycled for a short time and Pzr liquid temperature remains >

500°F. If this action is not taken, the conclusions of the Safety Analysis are invalid, and violates a License Condition.

McGuire 2011 NRC Scenario #2 The plant is at 100% power (MOL), and has been at this power level for 250 days.

The following equipment is Out-Of-Service: 1A DG is OOS for corrective maintenance.

1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-9, D-4, D COLD LEG ACCUMULATOR ABNORMAL LEVEL, has failed to off (AE is investigating).

Shortly after taking the watch, the High Pressure Heater Bypass Valve (ICF-75) will inadvertently open. The operator will respond in accordance with OAC Alarm Response Procedure M1L2917, Ui WATER BYPASSING A&B HEATERS, and the Control Room Expectation Manual, and immediately reduce Turbine load as needed to maintain Rx power less than pre-transient condition.

After this, Power Range Instrument N42 will drift high. The operator will enter AP111A15500116, Malfunction of Nuclear Instrumentation. The operator will address Technical Specification 3.3.1, Reactor Trip System (RTS) Instrumentation.

Next, the 1 B2 KC Pump will trip. The operator will enter AP/1/A15500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification 3.7.6, Component Cooling Water (CCW) System.

Subsequently, the lB DG will be declared inoperable. The crew will be directed to reduce plant power to Mode 3 within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The operator will perform a rapid downpower in accordance with AP/1/A/5500/04, Rapid Downpower.

During the downpower, the Control Rods will continuously insert. The operator will enter AP/1/A15500/14, Rod Control Malfunction, and take manual control of the rods.

Following this, the Turbine will inadvertently trip, and the Reactor will fail to trip automatically and manually. Additionally, one Safety Valve on the 1 B Steam Generator will lift and fail Open. The operator will enter EP/1/A15000/E-0, Reactor Trip or Safety Injection, and then transition to EP/1/A15000/FR-S.1, Response to Nuclear Power Generation/ATWS. During the performance of FR-Si, the operator will successfully trip the Reactor.

On the Reactor trip, the TD CA will trip on overspeed, and the lA/lB MD CA Pump will fail to start automatically. The operator will be expected to manually start the MD CA Pumps.

After completion of FR-S.1, the operator will transition back to E-0, and then to EP/i/A/5000/E-2, Faulted Steam Generator Isolation. After the lB Steam Generator is isolated, the operator will transition to EP/i/A15000/ES-i.1, SI Termination.

The scenario will terminate at Step 7.c of ES-li.

Appendix D Scenario Outline Form ES-D-1 Draft (Rev_041111-) -

Critical Tasks:

FR-S.1 C Manually drive rods inward before completing the immediate actions of FR-S.1 (Step 2).

Safety Significance: failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor power remains higher than it otherwise would if the action is not taken. Performance of the critical task would move the reactor power lower to prevent a subsequent an unnecessary challenge to reactor core operational limits. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

E-0 F Establish 450 gpm of CA Flow to the Steam Generators before transition out of FR-S.1, unless the transition is made to EPIIIAI5000IFR-H.1, and then before the NCPs are manually tripped to limit heat input to the RCS.

Safety Significance: Failure to establish a Secondary Heat Sink through the initiation of CA flow unnecessarily challenges both the HEAT SINK and the CORE COOLING Critical Safety Functions. Additionally, the FSAR Safety Analysis results are predicated on the assumption that at least one train of safeguards actuates and delivers a minimum amount of AFW flow to the Steam Generators. Failure to perform this task, when the ability to do so exists, results in a violation of the Facility License Condition and places the plant in an unanalyzed condition.

McGuire 2011 NRC Scenario #3 Unit 1 is at lx10 amps in accordance with 0P111A161001003, Controlling Procedure for Unit Operation, Enclosure 4.1, Power Increase. It is intended to raise power on this shift. The CF&E Sump level is high, and the crew will need to pump the contents of the sump to the Floor Drains Tank.

The following equipment is Out-Of-Service: IA KR Pump is OOS for motor replacement.

1CAP-5610, CAST LEVEL CH 1, failed last shift (IAE is investigating). MCB Annunciator 1AD-4, A-5, BB BLOWOFF TANK LO LEVEL, has been in constant alarm over the last hour (IAE is investigating).

Upon shift turnover, before the operator initiates the power increase, the operator will pump the Containment Floor and Equipment (CF&E) Sump in accordance with Section 3.3 of Enclosure 4.2, Containment Floor and Equipment Sump and Incore Instrument Room Sump Operation, of OP/1/A/6500/001, Liquid Waste System.

Following this, the operator will raise power in accordance with Step 3.15 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation.

After this, the Compensating Voltage for Intermediate Range Channel N35 will fail. The operator will enter APII/A15500116, Malfunction of Nuclear Instrumentation, and perform Case II, Intermediate Range Malfunction The operator will address Technical Specification 3.3.1, Reactor Trip Instrumentation.

Subsequently, a leak will develop in the KC System. The operator will enter AP/1/A15500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification 3.7.6, Component Cooling Water System.

Next, one Control Bank D Control Rod will drop into the core. The operator will respond in accordance with ARP1AD-2/D-9, RPI at Bottom Rod Drop and will implement AP/1/A15500/14, Rod Control Malfunction. 30 seconds later a second Control Rod will drop requiring that the operator manually trip the reactor. The crew will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection. The operator will transition to EP/1 /A/5000/ES-0. 1, Reactor Trip Response.

Shortly after entry into EP/1/A/5000/ES-0.1, the O.B.E. Exceeded annunciator will alarm, indicating that an earthquake has occurred. Within seconds a large Steam Rupture will occur outside Containment on the A Steam Generator. The operator will actuate Safety Injection, and return to EP/1/A15000/E-0, Reactor Trip or Safety Injection.

Simultaneously, a Loss of Offsite Power will occur. Both Emergency Diesel Generators will start and load onto the Emergency Busses, and all SI loads will sequence on as designed.

Upon completion of E-0, the operator will transition to EP/1/A15000/E-2, Faulted Steam Generator Isolation. Upon completion of E-2, the operator will transition to either EP/1/A15000/E-1, Response to Loss of Primary or Secondary Coolant, or EP/1/A15000/ES-1 .1, SI Termination.

The scenario will terminate this transition is made.

Appendix D Scenario Outline Form ES-D-1 Draft (Re41111) - -

Critical Tasks:

ss Trip the reactor within 30 seconds of the second dropped rod (460011131E13.19)

Safety Significance: Multiple dropped control rods are a significant reactivity transient that can have a serious effect on plant parameters under certain operating conditions, and may result in power distribution limits being exceeded. The guidance to trip the reactor is a conservative action to prevent the plant from challenging the Pzr low pressure trip setpoint, etc.; and is consistent with the conservative nature of the industry. PT/0/A/4600/113, Enclosure 13.19 states that it is a management expectation that the operator trip the reactor within 30 seconds of a second dropped rod.

E-2A Isolate the Faulted Steam Generator before transitioning out of E-2.

Safety Significance: Failure to isolate a Faulted SG that can be isolated causes challenges to the Critical Safety Functions that would not otherwise occur. Failure to isolate flow could result in an unwarranted Orange or Red Path condition on NC Integrity and/or Subcriticality (if cooldown is allowed to continue uncontrollably).

NOTE: This scenario will require the assignment of a Surrogate Licensed Operator to monitor/control Steam Generator level, Steam Dumps, Tavg, Tcold and the operating CF Pump during this scenario. This is based on Step 3t2 of Enclosure 4.8 of OPIIIAI6IOO/003 which requires the assignment of this operator during reactor startup.

Shortly after taking the watch, the operator will commence a load increase to 100% starting with Step 3.32 of Enclosure 4.1, Power Increase, of OP/1/A16100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with .4, Alternate Dilute, of OP/1/A16150/009, Boron Concentration Control, and raise Turbine load in accordance with OP/1/A6300/001 A, Turbine-Generator Load Change.

During the power increase, the I D Steam Generator PORV will develop a leak through the seat.

The operator will respond in accordance with AP/1/A15500/01, Steam Leak, and isolate the PORV. The operator will address Technical Specification 3.7.4, Steam Generator Power Operated Relief Valves (SG PORVs), and will determine that all SG PORVs are OPERABLE.

Next, a B Train PORV (1NC-32B) will fail slightly open. The operator will enter AP/1/A/5500/11, Pressurizer Pressure Anomalies. The operator will address Technical Specification 3.4.11, Pressurizer Power Operated Relief Valve (PORV5), and may enter 3.4.1, RCS Pressure, Temperature and Flow Departure from Nucleate Boiling (DNB) Limits.

Subsequently, a Zone lB Lockout causes PCB 11 and 12 to open, as well as the lB Main Generator Breaker to open and the turbine to automatically runback to 56%. The operator will implement AP/1/A15500/03, Load Rejection. During the runback the operator will notice that the rods do not move in auto, and the operator will need to drive rods in manually.

Following this, Train A Safety Injection will spuriously actuate. The Reactor will fail to trip automatically and the operator will need to trip the Reactor manually. The operator will enter EP/1/A15000/E-0, Reactor Trip or Safety Injection, and then transition to step 10 of EP/1 /ASOOO/ES- 1.1, Safety Injection Termination.

Upon entry into EP/1/A15000/ES-1.1, the operator will stop NI and ND pumps.

The scenario will terminate in EP/l/A15000/ES-1 .1 at Step 12 when the operator determines that Safety Injection is NOT required.

CRITICAL TASK:

(SS-460011 I 31E1 3.6)

Terminate SI by closing NI-9110 within 15 minutes of SI actuation.

Safety Significance: An inadvertent SI rapidly injects inventory into the NCS causing Pzr Level, and correspondingly, Pzr Pressure to increase. Prolonged recovery unnecessarily challenges the Pzr Code Safety valves. PT/0/A14600/1 13, Enclosure 13.6 states that when at NOP/NOT conditions, the FSAR commitment is to have SI terminated within 15 minutes (The Safety Analysis CANNOT credit the cycling of the Pzr PORVs since auto PORV operation can only be assured during LTOP Operation). The Safety Analysis assumes that the Pzr Code Safeties will lift and reseat ONLY if they are cycled for a short time and Pzr liquid temperature remains>

500°F. If this action is not taken, the conclusions of the Safety Analysis are invalid, and violates a License Condition.

The following equipment is Out-Of-Service: 1A DG is OOS for corrective maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-9, D-4, D COLD LEG ACCUMULATOR ABNORMAL LEVEL, has failed to off (IAE is investigating).

Shortly after taking the watch, the High Pressure Heater Bypass Valve (1CF-75) will inadvertently open. The operator will respond in accordance with OAC Alarm Response Procedure M1L2917, Ui WATER BYPASSING A&B HEATERS, and the Control Room Expectation Manual, and immediately reduce Turbine load as needed to maintain Rx power less than pre-transient condition.

After this, Power Range Instrument N42 will drift high. The operator will enter AP/1/A15500/16, Malfunction of Nuclear Instrumentation. The operator will address Technical Specification 3.3.1, Reactor Trip System (RTS) instrumentation.

Next, the 1B2 KC Pump will trip. The operator will enter AP/1/A15500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification 3.7.6, Component Cooling Water (CCW) System.

Subsequently, the I B DG will be declared inoperable. The crew will be directed to reduce plant power to Mode 3 within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The operator will perform a rapid downpower in accordance with API1/A15500104, Rapid Downpower.

During the downpower, the Control Rods will continuously insert. The operator will enter AP111A15500114, Rod Control Malfunction, and take manual control of the rods.

Following this, the Turbine will inadvertently trip, and the Reactor will fail to trip automatically and manually. Additionally, one Safety Valve on the 1 B Steam Generator will lift and fail Open.

The operator will enter EP/1IAI5000IE-0, Reactor Trip or Safety Injection, and then transition to EPI1IAI5000IFR-S.1, Response to Nuclear Power Generation/ATVVS. During the performance of FR-S.1, the operator will successfully trip the Reactor.

On the Reactor trip, the TD CA will trip on overspeed, and the IA/I B MD CA Pump will fail to start automatically. The operator will be expected to manually start the MD CA Pumps.

After completion of FR-Si, the operator will transition back to E-0, and then to EPI1IA/50001E-2, Faulted Steam Generator Isolation. After the I B Steam Generator is isolated, the operator will transition to EPI1IAI5000IES-1.1, SI Termination.

The scenario will terminate at Step 7.c of ES-i.1.

Scenario Event Description fs1RCSeriO2 Critical Tasks:

FR-S.1 C Manually drive rods inward before completing the immediate actions of FR-S.1 (Step 2).

Safety Significance: failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor power remains higher than it otherwise would if the action is not taken. Performance of the critical task would move the reactor power lower to prevent a subsequent an unnecessary challenge to reactor core operational limits. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

E-0 F Establish 450 gpm of CA Flow to the Steam Generators before transition out of FR-S.1, unless the transition is made to EPIIIAI5000IFR-H.1, and then before the NCPs are manually tripped to limit heat input to the RCS.

Safety Significance: Failure to establish a Secondary Heat Sink through the initiation of CA flow unnecessarily challenges both the HEAT SINK and the CORE COOLING Critical Safety Functions.

Additionally, the FSAR Safety Analysis results are predicated on the assumption that at least one train of safeguards actuates and delivers a minimum amount of AFW flow to the Steam Generators. Failure to perform this task, when the ability to do so exists, results in a violation of the Facility License Condition and places the plant in an unanalyzed condition.

Inadvertent Turbine TripIATWS/SG lB Safety Valve fails Open Time Pos. Expected ActionslBehavior Comments CRITICAL TASK:

FR-S.l C Manually drive rods inward before completing the immediate actions of FR-S.l (Step 2).

Safety Significance: failure to insert negative reactivity, under the postulated plant conditions, results in an unnecessary situation in which the reactor power remains higher than it otherwise would if the action is not taken. Performance of the critical task would move the reactor power lower to prevent a subsequent an unnecessary challenge to reactor core operational limits. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

Description:

Inadvertent Turbine TrIpIATWS/SG lB Safety Valve fails Open Time Pos. Expected ActionslBehavior Comments CRITICAL TASK:

(E-0 F) Establish 450 gpm of CA Flow to the Steam Generators before transition out of FR-S.1, unless the transition is made to EPIIIAI5000IFR-H.1, and then before the NCPs are manually tripped to limit heat input to the RCS.

Safety Significance: Failure to establish a Secondary Heat Sink through the initiation of CA flow unnecessarily challenges both the HEAT SINK and the CORE COOLING Critical Safety Functions. Additionally, the FSAR Safety Analysis results are predicated on the assumption that at least one train of safeguards actuates and delivers a minimum amount of AFW flow to the Steam Generators. Failure to perform this task, when the ability to do so exists, results in a violation of the Facility License Condition and places the plant in an unanalyzed condition.

It is intended to raise power on this shift. The CF&E Sump level is high, and the crew will need to pump the contents of the sump to the Floor Drains Tank.

The following equipment is Out-Of-Service: 1A KR Pump is OOS for motor replacement.

1CAP-5610, CAST LEVEL CH 1, failed last shift (IAE is invesligating). MCB Annunciator lAD-4, A-5, BB BLOWOFF TANK LO LEVEL, has been in constant alarm over the last hour (IAE is investigating).

Upon shift turnover, before the operator initiates the power increase, the operator will pump the Containment Floor and Equipment (CF&E) Sump in accordance with Section 3.3 of Enclosure 4.2, Containment Floor and Equipment Sump and Incore Instrument Room Sump Operation, of OP/1/A/6500/001, Liquid Waste System.

Following this, the operator will raise power in accordance with Step 3.15 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation.

After this, the Compensating Voltage for Intermediate Range Channel N35 will fail. The operator will enter AP111A15500116, Malfunction of Nuclear Instrumentation, and perform Case II, Intermediate Range Malfunction The operator will address Technical Specification 3.3.1, Reactor Trip Instrumentation.

Subsequently, a leak will develop in the KC System. The operator will enter AP/1/A/5500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification 3.7.6, Component Cooling Water System.

Next, one Control Bank D Control Rod will drop into the core. The operator will respond in accordance with ARP1AD-2/D-9, RPI at Bottom Rod Drop and will implement AP/1/A15500/14, Rod Control Malfunction. 30 seconds later a second Control Rod will drop requiring that the operator manually trip the reactor. The crew will enter EPI1IAI5000IE-0, Reactor Trip or Safety Injection. The operator will transition to EP/1/A/5000/ES-0.1, Reactor Trip Response.

Shortly after entry into EP/1/A/5000/ES-0.1, the O.B.E. Exceeded annunciator will alarm, indicating that an earthquake has occurred. Within seconds a large Steam Rupture will occur outside Containment on the A Steam Generator. The operator will actuate Safety Injection, and return to EP/1/A15000/E-0, Reactor Trip or Safety Injection. Simultaneously, a Loss of Offsite Power will occur. Both Emergency Diesel Generators will start and load onto the Emergency Busses, and all SI loads will sequence on as designed.

Upon completion of E-0, the operator will transition to EP/1/A15000/E-2, Faulted Steam Generator Isolation. Upon completion of E-2, the operator will transition to either EP/1/A15000/E-1, Response to Loss of Primary or Secondary Coolant, or EP/1/A15000/ES-1.1, SI Termination.

The scenario will terminate this transition is made.

Scenario Event Description NRC Scenario 3 Critical Tasks:

ss Trip the reactor within 30 seconds of the second dropped rod (4600111 3IE1 3.19)

Safety Significance: Multiple dropped control rods are a significant reactivity transient that can have a serious effect on plant parameters under certain operating conditions, and may result in power distribution limits being exceeded. The guidance to trip the reactor is a conservative action to prevent the plant from challenging the Pzr low pressure trip setpoint, etc.; and is consistent with the conservative nature of the industry. PTIO/A/4600/l 13, Enclosure 13.19 states that it is a management expectation that the operator trip the reactor within 30 seconds of a second dropped rod.

E-2A Isolate the Faulted Steam Generator before transitioning out of E-2.

Safety Significance: Failure to isolate a Faulted SG that can be isolated causes challenges to the Critical Safety Functions that would not otherwise occur. Failure to isolate flow could result in an unwarranted Orange or Red Path condition on NC Integrity and/or Subcriticality (if cooldown is allowed to continue uncontrollably).

NOTE: This scenario will require the assignment of a Surrogate Licensed Operator to monitorlcontrol Steam Generator level, Steam Dumps, Tavg, Tcold and the operating CF Pump during this scenario. This is based on Step 3.1.2 of Enclosure 4.8 of OPIIIAI6IOO!003 which requires the assignment of this operator during reactor startup.

Safety Significance: Multiple dropped control rods are a significant reactivity transient that can have a serious effect on plant parameters under certain operating conditions, and may result in power distribution limits being exceeded. The guidance to trip the reactor is a conservative action to prevent the plant from challenging the Pzr low pressure trip setpoint, etc.; and is consistent with the conservative nature of the industry. PT/0/A/4600/113, Enclosure 13.19 states that it is a management expectation that the operator trip the reactor within 30 seconds of a second dropped rod.
