McGuire 2015 NRC Scenario #1 The plant is at 100% power (MOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The TD CA Pump is OOS for bearing replacement.

ACTION has been taken in accordance with Technical Specification LCO 3.7.5 ACTION B. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-9, E-2, B COLD LEG ACCUMULATOR ABNORMAL PRESSURE, has alarmed spuriously several times over the last hour, and has currently failed ON (IAE is investigating). The crew will perform PT/1/A/4600/001, RCCA Movement Test upon taking the shift.

Shortly after taking the watch, the crew will perform PT/1/A/4600/001, RCCA Movement Test.

During the course of the surveillance, the 1C3 Heater Drain Pump will trip. The operator will restore any individual rod bank to its initial position, place control rods in manual (and/or AUTO), and use the Control Room Expectation Manual, to immediately reduce Turbine load as needed to maintain Rx power less than pre-transient condition.

As a result of the plant transient, a Crud Burst will occur and 1EMF48, Reactor Coolant Water Radiation Monitor, will alarm. The operator will respond in accordance with ARP1RAD-2/C-3, 1EMF 48 Reactor Coolant Hi Rad, and implement AP/1/A/5500/18, High Activity in Reactor Coolant. The operator will raise Letdown flow at the request of Chemistry and address Technical Specification 3.4.16, RCS Specific Activity.

Next, 1NV-35, Variable Flow Letdown Orifice Isolation Valve, will fail Closed. The operator will enter AP/1/A/5500/12, Loss of Letdown, Charging or Seal Injection, and establish Excess Letdown.

Subsequently, electrical disturbances cause grid voltage to drop to 216 KV. The operator will respond in accordance with AP/1/A/5500/05, Generator Voltage and Electrical Grid Disturbances, and make adjustments of Main Generator voltage.

Shortly afterwards, TCC will call and report that Real Time Contingency Analysis indicates that 230KV Switchyard Voltage would not be adequate should Unit 1 trip. The operator will go to (RTCA Actions with Unit One On-line), and enter Technical Specification 3.0.3, Applicability. The operator will also need to evaluate Technical Specification 3.8.1, AC Sources

- Operating.

While implementing Enclosure 3, both IPB Fans will fail. The crew will respond in accordance with ARP1AD-11/J5, IPB AIR FLOW TROUBLE, and perform a rapid downpower in accordance with AP/1/A/5500/04, Rapid Downpower.

During the downpower, both CF Pumps will rollback to LOW Speed causing a low level condition in all Steam Generators. On the ensuing Rx Trip, the Main Turbine will fail to trip in both Auto and Manual, and the operator will need to manually close the Governor Valves. On the trip, the Steam Dumps will fail to actuate due to a C-9 failure and the SG PORVs will open to control steam pressure.

Since the 1A SG PORV is isolated, a 1A SG Safety Valve will open instead, and stick about 60%

open. Simultaneously, a lockout will occur on 1ETB and the 1A MDCA Pump will fail to start either automatically or manually and result in a total loss of CA flow. 30 seconds later a Major Steam Line Break will occur on the 1D Steamline in Containment.

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030215)

The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip and Safety Injection actuation; and then transition to EP/1/A/5000/FR-H.1, Response to Loss of Secondary Heat Sink, based on no CA flow. When 3 of 4 Steam Generator Wide Range levels are

< 36%), the operator will initiate NCS Feed and Bleed.

Once NCS Feed and Bleed is established, the TDCA Pump will be returned to service, and the operator will restore CA flow to the 1B and/or 1C Steam Generator per Step 7 of FR-H.1.

The scenario will terminate at Step 39 of FR-H.1, with the crew feeding at least one Steam Generator to restore Wide Range Level to > 12% (17% ACC).

Critical Tasks:

Manually trip the Main Turbine prior to completing the Immediate Actions of E-0 Safety Significance: Failure to trip the Main Turbine when required causes a challenge to the Subcriticality/Integrity Critical Safety Function that otherwise would not or may 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.

Establish RCS Bleed and Feed before all four Steam Generator Wide Range Levels reach 0%, and the NCS temperature and/or pressure increases.

Safety Significance: Failure to establish RCS Bleed and Feed before automatic opening of the PORVs (due to plant heatup) reduces the probability of success to establish a heat sink for the core.

This constitutes a Significant reduction of safety margin beyond that irreparably introduced by the scenario. Establishing feedwater flow into the Steam Generators offers the most effective recovery action to restore the heat sink. If all attempts to initiate feedwater flow fail, the crew must establish bleed and feed to cool the core. This is accomplished by manually initiating SI, and then manually opening the PORVs. The lower NCS pressure allows a greater ECCS flow to recover NCS inventory and force flow through the core. If this action is to be successful, it must be started before SG dryout.

SG dryout would cause NC temperature to increase, increasing NC Pressure and forcing open the PORVs automatically. If NCS pressure is at the PORV setpoint due to NCS heatup, the operator action of opening the PORVs manually may not be successful in lowering NCS pressure and increasing ECCS flow. Ultimately, the core could uncover.

Establish feedwater flow into at least one Steam Generator before transition out of FR-H.1.

Safety Significance: Failure to establish feedwater flow into at least one Steam Generator results in the crew having to rely upon the lower-priority action of having to remain in RCS Bleed and Feed to minimize the possibility of core uncovery. Failure to perform this task, when able to do so, constitutes incorrect performance that leads to degradation of the RCS and/or fuel cladding fission product barriers.

Initial Conditions: The plant is at 75% power (MOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Turnover: The following equipment is Out-Of-Service: The 1B MDCA Pump is OOS for bearing replacement. ACTION has been taken in accordance with Technical Specification LCO 3.7.5 ACTION B. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-3, F-5, BB DEMIN PNL TRBL, has alarmed spuriously several times over the last hour, and has currently failed OFF (IAE is investigating). The crew will raise power to 100% after taking the shift.

McGuire 2015 NRC Scenario #2 The plant is at 75% power (MOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The 1B MDCA Pump is OOS for bearing replacement.

ACTION has been taken in accordance with Technical Specification LCO 3.7.5 ACTION B. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-3, F-5, BB DEMIN PNL TRBL, has alarmed spuriously several times over the last hour, and has currently failed OFF (IAE is investigating). The crew will raise power to 100% after taking the shift.

Shortly after taking the watch, the operator will commence a load increase to 100% starting with Step 3.37.10 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with .19, Simple Dilution, of OP/1/A/6150/009, Boron Concentration Control, and raise Turbine load in accordance with OP/1/A/6300/001 A, Turbine-Generator Load Change.

After the load increase is started, the Control Rods will fail such that rods are moving outward in AUTO. The operator will enter AP/1/A/5500/14, Rod Control Malfunction. The control rods will subsequently remain in MANUAL.

After this, the 1B RN Pump Suction Isolation valve will inadvertently CLOSE. The operator will respond using one or more Annunciator Response Procedures and ultimately enter AP/1/A/5500/20, Loss of RN, to place the standby train in service. The operator will address Technical Specification LCO 3.7.7, Nuclear Service Water System (NSWS), and LCO 3.8.1, AC Sources - Operating.

Next, the Pzr Spray Valve Controller, 1NC-27C A Spray, demand will fail to full output. The operator will enter AP/1/A/5500/11, Pressurizer Pressure Anomalies. The operator will address Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits.

Subsequently, the 1B CF Pump will trip causing the turbine to automatically runback to 55%.

Simultaneously, a 1 gpm Steam Generator Tube Leak will occur in the 1A Steam Generator. The operator will implement AP/1/A/5500/03, Load Rejection. During the runback the operator will need to drive rods in manually.

After this, the 1A MSIV will inadvertently CLOSE, and the Reactor will fail to trip automatically and manually. Additionally, the low set Safety Valve on the 1A Steam Generator will lift and stick fully OPEN. Additionally, the TD CA Pump will trip on overspeed on auto start, and the 1A MDCA Pump will fail to start automatically. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and then transition to EP/1/A/5000/FR-S.1, Response to Nuclear Power Generation/ATWS. During the performance of FR-S.1, the operator will continuously drive rods in manually, successfully trip the Reactor locally, and manually start the 1A MDCA Pump and establish 450 gpm of flow the Steam Generators.

The Steam Generator Tube Leak will degrade to a tube rupture in the 1A Steam Generator when the reactor is locally tripped.

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030215)

After completion of FR-S.1, the operator will transition back to E-0, and then to EP/1/A/5000/E-2, Faulted Steam Generator Isolation. After the 1A Steam Generator is isolated, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant, and then, upon diagnosing the tube rupture, to EP/1/A/5000/E-3, Steam Generator Tube Rupture.

The scenario will terminate at Step 6 of E-3 after the operator has transitioned to EP/1/A/5000/ECA-3.1, SGTR with Subcooled Recovery Desired, or at Step 9 of E-3 upon initiating an NCS cooldown.

Critical Tasks:

Manually close the Failed OPEN Pzr Spray Valve before the Pressurizer pressure drops to 1945 psig.

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 NCS pressure control.

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 remains critical or returns to a critical condition.

Performance of the critical task would move the reactor towards a subcritical condition to prevent a subsequent return to criticality. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

Start the 1A MD CA Pump before transition out of FRS-.1, unless the transition is made to EP/1/A/5000/FR-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.

Isolate CA flow to the Faulted Steam Generator before an unwarranted Red Path occurs on Subcriticality or NCS Integrity.

Safety Significance: Failure to isolate a Faulted SG that can be isolated causes challenges to the Critical Safety Functions that may 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).

McGuire 2015 NRC Scenario #3 The plant is at 40% power (MOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The 1A EDG is OOS for bearing replacement. ACTION has been taken in accordance with Technical Specification LCO 3.8.1 ACTION B. The 1A SG PORV is leaking and isolated. The PORV has been declared inoperable and maintenance is being planned. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-12, E-2, A RN PUMP ABNORMAL FLOW, has alarmed spuriously several times over the last hour (IAE is investigating). The crew will raise power to 100% after taking the shift.

Shortly after taking the watch, the operator will commence a load increase to 100% starting with Step 3.35.19 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with .4, Alternate Dilute, of OP/1/A/6150/009, Boron Concentration Control, and raise Turbine load in accordance with OP/1/A/6300/001 A, Turbine-Generator Load Change.

During the power increase, the operator will discover that the Control Rods will not respond in AUTO.

The crew will enter AP/1/A/5500/14, Rod Control Malfunction, and control rods in MANUAL.

Because the crew may control the power increase such that an auto rod demand does not occur, this event may not be diagnosed until later.

Shortly after starting the power increase, AD-7/B-2, NC Pump B No. 2 Seal S-Pipe Lo Level, will alarm. The operator will address the Annunciator Response Procedure, and then use Enclosure 4.3, Filling and Draining NC Pump Standpipe, of OP/1/A/6150/002A, Reactor Coolant Pump Operation, to refill the standpipe.

After this, the 1D Steam Generator PORV will fail OPEN. The operator will respond in accordance with AP/1/A/5500/01, Steam Leak, and isolate the PORV. The operator will address Technical Specification LCO 3.7.4, Steam Generator Power Operated Relief Valves (SG PORVs), and may enter LCO 3.4.1, RCS Pressure, Temperature and Flow Departure from Nucleate Boiling (DNB)

Limits.

Subsequently, a #1 seal leak will develop on the 1A NCP such that #1 Seal leakoff flow is 5.0-5.5 gpm. The operator will respond in accordance with AP/1/A/5500/08, Malfunction of NC Pump, and address Selected Licensee Commitment 16.9.7, Standby Shutdown System. The control operators will be directed on the action to take should the #1 Seal Leakoff flow degrade to > 6 gpm (which will occur subsequently).

Shortly afterwards, a low lube oil pressure condition will develop on the Main Turbine eventually causing the Main Turbine to trip. The operator will respond in accordance with AP/1/A/5500/02, Turbine Generator Trip. The RO will need to operate the control rods manually.

While the crew is in AP-2, the 1B Hi Vibration alarm will occur and the #1 seal leak flow on the 1B NCP will rise to 6 gpm. The operator go back to Step 8 of AP-8 (Continuous Action Step), and close the 1B NCP Pzr Spray Valve, manually trip the reactor and stop the 1B NCP when reactor power is

< 5%. The crew will perform Enclosure 2, NC Pump Post Trip Actions For #1 Seal Failure, of AP8, while subsequently performing E-0.

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030215)

The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip.

On the reactor trip four control rods will fail to fully insert. The operator will transition to EP/1/A/5000/ES-0.1, Reactor Trip Response, and emergency borate per AP/1/A/5500/38, Emergency Boration And Response To Inadvertent Dilution.

Immediately following the initiation of Emergency Boration, a loss of the Unit 1 Switchyard will occur, and the 1B Emergency Diesel Generator will fail to start. The operator will immediately transition to EP/1/A/5000/ECA-0.0, Loss of All AC Power. The operator will restore power to 1ETA per Unit 2 6900V busses through SATA or SATB per Enclosure 9 Energizing Unit 1 4160V Bus From Unit 2 -

SATA or SATB.

The scenario will terminate at Step 40 of ECA-0.0, with the crew preparing to re-load the energized ESF Bus.

Critical Tasks:

Trip the Reactor prior to stopping the NCP during a high vibration condition, and trip the NCP only after Reactor power level has dropped to less than 5%.

Safety Significance: The P-8 interlock allows one NCP to be stopped less than 48% power. If a NCP is stopped in Mode 1 or 2, Tech Spec 3.4.4 requires the unit to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

In addition, T-ave for the idle loop may violate Tech Spec 3.4.2, minimum temperature for criticality.

In this case, the unit must be sub-critical within 30 minutes. The transient placed on the unit when a NCP is secured at power can challenge both reactor protection and control systems. Furthermore, an added burden is placed on the operator to stabilize the unit and shut down within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (possibly 30 minutes) to comply with Tech Specs. Even though the plant is designed and analyzed to operate in this configuration for a short time, station management has decided that the conservative approach to dealing with this transient is to trip the reactor anytime a NCP malfunction warrants stopping a pump in Mode 1 or 2. Guidance is given to wait until reactor power is less than 5% before stopping the NC pump. This will ensure the NC pump will provide adequate flow/core cooling until reactor power is sufficiently low enough to preclude a challenge to fuel integrity. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

Close the #1 Seal Return Valve for the 1B NCP prior to failure of the #2 Seal as indicated by a rise and subsequent substantial lowering of #1 Seal Leakoff Flow.

Safety Significance: According to Enclosure 2 of AP-8, the Seal Water Return Valve must be closed within 3-5 minutes after stopping the NCP. If the valve is NOT closed, the NCS leak will continue until isolated, and could degrade the #2 and 3 Seals. According to the AP8 Background Document, closing the seal return valve within 3 to 5 minutes during a #1 seal failure event does not meet the criteria of "high PRA values" as determined by the Severe Accident Analysis Group. For McGuire, this corresponds to a Risk Achievement Worth (RAW) greater than or equal to 1.04. PIP M-03-1992 documents the events that meet these criteria. As such this action is not a McGuire 'time critical action', but is a management expectation and prudent action to prevent damage to the #2 and #3 seals. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030215)

Energize at least one AC Emergency Bus From Unit 2.

Safety Significance: Failure to energize an AC Emergency Bus when able to do so constitutes mis-operation or incorrect performance which leads to degraded emergency power capacity. Failure to perform the Critical Task may result in a needless challenge and/or degradation of a fission product barrier at the point of the remaining intact RCP Seals, and will result in the inability to add inventory through the ECCS during the existing and potentially subsequent small break LOCA(s). Since the conditions existed to re-energize an ESF Bus from Unit 2 via the SATA or SATB, not taking this action constitutes incorrect performance that leads to degradation of the RCS and/or fuel cladding fission product barriers.

McGuire 2015 NRC Scenario #4 The plant is at 4% power (BOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The 1A CM Pump is OOS for bearing replacement. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-1, F-9, DEH/MSR SYSTEM MALFUNCTION, has alarmed spuriously several times over the last hour, and has currently failed ON (IAE is investigating). The crew will raise power to 12-18% and stabilize reactor power, and making preparations to synch the Turbine to the Grid while maintenance is completed.

Shortly after taking the watch, the operator will raise power to 12-18% starting with Step 3.25 of .1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation.

Next, the 1A2 KC Pump will trip. The operator will enter AP/1/A/5500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System.

Just after this, the DRPI for Control Rod M-12 will fail and indicate the rod on the bottom. The operator will respond in accordance with 1AD-2/D-10, RPI Urgent Failure, and address Technical Specification LCO 3.1.7, Rod Position Indication.

Subsequently, 1EMF-34, S/G Sample Radiation Monitor, will fail HIGH, however, one of the SG Blowdown Control Valves will NOT automatically close. The operator will respond in accordance with OP/1/A/6100/010 Q, Annunciator Response for 1RAD-1, C3, 1EMF 34 S/G SAMPLE HI RAD, and manually close the valve. The operator may enter Case I of AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The crew will determine that the alarm is due to a failure, and NOT an actual high radioactivity condition.

Shortly afterwards, a 50-75 gpm leak will occur on the Letdown Line, in the Aux Building, upstream of the Letdown Heat Exchanger. The operator will enter Case II of AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The operator will place the Outside Air Pressure Filter Train in service per Enclosure 4.4 of OP/0/A/6450/011, Control Area Ventilation/Chilled Water System. The operator will address Technical Specification LCO 3.4.13, RCS Operational Leakage, and Selected Licensee Commitment 16.9.7, Standby Shutdown System.

Just after the leak isolation, 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/A/5500/14, Rod Control Malfunction. Shortly after this, a second Control Rod will drop requiring that the operator manually trip the reactor.

Upon the reactor trip, the B Train of Safety Injection will inadvertently actuate. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip and Safety Injection actuation, actuating the A Train of SI in the process. The crew will reset SI and stop all ECCS Pumps except for one NV Pump within 15 minutes.

When the crew attempts to close 1NI-10B, Unit 1 NV Pumps To NC Cold Legs Cont Outside Isol, it will be discovered that the valve will not close. The operator will be required to dispatch an operator to locally close 1NI-10B.

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030515)

Ultimately, the crew will transition to step 9 of EP/1/A/5000/ES-1.1, Safety Injection Termination.

The scenario will terminate in EP/1/A/5000/ES-1.1 at Step 14.m RNO after the CRS determines to establish Excess Letdown.

Critical Tasks:

Trip the Reactor upon recognition of the second dropped rod.

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 form 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.

Terminate SI by closing 1NI-9A and dispatching an operator to locally close 1NI-10B 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/A/4600/113, 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 > 500oF. If this action is not taken, the conclusions of the Safety Analysis are invalid, and violates a License Condition.

McGuire 2015 NRC Scenario #5 The plant is at 100% power (MOL). The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

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

The 1A S/G PORV is isolated and its actuator is currently removed for maintenance.

1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-1, F-9, DEH/MSR SYSTEM MALFUNCT, has failed to OFF (IAE is investigating).

Shortly after taking the watch, the Turbine Driven CA Pump will inadvertently start causing the plant to cooldown and reactor power to rise. The crew will recognize that the pump should not be running and stop the pump using OP/1/A/6250/002, Auxiliary Feedwater System. The operator may use AP/1/A/5500/1, Steam Leak, to diagnose the failure.

The operator will address Technical Specification 3.7.5, Auxiliary Feedwater (AFW)

System, and SLC 16.9.7, Standby Shutdown System.

Next, the 1B SG FRV Controller will fail to MANUAL and the FRV Bypass valve will fail fully open resulting in the Feedwater Control Valve for the 1B SG closing and causing SG Level to lower. The operator will respond in accordance with AP/1/A/5500/06, S/G Feedwater Malfunction, and control the 1B SG Level manually.

Following this, a 70-90 gpm leak will develop on the reactor head from a Control Rod Guide Tube. The crew will implement AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The operator will address Technical Specification 3.4.13, RCS Operational Leakage. Ultimately, the crew will enter AP/1/A/5500/4, Rapid Downpower.

During the downpower, a failure will occur in the Turbine Control Unit causing the unit to shift from Operator Auto to Manual control. The operator will address 1AD-1/F-4, TURBINE IN MANUAL, and control the Turbine manually during the downpower in accordance with OP/1/A/6300/001A, Enclosure 4.1, Turbine Generator Load Change.

After this, Control Rod D-4 will be ejected from the core causing a 1000 gpm Small Break LOCA. The operator will trip the Reactor and actuate Safety Injection, and then enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection. On the Safety Injection actuation the EDG A Sequencer will fail to automatically sequence, and the operator will need to manually start ECCS loads. Additionally, the 1B NV Pump will trip, and the 1B NI Pump will fail to start automatically. The operator will be required to start the 1B NI Pump manually.

Upon completion of E-0, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant. At that time a second Control Rod (F-14) will be ejected from the core causing the Small Break LOCA to degrade to the point at which the NC Pumps will need to be tripped. The scenario will terminate at Step 9 of E-1, after the crew has been directed to return back to the beginning of E-1.

Appendix D Scenario Outline Form ES-D-1 Final (Rev_030515)

Critical Tasks:

Establish flow from at least one high-head ECCS Pump before transition out of E-0.

Safety Significance: Failure to establish flow from the NV System after failure of the automatic actuation constitutes a demonstrated inability by the operator to recognize a failure and/or correct a failure of an ESF System or component. The FSAR analyses of response to high energy line breaks assume that at least one train of safeguards actuates. If the minimum assumed ESF components are NOT actuated the Safety Analyses results are invalid. Because compliance with the assumptions in the FSAR is part of the facility license, failure to comply constitutes a violation of the license condition.

Trip NC Pumps within 5 minutes of loss of SCM (4600/113/E13.1)

Safety Significance: Failure to trip all NCPs on a loss of subcooled margin can lead to core uncovery and to fuel temperatures in excess of 2200oF. PT/0/A/4600/113, Enclosure 13.1 states that McGuire is committed to having NC Pumps tripped within 5 minutes of a loss of subcooling. The Safety Analysis recommends that the NC Pumps be tripped within 2 minutes to limit the depth and duration of core uncovery. It is a management expectation that the NC Pumps be tripped as quickly as possible, but within 5 minutes of a loss of subcooling. Failure to take this action represents mis-operation by the operator which leads to degradation of the fuel cladding fission produce barrier, and a violation of a license condition.

The following equipment is Out-Of-Service: The TD CA Pump is OOS for bearing replacement.

ACTION has been taken in accordance with Technical Specification LCO 3.7.5 ACTION B. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-9, E-2, B COLD LEG ACCUMULATOR ABNORMAL PRESSURE, has alarmed spuriously several times over the last hour, and has currently failed ON (IAE is investigating). The crew will perform PT/1/A/4600/001, RCCA Movement Test upon taking the shift.

Shortly after taking the watch, the crew will perform PT/1/A/4600/001, RCCA Movement Test.

During the course of the surveillance, the 1C3 Heater Drain Pump will trip. The operator will restore any individual rod bank to its initial position, place control rods in manual (and/or AUTO),

and use the Control Room Expectation Manual, to immediately reduce Turbine load as needed to maintain Rx power less than pre-transient condition.

As a result of the plant transient, a Crud Burst will occur and 1EMF48, Reactor Coolant Water Radiation Monitor, will alarm. The operator will respond in accordance with ARP1RAD-2/C-3, 1EMF 48 Reactor Coolant Hi Rad, and implement AP/1/A/5500/18, High Activity in Reactor Coolant. The operator will raise Letdown flow at the request of Chemistry and address Technical Specification 3.4.16, RCS Specific Activity.

Next, 1NV-35, Variable Flow Letdown Orifice Isolation Valve, will fail Closed. The operator will enter AP/1/A/5500/12, Loss of Letdown, Charging or Seal Injection, and establish Excess Letdown.

Subsequently, electrical disturbances cause grid voltage to drop to 216 KV. The operator will respond in accordance with AP/1/A/5500/05, Generator Voltage and Electrical Grid Disturbances, and make adjustments of Main Generator voltage.

Shortly afterwards, TCC will call and report that Real Time Contingency Analysis indicates that 230KV Switchyard Voltage would not be adequate should Unit 1 trip. The operator will go to (RTCA Actions with Unit One On-line), and enter Technical Specification 3.0.3, Applicability. The operator will also need to evaluate Technical Specification 3.8.1, AC Sources

- Operating.

While implementing Enclosure 3, both IPB Fans will fail. The crew will respond in accordance with ARP1AD-11/J5, IPB AIR FLOW TROUBLE, and perform a rapid downpower in accordance with AP/1/A/5500/04, Rapid Downpower.

During the downpower, both CF Pumps will rollback to LOW Speed causing a low level condition in all Steam Generators. On the ensuing Rx Trip, the Main Turbine will fail to trip in both Auto and Manual, and the operator will need to manually close the Governor Valves. On the trip, the Steam Dumps will fail to actuate due to a C-9 failure and the SG PORVs will open to control steam pressure. Since the 1A SG PORV is isolated, a 1A SG Safety Valve will open instead, and stick about 60% open. Simultaneously, a lockout will occur on 1ETB and the 1A MDCA Pump will fail to start either automatically or manually and result in a total loss of CA flow. 30 seconds later a Major Steam Line Break will occur on the 1D Steamline in Containment.

Scenario Event Description NRC Scenario 1 The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip and Safety Injection actuation; and then transition to EP/1/A/5000/FR-H.1, Response to Loss of Secondary Heat Sink, based on no CA flow. When 3 of 4 Steam Generator Wide Range levels are < 36%), the operator will initiate NCS Feed and Bleed.

Once NCS Feed and Bleed is established, the TDCA Pump will be returned to service, and the operator will restore CA flow to the 1B and/or 1C Steam Generator per Step 7 of FR-H.1.

The scenario will terminate at Step 39 of FR-H.1, with the crew feeding at least one Steam Generator to restore Wide Range Level to > 12% (17% ACC).

Critical Tasks:

Manually trip the Main Turbine prior to completing the Immediate Actions of E-0 Safety Significance: Failure to trip the Main Turbine when required causes a challenge to the Subcriticality/Integrity Critical Safety Function that otherwise would not or may 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.

Establish RCS Bleed and Feed before all four Steam Generator Wide Range Levels reach 0%, and the NCS temperature and/or pressure increases.

Safety Significance: Failure to establish RCS Bleed and Feed before automatic opening of the PORVs (due to plant heatup) reduces the probability of success to establish a heat sink for the core. This constitutes a Significant reduction of safety margin beyond that irreparably introduced by the scenario. Establishing feedwater flow into the Steam Generators offers the most effective recovery action to restore the heat sink. If all attempts to initiate feedwater flow fail, the crew must establish bleed and feed to cool the core. This is accomplished by manually initiating SI, and then manually opening the PORVs. The lower NCS pressure allows a greater ECCS flow to recover NCS inventory and force flow through the core. If this action is to be successful, it must be started before SG dryout. SG dryout would cause NC temperature to increase, increasing NC Pressure and forcing open the PORVs automatically. If NCS pressure is at the PORV setpoint due to NCS heatup, the operator action of opening the PORVs manually may not be successful in lowering NCS pressure and increasing ECCS flow. Ultimately, the core could uncover.

Establish feedwater flow into at least one Steam Generator before transition out of FR-H.1.

Safety Significance: Failure to establish feedwater flow into at least one Steam Generator results in the crew having to rely upon the lower-priority action of having to remain in RCS Bleed and Feed to minimize the possibility of core uncovery. Failure to perform this task, when able to do so, constitutes incorrect performance that leads to degradation of the RCS and/or fuel cladding fission product barriers.

On the ensuing Rx Trip, the Main Turbine will fail to trip in both Auto and Manual, and the operator will need to manually close the Governor Valves. On the trip, the Steam Dumps will fail to actuate due to a C-9 failure and the SG PORVs will open to control steam pressure. Since the 1A SG PORV is isolated, a 1A SG Safety Valve will open instead, and stick about 60% open. Simultaneously, a lockout will occur on 1ETB and the 1A MDCA Pump will fail to start either automatically or manually and result in a total loss of CA flow. 30 seconds later a Major Steam Line Break will occur on the 1D Steamline in Containment. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip and Safety Injection actuation; and then transition to EP/1/A/5000/FR-H.1, Response to Loss of Secondary Heat Sink, based on no CA flow. When 3 of 4 Steam Generator Wide Range levels are < 36%), the operator will initiate NCS Feed and Bleed. Once NCS Feed and Bleed is established, the TDCA Pump will be returned to service, and the operator will restore CA flow to the 1B and/or 1C Steam Generator per Step 7 of FR-H.1. The scenario will terminate at Step 39 of FR-H.1, with the crew feeding at least one Steam Generator to restore Wide Range Level to > 12% (17% ACC).

Both CF Pumps Roll Back to Low Speed/Turbine fails to Trip in AUTO and MANUAL/ C-9 fails to Actuate/1A Safety Valve Sticks OPEN/1A MD CA Pumps fails to start in AUTO/Man/1ETB Lockout/1D Steam Break in Containment/ TD CA Pump is Restored Time Pos. Expected Actions/Behavior Comments Critical Task:

Establish RCS Bleed and Feed before all four Steam Generator Wide Range Levels reach 0%, and the NCS temperature and/or pressure increases.

Safety Significance: Failure to establish RCS Bleed and Feed before automatic opening of the PORVs (due to plant heatup) reduces the probability of success to establish a heat sink for the core. This constitutes a Significant reduction of safety margin beyond that irreparably introduced by the scenario. Establishing feedwater flow into the Steam Generators offers the most effective recovery action to restore the heat sink. If all attempts to initiate feedwater flow fail, the crew must establish bleed and feed to cool the core. This is accomplished by manually initiating SI, and then manually opening the PORVs. The lower NCS pressure allows a greater ECCS flow to recover NCS inventory and force flow through the core. If this action is to be successful, it must be started before SG dryout. SG dryout would cause NC temperature to increase, increasing NC Pressure and forcing open the PORVs automatically. If NCS pressure is at the PORV setpoint due to NCS heatup, the operator action of opening the PORVs manually may not be successful in lowering NCS pressure and increasing ECCS flow. Ultimately, the core could uncover.

BOP (Step 28) Isolate NV Recirc flowpath as follows:

• CLOSE the following valves:

• 1NV-150B (U1 NV Pump Recirc Isol)

The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The 1B MDCA Pump is OOS for bearing replacement. ACTION has been taken in accordance with Technical Specification LCO 3.7.5 ACTION B. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance.

1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-3, F-5, BB DEMIN PNL TRBL, has alarmed spuriously several times over the last hour, and has currently failed OFF (IAE is investigating). The crew will raise power to 100%

after taking the shift.

Shortly after taking the watch, the operator will commence a load increase to 100% starting with Step 3.37.10 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with .19, Simple Dilution, of OP/1/A/6150/009, Boron Concentration Control, and raise Turbine load in accordance with OP/1/A/6300/001 A, Turbine-Generator Load Change.

After the load increase is started, the Control Rods will fail such that rods are moving outward in AUTO. The operator will enter AP/1/A/5500/14, Rod Control Malfunction. The control rods will subsequently remain in MANUAL.

After this, the 1B RN Pump Suction Isolation valve will inadvertently CLOSE. The operator will respond using one or more Annunciator Response Procedures and ultimately enter AP/1/A/5500/20, Loss of RN, to place the standby train in service. The operator will address Technical Specification LCO 3.7.7, Nuclear Service Water System (NSWS), and LCO 3.8.1, AC Sources - Operating.

Next, the Pzr Spray Valve Controller, 1NC-27C A Spray, demand will fail to full output. The operator will enter AP/1/A/5500/11, Pressurizer Pressure Anomalies. The operator will address Technical Specification LCO 3.4.1, RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits.

Subsequently, the 1B CF Pump will trip causing the turbine to automatically runback to 55%.

Simultaneously, a 1 gpm Steam Generator Tube Leak will occur in the 1A Steam Generator. The operator will implement AP/1/A/5500/03, Load Rejection. During the runback the operator will need to drive rods in manually.

After this, the 1A MSIV will inadvertently CLOSE, and the Reactor will fail to trip automatically and manually. Additionally, the low set Safety Valve on the 1A Steam Generator will lift and stick fully OPEN. Additionally, the TD CA Pump will trip on overspeed on auto start, and the 1A MDCA Pump will fail to start automatically. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and then transition to EP/1/A/5000/FR-S.1, Response to Nuclear Power Generation/ATWS. During the performance of FR-S.1, the operator will continuously drive rods in manually, successfully trip the Reactor locally, and manually start the 1A MDCA Pump and establish 450 gpm of flow the Steam Generators.

The Steam Generator Tube Leak will degrade to a tube rupture in the 1A Steam Generator when the reactor is locally tripped.

Scenario Event Description NRC Scenario 2 After completion of FR-S.1, the operator will transition back to E-0, and then to EP/1/A/5000/E-2, Faulted Steam Generator Isolation. After the 1A Steam Generator is isolated, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant, and then, upon diagnosing the tube rupture, to EP/1/A/5000/E-3, Steam Generator Tube Rupture.

The scenario will terminate at Step 6 of E-3 after the operator has transitioned to EP/1/A/5000/ECA-3.1, SGTR with Subcooled Recovery Desired, or at Step 9 of E-3 upon initiating an NCS cooldown.

Critical Tasks:

Manually close the Failed OPEN Pzr Spray Valve before the Pressurizer pressure drops to 1945 psig.

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 NCS pressure control.

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 remains critical or returns to a critical condition. Performance of the critical task would move the reactor towards a subcritical condition to prevent a subsequent return to criticality. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

Start the 1A MD CA Pump before transition out of FRS-.1, unless the transition is made to EP/1/A/5000/FR-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.

Isolate CA flow to the Faulted Steam Generator before an unwarranted Red Path occurs on Subcriticality or NCS Integrity.

Safety Significance: Failure to isolate a Faulted SG that can be isolated causes challenges to the Critical Safety Functions that may 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).

After completion of FR-S.1, the operator will transition back to E-0, and then to EP/1/A/5000/E-2, Faulted Steam Generator Isolation. After the 1A Steam Generator is isolated, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant, and then, upon diagnosing the tube rupture, to EP/1/A/5000/E-3, Steam Generator Tube Rupture. The scenario will terminate at Step 6 of E-3 after the operator has transitioned to EP/1/A/5000/ECA-3.1, SGTR with Subcooled Recovery Desired, or at Step 9 of E-3 upon initiating an NCS cooldown.

• Trip the reactor.

• IF reactor will not trip, THEN manually NOTE: The RO will insert rods. manually drive Rods inward.

Critical Task:

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 remains critical or returns to a critical condition. Performance of the critical task would move the reactor towards a subcritical condition to prevent a subsequent return to criticality. A failure to insert negative reactivity constitutes a mis-operation or incorrect crew performance which leads to incorrect reactivity control.

• Check N/R Level in at least 3 S/Gs -

GREATER THAN 17%.

Critical Task:

Start the 1A MD CA Pump before transition out of FRS-.1, unless the transition is made to EP/1/A/5000/FR-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.

BOP (Step 5) Initiate emergency boration of NC System as follows:

The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: The 1A EDG is OOS for bearing replacement.

ACTION has been taken in accordance with Technical Specification LCO 3.8.1 ACTION B. The 1A SG PORV is leaking and isolated. The PORV has been declared inoperable and maintenance is being planned. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-12, E-2, A RN PUMP ABNORMAL FLOW, has alarmed spuriously several times over the last hour (IAE is investigating). The crew will raise power to 100% after taking the shift.

Shortly after taking the watch, the operator will commence a load increase to 100% starting with Step 3.35.19 of Enclosure 4.1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation. The operator will dilute the NC System Boron concentration in accordance with .4, Alternate Dilute, of OP/1/A/6150/009, Boron Concentration Control, and raise Turbine load in accordance with OP/1/A/6300/001 A, Turbine-Generator Load Change.

During the power increase, the operator will discover that the Control Rods will not respond in AUTO. The crew will enter AP/1/A/5500/14, Rod Control Malfunction, and control rods in MANUAL. Because the crew may control the power increase such that an auto rod demand does not occur, this event may not be diagnosed until later.

Shortly after starting the power increase, AD-7/B-2, NC Pump B No. 2 Seal S-Pipe Lo Level, will alarm. The operator will address the Annunciator Response Procedure, and then use Enclosure 4.3, Filling and Draining NC Pump Standpipe, of OP/1/A/6150/002A, Reactor Coolant Pump Operation, to refill the standpipe.

After this, the 1D Steam Generator PORV will fail OPEN. The operator will respond in accordance with AP/1/A/5500/01, Steam Leak, and isolate the PORV. The operator will address Technical Specification LCO 3.7.4, Steam Generator Power Operated Relief Valves (SG PORVs), and may enter LCO 3.4.1, RCS Pressure, Temperature and Flow Departure from Nucleate Boiling (DNB) Limits.

Subsequently, a #1 seal leak will develop on the 1A NCP such that #1 Seal leakoff flow is 5.0-5.5 gpm. The operator will respond in accordance with AP/1/A/5500/08, Malfunction of NC Pump, and address Selected Licensee Commitment 16.9.7, Standby Shutdown System. The control operators will be directed on the action to take should the #1 Seal Leakoff flow degrade to > 6 gpm (which will occur subsequently).

Shortly afterwards, a low lube oil pressure condition will develop on the Main Turbine eventually causing the Main Turbine to trip. The operator will respond in accordance with AP/1/A/5500/02, Turbine Generator Trip. The RO will need to operate the control rods manually.

While the crew is in AP-2, the 1B Hi Vibration alarm will occur and the #1 seal leak flow on the 1B NCP will rise to 6 gpm. The operator go back to Step 8 of AP-8 (Continuous Action Step), and close the 1B NCP Pzr Spray Valve, manually trip the reactor and stop the 1B NCP when reactor power is < 5%. The crew will perform Enclosure 2, NC Pump Post Trip Actions For #1 Seal Failure, of AP8, while subsequently performing E-0.

Scenario Event Description NRC Scenario 3 The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip.

On the reactor trip four control rods will fail to fully insert. The operator will transition to EP/1/A/5000/ES-0.1, Reactor Trip Response, and emergency borate per AP/1/A/5500/38, Emergency Boration And Response To Inadvertent Dilution.

Immediately following the initiation of Emergency Boration, a loss of the Unit 1 Switchyard will occur, and the 1B Emergency Diesel Generator will fail to start. The operator will immediately transition to EP/1/A/5000/ECA-0.0, Loss of All AC Power. The operator will restore power to 1ETA per Unit 2 6900V busses through SATA or SATB per Enclosure 9 Energizing Unit 1 4160V Bus From Unit 2 - SATA or SATB.

The scenario will terminate at Step 40 of ECA-0.0, with the crew preparing to re-load the energized ESF Bus.

Critical Tasks:

Trip the Reactor prior to stopping the NCP during a high vibration condition, and trip the NCP only after Reactor power level has dropped to less than 5%.

Safety Significance: The P-8 interlock allows one NCP to be stopped less than 48% power. If a NCP is stopped in Mode 1 or 2, Tech Spec 3.4.4 requires the unit to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

In addition, T-ave for the idle loop may violate Tech Spec 3.4.2, minimum temperature for criticality. In this case, the unit must be sub-critical within 30 minutes. The transient placed on the unit when a NCP is secured at power can challenge both reactor protection and control systems. Furthermore, an added burden is placed on the operator to stabilize the unit and shut down within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (possibly 30 minutes) to comply with Tech Specs. Even though the plant is designed and analyzed to operate in this configuration for a short time, station management has decided that the conservative approach to dealing with this transient is to trip the reactor anytime a NCP malfunction warrants stopping a pump in Mode 1 or 2. Guidance is given to wait until reactor power is less than 5% before stopping the NC pump. This will ensure the NC pump will provide adequate flow/core cooling until reactor power is sufficiently low enough to preclude a challenge to fuel integrity. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

Close the #1 Seal Return Valve for the 1B NCP prior to failure of the #2 Seal as indicated by a rise and subsequent substantial lowering of #1 Seal Leakoff Flow.

Safety Significance: According to Enclosure 2 of AP-8, the Seal Water Return Valve must be closed within 3-5 minutes after stopping the NCP. If the valve is NOT closed, the NCS leak will continue until isolated, and could degrade the #2 and 3 Seals. According to the AP8 Background Document, closing the seal return valve within 3 to 5 minutes during a #1 seal failure event does not meet the criteria of "high PRA values" as determined by the Severe Accident Analysis Group.

For McGuire, this corresponds to a Risk Achievement Worth (RAW) greater than or equal to 1.04.

PIP M-03-1992 documents the events that meet these criteria. As such this action is not a McGuire 'time critical action', but is a management expectation and prudent action to prevent damage to the #2 and #3 seals. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

Scenario Event Description NRC Scenario 3 Energize at least one AC Emergency Bus From Unit 2.

Safety Significance: Failure to energize an AC Emergency Bus when able to do so constitutes mis-operation or incorrect performance which leads to degraded emergency power capacity.

Failure to perform the Critical Task may result in a needless challenge and/or degradation of a fission product barrier at the point of the remaining intact RCP Seals, and will result in the inability to add inventory through the ECCS during the existing and potentially subsequent small break LOCA(s). Since the conditions existed to re-energize an ESF Bus from Unit 2 via the SATA or SATB, not taking this action constitutes incorrect performance that leads to degradation of the RCS and/or fuel cladding fission product barriers.

1. 1 Seal Leak on 1B NCP Degrades/4 Control Rods fail to Fully Insert on Rx Trip/Loss of Switchyard to Unit 1/1B EDG fails to START While the crew is in AP-2, the 1B Hi Vibration alarm will occur and the #1 seal leak flow on the 1B NCP will rise to 6 gpm. The operator go back to Step 8 of AP-8 (Continuous Action Step), and close the 1B NCP Pzr Spray Valve, manually trip the reactor and stop the 1B NCP when reactor power is < 5%. The crew will perform Enclosure 2, NC Pump Post Trip Actions For #1 Seal Failure, of AP8, while subsequently performing E-0. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip. On the reactor trip four control rods will fail to fully insert. The operator will transition to EP/1/A/5000/ES-0.1, Reactor Trip Response, and emergency borate per AP/1/A/5500/38, Emergency Boration And Response To Inadvertent Dilution.

Immediately following the initiation of Emergency Boration, a loss of the Unit 1 Switchyard will occur, and the 1B Emergency Diesel Generator will fail to start. The operator will immediately transition to EP/1/A/5000/ECA-0.0, Loss of All AC Power.

• Trip reactor BOP

• WHEN reactor power less than 5%,

THEN stop affected NC pump.

Critical Task:

Trip the Reactor prior to stopping the NCP during a high vibration condition, and trip the NCP only after Reactor power level has dropped to less than 5%.

Safety Significance: The P-8 interlock allows one NCP to be stopped less than 48%

power. If a NCP is stopped in Mode 1 or 2, Tech Spec 3.4.4 requires the unit to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. In addition, T-ave for the idle loop may violate Tech Spec 3.4.2, minimum temperature for criticality. In this case, the unit must be sub-critical within 30 minutes. The transient placed on the unit when a NCP is secured at power can challenge both reactor protection and control systems. Furthermore, an added burden is placed on the operator to stabilize the unit and shut down within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (possibly 30 minutes) to comply with Tech Specs. Even though the plant is designed and analyzed to operate in this configuration for a short time, station management has decided that the conservative approach to dealing with this transient is to trip the reactor anytime a NCP malfunction warrants stopping a pump in Mode 1 or 2. Guidance is given to wait until reactor power is less than 5% before stopping the NC pump. This will ensure the NC pump will provide adequate flow/core cooling until reactor power is sufficiently low enough to preclude a challenge to fuel integrity. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

NOTE: The CRS will direct the BOP to perform Enclosure 2, and continue in AP-8 with the RO.

If so, BOP Examiner follow actions of Enclosure 2.

Other Examiners follow AP-8 Actions on Page 41.

Expected Actions/Behavior Comments AP/1/A/5500/08, MALFUNCTION OF NC PUMP ENCLOSURE 2, NC PUMP POST TRIP ACTIONS FOR #1 SEAL FAILURE Examiner NOTE: Follow the actions associated with Enclosure 2 if BOP is assigned by CRS to perform.

BOP (Step 1) Record time of NC pump shutdown.

BOP (Step 2) Check if seal cooling available to affected pump:

• Seal injection established (Normal or SSF Supply)

• KC to Thermal Barrier established.

BOP (Step 3) Check if any NC Pump number 1 seal leakoff flow - GREATER THAN OR EQUAL TO 6 GPM.

BOP (Step 4) Maintain seal injection flow greater than 9 GPM to affected pump(s).

BOP (Step 5) WHEN affected NC pump has been off 3 minutes, THEN immediately perform the following:

• CLOSE affected NC pump seal return valve:

• 1NV-50B (B NC Pump Seal Return NOTE: The BOP will close Isol) this valve approximately three minutes after stopping the 1B NC Pump.

• OPEN all of the following valves:

• OPEN 1KC-394A (A NC Pump Therm Bar Otlt)

• OPEN 1KC-345A (C NC Pump Therm Bar Otlt)

• OPEN 1KC-364B (B NC Pump Therm Bar Otlt)

• OPEN 1KC-413B (D NC Pump Therm Bar Otlt)

Critical Task:

Close the #1 Seal Return Valve for the 1B NCP prior to failure of the #2 Seal as indicated by a rise and subsequent substantial lowering of #1 Seal Leakoff Flow.

Safety Significance: According to Enclosure 2 of AP-8, the Seal Water Return Valve must be closed within 3-5 minutes after stopping the NCP. If the valve is NOT closed, the NCS leak will continue until isolated, and could degrade the #2 and 3 Seals.

According to the AP8 Background Document, closing the seal return valve within 3 to 5 minutes during a #1 seal failure event does not meet the criteria of "high PRA values" as determined by the Severe Accident Analysis Group. For McGuire, this corresponds to a Risk Achievement Worth (RAW) greater than or equal to 1.04. PIP M-03-1992 documents the events that meet these criteria. As such this action is not a McGuire

'time critical action', but is a management expectation and prudent action to prevent damage to the #2 and #3 seals. If the action can be taken, and is not taken, this demonstrates mis-operation or incorrect operation that could unnecessarily challenge a fission product barrier (NCS).

Description:

1. 1 Seal Leak on 1B NCP Degrades/4 Control Rods fail to Fully Insert on Rx Trip/Loss of Switchyard to Unit 1/1B EDG fails to START Time Pos. Expected Actions/Behavior Comments Critical Task:

Energize at least one AC Emergency Bus From Unit 2.

Safety Significance: Failure to energize an AC Emergency Bus when able to do so constitutes mis-operation or incorrect performance which leads to degraded emergency power capacity. Failure to perform the Critical Task may result in a needless challenge and/or degradation of a fission product barrier at the point of the remaining intact RCP Seals, and will result in the inability to add inventory through the ECCS during the existing and potentially subsequent small break LOCA(s). Since the conditions existed to re-energize an ESF Bus from Unit 2 via the SATA or SATB, not taking this action constitutes incorrect performance that leads to degradation of the RCS and/or fuel cladding fission product barriers.

At the discretion of the Lead Examiner terminate the exam.

The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

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

The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-1, F-9, DEH/MSR SYSTEM MALFUNCTION, has alarmed spuriously several times over the last hour, and has currently failed ON (IAE is investigating). The crew will raise power to 12-18% and stabilize reactor power, and making preparations to synch the Turbine to the Grid while maintenance is completed.

Shortly after taking the watch, the operator will raise power to 12-18% starting with Step 3.25 of .1, Power Increase, of OP/1/A/6100/003, Controlling Procedure for Unit Operation.

Next, the 1A2 KC Pump will trip. The operator will enter AP/1/A/5500/21, Loss of KC or KC System Leakage. The operator will address Technical Specification LCO 3.7.6, Component Cooling Water (CCW) System.

Just after this, the DRPI for Control Rod M-12 will fail and indicate the rod on the bottom. The operator will respond in accordance with 1AD-2/D-10, RPI Urgent Failure, and address Technical Specification LCO 3.1.7, Rod Position Indication.

Subsequently, 1EMF-34, S/G Sample Radiation Monitor, will fail HIGH, however, one of the SG Blowdown Control Valves will NOT automatically close. The operator will respond in accordance with OP/1/A/6100/010 Q, Annunciator Response for 1RAD-1, C3, 1EMF 34 S/G SAMPLE HI RAD, and manually close the valve. The operator may enter Case I of AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The crew will determine that the alarm is due to a failure, and NOT an actual high radioactivity condition.

Shortly afterwards, a 50-75 gpm leak will occur on the Letdown Line, in the Aux Building, upstream of the Letdown Heat Exchanger. The operator will enter Case II of AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The operator will place the Outside Air Pressure Filter Train in service per Enclosure 4.4 of OP/0/A/6450/011, Control Area Ventilation/Chilled Water System. The operator will address Technical Specification LCO 3.4.13, RCS Operational Leakage, and Selected Licensee Commitment 16.9.7, Standby Shutdown System.

Just after the leak isolation, 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/A/5500/14, Rod Control Malfunction. Shortly after this, a second Control Rod will drop requiring that the operator manually trip the reactor.

Upon the reactor trip, the B Train of Safety Injection will inadvertently actuate. The operator will enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection, and verify reactor trip and Safety Injection actuation, actuating the A Train of SI in the process. The crew will reset SI and stop all ECCS Pumps except for one NV Pump within 15 minutes.

When the crew attempts to close 1NI-10B, Unit 1 NV Pumps To NC Cold Legs Cont Outside Isol, it will be discovered that the valve will not close. The operator will be required to dispatch an operator to locally close 1NI-10B.

Scenario Event Description NRC Scenario 4 Ultimately, the crew will transition to step 9 of EP/1/A/5000/ES-1.1, Safety Injection Termination.

The scenario will terminate in EP/1/A/5000/ES-1.1 at Step 14.m RNO after the CRS determines to establish Excess Letdown.

Critical Tasks:

Trip the Reactor upon recognition of the second dropped rod.

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 form 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.

Terminate SI by closing 1NI-9A and dispatching an operator to locally close 1NI-10B 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/A/4600/113, 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 > 500oF. If this action is not taken, the conclusions of the Safety Analysis are invalid, and violates a License Condition.

Trip the Reactor upon recognition of the second dropped rod 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 form challenging the Pzr low pressure trip setpoint, etc.; and is consistent with the conservative nature of the industry.

• Do not continue until both 1NI9A and 1NI10B are closed.

Examiner NOTE:

Mark Time of 1NI-9A Closure and the dispatch of the AO to close 1NI-10B (To the Minute):

Critical Task:

Terminate SI by closing 1NI-9A and dispatching an operator to locally close 1NI-10B 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/A/4600/113, 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 > 500oF. If this action is not taken, the conclusions of the Safety Analysis are invalid, and violates a License Condition.

The area has experienced severe weather over the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and this is expected to continue for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The following equipment is Out-Of-Service: 1A RV Pump is OOS for motor replacement. The 1A S/G PORV is isolated and its actuator is currently removed for maintenance. 1KFP-5130, Spent Fuel Pool Temperature, failed last shift (IAE is investigating) and MCB Annunciator 1AD-1, F-9, DEH/MSR SYSTEM MALFUNCT, has failed to OFF (IAE is investigating).

Shortly after taking the watch, the Turbine Driven CA Pump will inadvertently start causing the plant to cooldown and reactor power to rise. The crew will recognize that the pump should not be running and stop the pump using OP/1/A/6250/002, Auxiliary Feedwater System. The operator may use AP/1/A/5500/1, Steam Leak, to diagnose the failure. The operator will address Technical Specification 3.7.5, Auxiliary Feedwater (AFW) System, and SLC 16.9.7, Standby Shutdown System.

Next, the 1B SG FRV Controller will fail to MANUAL and the FRV Bypass valve will fail fully open resulting in the Feedwater Control Valve for the 1B SG closing and causing SG Level to lower.

The operator will respond in accordance with AP/1/A/5500/06, S/G Feedwater Malfunction, and control the 1B SG Level manually.

Following this, a 70-90 gpm leak will develop on the reactor head from a Control Rod Guide Tube.

The crew will implement AP/1/A/5500/10, NC System Leakage Within the Capacity of Both NV Pumps. The operator will address Technical Specification 3.4.13, RCS Operational Leakage.

During the downpower, a failure will occur in the Turbine Control Unit causing the unit to shift from Operator Auto to Manual control. The operator will address 1AD-1/F-4, TURBINE IN MANUAL, and control the Turbine manually during the downpower in accordance with OP/1/A/6300/001A, .1, Turbine Generator Load Change.

After this, Control Rod D-4 will be ejected from the core causing a 1000 gpm Small Break LOCA.

The operator will trip the Reactor and actuate Safety Injection, and then enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection. On the Safety Injection actuation the EDG B Sequencer will fail to automatically sequence, and the operator will need to manually start ECCS loads.

Additionally, the 1A NV Pump will trip, and the 1A NI Pump will fail to start automatically. The operator will be required to start the 1A NI Pump manually.

Upon completion of E-0, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant. At that time a second Control Rod (F-14) will be ejected from the core causing the Small Break LOCA to degrade to the point at which the NC Pumps will need to be tripped. The scenario will terminate at Step 9 of E-1, after the crew has been directed to return back to the beginning of E-1.

Critical Tasks:

Establish flow from at least one high-head ECCS Pump before transition out of E-0.

Safety Significance: Failure to establish flow from the NV System after failure of the automatic actuation constitutes a demonstrated inability by the operator to recognize a failure and/or correct a failure of an ESF System or component. The FSAR analyses of response to high energy line breaks assume that at least one train of safeguards actuates. If the minimum assumed ESF components are NOT actuated the Safety Scenario Event Description NRC Scenario 5 Analyses results are invalid. Because compliance with the assumptions in the FSAR is part of the facility license, failure to comply constitutes a violation of the license condition.

Trip NC Pumps within 5 minutes of loss of SCM (4600/113/E13.1)

Safety Significance: Failure to trip all NCPs on a loss of subcooled margin can lead to core uncovery and to fuel temperatures in excess of 2200oF. PT/0/A/4600/113, Enclosure 13.1 states that McGuire is committed to having NC Pumps tripped within 5 minutes of a loss of subcooling.

The Safety Analysis recommends that the NC Pumps be tripped within 2 minutes to limit the depth and duration of core uncovery. It is a management expectation that the NC Pumps be tripped as quickly as possible, but within 5 minutes of a loss of subcooling. Failure to take this action represents mis-operation by the operator which leads to degradation of the fuel cladding fission produce barrier, and a violation of a license condition.

Rod Ejection/SB LOCA/1B NV Pump Trip/EDG A Sequencer Failure/1B NI Pump fails to Start in AUTO/2nd Rod Ejection/SB LOCA After this, Control Rod D-4 will be ejected from the core causing a 1000 gpm Small Break LOCA. The operator will trip the Reactor and actuate Safety Injection, and then enter EP/1/A/5000/E-0, Reactor Trip or Safety Injection. On the Safety Injection actuation the EDG A Sequencer will fail to automatically sequence, and the operator will need to manually start ECCS loads. Additionally, the 1B NV Pump will trip, and the 1B NI Pump will fail to start automatically. The operator will be required to start the 1B NI Pump manually. Upon completion of E-0, the operator will transition to EP/1/A/5000/E-1, Loss of Reactor or Secondary Coolant. At that time a second Control Rod (F-14) will be ejected from the core causing the Small Break LOCA to degrade to the point at which the NC Pumps will need to be tripped.

• Perform the following on energized train(s):

• Check OAC Monitor Light Program ("MONL") for Group 6 windows that are dark.

• Align valves as required, while continuing in this EP.

Critical Task:

Establish flow from at least one high-head ECCS Pump before transition out of E-0.

Safety Significance: Failure to establish flow from the NV System after failure of the automatic actuation constitutes a demonstrated inability by the operator to recognize a failure and/or correct a failure of an ESF System or component. The FSAR analyses of response to high energy line breaks assume that at least one train of safeguards actuates. If the minimum assumed ESF components are NOT actuated the Safety Analyses results are invalid.

Because compliance with the assumptions in the FSAR is part of the facility license, failure to comply constitutes a violation of the license condition.

• Notify RP to perform the following: NOTE: The CRS may call WCC/RP to address the switch position.

If so, Booth Instructor acknowledge as WCC/RP.

• Frisk all Unit 1 S/G cation columns to determine if activity level is significantly higher for any S/G.

• Notify Control Room of survey results.

CRS

• WHEN survey results reported, THEN NOTE: This is a Continuous perform the following: Action. The CRS will make both board operators aware.

• Check all S/G(s) activity levels -

NORMAL.

BOP

• Check secondary EMFs - NORMAL:

• 1EMF-33 (Condenser Air Ejector Exhaust)

• 1EMF-34(L) (S/G Sample (Lo Range))

• 1EMF-24 (S/G A)

• 1EMF-25 (S/G B)

• 1EMF-26 (S/G C)

• 1EMF-27 (S/G D).

BOP (Step 6) Check Pzr PORVs and isolation valves:

• Power to all Pzr PORV isolation valves -

AVAILABLE.

• All Pzr PORVs - CLOSED.

• At least one Pzr PORV isolation valve -

OPEN.

• IF AT ANY TIME any Pzr PORV opens NOTE: This is a Continuous due to high pressure, THEN after Action. The CRS will make pressure goes below 2315 PSIG, ensure both board operators aware.

Description:

Rod Ejection/SB LOCA/1B NV Pump Trip/EDG A Sequencer Failure/1B NI Pump fails to Start in AUTO/2nd Rod Ejection/SB LOCA Time Pos. Expected Actions/Behavior Comments RO/ (Step 7) Check S/I termination criteria:

BOP

• NC subcooling based on core exit T/Cs - NOTE: The NCS is NOT GREATER THAN 0°F. subcooled.

Critical Task:

Trip NC Pumps within 5 minutes of loss of SCM (4600/113/E13.1)

Safety Significance: Failure to trip all NCPs on a loss of subcooled margin can lead to core uncovery and to fuel temperatures in excess of 2200oF. PT/0/A/4600/113, 3.1 states that McGuire is committed to having NC Pumps tripped within 5 minutes of a loss of subcooling. The Safety Analysis recommends that the NC Pumps be tripped within 2 minutes to limit the depth and duration of core uncovery. It is a management expectation that the NC Pumps be tripped as quickly as possible, but within 5 minutes of a loss of subcooling. Failure to take this action represents mis-operation by the operator which leads to degradation of the fuel cladding fission produce barrier, and a violation of a license condition.

Record Pump Stop Time: __________

subtract time recorded at time of the loss SCM on page 49 _____ = _____ minutes.

BOP (Step 7.a RNO) GO TO Step 7.f.

RO/

• Monitor S/I termination criteria PER BOP Enclosure 2 (S/I Termination Criteria) while in the procedure.

• IF AT ANY TIME while in this procedure NOTE: This is a Continuous S/I termination criteria is met, THEN Action. The CRS will make RETURN TO Step 7. both board operators aware.

BOP (Step 8) Check if ND pump should be stopped:

• NC pressure - GREATER THAN 275 NOTE: The ND Pumps are PSIG. both ON.

• NC pressure - STABLE OR GOING UP. NOTE: The NCS pressure is likely rising at this time.

• Any ND pump ON.

• Running ND pumps suction ALIGNED TO FWST.

• Reset the following:

• S/I.

• Sequencers.

• Stop ND pumps.

• IF AT ANY TIME a B/O signal occurs, NOTE: This is a Continuous THEN restart S/I equipment previously Action. The CRS will make on. both board operators aware.

• IF AT ANY TIME NC pressure goes NOTE: This is a Continuous below 275 PSIG in an uncontrolled Action. The CRS will make manner, THEN restart ND pumps. both board operators aware.

BOP (Step 9) Check NC and S/G pressures:

• All S/G pressure - STABLE OR GOING UP.

• NC pressure - STABLE OR GOING NOTE: The NCS pressure is DOWN. likely rising at this point, and the CRS will return to Step 1.

At the discretion of the Lead Examiner terminate the exam.
