The scenario begins at approximately 50-55% power. Containment Spray pump 112 and Reactor Building Exhaust Fan 12 are out of service for maintenance.

Circulating Water pump 11 is out of service following maintenance.

The crew will start Circulating Water pump 11, then raise Reactor power with recirculation flow. Then, Recirculation flow unit 11 fails upscale. The crew will respond per the alarm response procedure and the CRS will determine the Tech Spec impact. Then, an inadvertent EC initiation occurs. The crew will respond to isolate the EC and the CRS will determine the Tech Spec impact. Next, fuel failure will occur due to the previous transients.

The crew will respond per N1-SOP-25.2, Fuel Failure or High Activity in Rx Coolant or Off-Gas. This includes performing an emergency power reduction per N1-SOP-1.1, and eventually scramming the Reactor per N 1-SOP-1 (Critical Task). When the Generator trips after the scram, Powerboard 12 will fail to transfer to reserve power. The crew will execute N1-SOP-30.2, Loss of Powerboard 12, to re-energize the powerboard.

Feedwater Pump 11 will trip shortly after the reactor scram. Following the scram, a Main Steam line break will occur. The MSIVs will fail to close both automatically and manually, leading to an un-isolable leak into the Turbine Building.

The running Turbine Building ventilation exhaust fan will trip. The crew will start the standby Turbine Building ventilation exhaust fan, however it will trip after a short time delay. This will allow an un-monitored, ground level release from the Turbine Building.

The crew will enter N1-EOP-6, Radioactivity Release Control. Field reports will indicate off-site release rates approaching the General Emergency level. The crew will perform an RPV Slowdown per N1-EOP-8 (Critical Task). 1. Termination Criteria a. RPV water level controlled in assigned band, RPV Slowdown in progress Page 3 of 23 NRC Scenario 2 March 2015 Exelon Generation

2. Critical Tasks CT-1, Given fuel failure causing Main Steam Line radiation levels to approach and/or exceed 3.75 times normal full power background, scram the Reactor, in accordance with N1-SOP-25.2.

Justification:

Safety Significance:

High Main Steam Line radiation levels indicate fuel failure and release of fission products to the Reactor coolant. A Reactor scram reduces the rate of energy production and thus the heat input, radioactivity release, and flow down the Main Steam Lines. Scramming the Reactor also allows further mitigating actions, such as Reactor isolation and depressurization.

Cueing: Multiple annunciators and radiation monitors will provide indications of fuel failure. N1-SOP-25.2 directs scramming the Reactor. Measurable Performance Indicators:

Rotation of the Mode Switch to SHUTDOWN or depressing the manual scram pushbuttons will provide observable actions for the evaluation team. Performance Feedback:

Control rod position and Reactor power indications will provide performance feedback regarding the success of the scram. CT-2, Given an un-isolable primary system discharging outside of primary and secondary containments and off-site release rate approaching the General Emergency level, perform an RPV Slowdown, in accordance with N1-EOP-6.

Justification:

Safety Significance:

An un-isolable primary system discharging outside of Primary and Secondary Containments resulting in off-site release rates approaching the General Emergency limit indicates a significant problem posing a direct and immediate threat to the health and safety of the public. A blowdown minimizes flow through the break, rejects heat to the suppression pool in preference to outside the containment, and places the primary system in the lowest possible energy state. This will lower the release of radioactivity to the environment and lower the dose received by the public. Cueing: Multiple annunciators will provide indications of a primary system discharging into the Turbine Building.

MSIV valve position indicators will provide indication that the system is un-isolable.

Field reports will provide indication that site release rate approaches the General Emergency level. N1-EOP-6 provides direction to blowdown the Reactor. Measurable Performance Indicators:

The crew will manually initiate Emergency Condensers and open ERVs. Performance Feedback:

Emergency Condenser and ERV instrumentation will provide indication that these systems are functioning properly once placed in service. Multiple Reactor pressure indicators and annunciators will provide performance feedback regarding the success of the blowdown.

11. Unit 1 Technical Specifications Page 2 of 28 NRC Scenario 3 March 2015 Exelon Generation Instructor Information A. Scenario Description Sequence of Events I Expected Crew Response:

The crew assumes the shift at approximately 85% power. Containment Spray pump 112 and Reactor Building Exhaust Fan 12 are out of service for maintenance.

The crew is directed to remove Condensate Pump 11 from service immediately for maintenance due to a motor oil leak. After the pump has been removed from service, the crew will conduct a rod pattern exchange.

During the rod pattern exchange, a Main Steam Line Rad monitor will fail inoperable.

The SRO will address Tech Specs. Next, the Reactor Building Closed Loop Cooling (RBCLC) Temperature Controller will fail such that RBCLC temperatures rise. This failure will require placing the RBCLC controller in manual and restoring the effected equipment to normal temperatures.

Then, RPS MG set 141 will trip. The crew will enter SOP-16.1 due to the resulting partial loss of Feedwater heating. The crew must recover the RPS trip bus by shifting to its alternate supply. Next, an Instrument Air leak will occur in the piping to the CRD system. The crew will insert a manual Reactor scram as CRD air pressure lowers below 60 psig (Critical Task). When the scram occurs the control rods will not fully insert. The crew must terminate and prevent injection (Critical Task). When the operator attempts to close Feedwater Isolation Valves 11 and 12, the valves will fail to isolate Feedwater flow. The crew must diagnose the failure and place the Feedwater pumps in Pull-To-Lock to terminate feeding the RPV. The crew will lower Reactor power by inserting control rods per EOP-3.1 and/or using Liquid Poison (Critical Task). 1. Termination Criteria a. RPV water level controlled in assigned band, Reactor power< 6%, Control rod insertion in progress or complete Page 3 of 28 NRC Scenario 3 March 2015 Exelon Generation

2. Critical Tasks CT-1, Given lowering CRD system air pressure, the crew will insert a manual reactor scram before control rods begin drifting, in accordance with N1-ARP-F3 and/or N1-SOP-20.1.

Justification:

Safety Significance:

Lowering CRD system air pressure can result in various rods drifting to unpredictable locations in the core. This can lead to an unanalyzed rod pattern and localized power peaking resulting in fuel damage. Cueing: Annunciators on L 1 and F3 will provide indication for lowering plant air pressures.

Procedures direct inserting a manual reactor scram for lowering CRD system air pressure.

Measurable Performance Indicators:

Inserting a manual reactor scram will provide observable actions for the evaluation team Performance Feedback:

Control rod position and Reactor power will provide performance feedback regarding success of crew actions to insert control rods. Page 4 of 28 NRC Scenario 3 March 2015 Exelon Generation CT-2, Given a failure of the reactor to scram with power above 6% and RPV water level above -41 inches, the crew will terminate and prevent all injection except boron and CRD, in accordance with N1-EOP-3. Justification:

Safety Significance:

High Reactor power after a scram represents a challenge to nuclear fuel and to plant heat sinks. In the event of a loss of the nonnal heat sink, this may result in adding heat to the Torus and challenging the Primary Containment.

Lowering Reactor power reduces these challenges.

Cueing: Control rod position and Reactor power indications will indicate a failure to scram with Reactor power above 6%. N1-EOP-3 provides direction to trip Recirculation pumps and tenninate and prevent injection based on Reactor power. Measurable Performance Indicators:

Manipulation of Recirculation pump control switches, Feedwater system components, and Core Spray jumpers will provide observable actions for the evaluation team. Performance Feedback:

Lowering Recirculation flow, Feedwater flow, Reactor water level, and Reactor power will provide perfonnance feedback regarding the success of crew actions. CT-3, Given a failure of the reactor to scram with power above 6%, the crew will lower reactor power by inserting control rods or injecting boron, in accordance with N1-EOP-3.

Justification:

Safety Significance:

Inserting control rods lowers Reactor power, which reduces challenges to the plant during a failure to scram. Additionally, inserting control rods ultimately provides a long-tenn, stable core shutdown.

Boron injection will lower power, however, alone may not provide a stable shutdown condition.

Cueing: Control rod position and Reactor power indications will indicate a failure to scram. N1-EOP-3 provides direction to insert control rods. Measurable Performance Indicators:

Manipulation of RPS, CRD, and RMCS controls will provide observable actions for the evaluation team. Performance Feedback:

Control rod position and Reactor power will provide perfonnance feedback regarding success of crew actions to lower power by inserting control rods or injecting Boron. Page S of 28 NRC Scenario 3 March 2015 Exelon Generation

Scenario Description Sequence of Events I Expected Crew Response:

The crew assumes the shift with the plant operating at 90% power and four recirculation loops in service. Containment Spray pump 112 and Reactor Building Exhaust Fan 12 are out of service for maintenance.

Immediately after assuming the shift the crew will be directed to restore Recirculation Pump 11 to service and return to full power. The crew will assess plant conditions and lower power with Recirculation Flow until flow is less than 50 Mlbm/hr. They will then return Recirculation Pump 11 to service. After the crew has placed the recirc pump in service, #11 RB exhaust fan will trip. The crew will diagnose the fan trip and a positive RB pressure.

With #12 RB exhaust fan OOS, the crew will start the Reactor Building Emergency Ventilation System (RBEVS) to restore a negative RB pressure.

Entry into N1-EOP-5, Secondary Containment Control is required.

SRO determines the secondary containment TS is still satisfied.

Next, RRP 15 flow rises due to a blind controller failure. The crew will take the M/A station to manual, and the rise will stop. RRMG 15 will develop a high slot temperature, requiring the crew to remove it from service. A steam leak will then develop in the Primary Containment.

The crew will insert a scram. Following the scram, HPCI will fail to initiate, requiring manual action to establish injection with preferred and/or alternate injection systems to maintain RPV water level (Critical Task). When the crew attempts to spray the Containment, Containment Spray pump 111 will trip. The two remaining Containment Spray pumps will be insufficient to avoid violating PSP, and the crew will perform an RPV Slowdown (Critical Task). 1. Termination Criteria a. RPV water level controlled in assigned band, RPV Slowdown in progress, Primary Containment pressure controlled per N1-EOP-1 attachment 17 Page 3 of 25 NRC Scenario 4 March 2015 Exelon Generation

2. Critical Tasks CT-1, Given a LOCA in the Drywell and a failure of HPCI to initiate, the crew will inject with preferred and alternate injection systems to restore and maintain RPV water level above -84 inches, in accordance with N1-EOP-2 Justification:

Safety Significance:

Maintaining Reactor water level above -84 inches ensures adequate core cooling through the preferred method of core submergence.

This protects the integrity of the fuel cladding.

Cueing: Multiple Reactor water level indicators and annunciators will provide indications of lowering Reactor water level. N1-EOP-2 provides multiple procedure steps directing injection with preferred and alternate injection systems. Measurable Performance Indicators:

Manipulation of pumps and/or valves in the preferred or alternate injection system(s) will provide observable actions for the evaluation team. Performance Feedback:

Multiple Reactor water level indicators and annunciators will provide perfonnance feedback regarding the success of injection with preferred and alternate injection systems. CT-2, Given a LOCA in the Drywell and degraded Containment Spray capability, the crew will execute N1-EOP-8, RPV Slowdown, when it is determined Torus pressure cannot be maintained below the Pressure Suppression Pressure limit, in accordance with N1-EOP-4.

Justification:

Safety Significance:

A Blowdown is required to limit further release of energy into the Primary Containment and to ensure that the RPV is depressurized while pressure suppression capability is still available.

This protects the integrity of the Primary Containment.

Cueing: Multiple Primary Containment pressure indicators and annunciators will provide indications.

N1-EOP-4 provides direction to monitor the Pressure Suppression Pressure limit and blowdown if required.

Measurable Performance Indicators:

The crew will manually open valves to initiate Emergency Condensers.

The crew will manually open ERVs. Performance Feedback:

Emergency Condenser and ERV instrumentation will provide indication that these systems are functioning properly once placed in service. Multiple Reactor pressure indicators and annunciators will provide perfonnance feedback regarding the success of the blowdown.

The scenario begins at approximately 100% power. Containment Spray pump 112 and Reactor Building Exhaust Fan 12 are out of service for maintenance.

The crew will remove Line 4 from service for maintenance.

The CRS will determine the Tech Spec impact. Next, ERV 111 will inadvertently open. The crew will enter N1-SOP-1.4, Stuck Open ERV. The crew will perform an emergency power reduction to approximately 85% power, then take actions to close ERV 111 (Critical Task). These actions will close the ERV, but leave it inoperable.

The CRS will determine the Tech Spec impact. Next, Powerboard 16A will develop an electrical fault. This will cause a loss of power to three Drywell cooling fans. The crew will start an additional Drywell cooling fan to stabilize Drywell temperature and pressure.

The electrical loss will also affect EDG 103 auxiliary equipment.

The CRS will determine the Tech Spec impact. Next, the running RBCLC pumps will trip. The standby RBCLC pump will trip upon being started. The crew will enter N1-SOP-11.1, RBCLC Failure. The crew will scram the Reactor, trip Recirculation pumps, initiate Emergency Condensers, and shut the MSIVs. The high pressure Feedwater pumps will trip on the scram, complicating Reactor water level control. Once the crew stabilizes the plant after the scram, a coolant leak will develop inside the Primary Containment.

The crew will re-enter N1-EOP-2, RPV Control, and N1-EOP-4, Primary Containment Control. Containment parameters will degrade and the crew will initiate Containment Sprays (Critical Task). The elevated Containment temperature will cause the Fuel Zone level indications to become erratic. With all other Reactor water level indicators downscale, the crew will execute N1-EOP-7, RPV Flooding, to lower Reactor pressure and flood the Reactor to the Main Steam lines (Critical Task). 1. Termination Criteria a. RPV Flooding in progress b. Reactor water level on scale or upscale c. Containment pressure and temperature controlled in accordance with N1-EOP-4 Page 3 of 25 NRC Scenario 5 March 2015 Exelon Generation

2. Critical Tasks CT-1, Given an inadvertently open ERV at power, close the ERV or insert a manual scram prior to Torus temperature exceeding 110°F, in accordance with N1-SOP-1.4 Justification:

Safety Significance:

A manual Reactor scram is required before Torus temperature exceeds 11 D°F. This reduces the rate of energy production and thus heat input to the Torus. Additionally, this allows evaluating the success of the Reactor scram before boron injection would be required due to Torus temperature in the event of a failure to scram. Closing the ERV prior to the need for the scram avoids the need for these more substantial actions, prevents challenging the plant with a scram, and stops heat input to the Torus. Cueing: ERV position, ERV acoustic monitors, ERV tailpipe temperature, Torus temperature, Reactor pressure, and steam flow indicate an open ERV. N1-SOP-1.4 provides direction to close the ERV or scram the Reactor. Measurable Performance Indicators:

Pulling ERV fuses, directing an operator to pull ERV fuses in the field, rotating the Mode Switch to SHUTDOWN, and/or depressing the manual scram pushbuttons will provide observable actions for the evaluation team. Performance Feedback:

ERV position, ERV acoustic monitors, ERV tailpipe temperature, Torus temperature, Reactor pressure, and steam flow will provide perfonnance feedback regarding success of crew actions to close the ERV. Control rod position and Reactor power will provide perfonnance feedback regarding success of crew actions to scram the Reactor. Page 4 of 25 NRC Scenario 5 March 2015 Exelon Generation@

CT-2, Given a LOCA in the Drywell, initiate Containment Sprays prior to exceeding the Pressure Suppression Pressure limit, in accordance with N1-EOP-4 Justification:

Safety Significance:

Initiating Containment Sprays reduces Primary Containment pressure.

This reduces stresses on the Drywell and Torus, assists in avoiding "chugging" that may cause fatigue failure of the LOCA downcomers, and avoids the need for a blowdown.

These benefits reduce challenges to the fuel cladding, the RPV, and the Primary Containment.

Cueing: Multiple Primary Containment pressure and temperature indications and annunciators will indicate degrading conditions.

N1-EOP-4 provides direction to initiate Containment Sprays. Measurable Performance Indicators:

Manipulation of Containment Spray pump control switches will provide observable actions for the evaluation team. Performance Feedback:

Containment Spray flow and lowering Primary Containment pressure and temperature indications will provide performance feedback regarding success of crew actions to initiate Containment Sprays. CT-3, Given the plant with RPV water level unknown, execute N1-EOP-7, RPV Flooding, in accordance with N1-EOP-2.

Justification:

Safety Significance:

With Reactor water level unknown, the status of core cooling is unknown. RPV flooding is required to establish conditions to cool the core. This protects the fuel cladding integrity.

Cueing: Multiple Reactor water level indications will indicate either downscale or invalid. N1-EOP-2 provides direction to implement N1-EOP-7, RPV Flooding.

Measurable Performance Indicators:

Manipulation of ERVs, MS/Vs, EC/Vs, and injection system controls provide observable actions for the evaluation team. Performance Feedback:

ERV, MSIV, and ECIV position indications, Reactor pressure, ERV tailpipe temperatures, and ERV acoustic monitors provide performance feedback regarding success of RPV flooding actions. 3. Length a. -60 minutes Page 5 of 25 NRC Scenario 5 March 2015 Exelon Generation
