The following equipment is Out-Of-Service: The B CNMT Spray Pump has been declared INOPERABLE due to excessive inboard vertical vibration during STP-0 COMP-B surveillance test yesterday. Engineering is evaluating the data. A-52.4 submitted for ITS 3.6.6, 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Action.

Shortly after taking the watch, a CCW System Supply Relief Valve will lift and fail to reseat causing a 30 gpm CCW System leak. Approximately two minutes afterwards the B CCW Pump will trip, and the B CCW Pump will automatically start. The operator will respond in accordance with AR-A-17, MOTOR OFF RCP CCWP, and enter AP-CCW.2, Loss of CCW During Power Operation. The operator will address Te:lchnical Specification 3.7.7, Component Cooling Water System.

After this, Pressurizer Level Channel 427 will fail LOW, resulting in letdown isolation and de-energizing the pressurizer heaters. The crew will n::lspond per AR-F-11, PZR LOW LEVEL 13%, and ER-INST.1, Reactor Protection Bista1ble Defeat After lnstrumi::lntation Loop Failure. They will defeat the failed channel, reset PZR heaters, reduce charging to a single charging pump, and re-establish letdown per S-3.2.E, Placing In or Removing From Service Normal Letdown/Excess Letdown. The crew will start a second charging pump and slowly restore PZR level to program (52%). The operator will address Technical Specification 3.3.1, Reactor Trip System {RTS) Instrumentation and 3.4.9, Pressurizer.

Then, turbine control valve CVL-4 will drift closed. The crew will respond per AP-TURB.2, Turbine Load Rejection, begin a load reduction to less than 50% powE::lr using AP-TURB.5, Rapid Load Reduction.

During the load reduction, a failure of the B FRV to control in AUTO. The operator will respond per AR-G-5, SIG/ B LEVEL DEVIATION +/-7%, or upon observing an abnormally high level in the B Steam Generator and control the B FRV manually. The operator will address Technical Specification 3.7.3, Main Feedwater Isolation Valves (MFIVs), Main Feedwater Regulating Valves (MFRVs ), and Associated Bypass Valves.

Subsequently, a major steamline break will occur in the! Turbine Building downstream of the MSIVs. Both MSIVs will fail to close automatically in response to manual attempts from the MCB. The reactor will fail to trip automatically and manual pushbutton will not work, requiring opening of normal supply breakers for Bus 13 and Bus 15 to de-energize rod drive MG sets to trip the reactor. The crew will enter E-0, Reactor Trip or Safety Injection.

The crew will ultimately transition to E-2, Faulted SIG Isolation. Since both MSIVs are failed open, and with a downstream break, both SGs will be affected and their pressures will lower concurrently. Eventually, the crew will transition to ECA-2.1, Uncontrolled Depressurization of Both Steam Generators. After the operator throttles AFW flow in ECA-2.1, the leak will increase in magnitude, resulting in an Orange Path on RCS Appendix D Scenario Outline Form ES-D-1 Draft (110414)

Integrity. Simultaneously the event will be complicated by a Loss of Offsite Powe,r. Both Emergency Diesel Generators will start and automatically repower the respective Emergency Susses, and the operator will need to re-establish AFW flow of 50 gpm to each Steam Generator.

The crew will implement FR-P.1, Response to Imminent Pressurized Thermal! Shock Condition, when RCS cold leg temperatures reach 311°F. In FR-P.1 the crew will stop the SI pumps and the RHR pumps.

The scenario will be terminated after the SI and RHR pumps are secured.

Critical Tasks:

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

Additionally, it constitutes an "incorrect performance that necessitates the crew taking action which complicates the event mitigation strategy that demonstrates the inability by the crew to recognize a failure of the automatic actuation of the RPS.

2. Control the AFW flowrate to 50 gpm per SG iin order to minimize the RCS Cooldown rate Safety Significance: Failure to control the AFW flow rate to the SGs when able to do so causes a challenge to the subcriticality and RCS Integrity CSFs beyond that irreparably introduced by the postulated conditions. Additionailly, it constitutes an "incorrect performance that may necessitate the crew taking action which complicates the event mitigation strategy (Transition to FR-S.1 on inability to maintain a negative SUR).

The operator will need to lower the Turbine Load to stabilize the vibrations. During the load reduction Hotwell Level Transmitter will fail HIGH. The operator will need to manually control the Hotwell Level Controller.

Subsequently, a feed line rupture inside Containment will occur. The Reactor will trip however, the Turbine will fail to trip automatically and Safety Injection will fail to actuate automatically. The operator will enter E-0, Reactor Trip or Safety Injection. On the reactor trip the A AFW Pump will fail to Autostart, then trip after it is manually started; and the TDAFW Pump will trip on overspeed. The operator will transition from E-0 to FR-H.1, Response to a Loss of Secondary Heat Sink.

Appendix D Scenario Outline Form ES-D-1 Draft (110414)

The operator will unsuccessfully attempt to place the Standby AFW System in service, and then attempt to restore a Secondary Heat Sink using the MFW System. Once the Secondary Heat Sink is re-established using MFW, the operator will transition back to E-0, and then transition to E-2, Faulted Steam Generator Isolation.

The scenario will terminate at Step 9 of E-2, after the crew has determined that a transition to E-1, Loss of Reactor or Secondary Coolant, is required.

Critical Tasks:

1. Manually actuate Safety Injection before transition out of E-0 into ES-0.1 Safety Significance: Failure to actuate Safety Injection when it is required to be actuated, and can be actuated, violates the assumptions of the Safety Analysis and constitutes incorrect performance that could lead to misdiagnosis of the event, implementation of an incorrect mitigation strategy and ultimately degradation of the RCS and/or fuel cladding fission product barriers.
2. Establish feedwater flow into at least one Steam Generator before RCS Bleed and Feed is required.

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 initiate 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.

Ginna 2014 NRC Scenario #4 The plant is at 48% power (MOL). Power has been held at this level for approximately four days while corrective maintenance is performed on the A MFW Pump. Maintenance has just been completed. Chemistry has requested that Letdown flow be raised from 40 gpm to 60 gpm. Also, it is expected to swap El-IC Pumps per P-17 for routine equipment rotation.

The following equipment is Out-Of-Service: The B AFW Pump is OOS for Bearing Replacement. Steam Flow channel FT-475 is OOS. The channel has been defeated per ER-INST.1.

Shortly after taking the watch, the operator will swap Letdown Orifice Control valves in accordance with S-3.2P, Swapping CVCS Letdown Orifices.

After this, the operator will alternate the EHC Supply Pump alignment in accordance with P-17, Operations Control Room Operating Instructions, Attachment 12, CROl-12 Swapping Electro-Hydraulic Pumps.

Then, the N41 Power Ranger Upper Detector will fail Low. The operator will respond in accordance with AR-E-26, POWER RANGE CHANNEL DEV +/-2%, and/or AR-E-28, POWER RANGE ROD DROP ROD STOP -5%/5SEC, and then enter ER-NIS.3, PR Malfunction. The operator will address Technical Specification 3.3.1, Reactor Trip Instrumentation. While the CO is defeating the failed Power Range Channel, a failure of the Letdown Pressure Controller will cause PCV-135 to fail OPEN. The operator will need to take manual control of the failed controller,. and control Letdown pressure manually.

Subsequently, Pressurizer PORV-431 C will fail partially open. The operator will respond in accordance with AR-F-18, PRZR PORV OUTLET HI TEMP 145°F, and enter AP-PZR.1, Abnormal Pressurizer Pressure. When the operator attempts to isolate the PORV, the Block Valve will fail to shut fully resulting in a 2-5 gpm leak into the PRT. The crew may implement AP-RCS.1, Reactor Coolant Leak, and prepare to make a Containment entry. Ultimately, the crew will be directed to take the unit off-line. The operator will address Technical Specification 3.4.11, Pressurizer PORVs, 3.4.1 RCS Pressure, Temperature, and Flow Departure from NuclE:~ate Boiling (DNB) Limits, as well as TRM 3.4.3, Anticipated Transients Without Scram (ATWS) Mitigation. Although the crew will address Technical Specification 3.4.13, RCS Leakage, it is likely that at the current leakrate, this specification will be met.

The operator will take the unit off line in accordance with AP-TURB.5, Rapid Load Reduction During the downpower, the Main Turbine will fail in automatic control, and shift to manual control. The operator will identify that the load reduction has been stopped, and use manual control of the turbine to restart and continue the downpower.

The remainder of the downpower will need to be accomplished using manual control of the Turbine.

When the plant is at approximately 40% power, the piping leading to the failed PORV will fail so that a vapor space Small Break LOCA occurs. The plant will trip and Safety Appendix D Scenario Outline Form ES-D-1 Draft (110714)

Injection will be actuated, and the operator will entE~r E-0, Reactor Trip or Safety Injection. On the plant trip Containment Isolation Valve MOV-313, the Seal Water Return Line CIV, will fail to close automatically, requiring that the operator manually close this valve.

The operator will transition from E-0 to E-1, Loss of Reactor or Secondary Coolant, and then into ES-1.2 Post-LOCA Cooldown and Depressurization. While in ES-1.2, an Orange Path may occur on the RCS Integrity Critical Safety Function Status Tree.

The scenario will terminate at Step 14 of ES-1.2, after the crew has demonstrated the ability to evaluate/perform the SI flow reduction sequence, or upon transition to FR-P.1, Response to Imminent Pressurized Thermal Shock Condition.

Critical Tasks:

1. Trip all RCPs within 5 minutes of reaching trip criteria Safety Significance: Failure to trip all RCPs when required can lead to core uncovery and to fuel temperatures in excess of 2200°F. Analys1as have shown that if the RCPs are tripped within 5 minutes of the trip criteria being met, PCT will remain below 2200 °F, and if this action is delayed beyond 5 minutes, this PCT will be exceeded. It is a management expectation that the RCPs be tripped as quickly as possible, but within 5 minutes when the trip criteria is met. 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.
2. Close the Seal Water Return Containment Isolation Valve before transition out of E-0.

Safety Significance: Failure to close at least one Containment Isolation Valve on each critical penetration under the postulated conditions when it is possible to do so, constitutes mis-operation leading to degradation of the Containment Barrier. Failure to take this action leads to an unnecessary release of fission products to the auxiliary building, increasing the potential for release to tile environment, and reducing accessibility to vital equipment within the Auxiliary Building. Higher radiation levels within the Auxiliary Building will result in a degradation of ALARA principles.

Ginna 2014 NRC Scenario #5 The plant is at 1 x 10-8 amps (BOL). The plant ran at 100% power for 12 days, and then tripped four days ago due to a MFW Pump failure. The repairs have been made and the plant is ready to be started back up. The crew will be directed to pull rods to the point of adding heat (POAH), and start the B MFW Pump in accordance with 0-1.2, Plant Startup From Hot Shutdown to Full Power Load, Step 6.3.4 and beyond. The area has experienced thunderstorms over the last 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and this is expected to continue for the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

The following equipment is Out-Of-Service: The B Condensate Pump is OOS for Bearing Replacement.

Shortly after taking the watch, the operator will raise power to the POAH in accordance with Step 6.3.4 of 0-1.2, Plant Startup From Hot Shutdown to Full Load. The operator will raise reactor power and stabilize reactor power at 0.5-1.0%; and then control Tavg at 547°F.

After this, the operator will conduct the oil pump checks on the A Main Feedwater (MFW)

Pump accordance with Attachment 5, Main Feed Pump A Startup of 0-1.2, Plant Startup From Hot Shutdown to Full Load, in preparation for starting the A MFW Pump.

Subsequently, a 480VAC ground will occur on Bus 14 and the A CCW Pump will trip, and the B CCW Pump will fail to automatically start. The operator will either start the A CCW pump manually per A-503.1, Emergency and Abnormal Operating Procedures Users Guide; or respond in accordance with AR-A-22:, CCW PUMP DISCHARGE LO PRESS 60 PSI, and enter AP-CCW.2, Loss of CCW During Power Operation. The operator will evaluate Technical Specification 3.7.7, CCW System.

Shortly after this, a fault on 480V Bus 18 will occur, resulting in Bus 18 de-ene~rgizing.

The operator will respond in accordance with AR-L**23, BUS18 UNDER VOLTAGE SAFEGUARDS and/or AR-L-5, SAFEGUARD BUS MAIN BREAKER OVERCURRENT TRIP and enter AP-ELECT.17/18, Loss of Safeguards Bus 17/18. The D Service Water Pump has failed to start, leaving only the B SW Pump running. The operator may leave the A EOG running or trip it within AP-ELECT.17 /18, but in either case align Alternate Cooling to the EOG. The operator will enter AP-SW.2, Loss of Service Water, and take actions to isolate non-essential SW loads. The operator will address TBchnical Specification 3.8.1, AC Sources - Modes 1, 2, 3, and 4; 3.8.9, Distribution Systems -

Modes 1, 2, 3,and 4; and 3.7.8, Service Water System.

During the recovery, Letdown Pressure Control Valve PCV-135 will fail closed causing the Letdown Line Relief valve to lift to the PRT. The operator will respond in accordance with AR-A-11, LETDOWN LINE HI PRESS 400 PSI, and take manual control of the valve.

Shortly afterwards, the compensating voltage power supply for the Intermediate~ Range Nuclear Instrument N35 will fail Low. The operator will respond in accordance with AR-E-9, IR N-35 LOSS OF COMPENSATING VOLTAGE and enter ER-NIS.2, IR MALFUNTION. The operator will address Technical Specification 3.3.1, Reactor Trip Instrumentation.

Appendix D Scenario Outlirn:~ Form ES-D-1 Draft (110414)

After this, the B ARV will inadvertently close, and one SG Safety valve will open and stick open. The reactor will fail to trip automatically, and the operator will need to manually trip the reactor and enter E-0, Reactor Trip or Safety Injection. On the trip approximately 1% failed fuel will occur. The operator will proceed through E-0, and then transition to E-2, Faulted Steam Generator Isolation.

While in E-2 a large Steam Generator Tube Rupture will develop on the B Steam Generator, and the operator will transition to E-3, Steam Generator Tube Rupture.

Because the B Steam Generator is both Ruptured and Faulted, the operator will transition to ECA-3.1, SGTR with Loss of Reactor Coolant, Subcooled Recovery Desired.

Also, while in E-2, it is expected that high temperatures will occur on the RCPs due to low service water flow, requiring the crew to stop these pumps. Because of this the NC condition of the RCS will tend to lower loop Tcold tempE~ratures causing an Orange/Red condition on RCS Integrity. If so, the operator may need to transition to FR-P.1, Response to Imminent Pressurized Thermal Shock Condition.

The scenario will terminate at Step 15 of ECA-3.1, after the crew has monitored conditions for continuing with the Subcooled Recovery procedure, or upon transition to FR-P.1.

Critical Tasks:

1. Manually trip the reactor prior to transition to FR-S.1, "Response to Nuclear Generation/A TWS."

Safety Significance: Failure to trip the reactor when required causes a challengH to the Subcriticality Critical Safety Function that otherwise would not exist. This mis-operation by the operator necessitates the crew taking compensating action which complicates the event mitigation strategy and demonstrates an inability by the operator to reco1~nize a failure of the automatic actuation of the RPS.

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

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