==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts. The crew has been directed to maintain current plant conditions.
On cue from the Chief Examiner, A CW pump will trip on overcurrent and discharge valve V6-50A will fail to close automatically. The crew will take immediate actions lAW AOP-01 2, Partial Loss of Condenser Vacuum or Circulating Water Pump Trip. The operator will take manual action to close V6-50A from the RTGB. Condenser Vacuum will be minimally affected by the loss of A CW Pump. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PZR Spray valve PCV-455B will fail open due to a failure of the controller AUTO function and result in an entry into AOP-019, Malfunction of RCS Pressure Control. Immediate actions will be taken to stabilize RCS pressure. Actions in AOP-019 will direct the crew to take manual control of the PZR Spray Valve and close the valve. The Operator will be able to close the valve; however, PC-455B will remain in MANUAL for the remainder of the scenario. Depending on the timeliness of operator actions, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Service Water Booster Pump A will trip on overcurrent. APP 002-A8, B8, C8 and D8 will be received when the pump trips and will direct the crew to start the standby SWBP from the RTGB and restore normal flow to the CV HVH units. ITS 3.7.7, Condition A, one Service Water System (SWS) train inoperable Restore SWS train to operable status within 72 hours, will be entered for the SWBP failure and ITS 3.6.6, Condition D, Two Containment Cooling Trains inoperable Restore one containment cooling train to operable status within 72 hours, will be entered due to the failure to meet SR 3.6.6.3 (Verify cooling water flow rate to each cooling unit is > 750 gpm) for the CV HVH units. Once the Chief Examiner is satisfied with the Tech Spec compliance, he can cue the next event.
On cue from the Chief Examiner, Control Rod H-10 will drop into the core. The crew will take immediate actions lAW AOP-001, Malfunction of Reactor Control System. Additionally AOP 001 will have the crew verify that only one control rod dropped and transition to Section A of AOP-001. The crew will then take action to reduce reactor and turbine power to less than or equal to 70% within 2 hours using rods and boration to maintain Tavg with +/-1.5°F of Tref. SRO will determine that ITS 3.1.4 Condition B must be entered. ITS 3.1.4 Condition B requires that the rod be restored to within alignment limits within 1 hour OR verify SDM is within limits provided in the COLR within 1 hour AND reduce thermal power to less than 70% RTP AND verify SDM is within the limits provided in the COLR once per 12 hours AND perform SR 3.2.1.1 AND SR 3.2.2.1 within 72 hours AND re-evaluate safety analyses and confirm results remain valid for duration of operation under these conditions within 5 days. If above requirements cannot be achieved then ITS 3.1.4 Condition C will require that the plant be placed in Mode 3 in 6 hours. Due to the rapid reduction of Tave, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Appendix D                                                  NUREG-1 021, Rev. 9, Supp. I
 
Appendix D                                  Scenario Outline                            Form ES-D-1 Examiner is satisfied with the crews actions to perform a controlled reduction in power and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a leak will develop on PZR instrument tubing inside containment that will result in LT-460 Reference Leg Failure. PT-456 will also be impacted and will actuate OTz\T Bistables and alarms due to a reduction in pressure to approximately 2080 psig as sensed by PT-456. The crew may take actions lAW AOP-025, RTGB Instrument Failure, to address LT-460 failed high; however, this is not necessary since LT-460 is not the controlling channel. OWP-030, PLT-2 and/or AOP-025 will direct the crew to replace LT-460 with LT-461 as a controlling channel and remove LT-460 from service. The crew should determine that the failures are related to a common sensing line on the Pressurizer and determine that a leak has developed. Due to the failure of LT-460, ITS Table 3.3.1 Table 3.3.1-I Item 8 which requires 3 Pressurizer Water Level High Channel to be operable will not be met and require entry into ITS 3.3.1 Condition M, which requires the channel to placed in trip with 6 hours OR reduce thermal power to less than P-7 within 12 hours. Due to the failure of PT-456, ITS Table 3.3.1-1, Items 5 and 7 which requires 3 OTAT Channels and 3 Pressurizer Pressure Channels to be operable will not be met and require entry into ITS 3.3.1 Conditions E and M. Condition E requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours. Condition M requires that the channel be placed in trip in 6 hours or reduce thermal power to less than P-7 within 13 hours. Also due to the failure of PT-456, ITS Table 3.3.2-1, Items I .d and 6.a which requires 3 Pressurizer Pressure Low Safety Injection Channels and 3 Pressurizer Pressure Low ESFAS Interlock Channels to be operable will not be met and require entry into ITS 3.3.2 Conditions D and H. Condition D requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours and Mode 4 in 18 hours. Condition H requires that the interlock be verified in the required state for existing unit condition within 1 hour OR be in Mode 3 in 7 hours and Mode 4 in 13 hours. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a seismic event will occur. APP-036-15, Seismic Monitor, alarm will be received along with a call from the Load Dispatcher reporting seismic events have been noted in the area from the US Geological Department. The crew will take actions lAW AOP-021, Seismic Disturbances. If dispatched, operator(s) will report that the DBE/SSE ALARM on Seismic Monitor A and the OBE ALARM on Seismic Monitor B are both EXTINGUISHED.
TRM 3.17, Seismic Shutdown, requirements are not met and thus entry in TRM 3.17 is not required. The seismic event will cause a RCS leak to develop and degrade to approximately 250 gpm over a 51/2 minute time period. The crew will enter AOP-016, Excessive Primary Plant Leakage, and take prescribed actions to mitigate the RCS leakage. ITS 3.4.13 RCS Operational Leakage, Condition B, will be entered due to having pressure boundary leakage and require that the plant be placed in Mode 3 in 6 hours and Mode 5 in 36 hours. The crew will ultimately determine that the leak rate is greater than the available charging pump capacity and initiate a reactor trip and safety injection and transition to EOP-E-0, Reactor Trip or Safety Injection.
Appendix D                                                      NUREG-1 021, Rev. 9, Supp. I
 
Appendix D                                  Scenario Outline                          Form ES-D-1 Immediately upon the initiation of the reactor trip the RCS leak will degrade to a Large Break LOCA. During the performance of EOP-E-0 the crew will determine that both A SI Pump and A RHR Pump failed to auto-start. The crew will manually start both A SI Pump and A RHR Pump. Ten seconds after starting A RHR Pump the B RHR Pump will trip. Additionally, the crew will identify that CR HVAC failed to properly align to Emergency Pressurization Mode and must be manually realigned from the RTGB. When Containment Pressure exceeds 10 psig the A CV Spray Pump will fail to Auto-start and the B CV Spray Pump will trip 10 seconds after starting. This will ultimately be identified and A CV Spray Pump will be manually started from the RTGB.
After completing the required actions of EOP-E-0 the crew will transition to FRP-P. 1, Response to Imminent Pressurized Thermal Shock, due to the rapid RCS depressurization and cooldown but exited due to the presence of a Large Break LOCA. The crew will then transition to EOP-E 1, Loss of Reactor or Secondary Coolant, and performs required actions. While performing steps in EOP-E-1 the A RHR Pump will trip on over-current. This will cause the crew to ultimately transition to EPP-15, Loss of Emergency Coolant Recirculation, due to not having at least one train of cold leg recirculation capability. EPP-1 5 will have the crew minimize CV Spray and ECCS flow. After verifying required CV Spray pump operating the crew will be notified that the problem with B RHR Pump has been corrected and can be started as needed.
The Chief Examiner may terminate the scenario at any time after B RHR Pump has been started and crew transitions back to EOP-E-1 from EPP-1 5.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 68% RTP. Engineering has requested that power be held at 68% while monitoring the recently replaced motor on A MFP. Additionally, Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations.
Repairs on HVH-4 are on hold awaiting parts.
On cue from the Chief Examiner, HVH-9A, CV Concrete Shield Cooling Fan, trips and HVH-9B fails to Auto-Start. The operator will verify the standby fan starts by manually starting HVH-9B from the RTGB in accordance with APP-010-A7, HVH-9AIB AIR FLOW LOST/OVLD. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, A Main Feed Pump will trip. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-01 0 the crew will determine that Reactor Power is required to be lowered to less than 60% Reactor Power. The crew will perform the load reduction in accordance with AOP-01 0 and OP-301, RCS Boration Quick Checklist. Once the Chief Examiner is satisfied with the crews actions to perform a controlled reduction in power and stabilize the plant, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the RCP Seal Injection Strainer will become clogged. The crew will determine the strainer is clogged by observing a reduction in RCP seal injection flow to zero flow along with receiving APP-001-A2, Seal Water Injection Filter High AP, APP-001-B4, RCP Seal Injection HI/LO Flow, and APP-001-B3, RCP A Bearing HI Temperature. APP-001-A2 will direct the crew to dispatch an auxiliary operator to check Seal Water Injection Filter AP and will ultimately direct the crew to have the auxiliary operator shift seal injection filters using OP-301. The CRS will enter AOP-01 8, Reactor Coolant Pump Abnormal Conditions, and enter Section C, Loss of Seal Injection. AOP-018 will also diagnose the event as a clogged strainer and direct the crew to shift seal injection filters. Once the seal injection filters are shifted the RCP seal injection flows will return to normal. While seal injection flow is less than 6 gpm to any RCP the CRS will determine that ITS LCO 3.4.17, Condition E, is applicable since seal injection to any RCP is not within limit with at least one charging pump operable. The required action is to initiate action to restore seal injection to affected RCPs immediately and be in Mode 3 in 6 hours and Mode 5 in 36 hours. Once the Chief Examiner is satisfied with the crews actions to restore seal injection flow and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Pressure Transmitter PT-145 for Letdown Line Pressure will fail LOW, causing PCV-145 to close and isolate letdown flow. AOP-025, RTGB Instrument Failure, Section A will be implemented to isolate the letdown line, reduce charging flow and place Excess Letdown in service. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PT-495, Main Steam Line C Pressure Transmitter, will fail low. The BOP will perform immediate actions of AOP-025, RTGB Instrument Failure, Section G, and take manual control of FCV-498, C SIG Feed Regulating Valve, and restore C SIG level to the normal band. The crew will then take action to swap to the alternate channel, place the C FRV back in Automatic and remove PT-495 from service in accordance with OWP-025, SGP-1 1. Due to the failure of PT-495, ITS Table 3.3.1 Table 3.3.1-1 Item 14 which requires 2 Appendix D                                                    NUREG-1 021, Rev. 9, Supp. I
 
Appendix D                                Scenario Outline                            Form ES-D-1  I Steam Flow I Feedwater Flow Mismatch Channels to be operable will not be met and require entry into ITS 3.3.1 Condition E, which requires the channel to placed in trip with 6 hours OR be in Mode 3 in 12 hours. Due to the failure of PT-495, ITS Table 3.3.2-1, Items I.e which requires 3 Steam Line High Differential Pressure between Steam header and Steam Lines Channels to be operable will not be met and require entry into ITS 3.3.2 Condition D. Also due to the failure of PT-495, ITS Table 3.3.3-1, Item 20 which requires 2 Steam Generator Pressure Channels per SIG to be operable will be reviewed and determined to be met. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the plant will experience a fault on the 72 inch Main Steam Header. The crew will determine that a reactor trip is required and transition to EOP-E-0, Reactor Trip or Safety Injection. An automatic safety injection signal will be initiated due to high steam line flow with low Tavg. During the immediate actions of EOP-E-0 it will be determined that the Turbine failed to automatically trip and manual actions will be taken to trip the turbine from the RTGB. During further actions of EOP-E-0 it will be discovered that SI-870A and B, BIT Outlets, fail to automatically open and have to be manually opened from the RTGB in order to provide safety injection flow. All Main Steam Isolation Valves will fail to automatically close and manually actions will be taken to close them from the RTGB. C MSIV will remain failed in the open position. V2-6A, B, and C, Feedwater Header Section Valves, will fail to automatically close and will have to be manually closed from the RTGB. A Motor Driven Auxiliary Feedwater Pump will fail to automatically start and will be manually started from the RTGB.
Once C SIG has dried out a 400 gpm tube rupture will ramp in over 60 seconds on C SIG.
The crew will complete EOP-E-0 and transition to EOP-E-2, Faulted Steam Generator Isolation, and perform the actions to isolate C SIG. Once C SIG is isolated the crew will then transition to EOP-E-3, Steam Generator Tube Rupture, due to elevated readings on R-31 C, Main Steam Line Channel, and continued steam flow from C SIG. Since C MSIV cannot be closed the crew will direct local isolation of C SIG. Ultimately the crew will transition to EPP-1 7, SGTR with Loss of Reactor Coolant: Subcooled Recovery, and secure all but one RCP and one Safety Injection pump.
The Chief Examiner may terminate the scenario at any time after one safety injection pump has been secured in accordance with EPP-17.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts.
On cue from the Chief Examiner, PT-447, Turbine First Stage Pressure Transmitter, fails low.
The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section H, and verify S/Gs trending to 39% and place Rod Control in Manual. SIG levels will be restored to normal, alternate channel selected and feedwater regulating valves returned to automatic. Rod control will be returned to automatic once Tavg verified in the required band. PT-447 will then be removed from service in accordance with OWP-033, FSP-2. Failure of PT-447 will result in ITS Table 3.3.1-1, Item 17e, requirement to have 2 Turbine Impulse Pressure, P-7 inputs available for Reactor Protection System Interlocks to not be met. ITS LCO 3.3.1, Condition T, will be entered which requires that the P-7 interlock be verified in the required state for existing unit conditions within 1 hour OR be in Mode 3 in 7 hours. ITS Table 3.3.2-1, Items if, ig, 4d, and 4e, requirement to have 2 High Steam Flow in Two Steam Lines for Safety Injection and Steam Line Isolation will not be met. ITS LCO 3.3.2, Condition D, will be entered which requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours AND be in Mode 4 in 18 hours. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, TCV-i44, Letdown Temperature Controller, will fail close causing letdown temperature to rise above 135°F. TCV-123, VCT/DEMIN Dlv, will fail to divert letdown flow to the VCT and manual action will be taken to divert letdown flow from the RTGB in accordance with APP-001 -A6, LTDN FLOW HI TEMP DEMIN BYPD. The operator will then determine that TCV-144 has failed closed and take manual actions at the RTGB to open TCV 144 to re-establish cooling flow to the Non-regenerative Heat Exchanger in accordance with APP-00i-A6. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, NI-44, Power Range, Upper Detector will fail high. The channel will be removed from service in accordance with OWP-0i 1, N 1-4. N 1-44 failure will result in ITS Table 3.3.1-i, Items 2, 17.c and 17.d, requirements to have 4 Power Range Neutron Flux Channels to not be met. ITS LCO 3.3.1, Conditions D, S and T will be entered.
Condition D requires that the channel be placed in trip within 6 hours and SR 3.2.4.2 be performed once per 12 hours. Conditions S and T requires that the interlock is verified in the required state for existing unit conditions within 1 hour OR be in Mode 3 in 7 hours (Condition S)
OR be in Mode 2 in 7 hours (Condition T). Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, HCV-1459 will fail open. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-Oi 0 the crew will determine that Reactor Power is required to be controlled less than 100% and take action to lower turbine load. Once Reactor Power is stabilized below 100%, the crew will receive a report from Operations Management that Engineering has noted an unusual noise and vibration on A MFP and recommends that Appendix D                                                  NUREG-1 021, Rev. 9, Supp. I
 
Appendix D                                  Scenario Outline                          Form ES-D-1 Reactor Power be reduced to 70% power in accordance with AOP-038, Rapid Downpower.
Once the Chief Examiner is satisfied with the crews actions to lower reactor power in a controlled manner, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the A S/G level median selector module will fail resulting in a loss of SIG level input to the A Feedwater Regulating Valve. The crew will take immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction, with the BOP taking manual control of A FRy. Once the Chief Examiner is satisfied with the crews actions to control and stabilize A SIG level, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, three main turbine governor valves will begin to randomly oscillate and ultimately fail closed resulting in a Secondary Load Rejection. The crew may decide to take a conservative action and initiate a reactor trip and transition to EOP-E-0, Reactor Trip or Safety Injection. However, the crew may enter AOP-015, Secondary Load Rejection, and attempt to diagnose the problem. Once in AOP-015 the crew will eventually reach a continuous action step that requires the crew to trip the reactor if greater than two governor valves indicate closed. During the fast-bus transfer following the Reactor Trip, 4KV Bus 3 will lose power from the Start-up Transformer due to breaker 52/17 tripping open. On the loss of 4KV Bus 3 the B RCP will experience a locked rotor along with a total seal stack failure and suction line leak. Additionally, B EDG will fail resulting in a loss of power to 480V Bus E-2.
Due to the seal failure and suction line leak on B RCP a safety injection will be required. Only A train ECCS components will be available due to the loss of Bus E-2. However, A SI Pump does not auto-start and must be manually started from the RTGB. Also during the reactor trip the Steam Driven Auxiliary Feedwater Pump will trip and neither A or B Motor Driven Auxiliary Feedwater Pump will automatically start. CVC-200A, Letdown Orifice Isolation, and
( CVC-204A and CVC-240B, Letdown Line Isolation Valves, fail to close as required on the Phase A signal. During the performance of EOP-E-0 the crew should dispatch personnel to investigate and troubleshoot the failure of B EDG. If dispatched, maintenance personnel will determine and correct the cause (fuel racks found tripped and reset) and recommend that the B EDG be started locally. If personnel are not dispatched then 480V Bus E-2 will remain deenergized. With 480V Bus E-2 denergized MCC-6 will not have power and thus LCV-1 I SC, VCT Isolation, will remain in the open position preventing Charging Pump suction swapover to the RWST. If not identified this will eventually result in a loss of suction to the Charging Pumps and lead to gas binding if LCV-1 1 5C is not closed locally. If gas binding of the Charging Pumps occurs then all Charging Pumps will be secured, LCV-1 1 5C will have to be locally closed and Charging Pumps vented prior to restoring charging pump flow.
The crew will progress through EOP-E-0 and address the malfunctions discussed above.
Additionally, subcooling will lower to the point at which RCP Trip Criteria is met and all RCPs will be secured. EOP-E-0 will eventually direct the crew to transition to EOP-E-1, Loss of Reactor or Secondary Coolant. At some point during the performance of EOP-E-0 or EOP-E-1 the crew is expected to realize that B RCP experienced a seal failure and that AOP-01 8, Reactor Coolant Pump Abnormal Conditions, is required to be implemented since it is a Concurrent AOP. The crew will perform EOP-E-1 and eventually transition to EPP-8, Post LOCA Cooldown and Depressurization, and initiate RCS Cooldown to Cold Shutdown and Depressurization of the RCS to refill the PZR.
The Chief Examiner may terminate the scenario at any time after RCS Cooldown and/or RCS Depressurization has commenced in accordance with EPP-8.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 1OE-8 amps performing a plant startup in accordance with GP-003, Normal Plant Startup from Hot Shutdown to Critical. The crew will continue with GP-003 at Step 8.4, Post Critical Operations, and withdraw control rods to the Point of Adding Heat and then stabilize Reactor Power between 3% and 5%. Once the Chief Examiner is satisfied with the crews actions to stabilize reactor power, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PT-445, Pressurizer Pressure Transmitter, fails High. The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section C, and attempt to close PCV-456, PZR PORV. PCV-456 will fail to fully close and the operator will take manual action to close the PORV Block Valve. Once the PORV Block Valve is close PZR Pressure will automatically recover to normal band. Due to the failure of PCV-456 to fully close the SRO will determine that ITS LCO Condition B, is applicable due to one PORV inoperable and not capable of being manually cycled. This LCO requires that the block valve be closed within 1 hour and power removed from the associated block valve within 1 hour and restore PORV to operable status within 72 hours. Once the Chief Examiner is satisfied with the crews actions to control PZR Pressure and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a Service Water Break will occur at the Suction of A SWBP.
The crew will implement AOP-022, Loss of Service Water, Section D, for Leak on South Service Water Header Downstream of Check Valve SW-545. The crew will perform required valve and Service Water Booster Pump manipulations from the RTGB and direct field actions in accordance with AOP-022 attachments to isolate the ruptured section of Service Water piping and restore various components to operable status. The Service Water Break will result in entry into ITS LCO 3.7.5, Condition C, due to Service Water supply to AFW system being inoperable and requires that the plant be in Mode 3 in 6 hours and Mode 4 in 18 hours without reliance on steam generator for heat removal. ITS LCO 3.7.7, Condition A, is also applicable due to one Service Water train inoperable and requires that the train be restored to operable status within 72 hours or be in Mode 3 in 6 hours and Mode 5 in 36 hours. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, B RCP will experience a 40 gpm thermal barrier leak. This will be identified by a rising trend and alarm on R-17, rising CCW surge tank level, and RCP thermal barrier cooling water high flow alarm. FCV-626, Thermal Barrier Flow Control, will receive the signal to auto-close, however the breaker to the MOV will trip leaving the valve in mid-position. The crew will take action to close CC-735, Thermal Barrier Outlet Isolation, from the RTGB due to the FCV-626 failure. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a 300 gpm tube leak on A S!G will be ramped over a six minute time period. The crew will enter AOP-035, SIG Tube Leak, and attempt to control pressurizer level. Ultimately the crew will determine that the leak is greater than the capacity of available charging pumps and initiate a reactor trip and safety injection. The reactor will not trip on an automatic signal or by depressing the right hand reactor trip pushbutton. The RO will identify this failure and trip the reactor by depressing the left hand reactor trip pushbutton. On the initiation of the Reactor Trip the SIG tube leak will degrade to 1000 gpm. On initiation of the Appendix D                                                    NUREG-1021, Rev. 9, Supp. 1
 
Appendix D                                Scenario Outline                            Form ES-D-1  I Safety Injection the Feedwater Regulating Bypass Valves will fail to close on the Phase A signal. The BOP will take manual action to adjust the individual valves potentiometer on the RTGB to close the valves. Additionally, the Motor Driven Feedwater Pumps Discharge Valves will fail to Auto-Open. This failure will be identified, but the crew may determine it not necessary to open the valves until needed due to adequate SIG levels present at the onset of the major event. The crew will carry out the actions of EOP-E-0, Reactor Trip or Safety Injection, identifying the conditions noted above and stabilizing the plant. The crew will transition from EOP-E-0 to EOP-E-3, Steam Generator Tube Rupture. Once A S/G has been isolated and an operator dispatched to deenergize the associated AFW valves the plant will experience a loss of off-site power. On the loss of off-site power, the Main Steam Supply valves to the Steam Driven AFW Pump will fail to open. The crew will take required actions to restart safeguards equipment since SI would have been reset at this point in the EOP Network. After safeguards equipment has been restarted the crew will perform an RCS cooldown and depressurization to stop the primary to secondary leakage. The crew will be required to either open the MDAFW Pump Motor Operated Discharge Valves (V2-16s) or manually start the SDAFW pump to provide AFW flow during the RCS cooldown. Once the primary to secondary leakage is stopped, both safety injection pumps will be secured.
The Chief Examiner may terminate the scenario at any time after the safety injection pumps have been secured in accordance with EOP-E-3, or at his discretion.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts. The crew has been directed to maintain current plant conditions.
On cue from the Chief Examiner, A CW pump will trip on overcurrent and discharge valve V6-50A will fail to close automatically. The crew will take immediate actions lAW AOP-012, Partial Loss of Condenser Vacuum or Circulating Water Pump Trip. The operator will take manual action to close V6-50A from the RTGB. Condenser Vacuum will be minimally affected by the loss of A CW Pump. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PZR Spray valve PCV-455B will fail open due to a failure of the controller AUTO function and result in an entry into AOP-01 9, Malfunction of RCS Pressure Control. Immediate actions will be taken to stabilize RCS pressure. Actions in AOP-019 will direct the crew to take manual control of the PZR Spray Valve and close the valve. The Operator will be able to close the valve; however, PC-455B will remain in MANUAL for the remainder of the scenario. Depending on the timeliness of operator actions, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Service Water Booster Pump A will trip on overcurrent. APP 002-A8, B8, C8 and D8 will be received when the pump trips and will direct the crew to start the standby SWBP from the RTGB and restore normal flow to the CV HVH units. ITS 3.7.7, Condition A, one Service Water System (SWS) train inoperable Restore SWS train to operable status within 72 hours, will be entered for the SWBP failure and ITS 3.6.6, Condition D, Two Containment Cooling Trains inoperable Restore one containment cooling train to operable status within 72 hours, will be entered due to the failure to meet SR 3.6.6.3 (Verify cooling water flow rate to each cooling unit is> 750 gpm) for the CV HVH units. Once the Chief Examiner is satisfied with the Tech Spec compliance, he can cue the next event.
On cue from the Chief Examiner, Control Rod H-i 0 will drop into the core. The crew will take immediate actions lAW AOP-001, Malfunction of Reactor Control System. Additionally AOP 001 will have the crew verify that only one control rod dropped and transition to Section A of AOP-001. The crew will then take action to reduce reactor and turbine power to less than or equal to 70% within 2 hours using rods and boration to maintain Tavg with +/-1.5°F of Tref. SRO will determine that ITS 3.1.4 Condition B must be entered. ITS 3.1.4 Condition B requires that the rod be restored to within alignment limits within 1 hour OR verify SDM is within limits provided in the COLR within 1 hour AND reduce thermal power to less than 70% RTP AND verify SDM is within the limits provided in the COLR once per 12 hours AND perform SR 3.2.1.1 AND SR 3.2.2.1 within 72 hours AND re-evaluate safety analyses and confirm results remain valid for duration of operation under these conditions within 5 days. If above requirements cannot be achieved then ITS 3.1.4 Condition C will require that the plant be placed in Mode 3 in 6 hours. Due to the rapid reduction of Tave, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Appendix D                                                  NUREG-1 021, Rev. 9, Supp. I

On cue from the Chief Examiner, a leak will develop on PZR instrument tubing inside containment that will result in LT-460 Reference Leg Failure. PT-456 will also be impacted and will actuate OTAT Bistables and alarms due to a reduction in pressure to approximately 2080 psig as sensed by PT-456. The crew may take actions lAW AOP-025, RTGB Instrument Failure, to address LT-460 failed high; however, this is not necessary since LT-460 is not the controlling channel. OWP-030, PLT-2 and/or AOP-025 will direct the crew to replace LT-460 with LT-461 as a controlling channel and remove LT-460 from service. The crew should determine that the failures are related to a common sensing line on the Pressurizer and determine that a leak has developed and perform the actions of AOP-01 6, Excessive Primary Plant Leakage and AOP-005, Radiation Monitoring System. Due to the failure of LT-460, ITS Table 3.3.1 Table 3.3.1-1 Item 8 which requires 3 Pressurizer Water Level High Channel to be operable will not be met and require entry into ITS 3.3.1 Condition M, which requires the channel to placed in trip with 6 hours OR reduce thermal power to less than P-7 within 12 hours.
Due to the failure of PT-456, ITS Table 3.3.1-1, Items 5 and 7 which requires 3 OTAT Channels and 3 Pressurizer Pressure Channels to be operable will not be met and require entry into ITS 3.3.1 Conditions E and M. Condition E requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours. Condition M requires that the channel be placed in trip in 6 hours or reduce thermal power to less than P-7 within 13 hours. Also due to the failure of PT-456, ITS Table 3.3.2-1, Items I .d and 6.a which requires 3 Pressurizer Pressure Low Safety Injection Channels and 3 Pressurizer Pressure Low ESFAS Interlock Channels to be operable will not be met and require entry into ITS 3.3.2 Conditions D and H. Condition D requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours and Mode 4 in 18 hours. Condition H requires that the interlock be verified in the required state for existing unit condition within 1 hour OR be in Mode 3 in 7 hours and Mode 4 in 13 hours. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a seismic event will occur. APP-036-15, Seismic Monitor, alarm will be received along with a call from the Load Dispatcher reporting seismic events have been noted in the area from the US Geological Department. The crew will take actions lAW AOP-021, Seismic Disturbances. If dispatched, operator(s) will report that the DBE/SSE ALARM on Seismic Monitor A and the OBE ALARM on Seismic Monitor B are both EXTINGUISHED.
TRM 3.17, Seismic Shutdown, requirements are not met and thus entry in TRM 3.17 is not required. The seismic event will cause a RCS leak to develop and degrade to approximately 250 gpm over a 5 % minute time period. The crew will enter AOP-01 6, Excessive Primary Plant Leakage, and take prescribed actions to mitigate the RCS leakage. ITS 3.4.13 RCS Operational Leakage, Condition B, will be entered due to having pressure boundary leakage and require that the plant be placed in Mode 3 in 6 hours and Mode 5 in 36 hours. The crew will ultimately determine that the leak rate is greater than the available charging pump capacity and initiate a reactor trip and safety injection and transition to EOP-E-0, Reactor Trip or Safety Injection.

Appendix D                                  Scenario Outline                          Form ES-D-1  I Immediately upon the initiation of the reactor trip the RCS leak will degrade to a Large Break LOCA. During the performance of EOP-E-0 the crew will determine that both A SI Pump and A RHR Pump failed to auto-start. The crew will manually start both A SI Pump and A RHR Pump. Ten seconds after starting A RHR Pump the B RHR Pump will trip. Additionally, the crew will identify that CR HVAC failed to properly align to Emergency Pressurization Mode and must be manually realigned from the RTGB. When Containment Pressure exceeds 10 psig the A CV Spray Pump will fail to Auto-start and the B CV Spray Pump will trip 10 seconds after starting. This will ultimately be identified and A CV Spray Pump will be manually started from the RTGB.
After completing the required actions of EOP-E-0 the crew will transition to FRP-P. 1, Response to Imminent Pressurized Thermal Shock, due to the rapid RCS depressurization and cooldown but exited due to the presence of a Large Break LOCA. The crew will then transition to EOP-E 1, Loss of Reactor or Secondary Coolant, and performs required actions. While performing steps in EOP-E-1 the A RHR Pump will trip on over-current. This will cause the crew to ultimately transition to EPP-15, Loss of Emergency Coolant Recirculation, due to not having at least one train of cold leg recirculation capability. EPP-1 5 will have the crew minimize CV Spray and ECCS flow. After verifying required CV Spray pump operating the crew will be notified that the problem with B RHR Pump has been corrected and can be started as needed.
The Chief Examiner may terminate the scenario at any time after B RHR Pump has been started and crew transitions back to EOP-E-1 from EPP-1 5.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 68% RTP. Engineering has requested that power be held at 68% while monitoring the recently replaced motor on A MFP. Additionally, Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations.
Repairs on HVH-4 are on hold awaiting parts.
On cue from the Chief Examiner, HVH-9A, CV Concrete Shield Cooling Fan, trips and HVH-9B fails to Auto-Start. The operator will verify the standby fan starts by manually starting HVH-9B from the RTGB in accordance with APP-010-A7, HVH-9AIB AIR FLOW LOST/OVLD. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, A Main Feed Pump will trip. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-010 the crew will determine that Reactor Power is required to be lowered to less than 60% Reactor Power. The crew will perform the load reduction in accordance with AOP-010 and OP-301, RCS Boration Quick Checklist. Once the Chief Examiner is satisfied with the crews actions to perform a controlled reduction in power and stabilize the plant, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the RCP Seal Injection Strainer will become clogged. The crew will determine the strainer is clogged by observing a reduction in RCP seal injection flow to zero flow along with receiving APP-001-A2, Seal Water Injection Filter High zP, APP-001-B4, RCP Seal Injection HI/LO Flow, and APP-001-B3, RCP A Bearing HI Temperature. APP-001-A2 will direct the crew to dispatch an auxiliary operator to check Seal Water Injection Filter AP and will ultimately direct the crew to have the auxiliary operator shift seal injection filters using OP-301. The CRS will enter AOP-01 8, Reactor Coolant Pump Abnormal Conditions, and enter Section C, Loss of Seal Injection. AOP-018 will also diagnose the event as a clogged strainer and direct the crew to shift seal injection filters. Once the seal injection filters are shifted the RCP seal injection flows will return to normal. While seal injection flow is less than 6 gpm to any RCP the CRS will determine that ITS LCO 3.4.17, Condition E, is applicable since seal injection to any RCP is not within limit with at least one charging pump operable. The required action is to initiate action to restore seal injection to affected RCPs immediately and be in Mode 3 in 6 hours and Mode 5 in 36 hours. Once the Chief Examiner is satisfied with the crews actions to restore seal injection flow and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Pressure Transmitter PT-145 for Letdown Line Pressure will fail LOW, causing PCV-145 to close and isolate letdown flow. AOP-025, RTGB Instrument Failure, Section A will be implemented to isolate the letdown line, reduce charging flow and place Excess Letdown in service. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PT-495, Main Steam Line C Pressure Transmitter, will fail low. The BOP will perform immediate actions of AOP-025, RTGB Instrument Failure, Section G, and take manual control of FCV-498, C S/G Feed Regulating Valve, and restore C SIG level to the normal band. The crew will then take action to swap to the alternate channel, place the C FRV back in Automatic and remove PT-495 from service in accordance with OWP-025, SGP-11. Due to the failure of PT-495, ITS Table 3.3.1 Table 3.3.1-1 Item 14 which requires 2 Appendix D                                                    NUREG-1 021, Rev. 9, Supp. 1

Due to the failure of PT-495, ITS Table 3.3.2-1, Items I.e which requires 3 Steam Line High Differential Pressure between Steam header and Steam Lines Channels to be operable will not be met and require entry into ITS 3.3.2 Condition D. Also due to the failure of PT-495, ITS Table 3.3.3-1, Item 20 which requires 2 Steam Generator Pressure Channels per SIG to be operable will be reviewed and determined to be met. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the plant will experience a fault on the 72 inch Main Steam Header. The crew will determine that a reactor trip is required and transition to EOP-E-0, Reactor Trip or Safety Injection. An automatic safety injection signal will be initiated due to high steam line flow with low Tavg. During the immediate actions of EOP-E-0 it will be determined that the Turbine failed to automatically trip and manual actions will be taken to trip the turbine from the RTGB. During further actions of EOP-E-0 it will be discovered that SI-870A and B, BIT Outlets, fail to automatically open and have to be manually opened from the RTGB in order to provide safety injection flow. All Main Steam Isolation Valves will fail to automatically close and manually actions will be taken to close them from the RTGB. C MSIV will remain failed in the open position. V2-6A, B, and C, Feedwater Header Section Valves, will fail to automatically close and will have to be manually closed from the RTGB. A Motor Driven Auxiliary Feedwater Pump will fail to automatically start and will be manually started from the RTGB.
Once C SIG has dried out a 400 gpm tube rupture will ramp in over 60 seconds on C SIG.
The crew will complete EOP-E-0 and transition to EOP-E-2, Faulted Steam Generator Isolation, and perform the actions to isolate C SIG. The crew may chose to perform Supplement G to isolate C SIG prior to transitioning to EOP-E-2. Supplement G will direct performance of Supplement N. Once C SIG is isolated the crew will then transition to EOP-E-3, Steam Generator Tube Rupture, due to elevated readings on R-31 C, Main Steam Line Channel, and continued steam flow from C SIG. Since C MSIV cannot be closed the crew will direct local isolation of C S/G. Ultimately the crew will transition to EPP-17, SGTR with Loss of Reactor Coolant: Subcooled Recovery, and secure all but one RCP and one Safety Injection pump.
The Chief Examiner may terminate the scenario at any time after one safety injection pump has been secured in accordance with EPP-17.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts.
On cue from the Chief Examiner, PT-447, Turbine First Stage Pressure Transmitter, fails low.
The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section H, and verify S/Gs trending to 39% and place Rod Control in Manual. S/G levels will be restored to normal, alternate channel selected and feedwater regulating valves returned to automatic. Rod control will be returned to automatic once Tavg verified in the required band. PT-447 will then be removed from service in accordance with OWP-033, FSP-2. Failure of PT-447 will result in ITS Table 3.3.1-1, Item 17e, requirement to have 2 Turbine Impulse Pressure, P-7 inputs available for Reactor Protection System Interlocks to not be met. ITS LCO 3.3.1, Condition T, will be entered which requires that the P-7 interlock be verified in the required state for existing unit conditions within 1 hour OR be in Mode 3 in 7 hours. ITS Table 3.3.2-1, Items if, ig, 4d, and 4e, requirement to have 2 High Steam Flow in Two Steam Lines for Safety Injection and Steam Line Isolation will not be met. ITS LCO 3.3.2, Condition D, will be entered which requires that the channel be placed in trip within 6 hours OR be in Mode 3 in 12 hours AND be in Mode 4 in 18 hours. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, TCV-144, Letdown Temperature Controller, will fail close causing letdown temperature to rise above 135&deg;F. TCV-123, VCT/DEMIN DIV, will fail to divert letdown flow to the VCT and manual action will be taken to divert letdown flow from the RTGB in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD. The operator will then determine that TCV-144 has failed closed and take manual actions at the RTGB to open TCV 144 to re-establish cooling flow to the Non-regenerative Heat Exchanger in accordance with APP-001-A6. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Nl-44, Power Range, Upper Detector will fail high. The channel will be removed from service in accordance with OWP-0i 1, N 1-4. N 1-44 failure will result in ITS Table 3.3.1-1, Items 2, 17.c and 17.d, requirements to have 4 Power Range Neutron Flux Channels to not be met. ITS LCO 3.3.1, Conditions D, S and T will be entered.
Condition D requires that the channel be placed in trip within 6 hours and SR 3.2.4.2 be performed once per 12 hours. Conditions S and T requires that the interlock is verified in the required state for existing unit conditions within 1 hour OR be in Mode 3 in 7 hours (Condition 5)
OR be in Mode 2 in 7 hours (Condition T). Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, HCV-1 459 will fail open. The crew will perform the immediate actions of AOP-0i 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-01 0 the crew will determine that Reactor Power is required to be controlled less than 100% and take action to lower turbine load. Once Reactor Power is stabilized below 100%, the crew will receive a report from Operations Management that Engineering has noted an unusual noise and vibration on A MFP and recommends that Appendix D                                                  NUREG-1 021, Rev. 9, Supp. 1
 
Appendix D                                  Scenario Outline                          Form ES-D-1 Reactor Power be reduced in accordance with AOP-038, Rapid Downpower, and secure A MFP. Once the Chief Examiner is satisfied with the crews actions to lower reactor power in a controlled manner, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the A SIG level median selector module will fail resulting in a loss of S/G level input to the A Feedwater Regulating Valve. The crew will take immediate actions of AOP-O1 0, Main Feedwater / Condensate Malfunction, with the BOP taking manual control of A FRy. Once the Chief Examiner is satisfied with the crews actions to control and stabilize A S/G level, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, three main turbine governor valves will begin to randomly oscillate and ultimately fail closed resulting in a Secondary Load Rejection. The crew may decide to take a conservative action and initiate a reactor trip and transition to EOP-E-0, Reactor Trip or Safety Injection. However, the crew may enter AOP-01 5, Secondary Load Rejection, and attempt to diagnose the problem. Once in AOP-015 the crew will eventually reach a continuous action step that requires the crew to trip the reactor if greater than two governor valves indicate closed. During the fast-bus transfer following the Reactor Trip, 4KV Bus 3 will lose power from the Start-up Transformer due to breaker 52/17 tripping open. On the loss of 4KV Bus 3 the B RCP will experience a locked rotor along with a total seal stack failure and suction line leak. Additionally, B EDG will fail resulting in a loss of power to 480V Bus E-2.
Due to the seal failure and suction line leak on B RCP a safety injection will be required. Only A train ECCS components will be available due to the loss of Bus E-2. However, A SI Pump does not auto-start and must be manually started from the RTGB. Also during the reactor trip the Steam Driven Auxiliary Feedwater Pump will trip and neither A or B Motor Driven Auxiliary Feedwater Pump will automatically start. CVC-200A, Letdown Orifice Isolation, and CVC-204A and CVC-240B, Letdown Line Isolation Valves, fail to close as required on the Phase A signal. During the performance of EOP-E-0 the crew should dispatch personnel to investigate and troubleshoot the failure of B EDG. If dispatched, maintenance personnel will determine and correct the cause (fuel racks found tripped and reset) and recommend that the B EDG be started locally. If personnel are not dispatched then 480V Bus E-2 will remain deenergized. With 480V Bus E-2 denergized MCC-6 will not have power and thus LCV-1 1 5C, VCT Isolation, will remain in the open position preventing Charging Pump suction swapover to the RWST. If not identified this will eventually result in a loss of suction to the Charging Pumps and lead to gas binding if LCV-1 1 SC is not closed locally. If gas binding of the Charging Pumps occurs then all Charging Pumps will be secured, LCV-1 I 5C will have to be locally closed and Charging Pumps vented prior to restoring charging pump flow.
The crew will progress through EOP-E-0 and address the malfunctions discussed above.
Additionally, subcooling will lower to the point at which RCP Trip Criteria is met and all RCPs will be secured. EOP-E-0 will eventually direct the crew to transition to EOP-E-1, Loss of Reactor or Secondary Coolant. At some point during the performance of EOP-E-0 or EOP-E-1 the crew is expected to realize that B RCP experienced a seal failure and that AOP-018, Reactor Coolant Pump Abnormal Conditions, is required to be implemented since it is a Concurrent AOP. The crew will perform EOP-E-1 and eventually transition to EPP-8, Post LOCA Cooldown and Depressurization, and initiate RCS Cooldown to Cold Shutdown and Depressurization of the RCS to refill the PZR.
The Chief Examiner may terminate the scenario at any time after RCS Cooldown and/or RCS Depressurization has commenced in accordance with EPP-8.

==SUMMARY==
DESCRIPTION The crew will assume the watch with the plant at I OE-8 amps performing a plant startup in accordance with GP-003, Normal Plant Startup from Hot Shutdown to Critical. The crew will continue with GP-003 at Step 8.4, Post Critical Operations, and withdraw control rods to the Point of Adding Heat and then stabilize Reactor Power between 3% and 5%. Once the Chief Examiner is satisfied with the crews actions to stabilize reactor power, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PT-445, Pressurizer Pressure Transmitter, fails High. The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section C, and attempt to close PCV-456, PZR PORV. PCV-456 will fail to fully close and the operator will take manual action to close the PORV Block Valve. Once the PORV Block Valve is close PZR Pressure will automatically recover to normal band. Due to the failure of PCV-456 to fully close the CRS will determine that ITS LCO 3.4.11, Condition B, is applicable due to one PORV inoperable and not capable of being manually cycled. This LCO requires that the block valve be closed within 1 hour and power removed from the associated block valve within 1 hour and restore PORV to operable status within 72 hours. Once the Chief Examiner is satisfied with the crews actions to control PZR Pressure and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a Service Water Break will occur at the Suction of A SWBP.
The crew will implement AOP-022, Loss of Service Water, Section D, for Leak on South Service Water Header Downstream of Check Valve SW-545. The crew will perform required valve and Service Water Booster Pump manipulations from the RTGB and direct field actions in
(  accordance with AOP-022 attachments to isolate the ruptured section of Service Water piping and restore various components to operable status. The Service Water Break will result in entry into ITS LCO 3.7.5, Condition C, due to Service Water supply to AFW system being inoperable and requires that the plant be in Mode 3 in 6 hours and Mode 4 in 18 hours without reliance on steam generator for heat removal. ITS LCO 3.7.7, Condition A, is also applicable due to one Service Water train inoperable and requires that the train be restored to operable status within 72 hours or be in Mode 3 in 6 hours and Mode 5 in 36 hours. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, B RCP will experience a 40 gpm thermal barrier leak. This will be identified by a rising trend and alarm on R-17, rising CCW surge tank level, and RCP thermal barrier cooling water high flow alarm. FCV-626, Thermal Barrier Flow Control, will receive the signal to auto-close, however the breaker to the MOV will trip leaving the valve in mid-position. The crew will take action to close CC-735, Thermal Barrier Outlet Isolation, from the RTGB due to the FCV-626 failure. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a 300 gpm tube leak on A SIG will be ramped over a six minute time period. The crew will enter AOP-035, SIG Tube Leak, and attempt to control pressurizer level. Ultimately the crew will determine that the leak is greater than the capacity of available charging pumps and initiate a reactor trip and safety injection. The reactor will not trip on an automatic signal or by depressing the right hand reactor trip pushbutton. The RO will identify this failure and trip the reactor by depressing the left hand reactor trip pushbutton. On the initiation of the Reactor Trip the SIG tube leak will degrade to 1000 gpm. On initiation of the Appendix D                                                    NUREG-1 021, Rev. 9, Supp. I
 
Appendix D                                Scenario Outline                            Form ES-D-1  I Safety Injection the Feedwater Regulating Bypass Valves will fail to close on the Phase A signal. The BOP will take manual action to adjust the individual valves potentiometer on the RTGB to close the valves. Additionally, the Motor Driven Feedwater Pumps Discharge Valves will fail to Auto-Open. This failure will be identified, but the crew may determine it not necessary to open the valves until needed due to adequate SIG levels present at the onset of the major event. The crew will carry out the actions of EOP-E-O, Reactor Trip or Safety Injection, identifying the conditions noted above and stabilizing the plant. The crew will transition from EOP-E-O to EOP-E-3, Steam Generator Tube Rupture. Once A S/G has been isolated and an operator dispatched to de-energize the associated AFW valves the plant will experience a loss of off-site power. On the loss of off-site power, the Main Steam Supply valves to the Steam Driven AFW Pump will fail to open. The crew will take required actions to restart safeguards equipment since SI would have been reset at this point in the EOP Network. After safeguards equipment has been restarted the crew will perform an RCS cooldown and depressurization to stop the primary to secondary leakage. The crew will be required to either open the MDAFW Pump Motor Operated Discharge Valves (V2-16s) or manually start the SDAFW pump to provide AFW flow during the RCS cooldown. Once the primary to secondary leakage is stopped, both safety injection pumps will be secured.
The Chief Examiner may terminate the scenario at any time after the safety injection pumps have been secured in accordance with EOP-E-3, or at his discretion.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts. The crew has been directed to maintain current plant conditions.

On cue from the Chief Examiner, A CW pump will trip on overcurrent and discharge valve V6-50A will fail to close automatically. The crew will take immediate actions lAW AOP-01 2, Partial Loss of Condenser Vacuum or Circulating Water Pump Trip. The operator will take manual action to close V6-50A from the RTGB. Condenser Vacuum will be minimally affected by the loss of A CW Pump. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PZR Spray valve PCV-455B will fail open due to a failure of the controller AUTO function and result in an entry into AOP-019, Malfunction of RCS Pressure Control. Immediate actions will be taken to stabilize RCS pressure. Actions in AOP-019 will direct the crew to take manual control of the PZR Spray Valve and close the valve. The Operator will be able to close the valve; however, PC-455B will remain in MANUAL for the remainder of the scenario. Depending on the timeliness of operator actions, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, Service Water Booster Pump A will trip on overcurrent. APP 002-A8, B8, C8 and D8 will be received when the pump trips and will direct the crew to start the standby SWBP from the RTGB and restore normal flow to the CV HVH units. ITS 3.7.7, Condition A, one Service Water System (SWS) train inoperable Restore SWS train to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, will be entered for the SWBP failure and ITS 3.6.6, Condition D, Two Containment Cooling Trains inoperable Restore one containment cooling train to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, will be entered due to the failure to meet SR 3.6.6.3 (Verify cooling water flow rate to each cooling unit is > 750 gpm) for the CV HVH units. Once the Chief Examiner is satisfied with the Tech Spec compliance, he can cue the next event.

On cue from the Chief Examiner, Control Rod H-10 will drop into the core. The crew will take immediate actions lAW AOP-001, Malfunction of Reactor Control System. Additionally AOP 001 will have the crew verify that only one control rod dropped and transition to Section A of AOP-001. The crew will then take action to reduce reactor and turbine power to less than or equal to 70% within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> using rods and boration to maintain Tavg with +/-1.5°F of Tref. SRO will determine that ITS 3.1.4 Condition B must be entered. ITS 3.1.4 Condition B requires that the rod be restored to within alignment limits within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> OR verify SDM is within limits provided in the COLR within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> AND reduce thermal power to less than 70% RTP AND verify SDM is within the limits provided in the COLR once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> AND perform SR 3.2.1.1 AND SR 3.2.2.1 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> AND re-evaluate safety analyses and confirm results remain valid for duration of operation under these conditions within 5 days. If above requirements cannot be achieved then ITS 3.1.4 Condition C will require that the plant be placed in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Due to the rapid reduction of Tave, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 Examiner is satisfied with the crews actions to perform a controlled reduction in power and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a leak will develop on PZR instrument tubing inside containment that will result in LT-460 Reference Leg Failure. PT-456 will also be impacted and will actuate OTz\T Bistables and alarms due to a reduction in pressure to approximately 2080 psig as sensed by PT-456. The crew may take actions lAW AOP-025, RTGB Instrument Failure, to address LT-460 failed high; however, this is not necessary since LT-460 is not the controlling channel. OWP-030, PLT-2 and/or AOP-025 will direct the crew to replace LT-460 with LT-461 as a controlling channel and remove LT-460 from service. The crew should determine that the failures are related to a common sensing line on the Pressurizer and determine that a leak has developed. Due to the failure of LT-460, ITS Table 3.3.1 Table 3.3.1-I Item 8 which requires 3 Pressurizer Water Level High Channel to be operable will not be met and require entry into ITS 3.3.1 Condition M, which requires the channel to placed in trip with 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR reduce thermal power to less than P-7 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Due to the failure of PT-456, ITS Table 3.3.1-1, Items 5 and 7 which requires 3 OTAT Channels and 3 Pressurizer Pressure Channels to be operable will not be met and require entry into ITS 3.3.1 Conditions E and M. Condition E requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Condition M requires that the channel be placed in trip in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or reduce thermal power to less than P-7 within 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />. Also due to the failure of PT-456, ITS Table 3.3.2-1, Items I .d and 6.a which requires 3 Pressurizer Pressure Low Safety Injection Channels and 3 Pressurizer Pressure Low ESFAS Interlock Channels to be operable will not be met and require entry into ITS 3.3.2 Conditions D and H. Condition D requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and Mode 4 in 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. Condition H requires that the interlock be verified in the required state for existing unit condition within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> OR be in Mode 3 in 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> and Mode 4 in 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a seismic event will occur. APP-036-15, Seismic Monitor, alarm will be received along with a call from the Load Dispatcher reporting seismic events have been noted in the area from the US Geological Department. The crew will take actions lAW AOP-021, Seismic Disturbances. If dispatched, operator(s) will report that the DBE/SSE ALARM on Seismic Monitor A and the OBE ALARM on Seismic Monitor B are both EXTINGUISHED.

TRM 3.17, Seismic Shutdown, requirements are not met and thus entry in TRM 3.17 is not required. The seismic event will cause a RCS leak to develop and degrade to approximately 250 gpm over a 51/2 minute time period. The crew will enter AOP-016, Excessive Primary Plant Leakage, and take prescribed actions to mitigate the RCS leakage. ITS 3.4.13 RCS Operational Leakage, Condition B, will be entered due to having pressure boundary leakage and require that the plant be placed in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The crew will ultimately determine that the leak rate is greater than the available charging pump capacity and initiate a reactor trip and safety injection and transition to EOP-E-0, Reactor Trip or Safety Injection.

Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 Immediately upon the initiation of the reactor trip the RCS leak will degrade to a Large Break LOCA. During the performance of EOP-E-0 the crew will determine that both A SI Pump and A RHR Pump failed to auto-start. The crew will manually start both A SI Pump and A RHR Pump. Ten seconds after starting A RHR Pump the B RHR Pump will trip. Additionally, the crew will identify that CR HVAC failed to properly align to Emergency Pressurization Mode and must be manually realigned from the RTGB. When Containment Pressure exceeds 10 psig the A CV Spray Pump will fail to Auto-start and the B CV Spray Pump will trip 10 seconds after starting. This will ultimately be identified and A CV Spray Pump will be manually started from the RTGB.

After completing the required actions of EOP-E-0 the crew will transition to FRP-P. 1, Response to Imminent Pressurized Thermal Shock, due to the rapid RCS depressurization and cooldown but exited due to the presence of a Large Break LOCA. The crew will then transition to EOP-E 1, Loss of Reactor or Secondary Coolant, and performs required actions. While performing steps in EOP-E-1 the A RHR Pump will trip on over-current. This will cause the crew to ultimately transition to EPP-15, Loss of Emergency Coolant Recirculation, due to not having at least one train of cold leg recirculation capability. EPP-1 5 will have the crew minimize CV Spray and ECCS flow. After verifying required CV Spray pump operating the crew will be notified that the problem with B RHR Pump has been corrected and can be started as needed.

The Chief Examiner may terminate the scenario at any time after B RHR Pump has been started and crew transitions back to EOP-E-1 from EPP-1 5.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 68% RTP. Engineering has requested that power be held at 68% while monitoring the recently replaced motor on A MFP. Additionally, Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations.

Repairs on HVH-4 are on hold awaiting parts.

On cue from the Chief Examiner, HVH-9A, CV Concrete Shield Cooling Fan, trips and HVH-9B fails to Auto-Start. The operator will verify the standby fan starts by manually starting HVH-9B from the RTGB in accordance with APP-010-A7, HVH-9AIB AIR FLOW LOST/OVLD. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, A Main Feed Pump will trip. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-01 0 the crew will determine that Reactor Power is required to be lowered to less than 60% Reactor Power. The crew will perform the load reduction in accordance with AOP-01 0 and OP-301, RCS Boration Quick Checklist. Once the Chief Examiner is satisfied with the crews actions to perform a controlled reduction in power and stabilize the plant, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the RCP Seal Injection Strainer will become clogged. The crew will determine the strainer is clogged by observing a reduction in RCP seal injection flow to zero flow along with receiving APP-001-A2, Seal Water Injection Filter High AP, APP-001-B4, RCP Seal Injection HI/LO Flow, and APP-001-B3, RCP A Bearing HI Temperature. APP-001-A2 will direct the crew to dispatch an auxiliary operator to check Seal Water Injection Filter AP and will ultimately direct the crew to have the auxiliary operator shift seal injection filters using OP-301. The CRS will enter AOP-01 8, Reactor Coolant Pump Abnormal Conditions, and enter Section C, Loss of Seal Injection. AOP-018 will also diagnose the event as a clogged strainer and direct the crew to shift seal injection filters. Once the seal injection filters are shifted the RCP seal injection flows will return to normal. While seal injection flow is less than 6 gpm to any RCP the CRS will determine that ITS LCO 3.4.17, Condition E, is applicable since seal injection to any RCP is not within limit with at least one charging pump operable. The required action is to initiate action to restore seal injection to affected RCPs immediately and be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions to restore seal injection flow and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, Pressure Transmitter PT-145 for Letdown Line Pressure will fail LOW, causing PCV-145 to close and isolate letdown flow. AOP-025, RTGB Instrument Failure, Section A will be implemented to isolate the letdown line, reduce charging flow and place Excess Letdown in service. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PT-495, Main Steam Line C Pressure Transmitter, will fail low. The BOP will perform immediate actions of AOP-025, RTGB Instrument Failure, Section G, and take manual control of FCV-498, C SIG Feed Regulating Valve, and restore C SIG level to the normal band. The crew will then take action to swap to the alternate channel, place the C FRV back in Automatic and remove PT-495 from service in accordance with OWP-025, SGP-1 1. Due to the failure of PT-495, ITS Table 3.3.1 Table 3.3.1-1 Item 14 which requires 2 Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 I Steam Flow I Feedwater Flow Mismatch Channels to be operable will not be met and require entry into ITS 3.3.1 Condition E, which requires the channel to placed in trip with 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Due to the failure of PT-495, ITS Table 3.3.2-1, Items I.e which requires 3 Steam Line High Differential Pressure between Steam header and Steam Lines Channels to be operable will not be met and require entry into ITS 3.3.2 Condition D. Also due to the failure of PT-495, ITS Table 3.3.3-1, Item 20 which requires 2 Steam Generator Pressure Channels per SIG to be operable will be reviewed and determined to be met. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the plant will experience a fault on the 72 inch Main Steam Header. The crew will determine that a reactor trip is required and transition to EOP-E-0, Reactor Trip or Safety Injection. An automatic safety injection signal will be initiated due to high steam line flow with low Tavg. During the immediate actions of EOP-E-0 it will be determined that the Turbine failed to automatically trip and manual actions will be taken to trip the turbine from the RTGB. During further actions of EOP-E-0 it will be discovered that SI-870A and B, BIT Outlets, fail to automatically open and have to be manually opened from the RTGB in order to provide safety injection flow. All Main Steam Isolation Valves will fail to automatically close and manually actions will be taken to close them from the RTGB. C MSIV will remain failed in the open position. V2-6A, B, and C, Feedwater Header Section Valves, will fail to automatically close and will have to be manually closed from the RTGB. A Motor Driven Auxiliary Feedwater Pump will fail to automatically start and will be manually started from the RTGB.

Once C SIG has dried out a 400 gpm tube rupture will ramp in over 60 seconds on C SIG.

The crew will complete EOP-E-0 and transition to EOP-E-2, Faulted Steam Generator Isolation, and perform the actions to isolate C SIG. Once C SIG is isolated the crew will then transition to EOP-E-3, Steam Generator Tube Rupture, due to elevated readings on R-31 C, Main Steam Line Channel, and continued steam flow from C SIG. Since C MSIV cannot be closed the crew will direct local isolation of C SIG. Ultimately the crew will transition to EPP-1 7, SGTR with Loss of Reactor Coolant: Subcooled Recovery, and secure all but one RCP and one Safety Injection pump.

The Chief Examiner may terminate the scenario at any time after one safety injection pump has been secured in accordance with EPP-17.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts.

On cue from the Chief Examiner, PT-447, Turbine First Stage Pressure Transmitter, fails low.

The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section H, and verify S/Gs trending to 39% and place Rod Control in Manual. SIG levels will be restored to normal, alternate channel selected and feedwater regulating valves returned to automatic. Rod control will be returned to automatic once Tavg verified in the required band. PT-447 will then be removed from service in accordance with OWP-033, FSP-2.

ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, TCV-i44, Letdown Temperature Controller, will fail close causing letdown temperature to rise above 135°F. TCV-123, VCT/DEMIN Dlv, will fail to divert letdown flow to the VCT and manual action will be taken to divert letdown flow from the RTGB in accordance with APP-001 -A6, LTDN FLOW HI TEMP DEMIN BYPD. The operator will then determine that TCV-144 has failed closed and take manual actions at the RTGB to open TCV 144 to re-establish cooling flow to the Non-regenerative Heat Exchanger in accordance with APP-00i-A6. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, NI-44, Power Range, Upper Detector will fail high. The channel will be removed from service in accordance with OWP-0i 1, N 1-4. N 1-44 failure will result in ITS Table 3.3.1-i, Items 2, 17.c and 17.d, requirements to have 4 Power Range Neutron Flux Channels to not be met. ITS LCO 3.3.1, Conditions D, S and T will be entered.

Condition D requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and SR 3.2.4.2 be performed once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

On cue from the Chief Examiner, HCV-1459 will fail open. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-Oi 0 the crew will determine that Reactor Power is required to be controlled less than 100% and take action to lower turbine load. Once Reactor Power is stabilized below 100%, the crew will receive a report from Operations Management that Engineering has noted an unusual noise and vibration on A MFP and recommends that Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 Reactor Power be reduced to 70% power in accordance with AOP-038, Rapid Downpower.

Once the Chief Examiner is satisfied with the crews actions to lower reactor power in a controlled manner, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the A S/G level median selector module will fail resulting in a loss of SIG level input to the A Feedwater Regulating Valve. The crew will take immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction, with the BOP taking manual control of A FRy. Once the Chief Examiner is satisfied with the crews actions to control and stabilize A SIG level, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, three main turbine governor valves will begin to randomly oscillate and ultimately fail closed resulting in a Secondary Load Rejection. The crew may decide to take a conservative action and initiate a reactor trip and transition to EOP-E-0, Reactor Trip or Safety Injection. However, the crew may enter AOP-015, Secondary Load Rejection, and attempt to diagnose the problem. Once in AOP-015 the crew will eventually reach a continuous action step that requires the crew to trip the reactor if greater than two governor valves indicate closed. During the fast-bus transfer following the Reactor Trip, 4KV Bus 3 will lose power from the Start-up Transformer due to breaker 52/17 tripping open. On the loss of 4KV Bus 3 the B RCP will experience a locked rotor along with a total seal stack failure and suction line leak. Additionally, B EDG will fail resulting in a loss of power to 480V Bus E-2.

Due to the seal failure and suction line leak on B RCP a safety injection will be required. Only A train ECCS components will be available due to the loss of Bus E-2. However, A SI Pump does not auto-start and must be manually started from the RTGB. Also during the reactor trip the Steam Driven Auxiliary Feedwater Pump will trip and neither A or B Motor Driven Auxiliary Feedwater Pump will automatically start. CVC-200A, Letdown Orifice Isolation, and

( CVC-204A and CVC-240B, Letdown Line Isolation Valves, fail to close as required on the Phase A signal. During the performance of EOP-E-0 the crew should dispatch personnel to investigate and troubleshoot the failure of B EDG. If dispatched, maintenance personnel will determine and correct the cause (fuel racks found tripped and reset) and recommend that the B EDG be started locally. If personnel are not dispatched then 480V Bus E-2 will remain deenergized. With 480V Bus E-2 denergized MCC-6 will not have power and thus LCV-1 I SC, VCT Isolation, will remain in the open position preventing Charging Pump suction swapover to the RWST. If not identified this will eventually result in a loss of suction to the Charging Pumps and lead to gas binding if LCV-1 1 5C is not closed locally. If gas binding of the Charging Pumps occurs then all Charging Pumps will be secured, LCV-1 1 5C will have to be locally closed and Charging Pumps vented prior to restoring charging pump flow.

The crew will progress through EOP-E-0 and address the malfunctions discussed above.

Additionally, subcooling will lower to the point at which RCP Trip Criteria is met and all RCPs will be secured. EOP-E-0 will eventually direct the crew to transition to EOP-E-1, Loss of Reactor or Secondary Coolant. At some point during the performance of EOP-E-0 or EOP-E-1 the crew is expected to realize that B RCP experienced a seal failure and that AOP-01 8, Reactor Coolant Pump Abnormal Conditions, is required to be implemented since it is a Concurrent AOP. The crew will perform EOP-E-1 and eventually transition to EPP-8, Post LOCA Cooldown and Depressurization, and initiate RCS Cooldown to Cold Shutdown and Depressurization of the RCS to refill the PZR.

The Chief Examiner may terminate the scenario at any time after RCS Cooldown and/or RCS Depressurization has commenced in accordance with EPP-8.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 1OE-8 amps performing a plant startup in accordance with GP-003, Normal Plant Startup from Hot Shutdown to Critical. The crew will continue with GP-003 at Step 8.4, Post Critical Operations, and withdraw control rods to the Point of Adding Heat and then stabilize Reactor Power between 3% and 5%. Once the Chief Examiner is satisfied with the crews actions to stabilize reactor power, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PT-445, Pressurizer Pressure Transmitter, fails High. The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section C, and attempt to close PCV-456, PZR PORV. PCV-456 will fail to fully close and the operator will take manual action to close the PORV Block Valve. Once the PORV Block Valve is close PZR Pressure will automatically recover to normal band. Due to the failure of PCV-456 to fully close the SRO will determine that ITS LCO Condition B, is applicable due to one PORV inoperable and not capable of being manually cycled. This LCO requires that the block valve be closed within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and power removed from the associated block valve within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and restore PORV to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions to control PZR Pressure and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a Service Water Break will occur at the Suction of A SWBP.

The crew will implement AOP-022, Loss of Service Water, Section D, for Leak on South Service Water Header Downstream of Check Valve SW-545. The crew will perform required valve and Service Water Booster Pump manipulations from the RTGB and direct field actions in accordance with AOP-022 attachments to isolate the ruptured section of Service Water piping and restore various components to operable status. The Service Water Break will result in entry into ITS LCO 3.7.5, Condition C, due to Service Water supply to AFW system being inoperable and requires that the plant be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 4 in 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> without reliance on steam generator for heat removal. ITS LCO 3.7.7, Condition A, is also applicable due to one Service Water train inoperable and requires that the train be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, B RCP will experience a 40 gpm thermal barrier leak. This will be identified by a rising trend and alarm on R-17, rising CCW surge tank level, and RCP thermal barrier cooling water high flow alarm. FCV-626, Thermal Barrier Flow Control, will receive the signal to auto-close, however the breaker to the MOV will trip leaving the valve in mid-position. The crew will take action to close CC-735, Thermal Barrier Outlet Isolation, from the RTGB due to the FCV-626 failure. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a 300 gpm tube leak on A S!G will be ramped over a six minute time period. The crew will enter AOP-035, SIG Tube Leak, and attempt to control pressurizer level. Ultimately the crew will determine that the leak is greater than the capacity of available charging pumps and initiate a reactor trip and safety injection. The reactor will not trip on an automatic signal or by depressing the right hand reactor trip pushbutton. The RO will identify this failure and trip the reactor by depressing the left hand reactor trip pushbutton. On the initiation of the Reactor Trip the SIG tube leak will degrade to 1000 gpm. On initiation of the Appendix D NUREG-1021, Rev. 9, Supp. 1

Appendix D Scenario Outline Form ES-D-1 I Safety Injection the Feedwater Regulating Bypass Valves will fail to close on the Phase A signal. The BOP will take manual action to adjust the individual valves potentiometer on the RTGB to close the valves. Additionally, the Motor Driven Feedwater Pumps Discharge Valves will fail to Auto-Open. This failure will be identified, but the crew may determine it not necessary to open the valves until needed due to adequate SIG levels present at the onset of the major event. The crew will carry out the actions of EOP-E-0, Reactor Trip or Safety Injection, identifying the conditions noted above and stabilizing the plant. The crew will transition from EOP-E-0 to EOP-E-3, Steam Generator Tube Rupture. Once A S/G has been isolated and an operator dispatched to deenergize the associated AFW valves the plant will experience a loss of off-site power. On the loss of off-site power, the Main Steam Supply valves to the Steam Driven AFW Pump will fail to open. The crew will take required actions to restart safeguards equipment since SI would have been reset at this point in the EOP Network. After safeguards equipment has been restarted the crew will perform an RCS cooldown and depressurization to stop the primary to secondary leakage. The crew will be required to either open the MDAFW Pump Motor Operated Discharge Valves (V2-16s) or manually start the SDAFW pump to provide AFW flow during the RCS cooldown. Once the primary to secondary leakage is stopped, both safety injection pumps will be secured.

The Chief Examiner may terminate the scenario at any time after the safety injection pumps have been secured in accordance with EOP-E-3, or at his discretion.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts. The crew has been directed to maintain current plant conditions.

On cue from the Chief Examiner, A CW pump will trip on overcurrent and discharge valve V6-50A will fail to close automatically. The crew will take immediate actions lAW AOP-012, Partial Loss of Condenser Vacuum or Circulating Water Pump Trip. The operator will take manual action to close V6-50A from the RTGB. Condenser Vacuum will be minimally affected by the loss of A CW Pump. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PZR Spray valve PCV-455B will fail open due to a failure of the controller AUTO function and result in an entry into AOP-01 9, Malfunction of RCS Pressure Control. Immediate actions will be taken to stabilize RCS pressure. Actions in AOP-019 will direct the crew to take manual control of the PZR Spray Valve and close the valve. The Operator will be able to close the valve; however, PC-455B will remain in MANUAL for the remainder of the scenario. Depending on the timeliness of operator actions, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, Service Water Booster Pump A will trip on overcurrent. APP 002-A8, B8, C8 and D8 will be received when the pump trips and will direct the crew to start the standby SWBP from the RTGB and restore normal flow to the CV HVH units. ITS 3.7.7, Condition A, one Service Water System (SWS) train inoperable Restore SWS train to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, will be entered for the SWBP failure and ITS 3.6.6, Condition D, Two Containment Cooling Trains inoperable Restore one containment cooling train to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, will be entered due to the failure to meet SR 3.6.6.3 (Verify cooling water flow rate to each cooling unit is> 750 gpm) for the CV HVH units. Once the Chief Examiner is satisfied with the Tech Spec compliance, he can cue the next event.

On cue from the Chief Examiner, Control Rod H-i 0 will drop into the core. The crew will take immediate actions lAW AOP-001, Malfunction of Reactor Control System. Additionally AOP 001 will have the crew verify that only one control rod dropped and transition to Section A of AOP-001. The crew will then take action to reduce reactor and turbine power to less than or equal to 70% within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> using rods and boration to maintain Tavg with +/-1.5°F of Tref. SRO will determine that ITS 3.1.4 Condition B must be entered. ITS 3.1.4 Condition B requires that the rod be restored to within alignment limits within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> OR verify SDM is within limits provided in the COLR within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> AND reduce thermal power to less than 70% RTP AND verify SDM is within the limits provided in the COLR once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> AND perform SR 3.2.1.1 AND SR 3.2.2.1 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> AND re-evaluate safety analyses and confirm results remain valid for duration of operation under these conditions within 5 days. If above requirements cannot be achieved then ITS 3.1.4 Condition C will require that the plant be placed in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Due to the rapid reduction of Tave, ITS 3.4.1, Condition A, One or more RCS DNB parameters not within limits Restore RCS DNB parameters to within limit within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, will be entered due to PZR Pressure being reduced to less than 2205 psig. Once the Chief Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 I Examiner is satisfied with the crews actions to perform a controlled reduction in power and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a leak will develop on PZR instrument tubing inside containment that will result in LT-460 Reference Leg Failure. PT-456 will also be impacted and will actuate OTAT Bistables and alarms due to a reduction in pressure to approximately 2080 psig as sensed by PT-456. The crew may take actions lAW AOP-025, RTGB Instrument Failure, to address LT-460 failed high; however, this is not necessary since LT-460 is not the controlling channel. OWP-030, PLT-2 and/or AOP-025 will direct the crew to replace LT-460 with LT-461 as a controlling channel and remove LT-460 from service. The crew should determine that the failures are related to a common sensing line on the Pressurizer and determine that a leak has developed and perform the actions of AOP-01 6, Excessive Primary Plant Leakage and AOP-005, Radiation Monitoring System. Due to the failure of LT-460, ITS Table 3.3.1 Table 3.3.1-1 Item 8 which requires 3 Pressurizer Water Level High Channel to be operable will not be met and require entry into ITS 3.3.1 Condition M, which requires the channel to placed in trip with 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR reduce thermal power to less than P-7 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Due to the failure of PT-456, ITS Table 3.3.1-1, Items 5 and 7 which requires 3 OTAT Channels and 3 Pressurizer Pressure Channels to be operable will not be met and require entry into ITS 3.3.1 Conditions E and M. Condition E requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Condition M requires that the channel be placed in trip in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or reduce thermal power to less than P-7 within 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />. Also due to the failure of PT-456, ITS Table 3.3.2-1, Items I .d and 6.a which requires 3 Pressurizer Pressure Low Safety Injection Channels and 3 Pressurizer Pressure Low ESFAS Interlock Channels to be operable will not be met and require entry into ITS 3.3.2 Conditions D and H. Condition D requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and Mode 4 in 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. Condition H requires that the interlock be verified in the required state for existing unit condition within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> OR be in Mode 3 in 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> and Mode 4 in 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a seismic event will occur. APP-036-15, Seismic Monitor, alarm will be received along with a call from the Load Dispatcher reporting seismic events have been noted in the area from the US Geological Department. The crew will take actions lAW AOP-021, Seismic Disturbances. If dispatched, operator(s) will report that the DBE/SSE ALARM on Seismic Monitor A and the OBE ALARM on Seismic Monitor B are both EXTINGUISHED.

TRM 3.17, Seismic Shutdown, requirements are not met and thus entry in TRM 3.17 is not required. The seismic event will cause a RCS leak to develop and degrade to approximately 250 gpm over a 5 % minute time period. The crew will enter AOP-01 6, Excessive Primary Plant Leakage, and take prescribed actions to mitigate the RCS leakage. ITS 3.4.13 RCS Operational Leakage, Condition B, will be entered due to having pressure boundary leakage and require that the plant be placed in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The crew will ultimately determine that the leak rate is greater than the available charging pump capacity and initiate a reactor trip and safety injection and transition to EOP-E-0, Reactor Trip or Safety Injection.

Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 I Immediately upon the initiation of the reactor trip the RCS leak will degrade to a Large Break LOCA. During the performance of EOP-E-0 the crew will determine that both A SI Pump and A RHR Pump failed to auto-start. The crew will manually start both A SI Pump and A RHR Pump. Ten seconds after starting A RHR Pump the B RHR Pump will trip. Additionally, the crew will identify that CR HVAC failed to properly align to Emergency Pressurization Mode and must be manually realigned from the RTGB. When Containment Pressure exceeds 10 psig the A CV Spray Pump will fail to Auto-start and the B CV Spray Pump will trip 10 seconds after starting. This will ultimately be identified and A CV Spray Pump will be manually started from the RTGB.

After completing the required actions of EOP-E-0 the crew will transition to FRP-P. 1, Response to Imminent Pressurized Thermal Shock, due to the rapid RCS depressurization and cooldown but exited due to the presence of a Large Break LOCA. The crew will then transition to EOP-E 1, Loss of Reactor or Secondary Coolant, and performs required actions. While performing steps in EOP-E-1 the A RHR Pump will trip on over-current. This will cause the crew to ultimately transition to EPP-15, Loss of Emergency Coolant Recirculation, due to not having at least one train of cold leg recirculation capability. EPP-1 5 will have the crew minimize CV Spray and ECCS flow. After verifying required CV Spray pump operating the crew will be notified that the problem with B RHR Pump has been corrected and can be started as needed.

The Chief Examiner may terminate the scenario at any time after B RHR Pump has been started and crew transitions back to EOP-E-1 from EPP-1 5.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 68% RTP. Engineering has requested that power be held at 68% while monitoring the recently replaced motor on A MFP. Additionally, Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations.

Repairs on HVH-4 are on hold awaiting parts.

On cue from the Chief Examiner, HVH-9A, CV Concrete Shield Cooling Fan, trips and HVH-9B fails to Auto-Start. The operator will verify the standby fan starts by manually starting HVH-9B from the RTGB in accordance with APP-010-A7, HVH-9AIB AIR FLOW LOST/OVLD. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, A Main Feed Pump will trip. The crew will perform the immediate actions of AOP-01 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-010 the crew will determine that Reactor Power is required to be lowered to less than 60% Reactor Power. The crew will perform the load reduction in accordance with AOP-010 and OP-301, RCS Boration Quick Checklist. Once the Chief Examiner is satisfied with the crews actions to perform a controlled reduction in power and stabilize the plant, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the RCP Seal Injection Strainer will become clogged. The crew will determine the strainer is clogged by observing a reduction in RCP seal injection flow to zero flow along with receiving APP-001-A2, Seal Water Injection Filter High zP, APP-001-B4, RCP Seal Injection HI/LO Flow, and APP-001-B3, RCP A Bearing HI Temperature. APP-001-A2 will direct the crew to dispatch an auxiliary operator to check Seal Water Injection Filter AP and will ultimately direct the crew to have the auxiliary operator shift seal injection filters using OP-301. The CRS will enter AOP-01 8, Reactor Coolant Pump Abnormal Conditions, and enter Section C, Loss of Seal Injection. AOP-018 will also diagnose the event as a clogged strainer and direct the crew to shift seal injection filters. Once the seal injection filters are shifted the RCP seal injection flows will return to normal. While seal injection flow is less than 6 gpm to any RCP the CRS will determine that ITS LCO 3.4.17, Condition E, is applicable since seal injection to any RCP is not within limit with at least one charging pump operable. The required action is to initiate action to restore seal injection to affected RCPs immediately and be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions to restore seal injection flow and demonstrate Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, Pressure Transmitter PT-145 for Letdown Line Pressure will fail LOW, causing PCV-145 to close and isolate letdown flow. AOP-025, RTGB Instrument Failure, Section A will be implemented to isolate the letdown line, reduce charging flow and place Excess Letdown in service. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PT-495, Main Steam Line C Pressure Transmitter, will fail low. The BOP will perform immediate actions of AOP-025, RTGB Instrument Failure, Section G, and take manual control of FCV-498, C S/G Feed Regulating Valve, and restore C SIG level to the normal band. The crew will then take action to swap to the alternate channel, place the C FRV back in Automatic and remove PT-495 from service in accordance with OWP-025, SGP-11. Due to the failure of PT-495, ITS Table 3.3.1 Table 3.3.1-1 Item 14 which requires 2 Appendix D NUREG-1 021, Rev. 9, Supp. 1

Appendix D Scenario Outline Form ES-D-1 Steam Flow I Feedwater Flow Mismatch Channels to be operable will not be met and require entry into ITS 3.3.1 Condition E, which requires the channel to placed in trip with 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Due to the failure of PT-495, ITS Table 3.3.2-1, Items I.e which requires 3 Steam Line High Differential Pressure between Steam header and Steam Lines Channels to be operable will not be met and require entry into ITS 3.3.2 Condition D. Also due to the failure of PT-495, ITS Table 3.3.3-1, Item 20 which requires 2 Steam Generator Pressure Channels per SIG to be operable will be reviewed and determined to be met. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the plant will experience a fault on the 72 inch Main Steam Header. The crew will determine that a reactor trip is required and transition to EOP-E-0, Reactor Trip or Safety Injection. An automatic safety injection signal will be initiated due to high steam line flow with low Tavg. During the immediate actions of EOP-E-0 it will be determined that the Turbine failed to automatically trip and manual actions will be taken to trip the turbine from the RTGB. During further actions of EOP-E-0 it will be discovered that SI-870A and B, BIT Outlets, fail to automatically open and have to be manually opened from the RTGB in order to provide safety injection flow. All Main Steam Isolation Valves will fail to automatically close and manually actions will be taken to close them from the RTGB. C MSIV will remain failed in the open position. V2-6A, B, and C, Feedwater Header Section Valves, will fail to automatically close and will have to be manually closed from the RTGB. A Motor Driven Auxiliary Feedwater Pump will fail to automatically start and will be manually started from the RTGB.

Once C SIG has dried out a 400 gpm tube rupture will ramp in over 60 seconds on C SIG.

The crew will complete EOP-E-0 and transition to EOP-E-2, Faulted Steam Generator Isolation, and perform the actions to isolate C SIG. The crew may chose to perform Supplement G to isolate C SIG prior to transitioning to EOP-E-2. Supplement G will direct performance of Supplement N. Once C SIG is isolated the crew will then transition to EOP-E-3, Steam Generator Tube Rupture, due to elevated readings on R-31 C, Main Steam Line Channel, and continued steam flow from C SIG. Since C MSIV cannot be closed the crew will direct local isolation of C S/G. Ultimately the crew will transition to EPP-17, SGTR with Loss of Reactor Coolant: Subcooled Recovery, and secure all but one RCP and one Safety Injection pump.

The Chief Examiner may terminate the scenario at any time after one safety injection pump has been secured in accordance with EPP-17.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at 100% RTP. Maintenance is currently in progress on Component Cooling Water Pump C for pump mechanical seal replacement. HVH-4 is Out of Service due to Excessive Motor Vibrations. Repairs on HVH-4 are on hold awaiting parts.

On cue from the Chief Examiner, PT-447, Turbine First Stage Pressure Transmitter, fails low.

The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section H, and verify S/Gs trending to 39% and place Rod Control in Manual. S/G levels will be restored to normal, alternate channel selected and feedwater regulating valves returned to automatic. Rod control will be returned to automatic once Tavg verified in the required band. PT-447 will then be removed from service in accordance with OWP-033, FSP-2. Failure of PT-447 will result in ITS Table 3.3.1-1, Item 17e, requirement to have 2 Turbine Impulse Pressure, P-7 inputs available for Reactor Protection System Interlocks to not be met. ITS LCO 3.3.1, Condition T, will be entered which requires that the P-7 interlock be verified in the required state for existing unit conditions within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> OR be in Mode 3 in 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. ITS Table 3.3.2-1, Items if, ig, 4d, and 4e, requirement to have 2 High Steam Flow in Two Steam Lines for Safety Injection and Steam Line Isolation will not be met. ITS LCO 3.3.2, Condition D, will be entered which requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> OR be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> AND be in Mode 4 in 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. ITS Table 3.3.6.1 Item 4 will also be reviewed and determined to be applicable due to affecting Safety Injection ESFAS Instrumentation associated with Containment Ventilation Isolation Instrumentation. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, TCV-144, Letdown Temperature Controller, will fail close causing letdown temperature to rise above 135°F. TCV-123, VCT/DEMIN DIV, will fail to divert letdown flow to the VCT and manual action will be taken to divert letdown flow from the RTGB in accordance with APP-001-A6, LTDN FLOW HI TEMP DEMIN BYPD. The operator will then determine that TCV-144 has failed closed and take manual actions at the RTGB to open TCV 144 to re-establish cooling flow to the Non-regenerative Heat Exchanger in accordance with APP-001-A6. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, Nl-44, Power Range, Upper Detector will fail high. The channel will be removed from service in accordance with OWP-0i 1, N 1-4. N 1-44 failure will result in ITS Table 3.3.1-1, Items 2, 17.c and 17.d, requirements to have 4 Power Range Neutron Flux Channels to not be met. ITS LCO 3.3.1, Conditions D, S and T will be entered.

Condition D requires that the channel be placed in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and SR 3.2.4.2 be performed once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

On cue from the Chief Examiner, HCV-1 459 will fail open. The crew will perform the immediate actions of AOP-0i 0, Main Feedwater I Condensate Malfunction. While performing the remaining actions of AOP-01 0 the crew will determine that Reactor Power is required to be controlled less than 100% and take action to lower turbine load. Once Reactor Power is stabilized below 100%, the crew will receive a report from Operations Management that Engineering has noted an unusual noise and vibration on A MFP and recommends that Appendix D NUREG-1 021, Rev. 9, Supp. 1

Appendix D Scenario Outline Form ES-D-1 Reactor Power be reduced in accordance with AOP-038, Rapid Downpower, and secure A MFP. Once the Chief Examiner is satisfied with the crews actions to lower reactor power in a controlled manner, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, the A SIG level median selector module will fail resulting in a loss of S/G level input to the A Feedwater Regulating Valve. The crew will take immediate actions of AOP-O1 0, Main Feedwater / Condensate Malfunction, with the BOP taking manual control of A FRy. Once the Chief Examiner is satisfied with the crews actions to control and stabilize A S/G level, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, three main turbine governor valves will begin to randomly oscillate and ultimately fail closed resulting in a Secondary Load Rejection. The crew may decide to take a conservative action and initiate a reactor trip and transition to EOP-E-0, Reactor Trip or Safety Injection. However, the crew may enter AOP-01 5, Secondary Load Rejection, and attempt to diagnose the problem. Once in AOP-015 the crew will eventually reach a continuous action step that requires the crew to trip the reactor if greater than two governor valves indicate closed. During the fast-bus transfer following the Reactor Trip, 4KV Bus 3 will lose power from the Start-up Transformer due to breaker 52/17 tripping open. On the loss of 4KV Bus 3 the B RCP will experience a locked rotor along with a total seal stack failure and suction line leak. Additionally, B EDG will fail resulting in a loss of power to 480V Bus E-2.

Due to the seal failure and suction line leak on B RCP a safety injection will be required. Only A train ECCS components will be available due to the loss of Bus E-2. However, A SI Pump does not auto-start and must be manually started from the RTGB. Also during the reactor trip the Steam Driven Auxiliary Feedwater Pump will trip and neither A or B Motor Driven Auxiliary Feedwater Pump will automatically start. CVC-200A, Letdown Orifice Isolation, and CVC-204A and CVC-240B, Letdown Line Isolation Valves, fail to close as required on the Phase A signal. During the performance of EOP-E-0 the crew should dispatch personnel to investigate and troubleshoot the failure of B EDG. If dispatched, maintenance personnel will determine and correct the cause (fuel racks found tripped and reset) and recommend that the B EDG be started locally. If personnel are not dispatched then 480V Bus E-2 will remain deenergized. With 480V Bus E-2 denergized MCC-6 will not have power and thus LCV-1 1 5C, VCT Isolation, will remain in the open position preventing Charging Pump suction swapover to the RWST. If not identified this will eventually result in a loss of suction to the Charging Pumps and lead to gas binding if LCV-1 1 SC is not closed locally. If gas binding of the Charging Pumps occurs then all Charging Pumps will be secured, LCV-1 I 5C will have to be locally closed and Charging Pumps vented prior to restoring charging pump flow.

The crew will progress through EOP-E-0 and address the malfunctions discussed above.

Additionally, subcooling will lower to the point at which RCP Trip Criteria is met and all RCPs will be secured. EOP-E-0 will eventually direct the crew to transition to EOP-E-1, Loss of Reactor or Secondary Coolant. At some point during the performance of EOP-E-0 or EOP-E-1 the crew is expected to realize that B RCP experienced a seal failure and that AOP-018, Reactor Coolant Pump Abnormal Conditions, is required to be implemented since it is a Concurrent AOP. The crew will perform EOP-E-1 and eventually transition to EPP-8, Post LOCA Cooldown and Depressurization, and initiate RCS Cooldown to Cold Shutdown and Depressurization of the RCS to refill the PZR.

The Chief Examiner may terminate the scenario at any time after RCS Cooldown and/or RCS Depressurization has commenced in accordance with EPP-8.

SUMMARY

DESCRIPTION The crew will assume the watch with the plant at I OE-8 amps performing a plant startup in accordance with GP-003, Normal Plant Startup from Hot Shutdown to Critical. The crew will continue with GP-003 at Step 8.4, Post Critical Operations, and withdraw control rods to the Point of Adding Heat and then stabilize Reactor Power between 3% and 5%. Once the Chief Examiner is satisfied with the crews actions to stabilize reactor power, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, PT-445, Pressurizer Pressure Transmitter, fails High. The crew will perform the immediate actions of AOP-025, RTGB Instrument Failure, Section C, and attempt to close PCV-456, PZR PORV. PCV-456 will fail to fully close and the operator will take manual action to close the PORV Block Valve. Once the PORV Block Valve is close PZR Pressure will automatically recover to normal band. Due to the failure of PCV-456 to fully close the CRS will determine that ITS LCO 3.4.11, Condition B, is applicable due to one PORV inoperable and not capable of being manually cycled. This LCO requires that the block valve be closed within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and power removed from the associated block valve within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and restore PORV to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions to control PZR Pressure and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a Service Water Break will occur at the Suction of A SWBP.

The crew will implement AOP-022, Loss of Service Water, Section D, for Leak on South Service Water Header Downstream of Check Valve SW-545. The crew will perform required valve and Service Water Booster Pump manipulations from the RTGB and direct field actions in

( accordance with AOP-022 attachments to isolate the ruptured section of Service Water piping and restore various components to operable status. The Service Water Break will result in entry into ITS LCO 3.7.5, Condition C, due to Service Water supply to AFW system being inoperable and requires that the plant be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 4 in 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> without reliance on steam generator for heat removal. ITS LCO 3.7.7, Condition A, is also applicable due to one Service Water train inoperable and requires that the train be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Once the Chief Examiner is satisfied with the crews actions and Tech Spec compliance, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, B RCP will experience a 40 gpm thermal barrier leak. This will be identified by a rising trend and alarm on R-17, rising CCW surge tank level, and RCP thermal barrier cooling water high flow alarm. FCV-626, Thermal Barrier Flow Control, will receive the signal to auto-close, however the breaker to the MOV will trip leaving the valve in mid-position. The crew will take action to close CC-735, Thermal Barrier Outlet Isolation, from the RTGB due to the FCV-626 failure. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

On cue from the Chief Examiner, a 300 gpm tube leak on A SIG will be ramped over a six minute time period. The crew will enter AOP-035, SIG Tube Leak, and attempt to control pressurizer level. Ultimately the crew will determine that the leak is greater than the capacity of available charging pumps and initiate a reactor trip and safety injection. The reactor will not trip on an automatic signal or by depressing the right hand reactor trip pushbutton. The RO will identify this failure and trip the reactor by depressing the left hand reactor trip pushbutton. On the initiation of the Reactor Trip the SIG tube leak will degrade to 1000 gpm. On initiation of the Appendix D NUREG-1 021, Rev. 9, Supp. I

Appendix D Scenario Outline Form ES-D-1 I Safety Injection the Feedwater Regulating Bypass Valves will fail to close on the Phase A signal. The BOP will take manual action to adjust the individual valves potentiometer on the RTGB to close the valves. Additionally, the Motor Driven Feedwater Pumps Discharge Valves will fail to Auto-Open. This failure will be identified, but the crew may determine it not necessary to open the valves until needed due to adequate SIG levels present at the onset of the major event. The crew will carry out the actions of EOP-E-O, Reactor Trip or Safety Injection, identifying the conditions noted above and stabilizing the plant. The crew will transition from EOP-E-O to EOP-E-3, Steam Generator Tube Rupture. Once A S/G has been isolated and an operator dispatched to de-energize the associated AFW valves the plant will experience a loss of off-site power. On the loss of off-site power, the Main Steam Supply valves to the Steam Driven AFW Pump will fail to open. The crew will take required actions to restart safeguards equipment since SI would have been reset at this point in the EOP Network. After safeguards equipment has been restarted the crew will perform an RCS cooldown and depressurization to stop the primary to secondary leakage. The crew will be required to either open the MDAFW Pump Motor Operated Discharge Valves (V2-16s) or manually start the SDAFW pump to provide AFW flow during the RCS cooldown. Once the primary to secondary leakage is stopped, both safety injection pumps will be secured.

The Chief Examiner may terminate the scenario at any time after the safety injection pumps have been secured in accordance with EOP-E-3, or at his discretion.

Depressurize RCS to Minimize Break Flow and Refill the PZR:

RO

a. Normal PZR spray AVAILABLE (NO. ao to SteD 18)

CAUTION

. The PRT may rupture if a PZR PORV is used to depressurize SRO the RCS. This may result in abnormal containment conditions.

. Cycling of the PZR PORV should be minimized.

NOTE SRO The upper head region may void during RCS depressurization if RCPs are NOT running. This will result in a rapidly rising PZR level.
