SUMMARY
DESCRIPTION The crew will assume the watch with the plant in mode 2 with reactor startup In progress.
Shutdown banks A&B are fully withdrawn. The crew will continue taking the reactor critical IAW GP-003, NORMAL PLANT STARTUP FROM HOT SHUTDOWN TO CRITICAL. The crew will withdraw control rods to obtain their first doubling. The crew will perform a 1/M plot and proceed to withdraw rods to obtain their second doubling.
On cue from the Chief Examiner, Control Bank B rod K2 will not move. The crew will take actions IAW AOP-001, Malfunction of the Reactor Control System. The operator will perform immediate operator actions. The OAC will diagnose a stuck rod and the crew will transition to Section B, Immovable/Misaligned Rods. The crew will initiate boration of the RCS using OP-301 and borate to All Rods Out 1% Shutdown Boron Concentration to place the plant in mode 3 in preparation for tripping the rods. The CRS will review ITS 3.1.4, ROD GROUP ALIGNMENT LIMITS. For rod alignment the CRS will determine bank demand positions less than 200 steps if rod K2 is within 7.5 inches of the average of the individual rod positions in the bank. Entry to this will depend on how long the crew takes to identify rod K2 is stuck. Also, The CRS will need to determine if the rod is OPERABLE (trippable). The actions of the AOP will satisfy ITS 3.1.4 Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, the South Service Water Header will experience a break at the intake structure on the SW piping downstream of SW-6, SW Pump B Discharge Valve. The crew will take actions IAW AOP-022, Loss of Service Water, and will isolate the ruptured header and disable the service water pumps on the isolated header. This will result in the affected Emergency Diesel Generator being declared inoperable due to all the service water pumps supporting that EDG being disabled. The CRS will declare entry into ITS LCO 3.7.7, Condition A, due to one SW train inoperable. This LCO requires that the inoperable SW 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 />. The CRS will also declare entry into ITS LCO 3.8.1, Condition B, which requires the following: (1) Perform SR 3.8.1.1 for offsite circuit within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter (OP-604, Section 8.4.9, Emergency Diesel Generator Inoperability), (2) Declare required feature(s) supported by the inoperable DG inoperable when its required redundant feature(s) is inoperable within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> from discovery of Condition B concurrent with inoperability of redundant required feature(s), (3) Determine Operable DG is not inoperable due to common cause failure within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and perform SR 3.8.1.2 for Operable DG within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> and, (4) restore DG to Operable status within 7 days 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, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a partial loss of vacuum will be initiated. The crew will enter AOP-012, Partial Loss of Condenser Vacuum or Circulating Water Pump Trip. The crew will perform immediate operator actions and transition to Section A. Vacuum will stabilize with two vacuum pumps running. Leak location has been identified and determined to be a minor repair.
Once the Chief Examiner is satisfied with the crews actions, 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 Appendix D NUREG-1021, Rev. 9, Supp. 1
Appendix D Scenario Outline Form ES-D-1 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, Control Bank B rod K2 will be ejected. The crew will enter AOP-016, Excessive Primary Plant Leakage. PZR level and pressure will continue to lower and the crew will trip the reactor and enter EOP-E-0, REACTOR TRIP OR SAFETY INJECTION and perform immediate operator actions. During the Safety Injection both SI Pumps will fail to automatically start and will have to be manually started either by guidance in OMM-022 for automatic actions that should have taken place or IAW EOP-E-0 Attachment 1. SI-870 A & B, BIT OUTLET VALVES will fail to automatically open and will have to be manually opened either by guidance in OMM-022 for automatic actions that should have taken place or IAW EOP-E-0 . EOP-E-0 step 16 will have the crew transition to EOP-E-1, LOSS OF REACTOR OR SECONDARY COOLANT. EOP-E-1 step 17 will have the crew transition to EPP-8, POST LOCA COOLDOWN AND DEPRESSURIZATION. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, C S/G will rupture. This will be initiated when the crew enters EPP-8. The S/Gs should have feed water isolated to them at this time by closing V2-16A/B/C to maintain the S/G level control band. Foldout B is in effect IAW EPP-8 and the crew will transition to EOP-E-3, STEAM GENERATOR TUBE RUPTURE. The crew will isolate C S/G and cooldown and depressurize the RCS. The crew will stabilize from the cooldown but will not meet minimum subcooling and will be required to transition to EPP-17, SGTR WITH A LOSS OF REACTOR COOLANT. There are several transition points to EPP-17 based on subcooling, PZR level, and RCS pressure stable or rising. The crew may meet SI termination criteria based on their progress through the procedure, however, if SI is terminated they will not be able to maintain PZR level and will transition to EPP-17.
The Chief Examiner may terminate the scenario at any time after entry to EPP-17.

Description:
GP-003 Normal Plant Startup From Hot Shutdown to Critical Time Position Applicants Actions or Behavior EXAMINERS NOTE: The crew will assume the watch with the Shutdown Banks A & B at 225 steps performing a plant startup in accordance with GP-003, Normal Plant Startup From Hot Shutdown to Critical. The crew should be given adequate time to brief the evolution prior to entering the simulator. The crew will start at Section 8.2, Step 8.2.23.
GP-003 CRS Performs brief on Minimum of four inverse count rate ratio (1/M) data points are required on the approach to criticality..
NOTE: A minimum of four inverse count rate ratio (1/M) data points are required on the approach to criticality. The data points should be taken each time the count rate approaches a value that is approximately twice the previous stable data point. This is referred to as "doubling". The first data point, Reference Count Rate (CR0), is obtained after Shutdown Bank A and Shutdown Bank "B" have been fully withdrawn.
The Audio Count Rate VOLUME AND AUDIO MULTIPLIER should be adjusted as the count rate rises to maintain a distinguishable audible count rate.
WHEN Shutdown Bank A and Shutdown Bank B are fully withdrawn AND the count rate is stable, THEN RECORD the GP-003 BOP time and Reference Count Rate (CR0) on Attachment 10.2, Inverse Count Rate Ratio (1/M) Data and Plot Form.
Performs brief on step 8.2.24 through 8.2.27b being continuous action GP-003 CRS steps NOTE: The following FOUR steps, Steps 8.2.24 through 8.2.27.b, are continuous actions steps which remain in effect until the actions have been performed or plant conditions render the steps not applicable.
CAUTION A minimum of one decade overlap between Source Range and Intermediate Range Channels is required prior to blocking the Source Range Reactor Trip signals.

Description:
GP-003 Normal Plant Startup From Hot Shutdown to Critical Time Position Applicants Actions or Behavior It is NOT necessary to attempt to stabilize at exactly double the previous count rate, therefore the use of a "target count rate" (as applied to each doubling of the count rate) is intended to allow the Operator to stabilize the core as close as is practical to the "doubling" count rate without excessive rod motion.
APP-005-F2, ROD BOTTOM ROD DROP, will extinguish when Control Bank A is above 20 steps.
INPO SOER 07-1, Recommendation #2, makes the following statement: Reactivity changes during shift turnover or shift crew briefings are to be avoided. At RNP, this recommendation is implemented as follows:
- 1. Shift Turnover shall NOT be done unless the Reactor is stable AND EITHER (A) Shutdown Bank rod withdrawal has NOT commenced, OR (B) All Shutdown Bank rod withdrawal is complete with NO Control Bank rod withdrawal commenced or in progress.
- 2. The Reactor is stable at 10-8 amps. (OPEX 260129, NCR 527680)

- c. VERIFY the count rate stabilizes AND does NOT rise in an unexpected manner.
- d. IF criticality is indicated, THEN GO TO Section 8.3.
NOTE: Each successive reactivity addition will require less rod motion and a longer time for the count rate to stabilize. The NR-45 trace should be closely monitored and cross-checked against available instrumentation to determine when count rate has stabilized following each successive rod pull to double counts.
WHEN rod motion has been stopped AND count rate is stable, GP-003 RO THEN RECORD the required information on Attachment 10.2, Inverse Count Rate Ratio (1/M) Data and Plot Form.

SUMMARY
DESCRIPTION The crew will assume the watch with the plant at 75% steady state power. Operations Management has directed the plant power be reduced to 65% power to support valve testing.
The crew will reduce reactor power and turbine load IAW OP-105 to 65% to support valve testing.
On cue from the Chief Examiner, Control Bank C Rod D6 will experience and IRPI failure. The crew will enter AOP-001 and diagnose this as an IRPI due to no prompt drop. Rod D6 is in close proximity to NI-44 and no effects of a dropped rod are seen. The crew will transition to Section D. The CRS will need to apply ITS 3.1.7, Rod Position Indication. Once the Chief Examiner is satisfied, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Feedwater flow channel FT-477 fails High, affecting the automatic operation of Feedwater Regulating Valve FCV-478 for S/G A. The operator will have to take manual control of the FRV and restore the S/G to program level. The crew will perform the immediate actions for FT-477 failure IAW AOP-025, RTGB Instrument Failure, Section E.
The crew will perform the necessary transfer to the controlling channel and restore the FRV to automatic operation. The failed feedwater flow transmitter will be removed from service IAW OWP-026, FWF-2. The CRS will review ITS Table 3.3.1-1 Item 14 and determine it does not apply. Once the FRV returned to automatic and the Chief Examiner is satisfied, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PZR Pressure Transmitter PT-445 will fail Low, causing APP-003-D8 to alarm. Immediate actions of AOP-025, RTGB Instrument Failure, Section C will be performed by the crew. The CRS will verify that there are no applicable Tech Specs, PCV-456 is still operable because it can be manually opened and closed. Once the Chief Examiner is satisfied, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, The Inside Auxiliary Operator(IAO) will report a large oil leak on EDG A. This will render the EDG inoperable and will cause it to trip later in the scenario.
The CRS will also declare entry into ITS LCO 3.8.1, Condition B, which requires the following:
(1) Perform SR 3.8.1.1 for offsite circuit within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter (OP-604, Section 8.4.9, Emergency Diesel Generator Inoperability), (2) Declare required feature(s) supported by the inoperable DG inoperable when its required redundant feature(s) is inoperable within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> from discovery of Condition B concurrent with inoperability of redundant required feature(s), (3) Determine Operable DG is not inoperable due to common cause failure within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and perform SR 3.8.1.2 for Operable DG within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> and, (4) restore DG to Operable status within 7 days 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 stability of the plant and ITS compliance he may cue the next event On cue from the Chief Examiner, Feedwater Regulating Valve FCV-478 fails Open, this will lead to a reactor trip. The BOP will take manual control of FCV-478 to control S/G A water level, however, it will not work which will lead to the reactor being manually tripped. Upon the reactor trip, S/G B will become faulted in containment and the SUT will be lost.
Because of the Faulted S/G, a Safety Injection(SI) must be initiated. During the SI sequence, Service Water Pumps C and D will not start. The starting of these pumps is a Critical Task Appendix D NUREG-1021, Rev. 9, Supp. 1
Appendix D Scenario Outline Form ES-D-1 because only EDG B will be running. EDG A will have tripped due to the oil leak from before.
The crew will enter into EOP-E-0.
The Faulted S/G will cause CV pressure to rise above 10 psig which will cause an automatic CV Spray signal if the crew does not initiate one manually.

Description:
Power Reduction to 65% IAW OP-105 Time Position Applicants Actions or Behavior BOOTH OPERATOR: When directed, go to run on the simulator NOTE: Unloading of the unit should NOT exceed 5%/minute. Unloading of the unit can be stopped at any time by pressing the HOLD pushbutton. The HOLD lamp should illuminate, the GO lamp should extinguish, and unloading of the unit should be stopped. The SETTER should NOT be set to 0.0. If the Turbine is allowed to go to this setting without operator attention, all the governor valves could close and cause a turbine trip after a one minute time delay. During the load changes, GS-36, MANUAL GLAND SEAL DUMP may require throttling to maintain Gland Seal Pressure in the normal operating band of 3 to 6 psig.
CAUTION Although it is preferred to observe the effects of the initial boric acid addition prior to lowering Turbine load, it may be necessary to commence a rapid power reduction before the observed effects of any boric acid additions. In these situations, with rod Control in AUTOMATIC, Rod Control will drive the Controlling Bank of Rods to maintain Tavg on Tref. This will cause the Reactor Flux profile to go in the negative direction.
IF Reactor Power is near 100% at the time the rapid power change is commenced, this may cause Reactor Flux to go outside the Operating Band while less than 90% Power (or less than0.9 APL). IF this condition is established, APP-005-D6, Flux Warning / Status, and APP-005-E4, Flux Alarm, will both alarm.
IF a valid APP-005-E4 alarm is received while less than 90% Reactor Power (less than 0.9 APL), power reduction to less than 50% power will be required per ITS LCO 3.2.3. (NCR 306775)
IF EH Turbine Control is in OPER AUTO, THEN REDUCE turbine load as follows:
(1) PLACE the EH Turbine Control in the desired position:
- IMP IN (preferred)
- IMP OUT (if required for plant conditions)
(2) SET the desired load in the SETTER.

SUMMARY
DESCRIPTION The crew will assume the watch with the plant at 100% RTP.
On cue from the Chief Examiner, VCT Level Transmitter LT-115 will fail high. This will cause LCV-115A to divert all letdown flow to the CVCS HUTs and will cause LC-112, VCT Level Controller, to go to full output. LT-115 edge meter on the RTGB will indicate high. This failure will result in an VCT lowering, however, with LT-115 failed high there will be no automatic makeup. With no operator action this would result in the loss of Charging Pump suction. AOP-003, Malfunction of Reactor Makeup Control, will be implemented and LCV-115A will be overridden to the VCT until the VCT level control can be restored on the alternate channel. This will require that the alternate channel (LT-112) be selected for all control functions of VCT level.
Once AOP-003 actions are completed and when the Chief Examine is satisfied with the crew actions, the Chief Examiner will cue the next event.
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 1f, 1g, 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, B Charging Pump will trip. The crew will start a charging pump IAW APP-003-F5, CHG PMP MOTOR OVLD/TRIP. The CRS should reference ITS 3.4.17 and determine that the crew still has two operable charging pumps so condition A does not apply. Condition E for Seal injection to any RCP not within limit AND At least on charging pump OPERABLE does apply while no charging pumps were running. The crew may enter AOP-018, Reactor Coolant Pump Abnormal Conditions Section C for Loss of Seal Injection. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, B S/G will develop an 2.0 gpm tube leak. The crew will enter AOP-035, S/G TUBE LEAK. The crew may first enter AOP-016, EXCESSIVE PRIMARY PLANT LEAKAGE. This procedure would direct entry to AOP-035. AOP-035 can be entered by confirmed R-24, MAIN STEAM LINE N-16 MONITORS, leakage greater than or equal to 30 gpd. This would need to be validated by other radiation monitors or sampling by chemistry as R-24 is not technically in service at this time and is only used for trending. The magnitude of the leak will be 2.0 gpm which equates to 2880 gpd. This will be seen on R-24B initially and R-15, CONDENSER AIR EJECTOR GAS will start to trend up shortly after. ITS 3.4.13 has a primary to secondary leakage limit of 75 gpd in any one S/G. IAW AOP-035 the crew will declare a Appendix D NUREG-1021, Rev. 9, Supp. 1

When the Chief Examine is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, FCV-498 will fail high in automatic. The crew will enter AOP-010, Main Feedwater/Condensate Malfunction. Operator will perform immediate actions and take FCV-498 to manual to control level. Also, the crew will stop the load change IAW immediate operator actions. They will restore level to program level band and recommence the unit downpower with FCV-498 in manual control. When the Chief Examine is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner , The Turbine Governor valves fail closed. This will result in the crew initiating a manual reactor trip. The right trip button will not function but the left pushbutton will. Automatic reactor trip will not function if an automatic trip signal is received prior to initiation of the manual trip. On the reactor trip the B S/G PORV will fail 30% open. The crew will enter EOP-E-0, REACTOR TRIP OR SAFETY INJECTION, perform immediate operator actions and exit to EOP-ES-0.1, REACTOR TRIP RESPONSE.
At step 5 of EOP-ES-0.1 a 1000 gpm tube rupture will be initiated. The crew will return to EOP-E-0 and initiate safety injection. EOP-E-0 will direct entry to EOP-E-2, FAULTED STEAM GENERATOR ISOLATION. Step 4d checks the faulted S/G PORV closed and the RNO will direct locally isolating Instrument Air to the PORV. This will close the PORV and isolate the fault. Critical task due to impact on fission product barriers. Step 6 of EOP-E-2 will direct entry to EOP-E-3, STEAM GENERATOR TUBE RUPTURE. The crew will isolate B S/G, cooldown and depressurize the RCS and terminate safety injection.
The Chief Examiner may terminate the scenario at any time after safety injection has been terminated.

"ESFAS Instrumentation," Functions 1.a- f, for all initiation functions and requirements.
Reference LCO 3.4.2 RCS Minimum temperature for Criticallty. Crew determines all loop Tavg temperatures are greater than 530° F. When the Chief Examiner is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, C S/G PORV will fail open. The crew will enter AOP-025 Section I. The BOP will close the PORV by adjusting the controller potentiometer towards 0%
demand (raises the setpoint). The PORV control will be transferred to local control using and OWP-024 MS-4 will be implemented. The CRS will reference ITS 3.3.4, table B3.3.4-1 and determine that this specification is met by having the S/G safety valves operable.
When the Chief Examiner is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, PC-444Js pressure control band will shift causing pressure to not be kept in band(2220-2250 psig). The OAC will perform Immediate Actions of AOP-019, Malfunction of RCS Pressure Control. The OAC will take manual control of PC-444J and control pressure manually between 2220-2250psig. LCO 3.4.1 for RCS pressure <2223 psig (Standing Instruction 13-007) may be entered depending on how low pressure gets. Pressure will be controlled manually the rest of the scenario. When the Chief Examiner is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, Main Feedwater Pump B will trip. The BOP will perform Immediate Actions of AOP-010, Main Feedwater/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, an RCS leak in Containment will occur. The leak will start out at 30 GPM and gradually ramp up to 50 GPM. 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 A, will be entered due to unidentified leakage. Reduce leakage to within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Condition B equires 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 />. Once the crew has determined the leak rate and the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.

Appendix D Scenario Outline Form ES-D-1 On cue from the Chief Examiner, a non-isolable CCW leak will occur. This will require the crew to enter AOP-014, Component Cooling Water System Malfunction. The crew will try to make up to the CCW Surge Tank, however, the makeup will not overcome the amount leaking out. CCW surge tank will lower to <5% in which they will have a continuous action step to return to and trip the reactor. Upon initiating the reactor trip, the reactor will not trip(ATWS) and the crew will enter EOP-E-0, Reactor Trip or Safety Injection, and then transition immediately to FRP-S.1, Response to Nuclear Power Generation/ATWS. A LBLOCA will occur when the crew completes FRP-S.1. The crew will continue on with FRP-S.1 until it transitions them back to EOP-E-0 and then transition to EOP-E-1, Loss of Reactor Coolant or Secondary Coolant. Upon the LBLOCA, Phase A valves FP-249/249/256 and 258 will fail to auto close and have to be closed manually.
Phase B valve CVC-381 will fail to auto close and have to be closed manually. The crew will also enter FRP-P.1 due to the LBLOCA but will immediately exit due to the LOCA. AOP-014 is a concurrent AOP and an operator will be assigned to continue on with it once EOP-E-0 is complete.
Because there is no CCW available (due to the leak from before) the crew will have to transition from EOP-E-1 to EPP-15, Loss of Emergency Coolant Recirculation.
The Chief Examiner may terminate the scenario at any time after the crew has initiated makeup to the RWST.

SUMMARY
DESCRIPTION The crew will assume the watch with the plant at 50% RTP. They will maintain the current power level while repairs are being made to B MFP. The motor breaker has been racked out and the pump has been isolated and cleared for maintenance.
On cue from the Chief Examiner, HVH-5A, CRDM Cooling Fan, trips and HVH-5B fails to Auto-Start. The operator will verify the standby fan starts by manually starting HVH-5B from the RTGB in accordance with APP-010-A6, HVH-5A/B 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, RCP B will experience a #1 Seal Failure. The crew will enter AOP-018, Reactor Coolant Pump Abnormal Conditions. The crew will perform Attachment 2, RCP #2 Seal Leak Rate Calculation , monitor RCP Seal parameters, and inform Engineering of seal leakage. CRS will review ITS 3.4.17, CVCS, 3.4.13, RCS Operational Leakage, 3.4.4/3.4.5/3.4.6, RCS Loops, and 3.6.3, CV Isolation Valves. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, HVH-1 will develop a Service Water leak in containment. The crew will diagnose this by a rise in Containment sump level. They will receive APP-002-A8, HVH-1 WTR OUTLET LO FLOW alarm. They will also receive APP-002-E2, HVH CONDENSATE COLL alarm. APP-002-E2 requires an operator to acknowledge the alarm on the CMS panel or ITS 3.4.15 will apply. APP-002-A8 has a caution that an HVH unit may be operated up to 15 minutes without cooling water to the fan motor without damage. The APP will stop the fan and isolate cooling water. ITS LCO 3.6.6 Condition C applies and requires returning to operable within 7 days. The crew may refer to AOP-022 but this AOP does not address this event. When the Chief Examine is satisfied with the crew actions, the Chief Examiner will cue the next event.
On cue from the Chief Examiner, a loss of Instrument Bus #3 will occur due to the normal supply breaker on Inverter B trips. The crew will perform the immediate actions for the loss of Instrument Bus #3 IAW AOP-024, LOSS OF INSTRUMENT BUS. Once the cause of the loss of Instrument Bus #3 is determined the bus will be re-energized from its alternate power supply, MCC-8. Various automatic controllers will be returned to auto control. Rod control and Turbine control will be placed back in auto. The CRS will identify that ITS LCO 3.8.7, Condition A, is in effect while the normal supply breaker to Instrument Bus #3 is open. This LCO requires that the AC Instrument Bus Power Source be restored to Operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Additionally, ITS LCO 3.8.9, Condition B, was in effect while Instrument Bus #3 was de-energized. This LCO requires that the AC instrument bus subsystem be restored to Operable status within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
ITS LCO 3.4.9, Condition A may be entered if pressurizer level is allowed to rise above 63.3%.
The LCO requires that the plant be in Mode 3 with reactor trip breakers open within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. ITS LCO 3.4.1, Condition A may be entered if pressurizer pressure is allowed to lower below 2223 psig (Standing Instruction 13-007). This LCO requires that pressurizer pressure be restored within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or be in Mode 2 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. 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 steam leak will develop on the 72 header. The crew will commence a unit shutdown IAW GP-006-1, NORMAL PLANT SHUTDOWN FROM POWER OPERATION TO HOT SHUTDOWN OR AOP-038, RAPID DOWNPOWER. Once the Chief Examiner is satisfied with the crews actions, the Chief Examiner will cue the next event.
Appendix D NUREG-1021, Rev. 9, Supp. 1
Appendix D Scenario Outline Form ES-D-1 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. A steam explosion on the 72 header has damaged the MSIVs and they will fail to automatically close and cannot be manually closed. On the safety injection the FRVs will fail to automatically close and EOP-E-0 Attachment 1 will direct these valves to be closed manually. EOP-E-0 will direct entry to EOP-E-2, FAULTED STEAM GENERATOR ISOLATION. Step 2 of EOP-E-2 will direct entry to EPP-16, UNCONTROLLED DEPRESSURIZATION OF ALL STEAM GENERATORS. EPP-16 will isolate all S/Gs. The crew will throttle AFW flow to each S/G to 80-90 gpm. This will cause CSF for Heat Sink to turn red.
The crew will enter FRP-H.1 and transition back to procedure and step in effect due to the red path being caused by operator action. The crew will transition to FRP-P.1, Response to Imminent Pressurized Thermal Shock. This procedure also throttles AFW flow to a minimum of 80 gpm to each S/G so if the crew transitions to FRP-P.1 prior to throttling flow in EPP-16 it will still get done.
The Chief Examiner may terminate the scenario at any time after the SI pumps have been secured in FRP-P.1.
