Rev 5 KA Rejection List Justification:

1. RO Tier 1 Group 2 Original KA: 036 Fuel handling accident / 8, AK 1.03 - Knowledge of the operational implications of the following concepts as they apply to fuel handling incidents -

Indications of approaching criticality (IR 4.0/4.3)

Justification for Rejection: After spending many hours on this K/A, it has been determined that identifying plausible distractors is very difficult. Wolf Creek has criticality monitors for the Spent Fuel Pool and SR NIs for the vessel. If it is stated that indications are rising so what could be the cause, then identifying plausible distractors becomes very difficult. Recommend rejecting this KA and resampling per the resampling criteria. SEB 3/24/15 Replacement Methodology: Since there are 12 evolutions (or systems for Tier 2) for this Tier/Group that have not been sampled, and the random number selected was 5, 076 High Reactor Coolant Activity / 9, was chosen. With only 5 Ks and As, and the random number selected was 2, AK2 was chosen. Since there is only one K/A with an Importance Rating over 2.5, AK 2.01 was chosen.

2. RO Tier 2 Group 1 Original KA: 008 Component Cooling Water / 8, A 2.05 - Ability to (a) predict the impacts of the following malfunctions or operations on the CCWS, and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations - Effect of loss of instrument and control air on the position of the CCW valves that are air operated. (IR 3.3/3.5)

Justification for Rejection: This K/A has little impact to the plant. There are only three total air operated valves in the CCW system. One on the CCW heat exchanger that regulate temperature that fail closed to provide full cooling. The CCW system has no low temperature alarms. The other is on the Letdown Heat exchanger to control letdown temperature. There are no low letdown temperature alarms either. This valve fails open to allow for full cooling of the letdown water. Since the Off Normal procedure for CCW malfunctions only deals with pumps running, overall system flow, leak, and head tank level, there are no items to write a question over which have procedural guidance.

Recommend rejecting this KA and resampling per the resampling criteria. SEB 3/16/15.

Replacement KA: 008 Component Cooling Water / 8, A2.04 Ability to (a) predict the impacts of the following malfunctions or operations on the CCWS, and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations: PRMS alarm (IR 3.3/3.5) 1

Rev 5

3. RO Tier 2 Group 1 Original KA: 078 Instrument Air, 2.1.19 - Conduct of ops - Ability to use plant computers to evaluate system or component status.

Justification for Rejection: This K/A asks to monitor IA with the plant computer. Our plant computer has very limited inputs from IA and if that is the only source of information looked at diagnosing status of IA would be very difficult. Alarms are about all we have and if I give the alarm for an air compressor trip is makes the question very low cognitive level. Recommend resampling for this tier and group. SEB 3/27/15 Replacement KA: 078 Instrument Air , A3.01 - Ability to monitor automatic operation of the IAS including: Air pressure.

4. SRO Tier 3 Original KA: G 2.1.15 - Knowledge of administrative requirements for temporary management directives, such as standing orders, night orders, operations memos, etc.

Justification for Rejection: This KA applies to both SRO and ROs at Wolf Creek and the procedure for this is very generic in nature to allow for variations in what is needed. An SRO only question here is not practical. Recommend resampling.

Replacement KA: 2.1.23 Ability to perform specific system and integrated plant procedures during all modes of plant operation. The replacement KA was chosen using the resampling criteria for same Tier and Topic.

5. SRO Tier 2 Group 2 Original KA: 033 2.4.3 Spent Fuel Pool Cooling - Identify post-accident instrumentation.

Justification for rejection: This does not apply to Wolf Creek. There is no post-accident instrumentation for fuel pool cooling.

Replacement KA: 014 A 2.02 - Rod position indication - Ability to predict the impacts of the following malfunctions or operations on the RPIS and based on those on those predications use procedures to correct control or mitigate the consequences of those malfunctions or operations - loss of power to the RPIS

6. RO Tier 1 Group 1 Original KA: 015 2.1.45 - RCP malfunctions - Ability to identify and interpret diverse indication to validate the response of another indication.

Justification for rejection: This KA combination is not allowed by NUREG 1021 Replacement KA: 015 2.1.19 - RCP malfunctions - Ability to use plant computers to evaluate system or component status.

7. SRO Tier 1 Group 2 Original KA: 032 AA 2.04 - Satisfactory SR/IR overlap.

Justification for rejection: Overlap with the RO test Replacement KA: 033 AA 2.10 - TS limits if both IR channels have failed

8. SRO Tier 3 Original KA: 2.4.23 - Knowledge of the bases for prioritizing emergency procedure implementation during emergency operations.

Justification for rejection: Cant write a SRO Level question from this topic.

Replacement KA: 2.4.37 - Knowledge of the lines of authority during implementation of the emergency plan.

9. SRO Tier 3 Original KA: 2.1.32 - Ability to explain and apply system limits and precautions.

Justification for rejection: Overlap with the RO test.

Replacement KA: 2.1.2 - Knowledge of Operator responsibilities during all modes of plant operation.

Appendix D Scenario Outline Form ES-D-1 SCENARIO # 1 NARRATIVE Turnover: Scenario starts out at 100% power MOL. No equipment is out of service.

Event 1: NCP flow control valve fails low (BG FK-462). The failure will cause the running charging pump (NCP) to lower flow. If the ATC does not take action when lowering flow is first noted then annunciator 41A, SEAL INJ TO RCP FLOW LO, and 42A, CHG LINE FLOW HILO alarm. The ATC will place BG FK-462 in manual and restore charging flow to normal. The SRO enters and directs 42A.

Event 2: Main feedwater header pressure detector AE PI-508 failure high. The failure causes the MFP speed to slow. The BOP will take manual control of MFP Turbine Master Speed Controller, FC SK-509A, and restore feed pump speed to normal value and recognize that AE PI-508 has failed high. SRO enters and directs OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment B, STEAM OR FEEDWATER HEADER PRESSURE CHANNEL MALFUNCTION. Annunciators 108B through 111B may alarm if the BOP does not recognize AE PI-508 failing in a timely manner.

Event 3: PZR level channel BB LI-459 fails hi over 30 seconds. This will cause multiple alarms and PZR indicated level to rise. The crew diagnoses and identifies the level channel failure and the SRO enters and directs OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment J, PZR LEVEL CHANNEL MALFUNCTION. The SRO enters TS 3.3.1, REACTOR TRIP SYSTEM INSTRUMENTATION, Table 3.3.1-1, Function 9 Cond A - Immediately, and Cond M - 72 hrs.

Event 4: Dropped rod. Control rod H8 will suffer a stationary gripper failure and fall into the core. The SRO enters and directs OFN SF-011, REALIGNMENT OF DROPPED RODS AND ROD CONTROL MALFUNCTIONS. Pressure transient from the dropped rod results in the SRO entering T.S. 3.4.1 RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits, Condition A. The ATC and BOP coordinate actions to stop rod motion, reduce turbine load per GEN 00-004, Attachment F, and prepare to recover the dropped rod. The SRO enters T.S. 3.1.41, Rod Group Alignment Limits Cond B - 1 hr. QPTR and AFD will be monitored to determine if the T.S. limit is exceeded.

Event 5: Rod ejection resulting in a LOCA. The crew should diagnose the rod ejection through DRPI indications and the RCS leak indications. The SRO should direct reactor trip and manual initiation of safety injection, which will automatically occur if no actions are taken. The SRO enters and directs EMG E-0, REACTOR TRIP OR SAFETY INJECTION.

Event 6: Turbine fails to trip in auto, and one MSIV fails to close in auto. The BOP is expected to recognize that the turbine failed to trip in automatic and manually trip the turbine as his immediate action.

This action will be directed by EMG E-0, REACTOR TRIP OR SAFETY INJECTION, step 2 RNO.

(Note: With the turbine failing to auto trip AND one MSIV failing to auto close the component failure for the BOP will be mitigated by either manually tripping the turbine or manually closing the one open MSIV to prevent uncontrolled RCS cooldown.)

Event 7: NB01 bus faults and locks out. The NB01 bus will lockout when the safety injection signal is actuated. NE01 output breaker, NE HIS-25, will not close when the EDG is up to speed and voltage as normal. The ATC should recognize that EDG NE01 is running and report the condition to the SRO. If the crew does not recognize that the EDG is running, it will trip on high jacket water temperature. The bus fault causes a loss of all A train safety related equipment.

(NOTE: Per OFN NB-030, LOSS OF AC EMERGENCY BUS NB01 (NB02), Foldout Page Item 2, IDLE EMERGENCY DIESEL CRITERIA, IF an Emergency Diesel is running unloaded and cooling water can not be established within 30 minutes, THEN stop affected Emergency Diesel. If the crew does not stop the EDG before it trips on high jacket water temperature, then a comment on their performance should be documented.)

Appendix D Scenario Outline Form ES-D-1 Event 8: The B train CCP fails to auto start from the SIS (manual start available).

CT 1: Establish flow from at least one Charging pump by the completion of EMG E-0, Attachment F.

(NOTE: B CCW pump trips on reactor trip with an auto start of the D CCW pump, this is to check if the crew ensures a CCW pump is running in the same train as the CCP that will be started)

Event 9: Following the reactor trip the TDAFWP fails to start due to broke trip throttle valve and B MDAFW pump shaft shears. During the performance of EMG E-0, REACTOR TRIP OR SAFETY INJECTION, the crew will diagnosis a loss of all AFW due to the B MDAFWP shaft shear, loss of NB01 (loss of A MDAFWP), and the failure of the TDAFWP to start due to the broken trip throttle valve. The crew will complete the required actions of E-0 and then transition to EMG FR-H1, RESPONSE TO LOSS OF SECONDARY HEAT SINK. Subsequent actions start the NonSafety Aux Feed Pump (NSAFP).

CT 2: Establish AUX feed flow (from the NSAFP) to at least ONE intact S/G at a flow rate great enough that core exit temperatures are stable or decreasing AND level in at least ONE S/G is increasing, prior to bleed and feed criteria being met (3 of 4 Wide Range level less than 12% [28% w/

adverse containment conditions].

Crew transitions from EMG FR-H1 to E-0 then to EMG E-1, LOSS OF REACTOR OR SECONDARY COOLANT. The crew will continue in E-1 until SI is reset after which the scenario can be terminated.

Appendix D Scenario Outline Form ES-D-1 SCENARIO # 2 NARRATIVE Initial conditions: Rx is at 5.1% Power, EOL, with no equipment OOS.

Turnover: Continue with GEN 00-003, step 6.11.2.1, () WITHDRAW control rods in MANUAL, to establish Reactor Power stable between 5% and 10% while continuing with this procedure.

Event 1: The crew will continue to raise power towards 10% power using GEN 00-003, HOT STANDBY TO MINIMUM LOAD, step 6.11.2.

Event2: Loop A Primary RTD (411C - TCOLD) fails high. The crew will mitigate using OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment L, NARROW RANGE RTD MALFUNCTION. No immediate actions are required due to the low power level. SRO will direct the procedure. The ATC will select out the failed channel. The SRO enters T.S. 3.3.1, REACTOR TRIP SYSTEM INSTRUMENTATION, Table 3.3.1-1, Functions 6 and 7, Condition A - Immediately, Condition E - 72 hrs.

Event 3: A S/G level channel (AE LI-551) fails low. The crew will mitigate using OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment F, S/G LEVEL CHANNEL MALFUNCTION. The BOP will initially take manual control of the MFW regulating bypass valve and control S/G level. Automatic control will be restored once an alternate control channel is selected. The SRO enters T.S. 3.3.1, REACTOR TRIP SYSTEM INSTRUMENTATION, Table 3.3.1-1, Function 14, Condition A - Immediately, Condition E - 72 hrs., and T.S. 3.3.2, ENGINEERED SAFETY FEATURES ACTUATION SYSTEM INSTRUMENTATION, Table 3.3.2-1, Functions 5.c And 6.d, Condition A - Immediately, Condition D - 72 hrs., and Condition I - 72 hrs.

Event 4: Power Range Channel (SE NI-43) failure upscale to 80% over 15 seconds. The ATC will check no runback in progress and then ensure rods are in manual (rods should be in manual due to power level). The crew will diagnose the failure and enter OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment R, POWER RANGE NEUTRON FLUX CHANNEL MALFUNCTION, and bypass the failed channel. The SRO enters T.S. 3.3.1, REACTOR TRIP SYSTEM INSTRUMENTATION, Table 3.3.1-1, Functions 2, 3, 6, 18.b, 18.c, 18.d, And 18.e, Condition A - Immediately, Condition D - 12 hrs., Condition E

- 72 hrs., Condition S - 1 hr., and Condition T - 1 hr.

Event 5: B S/G ARV fails open (manual control available). The BOP will either notice that the ARV is open and inform the SRO and close the valve in manual, or, if he does not see the open ARV will lower main turbine load to lower reactor power to less than 100%. The crew may enter OFN AB-041, STEAMLINE OR FEEDLINE LEAK, to mitigate the event. There will be no alarms for this event. The SRO determines that the ARV is operable per T.S. 3.7.4 bases, i.e., capable of fully opening and closing with no seat leakage.

Event 6: A S/G Fault inside Containment and MSIVs fail to Auto close. The crew recognizes CTMT conditions changing, and power rising. Due to the rapid transient, the crew may not have opportunity to manually trip the reactor before automatic actuation occurs. The crew enters and performs EMG E-0, REACTOR TRIP OR SAFETY INJECTION. Following the completion of Immediate Action step 2, the BOP should recognize that Foldout Page Item # 3, Faulted S/G Isolation Criteria, applies and closes MSIVs, isolates feed flow to A S/G, ensuring AFW flow is maintained to the unaffected S/Gs.

CT 1: Isolate feed flow into and steam flow from the faulted SG before ANY RCS Cold Leg temperatures reach 240°F or before transition to EMG C-21.

Event 7: SIS fails to auto initiate. The crew must recognize the requirement for SIS and manually initiate both trains. This should be performed by the ATC. The crew transitions to EMG E-2, FAULTED STEAM GENERATOR ISOLATION, for the mitigation of the faulted S/G.

CT 2: Manually actuate SI (SB HS-27 & 28) after auto SI actuation criteria are met prior to transition out of EMG E-0, step 4.

The crew completes EMG E-2 and transitions to EMG ES-03, SI TERMINATION. The scenario may be terminated by the chief examiner after the crew stops all but one CCP at step 5.

Appendix D Scenario Outline Form ES-D-1 SCENARIO # 3 NARRATIVE Turnover: Scenario starts with the unit at 100% power. Service Water pump B is tagged out for maintenance, not expected to return this shift. The crew is to maintain 100% power. A Thunderstorm warning is in effect. T.R 3.7.8, Service Water System, Condition A, has been entered due to the B service water pump.

Event 1: Service Water pump C trips. The Low Flow pump cannot increase service water pressure enough - PRA #3. The crew places both ESW trains in service IAW ALR 00-008B, SERV WTR PRESS HILO. SRO enters T.R 3.7.8, Service Water System, Conditions A, B for the loss of two Service Water pumps and C for NOT being capable of supplying both ESW trains from Service Water. Condition A was already in effect for Service Water pump B.

Event 2: Main feedwater regulating valve (AE FK-530) will fail closed in automatic over a 2 minute period. The crew mitigates the event using ALR 00-110C, SG C FLOW MISMATCH. The BOP places AE FV-530 in manual and restores level to program as directed by the SRO. The BOP maintains manual control of C steam generator level. There is no off-normal procedure associated with this failure.

Event 3: PZR pressure channel (BB PI-457) fails low. The crew performs OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment K, PZR PRESSURE MALFUNCTIONS. The ATC places the PZR master controller in manual, controls pressure, and then selects an alternate control channel. The SRO directs placing the PZR master controller back in auto once pressure is stabilized. SRO enters T.S. 3.3.1, Reactor Trip System Instrumentation, Conditions A, E, and M, and 3.3.2, Engineered Safety Feature Actuation System Instrumentation, Conditions A, D, and L.

Event 4: HP Turbine 1st stage pressure (AC PT-505) fails low causing rods to step in. The ATC places rods in manual after verifying no turbine runback. The ATC or BOP identifies the failure and the crew enters OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment D, TURBINE IMPULSE PRESSURE CHANNEL MALFUNCTION, to select an alternate channel for control. SRO enters TS 3.3.1, Reactor Trip System Instrumentation, Condition A and T.

Event 5: Abnormal condenser vacuum requiring load decrease using OFN AF-025, UNIT LIMITATIONS, ATTACHMENT F, LOSS OF CONDENSER VACUUM. Crew reduces turbine loading using OFN MA-038, RAPID PLANT SHUTDOWN.

Event 6: 500 gpm SGTR in B S/G - PRA#5. At the time of the reactor trip a Loss of off-site power-PRA#1 (Drives CT 1 to start at least one EDG). Additionally, the MSIVs fail open and cannot be closed (Drives EMG C-31, SGTR WITH LOSS OF REACTOR COOLANT - SUBCOOLED RECOVERY DESIRED procedure entry). The crew recognizes RCS pressure and pressurizer level trending down and B S/G MFRV controller trending closed as level trends up. RM-11 indicates S/G process radiation trending up on GE RE-92. The crew may enter OFN BB-07A, STEAM GENERATOR TUBE LEAKAGE, which will eventually direct manually tripping the reactor and initiating Safety Injection. The Crew performs EMG E-0, REACTOR TRIP OR SAFETY INJECTION. A loss of offsite power will occur when the reactor is tripped (PRA#1). Additionally, the MSIVs fail open and cannot be closed.

Event 7: Both EDGs fail to auto start. The ATC starts both EDGs per immediate action step 3 of EMG E-0, REACTOR TRIP OR SAFETY INJECTION.

CT 1: Manually start at least one EDG prior to transitioning to EMG C-0, LOSS OF ALL AC POWER, at EMG E-0, step 3 RNO.

Page 4 of 6 Rev 6

Appendix D Scenario Outline Form ES-D-1 Event 8: B MDAFW throttle valve (AL HK-9A) fails open. Once the crew determines the B S/G is ruptured the BOP isolates the S/G per foldout page of EMG E-0, REACTOR TRIP OR SAFETY INJECTION. The BOP stops the A MDAFWP and dispatches an operator to locally isolate AL HV-9. If the BOP fails to stop the MDAFW pump, the local operator will report that the isolation valve cannot be closed.

Otherwise the local operator isolates AL HV-9 and the BOP restarts the A MDAFWP.

CT 2: Terminate AFW to the Ruptured B S/G within 18 min of safety injection initiation.

The crew continues in EMG E-0, transitions to EMG E-3, STEAM GENERATOR TUBE RUPTURE, and then to EMG C-31, SGTR WITH LOSS OF REACTOR COOLANT - SUBCOOLED RECOVERY DESIRED. After the crew resets SIS the scenario may be terminated by the Lead Examiner.

The crew diagnoses the failure and enters OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment R, POWER RANGE NEUTRON FLUX CHANNEL MALFUNCTION. ALR 00-078A, 82A, and 83C will actuate and the Crew could use any of these to get to the OFN. The crew bypasses the channel and restores rods to auto. The SRO enters TS 3.3.1, Reactor Trip System Instrumentation, Conditions A, D, E, S, and T and T.R. 3.3.17, REACTIVITY CONTROL AND POWER DISTRIBUTION ALARMS, Condition D.

Event 2: Steam generator D pressure channel (AB PI-545A) fails high. The crew should diagnose steam flow from the D S/G indicating higher than the other S/G or level rising. ALR 00-111B, SG D LEV DEV, actuates. The BOP places the MFRV in manual and controls level. The SRO enters the ALR and/or OFN SB-008, INSTRUMENT MALFUNCTIONS, Attachment C, SG PRESSURE CHANNEL MALFUNCTION. Attachment A, STEAM FLOW CHANNEL MALFUNCTION, may be entered first on the high flow indication, which will reference back to Attachment C. An alternate channel will be selected and automatic control restored. The SRO enters TS 3.3.2, Engineered Safety Features Actuation System Instrumentation, Conditions A and D.

Event 3: Loss NN02 Instrument bus. The SRO directs OFN NN-021, LOSS OF VITAL 120 VAC INSTRUMENT BUS, Attachment B, LOSS OF VITAL INSTRUMENT BUS NN02 (WHITE TRAIN). The ATC selects the alternate PZR pressure channel for control, adjusting pressure control as needed. The BOP selects the red train instruments for S/G level and steam flow. Once the alternate channels are selected, the NN02 bus may be reenergized. SRO enters T.S. 3.8.7, Inverters Operating, Condition A, and T.S. 3.8.9 Distribution Systems - Operating, Condition C. These apply as long as the breaker NN0201 is open and the NN bus is unavailable. Protection and Control interlocks are verified, however, T.S. 3.3.1 and 3.3.2 are not entered.

Event 4: Loss of Wolf Creek-Benton 345 kV offsite line. The crew enters OFN AF-025, UNIT LIMITATIONS, Attachment A, UNIT LOAD LIMITS, reducing unit load to less than 800 MWE NET (845 MWE GROSS). SRO enters TR 3.8.1, Offsite Power System Transmission Network, Condition A.

Event 5: Inadvertent SI B Train. The crew enters EMG E-0, REACTOR TRIP OR SAFETY INJECTION.

The crew actuates the second train of SI, resets SI, isolates the BIT inlet and outlet valves and then continues with the procedure.

CT 1: Isolate BIT inlet and outlet valves within 8 minutes from initiation.

Event 6: Loss of all AC. LOOP w/ B EDG failing to start in auto and manual. (PRA). The crew enters EMG C-0, LOSS OF ALL AC POWER. The crew is able to restore power from the SBO diesels to either NB bus using OFN NB-030, LOSS OF AC EMERGENCY BUS NB01 (NB02). The OFN will direct the crew to SYS KU-121 (122), ENERGIZING NB01 (NB02) FROM STATION BLACKOUT DIESEL GENERATORS.

Only one safeguards bus can be energized by the SBO diesels.

CT 2: Energize either NB01 or NB02 using SYS KU-121 or SYS KU-122 before the following are met:

RCS subcooling - Less Than or Equal to 30°F [45°F]

OR

Pressurizer level - Less Than or Equal to 6% [32%]

The crew energizes an NB bus then continues with EMG C-0, LOSS OF ALL AC POWER, and then transitions to EMG CS-01, LOSS OF ALL AC POWER RECOVERY WITHOUT SI REQUIRED. After the crew resets CISA the scenario may be terminated by the Lead Examiner.
