Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Facility: Wolf Creek Vendor: WEC Exam Date: 8/2009 Exam Type: R Examination Outline Cross-reference: Level RO SRO Tier # 2 Group # 1 K/A # 103 K1.08 Importance Rating 3.6 Knowledge of the physical connections and/or cause-effect relationships between the containment system and the following systems: SIS, including action of safety injection reset Proposed Question: RO Question # 1 Which ONE of the following describes the operation of Containment Isolation Phase A (CISA)?

A. ONLY actuated on Containment Pressure HIGH-1. May be physically reset independently of any other safeguards actuation signal.

B. ONLY actuated on Containment Pressure HIGH-1. Contacts in the SI reset circuitry prevent Phase "A" reset prior to SI reset.

C. Actuated on any SI actuation. Contacts in the SI reset circuitry prevent Phase "A" reset prior to SI reset.

D. Actuated on any SI actuation. May be physically reset independently of any other safeguards actuation signal.

Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible because CISA does actuate on HIGH-1. However, any SI actuation signal will also initiate CISA.

B. Incorrect. Plausible because CISA is always reset after SI in accordance with plant procedures, so it is logical to believe that it cannot physically be reset prior to SI.

C. Incorrect. Plausible because the first half is true, and also because of the same reason that option B is plausible, due to EOP usage.

D. Correct.

• The plant is at 55% power.

• BB LT-459 is the controlling Pressurizer Level Transmitter.

• BB LT-459 fails high instantaneously.

Assuming NO action by the crew, which ONE of the following describes the initial observable effect on Chemical and Volume Control System (CVCS) and Pressurizer Heaters?

A. Charging flow lowers; Pressurizer Backup Heaters energize B. Charging flow lowers; Pressurizer Backup Heaters de-energize C. Letdown isolates; Pressurizer Backup Heaters de-energize D. Letdown isolates; Pressurizer Backup Heaters energize Proposed Answer: A Explanation (Optional):

A. Correct. 5% level deviation HIGH will cause backup heaters to energize. Charging flow lowers because the controlling channel indicates a HIGH deviation from program setpoint.

3 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet B. Incorrect. Charging lowers but heaters will energize. Plausible because heaters eventually will de-energize when the backup channel is reduced below 17%.

C. Incorrect. Letdown will isolate and heaters will de-energize at a later time when backup channel is low (<17%) if no action is taken. This would immediately happen only for a low failure of the controlling channel.

D. Incorrect. Letdown will isolate later when backup channel is low if no action is taken.

Heaters do energize for this event based on +5% deviation.

• The plant is operating at 100% power.

• Discharge of Waste Monitor Tank No. 1 (THB07B) is in progress.

• The following alarms are received approximately 15 seconds apart:

• ALR 00-061B, PROCESS RAD HI

• ALR 00-061A, PROCESS RAD HI-HI

• ALR 00-109F, LIQ RADWASTE TROUBLE

• ALR 00-061C, PROCESS RAD MON FAIL

• Report from Liquid Process Control Panel HB-115 indicates that the alarm received is RADIATION MONITOR

• Control Room indication for Liquid Radwaste Discharge Process Monitor, HB RE-18, is OFF-SCALE LOW.

Which ONE of the following describes the status of the liquid waste discharge for these conditions?

A. The discharge is automatically terminated; Liquid release may be resumed ONLY after HB RE-18 is returned to OPERABLE status.

B. The discharge is automatically terminated; Liquid release may be resumed upon satisfactory completion of actions required by AP 07B-003, Offsite Dose Calculation Manual, even if HB RE-18 remains INOPERABLE.

11 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet C. The discharge continues and must be manually terminated; Liquid release may be resumed ONLY after HB RE-18 is returned to OPERABLE status.

D. The discharge continues and must be manually terminated; Liquid release may be resumed upon satisfactory completion of actions required by AP 07B-003, Offsite Dose Calculation Manual, even if HB RE-18 remains INOPERABLE.

Proposed Answer: B Explanation (Optional):

A. Incorrect. Plausible because automatic termination does occur as indicated by HI HI rad and the local waste panel alarm (RAD MON). Also, release may NOT continue unless actions described in options B and D are taken.

B. Correct. Automatic termination occurs on HI HI radiation. Release may not continue unless rad monitor is repaired or ODCM actions are taken.

C. Incorrect. Plausible because of same reason as option A, and also because a radiation monitor failure by itself will not close the release path. Applicant must also know that a failure of the rad monitor does not cause a HI HI alarm by itself.

D. Incorrect. Plausible because actions are correct, and also because the applicant must understand what a rad monitor failure does, and that a HI HI radiation alarm will cause automatic valve closure, independent of monitor failure.

• A Loss of Off-Site power occurred.

• "A" EDG started but its output breaker will NOT close.

• Subsequently, a large steamline break resulted in a Safety Injection.

• All other equipment operated as designed and NO other abnormal conditions have occurred.

Which ONE of the following describes the operation of the Emergency Load Sequencer associated with the failed EDG?

A. Does NOT perform load shed or equipment loading sequence.

B. Load shed sequence is initiated by the Shutdown Sequencer upon receipt of loss of power; LOCA Sequencer sheds additional loads upon receipt of the SI signal; equipment loading sequence is NOT initiated.

C. LOCA sequencer will block the Shutdown Sequence load shed sequence when SI actuates, but load shedding will not occur until the EDG output breaker is closed.

D. Load shed sequence is initiated by the Shutdown Sequencer upon receipt of loss of power; LOCA Sequencer sheds additional loads upon receipt of the SI signal; equipment loading sequence occurs, but NO loads will be energized.

Proposed Answer: B 14 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Incorrect. Load shedding is initiated on the UV signal. Plausible because Load Sequence is not initiated until the EDG output breaker is closed.

B. Correct. It is logical to believe that the sequencer operates when power is lost or SI is actuated. However, the actual load sequencing will not occur until the bus is re-energized. Load shedding is performed when the UV signal is received, then again when the SI signal is received.

C. Incorrect. Plausible because the LOCA sequencer does block the operation of the Shutdown Sequencer, but ONLY after EDG output breaker closure.

D. Incorrect. Plausible because the bus will be de-energized, so the fact that equipment will not run is true. The applicant must also understand that the sequences start from EDG output breaker closure.

MDAFW "A" MDAFW "B" TDAFW Discharge Pressure Discharge Pressure Discharge Pressure A. unaffected decreases increases B. increases increases decreases C. decreases unaffected increases D. unaffected unaffected decreases Proposed Answer: A Explanation (Optional):

A. Correct. Flow from TDAFW will be lowered. MDAFW "B" discharge valve (smart valve 25 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet MOV) will throttle open to maintain 300 GPM to the SG. The position of the valves on the discharge piping will cause pump discharge pressure from TDAFW Pump to rise as the resistance to flow rises as the discharge valve closes.

B. Incorrect. Plausible because it is logical to assume both MDAFW Pumps are affected if TDAFW Pump discharge is closed. In this case, closing the valve raises TDAFW discharge pressure. The effect is the opposite of actual.

C. Incorrect. Plausible because this is similar to correct answer, except for the fact that MDAFW Pump "B" supplies SG "D". The applicant may confuse AFW alignment.

D. Incorrect. Plausible because it is logical to assume both MDAFW Pumps are affected if TDAFW Pump discharge is affected. In this case, the discharge pressure effects would be correct if the valve being operated was on a discharge line common to all 3 pumps, and if the valve was opened to raise flow.

Which ONE of the following identifies the correct ESF actuation logic for the remaining Containment pressure channels?

A. Safety Injection - 1/2; Containment Spray - 1/3 B. Safety Injection - 1/2; Containment Spray - 2/3 C. Safety Injection - 1/3; Containment Spray - 1/3 D. Safety Injection - 1/3; Containment Spray - 2/3 Proposed Answer: B Explanation (Optional):

A. Incorrect. SI is normally 2 of 3 logic for Containment Pressure and CS is 2 of 4. When a protection channel that feeds both actuations is removed from service, bistables are tripped in all cases except for the AUTO CS actuation. (Placed in BYPASS) Thus, 31 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet AUTO SI will occur if either of the two remaining bistables trip, but AUTO CS still needs two of the three remaining channels to trip.

B. Correct. See distractor explanations and attached references.

C. Incorrect. SI is 1 of 2. CS is 2 of 3. Plausible because PZR Pressure SI actuation is 2 of 4 logic, and the applicant may confuse the logic with the 2 of 3 logic provided by High CTMT pressure SI actuation. The applicant may also believe that all bistables, including CS actuation, are tripped when a channel has failed.

D. Incorrect. SI is 1 of 2 after removing a channel from service, because Containment Pressure High-1 provides 3 channel inputs to SI actuation. Plausible because Low PZR Pressure SI input would be 1 of 3.

Assuming that RCS and flux distribution parameters remain on program/target, as power is raised to 100%, how will the over-temperature (OT) and over-power (OP) differential temperature (DT) Reactor Protection setpoints change?

OTDT setpoint OPDT setpoint A. increase stay the same B. decrease decrease C. decrease stay the same D. stay the same increase Proposed Answer: C Explanation (Optional):

A. Incorrect. Plausible because the OPDT setpoint does remain the same, and the applicant may confuse the fact that the OTDT setpoint decreases with the term

'increase' meaning the actual value is closer to setpoint.

34 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet B. Incorrect. The OTDT setpoint does decrease. The OPDT setpoint never increases from its nominal value. It will, however decrease if T-avg deviates above its nominal 100% power program value. Since T-avg at 80% power is less than 100% power, the OPDT setpoint will be at its nominal full power value and thus, will not change from 80 to 100% power assuming T-avg stays on program.

C. Correct. Since T-avg at 80% power is less than 100% power, the OPDT setpoint will be at its nominal full power value and thus, will not change from 80 to 100% power assuming T-avg stays on program. The OTDT setpoint, on the other hand can increase or decrease from its nominal value. Since program T-avg will increase approximately 5 more degrees, the trip setpoint will become more limiting, decreasing to its nominal full power value.

D. Incorrect. OTDT decreases as referenced above in C. The OPDT setpoint never increases from its nominal value. It will, however decrease if T-avg deviates above its nominal 100% power program value SY 1301200 Rev 6 Technical Reference(s): (Attach if not previously provided)

A. Main Turbine failed to trip; manually trip the turbine, verify generator output breakers and exciter field breaker open after approximately 30 seconds, and verify that plant parameters stabilize while continuing in EMG E-0.

B. Main Turbine failed to trip; immediately trip the turbine, open the generator output breakers and exciter field breaker, and verify SI has actuated.

C. A LOCA has occurred; verify SI has actuated and immediately open the generator output breakers and exciter field breaker.

D. A LOCA has occurred; verify SI has actuated and verify that the generator output breakers and exciter field breaker open within 30 seconds after the trip.

52 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible because generator output breakers being closed (but for >30 seconds) after a trip can be a sign of turbine trip circuitry failure. Additionally, RCS temperature is lowering but not fast enough to indicate a turbine trip failure.

Containment pressure indicates a LOCA has occurred.

B. Incorrect. Plausible for same reasons as A, except that action is different. Turbine trip would be required if that was the failure, but generator output breakers open on a time delay to assist coastdown.

C. Incorrect. Failure is correct, and action is plausible because generator load is indicated, but applicant must know that generator output breakers do not open until after a time delay. If breakers do not open, then they will be manually opened D. Correct. See explanations above.

A. Reactor will trip; stabilize the plant using EMG E-0, Reactor Trip or Safety Injection, and refer to the appropriate OFN procedure to locally operate the Turbine Driven AFW Pump, if required.

B. Reactor will trip; stabilize the plant using EMG E-0, Reactor Trip or Safety Injection, and refer to the appropriate OFN procedure to place EDG "B" in LOCAL/MANUAL due to loss of field flash capability.

C. The reactor will remain at power; EDG "B" must be placed in LOCAL/MANUAL in accordance with the appropriate OFN procedure due to loss of field flash capability.

D. The reactor will remain at power; Turbine Driven AFW Pump will start due to loss of power and must be shut down manually using the appropriate OFN procedure.

Proposed Answer: B 61 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Incorrect. Loss of NK04 will cause loss of field flash for EDG "B". Plausible because TDAFW is affected by loss of NK02. The reactor will trip because feedwater isolation occurs, and at 100% power, SG LO-LO level will cause a trip.

B. Correct.

C. Incorrect. Plausible because there is no direct reactor trip, and loss of control power to the reactor trip breaker does not cause it to open. The applicant must determine that feedwater isolation will result in a reactor trip at this power level. Actions for EDG "B" are correct.

D. Incorrect. Plausible because there is no direct reactor trip, and loss of control power to the reactor trip breaker does not cause it to open. The applicant must determine that feedwater isolation will result in a reactor trip at this power level. Actions for TDAFW are incorrect, since a loss of NK04 does not affect TDAFW, but loss of NK02 does.

Proposed Answer: B Explanation (Optional):

72 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet A. Incorrect. While it is true that LCO 3.6.6 requires that two trains of Containment Spray be Operable in Modes 1-4, and that the plant is in Mode 4, the LCO has no action requirements within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The applicant would have to consider that LCO 3.0.3 applies if only 1 train was required and none were available in a lower mode B. Correct. LCO 3.6.6 requires that two trains of Containment Spray be Operable in Modes 1-4. The plant is in Mode 4, and therefore Trains A and B of CS are required.

Action is required (Restore Operability) within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

C. Incorrect. In Mode 4 both trains of CS are required to be Operable. To say that the LCO is satisfied by only the A Train of CS being Operable is an error, but a plausible misconception related to reduced operability requirements in lower modes.

D. Incorrect. Technical Specification Table 1.1-1 defines the Modes of Operation. Mode four is defined as RCS Temperature < 350oF > 200oF. This would be correct if RCS Temperature were < 200oF.

A. Steam Dumps are automatically controlling Tavg above the normal Tavg setpoint; EMG ES-02 directs manual Steam Dump to condenser to restore Tavg to setpoint.

B. Steam Dumps are automatically controlling Tavg above the normal Tavg setpoint; EMG ES-02 directs manual control of feed flow to stabilize RCS temperature at setpoint.

C. Steam Dumps have closed due to P-12 actuation; EMG ES-02 requires reset of Steam Dumps to regain control of secondary heat removal.

D. Steam Dumps have closed due to P-12 actuation; EMG ES-02 directs manual control of feed flow and manual operation of steam dumps/ARVs to control RCS temperature at setpoint.

86 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible because this could occur if P-4 (RTB) wasn't actuated to place steam dumps in plant trip mode. They would act as though they are in load reject mode and operate in a 2 degree dead band. Action would be logical if this were the failure.

B. Incorrect. Plausible because this could occur if P-4 (RTB) wasn't actuated to place steam dumps in plant trip mode. They would act as though they are in load reject mode and operate in a 2 degree dead band. Action would be logical if this were the failure, as raising feed flow would cause reduction in Tavg. (Same as A)

C. Incorrect. Failure mode is correct because the Tavg mode selects Auctioneered High Tavg. Although Delta T indicates low power, it is because Tcold failed high in this case.

Plausible because bypassing P-12 may be performined for an RCS cooldown, but in this case, ES-02 does not provide this guidance because Tavg will be controlled at a higher value than where the P-12 interlock will actuate.

D. Correct.

D. BOTH the Electrical Trip System AND the Mechanical Trip System actuate to provide turbine trip function; Intermediate Stop Valves AND Intercept Valves close.

Proposed Answer: D 89 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Incorrect. While the main trip is provided by the electrical trip system in this case, cross-trips are actuated to cause the mechanical trip system to operate as well.

Plausible because the mechanical trip system is typically identified with mechanical overspeed trip and manual trip from the front standard. Also, logical that intercept valves could remain open because the stop valves will interrupt flow to the LP turbine from MSRs. The intercept valves can be used to control the turbine, and are in the same casing as the stop valves.

B. Incorrect. While the main trip is provided by the electrical trip system in this case, cross-trips are actuated to cause the mechanical trip system to operate as well.

Plausible because the mechanical trip system is typically identified with mechanical overspeed trip and manual trip from the front standard. Also, second part correctly describes operation of the valves.

C. Incorrect. The first part is correct, as cross-trips will actaute the mechanical governor.

Second half is incorrect but plausible due to same reason as option A D. Correct.

• An event has occurred causing a Reactor Trip and Safety Injection Actuation.

• RCS pressure is 1450 psig and lowering.

• Containment pressure is 8.5 psig and rising.

Which ONE of the following describes the status of RCP seal leakoff under these conditions?

A. All RCP seal leakoff is isolated; #2 seal leakoff is directed to the PRT.

B. RCP #1 seal leakoff is directed to the PRT; #2 seal leakoff is directed to the RCDT.

C. RCP #1 seal leakoff is directed to the VCT; #2 seal leakoff is directed to the PRT.

D. All RCP seal leakoff is isolated; #2 seal leakoff is directed to the RCDT.

Proposed Answer: B Explanation (Optional):

A. Incorrect. All RCP leakoff is not isolated. RCP #1 seal leakoff isolates but is directed to PRT via relief valve, since there is a DP from the seal through the relief valve.

Plausibility enhanced because #2 seal does drain to the RCDT, not the PRT.

B. Correct.

94 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet C. Incorrect. Plausible because normally #1 seal is directed to VCT, and applicant must infer that Containment Isolation Phase A (CISA) has occurred since SI is actuated, which would isolate the normal #1 seal leakoff flowpath. Applicant may confuse seal leakoff flowpaths and believe that #2 seal is directed to the PRT.

D. Incorrect. Same description as option A and C. #1 seal is directed to PRT via relief, even though isolation to VCT does occur when CISA actuates. #2 seal is directed to RCDT under either condition, whether normal or CISA conditions.

• ECCS failures required entry to EMG FR-C1, Response to Inadequate Core Cooling.

• The crew is evaluating the operation of Hydrogen Recombiners.

• Containment pressure is 37 psig.

• Containment Hydrogen Concentration is 2.7%.

Which ONE of the following describes whether the Hydrogen Recombiners will be placed in operation, and the reason why?

A. Place Hydrogen Recombiners in service; Containment Hydrogen concentration is above the level where risk of an explosion would result in unacceptable containment pressure rise.

B. Place Hydrogen Recombiners in service; Containment Hydrogen concentration is within the range where Recombiners can effectively reduce containment hydrogen concentration, but below the range where ignition of hydrogen may occur.

C. DO NOT place Hydrogen Recombiners in service; Containment Hydrogen concentration is above the level where risk of an explosion would result in unacceptable containment pressure rise.

96 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. DO NOT place Hydrogen Recombiners in service; Containment Hydrogen concentration is below the range where Recombiners can effectively reduce containment hydrogen concentration, and risk of explosion is minimal.

Proposed Answer: B Explanation (Optional):

A. Incorrect. EMG FR-C1 background doc describes operation of Recombiners. If concentration is between 0.8% and 3.0%, Recombiners are placed in service. This is due to minimal risk of explosion and unwanted containment pressure increase.

Plausible because the applicant may believe that recombiners must be placed in service due to the higher risk of explosion as H2 concentration rises. Incorrect because at this concentration, risk is lower, especially with 37 psig in containment.

B. Correct. At 4% hydrogen, ignition may occur in dry air. The recombiners are placed in service due to this consideration. Typical flammability limit discussions start at 3%

hydrogen concentration, but with containment pressure at 37 psig, ignition is highly unlikely.

C. Incorrect. Plausible because the range is 0.8% to 3.0%. The applicant must understand the plant condition and can easily confuse the applicant, who may believe that Recombiners are started only if hydrogen concentration is below 0.8% to prevent ignition.

D. Incorrect. Plausible because the applicant may know that one setpoint in EMG FR-C1 is 3%, and can confuse that setpoint with being the limit for Recombiner operation. The option is logical if the applicant determines that 3% is the cutoff.

• The plant tripped from 100% power due to a loss of all feed flow.

• Multiple failures caused a loss of all AFW.

D. Feed only ONE SG at less than or equal to 35,000 lbm/hr; Limit thermal stresses to SG components.

110 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible since to satisfy the CSF status tree 270K is required based on these plant conditions (NR levels in all SGs < 6%). The applicant who is not familiar with the criteria for a hot-dry SG is likely to select this distractor.

B. Incorrect. Flow rate is plausible as described above. ERG and plant procedures discuss maintaining symetric cooling, so this is plausible however the HOT-DRY criteria precludes feeding all SGs.

C. Incorrect. First part is correct as it is the guidance for HOT-DRY SGs. The second part is incorrect but plausible since 35K gpm is the minimum verifiable AFW flow at WCNOC; candidate is likely to associate 35K as correct for this reason (e.g. EMG C-21 establishes 30K to maintain minimum heat sink). For these plant conditons the concern is for feeding excessively not feeding a minimum amount.

D. Correct. EMG FR-H1 limits feeding to only ONE SG at a time and limits flow to 35K lbm/hr. The ERG basis is to limit thermal stresses to the SG.

At this point (~1100 psig RCS pressure) RCS inventory is forced out of the break, which is in the top of the pressurizer, resulting in PZR level indication rising.

A. Insert control rods in Manual; to insert negative reactivity by the most direct manner possible.

B. Insert control rods in Manual; to ensure that the only heat input to the RCS is from RCPs.

C. Place EHC Pumps in PULL-TO-LOCK; to prevent uncontrolled cooldown of the RCS.

D. Place EHC Pumps in PULL-TO-LOCK; to minimize secondary makeup requirements.

Proposed Answer: C Explanation (Optional):

A. Incorrect. Plausible because these are immediate actions in EMG FR-S1, which is a transition from the immediate actions of E-0. In E-0, attempt to manually trip reactor, but rods are driven in EMG FR-S1. Reason is correct and logical for any reactor trip.

B. Incorrect. Plausible because these are immediate actions in EMG FR-S1, which is a transition from the immediate actions of E-0. In E-0, attempt to manually trip reactor, but rods are driven in EMG FR-S1. Reason is correct manual trip of reactor.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet initiates; Prevents EDG overload by allowing starting current from other equipment to decay.

Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible because AFW pumps do start on an AFAS signal after the reactor trips. The loss of power occurred prior to the AFAS signal being received, so the AFAS signal would be blocked by either Shutdown or LOCA Sequencer until the time delay is satisfied. AFW start is not a condition assumed for all Category III or IV events, although it is assumed for some.

B. Incorrect. The loss of power occurred prior to the AFAS signal being received, so the AFAS signal would be blocked by either Shutdown or LOCA Sequencer until the time delay is satisfied. Reason is correct.

Proposed Question: RO Question # 48 Given the following:

• A LOCA outside containment has occurred.

• The crew is performing the actions in EMG C-12, LOCA Outside Containment.

• CVCS has been verified isolated.

Which ONE of the following actions will be the FIRST to be attempted to isolate the break and which indication is used to determine if the leak has been isolated in accordance with EMG C-12?

A. Isolate RHR piping; RCS pressure is monitored, because SI flow will repressurize the RCS with the break isolated.

B. Isolate RHR piping; Pressurizer level is monitored, because with the break isolated, RCS inventory will rapidly rise.

C. Isolate the BIT Injection line; RCS pressure is monitored, because SI flow will repressurize the RCS with the break isolated.

D. Isolate the BIT Injection line; Pressurizer level is monitored, because with the break isolated, RCS inventory will rapidly rise.

Proposed Answer: A 131 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Correct. CVCS is checked while re-energizing RHR Hot Leg suction valves to ensure they are closed. The first isolation occurs in low pressure piping, which is more likely to break than the BIT Injection line, which is designed for higher pressure.

B. Incorrect. Pressurizer level may be an indication of recovering inventory, but if it was off-scale low, it may take a long time to determine if the break was isolated, so it is not used for EMG C-12.

C. Incorrect. Plausible because the BIT is checked, and connected to RCS. BIT is just lower priority than RHR. Parameter is correct, as in A.

D. Incorrect. See descriptions above, same determination.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet FT-510 lowering LT-517 stable D. FT-512 lowering FT-510 lowering LT-517 stable Proposed Answer: C Explanation (Optional):

A. Incorrect. Plausible because it is logical that extra fluid into the SG would raise level, but the control system would respond to maintain level. At 100% power, the mismatch will not be large, but based on plant conditions, it would be seen on SGWLC.

B. Incorrect. Plausible because if the applicant believes that steam flow would rise, it is logical to believe that feed flow would attempt to match it, and level would rise.

Incorrect because the phenomena of a tube rupture would not be to increase steam flow, but to limit feed flow to maintain level with the RCS inventory contributing to SG mass.

C. Correct. Level will be maintained at program by SGWLC. With a large SGTR, feed flow would lower to limit SG level increase, creating a slight steam flow-feed flow mismatch.

D. Incorrect. Steam flow would be maintained by steam demand and be fairly equal to all other SGs. A tube rupture would not be large enough to appreciably change steam flow. Plausible because feed flow and SG level response are correct, and because a logical connection can be made to increased steam flow based on RCS inventory entering the SG.

• RHR Pump "A" discharge flow begins fluctuating up to 1000 GPM.

• RCS temperature is rising slowly.

• The crew enters OFN EJ-015, Loss of RHR Cooling.

• RCS level indicates the following:

• Loop level indicates 16 inches.

• Tygon Tube level indicates 14 inches.

A. CCW to RHR Heat Exchanger valve EG HV-101 failed closed; locally open the valve to restore cooling.

B. CCW to RHR Heat Exchanger valve EG HV-101 failed closed; reduce RHR flow to stop cavitation.

C. Containment Sump level indication rising; reduce letdown flow to restore minimum RCS level.

137 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. Containment Sump level indication rising; reduce RHR flow to stop cavitation.

Proposed Answer: D Explanation (Optional):

A. Incorrect. Level is below minimum required for reduced inventory operations, so leakage must be occurring somewhere in the system. Plausible because loss of CCW could cause enough RCS heatup in reduced inventory to cause cavitation, but it would take some time, and also the action is correct (per procedure) for the indication given.

B. Incorrect. Level is below minimum required for reduced inventory operations, so leakage must be occurring somewhere in the system.

• The plant is at 100% power.

• The controlling pressurizer pressure instrument fails high.

Which ONE of the following describes the response of the plant PRIOR to the first protective action that occurs?

A. Total RCP Seal Leakoff flow will rise slightly; unaffected OTDT channel setpoints rise.

B. Total RCP Seal Leakoff flow will rise slightly; unaffected OTDT channel setpoints lower.

C. Total RCP Seal Leakoff flow will lower slightly; unaffected OTDT channel setpoints rise.

D. Total RCP Seal Leakoff flow will lower slightly; unaffected OTDT channel setpoints lower.

Proposed Answer: D Explanation (Optional):

A. Incorrect. Seal leakoff flow is driven by seal design, and will change with differential pressure across the #1 seal. The RCS is depressurizing due to open PORV and spray valves, and VCT pressure is constant. Therefore, differential pressure goes down, resulting in less impetus for flow. OTDT setpoint lowers due to the lowering RCS 140 REV SUBMIT

A. Correct. An alternate train pump is first started, inventory is maintained to the system so that time is available to isolate the leak, and the alternate train is placed in service. In this case, the leak is on the service loop, so the next action is to open ESW supply to CCW.

B. Incorrect. It is only required if both CCW trains are unavailable (<15%).

C. Incorrect. Isolating this component is not addressed until the end of the procedure, although it will be performed for a service loop leak at some point prior to identification of the leak.

D. Incorrect. This is part of foldout page action when the CCW Surge Tank lowers to 15%due to a service loop leak. More plausible because letdown is a service loop component.

D. TRM 3.1.9 applies for boration injection subsystems; action to initiate plant shutdown must be taken immediately.

Proposed Answer: C 152 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Incorrect. TS 3.5.2 does apply when one CCP is out of service, but when a second pump is out of service, the limitations of the TS are exceeded, and 3.0.3 will be applied.

Plausible because this TS is related and is actually in effect in the initial condition prior to the failure.

B. Incorrect. Plausible because operability of RWST may be affected since it supplies flow to the suction of CCPs (operability based on ability to perform intended function) Action time is incorrect but provided to give balance to distractors.

C. Correct. TS 3.5.2 only allows for one train of ECCS without full flow. In this case there are 2 trains affected and cannot obtain full flow equivalent to one train, so 3.0.3 must be applied. TS 3.0.3 requires initiation of plant shutdown within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

D. Incorrect. When a boration subsystem is lost, this TRM item applies. Action C for loss of 2 boration subsystems applies, and action is required immediately. However, action to initiate plant shutdown is not required immediately.

• The plant is in Mode 6.

• Core Alterations are in progress.

• While inserting a fuel assembly in the assigned Spent Fuel Pool rack, the following indications are observed:

• Fuel Building Area Rad Monitor indications are rising on SD RI-37 & 38.

• Fuel Building Atmosphere Monitor GG RIC-27 is in HI-HI alarm.

• Fuel Building Atmosphere Monitor GG RIC-28 is trending up but NOT in alarm.

• The crew enters OFN KE-018, Fuel Handling Accident.

Proposed Question: RO Question # 59 Given the following:

• A LOCA has occurred.

• Due to several component failures, the crew was required to perform EMG C-11, Loss of Emergency Coolant Recirculation.

• The Crew is now entering EMG FR-Z1, Response to High Containment Pressure.

• Containment pressure is 40 psig and STABLE.

• THREE (3) Containment Fan Coolers are in service.

• BOTH Containment Spray Pumps were STOPPED while performing EMG C-11.

• RWST Level is 10% and lowering slowly.

Which ONE of the following describes the reason for the current configuration and strategy for reducing Containment Pressure?

A. Both Containment Spray Pumps are off because Containment pressure has reached a stable value during performance of EMG C-11. START both Containment Spray Pumps in accordance with EMG FR-Z1 because Red CSF conditions take precedence over ECA actions.

B. Both Containment Spray Pumps are off because Containment pressure has reached a stable value during performance of EMG C-11. Perform ONLY the EMG FR-Z1 actions that do NOT conflict with or undo the action taken in C-11. Two Containment Coolers will provide adequate depressurization to meet the Containment Safety Function requirements.

163 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet C. Both Containment Spray Pumps were turned off in EMG C-11 because the number of Containment Coolers operating ensured that Containment design pressure will not be exceeded. Do NOT perform actions of EMG FR-Z1 until the RWST LOLO level alarm is clear and Containment Spray Pumps may be restarted. Ensure all other automatic actions related to containment isolation have occurred as required.

D. Both Containment Spray Pumps were turned off in EMG C-11 because the number of Containment Coolers operating ensured that Containment design pressure will not be exceeded. OPERATE Containment Spray Pumps in accordance with the guidance in EMG C-11, as directed by EMG FR-Z1.

Proposed Answer: D Explanation (Optional):

A. Incorrect. EMG FR-Z1 Step 3 RNO says operate Pumps IAW EMG C-11. Plausible because a red condition exists on the Containment CSF, and it is logical to start all spray pumps. First part is plausible because EMG C-11 directs stopping Containment Spray as as soon as it is no longer necessary. Stabilizing Containment pressure is a logical indicator that Spray is no longer needed, but incorrect because the parameter is not evaluated for securing spray. Only RWST level, Containment Cooler operation, and Containment pressure are evaluated.

B. Incorrect. First part is plausible because EMG C-11 directs stopping Containment Spray as as soon as it is no longer necessary. Stabilizing Containment pressure is a logical indicator that Spray is no longer needed, but incorrect because the parameter is not evaluated for securing spray. Only RWST level, Containment Cooler operation, and Containment pressure are evaluated. 2 Containment Coolers will NOT meet safety function at a containment pressure of 40 psig. However, this option is plausible because the action is consistent with the action that will be taken.

C. Incorrect. First part is correct. At 10% RWST level and 40 psig Containment pressure, the only reason that both containment spray pumps would be stopped is if there were at least 3 containment coolers running when EMG C-11 was performed. Plausible because RWST LO-LO level is a logical point to be able to run pumps taking suction from RWST, and the containment isolation actions would actually be performed regardless of plant condition.

166 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Proposed Answer: C Explanation (Optional):

A. Incorrect. Tref will not be lowering because plant efficiency is changing. Minor changes in vacuum will not affect first stage impulse pressure on the HP turbine.

B. Incorrect. Tref will not be rising for same reason as option A. Tref derived from First Stage pressure and that will not be changing, since control valve position is not changing.

C. Correct.

D. Incorrect. Turbine on load limit will not prevent load from dropping due to changes in efficiency. Plausible because applicant may assume that load will be held stable, and therefore, rod position.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. An Accidental radioactive release may be occurring. SG Blowdown Discharge Pump must be stopped to terminate the release.

Proposed Answer: D Explanation (Optional):

A. Incorrect. SG BD Isolation valves should be closed on HI HI Rad from RE-92.

Plausible because the SG Blowdown Monitors are not in alarm, and applicant can easily misunderstand all inputs to valve closure circuitry. It is not unusual for sample valves to be closed, as they would only be open when a sample is being drawn. The OFN will be used based on the HI-HI Rad alarm response.

B. Incorrect. SG BD Isolation valves should be closed on HI HI Rad from RE-92.

Plausible because the SG Blowdown Monitors are not in alarm, and applicant can easily misunderstand all inputs to valve closure circuitry. It is not unusual for sample valves to be closed, as they would only be open when a sample is being drawn. The OFN will be used based on the HI-HI Rad alarm response, but the step is an 'OR' step, not an 'AND' step for the various monitors.

C. Incorrect. SG Blowdown Valves should have automatically closed on High Radiation D. Correct. The alarm on BE RE-52 should automatically stop the SG Blowdown Discharge Pump. Since Pump is still running and SG Blowdown Isolation Valves are open, a release may be occurring which may be stopped by stopping the SG Blowdown Discharge Pump..

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Proposed Answer: D Explanation (Optional):

A. Incorrect. Plausible because one level instrument is reading slightly high, (reference leg leak causes high indication) but the controlling instrument is low, causing the alarm. If the controlling instrument is low, then Charging will be rising to increase level. Charging flow control output will be rising if demand for flow is rising. Output lowering is plausible because CVCS has a reverse acting controller for letdown backpressure. Additionally, the pressurizer level master controller provides input to the controller on low level.

B. Incorrect. Same reason as option A for plausibility of cause, and in this case, charging flow control is correct.

C. Incorrect. Correct failure, and plausible because the applicant may confuse controller output. Since the charging flow controller fails open, the applicant may assume that output lowers when valve opens.

Proposed Question: RO Question # 66 With the plant operating at power, a hydrogen leak on the Main Generator has reduced hydrogen pressure from 75 psig to 60 psig.

Which ONE of the following represents a set of initial Turbine Generator operating parameters that, if remaining unchanged by the leak, are UNACCEPTABLE for continued operation of the Main Generator?

(Reference Provided)

A. Turbine Load of 1100 MWe; AND Reactive Load of (+)475 MVARs OUT.

B. Turbine Load of 1200 MWe; AND Reactive Load of 350 (+)MVARs OUT.

C. Turbine Load of 1100 MWe; AND Reactive Load of (-)475 MVARs IN.

D. Turbine Load of 1200 MWe; AND Reactive Load of (-)350 MVARs IN.

Proposed Answer: C Explanation (Optional):

183 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet A. Incorrect. When the initial conditions are plotted on Figure 1 - Generator Performance Curve, the intersecting point is below the limiting Hydrogen Pressure line of the post-leak condition (i.e. 60 psig). Therefore, it is acceptable to operate at this point for both initial and after-leak conditions.

B. Incorrect. When the initial conditions are plotted on Figure 1 - Generator Performance Curve, the intersecting point is below the limiting Hydrogen Pressure line of the post-leak condition (i.e. 60 psig). Therefore, it is acceptable to operate at this point for both initial and after-leak conditions.

C. Correct. According to SY1504502 (p21-22, 47; Rev 010), Figure 8, the Generator Capability Curve, shows the allowable generator MWe load as a function of hydrogen pressure and reactive power. Reactive power is indicated by either power factor or as leading/lagging VAR flow. As an example, this curve shows that with a load of 1200 MW and a hydrogen pressure of 75 psig, the limit for lagging MVARS is 625 (i.e. the intersecting point of Reactive Load and Turbine Load is below the 75 psig Hydrogen Pressure line). According to OFN AF-025 (p1; Rev 27), the Unit Limitations procedure delineates the limitations on the Turbine Load for operating during various restrictive conditions (such as Reduced Generator Cooling Capability). According to Step 4 of OFN AF-025 (p5; Rev 27), the operator must determine, Using Figure 1 - Generator Performance Curve, that Turbine Generator parameters are Acceptable, and if NOT, employ a corrective strategy in accordance with Attachment G. According to OFN AF-025 (p32; Rev 27), Figure 1 - Generator Performance Curve, this is the only set of initial conditions that are Acceptable initially (i.e. below the 75 psig Hydrogen Pressure line)

AND Unacceptable after the stabilized leak pressure of 60 psig (i.e. above the 60 psig Hydrogen Pressure line).

D. Incorrect. When the initial conditions are plotted on Figure 1 - Generator Performance Curve, the intersecting point is below the limiting Hydrogen Pressure line of the post-leak condition (i.e. 60 psig). Therefore, it is acceptable to operate at this point for both initial and after-leak conditions.

• N41 = 6.1%

• N42 = 4.7%

• N43 = 4.9%

• N44 = 4.9%

• N41 = 4.8%

• N42 = 4.8%

• N43 = 5.8%

• N44 = 5.6%

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. Mode 2; AND Mode 2.

Proposed Answer: C Explanation (Optional):

A. Incorrect. 1st part wrong, 2nd part correct. This is plausible if the operator incorrectly believes that only one Power Range instrument reading greater than 5% is sufficient to satisfy the criteria for entry into Mode 1.

B. Incorrect. 1st part wrong, 2nd part wrong. This is plausible if the operator incorrectly believes that Mode 1 is entered when at least 3 of 4 Power Ranger channels are equal to or greater than 5%.

C. Correct. 1st part correct, 2nd part correct. According to LO1732700 (p18-20; Rev 7), A MODE shall correspond to any one inclusive combination of core reactivity condition, power level, average reactor coolant temperature, and reactor vessel head closure bolt tensioning specified in Table 1.1-1 with fuel in the reactor vessel. Technical Specifications identifies the six operational Modes in Section 1.1 (Definitions), page 1.1-

7. According to Table1.1-1, the difference between Mode 1 and Mode 2 is determined based on the existing % Rated Thermal Power (%RTP). When %RTP is greater than 5%, the plant is in Mode 1; and when %RTP is less than or equal to 5%, the plant is in Mode 2. According to SY1301501 (p35; Rev 11), there are four Power Range instruments designated N41, N42, N43 and N44. Because of this, some further definition of the Mode Change criteria is necessary to account for variations between the Power Range Instruments. According to LO1732700 (p18-20; Rev 7) and GEN 00-003 (p46; Rev 72) Mode 1 is entered when 2 of 4 power range channels indicate greater than 5% power, and according to LO1732700 (p18-20; Rev 7) and GEN 00-005 (p32; Rev 58), Mode 2 is entered when 3 of 4 power range channels indicate less than or equal to 5%. Based on this, it can be seen that initially the plant is in Mode 2, with only N41 indicating greater than 5%; and subsequently, the plant is in Mode 1, with both N43 and N44 greater than 5%.

D. Incorrect. 1st part correct, 2nd part wrong. This is plausible if the operator incorrectly believes that Mode 1 is entered when at least 3 of 4 Power Ranger channels are greater than 5%.

• A Steam Generator Tube Rupture has occurred on SG "B".

• The crew has performed all actions of EMG E-3 up to the step to commence depressurization of the RCS.

• All equipment is functioning as designed.

A. CLOSED with controller in Manual; prevent radioactive release to atmosphere.

B. CLOSED with controller in Manual; ensures minimum RCS subcooling will be maintained when RCS depressurization is initiated.

C. Set at 1160 psig with controller in AUTO; prevent uncontrolled radioactive release due to SG safety valve lifting.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet A. Incorrect. Plausible because it is logical to maintain valve closed but controller will not be in manual. Reason is correct.

B. Incorrect. Same reason as option A, and additionally, reason is plausible because if the ARV stuck open on a ruptured SG, the depressurization would also cause depressurization of the RCS. This would result in loss of RCS subcooling.

C. Correct.

D. Incorrect. Correct for status of valve, but reason is incorrect. Plausible because valve would be placed in manual and closed if it stuck open below 1160 psig, but this is not the reason that the valve is placed in AUTO. The remainder of the steps for SG isolation are correct for this reason.

Proposed Question: RO Question # 71 With the plant at 100% power, the following conditions exist:

• A .5 gpm Steam Generator Tube Leak develops.

• GE RE-92, Condenser Off Gas Monitor, enters the high-high alarm condition (Red).

• The operating crew enters the appropriate Off-Normal procedure.

Which ONE of the following will provide the quickest indication of the Steam Generator with the leaking tube?

A. A local radiation survey of the steam lines.

B. The Steam Line Radiation Monitors readings (AB RE 111-114).

C. The Steam Generator Blowdown Sampling Monitor reading (SJ RE-02).

D. The Steam Generator Blowdown Process Monitor readings (BM RE-25).

Proposed Answer: A Explanation (Optional):

A. Correct. According to OFN BB-7A (p6; Rev 8), there are four primary means to identify the leaking Steam Generator; (1) unexpected increase in level (which is NOT plausible with a .5 gpm tube leak), (2) radiation from any SG steamline radiation monitor, (3) radiation from any SG steamline survey, or (4) radiation from any SG sample.

196 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet According to BD-OFN BB-7A (p14; Rev 1), subsequent recovery actions require that the operator be able to distinguish between the intact Steam Generators and the Steam Generator with the tube leak to minimize primary to secondary leakage. With small leaks it may be necessary to use radiation monitors or to sample. The operator is instructed to try to identify the affected Steam Generator early in this guideline to allow the time necessary to sample if the leak is small. This implies that the use of installed or portable radiation monitors are preferred to the more time consuming sample. Since there is no flow through any of the Blowdown monitors, or steam flow by the Steam Line Monitors, the local survey of the steam lines will provide information necessary to identify the Steam Generator with the leaking tube.

B. Incorrect. According to LO1407300 (p28-29; Rev 11), the Steam Line Monitors continuously indicate, detect, and alarm the AREA of a steam release for gamma radiation. These monitors are also known as "plume" monitors or "shine" monitors. A SLM is mounted adjacent to each Main Steam Line Atmospheric Relief Valve (ARV),

and will provide indication within the Control Room when there is flow in this line. Under the stated conditions, there is no flow through the atmospheric relief valves, and no abnormal radiation will be indicated.

C. Incorrect. According to LO1407300 (p24-25; Rev 11), GE RE-92 will actuate a BSPIS and close BM HV-1, 2, 3, 4 CTMT isolation valves and BM HV-5, 6, 7, and 8 sampling isolation valves. According to LO1407300 (p24-25; Rev 11), this BSPIS signal will also cause flow to be lost through SJ RE-02 and BM RE-25. This is plausible because according to LO1407300 (p16-17; Rev 11), SJ RE-02 will help plant personnel diagnose a steam generator tube leak, according to OFN BB-7A (p12; Rev 8), under certain circumstances the setpoints of SJ RE-02 can be readjusted, and the operator may incorrectly believe that it is, or can be made, available.

D. Incorrect. According to LO1407300 (p24-25; Rev 11), GE RE-92 will actuate a BSPIS and close BM HV-1, 2, 3, 4 CTMT isolation valves and BM HV-5, 6, 7, and 8 sampling isolation valves. According to LO1407300 (p24-25; Rev 11), this BSPIS signal will also cause flow to be lost through SJ RE-02 and BM RE-25. This is plausible because according to LO1407300 (p17; Rev 11), BM RE-25 will help plant personnel diagnose a steam generator tube leak, according to OFN BB-7A (p12; Rev 8), under certain circumstances the setpoints of BM RE-25 can be readjusted, and the operator may incorrectly believe that it is, or can be made, available.

• The plant at 100% power.

• A fire occurs in the plant.

• The operating crew enters OFN KC-16, Fire Response.

• PORV BB PCV-455A is observed to be spuriously opened.

• Attempts to close the PORV Block Valve from the control room are unsuccessful.

D. Containment; AND/OR Control Building; AND/OR Auxiliary Building.

Proposed Answer: D Explanation (Optional):

199 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet A. Incorrect. This is plausible because the PORV is located within the Containment, and the operator may incorrectly believe that a fire in the Control Building and/or Auxiliary Building will NOT cause the PORV to open spuriously and its Block Valve to fail to close electrically.

B. Incorrect. This is plausible because the PORV is located within the Containment, and the operator may incorrectly believe that a fire in the Auxiliary Building will NOT cause the PORV to open spuriously and its Block Valve to fail to close electrically.

C. Incorrect. This is plausible because the PORV is located within the Containment, and the operator may incorrectly believe that a fire in the Control Building will NOT cause the PORV to open spuriously and its Block Valve to fail to close electrically.

D. Correct. According to OFN KC-016 (p2; Rev 18), taking manual actions to close a failed open PORV during a fire is a time critical task that must be performed within 5 minutes. These actions are identified in Attachments B, C and D. According to OFN KC-016 (p5; Rev 18), Attachment B identifies actions that could be taken during a fire in the Auxiliary Building, Attachment C identifies actions that could be taken during a fire inside Containment, and Attachment D identifies actions that could be taken during a fire in the Control Building. According to OFN KC-016 (p14; Rev 18), PORV BB-PCV-455A may spuriously open during a fire in the Auxiliary Building, and its associated Block Valve BB HV-8000 may not close. This can be overcome by locally opening 125 VDC circuit breakers on NK0104 and NK0105. According to OFN KC-016 (p26; Rev 18), the same condition is identified for a fire inside Containment, and according to OFN KC-016 (p28; Rev 18), the same condition is identified for a fire in the Control Building.

A. Generally, there are no immediate action steps in the OFNs; AND OFNs may be implemented concurrently with the EMGs as long as the actions do not interfere with the performance of the EMGs.

B. Generally, there are no immediate action steps in the OFNs; AND OFNs can NOT be implemented once the EMGs have been implemented, except when specifically directed by an EMG.

D. Several OFNs have immediate action steps; AND OFNs can NOT be implemented once the EMGs have been implemented, except when specifically directed by an EMG.

Proposed Answer: A Explanation (Optional):

A. Correct. 1st part correct, 2nd part correct. According to AP 15C-003 (p4 &17; Rev 17),

Steps 4.8.1, 6.4.1 and 6.4.2, operators shall be capable of performing procedure steps identified as immediate actions steps from memory or with the use of memory aids.

202 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet According to AP 15C-003 (p19; Rev 17), Step 6.5.1, all procedure steps not identified as immediate actions steps should be performed by referring directly to the written procedure. According to AP 15C-003 (p18; Rev 17), Step 6.4.5, the recommended assignment of immediate actions is provided in Attachment A, and according to AP 15C-003 (p37; Rev 17), Attachment A identifies three procedures, all of them EMGs that have immediate actions. According to EMG E-0 (p7; Rev 20), a NOTE is provided before Step 1 identifying Steps 1-4 as immediate actions. Similarly, according to EMG FR-S.1 (p4; Rev 15A), a NOTE is provided before Step 1 identifying Steps 1-2 as immediate actions. Similarly, according to EMG C-0 (p4; Rev 18), a NOTE is provided before Step 1 identifying Steps 1-2 as immediate actions. According to EMG ES-0.2 (p4; Rev 18), Step 2 RNO, the operator is directed to use OFN BG-009. According to EMG ES-0.2 (p12; Rev 18), Step 6 RNO, a similar direction exists to OFN BB-005.

According to OFN RP-017 (p16, 20 & 28; Rev 29), Attachments B, C and D have actions that are identified as Immediate Actions Steps. However, they are not to be taken upon entry into the OFN, and only when directed within the body of the procedure. Furthermore, this is the only one of the 40 OFNs that has identified immediate actions. Therefore, generally speaking, there are no immediate actions in the OFNs. According to AP 15C-003 (p15; Rev 17), Step 6.2.3, when operating within the EMGs, the operator may perform OFNs as long as the actions do not interfere with the performance of the EMGs.

B. Incorrect. 1st part correct, 2nd part wrong. This is plausible because there are several OFNs that are directed from steps within an EMG. For instance, according to EMG ES-0.2 (p4; Rev 18), Step 2 RNO, the operator is directed to use OFN BG-009. According to EMG ES-0.2 (p12; Rev 18), Step 6 RNO, a similar direction exists to OFN BB-005.

Because of this, the operator may incorrectly believe that in order for an OFN to be performed while operating within an EMG, is to be specifically directed by the EMG to do so.

C. Incorrect. 1st part wrong, 2nd part correct. This is plausible because the operator may incorrectly believe that in order for an OFN to be performed while operating within an EMG, it must be specifically directed by the EMG.

D. Incorrect. 1st part wrong, 2nd part wrong. This is plausible because according to AP 15C-003 (p22; Rev 17), Step 6.5.9.2, early performance of a step is allowable under certain conditions, and examples of these are given. For instance, starting CCW or an ESW Pump that does not automatically start when it is supposed to, or throttling AFW flow to limit plant cooldown. Based on this, the operator may incorrectly believe that these are immediate actions. However, this allowance does NOT mean that these actions are immediate actions, that MUST be performed from memory or with the use of memory aids; and the operator may incorrectly believe that in order for an OFN to be performed while operating within an EMG, it must be specifically directed by the EMG.

Proposed Question: RO Question # 74 Given the following:

• The plant is at 100% power.

• A fire in the Control Room substantially reduces visibility in the room.

• The Shift Manager decides that the Control Room must be evacuated.

• The operating crew enters the appropriate OFN.

• The reactor is manually tripped.

• The MSIVs are closed.

Which ONE of the following identifies the AFW Pump started by the Reactor Operator, AND the affect that this will have on the plant?

A. Turbine Driven AFW Pump; AND The "B" Steam Generator Level will increase.

B. Turbine Driven AFW Pump; AND The "D" Steam Generator Level will increase.

C. "B" Motor Driven AFW Pump; AND The "B" Steam Generator Level will increase.

D. "B" Motor Driven AFW Pump; AND The "D" Steam Generator Level will increase.

Proposed Answer: D 205 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet Explanation (Optional):

A. Incorrect. 1st part wrong, 2nd part wrong. This is plausible because both the TDAFW Pump and the B MDAFW Pump are started during this procedure. However, according to OFN RP-017 (p13; Rev 29), Steps A10 and A11, the SRO is directed to start the TDAFW Pump and align its discharge to the B Steam Generator.

B. Incorrect. 1st part wrong, 2nd part correct. This is plausible because both the TDAFW Pump and the B MDAFW Pump are started during this procedure. However, according to OFN RP-017 (p13; Rev 29), Steps A10 and A11, the SRO is directed to start the TDAFW Pump and align its discharge to the B Steam Generator. While the D Steam Generator level may raise if only the TDAFW Pump is started, this will NOT be the result of an action taken by the RO.

C. Incorrect. 1st part correct, 2nd part wrong. This is plausible because the operator may incorrectly believe that the B MDAFW Pump start will raise the B Steam Generator Level. According to LO1732427 (p4; Rev 9), the B Train Components are protected during this procedure. According to SY1406100 (p47; Rev 18), the discharge of each MDAFW Pump is normally aligned to two of the four Steam Generators. For instance, B MDAFW Pump is aligned to A and D Steam Generator, while the A MDAFW Pump discharge is aligned to the B and C Steam Generators. While there are cross-connect valves between the pump discharge lines, these valves are normally closed; and NOT opened during the implementation of OFN RP-017. Also, according to OFN RP-017 (p13; Rev 29), Steps A10 and A11, the SRO is directed to start the TDAFW Pump and align its discharge to the B Steam Generator. So the B Steam Generator level will increase during the performance of this procedure; just NOT as a result of the RO starting the B MDAFW Pump.

D. Correct. 1st part correct, 2nd part correct. According to OFN RP-017 (p7; Rev 29),

Step 5, during the evacuation of the Control Room due to a fire event, the SRO is directed to the Auxiliary Shutdown Panel, and directed to perform the actions of Attachment A. According to OFN RP-017 (p8; Rev 29), Step 6, the Reactor Operator is directed to perform the actions of Attachment C. According to OFN RP-017 (p10; Rev 29), Steps A4 and A5, the SRO is directed to align the B MDAFW Pump to the D Steam Generator. According to OFN RP-017 (p23; Rev 29), Step C13, the RO is directed to start the B MDAFW Pump, after the SRO has aligned the pump discharge to the D Steam Generator in accordance with Steps A4 and A5. With the B MDAFW Pump started, and its discharge aligned to the D Steam Generator, the D Steam Generator Level will increase.

Transient trend of coolant temperature toward no-load T-ave Proposed Question: SRO Question # 76 Given the following:

• A loss of off-site power occurred from 100% power.

• All systems responded as designed.

• NO other failures have occurred.

• The crew entered EMG E-0, Reactor Trip or Safety Injection.

• Off-site power became available immediately after the reactor trip.

• The crew is currently performing EMG ES-02, Reactor Trip Response.

Which ONE of the following describes (1) the INITIAL trend of RCS temperature for the first 30 seconds following the trip, and (2) the procedure usage required after transition from EMG ES-02?

RCS Tavg immediately rises due to...

A. Tcold rising, before trending toward no-load Tavg; EMG ES-04, Natural Circulation Cooldown.

B. Tcold rising, before trending toward no-load Tavg; GEN 00-006, Hot Standby to Cold Shutdown.

210 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. Thot rising, before trending toward no-load Tavg; GEN 00-006, Hot Standby to Cold Shutdown.

Proposed Answer: B Explanation (Optional):

A. Incorrect. Plausible because Tcold would rise immediately after the trip. Procedure transition is plausible because it is the normal transition without RCPs. However, RCPs will be restarted in EMG ES-02 because power is available.

B. Correct. Immediately post trip Thot will lower and Tcold will rise as forced circulation stops. Once natural circulation is being established, Tcold will lower and thot will rise as thermal driving head rises for natural circulation to occur.

C. Incorrect. Plausible because Thot eventually will rise to a value consistent with decay heat and natural circulation flow. A delta T must exist between Thot and Tcold to promote natural circulation. RCPs would be restarted in ES-02, so the procedure transition to ES-04 is incorrect.

D. Incorrect. Plausible because Thot eventually will rise to a value consistent with decay heat and natural circulation flow. A delta T must exist between Thot and Tcold to promote natural circulation. Procedure use for cooldown is correct.

(Reference Provided)

A. A RED condition exists on the RCS INTEGRITY Critical Safety Function Status Tree.

Terminate RCS cooldown and initiate an RCS temperature soak in accordance with EMG FR-P1, Response to Imminent Pressurized Thermal Shock Conditions.

B. A RED condition exists on the RCS INTEGRITY Critical Safety Function Status Tree.

Verify RHR flow rate in EMG FR-P1 and then return to EMG E-1 due to the Large Break LOCA in progress.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. An ORANGE condition exists on the RCS INTEGRITY Critical Safety Function Status Tree. Verify RHR flow rate in EMG FR-P1 and then return to EMG E-1 due to the Large Break LOCA in progress.

Proposed Answer: B Explanation (Optional):

A. Incorrect. Plausible because a RED condition exists on the Integrity CSF Status Tree because Tcold are to the left of Limit A. The applicant will have Limit A as a reference but must understand it's use, as no instructions will be given. Since all systems are operating as designed, RHR flow will be greater than 1000 GPM and no soak will be required.

B. Correct.

C. Incorrect. Plausible because the applicant must interpret Limit A and the point of RCS pressure and temperature, and for conditions where RCS pressure is above 325 psig or RHR flow is <1000 GPM, this would be a correct action, as conditions represent a large cooldown in a short period of time.

D. Incorrect. Condition is RED because RCS temperature is to the left of limit A for the pressure provided. Action is to verify RHR flow (Large Break LOCA in progress) and return to procedure and step in effect.

Enter EMG E-1, Loss of Reactor or Secondary Coolant; RCS pressure is low enough that use of EMG FR-H1 is not required, and RCS cooldown will subsequently be performed using EMG ES-12, Transfer to Cold Leg Recirculation.

Proposed Answer: A Explanation (Optional):

A. Correct. Bleed and feed criteria is 26% on 3 of 4 SGs. SG pressure is below RCS pressure, so EMG FR-H1 is required.

B. Incorrect. Bleed and feed is immediately required. The crew may continue attempts to initiate feed, condensate, and AFW, but bleed and feed should not be delayed.

C. Incorrect. Plausible because RCS pressure is below normal SG pressure and close to actual SG pressure. Procedure transition to EMG ES-11 is correct if the applicant misunderstands entry to EMG FR-H1.

D. Incorrect. Same as option C above, but EMG ES-11 would not be entered if all other ECCS was operating correctly. RWST level would not be low enough for a long period of time since the only flow to RCS at 975 psig would be Charging and SI. (lower flow than RHR to reduce RWST level)

Proposed Answer: B Explanation (Optional):

A. Incorrect. Plausible because the applicant may believe that RCPs were tripped due to LOCA. RCPs would NOT have been tripped based on RCS pressure >1400 psig. The applicant must infer that either RCPs were NOT tripped, or that if they were, they would have been restarted in EMG ES-11 prior to this point.

B. Correct. RCS subcooling is currently 61-62°F, and 60°F (adverse containment exists) is required for stopping the first SI Pump.

C. Incorrect. RCS cooldown will continue and SI Pump will be stopped to prevent overfilling the PZR at some point prior to placing RHR in service, as PZR is currently filling and adequate RCS subcooling remains. Plausible because conditions only allow trip of 1 SI Pump based on current subcooling value.

D. Incorrect. RCS cooldown will continue and SI Pump will be stopped to prevent overfilling the PZR at some point. Plausible because if applicant does not realize that RCPs are running, this is logical, since no SI Pumps would be tripped.

Proposed Question: SRO Question # 83 Given the following:

• A reactor trip has occurred due to a loss of offsite power.

• The operating crew is performing actions of EMG ES-04, Natural Circulation

• Cooldown.

• "A" Train RVLIS is out of service.

• The crew has commenced RCS cooldown and depressurization.

• RCS pressure is 1780 psig and trending DOWN.

• RCS Tavg is 448 °F and trending DOWN.

• All SG pressures are at 430 psig and trending DOWN slowly.

• Pressurizer level is 35% and trending UP slowly.

• All CRDM Cooling fans are in service.

• The Shift Manager directs that RCS cooldown rate MUST be performed at approximately 90 °F/hr due to secondary inventory concerns.

Based on current plant conditions, which ONE of the following actions will be required in accordance with EMG ES-04?

A. Remain in EMG ES-04 to continue cooldown and depressurization.

B. Actuate Safety Injection and go to EMG E-0, Reactor Trip or Safety Injection.

C. Transition to EMG ES-06, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS) to continue cooldown.

231 REV SUBMIT

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet D. Transition to EMG ES-05, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS) to continue cooldown.

Proposed Answer: C Explanation (Optional):

A. Incorrect. EMG ES-04 does not permit cooldown at the rate required (>50 °F/hr). (See step 8 of EMG ES-04, RCS cooldown rate is <50 °F/hr; step 13 and the NOTE prior to step 15. The NOTE directs performance of EMG ES-06 or EMG ES-05 if the cooldown rate must be performed at a rate > 50 °F/hr.)

B. Incorrect. RCS pressure is at or near the point where an SI would normally be required, the SI actuation criteria in EMG ES-04 is pressurizer level <6% or RCS subcooling

<30°F, which are not met. With SG pressure and and RCS temperature lowering, the applicant has to determine whether the SG is leading the RCS or the RCS is causing the cooldown.

C. Correct. Since RCS cooldown must be performed at a rate greater than 50 °F/hr, transition to EMG ES-06 is required. (See ES-06, step 8, RCS cooldown rate is <100

°F/hr)

D. Incorrect. Plausible because this would be correct if RVLIS were unavailable, but one train of RVLIS is available (train "B").

Proposed Answer: A Explanation (Optional):

A. Correct.

B. Incorrect. Correct operational concern for a PORV failure while depressurizing in EMG E-3. Incorrect procedure transition. Crew will go to EMG C-31 before any requirement to go to C-32 is met for such reasons as secondary inventory for cooldown is limited.

C. Incorrect. Plausible because a caution prior to the step warns of containment parameters changing if PRT ruptures, but this is not cause for transition to another procedure. PRT could rupture even if PORV closed as required, depending on how long it was open. Procedure transition is correct.

D. Incorrect. Plausible because a caution prior to the step warns of containment parameters changing if PRT ruptures, but this is not cause for transition to another procedure. PRT could rupture even if PORV closed as required, depending on how long it was open. Procedure transition is plausible because the note is placed in EMG E-3 to ensure that an inadvertent transition to EMG E-1 is not made.

C. Plant systems essential for shutdown may be damaged; inspect systems required for safe shutdown in accordance with OFN SG-003, Natural Events, and go to OFN AF-025, Unit Limitations, for the rising condenser pressure.

D. Potential failure of the Cooling Lake Dam is anticipated; maintain reactor power and turbine load stable while placing Essential Service Water in service in accordance with OFN SG-003, Natural Events.

Proposed Answer: B Explanation (Optional):

A. Incorrect. Plausble because the procedure is correct and the procedure has steps that require this action, but in this case, additional damage has caused imminent loss of Circ Water due to loss of the cooling lake.

B. Correct. With level less than 1080 feet, the intake structure will cease to function to provide Circulating Water.

C. Incorrect. Plausible because OFN AF-025 is the normal procedure for reducing load based on rising condenser pressure, and also, OFN SG-003 is required.

D. Incorrect. Plausible because all of the actions are correct except for maintaining load stable. Actions do require maintaining load stable within the procedure, but a plant shutdown is required by the conditions in the stem of the item.

Wolf Creek Generating Station 2009 NRC Examination Written Examination Worksheet C. An immediate shutdown of RCP "D" is required in accordance with OFN BB-005, RCP Malfunctions, Attachment B; RCS boron stratification may occur with loss of forced circulation.

D. A Controlled shutdown of RCP "D" is required in accordance with OFN BB-005, RCP Malfunctions, Attachment C; RCS boron stratification may occur with loss of forced circulation.

Proposed Answer: C Explanation (Optional):

A. Incorrect. Plausible because DNBR is a Mode 1 and 2 basis for operability of RCS loops. Since GEN 00-002 is in progress, the plant is in Mode 4, where the basis becomes decay heat removal and prevention of boron stratification. Plausibility enhanced because the action described is correct.

B. Incorrect. Plausible for same reason as option A. Also, a controlled shutdown would be performed for the RCP if vibration was below 5 mils on the shaft. Frame vibration is less than the limit of 20 mils, and by itself, would require a controlled shutdown if frame vibration was below 5 mils.

C. Correct.

D. Incorrect. Plausibility is same same as second half of option B for controlled shutdown of the RCP. The TS basis, or operational concern, is correct.
