Rev 1, Per Facility Rep, changed answer C to the RPV pressure SL.

Question: 1 Which of the following VIOLATES a Tech Spec Safety Limit (SL)?

A. Two Recirc Pumps are running in slow speed with one Flow Control Valve at MIN ED with reactor power at 27%.

B. Core flow has just been reduced to 70 Mlbm/hr per ONEP; the STA recognizes that MCPR is now reading 1.10.

C. MSIV closure scram with reactor pressure rising to 50 psig above the ATWS/ARI initiation setpoint and all SRVs opened.

D. Plant startup with reactor pressure at 585 psig and both Reactor recirc pumps trip. the STA recognizes that MCPR is now reading 1.15.

Answer: B Explanation:

The Safety limits for GGNS:

2.1.1.1 With the reactor steam dome pressure < 685 psig or core flow < 10% rated core flow Thermal power shall be < 21.8% RTP 2.1.1.2 With the reactor steam dome pressure 685 psig and core flow 10% rated core flow MCPR shall be 1.15 for two recirculation loop operation or 1.15 for single recirculation loop operation.

With core flow at 70 Mlbm/hr it is safe to assume >685 psig reactor pressure and >10% core flow, therefore, MCPR must be > 1.15 and it is 1.10.

B is correct Distracters:

A is wrong, This is a low flow condition that is normal when the plant is performing a startup and shifting the recirc pumps to fast speed. This also does not meet the criteria in Tech Specs 2.1. Plausible due to a reactor recirc low flow condition.

C is wrong, The Reactor pressure safety limit is 1325 psig, 50 psig above the ATWS/ARI setpoint, 1126 psig would be only 1176 psig, below the SL.

D is wrong, First reactor pressure must be >685 psig to make MCPR an issue and MCPR of 1.15 is allowable. If power and flow were at the correct levels.

K/A Match Knowledge of Tech Spec LCOs and Safety Limits are required to answer this question.

Examination Outline Cross Reference Level RO 295003 Partial or Complete Loss of AC Power Tier 1 Group # 1 AK3 Knowledge of the reasons for the following K/A 295003 AK3.07 responses or actions as they apply to partial or complete Rating 3.7 loss of AC power:

Revision 1 AK3.05 Reactor SCRAM Revision Statement:

Rev 1, Per Facility Rep, Reworded answer C for clarity.

Question: 2 The plant is operating at rated thermal power when the normal feeder breaker to Bus 15AA trips due to a ground fault on the bus itself.

Since Bus 15AA cannot be immediately re-energized, the Loss of AC Power ONEP directs operators to manually scram the reactor.

Which of the following describes a reason for scramming the reactor?

A. Anticipates the automatic scram or control rod drifts as a result of a loss of Instrument Air to Containment.

B. It is a conservative action based on the sustainability of plant operation due to the unavailability of Plant Air Compressor A.

C. It is a conservative action to place the plant in a safe shutdown and cooled down condition before a station blackout event might occur.

D. Anticipates the automatic scram that will occur on high drywell pressure as drywell temperature rises due to the loss of two drywell chillers.

Answer: A Explanation:

P53-F001, Instrument Air Supply Header To CTMT, is an air-operated valve that fails closed on loss of power to its solenoid. This Div 1 isolation valves solenoid is powered from 15AA. Therefore, the 15AA loss fails F001 closed, cutting off Instrument Air to that header feeding CTMT. The inboard MSIVs and scram air header are loads on that header. MSIVs will begin to drift closed as air pressure lowers in their control units. An auto-scram will result from the MSIV closure. Control Rods will begin to drift in as scram air pressure lowers to the point that scram valves begin to open. Because this question is asking for just a reason, this single failure mechanism is enough to justify the correct answer. Pre-empting the auto-scram by inserting a manual scram conforms to the Conservative Decision-Making requirements of EN-

OP-115, Conduct of Operations.

Distracters:

B is wrong for the reason already discussed. Also, PAC A is powered from Bus 16AB, not 15AA.

C is wrong. With a loss of one ESF bus the Candidate may associate this with nearing a station black out but not the reason for this action.

D is wrong. This choice is alluding to the two (of 4 total) drywell chillers that are ESF bus powered (the other 2 being BOP bus powered). However, the 2 that are ESF powered are fed from bus 16AB, not from bus 15AA.

K/A Match Knowledge of reason for reactor scram per ONEP procedure.

Revision 2 AA1.03 A.C. electrical distribution Revision Statement:

Rev 1. Per Ops Rep, Changed order of distractors in the description section.

Rev 2, NRC review and comments Deleted part of last sentence and now reads "ESF XFMR 12 is available to energize bus 15AA."

Changed question part of stem to the following, "Circuit breaker 152-1511, FDR FRM ESF XFMR 12 should..."

Deleted "Will" from answer 'A' By changing the last sentence of the stem and the question part answer 'C' is now plausible, the student must know the availability of the circuit breakers without DC control.

Question: 3 Bus 15AA is de-energized.

Battery bus 11DA is de-energized.

ESF XFMR 12 is available to energize bus 15AA.

Circuit breaker 152-1511, FDR FRM ESF XFMR 12 should A. still have automatic trip capability.

B. close and reopen once at the breaker.

C. not be capable of remote or any local operation.

D. open remotely but must be closed manually, at the breaker.

Answer: B Explanation:

Any 4160 breaker cannot be controlled remotely without DC, all operations must be done locally. Any breaker that is already closed when the loss of DC occurs can be opened due to the opening springs are compressed by the closing of the breaker, the opening springs are also compressed when the breaker is closed.

If the breaker is already open then the breaker can be closed and reopened once.

Distracters:

A is wrong; trip coil is DC powered.

C and D are wrong; the breaker will not operate remotely without DC power, but will operate manually at the breaker as described above.

K/A Match Knowledge of Electrical distribution breakers to an ESF bus with a loss of DC control power.

Rev 1, Per Facility Rep, changed wording in answer D Rev 2, NRC Review and comments Deleted one in stem Added "and stabilizes" after constant in answer 'A'.

Question: 4 A main turbine / generator trip has occurred at 45%.

Which of the following describes the effect on reactor pressure?

A. held constant and stabilizes at 935 psig.

B. initial rise then controlled at approximately 935 psig.

C. initial rise then controlled between 926 psig and 1033 psig.

D. held constant at 935 psig then lowers to and stabilizes at approximately 850 psig.

Answer: B Explanation:

At 45% power and a turbine trip occurs a Reactor Scram will also occur. Pressure control will be on the Main Bypass valves but initially Reactor pressure will rise then be controlled at 935psig due to the setpoint on Pressure Set is 935 psig.

Distracters:

A is wrong; Even though the bypass valves will open, reactor pressure will rise before they open to maintain pressure, plausible due to too much power is being produced not to have a pressure rise. If it were a lower power then a scram would not have occurred and pressure would have remained constant.

C is wrong, this assumes the MSIVs have closed due to the pressure band given is the open and close setpoints for SRVs on LO-LO set. Plausible due to setpoints on the LO LO set system

D is wrong; the setpoint can only be manually lowered below 935. Plausible due to the 850 psig number is the lower band number for manual pressure control in the EOPs K/A Match Knowledge of reactor pressure changes during a Turbine trip.

Rev 1, NRC Review and comments Changed "would" to "should" in stem Added "without performing a calculation" to end of stem.

Question: 5 A reactor scram has occurred.

Per Technical Specifications, which of the following should still ensure that sufficient shutdown margin is maintained and that the reactor will remain subcritical under all conditions without performing a calculation?

A. One center core control rod is at position 48.

B. Two peripheral control rods are at position 48.

C. 50% of the control rods are at position 02 or beyond.

D. Groups 1 through 4 of the control rods are at position 04.

Answer: A Explanation:

Per Tech Specs definitions, SDM shall be the amount of reactivity by which the reactor is subcritical or would be subcritical assuming that: (c) All control rods are fully inserted except for the single control rod of highest reactivity worth, which is assumed to be fully withdrawn.

After a scram the crew can determine the reactor shutdown with only one control rod not full in. If more than one is withdrawn then a calculation must be performed.

Distracters:

B is wrong; Even if it is a peripheral rod only one can be withdrawn.

C and D are wrong, see the above explanation. Plausible due to C is used in EP-2A to determine if the reactor can remain shutdown and D is used when determining core density.

Rev. 1, Validation, added switch number for transfer switch.

Rev 2, added Div 2 to answer A Rev 3, NRC Review and comments Changed "it isolates" to "it should isolate" in stem.

Removed "Isolates" from all answers.

Question: 6 The control room has been abandoned due to a fire in panel P864.

Control of the plant has been established at the Remote Shutdown Panels (RSPs).

At local panel P152 (Area 25A, El. 111), operators have placed the following switch in the ON position:

  • Transfer Switch for Lockout Transfer Relay, C61-HSS-M150 When placing this switch in the ON position, it should isolate what equipment from the control room?

A. ALL the Div 2 ESF powered equipment.

B. BOTH Div 1 and 2 ESF powered equipment.

C. ALL the equipment controlled from RSP P150.

D. BOTH equipment controlled from RSPs P150 and P151.

Answer: C Explanation:

Per the site electrical drawings, C61-HSS-M150 energizes lockout relays on H22-P152 which electrically isolate components operated at the H22-P150 (Division 1) Remote Shutdown Panel from the Main Control Room. Other selected Division 1 powered/controlled equipment have isolations provided on

Alternate Shutdown Panels and the Diesel Control Panel. Not all Division 1 equipment is affected by Alternate Shutdown /Remote Shutdown Panels and NO Division 2 equipment is affected.

Distracters:

A is wrong. Plausible because division 1 equipment only is bypassed. The transfer switch does not effect any Division 2 equipment.

B is wrong. Plausible because P150 and P151 are division one and division two equipment only. The transfer switch does not isolate ALL division one and two equipment from control room.

D is wrong. Plausible because P150 is isolated but the P151 is not and is manned at the same time.

Which of the following should auto isolate due to the effects of this condition?

A. Control Rod Drive Pumps B. Reactor Recirculation Pumps C. Reactor Water Cleanup System D. Fuel Pool Cooling and Cleanup System Answer: C Explanation:

With the Temp control valve failing close the CCW temp will rise causing RWCU temp to rise and cause the G33-F004 to auto close at 140 degrees Non regen outlet temp. Therefore, B is the correct answer.

Distracters:

All distracters are plausible due to being loads of the CCW system.

A and B is wrong, but plausible will not auto isolate.

Revision 0 AK2.09 Containment.

Revision Statement:

New Question Question: 8 The plant is operating at rated power when a total loss of instrument air to the Containment occurs.

Which of the following describes the effects on Containment and Drywell cooling water?

Containment Drywell A. Available Available B. Available Unavailable C. Unavailable Available D. Unavailable Unavailable Answer: C Explanation:

A loss of Instrument Air will cause the Containment isolation valves for Plant Chilled water to auto close, PCW supplies the containment coolers. A loss of PCW will cause the Containment Temperature to rise.

This isolation for this system cannot be overridden to allow cooling.

A loss of Instrument Air has no effect on the Drywell Chilled Water System, because a different cooling water system supplies the Drywell coolers. The Drywell Chilled Water System uses MOVs for Ctmt and Drywell isolation valves.

C is Correct Distracters:

A is wrong - but plausible, the candidate must recognize the loss of air only affects air operated valves

not MOVs therefore Cooling to the Containment fan is isolated but Drywell cooling is not.

B is wrong - opposite effects D is wrong - but plausible, the candidate must recognize the loss of air only affects air operated valves not MOVs therefore Cooling to the Containment fan is isolated but Drywell cooling is not K/A Match Knowledge of effects on the containment with a loss of instrument air.

Revision 0 AK3.01 Raising reactor water level.

Revision Statement:

Question: 9 The plant is in Mode 3.

Residual Heat Removal (RHR) B is operating in Shutdown Cooling.

Both Reactor Recirc pumps trip and are unable to be restarted.

The primary reason for the contingency to raise reactor water level for this condition is to:

A. raise circulation through the idle recirc loops.

B. establish a flow path from the core to the feedwater annulus.

C. establish a flow path through the SRVs to the Suppression Pool.

D. provide additional coolant mass to the RPV to absorb decay heat.

Answer: B Explanation:

With no Recirc pumps operating, raising reactor water level to above 82 inches allows natural circulation from the core up through the steam separator to the feedwater annulus for core cooling.

Distracters:

A is wrong but is plausible because a historically common error is to imagine natural circulation to be through recirc loop piping, but it is actually from core to downcomer to core.

D is wrong but is plausible because adding water would provide more heat sink, but that is not why the procedure requires raising level.

C is wrong but is plausible because the procedure does require raising level to the main steam lines to establish flow through the SRVs for Alternate Shutdown Cooling, but this is not warranted since RHR B is already operating in shutdown cooling. Alternate Shutdown Cooling would involve pumping from the suppression pool to the reactor using an ECCS pump and returning to the suppression pool through SRVs to establish a coolant loop.

K/A Match Knowledge of reasons why reactor water level is raised on loss of shutdown cooling.

EK1.03 Safety/relief valve tailpipe temperature/pressure Revision 1 relationships Revision Statement:

NRC Review and comments Added "should have" before "initially" in (1)

Changed "is" to "should be" in (2)

Dec 2017 NRC Exam Q# 12 Question: 12 HANDOUT PROVIDED A transient occurred causing Reactor pressure to rise just high enough to initiate the Lo-Lo Set subsystem of SRVs.

(1) How many SRVs should have initially opened?

(2) What should be the peak SRV tail pipe temperature?

A. (1) One (2) 411°F B. (1) Two (2) 411°F C. (1) One (2) 558°F D. (1) Two (2) 558°F Answer: B

Explanation:

Lo-Lo set system initiates at 1103 psig. Convert 1103 psig to psia by adding 14.7, which is approximately 1118 psia.

Once initiated one SRV lowers its opening setpoint to 1033 psig and another lowers its opening setpoint to 1073, therefore 2 SRVs will initially be open. The other SRVs open at 1113 psig or 1123 psig.

The point of initiation is 1103 psig or 1118 psia reactor pressure; however, tailpipe pressures average about 25% of reactor steam dome pressure for a full valve lift at rated conditions.

1118 X 25% = 279.5 psia.

Saturated temperature for 279.5 psia is 411°F.

B is correct Distracters:

A is wrong. Two SRVs will be open, not one. Plausible if the applicant doesnt remember that when LO-LO-set initiates at 1103 psig the opening setpoint of 2 SRVs lowers to 1033 and 1073, therefore, 2 SRVs will immediately open.

C is wrong. Temperature is for 1118 psia and two SRVs will be open, not one. Plausible if the applicant doesnt remember that when LO-LO-set initiates at 1103 psig the opening setpoint of 2 SRVs lowers to 1033 and 1073, therefore, 2 SRVs will immediately open. Also, if the applicant doesnt recall the process of steam going through a SRV at rated conditions.

D is wrong. Temperature is for 1118 psia. Plausible if the applicant doesnt recall the process of steam going through a SRV at rated conditions.

K/A Match This question requires the applicant to have the knowledge of Safety/relief valve tailpipe temperature/pressure Relationships and the operational implications of the indication.

Revision 1 EK3.04 SBLC injection Revision Statement:

NRC Review and comments Changed question (1) to: "At what suppression pool temperature should the CRS call for SBLC injection?"

Question: 13 An ATWS has occurred Reactor power is 2.5%

(1) At what suppression pool temperature should the CRS call for SBLC injection?

(2) Which of the following describes the reason for SBLC injection?

A. (1) Before 110 F (2) Maintain Containment temperature and pressure limits B. (1) Before 110 F (2) Prevent Large scale power instabilities leading to core damage C. (1) After 110 F (2) Maintain Containment temperature and pressure limits D. (1) After 110 F (2) Prevent Large scale power instabilities leading to core damage Answer: A Explanation:

Per 02-S-01-40, EP Technical Bases, Attachment V page 37 of 58 states the following:

If reactor power is at or below 5%, thermal-hydraulic instabilities are not of significant concern since the core boiling boundary will be relatively high and the core void content will be relatively low. Some

oscillations may still occur, but large-scale instabilities leading to core damage are not expected. Boron injection then need not be injected unless primary containment integrity is jeopardized.

A is correct Distracters:

B is wrong. At <5% the bases states large-scale instabilities leading to core damage are not expected.

C is wrong. EP-3 states that before suppression pool 110 inject with boron not after, plausible due to the EPs uses before and after setpoints, the student must know its before setpoint.

D is wrong. At <5% the bases states large-scale instabilities leading to core damage are not expected.

AND EP-3 states that before suppression pool 110 inject with boron not after, plausible due to the EPs uses before and after setpoints, the student must know its before setpoint.

K/A Match This question requires the applicant to have the knowledge of the reason for injecting SBLC during an ATWS.

Knowledge of the operational implications of the Rating 3.8 following concepts as they apply to HIGH CONTAINMENT TEMPERATURE (MARK III CONTAINMENT ONLY) : Revision 0 EK1.03 Containment integrity: Mark-III Revision Statement:

NRC Review and comments UNSAT NEW QUESTION Question: 14 Per EP-3, Containment Control, BEFORE Containment temperature reaches

°F, the containment design temperature, is required.

A. (1) 185 (2) Entry into EP-2, Reactor Scram B. (1) 210 (2) Entry into EP-2, Reactor Scram C. (1) 210 (2) Emergency RPV Depressurization D. (1) 185 (2) Emergency RPV Depressurization Answer: A Explanation:

Per 02-S-01-40, EP Technical Bases, Attachment VI Per EP-3 Bases, page 16 of 37, this is the containment design temperaturei.e., where containment damage or challenge to equipment operability may occur.

If containment temperature continues to increase, a reactor scram is performed through concurrent entry of EP-2. The scram is prescribed for the following reasons:

The scram reduces the rate of energy production and thus the heat input to the containment.

If containment temperature continues to increase, emergency RPV depressurization will be required.

The reactor should be scrammed before the emergency depressurization is performed. While a high

drywell pressure scram signal may also be present, this may not be the case in all scenarios; conditions requiring entry of EP-3 do not necessarily require entry of EP-2.

The scram is prescribed indirectly, through entry of EP-2, because:

EP-2 coordinates control of RPV water level and pressure following the scram.

EP-2 branches to EP-2A, ATWS RPV Control, to provide appropriate guidance if all rods are not inserted by the scram.

An override in the Pressure branch EP-2 allows rapid depressurization through the main turbine bypass valves in anticipation of a possible emergency depressurization.

If containment temperature cannot be restored and maintained below 185°F, the containment design temperature, emergency RPV depressurization is required. This strategy limits the release of energy into the containment, thus minimizing further containment heatup, and ensures that the RPV is depressurized before temperature rises high enough to damage the containment or challenge equipment operability limits. Consistent with the definition of cannot be restored and maintained in Section 3.0, a decision that containment temperature cannot be restored and maintained below 185°F can be made may be made before, when, or after temperature actually reaches this value.

A is correct Distracters:

B is wrong, the temperature is 185 not 210. Plausible because per 02-S-01-40, EP Technical Bases, 210 is the design for the suppression pool not the containment C is wrong. the temperature is 185 not 210. Plausible because per 02-S-01-40, EP Technical Bases, 210 is the design for the suppression pool not the containment and an emergency depressurization is required if containment temperature cant be restored and maintained below 185.

D is wrong. an emergency depressurization is required if containment temperature cant be restored and maintained below 185.

K/A Match This question requires the applicant to have the knowledge of the implications of high containment temperature and the effects.

NRC May 2017 (Q14)

Question: 15 What is the reason for operating all drywell cooling when Drywell Temperature exceeds the EP-3 entry condition?

A. To maintain Drywell temperature less than the ADS qualification temperature where a Reactor scram is required B. To maintain Drywell temperature less than the Drywell design temperature limit where an Emergency Depressurization is required C. To prevent exceeding the Drywell temperature where the ADS/SRVs are declared INOP D. To reduce and maintain Drywell temperature less than the Drywell temperature Tech Spec LCO.

Answer: D Explanation:

The Drywell temp. EP-3 entry condition is 135°F, 02-S-01-40, EP Technical Bases, states As long as drywell temperature remains below 135°F, the higher of the drywell temperature LCO and the maximum normal operating drywell temp., no further operator action need be taken in the DW temp. branch.

D is correct Distracters:

A is wrong - same as B, by maxing drywell cooling you should maintain below the ADS qualification temperature (355°F), an ED is required if this setpoint cannot be maintained. Not just a reactor scram.

B is wrong - by starting all available drywell cooling could be to prevent exceeding the design temperature limit (330°F), only a scram is required not an ED.

C is wrong - the ADS qualification temp is 355°F not 135°F K/A Match This question requires the applicant to have the knowledge of the reason for increasing cooling.

A. 10.5 ft.

B. 14.5 ft.

C. 14.25 ft.

D. 17.5 ft.

Answer: A Explanation:

The suppression pool level to Emergency Depress is 10.5 ft., 02-S-01-40, EP Technical Bases, SRVs may be opened only if suppression pool water level is above 10.5 ft., the bottom of the suppression pool water level indication range. If suppression pool water level were low offscale, the actual water level could be below the top of the SRV discharge devices. Opening the SRVs with the discharge devices exposed would pass steam directly into the containment airspace, bypassing the suppression pool.

A is correct Distracters:

B is wrong - The specified suppression pool water level of 14.5 ft. corresponds to an elevation 2 ft.

above the top of the horizontal vents.

C is wrong - At GGNS, all suppression pool temperature elements are located at or above 14.25 ft.

Rev 1, NRC Review and comments Changed is to should and added approximately to stem.

Question: 18 An ATWS has occurred.

Standby Liquid Control has been initiated.

Initial SLC storage tank level was 4800 gallons.

The first SLC pump should be secured per EP-2A in approximately

__________ minutes?

A. 24 minutes B. 34 minutes C. 68 minutes D. 116.5 minutes Answer: B Explanation:

The SLC pumps are designed for 41.2 gpm and when SLC is initiated both pumps are started, therefore 82.4 gpm is being injected into the vessel. When SLC storage tank reaches 2000 gallons then one pump is to be shutdown per EP-2A. So 4800 gal - 2000 gal = 2800 gals. 2800 gals / 82.4 gpm = 33.98 minutes.

B is correct

Distracters:

A is wrong - Plausible due to if the student thinks that 2000 gal. must be pumped instead of 2000 gal indicated.

C is wrong - Plausible due to the student must remember that both pumps will be started, this is the time for one pump running.

D is wrong - Plausible due to this would be the time for the entire tank to be pumped using only one pump.

Revision Statement:

Per NRC review (10 free view) SAT Question: 22 A LOCA has caused drywell pressure to reach 2.8 psig.

Drywell temperature is 211°F A complete loss of offsite power has occurred, including the Port Gibson line.

All DGs have re-powered the ESF buses.

NO Operator actions have been performed.

Which of the following identifies the method of heat removal from the drywell under the current plant conditions?

A. Heat removal from the drywell is only by ambient losses without air circulation.

B. Drywell Coolers and Drywell Chilled Water System 'B' are operating on SSW 'B'.

C. 'A' Drywell Cooler fans are circulating air but the coolers are without cooling water flow.

D. 'B' Drywell Cooler fans are circulating air but the coolers are without cooling water flow.

Answer: A Explanation:

Drywell pressure caused an LSS LOCA Shed and Sequence. The Drywell Coolers are powered from 15B42 and 16B42, which are shed on a LOCA and not automatically re-energized. Operator action is required to restore power to the Drywell Coolers. 15B42 and 16B42 are shed and re-energized automatically on a loss of power, however the LOCA signal will override the loss of power sequence.

Additionally, the Drywell Chilled Water supply and return valves will be automatically isolated due to the

Drywell Pressure.

A is correct Distracters:

B is wrong - Plausible, procedures does not allow Drywell Chilled Water to be restored by reopening isolation valves without complete system startup when Drywell temperature is > 200°F, SSW B is aligned for LOCA cooling which is not aligned to the DW chilled water system and B Chilled water system is powered from Div 2 16AB which is locked out on a LOCA by LSS.

Question: 23 An inadvertent Containment isolation signal has occurred and will not reset.

The CRS directs to restore the Auxiliary Building per the Automatic Isolations ONEP.

Five minutes after the actions are complete:

(1) temperature should remain constant due to ventilation cooling water (2) .

A. (1) Containment (2) automatically aligning to SSW.

B. (1) Containment (2) being able to be bypassed and restored.

C. (1) Drywell (2) being able to be bypassed and restored.

D. (1) Drywell (2) automatically aligning to SSW.

Answer: C Explanation:

After an isolation signal the ONEP allows to restore certain systems that can bypass the isolation signal:

Instrument Air Drywell Chilled Water Therefore, Drywell temperature will remain the same due to a brief interruption with cooling water.

The Containment coolers are cooled by Plant Chilled water system that receives an isolation signal and no ability to bypass the isolation, therefore no cooling water will be supplied to the coolers and Containment temperature will rise.

C is correct Distracters:

A. Overflowing the Drywell weir wall.

B. ECCS initiation and RPV injection from suppression pool.

C. Maximum amount of water received from the upper pools.

D. Level has reached the point of transmitters being submerged.

Answer: A Explanation:

The design of the Suppression Pool Makeup system is without considering any other inputs, an

inadvertent SPMU dump will raise Suppression Pool level to 23.8' if pool level was initially at its normal level of 18.5' or raise level approximately 5.3 ft. With suppression pool level at 19.5 plus the 5.3 dumped is 24.8. the Weir wall to the Drywell stands at 24.3 therefore the level stabilizing is from overflowing of the weir wall.

A is correct Distracters:

B is wrong - but plausible, the max indication on the Suppression Pool level indicator is 25.5 wide range.

C is wrong - but plausible, the design of the Suppression Pool Makeup system is without considering any other inputs, an inadvertent SPMU dump will raise Suppression Pool level to 23.8' if pool level was initially at its normal level of 18.5' or raise level approximately 5.3 ft. With suppression pool level at 19.5 plus the 5.3 dumped is 24.8. the Weir wall to the Drywell stands at 24.3.

D is wrong - Plausible, the upper pools dump will fill the suppression pool to 5 below the top of the weir wall with suppression pool level at the high level alarm setpoint.

K/A Match This question requires the applicant to interpret the indications of a high suppression pool level.

Question: 25 A steam line within the Auxiliary Building Main Steam Tunnel has a leak.

Current MST temperature is 105°F.

MST room temp is rising at 5° F / min (1) When should automatic actions initiate?

After the MST reaches the MAX SAFE temperature, RCIC room temperature begins to rise:

(2) If the break cannot be isolated, what is the MINIMUM RCIC room temperature that would procedurally require the CRS to direct an Emergency Depressurization?

A. (1) 16 minutes (2) 212°F B. (1) 16 minutes (2) 225° C. (1) 29 minutes (2) 212°F D. (1) 29 minutes (2) 225°F Answer: A Explanation:

Per 02-S-01-40, EP Technical Bases, EP-4 Table SC-1, Automatic actions will occur at 185°F in the MST, a Group 1 isolation will occur. At 5°F/ min it will take 16 minutes for the steam tunnel to rise 80°F.

For EP-4 to call for a Emergency Depressurization it requires an unisolable leak and two Max safe values of the same type (i.e. temp). Therefore per Table SC-1 the Max safe for the MST is 250°F and RCIC is 212°F A is correct Distracters:

B is wrong - Plausible, The given temperature is for the RHR rooms not the RCIC room C is wrong - Plausible, 29 minutes is the time to reach the Max Safe value for the MST of 250°F. 185°F is the setpoint for a Group 1 isolation and EP-4 entry.

D is wrong - Plausible, 29 minutes is the time to reach the Max Safe value for the MST of 250°F. 185°F is the setpoint for a Group 1 isolation and EP-4 entry. The given temperature is for the RHR rooms not the RCIC room K/A Match This question requires the applicant to diagnose and recognize trends of a steam leak using reference material.

What action(s) should be procedurally performed FIRST?

A. Raise reactor water level to +82.

B. Raise reactor water level to between +101 and +129.

C. Start LPCS and inject to maintain 55 psig in the reactor.

D. Place RHR Pump B and SSW pump B in Shutdown Cooling.

Answer: D Explanation:

Per 05-1-02-III-1, Inadequate Decay Heat Removal ONEP, IF inservice loop of Shutdown Cooling has been lost, THEN PLACE redundant loop in Shutdown Cooling OR ADHRS in service per SOI 04-1 E12-2.

Just a loss of the SSW system causes a loss of cooling water flow to the RHR heat exchangers, therefore a loss of cooling.

D is correct Distracters:

A is wrong - Plausible, Per 05-1-02-III-1, Inadequate Decay Heat Removal ONEP, IF forced circulation (no Reactor Recirculation pumps running) has been lost, THEN RAISE Reactor water level to 615" actual (this is 82" above instrument zero). This would be the action of both Recirc pumps were lost.

B is wrong - Plausible, Per 05-1-02-III-1, Inadequate Decay Heat Removal ONEP, IF adequate cooling CANNOT be maintained OR restarted within the estimated time to 200°F, THEN PERFORM the following:

SLOWLY RAISE RPV water level using any available injection systems to between

+101 inches AND +129 inches to establish flow through open SRVs back to Suppression Pool.

C is wrong - Plausible, Per 05-1-02-III-1, Inadequate Decay Heat Removal ONEP, this step is performed after the above step in B is performed:

IF RPV pressure does NOT stabilize above 55 psig, THEN START additional RHR pump(s) AND OPEN its associated Injection Valve (E12-F042A,B,C).

K3.02 Primary containment isolation system/nuclear Revision 1 steam supply shut-off: Plant-Specific Revision Statement:

Rev 1, NRC Review and comments Changed will to should in stem Question: 35 The plant is operating at rated power.

The incoming feeder breaker to the 16AB bus trips and the Div 2 DG restores 16AB power.

The MSIV/ DR VLV TRIP INIT red alarm is sealed-in.

Which of the following should cause all MSIVs to close?

A. 1/2 Scram on A side B. Main Steam Tunnel Temp B fail high C. Main Steam Tunnel delta temp A fail high D. C71-S003A, MG SET A OUTPUT BREAKER trip Answer: D Explanation:

MSIV solenoids are powered from RPS bus power. Both MSIV solenoids losing power is required for the MSIVs to close.

A loss of 16AB will cause a loss of logic power to the group 1 MSIVs isolation system. This in turn causes a 1/2 isolation on Div 2 (B) side and loss of power to the Div 2 solenoids for the MSIVs. This is given with the receiving of the MSIV/ DR VLV TRIP INIT red alarm To close the MSIVs power must be removed from the Div 1 solenoids.

D is correct. C71-S003A is an EPA breaker but with this breaker tripping will cause all power to be

removed from the RPS A bus and power to the A MSIV solenoids. Now both solenoids are without power and a full MSIV closure will occur.

Distracters:

A is wrong - This action will only cause a 1/2 scram not a MSIV closure, power must be totally removed for the RPS bus to remove power to the B solenoids for the MSIVs. RPS power is only removed from the Scram logic. Plausible due to scram logic and MSIVs solenoids are powered from the RPS bus.

B is wrong - With a B temperature in the steam tunnel failing high would cause a Group 1 valve logic to initiate, however this would initiate a Div 2 isolation signal which the Div 2 solenoid is already de-energized from the loss of logic power.

C is wrong - Main Steam tunnel delta Temp no longer provides a Group 1 isolation signal.

Rev 1, NRC Review and comments (U)

Changed question and answers to determine which status lights are OFF Question: 36 HANDOUT PROVIDED The plant is currently in a refueling outage and operators are pulling fuses on a clearance for a Reactor Protection System (RPS) logic modification.

  • Currently fuse 1C71F27B is removed.
  • The Non-licensed operator has just removed fuse 1C71F14C.

Using E1173-019 determine which of the RPS System SCRAM SOL VLV status lights on P680 are OFF.

A. All lights are OFF B. 1A through 4A and 1B OFF only C. 1A through 4A only D. 1B only Answer: B Explanation:

Ref E1173-019; pulling fuse F27B only de-energizes white indicating light 1B, not the K14B or K14F relays. Pulling fuse F14C, de-energizes K14C and K14G which gives a half scram in channel 'C' which is a Division I channel and all Div 1 lights will be off 1A through 4A B is correct.

Distracters:

A is wrong - this answer assumes a full scram but by pulling the K14C will cause a half scram only and pulling F27B only deenergizes the light 1B, C is wrong - only indicates all div 1 lights not the one div 2 light only D is wrong - pulling fuse F27B only de-energizes white indicating light, not the K14B or K14F relays.

Pulling fuse F14C, de-energizes K14C and K14G which gives a half scram in channel 'C' which is a Division I channel.

K/A Match This question requires the applicant to have the ability to determine individual system relay status with given conditions with the RPS system.

Clarified question in the stem, the RCIC system Group 4 isolation signal cannot be reset from the RSP, all other auto actions can be reset or bypassed from outside the control room. Added to the stem "...for continued operation from the remote shutdown panel." Changed answer C to an actual isolation signal that the student must recognize as such.

Question: 41 Events have occurred and the Control Room has been evacuated.

RCIC is initiated and controls are taken from the Remote Shutdown Panel.

Plant operator has been dispatched to the RCIC room.

Which of the following should cause RCIC to be unavailable for continued operation from the Remote Shutdown Panel?

A. Overspeed trip B. RPV level 8 is reached C. RCIC Exhaust Diaphragm pressure 15 psig D. Auto suction swap to Suppression Pool Answer: C Explanation:

If RCIC is operating from the remote Shutdown Panel and a Group 4 isolation is received then RCIC will no longer be available for level control due to the Group 4 cant be reset from the remote shutdown panel.

The correct answer of RCIC Exhaust Diaphragm pressure of 15 psig is above the setpoint for a Group 4 isolation signal. The setpoint is 10 psig. The student has to determine that the Group 4 isolation signal was exceeded and that a Group 4 isolation will prevent operation of RCIC from the Remote Shutdown Panel.

C is correct.

Revision 1 A1.01 ADS valve tail pipe temperatures Revision Statement:

Rev 1 - Validation, made a 1 / 2 question Question: 42 A loss of all RPV level indication has occurred during a LOCA.

The CRS has entered EP-5 and directed injection into the RPV.

The CRS has directed you to monitor for RPV flooding.

(1) Which of the following describes the tail pipe temperature indication for RPV flooding?

And (2) Which valves should be monitored?

A. (1) Rising (2) ADS valves only B. (1) Lowering (2) ADS valves only C. (1) Rising (2) LO-LO Set SRVs only D. (1) Lowering (2) LO-LO Set SRVs only Answer: B Explanation:

Per EP-5 Flooded RPV Indications for SRV tail pipe is Lowering SRV tailpipe temperatures

Flooded RPV Indications NOTE: Some combination of the following conditions should be observed as water fills the steam lines and flows through SRVs. No single indication can be relied on in all events.

  • Rising RPV pressure
  • Lowering SRV tailpipe temperatures
  • If injecting from the suppression pool, SP level lowers as the RPV and steam lines are flooded, then stabilizes when the steam lines are full.
  • If injecting from outside the CTMT, SP level rising.

When EP-5 was entered one of the first directions is to Emergency Depressurize the RPV. That direction is to open 8 ADS valves.

No Is SP level above 10.5 ft

?

2 Yes Open 8 ADS/SRVs.

A OK to exceed 100°F/hr cooldown.

A OK to defeat isolations and restore air. Att 7 3

Open 8 ADS/SRVs RPV depressurization can most easily and rapidly be performed by opening SRVs. Those associated with the ADS function are used first, consistent with automatic system functions. The ADS SRVs are generally considered the most reliable and are arranged to provide uniform distribution of the heat load around the suppression pool. If one or more ADS valves cannot be opened, other SRVs are opened until the total number of open SRVs equals the number of SRVs dedicated to ADS function.

B is correct Distracters:

A is wrong - Even though water will be exiting the SRV the Water temperature is lower that the steam temp therefore, tailpipe temp will lower not rise, the EP-5 says to open 8 ADS valves not LO-LO set valves.

C is wrong - Even though water will be exiting the SRV the Water temperature is lower that the steam temp therefore, tailpipe temp will lower not rise.

D is wrong - EP-5 says to open 8 ADS valves not LO-LO set valves.

K/A Match This question requires the applicant to have the ability to monitor tail pipe temperatures during ADS valve operation.

D. An estimated feedwater flow signal replaces the failure transmitter with no change in control.

Answer: C Explanation:

Hard-failures of feedwater flow signals are responded to by immediately de-selecting and disabling three-element control.

Distracters:

A is wrong - Plausible because if all four level channels hard fail the level control stations will automatically swap to MANUAL.

B is wrong - Plausible if the upscale feed flow signal is sensed and used as a good input to the level control system. High feed flow the system would attempt to reduce feed flow to anticipate a rise in level due to feed flow steam flow mismatch.

D is wrong - Plausible because an estimated feedwater flow can replace the normal total feedwater flow

signal and three-element control can be re-selected and returned to service.

Rev 1, NRC Review and comments Changed answers to a 2X2, Added "Without any operator action." to the stem. Due to loss of power ONEP has the bus restored as an immediate action.

Question: 47 Division 1 Diesel Generator is currently in MAINT MODE.

The voltage to ALL ESF busses drops to 3290 volts.

The voltage transient duration is 10 seconds and then voltage returns to normal.

All other plant parameters are normal.

Without any operator actions:

(1) Which one of the following states the condition of the ESF busses after this voltage transient?

And (2) What should be the status of the ECCS systems?

A. (1) 16AB and 17AC are energized by their Diesel Generators (2) Only Division 2 and 3 ECCS systems are available B. (1) 16AB and 17AC are energized by their Diesel Generators (2) All ECCS systems are available C. (1) 16AB is energized by its Diesel Generator only (2) Only Division 2 and 3 ECCS systems are available D. (1) 17AC is energized by its Diesel Generator only (2) All ECCS systems are available

Answer: C Explanation:

This is a 79% BUV which after 9 seconds will cause a Div 1 & 2 Shed causing those buses to be transferred to the EDG; however, the 88% Div 3 BUV will not shed its bus unless the condition persists for 5 minutes. With Div 1 D/G in MAINT the D/G for 15AA will not start and 15AA will remain deenergized.

Therefore Division 2 and 3 ECCS are the only ones available.

C is correct Distracters:

A is wrong, the 17 bus will not energize from its D/G B is wrong, Div. 3 D/G did not get a start signal so 17AC is still energized through normal power feed and Div 1 ECCS is not available.

D is wrong, Div. 3 D/G did not get a start signal so 17AC is still energized through normal power feed and 16AB is powered from its DG K/A Match This question requires the applicant to have the knowledge to use the given information and determine the status of the ECCS safety systems.

NRC Review and comments (U)

Changed question.

Question: 51 If Instrument Air header pressure drops to a__________ psig setpoint on Control Room panel 1H13-P870, the Air Bleed Off Station will vent the remaining air in the Instrument Air header to the Auxiliary Building atmosphere.

A. 110 psig B. 90 psig C. 60 psig D. 30 psig Answer: D Explanation:

If Instrument Air header pressure drops to ~30 psig, Air Bleed Off Station pilot valve F523 opens to vent the air from the air operator on PV-F531, causing it to fail open This vents the remaining air in the Instrument Air lines to the Auxiliary Building atmosphere. This ensures that any radioactive contamination, from the Containment or Drywell, that may have entered the depressurized and potentially degraded Instrument Air System lines, will be treated by the Standby Gas Treatment System rather than leak to the environment via a leak in the Instrument Air header somewhere outside the Auxiliary Building (Secondary Containment).

D is correct Distracters:

A is wrong - Normal Control Room indication, plausible due to the air compressors will auto start on receiver pressure, the normal receiver pressure is 125 to 135 psig B is wrong - This would be approximately the pressure at which the standby air compressor would auto start but the auto start comes from the receivers not the header. Also the low limit on the Control Room

rounds C is wrong - This is the local air pressure at which a type of air operated valves will auto close to preserve closing capability.

K/A Match This question requires the applicant to have ability to monitor the Instrument Air pressure in the control room by knowing location of indication and normal value and actions of low header pressure.

(1) closing E22-F001 and then opening E22-F015 (2) manually opening E22-F001 then close E22-F015 Answer: A Explanation:

Per ARI P601-16A-C5 (SUPP POOL LVL HI), the suction swap occurs by opening E22-F015 and then

closing E22-F001. Although it is possible to manually realign the suctions at any point, a caution in the ARI reads "Restore normal suppression pool level before realigning HPCS suction to the CST."

Placing the switch momentarily in the OPEN position, will open the valve provided:

  • it is in the fully closed position and,
  • the HPCS Pump Suction from Suppression Pool Valve is NOT fully open.

F015 must be closed first A is correct Distracters:

Question: 54 Given the following CRD system components:

C11-F003, CRD DRIVE WTR PRESS CONT VLV C11-F002, CRD FLOW CONT VLV Which of the following describes how CRD Drive Water D/P is maintained during reactor pressurization?

A. F003 is adjusted manually ONLY to maintain D/P and flow until rated pressure is achieved in the RPV.

B. F003 automatically adjusts position to maintain D/P while the F002 automatically positions to maintain flow during pressurization.

C. F003 is manually set to provide the required D/P initially then the automatic positioning of the F002 will maintain D/P during pressurization.

D. F003 automatically adjusts position to maintain system flow which in turn will maintain the required D/P until pressurization is complete.

Answer: C Explanation:

During a reactor startup and pressurization the drive water D/P is set at 250 psid. As reactor pressure rises CRD flow begins to drop due to higher pressure in the RPV, the CRD FCV F002 will open to maintain set flowrate of 60 gpm. When the F002 opens to provide more flow the D/P will rise back to the set value. Therefore, with the flow control valve in automatic, set at 60 gpm, and the pressure control valve set at 250 psid, as reactor pressure increases, the flow control valve opens to provide more flow and maintain the appropriate drive water p.

C is correct

Distracters:

A is wrong - Only one adjustment is needed to maintain D/P B is wrong - F003 is a manual MOV and does not operate in automatic D is wrong - F003 is a manual MOV and does not operate in automatic K/A Match This question requires the applicant to have the knowledge of the design features of the CRD system to control D/P.

Question: 64 A Control Rod Drop can occur when a control rod becomes stuck and uncoupled for the CRD mechanism.

(1) When would a Control Rod Drop accident be more of an impact on the Reactor?

(2) What action should be performed by the crew to recouple the Control Rod?

A. (1) 5% power, Startup (2) Individual control rod scram.

B. (1) 100% Rod Line, end of core life (2) Normal insertion C. (1) 100% Rod Line, end of core life (2) Individual control rod scram D. (1) 5% power, Startup (2) Normal insertion Answer: D Explanation:

The given indications are a control rod that has become uncoupled from the CRD mech. This could be the setup for a control rod drop accident. Per Tech Specs Bases 3.3.2.1, Compliance with the BPWS, and therefore OPERABILITY of the RPC, is required in MODES 1 and 2 with THERMAL POWER s 10%

RTP. When THERMAL POWER is > 18% RTP, there is no possible control rod configuration that results in a control rod worth that could exceed the 280 cal/gm fuel damage limit during a CRDA (Ref. 3). In

MODES 3 and 4, all control rods are required to be inserted in the core. In MODE 5, since only a single control rod can be withdrawn from a core cell containing fuel assemblies, adequate SDM ensures that the consequences of a CRDA are acceptable, since the reactor will be subcritical.

D is correct Distracters:

A is wrong. Per CRD SOI precaution and limitation, 3.13 Scramming control rods Should only be done as part of testing OR in emergency situations.

B is wrong. When THERMAL POWER is > 18% RTP, there is no possible control rod configuration that results in a control rod worth that could exceed the 280 cal/gm fuel damage limit during a CRD drop.

C is wrong. Per CRD SOI precaution and limitation, 3.13 Scramming control rods Should only be done as part of testing OR in emergency situations. When THERMAL POWER is > 18% RTP, there is no possible control rod configuration that results in a control rod worth that could exceed the 280 cal/gm fuel damage limit during a CRD drop.

Per EN-OP-115-08, Annunciator Response, section 9, The announcement of transient alarms during Abnormal/ONEP and EOP is not required. In such cases, the operators are expected to announce those alarms that are of significance to the implementation of the applicable Abnormal/ONEP and EOP.

The Drywell Pressure Hi alarm should be immediately reported to the CRS. He is required to enter EP-3 and Re-enter EP-2. Also this alarm could be indicative of a LOCA in the drywell.

B is correct Distracters:

A is wrong - This alarm will be in due to pressure control on the SRVs from the MSIV closure.

C is wrong - This alarms indicates an auto transfer to slow speed and is an action that should have already happened due to turbine trip.

D is wrong - This alarm will be in due to a scram signal and will not reset until the scram is reset.

K/A Match This question requires the applicant to have the ability to recognize, interpret and prioritize control room alarms during a transient.

Revision 3 AA2.02 Reactor power / pressure / and level.

Revision Statement:

Rev 1 - Validation comment add MSIVs have closed instead of the student determine that they closed Rev 2 - Validation comment Added No other EP Entry conditions have been exceeded.

Rev 3, NRC Review and comments Changed stem to state "A grid disturbance causes a loss of offsite power" this will cause all MSIVs to close and a loss of all Condensate / Feedwater.

The addition of No other EP entry conditions is to have them determine that Suppression Pool Temp has not exceeded 110 degrees that would cause a different Level band.

B(2) should now be plausible, the applicant must determine that MSIVs have closed and this is not possible.

Question: 76 The plant is operating at rated conditions.

MSIVs have closed.

Current conditions:

  • Rx power is 11%
  • Rx pressure is maintaining between 926 and 1073
  • Rx water level is +10 and lowering
  • No other EP entry conditions have been exceeded With the given conditions, (1) What should be the CRSs direction for RPV level control?

(2) What should be the CRSs direction for RPV pressure band?

A. (1) Lower level to -70 inches Wide Range Rev. 4

(2) Lower Pressure band 450 to 600 psig B. (1) Lower level to -70 inches Wide Range (2) Maintain pressure band 800 to 1060 psig C. (1) Lower level to -167 inches Fuel Zone Range or <5% power (2) Lower Pressure band 450 to 600 psig D. (1) Lower level to -167 inches Fuel Zone Range or <5% power (2) Maintain pressure band 800 to 1060 psig Answer: A Explanation:

First determine that MSIVs have closed An ATWS occurs due to power at 11% after MSIVs are closed and with water level at 10 inches.

SRVs are open due to the pressure being maintained is 926 to 1073 psig which is the opening and closing setpoints for the lo-lo set SRVs.

The CRS should enter EP-2 then to EP-2A and lower level to -70 Wide Range. Pressure control should be manually controlled at a band of 450 to 600 psig due to loss of feedwater and lowering band will allow Condensate to feed and control level.

Level should be lowered to -70 inches per EP-2A, the lowering to TAF is a Step 8 terminate action and that criteria is not met yet. Step L5 has to have suppression pool temperature >110.

A is correct.

Distracters:

B is wrong, the pressure band is incorrect. Pressure must be lowered to ensure the Condensate system is able to feed.

C is wrong, Level should be lowered to -70 inches per EP-2A, the lowering to TAF is a Step 8 terminate action and that criteria is not met yet. Step L5 has to have suppression pool temperature >110.

D is wrong, Level should be lowered to -70 inches per EP-2A, the lowering to TAF is a Step 8 terminate action and that criteria is not met yet. Step L5 has to have suppression pool temperature >110. Also, the pressure band is incorrect. Pressure must be lowered to ensure the Condensate system is able to feed.

K/A Match The SRO candidate must be able to interpret the given information with a loss of power and decide on the correct actions to take.

Rev 1 - Validation comment, add RCIC has tripped on overspeed to ensure SRO knows level is being controlled by a high volume system.

Rev 2, NRC Review and comments Changed answer B to Restarting.

Question: 77 A complete loss of Feedwater occurred at rated power.

Both Reactor Feed Pumps are tripped due to a spurious high water level signal that remains sealed in.

RCIC has tripped on overspeed.

The CRS directs level control using HPCS.

Reactor water level is +20 inches Narrow Range.

Which of the following Scram ONEP steps should the CRS direct the RO to skip?

A. Inserting IRMs.

B. Restarting RWCU.

C. Resetting RPS Scram logic.

D. Restarting Reactor Recirc Pumps.

Answer: C Explanation:

The level band when HPCS is used for level control is -30 to +50 per 02-S-01-43 and EP-2. Scram Rev. 4

ONEP 05-1-02-I-1 step 3.7 directs resetting the RPS scram only if level is stable, to ensure subsequent scrams are not received. Since level is expected to go below 11.4 for the current level band, resetting the scram is not appropriate.

C is correct.

Distracters:

Candidate must assume that RPV level lowered to less than level 2 (-41.6). At rated conditions and a total loss of Feedwater level will lower to approximately -60 to -80 All distracters are plausible because they are Scram ONEP subsequent actions, but they are wrong because they are advantageous and are not affected by current conditions.

A is wrong, Step 3.6.2 of the SCRAM ONEP states to insert IRMs, there is no reason not to insert the IRMs at this time.

B is wrong, Step 3.10 states in the CAUTION . IF no Reactor Recirculation pumps are running, THEN section 3.11 AND 3.12 Should be performed concurrently without delay to prolong the onset of thermal stratification. Step 3.10 states IF Reactor Water Cleanup System (RWCU) has tripped, THEN RESTART RWCU per Attachment I after Reactor water level AND pressure have stabilized.

D is wrong, See 3.10 CAUTION from above. Step 3.11 states, IF no Reactor Recirculation pumps are running, THEN PERFORM the following without delay. Step 3.11.4 START Both Reactor Recirculation pumps, IF available, in slow speed per Attachment II.

K/A Match The candidate must be able to interpret the given information on reactor water level and conditions and decide on the correct actions to take.

Rev. 1, Per Ops Rep, Changed correct answer to match current operations philosophy.

Rev 2, NRC Review and comments Changed "will to "should" in stem May 2017 NRC Exam Q 79 Question: 78 HANDOUT PROVIDED An ATWS has occurred.

Current conditions are:

  • Reactor power is 40%
  • Reactor pressure is 1045 psig and steady
  • Two SRVs are currently open
  • Suppression pool level is at the Tech Spec low level limit
  • Suppression pool temperature is 150°F and rising.
  • RHR A and RHR B systems have just been placed in Suppression Pool Cooling Which of the following describes the next action the CRS should direct?

A. Emergency Depressurize the Reactor when HCTL is exceeded B. Lower pressure band to prevent entering unsafe zone of HCTL C. Immediately Emergency Depressurize the Reactor when exceeding HCTL is predicted.

Rev. 4

D. Anticipate an Emergency Depressurization and fully open the Main Turbine Bypass valves Answer: B Explanation:

With the plant maintaining current conditions, reactor power exceeds the capacity of the bypass valves therefore SRVs will continue to be opened to maintain pressure. With SRVs open Suppression pool temp will rise.

In the pressure branch of EP-2A, it states If SP temp cannot be maintained in the Safe Zone of the HCTL THEN, maintain RPV pressure in the Safe Zone of the HCTL.

SRO must know EP steps without reference.

B is correct.

Distracters:

All other distractors are plausible, they all are different paths that could be taken if the student forgets the step in the EOPs and that HCTL can be exceeded if it can be restored to the safe zone.

A is wrong - Emergency Depress is required only if RPV pressure cannot be restored and maintained in the Safe Zone of the HCTL.

C is wrong: Emergency Depress is required only if RPV pressure cannot be restored and maintained in the Safe Zone of the HCTL. Since the RHR systems have just been started in Suppression Pool cooling the SRO should wait and determine if the limit can be restored.

D is wrong - Reactor power is too high, the Bypass valves are already fully open and procedures do not allow to anticipate an ED while in EP-2A ATWS.

K/A Match The candidate must be able to interpret the effects of the given information with reactor power and reactor pressure to determine the next action.

Revision 2 Revision Statement:

Rev 1, Facility Rep. grammar on stem question, added is to and changed answers to fit the format.

Rev 2, Added clarity to answer B by adding during a DBA.

Question: 79 One bases for the Tech Spec ACTION to immediately suspend RCIC flow testing based on high Suppression Pool temperature is to.

A. Preclude having to enter EP-3, Containment Control.

B. Ensure the Containment temperature limit is not exceeded during a DBA.

C. Prevent RCIC turbine exhaust check valve chatter that can damage RCIC piping.

D. Prevent elevated RCIC turbine lube oil temperature that could damage RCIC turbine.

Answer: B Explanation:

In the stem, RCIC flow testing implies power is above 1%. TS 3.6.2.1 Action C.1 requires immediately suspending testing that adds heat to the Supp Pool when Supp Pool average temperature exceeds 105°F. The implication in the stem is Supp Pool temperature has just exceeded 105°F.

Suppression pool average temperature is allowed to be > 95°F with THERMAL POWER > 1% RTP when testing that adds heat to the suppression pool is being performed. However, if temperature is > 105"F, the testing must be immediately suspended to preserve the pool's heat absorption capability. With the testing suspended, Condition A is entered and the Required Actions and associated Completion Times are applicable.

TS bases 3.6.2.1 states the Supp Pool temperature limit was developed to address technical concerns that include limiting containment average air temperature to < 185°F during the DBA.

B is correct.

Rev. 4

Distracters:

A is wrong - is plausible because entry into an Emergency Procedure is undesirable and implies elevated risk and challenge to plant safety, but it is wrong because TS 3.6.2.1 Action C that requires suspending testing that is adding heat to the Supp Pool at 105°F, so the Supp Pool Temperature EP-3 entry condition of 95°F would have already been met, so EP-3 entry cannot be avoided.

C is wrong - is plausible because exhaust check valve operation could theoretically be affected mechanistically by Supp Pool parameters, but it is wrong because 04-1-01-E51-1 step 3.2 states this is a concern for operation of RCIC at speeds below 2000 rpm and because RCIC operability is not a concern in the DBA analysis and is not mentioned in the bases for TS 3.6.2.1.

D is wrong - is plausible because it describes undesired effects of elevated Supp Pool temperature on RCIC. It is each wrong because 04-1-01-E51-1 step 3.3 states RCIC suction temperature is limited to 140°F for non-emergency operation to prevent bearing/turbine seals overheating, and during emergencies, EP caution 4 states RCIC equipment damage could occur if Supp Pool temperature exceeds 225°F, well above the 105°F condition implied in the stem and because RCIC operability is not a concern in the DBA analysis and is not mentioned in the bases for TS 3.6.2.1.

K/A Match The candidate must have the knowledge of the bases in Technical Specifications for limiting conditions for operations on Suppression Pool Temp.

Rev 1 Per NRC review (10 free view) changed wording in stem of question, added procedurally required. Added more explanation about entering alternate level control leg of EOPs.

Question: 80 The plant has experienced a LOCA All High pressure injection systems are not available.

Reactor Water level has reached the lowest indication for Wide Range.

Which of the following describes the procedurally required RPV pressure control being directed by the CRS?

A. LO-LO Set SRVs.

B. Emergency Depressurization.

C. Pressure band 450 - 600 psig using SRVs.

D. Pressure band 800 - 1060 psig using Main Bypass Valves.

Answer: B Explanation:

In the stem, when all high pressure feed is lost the CRS/SRO should enter the alternate control leg of the EOPs. There, other systems are started in an attempt to restore level. If RPV water level continues to lower as Reactor water level reaching the lowest indication is -160 Wide Range. Per EP-2 When level drops to -160 in. Emergency Depressurization is Required. The SRO must recognize that the reactor must be depressurized.

B is correct.

Rev. 4

Distracters:

A is wrong - is plausible because during a LOCA it is permissible to use LO-LO Set system to control pressure within band. However, the given information requires an ED.

C is wrong - is plausible because this is a band that is used to feed with Condensate. However, with no high pressure feed bases states not to lower the pressure band with nothing to feed.

D is wrong - With level indicated at -160 Wide Range the MSIVs would have closed at -150.3, therefore, Main Bypass Valves are unavailable.

K/A Match The candidate must have the knowledge of how to control reactor pressure with a low reactor water level.

Per 05-1-02-II-1, Shutdown from the Remote Shutdown panel ONEP, the following actions are time critical action for a fire in the control room.

IF a Main Control Room fire is in progress, the Reactor Operator dispatched to perform Attachment XX Should complete the actions to manually start Div I Diesel Generator (IF NOT auto started) within 8 minutes of reactor being scrammed AND Should complete actions to Close the Div I Diesel Generator output breaker within 12 minutes of reactor being scrammed.

IF a Main Control Room fire is in progress, the CRS AND FSS (Remote Shutdown Panel) to perform Attachment XXI will complete the actions to Defeat LSS AND open the 15 Bus breakers within 8 minutes of reactor being scrammed.

IF a Main Control Room fire is in progress, the CRS AND FSS at the Remote Shutdown Panel to perform Attachment XXI will complete the actions to open the SRVs to depressurize the Reactor within 12 minutes.

IF a Main Control Room fire is in progress, the CRS AND FSS at the Remote Shutdown Panel to perform Attachment XXI will complete the actions to depressurize AND inject RHR A to the reactor within a maximum of 14.3 minutes.

Per step 3.1.3 actions prior to leaving the control room does not include RCIC.

C is correct.

Distracters:

A is wrong - Depressurize the RPV is also required.

B is wrong - Initiating RCIC is not required prior to leaving the Control Room during a Fire but it is required if evacuating for any other reasons.

D is wrong - This action is from 05-S-01-FSG-002, Alternate RCIC Suction Source, that is to be used during an extended loss of AC power, not from the remote shutdown panel.

Revision Statement:

Question: 88 The plant is at 90% power following a sequence exchange.

The following occurs:

  • ADS / SRV LEAK. P601-18A-G-2, and SRV/ADS VLV OPEN/DISCH LINE PRESS HI, P601-19A-A5 annunciators are received
  • Generator megawatt output has lowered by approximately 75 MWe
  • SRV B21-F041D has a red indication on P601 handswitch
  • Suppression Pool average water temperature is currently 98°F and rising
  • Suppression Pool Water Level is 18.71ft. and rising.
  • Handswitches on P601 and P631 for SRV B21-F041D are taken to the CLOSE position
  • I&C has been notified to pull associated fuses per ARI.

What is the next required action to correct, control, or mitigate the impacts of this event on the plant?

A. Lower Reactor power B. Place the Reactor Mode Switch to SHUTDOWN C. Place one loop of RHR in Suppression Pool Cooling D. Place both loops of RHR in Suppression Pool Cooling Answer: D Rev. 4

Explanation:

With the given information the student can determine that a stuck open SRV exsist.

ONEP 05-1-02-V-21, Reactor Pressure Control Malfunctions is entered and section 3.3 refers you to the ARIs to perform actions to get the SRV closed, which are in progress from the given information.

The next action should be enter EP-3 (>95°F Suppression Pool Temp.) and start all available Suppression Pool cooling (not needed for adequate core cooling). The SRO should direct both loop of suppression pool cooling to be started per EP-3. Before SP temp reaches 110°F the SRO will enter EP-2 which requires a Mode Switch to SHUTDOWN. This is based on Tech Spec 3.6.2.1 and bases. If the actions of the ARI do not close the SRV then ONEP directs a plant shutdown.

D is correct.

Distracters:

A is incorrect - The ONEP does provide actions to lower reactor power but not in this case only if pressure control system is malfunctioning.

B is incorrect - IF the actions of the ARI fail and the SRO determines that Supp Pool Temp will reach 110°F then the ONEP directs a mode switch to shutdown.

C is incorrect - When the EPs are entered due to supp pool temp the direction is to start all available cooling systems, not just one.

K/A Match The candidate must have the ability to predict the impact of a stuck open SRV and determine the correct procedure and action to mitigate the event.

Question: 89 The plant is at rated thermal power when the following alarms are received:

  • RX LVL 40/32 HI/LO The plant has the following conditions:
  • Reactor power - 82%
  • Core Flow - 85 mlbm/hr
  • RFPT B speed - 5850 rpm
  • Reactor water level is slowly lowering (1) Given the alarms and conditions, what event has occurred?

(2) The CRS should transition to _________________ procedure that contains the actions to mitigate these conditions.

A. (1) Complete Reactor Recirc Flow Control Valve Runback (2) ONEP 05-1-02-V-7, Feedwater System Malfunctions.

B. (1) Complete Reactor Recirc Flow Control Valve Runback (2) ARI 04-1-02-1H13-P680-2A-A2, RFPT A TRIP.

D. (1) Partial Reactor Recirc Flow Control Valve Runback (2) ONEP 05-1-02-V-7, Feedwater System Malfunctions Answer: D Rev. 4

Explanation:

With the indications given the Recirc FCVs did not completely runback due to high core flow and power, Reactor power is too high for one Feedpump to handle. ONEP 05-1-02-V-7, Feedwater System Malfunctions contains the action to ENSURE Reactor Recirculation System Flow Control Valve runback occurs (62 Mlbm/hr). The term Ensure means if it did not occur then perform actions to make it happen.

D is correct.

Distracters:

A is incorrect - If a complete runback would have occurred then core flow would be approximately 62 Mlbm/hr.

B is incorrect - If a complete runback would have occurred then core flow would be approximately 62 Mlbm/hr. ARI directs to refer to the ONEP C is incorrect - ARI directs to refer to the ONEP K/A Match The candidate uses the given alarms and parameters to verify system actions are in concurrence with the alarm response manual and transition to another procedure to mitigate the event.

Question: 90 HANDOUT PROVIDED From rated power a normal plant shutdown has begun with all three Emergency Diesel Generators inoperable and unavailable.

The following occurs:

  • Tornado results in a loss of all offsite power
  • RCIC automatically initiates and restores reactor water level to a band of

-30 to +50

  • 45 minutes after the initial power loss, offsite power is restored to buses 15AA and 17AC Bus 16AB remains de-energized.

What is the emergency classification for this event?

A. Unusual Event B. Alert C. Site Area Emergency D. General Emergency Answer: C Explanation:

Per EAL SS1: Stem conditions are consistent with the SS1 declaration criteria: Loss of all offsite power Rev. 4

and loss of all onsite AC power (i.e., no EDGs available) to Div 1, 2, & 3 ESF buses (i.e., 15AA, 16AB, 17AC) for >15 minutes.

D is correct.

Distracters:

Because RCIC restored level and because power was restored to at least one ESF bus (actual to two buses) within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, EAL SG1 does not apply, making D plausible, but wrong.

The plausibility of distracters A and B are based on the SRO Applicant wrongly applying EALs SU1 or SA1 for the loss of power that occurred. SU1 is wrong because it considers a loss of power to only the Div 1 and Div 2 buses. SA1 is wrong. Although it considers a loss of power to the point of a Station Blackout (or one failure short of a Blackout), to remain at the Alert level, the condition must last no more than 15 minutes.

K/A Match The candidate must have the knowledge of the emergency action level thresholds and classifications.

Rev 2, NRC Review and comments Changed CRS in 4th line to CRD Added required action to question part of the stem Question: 91 The Plant has experienced an ATWS.

The CRS calls for the Nominal Band for Reactor Water level and pressure.

Current RPV water level is -50 inches and slowly lowering.

Attachments are installed for control rod insertion and CRD has been maximized for pressure.

The RO inserting control rods reports control rod movement has stopped and CRD system flow rate is pegged full upscale with C11-F002A, CRD FLO CONT VLV indicating green only indication.

Which of the following describes the required action by the CRS?

A. Maximize CRD for Flow B. Restore the Aux Building C. Call for Attachment 24, Vent CRD Overpiston Volumes, to be installed Rev. 4

D. Call for Attachment 22, Place Individual Scram Test Switches in TEST, to be installed Answer: B Explanation:

With the given indications an Aux building/Containment isolation occurred at -41.6 inches and therefore causing instrument air to isolate to the containment. The failure of the Flow control valve is loss of air, the FCV will fail as is but drift close due to instrument air leaks. As the FCV closes control rod motion will stop. To mitigate this event the CRS must call for Restore the Aux Building per EP-2A and restore Air to the Aux building and Containment.

B is correct.

Distracters:

A is wrong - This action is performed during an ATWS prior to installation of Attachments 18, 19 and 20.

This should cause control rods to drift in due to high cooling water pressure. This action will have no effect on the FCV due to the loss of Air.

C is wrong - Attachment 24 should be used when control rods cant be moved due to hydraulic block, but not in this situation, this also requires an entry into the Containment, not advised during an ATWS.

D is wrong - Attachment 24 should be used when control rods cant be moved due to failure to de-energize scram solenoids, but not in this situation, this also requires an entry into the Containment, not advised during an ATWS K/A Match The candidate must be able to predict the impacts low system flow and using procedures mitigate the event.

ECCS OR SRVs (non-ATWS) -30 inches to +50 inches should be used due to RCIC is INOP and ECCS (HPCS) will be used to control level.

To restore normal level control the ARI should be used First, with normal level indicated, the CRS can have the relay for low condenser hotwell level be removed and the Condensate System be restored.

B is correct.

Distracters:

A is wrong - the level band given is only used during normal situations, in this case ECCS system is being used for level control, therefore the expanded band should be used.

C is wrong - the level band given is only used during normal situations, in this case ECCS system is being used for level control, therefore the expanded band should be used and the actions to remove the relay is in the ARI not the ONEP.

NEW QUESTION.

Question: 95 Per EN-OP-115-14, Reactivity Management, which of the following would require dedicated SRO oversight other than the CRS with no concurrent duties?

A. Reducing power using Recirc flow to 85% for surveillance test.

B. Performing a sequence exchange after lowering power to 65%.

C. Performing 06-OP-C11-M-0001, Control Rod Operability Surveillance.

D. Raising power using Recirc flow from 80% to rated conditions at a ramp rate given by the RE.

Answer: B Explanation:

Using Attachement 1 of EN-OP-115-14, Reactivity Management, the SRO must determine the risk level of the manipulation. Sequence exchange or power maneuver where power is lowered to <70% is considered a High Risk Reactivity Manipulation.

The Required Minimum Controls for Reactivity Risk Level for a High Risk Reactivity call for Reactivity SRO Oversight (Dedicated SRO, other than the CRS, with no concurrent duties)

B is correct.

Rev 1, NRC Review and comments Remove reference Dec 2017 NRC Exam Q97 Question: 97 A small packing leak was discovered on P11-F130, REFUEL WTR XFER PMP SUCT FM SUPP POOL.

Maintenance has tightened the packing on the valve per a Work Order.

A maintenance leak check was performed and the leak was stopped.

What post-maintenance testing is required to be performed by Operations before the Work Order may be closed?

A. Functional stroke of valve IAW P11 SOI B. Timed stroke of valve IAW P11 valve operability surveillance test C. Functional stroke of valve with local visual observation IAW P11 SOI D. Local leak rate test (LLRT) to verify Suppression Pool leakage within allowable limits IAW Engineering LLRT procedure Answer: B Explanation:

The candidate is expected to recognize that this is a safety-related primary containment isolation valve in the BOP condensate and refueling water transfer system.

Maintenance activities to tighten the packing of this valve represent a potential to affect the valve stroke time. A timed valve stroke per the appropriate surveillance procedure is required to demonstrate the valve meets the requirements of Tech Specs and the IST program.

Rev. 4

B is correct.

Distracters:

A is wrong, but plausible. Although this will demonstrate functionality of the valve post-maintenance, Tech Specs and the IST program impose valve stroke time requirements that must be determined by a timed valve stroke performed IAW the applicable surveillance procedure.

C is wrong, but plausible. Although this will demonstrate functionality of the valve post-maintenance, Tech Specs and the IST program impose valve stroke time requirements that must be determined by a timed valve stroke performed IAW the applicable surveillance procedure and local observation is not required.

D is wrong, but plausible. Tightening of the valve packing does not present the potential to affect how leak-tight the valve is. While the original packing leak did present a concern for challenging limits on allowable Suppression Pool leakage into the Secondary Containment, a Maintenance leak check PMT is adequate to show that the leakage is stopped. A full LLRT of the penetration is not required.

K/A Match The applicant must recognize the correct post maintenance test requirements Technical

Question: 98 A Site Area Emergency is in progress.

A control room RO needs to be sent into the plant to perform a task.

Per 10-S-01-17, against what dose limits does the CRS (without additional concurrence) compare the current dose to determine if there is sufficient exposure margin?

A. 10CFR100 Reactor Site Criteria B. GGNS Administrative Dose Limits C. Authorized Emergency Exposure Dose Limits D. 10CFR20 Standards for Protection Against Radiation Answer: D Explanation:

See 10-S-01-17, sections 6.1.2 and 6.1.3. By definition, the administrative dose limits are automatically suspended and replaced by the 10CFR20 Federal dose limits at the declaration of an Alert emergency or higher.

See 10-S-01-17, sections 6.2.1 and 6.7.1.b. The latter section clearly states that if the limit is likely to be exceeded (i.e., after determining if sufficient exposure margin exists), then obtain an Exposure Extension Authorization per section 6.1. Clearly then, the SRO compares the ROs current dose against the 10CFR20 Federal limits.

D is correct.

Distracters:

A is wrong - CFR 100 deals with Reactor Site Criteria.

Rev. 4

B is wrong - the administrative dose limits are automatically suspended and replaced by the 10CFR20 Federal dose limits at the declaration of an Alert emergency or higher.

C is wrong - Section 6.1 deals with the limits suggested by this answer, these limits are for protecting equipment and life.

K/A 2.4.29 Rating 4.4 Revision 1 Revision Statement:

Rev 1, Per Ops Rep, added alarm FP LEVEL TROUBLE, this alarm is the basis of the EP-4 entry condition.

Question: 99 HANDOUT PROVIDED The plant is in Day 5 of a Refueling Outage.

The Reactor cavity pool is drained and preps are being made to remove the Drywell Head.

New fuel is being transferred to the Containment Pool.

The Reactor Cavity gate seal fails.

P680-4A2-A6, FP LEVEL TROUBLE alarm is received Fuel Pool Cooling and Cleanup pumps have tripped on low Drain Tank level.

RO reports ARM D21-K622, Aux Bldg Fuel Hdlg Area, indication is rising.

(1) What is the current emergency classification?

(2) Which procedure(s) should be entered to mitigate this event?

A. (1) Unusual Event.

(2) High Radiation During Fuel Handling ONEP only B. (1) Alert.

(2) EP-4 and High Radiation During Fuel Handling ONEP C. (1) Unusual Event.

(2) EP-4 and High Radiation During Fuel Handling ONEP Rev. 4

D. (1) Alert.

(2) High Radiation During Fuel Handling ONEP only Answer: C Explanation:

Per EAL flow charts Modes 4 through De-Fuel UNUSUAL EVENT - AU2 UNPLANNED water level drop in reactor refueling pathways as indicated by water level drop in Upper Ctmt Pools, Aux Bldg Fuel Pools or the Fuel Transfer Canal, personnel observation or indication on area camera.

AND VALID Area Radiation Monitor reading rises on any of the following:

Ctmt 209 Airlock --------------------------------- (1D21K630)

Ctmt Fuel Hdlg Area ---------------------------- (1D21K626)

Aux Bldg Fuel Hdlg Area ---------------------- (1D21K622)

The given information is lowering pool levels and a rising radiation on D21K622, therefore an Unusual Event is required.

When the Fuel Pool Cooling and Cleanup pump tripped on low drain tank level meant that the scuppers are uncovered due to the lowering level the scuppers are located below level of 207.49 ft. which is an entry condition for EP-4.

The CRS should enter EP-4 and also enter High Rad During Fuel Handling ONEP.

C is correct Distracters:

A is wrong - EP-4 has met an entry condition and is required to be entered. Plausible due to the candidate must have the knowledge of relative levels of the Spent Fuel Pools vs. EP-4 entry condition.

B is wrong - Only an UE is declared, the upgrade to an ALERT requires level to reach the fuel which with the given information will not happen due to the fuel is recessed within the pool and level will not reach them and a high rad alarm which has not come in yet.

D is wrong - EP-4 has met an entry condition and is required to be entered. Plausible due to the candidate must have the knowledge of relative levels of the Spent Fuel Pools vs. EP-4 entry condition.

Only an UE is declared, the upgrade to an ALERT requires level to reach the fuel which with the given information will not happen due to the fuel is recessed within the pool and level will not reach them and a high rad alarm which has not come in yet.

K/A Match Candidate must have knowledge of the Emergency Play to correctly classify this event.
