1. Given the following plant conditions:
  • Reactor Power is 85%, steady state, all systems in NSA.
  • RCS pressure is 1045 psig and LOWERING.
  • RCS temperature is 545 of.
  • Pressurizer level is 78% and RISING.

The Control Room Team is performing E-O, "Reactor Trip or Safety Injection" when the following plant conditions develop:

  • RCS pressure is 1200 psig and slowly RISING.
  • RCS temperature is 545 of.
  • Pressurizer level is 32% and LOWERING.

Which ONE of the following is the cause of these changing plant conditions?

A. An open PORV has reseated.

B. A faulted steam generator has boiled dry.

C. The size of the RCS leak has increased.

J. The turbine failed to trip and the MSIVs were closed.

Answer: A Explanation/Justification:

A. Correct. The candidate must have knowledge of the interrelations between a PRZR vapor space accident and sensors and detectors. During situations where a steam vent path is established from the PRZR vapor space and where subcooling is not indicated, PRZR level may not be a true indication of RCS inventory. The candidate must sort through the various indications provided by sensors and detectors and analyze these indications to determine a PORV has lifted and is no longer lifting (vapor space accident). They must understand the interrelations of these indications to rule out the other choices.

B. Incorrect. PRZR level would act in the opposite way if the faulted S/G boiled dry.

C. Incorrect. RCS pressure would drop if the RCS leak size increased.

D. Incorrect. If the turbine failed to trip, PRZR level would act in the opposite direction due to initial plant cooldown until the MSIVs closed.

2. Given the following plant conditions:
  • The Unit was operating at Full Power with all systems in NSA.
  • A LOCA occurred and the Control Room Team transitioned to E-1, "Loss of Reactor or Secondary Coolant".

The following plant conditions exist:

oRCS pressure is 550 psig and slowly DROPPING.

o Core Exit Thermocouple Temperatures are 472 OF and slowly DROPPING.

oRCS loop cold leg temperatures are 442 OF and slowly DROPPING.

o S/G pressures are 375 psig and slowly DROPPING.

oRCS 11T is indicating UPSCALE.

o RCP's are NOT running.

Based on these conditions, which ONE of the following identifies the source(s) of SI flow providing core cooling, AND what is the status of natural circulation?

A. High Head SI flow ONLY; Natural Circulation is occurring.

B. High Head AND Low Head SI flow; Natural Circulation is NOT occurring.

C. High Head SI Flow AND SI Accumulators; Natural Circulation is occurring.

J. High Head SI flow AND SI Accumulators; Natural Circulation is NOT occurring.

Answer: C Explanation/Justification:

A. Incorrect. Partially correct that High Head SI flow is a source of cooling, however, SI Accumulators are also a source. Correct natural circulation conclusion (refer to correct answer explanation)

B. Incorrect. Incorrect that natural circulation is not occurring. Low Head SI flow is NOT a source of SI flow (refer to correct answer explanation)

C. Correct. With RCS pressure at 550 psig, the High Head SI pumps & SI Accumulators (Begin to inject when RCS pressure drops < 600 psig) will be supplying SI flow for core cooling. The shutoff head for the Low Head SI pumps is about 1i'8 psig so therefore will not be providing flow.

Natural circulation is occurring because of the conditions specified on Attachment A-1. 7 are met. Both ES-1.1 & 1.2 reference Attachment A-1. 7 for verification of natural circulation flow in the LOCA series procedures making this question operational relevant.

D. Incorrect. Correct sources of SI flow. Incorrect natural circulation conclusion (refer to correct answer explanation)

3. Given the following plant conditions:
  • The Unit is at Full Power with all systems in NSA.
  • The thermal barrier heat exchanger for the "21A" RCP develops a 75 gpm tube leak.
  • All systems function as designed.

Which ONE of the following describes the effect this leak will have on the Primary Component Cooling Water System (CCP)?

The "21A" RCP thermal barrier _ _ __

A. outlet isolation valve automatically closes on high pressure.

B. inlet & outlet isolation valves automatically close on high flow.

C. outlet isolation valve automatically closes on high flow with the inlet isolated by a check valve.

D. inlet isolation valve automatically closes on high flow with the outlet isolated by a check valve.

Answer: C Explanation/Justification:

A. Incorrect. Correct that "A" RCP outlet thermal barrier isolation valve isolates, however, the isolation is on flow versus pressure. Plausible because RCS pressure is higher than CCP.

B. Incorrect. There is only an outlet thermal barrier isolation valve that auto isolates.

~. Correct. The candidate must understand the system design features and system interrelationship between CCP and a thermal barrier leak. In accordance with OM Chapter 15/AOP at 58 gpm (significant tube leak - loss of Reactor Coolant Flow from system into CCP), the thermal barrier outlet isolation valve associated with the effected RCP will auto close.

D. Incorrect. Opposite of correct configuration. Plausible if the candidate does not know the system interrelations.

4. Given the following plant conditions:
  • The Unit is shutdown and cooled down to 235 of where Tavg is STABLE.
  • All systems are aligned for these plant conditions.
  • "A" RCP is running.
  • The running charging pump experiences an overcurrent trip.
  • The Control Room Team enters AOP 2.7.1, "Loss of Charging or Letdown".

Which ONE of the following actions will be REQUIRED within the next hour?

A. Isolate letdown and establish excess letdown.

B. Initiate boration to restore shutdown margin within limits.

C. Perform seal injection surveillance to ensure seal injection flow meets TS 3.5.5, "Seal Injection Flow" requirements.

D. Restore a charging pump to functional status to meet LRM 3.1.2, "Boration Flow Paths Operating" requirements.

Answer: 0 Explanation/Justification:

A. Incorrect. AOP 2.7.1 does direct letdown to be isolated so therefore this is a correct action. It is also plausible that excess letdown is placed in service although not procedurally required. There is also no 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> time limit for this action to occur.

1. Incorrect. This is not an action directed by AOP 2.7.1, however, TS 3.1.1 does have a less than 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> action statement to initiate boration to restore SDM within limits. Although plausible this is not an action that is necessitated based on the plant conditions provided since SDM should not have changed nor have been effected since Tavg is stable.

C. Incorrect. AOP 2.7.1 does direct action to check RCP seal injection flow. The TS 3.5.5 required action is a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> action statement. Also this TS applies in Mode 1,2, & 3 and is not applicable in Mode 4.

D. Correct. The candidate must know that the plant is currently in Mode 4. The RO candidate is also required to know TS/LRM actions which are one hour or less from memory. LRM 3.1.2 is applicable in Mode 4 and requires the flowpath from tile refueling water storage tank via one charging pump to the RCS to be functional. Condition C allows one hour to restore this flowpath from the RWST to functional status. The candidate must also have knowledge of AOP-2.7.1 actions in order to analyze and rule out the alternate choicl9S. With RCS Temperature < 240 F (enable temperature) only one charging pump is functional/operable and an alternate charging pump will need to be made functional.

5. Given the following plant conditions:
  • The plant is in Mode 5 with the Pressurizer (PRZR) solid.
  • The following indications occur:

o A1-2G. "INCORE INST ROOM/CNMT SUMP LEVEL HIGHNALVE NOT RESET' annunciated.

o 2DAS*Ll220. "Reactor CNMT Sump Level" reads 5.1" and is RISING.

o 2DAS*Ll222, "Reactor CNMT Sump Level" reads 5.1" and is RISING.

o 2RCS-Ll-462. "PRZR Cold Calib Level" is 70% and is rapidly DROPPING.

Based on these indications. which ONE of the following procedures will be entered AND what action will be taken?

(AOP 2.6.5. "Shutdown LOCA")

(AOP 2.10.1. "Loss of Residual Heat Removal Capability")

A. Enter AOP 2.6.5 and actuate Safety Injection.

B. Enter AOP 2.6.5 and start all charging pumps.

C. Enter AOP 2.10.1 and isolate letdown/known drain paths.

D. Enter AOP 2.10.1 and check RCS Inventory and then go to AOP 2.6.5.

\nswer: C Explanation/Justification:

A. Incorrect. Incorrect procedure since the plant is in Mode 5 versus Mode 4. Incorrect plausible action that is checked but not directed by this procedure.

B. Incorrect. Incorrect procedure since the plant is in Mode 5 versus Mode 4. Correct action directed by this procedure.

C. Correct. The candidate must recognize from the indications provided that a leak into containment from the RHR or RCS is occurring. They must also have knowledge based on these indications of the actions taken in accordance with the applicable procedure. Both AOP 2.6.5 and 2.10.1 have entry conditions for uncontrollable PRZR level drop. AOP 2.10.1 is applicable in Mode 5 when not in a reduced inventory mid loop condition and would be entered. One of the actions taken is to isolate letdown and known drain paths to attempt stopping the loss of inventory. AOP 2.6.5 is applicable in Mode 3 & 4 ONLY. The RO is required to know AOP entry conditions and understand overall mitigative strategies or sequence of events which occur.

D. Incorrect. Correct procedure entry with a plausible correct action to check inventory, however, since the plant is in Mode 5 a transition to AOP 2.6.5 is not applicable and therefore will not occur making this choice incorrect.

6. Given the following plant conditions and sequence of events:
  • The Plant is operating at 50% power.
  • Pressurizer (PRZR) 2A & 2B Backup Heaters are in the ON position.
  • The Pressurizer (PRZR) Master pressure controller output failed AS IS.
  • A load rejection (step load decrease of 10%) occurs.
  • No operator action is taken.

Based on these plant conditions, what will be the impact of the load rejection on PRZR Spray Valve [2RCS*PCV455A] position AND the two groups of energized PRZR Backup Heaters [2A

& 2B]?

2RCS*PCV455A willlNITIALL Y _ (1) _ .

Energized PRZR heaters will _ (2) _ .

A. (1) open (2) de-energize B. (1) further open (2) remain energized C. (1) remain as is (2) de-energize D. (1) remain as is 2 remain ener ized Answer: D Explanation/Justification:

A. Incorrect. Incorrect spray valve response. Plausible if candidate does not recognize the impac.t of the Master pressure Controller failure. PRZR heaters will remain energized. Plausible if the candidate believes PRZR level drops to 14% which cuts off PRZR heaters by interlock.

B. Incorrect. Incorrect spray valve response. Without the malfunction it is correct that the valve would further open. Correct PRZR Backup Heater response.

C. Incorrect. Correct spray valve response. PRZR heaters will remain energized. Plausible because PRZR heaters are designed to turn off with increasing PRZR pressure.

D. Correct. A load rejection results in an increase in RCS temperature. (Plant will not trip due to reactor power level) The Tavg increase will cause an expansion of water into the PRZR (Insurge) compressing the vapor space which in turn will increase PRZR pressure. On increasing PRZR pressure, the Master Pressurizer Control System is designed to open the Spray Valves to lower PRZR pressure back to NOP (2235 psig).

However, since the Master Pressure Controller has failed as is, it will not respond to the chan!~ing system parameters and therefore will not reposition Spray Valves open. Backup PRZR heaters 2A & 2B will remain energized because they are energized on and the master pressure controller has failed at a setpoin! which will not cause them to turn off regardless of what happens to PRZR pressure following the transient. A 10% drop in power will result in a 3.S% PRZR level increase which is insufficient to turn all PRZR heaters ON (5% level increase needed).

8. Given the following plant conditions:
  • The Control Room Team is performing E-3, "Steam Generator Tube Rupture" actions.
  • All systems function as designed.

Which ONE of the following will be the reason for verifying [2BDG*AOV100A1], "21A S/G Blowdown Outside CNMT Isolation Valve" automatically CLOSED?

To minimize A. S/G tube creep.

B. radiological releases.

C. 8P between ruptured and non-ruptured S/G's.

D. time to cover ruptured S/G U-tubes (promote thermal stratification).

Answer: B Explanation/Justification:

A. Incorrect. This is the reason for checking S/G water level during an ICC condition prior to starting RCPs. The candidate may confuse background document steps and isolating BID will increase S/G water level faster making this a plausible choice.

B. Correct. The affected S/G BID Isolation valve automatically closes on a high radiation level. The candidate must know the reason for this isolation according to the E-3 BIG document. This is the only automatic action in E-3 that has an automatic isolation signal provided by a process radiation monitor.

C. Incorrect. This is opposite of another reason for isolation of flow from the ruptured SfG. DP should be maximized as opposed to minimized.

D. Incorrect. Plausible that limiting blowdown will decrease the time to fill the S/G. E-3 does require S/G U-tubes covered prior to isolation of feedwater flow to the ruptured S/G. Establishing and maintaining water level above the U-tubes in the ruptured S/G promotes thermal stratification to prevent ruptured S/G depressuization. According to the BIG this is the reason for checking ruptured S/G level, not for isolating BID.

A. Incorrect. Incorrect number of S/Gs and flowrate. The reason and flowrate are plausible if the candidate confuses the FR-H.1 background with ECA-2.1 background.

B. Incorrect. Correct flowrate and reason but incorrect number of S/Gs.

C. Incorrect. Correct number of S/Gs with incorrect flowrate. The reason and flowrate are plausible if the candidate confuses the FR-H.1 background with ECA-2.1 background.background.

D. Correct. The candidate must know the background document bases for FR-H.1 information on how to restore feedwater flow to a hot dry S/G and understand the operational effect if this is not performed properly. Specifically. step 28 background states that a hot dry S/G is defined as having primary side ofthe S/G temperature> 525 F and <14% WR level. The background further states that the SIG water level should be restored to one S/G at a time and at a minimal flowrate not to exceed 100 gpm to minimize thermal stress.

11. Given the following plant conditions:

The Unit is operating at 100% power when a Station Blackout causes a reactor trip.

Twenty five (25) minutes after the trip, power has been restored to Emergency Bus 2AE ONLY.

The Control Room team has transitioned to ECA-0.1, "Loss of All AC Power Recovery Without SI Required".

  • T-hot is 585°F in all three (3) loops and slowly RISING.
  • T-cold is 555°F in all three (3) loops and STABLE.
  • All systems function as designed.

Based on these conditions, what is the status of RCS natural circulation heat removal?

Natural Circulation cooling is _ _ _ __

A. occurring and is being maintained by Condenser Steam Dumps.

B. occurring and is being maintained by S/G Atmospheric Steam Dumps.

C. NOT occurring and may be established by opening the S/G Atmospheric Steam Dumps.

). NOT occurring but forced cooling may be established by starting the "A" Reactor Coolant Pump.

Answer: C Explanation/Justification:

A. Incorrect. Natural circulation conditions do not exist lAW Attachment A-1.7. Condenser Steam dumps are unavailable.

B. Incorrect. Natural circulation conditions do not exist lAW Attachment A-1. 7. Atmospheric steam dumps are not maintaining heat removal.

C. Correct. Tcold is too hot for existing steam pressure. Steam temperature and Tcold should be about the same if natural circulation is present.

Without power to condenser cooling tower pumps, the condenser is unavailable and therefore atmospheric steam dumps must be used to increase steaming rate and thus establish natural circulation of the RCS through SIG cooling.

D. Incorrect. Correct that natural circulation does not exist, however, "A" RCP in not available since only Bus 2AE is available.

  • [2CHS-FI124A], "Seal Injection Flow" to "B" RCP is reading 8 gpm.
  • [2CHS-FI127A], "Seal Injection Flow" to "C" RCP is reading 8 gpm.

Based on these indications, which ONE of the following procedures will be entered?

A. AOP 2.38.1A, "Loss of Vital Bus 1".

B. AOP 2.38.1 B, "Loss of Vital Bus 2".

C. AOP 2.38.1 D, "Loss of Vital Bus 4".

D. E-O, "Reactor Trip or Safety Injection".

Answer: B Explanation/Justification:

Incorrect. Incorrect but plausible distractor if the candidate believes Train B RPS is powered from Vital Bus 1. The "A" RCP Thermal Barrier Valve is powered from VAC Vital Bus 1.

B. Correct. The candidate must analyze the stated plant conditions and determine which procedure to enter based on these conditions. Train B Reactor Protection System Trouble can be caused by Loss of Power. Train B is supplied by either Vital AC Bus 2 or 4. An additional indication that the candidate needs to correctly narrow down the correct procedure is that AC Vital Bus 2 supplies power to the "B" & "C" RCP thermal barrier isolation valves which explains why they are closed. (The valve indications are powered by associated Vital Bus so therefore flow was used as opposed to valve position). The RO is required to know AOP entry conditions.

C. Incorrect. Plausible power supply because the Train B RPS Trouble can be caused by either Vital Bus 2 or 4.

D. Incorrect. Plausible because if a loss of aU seal cooling occurs concurrently with a loss of CCP cooling to the thermal barrier, a reactor trip is required.

14. Given the following plant conditions:
  • The plant was operating at 100% power with all systems in NSA.
  • The Control Room Team manually tripped the plant based on excessive Steam Generator Tube Leakage.
  • Currently they are performing actions in E-3, "Steam Generator Tube Rupture".
  • While performing E-3 actions, the RO reports there are no Station Air Compressors running and instrument air pressure is dropping rapidly.

Which ONE of the following is the reason for restoring instrument air compressors according to the E-3 background document?

To ensure A. normal letdown and charging are available.

B. excess letdown and alternate charging are available.

C. intact S/G Main Steam Isolation Valves can be closed.

D. ruptured S/G Blowdown Isolation Valves can be closed.

Answer: A

xplanation/Justification

A. Correct. The candidate must know the reason why Instrument Air Compressors are verified running while in E-3. Without instrument air compressors a loss of instrument air will occur and the result is the inability to use normal letdown and charging as well as other support systems.

B. Incorrect. The BIG document specifically refers to restoring normal charging and normal letdown. Plausible because the EOP does allow the alternate use of excess letdown if normal letdown in unavailable and alternate charging if normal charging is unavailable. Incorrect because alternate charging does not require instrument air.

C. Incorrect. The MSIVs are designed to fail closed on a loss of instrument air. It is plausible that the intact S/G MSIVs are used to support E-3 actions and could be construed as a support system. Since MSIV are already closed, it is not necessary to restore air to close these valves.

D. Incorrect. Unit 2 S/G blowdown valves are supplied by Containment Instrument air which is supplied via station instrument air. It is plausible that the ruptured S/G blowdown valves are used for support system restoration in ES-3.2. These valves require air to open versus close.

  • Due to multiple equipment failures, the Control Room Team is performing actions of ECA-1.1, "Loss of Emergency Coolant Recirculation".
  • Two (2) Charging/HHSI pumps and two (2) LHSI pumps are running.
  • One (1) Quench Spray pump is running.
  • Containment pressure is 13 psig and SLOWLY dropping.
  • RWST Level is 20 inches and SLOWLY dropping.

Which ONE of the following describes the required action in accordance with ECA-1.1?

A. STOP ALL pumps taking suction from the RWST and verify no backflow from the RWST to CNMT sump.

B. STOP ALL pumps taking suction from the RWST and initiate secondary depressurization to facilitate SI accumulator injection.

C. STOP ONLY ONE (1) HHSI and ONLY ONE (1) LHSI pump and initiate secondary depressurization to facilitate SI accumulator injection. Secure the Quench Spray pump.

D. STOP BOTH LHSI pumps and ONE (1) HHSI pump. Maintain Quench Spray pump running until containment pressure is < 11 psig and then add makeup to RCS from alternate sources.

mswer: B Explanation/Justification:

A. Incorrect. Correct that all pumps are stopped. Incorrect plausible action, B. Correct. The RO candidate must know the overall mitigative strategy of ECA-1.1 and sequence of events. ECA 1.1 directs the operator to secure all pumps taking suction from the RWST when level is < 30 inches. Once stopped the procedure directs the operator to check if all intact S/Gs should be depressurized.

C. Incorrect. Incorrect but plausible that one HHSI and one LSHI pump are secured because one of the procedural mitigating strategies is to conserve RWST water and in fact the procedure does directs action to secure pumps. Correct that the crew will initiate secondary depressurization to facilitate SI accumulator injection. Also correct that the Quench Spray pump is secured.

D. Incorrect. Incorrect but plausible action to maintain one pump running as noted above.

D. (1) will NOT (2) [2RMF-RQ301] is designed to detect beta radiation (scintillation).

Answer: A Explanation/Justification:

A. Correct. The candidate must be able to determine and interpret the occurrence of a fuel handling incident as it applies to a fuel handling accident.

Specifically to answer the question they must have fundamental knowledge of the type of detEJclors in the Fuel Pool building and associated design. They must also have knowledge of the UFSAR accident analysis regarding Fuel Handling Accidents. The UFSAR analysis states quite clearly that activity will be released into the buildings (Fuel or Containment) for the a fuel handling accident of this type. Therefore both detectors will be in HIGH alarm.

B. Incorrect. Correct 2RMF-RQ301 response, however, the detector type is incorrect. 2RMF-301 is NOT a GM tube. Opposite of correct detector type.

C. Incorrect. The UFSAR analysis states quite clearly that activity will be release into the buildin~ls for a fuel handling accident of this type.

D. Incorrect. Even though the listed monitor type is correct (2RMF-301 is a scintillation detector), the fact that the area monitor went into an alarm condition implies that enough activity was released into the area to raise the activity level sensed in the ventilation duct.

A. Incorrect. Correct that asphyxiation is a major concern. Incorrect that halon is used in this space (refer to correct answer).

B. Incorrect. Water is not used in the East Cable Vault as part of any automatic suppression fire fighting systems and therefore flooding is not a major concern, C. Correct The candidate must know that C02 is the fire fighting agent used in the East Cable Vault to automatically distinguish fires. Water or Halon are NOT used in this area. The operational implications of a serious fire in the East Cable Vault is that C02 is a major concern when entering this space due to the safety hazards it may cause (ie: cardiac arrest or nervous system effects). Note that there are manual water hose stations in the area, however, the question is asking about automatic actions, Also in Unit 2 there are other annunicators which will alarm, however, they are excluded from the question stem to preclude guiding the candidate toward the correct answer.

D. Incorrect. Water is not used in the East Cable Vault as part of any automatic suppression fire fighting systems and therefore flooding is not a major concern. Plausible that water is used as a fire extinguishing agent and flooding would then become a concern.

  • [2CHS*RQ1 01 B], "Reactor Coolant High Range Monitor" has just reached its HIGH alarm setpoint.
  • Actions of 20M-43.4.AAC, "Radiation Monitoring Level High" have been completed.

Which ONE of the following reflects the desired plant line-up as specified in AOP 2.6.6?

A. Letdown demineralizers automatically bypassed.

B. Letdown automatically isolated on high radiation.

C. [2CVS-P21 AlB], "CNMT Vacuum Pumps" are BOTH running.

D. [2DGS-P21A1B], "Primary Drain Transfer Pumps" are BOTH in PTL.

Answer: D Explanation/Justification:

A. Incorrect. Plausible that the candidate may believe that letdown flow has been increased and this leads to higher temperature which auto bypasses the letdown demineralizers. AOP 2.6.6 directs putting more demins in service and rE!ducing letdown flow which is the desired lineup.

1. Incorrect. Plausible that letdown is isolated on a high radiation condition. The candidate must have knowledge that there is no automatic function provided by the radiation monitors which are in high alarm.

C. Incorrect. Plausible incorrect action which is opposite of that specified in AOP 2.6.6 which stops the containment vacuum pumps. The candidate may have a misconception about maintaining a negative pressure inside the containment to keep radiation from leaking to the outside environment. They must understand that this action although it would maintain a more negative pressure would draw some of the activity to the outside making matters worse, while the overall intent of the procedure is to minimize exposur,e and reduce radiological concerns.

D. Correct. The candidate must understand the desired plant lineup as specified in AOP 2.6.6 for a High RCS Coolant Activity condition. One of the actions specified in AOP 2.6.6 is to place both PDT pumps in PTL. The RO is required to know the overall mitigative strategies of procedures.

25. Given the following plant conditions:
  • The plant was operating at Full Power with all systems in NSA.
  • An unisolable Steam Line Break has necessitated a transition to FR-P.1, "Response to Imminent Pressurized Thermal Shock".
  • This transition was based on an Orange CSF Status Tree condition.

Which ONE of the following describes the action that will be taken in FR-P.1 and the reason for this action?

A. Depressurize the RCS to maximize SI flow to the core.

B. Stabilize RCS pressure to minimize SI flow to the core.

C. Depressurize the RCS to minimize pressure stresses on the reactor vessel.

D. Stabilize RCS pressure to minimize pressure stresses on the pressurizer.

Answer: C Explanation/Justification:

A. Incorrect. Maximizing SI flow would increase the cooldown and increase temperature stresses on the reactor vessel. Depressurizing the RCS is a correct action for the incorrect reason but correct effect.

B. Incorrect. SI flow is terminated if possible, however reactor vessel pressure is reduced to a minimum, decreasing the pressure stresses on the reactor vessel.

C. Correct. The candidate must have knowledge of the actions to reduce pressure and temperature effects in FR-P.i and reasons for these actions.

Specifically one of the major action categories is to depressurize the RCS to minimize pressure stress. According to the background document the reason for this action is to decrease pressure stress on the reactor vessel wall as much as possible.

D. Incorrect. System pressure is reduced to a minimum to decrease the pressure stresses on the reactor vessel versus pressurizer.

  • The Unit was operating at Full Power with all systems in NSA
  • A Large Break LOCA occurred.
  • The Control Room Team transitioned to E-1, "Loss of Reactor or Secondary Coolant".
  • All systems function as designed.
  • Containment pressure peaked at 35 psig and is now 10 psig and SLOWLY DROPPING.
  • Indicated RWST Level is 380 inches and DROPPING.
  • Assume no operator action related to equipment stated below.

Which ONE of the following describes what equipment currently will be in service for the containment pressure reduction?

A Recirc Spray ONLY.

B. Quench Spray ONLY.

C. Recirc Spray AND Quench Spray.

D. Quench Spray, Recirc Spray, AND Containment Air Recirculation Fans.

Answer: C Explanation/Justification:

1\. Incorrect Correct that Recirc spray is in service. Incorrect that it is the only equipment in service. (refer to correct answer explanation)

6. Incorrect. Correct that Quench spray is in service. Incorrect that it is the only equipment in service. (refer to correct answer explanation)

C. Correct. The candidate must analyze plant conditions and determine based on these conditions what components are functioning to automatically reduce high containment pressure caused by a LBLOCA. Specifically, the candidate must know that the Quench Spray pumps will start on a CIB signal which is caused when containment pressure increases above 11 psig. Note that current containment pressure is below 11 psig, but without operator action, these pumps will continue to run. E-1 directs the operator to secure these pumps at < 8.5 psig. The RSS pumps start upon an CIB signal plus RWST level < 381". At 380" these pumps are designed to AUTO start and therefore are running. The containment air recirculation fan automatically trips on a SI and/or sump level.

D. Incorrect. Containment air recirculation fans are tripped due to CIA actuation. The other two are correct. (refer to correct answer explanation)

28. Given the following plant conditions:
  • The Unit is operating at Full Power with all systems in NSA.
  • 21 B RCP UBLO CLG WTR DISCH FLOW, [2CCP-FT104B] indicates 185 gpm and is SLOWLY RISING.
  • 21 B RCP LBLO CLG WTR DISCH FLOW, [2CCP-FT106B] indicates 9.6 gpm and is SLOWLY RISING.
  • Containment temperatures as indicated on [2LMS*TI1 00-1,2,7,13,14, 15] are STABLE.
  • [2CCP-Ll100A(B)], "CCP Surge Tank Level" is SLOWLY DROPPING.

If the leak is on the inlet flange side of the 21 B RCP Stator Aiir Cooler Heat Exchanger, which of the following control room indications will confirm this leak location?

21 B RCP Stator Clg Water Disch Flow [2CCP-FT-1 05B]

21 B RCP Stator Winding temperatures on [2RCS*-TR-448B]

[2CCP-FT-1 05B] [2RCS-TR-448Bl A. increasing decreasing B. decreasing decreasing C. decreasing remains the same r increasin remains the same Answer: C Explanation/Justification:

A. Incorrect. If the candidate believes the flow transmitter is located on the inlet side of the HX th'9n it is plausible that 2CCP-FT-105B flow will be increasing. They may also have a misconception that if flow is increasing that stator temperature will decrease.

B. Incorrect. Correct flow indication. Incorrect but plausible stator temperature if the leak was on the outlet side of the HX where there would be more actual flow through the air cooler.

C. Correct. The candidate must be able to predict or monitor changes to 21 B Rep stator winding temperature and flow based on a leak upstream of the stator air cooler HX. They must understand the system layout and location of the flow tram;mitter in relation to the air cooler HX to derive the correct answer. Based on system design a large amount of air flow through the RCP Stator Air Cooler is from the Containment Recirculation Fans. The stem of the question states that containment temperature remains stable, so therefore the impact of this system leak is minimal.

Increasing is not used a distractor for stator winding temperature because it is difficult to asceltain the exact amount of cooling loss that would be needed to cause a stator temperature increase and could be challenged.

D. Incorrect. If the candidate believes the flow transmitter is located on the inlet side of the HX th'9n it is plausible that 2CCP-FT-1 05B flow will be increasing. Potentially correct stator winding temperature response. Refer to correct answer explanation.

A. RHS flow is affected because BOTH RHS pumps trip.

B. RHS flow continues to return to RCS "A" & "C" cold leg loops.

C. RHS flow continues to return to RCS "B" & "C" cold leg loops.

D. RHS flow is affected because all four inlet isolation valves AUTO close.

Answer: C Explanation/Justification:

Incorrect. This would be correct if a CIS were to occur. Since an inadvertent 81 occurred, there, is no reason to believe a high containment pressure condition exists.

B. Incorrect. Correct that RHS flow continues, however, the candidate may not know the SIS interrelationship is back to the B versus A cold leg common connection.

C. Correct. An SIS will not impact RHR system flow directly unless containment pressure were to increase greater than 11 psig (CIB) or a manual CIB signal were generated. AOP 2.6.9, "Inadvertent SI Actuation < 350 F does check RHR status because CCP flow will be effected to RHS because SIS causes a CIA which causes an isolation of CCP cooling to RHS HX's. RHS flow to the common loops where SIS and RCS tie together is however unaffected. The candidate must have knowledge of specific SIS signal calJse/effect relationships as well as the physical connection where they tie into a common SI return line to the RCS.

D. Incorrect. The inlet isolation valves do have auto close signals on high system pressure as opposed to an SI signal.

Which ONE of the following indications will confirm a Safety Valve is the cause of leakage AND what AUTOMATIC action will reduce PRT pressure if NO OPERATOR action were to occur?

PRZR Safety Relief line temperatures _ (1)_.

PRT Pressure will be reduced __ (2) __

A. (1) are RISING.

(2) when the PRT Rupture disc(s) blow.

B. (1) are consistent with PRZR temperature.

(2) when the PRT Relief Valve(s) open.

C. (1) are RISING.

(2) when [2RCS-AOV519], "Makeup Water to PRT Valve" opens ONLY.

D. (1) are consistent with PRZR temperature.

(2) when BOTH [2RCS-AOV519] AND [2RCS-MOV516] PRT Spray Valves open.

Answer: A Explanation/Justification:

A. Correct. The candidate must be able to analyze the conditions provided and apply system knowledge. For the conditions provided a leaking PRZR or Safety Valve do discharge to the PRT and rising temperatures are indicative of discharge to the PRT. Correct that PRZR Safety Relief line temperature is rising. The PRT rupture disk(s) will automatically rupture to reduce PRT pn~ssure.

B. Incorrect. Incorrect but plausible misconception of isenthalpic processes (TMI). Correct that the PRT relief valve functions to lift before the rupture disk(s) is (are) blown.

C. Incorrect. Correct PRZR Safety line temperature response. 2RCS-AOV519 is procedurally used to lower pressure. however, it is not an automatic action in Unit 2.

O. Incorrect. Incorrect PRZR Safety line temperature response. 2RCS-AOV519 and 2RCS-MOV516 are procedurally used to lower pressure, however, it is not an automatic action in Unit 2.

35. Given the following plant conditions:
  • The Unit is at Full power with all systems in NSA.
  • A6-1H, "PRIMARY COMPONENT COOLING WATER SYSTEM TROUBLE" is received and acknowledged.
  • [2CCP-Ll-100A & 100B] "CCP Surge Tank level" is 70 inches and slowly RISING.
  • A2-5F, "REACTOR COOLANT PUMP COOLING WATER TROUBLE" is received several minutes later.
  • No operator actions occur and plant systems function as designed.

Which ONE of the following CCP flow indications confirms the cause of these plant conditions?

A. 2CCP-FT106A, "RCP 21A LBLO CLG FLW LOW".

B. 2CCP-FT107A, "RCP 21A TH BARR FLW HIGH".

C. 2CCP-FT104A, "RCP 21A UBLO CLG FLW LOW".

D. 2CCP-FT106A, "RCP 21A LBLO CLG FLW HIGH".

Answer: B Explanation/Justification:

A. Incorrect. This is a plausible alarm which will cause A2-SF to annunciate, however, A6-1H annunciated due to high surge tank level and a low flow condition will not cause this condition and is more indicative of a system rupture in which case CCP surge tank level would be reading low.

Correct. The candidate must be able to predict based on the set of annunciators and paramet'9r provided that the only correct CCW flowrate which can cause this set of conditions is high thermal barrier flow rate. AS-1 H has various inputs. The candidate must deduce that the high surge tank level was the cause of this alarm. although several other conditions can cause AS-1 H to annunciate. They must also understand that the only condition related to the RCP which will cause level to increase is a leak from the RCP thermal barrier into the CCP system.

C. Incorrect This is a plausible alarm which will cause A2-5F to annunciate, however. A6-1H annunciated due to high surge tank level and a low flow condition will not cause this condition and is more indicative of a system rupture in which case CCP surge tank level would be reading low.

D. Incorrect. A high flow condition will not bring A2-SF into alarm. The candidate must understand that even if there were a high flow condition. that this flow rate would not impact the CCP surge tank level and is not due to an intersystem leak.

  • The Unit is at 100% power with all systems NSA EXCIEPT:

o 2RCS-PCV-455A, "PRZR Spray Valve" is in its FAIL position due to a broken air line AND the Proportional Heater is in PTL.

  • RCS Tavg is 578°F and STABLE.
  • 2RCS*PT444, "Pressurizer (PRZR) Control Channel", fails HIGH over a ONE (1) minute period.

With no operator action, which ONE of the following describe-s how the PRZR Pressure Control System will respond?

A. TWO (2) PRZR PORVs will be OPEN.

B. ONE (1) PRZR PORV and ONE (1) PRZR Spray Valve will be OPEN.

C. ALL PRZR BtU heaters will be ON and BOTH PRZR Spray Valves will be CLOSED.

D. ALL PRZR BtU heaters will be OFF and ONE (1) PRZR Spray Valve will be in NSA position.

Answer: B Explanation/Justification:

1\. Incorrect. These indications are indicative of 2RCS'PT445 failing in the high (lirection. Plausible if the candidate confuses the PRZR pressure control system inputs or does not understand the impact of the items which are OOS for this system.

B. Correct. A failure of 2RCS'PT444 in the high direction will typically result in 2RCS-PCV-455C opening and both PRZR spray Valves failing full open. 2RCS-PCV-455A fails closed on a loss of air, therefore only 2RCS-PCV-455B will open.

C. Incorrect. This is indicative of 2RCS'PT444 failing in the low direction.

D. Incorrect. Correct PRZR BIU heater response except that NSA two heaters will be ON, so therefore not all heaters will be OFF. At 100% power, 2RCS-PCV-455A is typically slightly open. Since it is failed closed, it is not NSA. The other spray valve will be opening and it is plausible based on the integral impact of the failure on the master pressure controller which makes it difficult to ascertain the exact valve position.

  • The Unit is operating at 45% power with all systems in NSA for this power level.
  • Testing is in progress on Train "B" of SSPS.
  • The "B" Reactor Trip Bypass Breaker is racked-in and closed.
  • All systems function as designed.
  • No operator action occurs.

Which ONE of the following will be the response of the Reactor Protection System AND the effect on the Turbine Generator?

A. Only the "A" Reactor Trip Breaker will open; The Turbine Generator will trip.

B. Only the "A" Reactor Trip Breaker will open; The Turbine Generator will NOT trip.

C. Both the "A" Reactor Trip Breaker AND the "B" Reactor Trip Bypass Breaker will open; The Turbine Generator will trip.

D. Both the "A" Reactor Trip Breaker AND the "B" Reactor Trip Bypass Breaker will open; The Turbine Generator will NOT trip.

Answer: C Explanation/Justification:

A. Incorrect. Plausible if the candidate does not understand the RPS logic that they may believe only the "A' RTB opens. Correct turbine status.

B. Incorrect. Plausible if the candidate does not understand the RPS logic that they may believe only the UN RTB opens. Incorrect turbine status.

C. Correct. The candidate must have knowledge of the effect that a malfunction of the RPS (Train A functions ONLY) and resultant effect on the Turbine Generator. The candidate must have knowledge of the RPS breaker configuration (RPS KIA). In the current plant configuration an "An Train reactor trip signal will open both the "A" RTB and BYB. The turbine will trip because the reactor tripped.

  • All required actions directed by the Instrument Failure Procedure were completed.
  • Subsequently, 2LMS*PT951 fails high.

What will be the CIB and Safety Injection response, if any?

A. Both CIB and Safety Injection actuate.

B. CIB actuates but Safety Injection doesn't.

C. Neither CIB or Safety Injection actuate.

D. Safety Injection actuates but CIB doesn't.

Answer: C Explanation/Justification:

A. A. Incorrect. Refer to correct answer explanation, B. B. Incorrect. Refer to correct answer explanation.

C. C. Correct. The candidate must recognize that the initial failure was on CH-1. The stem states that all required actions of the IF procedure have been completed, which means that the CH-I input to the CIB actuation circuitry has been bypElssed which changes the actuation logic from 2/4 to 2/3. Upon a subsequent failure of a 2nd channel, (CH-II), NO CIB actuations will occur because only 1 of 3 Channels have seen the failure. CH I does not provide input to Safety Injection actuation circuitry, so therefore when CH II fails it does not satisfy the 2/3 logic required for Safety Injection to actuate, therefore no SI actuation occurs. All distractors are plausible if the candidate does not know SSPS logics or impacts of these failures upon the system.

[2HVR*FN201 A] [2HVR*FN201 C]

A. RUNNING RUNNING B. RUNNING NOT RUNNING C. NOT RUNNING NOT RUNNING D. NOT RUNNING RUNNING Answer: B xplanation/Justification:

A. Incorrect. Correct that 2HVR*FN201A is funning, however, 2HVR*FN201 C is tripped. Plausible because 2HVR*FN201 C can be selected to either power supply.

B. Correct. 2HVR*FN201A is powered from Bus 2N, 2HVR*FN2018 is powered from Bus 2P ancl2HVR*FN201C can be powered from either 2N or 2P. In the stated plant conditions 2HVR*FN201C is running. Since 2HVR*FN201A is being supplied from 2N, NSA would dictate that 2HVR*FN201C would be aligned to the 2P bus to allow train separation. If 2P is lost then 2HVR*FN201A will be the only running containment air recirc fan.

C. Incorrect. Correct that 2HVR*FN201C is not running. Incorrect that 2HVR*FN201A is not running.

D. Correct. The candidate must know the design features for cold leg recirculation swapover and be aware of how these realignments by design impact minimizing the escape of radioactivity from the containment to the RWST. The question is asking which of the alignments does not prevent release, so therefore the candidate must sort through each alignment before deducing that although 2SIS*MOV8811A1B open and 2RSS*MOV156C/D close, this realignment does not preclude release to the RWST but rather is more to align flow to the LHSI header to maximize recirculation of sump water back to the core for cooling.

D. (1) 100°F/hr (2) TS & LRM limits are not exceeded.

Answer: C

.=xplanation/Justification:

A. Incorrect. 50 F/hr is a cool-down rate specified in accordance with 20M-52.4.R.1 F to initially begin RCS C/O but is not the maximum allowable rate. Correct reason for limit.

B. Incorrect. 60 F/hr is the maximum allowed heatup rate in accordance with 20M-52.4.R.1 F. Correct reason for limit.

C. Correct. 90 F/hr is the TS maximum allowed administrative C/O limit allowed by 20M-52.4.R.1 F. The basis of this C/O rate is so the RCS is not operated under conditions that can result in brittle fracture of the RCPB. Violating LCO limits places the reactor vessel outside the bounds of the stress analyses. The LCO establishes operating limits that provide a margin to brittle failure of the reactor vessel and piping of the Reactor Coolant Pressure Boundary. So therefore the limit is to ensure TS & LRM limits are not exceeded.

B. (1) 700 (2) liB" Header ONLY.

C. (1)700 (2) "A" Header ONLY.

D. (1) 900 (2) "A" AND "B" Headers.

Answer: C Explanation/Justification:

A. Incorrect. Incorrect capacity. Correct header. Plausible if the candidate does not know the capacities or misunderstands the initial plant conditions.

One validator chose this dlstractor based on confusing the AFW pump capacities.

B. Incorrect. Correct capacity. Incorrect header. Plausible if the candidate believes NSA is to the "8" header or believes the impact of 2FWE*P23A is realignment of 2FWE-P22 to the "8" header.

C. Correct. A loss of offsite power coincident with a turbine trip results in a reactor trip and subsequent loss of both MFW pumps. The EDGs are designed to start on a loss of power to AE and OF bus which will power both electric AFW pumps. In the stated conditions, with an overcurrent condition on the OF bus, 2FWE*P23B will not have power. Since 2FWE*P23A is already OOS, only 2FWE-P22 (Turbine Driven AFW pump) will start to provide approximately 700 gpm AFW flow. The AFW system is designed to feed all three S/G based on NSA alignment requirements.

NSA has 2FWE-P22 aligned to the "An Header.

D. Incorrect. Correct capacity. If the candidate does not know the capacities or understand the impact based on initial plant conditions, then it is plausible that AFW flow would be provided through the "A" header by 2FWE-P22 and the "B" header by 2FWE*P23B. In this case the total flow will be 900 gpm based on limiting orifices which limit flow to 300 gpm per S/G. Incorrect because 2FWE*P23B has no power.

  • The plant is in Mode 3 following a reactor trip from an extended 450 day run.
  • A 50 °F/hr cool down from 547 of has just begun.
  • S/G NR Water Levels are being maintained constant at 44% using AFW.

Which ONE of the following describes the required AFW flow trend required to maintain a constant RCS cool down rate to Mode 5?

A. AFW flow requirements will be constant as long as the C/O rate remains constant.

B. More AFW flow will be required to maintain S/G Water Level due to decreased density.

C. AFW flow requirements will be constant as long as S/G Water Level remains constant.

D. Less AFW flow will be required to maintain S/G Water Level because heat input to S/Gs drops.

Answer: 0 Explanation/Justification:

A. Incorrect. Eventually as the cool down continues, RHS will be placed in service which will reduce the steaming rate if the cool down rate is maintained constant. Less steam requires less AFW flow.

B. Incorrect. Density will increase versus decrease, Plausible that to maintain a constant cool down, that the steaming rate must increase, so therefore, more AFW flow seems plausible.

C. Incorrect. It requires less feedwater to maintain a constant S/G water level as the RCS cooldown continues. Otherwise, AFW pumps would be adequate for full power operation.

I. Correct. This is an operational fundamental question that requires the candidate to simply understand that decay heat rate drops over time.

8. Turbine driven pump running with flow> 340 gpm required.

C. Motor and Turbine driven pumps running with no flow requirements.

O. Motor and Turbine driven pumps running with flow> 340 gpm required.

Answer: A Explanation/Justification:

A. Correct The candidate must be able to analyze plant conditions and apply the conditions to the automatic start status of the AFW pumps.

Specifically they must monitor changes in S/G water level as well as other parameters to determine which AFW pumps have started and also determine heat sink requirements based on these S/G levels. None of the start permissives have been met to auto start the motor driven AFW pumps. The Turbine AFW pump has started on low S/G water level in "8" S/G due to water level being < 20.5% (2/3 lo-lo S/G levels on 1/3 S/Gs). Since "A" & "c" S/G have >12% (31 %) with no adverse containment, then no flow is required to meet heat sink requirements. All distractors are plausible if the candidate does not properly apply the auto start permissives for the AFW pumps (Motor Driven AFW Pumps require 2/3 lo-lo S/G levels on 2/3 S/Gs). Unit 2 requires >12% in any S/G or 340 gpm total feedwater flow for heat sink lAW F-0.3 Heat Sink.

45. Given the following plant conditions:
  • The Unit is operating at Full Power with all systems in NSA.
  • The 2-1 EDG is paralleled to the grid, carrying about 50% load.
  • The RO places the 2-1 EMERG GEN VOLTAGE ADJUST control switch to RAISE.

Which ONE of the following describes the result of placing the 2-1 EMERG GEN VOLTAGE ADJUST control switch to RAISE?

Indicated A. grid voltage rises; EDG speed remains the same.

B. grid voltage rises; EDG speed droops as load rises.

C. reactive load rises; EDG speed remains the same.

D. reactive load rises; EDG speed droops as a function of load.

Answer: C Explanation/Justification:

'\. Incorrect. Parallel operation of an EDG with a large power grid is such that adjusting voltage of the smaller machine will have no impact on the larger power grid. Correct that EDG speed remains the same.

B. Incorrect. Parallel operation of an EDG with a large power grid is such that adjusting voltage of the smaller machine will have no impact on the larger power grid. Plausible that the EDG speed droops since it is in the Droop mode when paralleled with off site power sources.

C. Correct. The candidate must understand from performing this OST in the simulator or in plant the impact of making adjustments during parallel operations of the EDG and offsite power sources. As the voltage adjust control switch is taken to raise, KVARs increase and there is no impact on EDG speed even though it is operating in the Speed Droop mode because it is paralled with an infinite power source.

D. Incorrect. Correct that reactive load rises. Incorrect but plausible since the EDG is in the speed droop mode and if candidate confuses mode of operation.

46. Given the following plant conditions:
  • The Unit is operating at Full Power with all systems in NSA.
  • A1-1C, "VITAL BUS INVERTER OPERATIONITROUBLE" annunciator is received.
  • Computer address V01 01 D indicates Vital Bus 2-1 INV TROUBLE.
  • Nuclear Instrumentation on NI-41 rack is energized.
  • Once dispatched the NLO reports Inverter failure is indicated on [UPS*VITBS2-1].

Assuming the system functioned as designed and no operator action has occurred, which ONE of the following will be the impact on Vital Bus 2-1 Loads?

Vital Bus 2-1 Loads _ _ __

A. are being supplied by 125 VDC SWBD 2-1.

B. are being supplied by an alternate source (MCC2-E05) via static switch.

C. are being supplied by an alternate source (MCC2**E08) via static switch.

D. are NOT being supplied until the static switch is manually transferred.

Answer: B Explanation/Justification:

\. Incorrect. Plausible because this would be the supply of power for a rectifier failure. Indications provided do not support this as the cause. Since A1-1 C is a common annunciator, the plant computer would have a different message specifying Vital Bus 2-1 Batt Operating which indicates a rectifier failure as opposed to a inverter failure has occurred.

B. Correct The candidate must know the system design for the UPS power sources. They must understand the indications provided in the question stem as noted above. On a loss of UPS inverter, a static switch is designed to automatically swap over to an alternate source of power which will be from MCC2-E05.

C. Incorrect. Correct that Vital Bus 1 will be supplied by an alternate source via a static switch, hc)wever, the candidate must know that MCC2-E07 is the alternate power supply to Vital Bus 4 versus Bus 1.

O. Incorrect. Plausible if a complete loss of power to Vital Bus 1 occurred, however, the candidate must recognize that with NI41 energized that there is still power to rule out this choice.

  • The plant is operating at Full Power with all systems in NSA.
  • Multiple control room alarms and indications simultaneously occur.
  • The following indications exist:

o All Rod Bottom Lights are LIT.

o All Main Steam Isolation Valves are closed.

o Loss of benchboard indicating lights for loads on 4KV Bus 2AE and 4S0V Bus 2 SN.

o Letdown flow indicates ZERO (0).

  • All systems function as designed.
  • No operator actions have yet occurred.

Based on these plant conditions, which ONE of the following is the cause of these plant conditions?

A. A Loss of 4S0V Bus 2N occurred.

B. A Loss of 125VDC Bus 2-1 occurred.

C. A Loss of 125VDC Bus 2-2 occurred.

D. A Loss of 120VAC Vital Bus 1 occurred.

,nswer: B Explanation/Justification:

A. Incorrect. Plausible since it has some commonalities. The reactor would not trip for this condition.

B. Correct. The candidate must be able to evaluate the plant conditions and make an operational judgment based on indications provided related to the DC Electrical System. The judgment necessary to be made is the cause of plant performance or conditions provided in the stem. The candidate must recognize that the reactor is tripped based on all rod bottom lights lit. A Loss of DC Bus 1 will result in an automatic reactor trip due to MSIV's closing. An automatic letdown isolation will occur. Another non direct symptom provided is Loss of Benchboard lights for loads on 2AE and Bus 8N.

C. Incorrect. Plausible since all of the indications are the same for a Loss of DC Bus 2 with the exception of the opposite bus 2DF and 9P are impacted.

D. Incorrect. Plausible if the candidate confuses a Loss of Vital Bus 1 with a Loss of DC Bus. Letdown will isolate in both cases.

48. Given the following plant conditions:
  • The Unit is operating at 100% power with all systems in NSA.
  • A8-10A, "125V DC Bus 2-1 Ground" is received and acknowledged.
  • The Control Room Team references 20M-39.4.F, "CIE~aring Grounds (125 VDC Buses 2-1 and 2-2)".

Which ONE of the following is the impact if more than one ground exists AND what action will be taken to preclude this impact according to this procedure?

The impact of multiple DC grounds is that __ (1) _ _.

To preclude this impact _ _ (2)

A. (1) inadvertent actuations may occur.

(2) de-energize DC Bus 2-1 until grounds are located.

B. (1) inadvertent actuations may occur.

(2) open knife switches or breakers prior to resetting relays.

C. (1) control functions may not occur when called upon.

(2) de-energize DC Bus 2-1 until grounds are located.

Answer: B Explanation/Justification:

A. Incorrect. Correct impact according to 20M-39.4.F. Incorrect but plausible action. Grounds an~ located by isolating individual components supplied by DC-Bus 2-1. If the entire bus were de-energized it would be difficult to locate and isolate the ground.

B. Correct. The candidate must be able to predict the impacts of multiple DC grounds on DC Busi 2-1. According to 20M-39.4.F, the impact of multiple grounds is that inadvertent actuations may occur. BVPS has had some actual OE regarding this issue. The candidate must also be able to use procedures to control the impact of multiple grounds. According to the precautions and limitations of the same reference, the method of control is to open knife switches or breakers prior to resetting relays.

C. Incorrect. Correct impact not referenced in our procedure, however, from research it is also possible with a DC ground that control functions may not operate when called upon depending on the resistance of the circuit. Incorrect but plausible action as explained in A above.

D. Incorrect. Correct impact not referenced in our procedure, however, from research it is also possible with a DC ground that control functions may not operate when called upon depending on the resistance of the circuit.

49. Given the following plant conditions and sequence of events:
  • The Unit suffered a Loss of Off-Site Power.
  • Grid stability is confirmed and the Operations Manager has granted permission to return to the grid.
  • The Control Room Team is performing 20M-36.4.E, 'Transferring 4KV Emergency Bus 2AE to Bus 2A".
  • EDG 2-1 is being synchronized to the grid and ACB 2E7 is closed.
  • Upon ACB 2E7 closure, the following annunciator sequence occurs:

o A8-2B, "4160V EMER BUS 2AE ACB 2E7 OVERCURRENT TRIP" received.

o A8-2A, "4160V EMER BUS 2AE ACB 2A10/2E'7 AUTO TRIP" received.

o A8-2B, "4160V EMER BUS 2AE ACB 2E7 OVERCURRENT TRIP" clears.

Which ON E of the following describes the impact on EDG 2-1?

EDG 2-1 will _ _ _ _ cooling water available.

A. trip with B. trip without C. continue to run with

). continue to run without Answer: C Explanation/Justification:

A. Incorrect. EDG 2-1 does not trip but remains running. Plausible that the EDG would trip on an overcurrent condition, however, protection in this scenario is provided by ACB 2E7. Correct that cooling is still available.

B. Incorrect. EDG 2-1 does not trip but remains running. Plausible that the EDG would trip on an overcurrent condition, however, protection in this scenario is provided by ACB 2E7. Also incorrect that cooling water is not available.

C. Correct. For the given conditions, EDG 2-1 is running paralleled to the grid. An overcurrent condition was caused by the closure of ACB2E7 and results in ACB 2A10 & 2E7 automatically opening. Upon ACB-2E7 opening, the overcurrent condition clears which is indicative oflhe problem being downstream of ACB 2E7. The EDG will continue to run with cooling since ACB2E10 remains closed and EDG cooling would be maintained from the running "A" Train SW pump being supplied by the AE Bus powered by the EDG. It is not RO knowledge to select procedures so therefore only the first part of the higher cognitive KIA was tested. For purposes of satisfying the KIA, the Aux Feeder Breaker is the 2E7 breaker to the AE bus.

D. Incorrect. Correct that EDG 2-1 remains running, incorrect that it is running without cooling. Plausible if the candidate believes the overcurrent trip opens ACB 2E10 and does not recognize or understand the RW system configuration. If the EDG did trip the opposite train SW cooling would need to be manually aligned.

51. Given the following plant conditions:
  • The plant is operating at 100% with all systems in NSA
  • A liquid waste discharge is in progress to the Unit 1 Cooling Tower Blowdown.
  • [2SWS-RQI102], "Component Cooling HX SW" fails upscale HIGH.
  • [2CCP-RQI100], "Component Cooling Water" is reading normal and is unchanged.
  • The following alarms are received:

o A4-5A, "RADIATION MONITORING SYSTEM TROUBLE" o A4-5C, "RADIATION MONITORING LEVEL HIGH"

  • On RM-11, it is confirmed that COMPONENT COOLING HX SW [2SWS-RQI102] is blinking RED.
  • No other alarms are present and no operator action has occurred.
  • All systems function as designed.

What will be the impact of this process monitor failure on the effluent release in progress?

A. The release will automatically terminate immediately.

B. The release will continue and IS required to be manually terminated.

C. The release will automatically terminate after a short time delay.

D. The release will continue and is NOT required to be manually terminated.

"nswer: D Explanation/Justification:

A. Incorrect. Plausible if the candidate confuses this monitor with 2SGC-RQ1 00 which would reslJlt in auto termination if an upscale failure occurred, B. Incorrect. Correct that release will continue and plausible but incorrect that the release must be manually terminated, The candidate must understand system interrelationships. With CCP in normal there is no reason to believe there is any radiation coming from the CCP system into the SW system.

C. Incorrect. Plausible if the candidate confuses this monitor with 2SGC-RQ100 which would reslJlt in auto termination if an upscale failure occurred and they also confuse or do not know that there is no time delay with this failure.

D. Correct. The candidate must understand how the failure of 2SWS-RQI1 02 will impact the effluent release in progress. There is no automatic action associated with this radiation monitor. Therefore an upscale failure will have no impact on the release. The candidate must also know the system interrelationships between CCP and SW. Ifthere were a leak from the RCS into CCP, then there would be an alarm from 2CCP-RQI100.

The ARP does not require any release to be terminated.

B. 3 AND 4 ONLY.

C. 1 AND 2 ONLY.

I. 1,2, AND 4.

Answer: 0 Explanation/Justification:

A. Incorrect Both B HHSI pump and B Control Room Ventilation will have cooling. This is incorrect because the A HHSI pump will also have cooling.

Plausible if the candidate does not know about the auto start feature of A ESW for A header restoration.

B. Incorrect. LHSI pumps are cooled by local air cooling and require no service water cooling. Pla,usible if the candidate confuses LHSI and HHSI pump cooling. Correct that B Control Room Ventilation has SW cooling, C. Incorrect. Correct that A & B HHSI pump wi" have cooling. Plausible if the candidate knows that LHSI pumps do not receive SW cooling and is unaware of the cooling medium to the B Control Room Ventilation, D. Correct. Service Water provides cooling to the charging pump lube oil coolers. These pump become the High Head SI pumps on a SI signal.

When the A" SW Pump tripped, a low pressure condition occurred resulting in an AUTO start clf the "A>> Emergency Service Water Pump which restores cooling to the "A" SW header. Therefore both High Head SI Pumps will have SW available, Control Room Ventilation is another emergency heat load which will have SW cooling.

A. 1 ONLY.

B. 1 AND 2 ONLY.

C. 3 AND 4 ONLY.

D. 1.2. AND 3 .

  • nswer: A ExplanationlJustification:

A. Correct. 2IAC-MOV131 and 21AC*130 are open at 100% power to supply instrument air from instrument air compressors into containment. BVPS Unit 2 no longer uses containment air compressors. Upon a large break lOCA and 51 and subsequent CIA signal will auto close 2IAC*130. In order to restore instrument air to containment, this valve needs to be reopened only.

B. Incorrect. Correct that 21AC*MOV130 needs to be reopened. Plausible if the candidate does not know that 2IAC*MOV131 does not receive a CIA signal or believes this valve is affected by this signal. The EOP directs both of these valves opened, however, the EOP deals with all modes of operation and in the stated plant mode, the candidate must know it is not necessary to reopen 2IAC-MOV131.

C. Incorrect. 2IAC*MOV133 & 134 both receive a CIA Signal and close. This was the old configuration when running CNMT lAC instrument air to containment. Opening these valves will not restore IA to containment.

D. Incorrect. All three of these valves receive a CIA Signal and close from their NSA open positions. The candidate may believe that these valves all need to be reopened to restore instrument air.

Which ONE of the following will be the status of the Containment penetration lines for the Phase "A" (CIA) and Phase "B" (CIB) isolation valves AND what operator action is required, if any?

A. All CIA & CIB valves close. No operator action is required.

B. Train "A" CIA & CIB valves close. Operators must manually isolate Train "B" CIA & CIB valves.

C. All CIA valves close. All CIB valves do NOT reposition. Operators must manually isolate CIB valves.

D. Train "A" CIA valves close. All CIB valves do NOT reposition. Operators must manually isolate Train "B" CIA valves ONLY.

Answer: 0 Explanation/J ustification:

A. Incorrect Plausible if the candidate believes that either train will isolate both trains CIA & CIB isolation valves in which case there would be no need for operator action. (refer to correct answer explanation)

Incorrect. Correct that Train A CIA valves are closed. Incorrect that Train A CIB valves are closed. Plausible action that the operators would close the Train B valves if they failed to isolate.

C. Incorrect. Plausible if the candidate believes only one train isolates all CIA valves & CIB requires both trains in which case there would be a need for operators to close CIS valves. Either manual CIA will isolate both trains. (refer to correct answer explanation)

O. Correct. The candidate must be able to analyze the stated plant conditions and be able to app:iy knowledge of how a Train A SI will effect CIA and CIS.

58. An internal fault (short circuit) occurs in the PRZR Press Control [2RCS-PK444A] Controller.

Which ONE of the following describes the effect this fault will have on the Reactor Protection System?

The CONTROLLER fault could - - - - -

A. NOT directly feed back into the protection circuit due to use of isolation devices.

B. directly feed back into the protection circuit, causing the SELECTED channels to trip.

C. directly feed back into the protection circuit, preventing the SELECTED channels from tripping.

D. NOT directly feed back into the protection circuit since separate transmitters are used for control and protection.

Answer: 0 Explanation/Justification:

A. Incorrect This is the design feature for PRZR Level control circuit but is not the same for the pressure control/protection circuit B. Incorrect. PRZR pressure control is separate from the protection and do not have isolation amplifiers. The candidate could confuse PRZR Level circuitry with PRZR pressure circuitry. The transmitters do share common taps off of the same' instrument line. A PRZR pressure reference controller failure will indirectly have an impact on actual PRZR pressure so therefore will impact RPS indirectly.

C. Incorrect. PRZR pressure control is separate from the protection and do not have isolation amplifiers. The candidate could confuse PRZR Level circuitry with PRZR pressure circuitry. The transmitters do share common taps off of the same, instrument line. The candidate may focus on whether the fault causes reference pressure to fail high or low which makes B & C distractors plausible.

D. Correct. The candidate must have knowledge of the operational implications of separation of control and protection circuits for non-nuclear instrumentation. Specifically, they must have knowledge of how a fault on the NNIS (control side of PRZR pressure) impacts RPS (protection side of PRZR pressure). PRZR pressure uses separate transmitters so therefore the NNIS does not directly feedback into the Reactor Protection circuitry. Indirectly a failure of the reference PRZR pressure controller could impact actual plant pressure and therefore indirectly effect RPS.

A. (1) remain reliable (2) superheated.

B. (1) remain reliable (2) saturated.

C. (1) become less reliable since adverse conditions exist (2) saturated.

D. (1) become less reliable since adverse conditions exist (2) superheated.

Answer: B Explanation/Justification:

A. Incorrect. Correct status of CET's. Incorrect RCS condition. Misapplication of the conversion from psig to psia is a common fundamental problem.

B. Correct. The candidate must be able to predict or monitor changes in core exit temperature as the containment conditions degrade. They must also be able to apply the thermocouple reading to obtain correct condition of the RCS. 900 psia corresponds to 532 F. which means the RCS is in a saturated condition. Misapplication of the conversion will result in a different end result.

C. Incorrect. Plausible as containment conditions become more adverse that instrumentation will become less accurate. The CETs are designed to operate in this type of environment. Correct RCS condition.

D. Incorrect. Plausible as containment conditions become more adverse that instrumentation will become less accurate. The CETs are designed to operate in this type of environment. Incorrect but plausible RCS condition, if the candidate does not know how to use steam tables.

60. Given the following plant conditions:
  • A Plant Startup is in progress.
  • Reactor power is currently at 23%.
  • [2MSS-PK464], "Main Stm Manifold Pressure Control" is in AUTO with Zero (0) demand.
  • Steam Dumps are in the Tavg Mode.
  • Main Feedwater Regulating Bypass valves are in AUTO.

Which ONE of the following describes the steam dump and S/G NR Water Level response to the turbine trip, assuming NO operator actions?

Steam Dumps will (1)_

S/G NR Water Level will_ (2) _

A. (1) open and close.

(2) drop and then rise.

B. (1) open and remain open.

(2) rise and then drop.

C. (1) open and remain open.

(2) drop and then rise.

D. (1) remain closed.

(2) remain at programmed level.

Answer: C Explanation/Justification:

A. Incorrect. Correct that steam dumps open, however, the candidate must understand that with control rods in manual, that the increased Tavg caused by the turbine trip will not be reduced until the operators insert control rods. Therefore the steam dumps will remain open until Tavg is reduced to Tref. Correct S/G water level response.

B. Incorrect. Correct steam dump response. Opposite S/G water level response.

C. Correct. The candidate must analyze the plant conditions and understand steam dump operation and S/G water level response. With steam dumps in Tavg Mode initially, they would be closed. When the turbine trips, Tavg increases and the steam dumps will open based on temperature difference between Tref as sensed by first stage pressure and Tavg (C-7A Load Rejection Arms). The steam dumps will remain open until the operator inserts control rods to lower Tavg. S/G water level will initially drop to due to a decrease in steam demand (turbine trip). Once the steam dumps open in response to increasing Tavg, the S/G water level will begin to increase due to increase in steam demand which leads to S/G swell.

Also note that there are other dynamics in play such as SGWLC. With Bypass valves in auto, the SGWLC system will respond by opening the bypass valves which will increase feedwater flow and also increase S/G water level. The tie between steam dumps and SIG water level is the change in steam demand.

D. Incorrect. Incorrect steam dump response if the candidate believes they will not operate based on stated plant conditions. It is plausible that if the Steam dumps do not open that S/G water level would be unaffected since there would be no change in steam demand.

A. 0 ppm B.  ;::: 495 ppm C.  ;::: 1050 ppm D.  ;::: 2000 ppm Answer: 0 Explanation/Justification:

A. Incorrect. Plausible because it is the TS 4.0 design features value mentioned in section 4.3.1.2.b. Unit 2 can only maintain Keff ~ 1.0 without crediting soluble boron.

B. Incorrect. Plausible because it is the TS 4.0 design features value mentioned in section 4.3.1.c.

C. Incorrect. Plausible since it is the TS 3.7.16 Unit 1 number.

D. Correct. The candidate must have knowledge of the Spent Fuel Pool Cooling Design features/interlocks which ensures adequate SID margin (Cb concentration). Unit 2 is currently undergoing a major rerack project. Some of these numbers 11ave been incorporated into our Technical Specifications and therefore even though the project may not complete by the time 2LOT8 takes the ILT exam. we are testing current TS's.

According to TS 3.7.16, Unit 2 requires 2000 ppm to ensure Keff ~ 0.95. This is a conservativE' value to ensure no credible boron dilution event will reduce boron concentration below 450 ppm. This is RO level of knowledge since it tests LCO knowledge.

  • Unit 2 is in Mode 6 during a refueling outage.
  • The Containment Equipment Hatch is closed.
  • Fuel Movement is in progress.
  • Containment Purge is in operation and NO features have been defeated.
  • [2HVR*RQ104B]. Containment Purge Radiation Monitor fails upscale HIGH.
  • [2HVR*RQ104A]. Containment Purge Radiation Monitor is unaffected.
  • All systems function as designed.
  • No operator action has occurred.

What will be the impact on Containment Purge?

Containment Purge will _ _ _ _ __

A. automatically isolate with no time delay.

B. automatically isolate after a short time delay.

C. be unaffected and will require manual isolation.

D. be unaffected and will NOT require manual isolation.

Answer: A KplanationlJustification:

A. Correct. The candidate must have knowledge of the impact of a radiation monitor upscale failure high. Specifically, if 2 HVR*RQ1 048 fails high. it will cause an automatic isolation of containment purge. This is the only radiation monitor which has any automatic functions associated with fuel handling. Also note that there is no actual high radiation condition, rather an IF condition exists. The stem of the question states that Containment Purge is in operation and no auto functions have been defeated. This is to alleviate any confusion based on procedure flexibility which allows auto isolation features to be defeated at the end of 20M-44.C.4.A (Containment Purge Startup).

B. Incorrect. Correct that containment purge auto isolates but not after a short time delay. Plausible because some of BVPS radiation monitors have time delays.

C. Incorrect. Plausible if the candidate believes the logic is 2/2 for containment purge to isolate and that manual isolation is required due to impact on fuel handling operations.

D. Incorrect. Plausible if the candidate believes there is no auto isolation and isolation is NOT required which is correct for these plant conditions. (ie:

Which ONE of the following conditions in accordance with Attachment A-0.11 will require the BOP to direct action outside the control room?

A. SWS Pumps seal water pressure LOW.

B. Two Hydrogen Analyzers NOT running.

C. Two Service Water pumps NOT running.

D. All Train "B" orange CIA marks are LIT. (several Train "A" CIA marks are NOT LIT)

Answer: A Explanation/Justification:

A. Correct. The candidate must be able to coordinate personnel activities outside the control room. In order to direct these actions they must be aware of conditions which require local action. The competent RO must be able to verify automatic actions following safety injection lAW Attachment A-O.11 and be able to coordinate local actions in the event that automatic actions have not occurred. Of all of the conditions provided, a SWS pump low seal water pressure condition requires the BOP to dispatch an NLO to the intake structure to investigate this plant condition.

13. Incorrect. Although Attachment A-O.11 does check two hydrogen analyzers running. the required action is to start the analyzers performed in the control room as opposed to outside the control room.

C. Incorrect. Although Attachment A-O.11 does check two service water pumps running, the required actions for this condition are all performed in the control room as opposed to outside the control room.

D. Incorrect. No action is required outside the control room for this condition. As long as all of the valves are closed in one train the redundant train valves do not need to be locally closed.

D. Placing the deborating demineralizer in operation lAW 20M-7.4AM, "Mixed Bed/Deborating Demineralizer Operation".

Answer: C Explanation/Justification:

A. Incorrect. This is a plausible evolution which is a radiation hazard and requires RP assistance due to the potential for high radioactive gaseous release. This hazard is in the PAS as opposed to the safeguards area. This evolution has a potential to result in EPP initiation.

B. Incorrect. LHSI Pumps are located in Safeguards and this evolution recirculates the RWST through the safeguards which makes this distractor plausible. However, this evolution should not increase radiation levels in safeguards.

C. Correct. The candidate must have knowledge of radiation or contamination hazards that may ,lfise during any plant activity. Specifically, they must sort through a list of valid situations and determine that transfer to cold leg recirculation during a LOCA has the greatest potential to increase Safeguards and/or PAS radiation levels. ES-1.3 has a caution that warns the operator of this hazard.

D. Incorrect. This evolution has a potential to increase radiation levels, however, the procedure is more concerned with the potential reactivity event which could occur as a result of this evolution. Increased radiation levels would be more of a concern in the PAS as opposed to Safeguards.

The Embryo/Fetus Dose Equivalent (EFDE) Limit for a Declared Pregnant Worker over the entire gestation period is _ (1)_.

The Site Administrative Control Level Dose Limit (TEDE) for an individual working at the BVPS Nuclear Facility is (2) _ .

A. (1) 100 mr/term (2) 2000 mr/year B. (1) 500 mr/term (2) 1000 mr/year C. (1) 100 mr/term (2) 1000 mr/year D. (1) 500 mr/term (2) 2000 mr/year Answer: B Explanation/Justification:

Incorrect Incorrect but plausible DPW limit. The DPW is limited to 100 mr/month but may havE~ up to 500 mr for the entire term or gestation period. The Annual Administrative Limit for an individual working at a nuclear facility is incorrect because it reflects a BVPS Administrative Limit where extensions are involved. The stem of the question specifically excludes extensions or planned special exposures.

B. Correct. According to NOP-OP-4201 Attachment B, when a worker declares pregnancy, she will have an administrative level of 500 mr for the term of pregnancy. This ensures the dose to the unborn child is minimized. The federal limit is also 500 mrem for the pregnancy period or term.

NOP-OP-4101 refers the reader to NOP-OP-4202 which defines a declared pregnant worker a:nd specifies the occupational dose limit for the entire period of declared pregnancy is 500 mrem (100 mrem/month) NOP-OP-4101 states on ,l\Uachment A that BVPS Administrative Control Limit for TEDE is 1000 mr/year.

C. Incorrect Incorrect DPW value but plausible as described above. Correct BVPS Administrative Control Limit for TEDE.

D. Incorrect Correct value for DPW. Incorrect value for BVPS Administrative Control Limit for TEDE, however plausible because it reflects the initial annual ACL limit for TEDE when dealing with extensions.

A. allowed.

B. NOT allowed at this time.

C. NOT allowed until first transition.

D. allowed by obtaining US/SM concurrence during IOAs.

Answer: B Explanation/Justification:

A. Incorrect. Refer to correct answer explanation. Plausible if the candidate does not know his role in performing pre-emptive actions.

B. Correct. The RO must know his roles and responsibilities during EOP usage. The candidate must know that opening 2CCS-AOV118 is an allowable pre-emptive action. This action should not be performed during lOA's and shall not be performed with out SM/US concurrence. Since the crew is performing Step 4 of E-O, lOA's have not been completed.

Incorrect. Refer to correct answer explanation. Plausible if the candidate confuses rules of usage for FRP implementation.

&,). Incorrect. The SRO may not provide concurrence during lOA's. IOAs are not complete until read and verified.

  • The SM directs the RO to perform actions of 20M-56C.4.C, "NCO Procedure".

Which ONE of the following will be a time critical action performed by the Reactor Operator (RO) outside the Control Room AND reason why?

In accordance with 20M-56C.4.C, the RO will _ _ _ __

A. open [2RCS*PCV456], "PRZR PORV" to reduce RCS pressure.

B. trip [2FWE*P23B], "B" AFW Pump" to prevent Steam Generator overfill.

C. start [2QSS*P2'1 B], "Quench Spray Pump" to reduce containment pressure.

D. close [2CHS*HCV186], "RCP Seal Hdr Flow Control Valve" to protect RCP seals.

Answer: B Explanation/Justification:

A. Incorrect. This is an action performed but is not time critical. There is a time critical action related to closing the PORV if it spuriously opens. This action is performed to preclude the PORV from spuriously lifting and is directed in the US proc:edure vs. RO procedure. The RO actually is directed to take power off PORV 456 isolation valve 2RCS*MOV536.

3. Correct. The candidate must have knowledge of RO actions performed outside the control room during alternate safe shutdown and understand the operational effect of this task. According to 20M-56.C.4.C, pg. 5, it is time critical that the RO secure 2FWE*P23B within 40 minutes to prevent S/G overfill.

C. Incorrect. There is a time critical action for the RO to secure 20SS*P21 B if it spuriously starts but there is no action to start this pump. Plausible if the candidate is unfamiliar with the procedure or has concepts confused.

D. Incorrect. There is a time critical action performed by the NLO versus RO to fail open 2CHS*HCV186 versus close this valve. Plausible incorrect action based on similar actions to isolate RCP seals to prevent action such as ECA-O.O.

  • Tavg is 562 OF and slowly dropping.
  • RCS Pressure is 2230 psig and slowly dropping.
  • A4-8G, Rod Position Deviation is in alarm.
  • Reactor power has dropped to 51 % and is slowly rising.
  • Control Bank D Demand step counters remain at 190 steps.
  • DRPI indication for Rod D4 is ZERO steps.

Based on these conditions:

What procedure contains the REQUIRED guidance to address these plant conditions?

A. E-O, Reactor Trip Or Safety Injection.

B. AOP 2.1.7, Rod Position Indication Malfunction.

C. AOP 2.2.1 C, Power Range Channel Malfunction.

D. AOP 2.1.8, Rod Inoperability.

Answer: D Explanation/Justification:

A. Incorrect. The PR rate coincidence is 2/4 and only one rate bistable has been actuated. Power is above P-9 (50%) however since there is only one rate channel above the trip setpoint. No reactor trip should occur and E-O entry is not required.

B. Incorrect. At BVPS this procedure may be entered as part of the initial diagnostics, however entry into this procedure is not REQUIRED and the procedure will NOT contain the necessary guidance to address the dropped rod situation posed in the question. Additionally, the symptoms section of this procedure address no corresponding power change. In the stem of the question, power has changed. The question specifically asks for the procedure that contains the recovery guidance and NOT what procedure entry is required. The phrasing of the question makes this choice clearly incorrect.

C. Incorrect. With power dropping and temp dropping and power recovering there MUST be some negative p being added (dropped rod). The PR indications are therefore consistent with this negative p addition and they are not malfunctioning.

D. Correct. lAW AOP 2.1.8 symptoms the alarms and plant response are conSistent with a dropped rod. In order to properly diagnosis the dropped rod, the SRO must use the excore response along with the loop Tavg response to conclude that there is in fact a dropped rod and this is not than a DRPI malfunction, or a NIS malfunction, and NO trip setpoint has been exceeded. AOP 2.1.8 addresses a dropped rod in Part A SRO candidate must evaluate the given conditions and those that are NOT present to determine that a rod has dropped, and is in fact at zero steps.

SRO Only in that the SRO must assess plant conditions and then select a procedure to mitigClte, recover, or with which to proceed. This is more than just entry conditions for an AOP which would be RO knowledge. This requires the SRO to have specific knowledge of the procedure content.

Based on these conditions, and lAW the guidance in AOP 2.6.4, how will charging flow and RCS pressure be controlled to minimize RCS-to-Secondary leakage and prevent SG overfill that would lead to water entering the steam lines?

A. Lower charging flow and depressurize the RCS.

B. Lower charging flow and equalize RCS and 21A SG pressures.

C. Raise charging flow and depressurize the RCS.

D. Raise charging 'flow and equalize RCS and 21 A SG pressures.

Answer: C Explanation/Justification:

A. Incorrect. These are the actions from AOP 2.6.4 step 17 if PRZR level is between 50% and 713 % and SG level is rising.

B. Incorrect. Lowering charging flow would allow RCS pressure to drop which would "backfill" water from the ruptured SG and raise PRZR level.

89. Given the following conditions:
  • The plant is at 100% power with all systems in NSA.
  • The RO (ATC) has recently performed a small dilution for Tavg control.

Shortly after the dilution, the following conditions exist:

  • Power Range NI's are increasing.
  • Tavg is decreasing.
  • Steam flow and feed flow are slightly elevated.
  • Reactor power is 101 % and rising slowly.

Which ONE of the following describes the event in progress and the action required?

A. Main steam line leak; reduce power to less than 100% by reducing turbine load as necessary.

B. Inadvertent Res dilution; reduce power to less than 100% by adjusting control rods.

C. Main steam line leak; trip the reactor and enter E-O, Reactor Trip Or Safety Injection.

D. Inadvertent RCS dilution; trip the reactor and enter E-O, Reactor Trip Or Safety Injection.

Answer: A Explanation/Justification:

A. Correct. Conditions in the stem indicate a steam break. lAW AOP 2.51.2 step 2 RNO. Diagnosis of the event is RO knowledge. Selecting the appropriate procedure and directing the appropriate actions is SRO only knowledge. SRO must evaluate plant conditions and determine appropriate procedural action. in this case power must be brought below 100% and step 2 of the AOP is a continuous action step for the SRO to direct the crew to reduce turbine load as necessary and at rate determined by the SRO.

B. Incorrect. Candidate may believe that something about the recent dilution has caused these conditions. The dilution will cause power to rise initially until the MTC feedback offsets the effects. This does not explain why Tavg is dropping and steam/feed are rising. Reducing power is the correct action. but not by rod movement.

C. Incorrect. Conditions in the stem indicate a steam break. AOP 2.51. 2 does not direct a reactclr trip. If the steam break indications were more severe, then a trip would be warranted based on approaching the high flux trip setpoint.

D. Incorrect. Candidate may believe that something about the recent dilution has caused these conditions. The dilution will cause power to rise initially until the MTC feedback offsets the effects. This does not explain why Tavg is dropping and steam/feed are rising. AOP 2.51. 2 does not direct a reactor trip.

Answer: C Explanation/Justification:

A. Incorrect. This would be the required action if the candidate believes that having two steam supply lines unavailable constitutes two inoperable trains of AFW.

B. Incorrect. This would be the required action if the candidate believes that having two steam supply lines unavailable constitutes an inoperable steam driven AFW pump. The requirement to re-align the supply headers is already being met by the NSA alignment.

C. Correct. lAW T. S. 3.7.S and bases ONLY two of three steam supply lines are required for steam driven AFW pump operability. The candidate will need to use the TS bases to recognize that ONLY two of three steam supply lines are required for steam driven AFW pump operability. The Condition A statement specifically says one of the required steam supply lines inoperable. Therefore, taking 2MSS*SOV10SA out of service would not require any TS action since 2 trains are still available. When 2MSS*SOV10SE fails to meet the required stroke time, it must be declared inoperable and Condo A action would apply. It is an SRO responsibility to be familiar enough with the operability requirements for the SOV to declare it inoperable based on the performance data presented in the stem. BRO only because it requires Application of Required Actions in Section 3 of the TS, which is an SRO responsibility.

D. Incorrect. This would be the required action if the candidate believes that the 10 day statement in Condo A provides an additional allowance for two inoperable steam supplies. The bases for this 10 day statement is to limit the time allowed in thi condition when Condo A and B are entered concurrently.

93. The Plant is operating at 100% power with all systems in NSA.
  • After the automatic FAST bus transfer, SSST 2A experiences an under frequency condition, which causes 4Kv busses 2A and 2B to de-energize.
  • All other systems function as designed.

The crew enters E-O, Reactor Trip or Safety Injection and has just completed the Immediate Operator Actions.

Safety Injection has not actuated and is not required.

Current plant conditions are as follows:

  • RCS pressure is 2100 pSig and slowly riSing.
  • S/G pressures are 1000 psig and stable.
  • Tavg is 550 OF and slowly rising
  • Tcold is 542 OF in all three loops and stable.
  • NR S/G levels are 10% and rising.

3. Place the Steam Dump Control in Steam Pressure Mode C. Throttle total AFW flow to greater than or equal to 300 gpm D. Place the Low Steamline Pressure SI block switches to block Answer: B Explanation/Justification:

A. Incorrect. Manually actuating SLI will physically prevent SI. However, there is NO EOP procedural guidance to perform this action.

B. Correct. lAW 1I20M-53B.2 Iss 1C Rev. 7 page 7 preemptive action guidelines. The SM!US should direct this action to avoid the SI. SRO only since the SRO must assess plant conditions and then selecting a section of a procedure to mitigate, recover, or with which to proceed. In this case the SRO must recognize that the setting up of natural circulation with the steam dumps in Tavg mode will result in an inappropriate Sf. The SRO must further recognize that an EOP preemptive action exists for this situation, and direct the crew to place the steam dumps in the steam pressure. Mode.

C. Incorrect. Throttling AFW flow is also a preemptive action. However, this is only required to control a cooldown and no cooldown exists.

Additionally, throttling AFW flow will not prevent the SI for these conditions.

D. Incorrect. This would prevent the SI if RCS pressure was below 2000 psig. Since RCS pressure is above 2000 psig SI will not be blocked.

99. The Plant is operating at 100% power with all systems in NSA.
  • A loss of all 4KV AC power occurs
  • The crew enters ECA-O.O, Loss of All AC Power After 30 minutes, power is restored to one 4KV Emergency bus and the crew has reached the end of procedure ECA-O.O and are in the process of selecting the appropriate recovery procedure. The following conditions now exist:
  • RCS subcooling is ZERO degrees
  • PRZR level is 2% and dropping
  • HHSI and LHSI flows are ZERO gpm
  • A RED path condition exists for the heat sink status tree Based on these conditions, what procedure transition is required?

Transition to _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ __

A. FR-H.1, Response To Loss Of Secondary Heat Sink B. ECA-0.1, Loss of All AC Power Recovery Without SI Required C. ECA-0.2, Loss of All AC Power Recovery With SI Required D. ES -0.2, Natural Circulation Cooldown

'nswer: C Explanation/Justification:

A. Incorrect. FRPs usuaUy have higher priority than ECA procedure. In tis case they do not since I:::CA-0.1 and 0.2 are structured such that they will restart E5F equipment. Only after completing these steps will FR-H.1 be implemented.

B. Incorrect. The conditions in the stem indicate the need for 51.

C. Correct. lAW the NOTE prior to step 1 of ECA-O.O FRPs are not to be implemented while in ECA-O.O. A note prior to step 1 of both ECA-0.1 and 0.2 then reminds the operator to complete steps 1-11 before implementing any FRP. Therefore, the appropriate transition is to ECA-0.2 since the conditions in the stem indicate the need for 51. 5RO only since it requires the additional knowledge of the procedure's content and; assessing plant conditions and then selecting a procedure to mitigate, recover, or with which to proceed.

D. Incorrect. Without any normal 4KV power, the RCP will not be running and this would be a transition if 4KV emergrncy had not been lost.

Beaver Valley Unit 2 NRC Written Exam (2LOT8) 100. Given th~ following plant conditions:

  • Unit 2 core off-load is in progress.
  • The Control Room receives a report that cable separation has occurred on the upender containing an irradiated fuel assembly from the vertical position.
  • The RO reports that [2RMF-RQ301A1Bl, "Fuel Building Vent radiation levels are rising and High alarms are validated.
  • The Control Room has received A4-5A, "Radiation Monitoring System Trouble" AND A4-5C, "Radiation Monitoring Level High".
  • No other alarms are present.

Have entry conditions been met for the SRO to perform AOP 2.49.1, "Irradiated Fuel Damage" actions AND using the Emergency Plan Procedure provided, does an ALERT classification exist for the present plant conditions? (Excluding ED Judgment)

AOP 2.49.1 entry conditions _ _ (1) _ _ been met.

An ALERT classification _ _ (2) __ exist for the stated plant conditions.

(Refer to attached reference)

A (1) have (2) does

8. (1) have NOT (2) does C. (1) have (2) does NOT D. (1) have NOT (2) does NOT Answer: A Explanation/Justification:

A. Correct. lAW AOP 2.49.1 entry conditions and EPP Tab 6.5. SRO only since it requires classification in the EPP.

B. Incorrect. AOP entry conditions do exist if 2RMF-RQ301A1B are in high alarm. It is correct that an Alert classification exists.

C. Incorrect. Correct that AOP entry conditions are met. However, an Alert classification exists in Tab 6.5.

D. Incorrect. AOP entry conditions do exist if 2RMF-RQ301AIB are in high alarm. Entry conditions would not exist if they were only at the alert level.

An Alert classification exists in Tab 6.5.
