Source: Bank Modified from Distractor Justification A: INCORRECT: Plausible because this is the speed for a temperature error <1 °F, so the student must accurately determine what actual tamperature is.

B: CORRECT - At 92% power, programmed Tavg is 590 °F. Tavg is 1 °F low, so Tavg is 589 °F. A high failure of PT-505 will cause Tref to go to the high limit of 592 °F. This will result in a 3 °F mismatch between Tavg and Tref. Rod speed for this mismatch is 6 spm.

C: INCORRECT: Plausible because this is the speed for a temperature error of 4 °F, so the student must accurately determine what actual tamperature is.

D: INCORRECT: Plausible because this is the speed for a temperature error of 5 °F, so the student must accurately determine what actual tamperature is.

B: INCORRECT: Plausible because an air operated valve can fail either open or closed and its location in the system will determine its effect (which could be raise or lower temperature). RHR Hx Bypass Valves DO fail closed on loss of air, but that would result in RCS temperature lowering, not rising.

C: CORRECT: The RHR Hx Outlet Temp Cont Valves fail open and the Bypass Flow Cont valves fail closed on a loss of IA. Either of these failures will cause RCS temperature to lower because there is greater heat removal in the RHR Hx.

Source: Bank Modified from Distractor Justification A: INCORRECT: This is a credible distractor because if the battery output breaker trips it will cause the given alarm but with the voltage and amperage given are not indicative of an open battery output breaker. If the Battery output breaker opens there would be no charging or discharging current and 125 VDC bus volts would be normal (130 vdc).

B: INCORRECT: This distractor is credible because the system has two battery chargers but the standby charger is normally not in service and will not automatically connect to the bus.

C: CORRECT: The inservice battery charger normally supplies dc bus loads and keeps the battery charged. If the battery charger trips, the battery supplies bus loads and the battery output current meter shows the discharge condition (minus amps) relative to the charging condition. Additionally, the bus (battery) voltage will be lower than normal due to the battery now supplying loads.

D: INCORRECT: This distractor is credible because the Inverter/Rectifier associated with 125 VDC Bus E2D11 is a load to the Battery and Charger but a loss of this load will not change 125 VDC Bus E2D11, only reduce the amount of current required from the Battery/Battery Charger.

Source: Bank Modified from Distractor Justification A: INCORRECT: This distractor is credible because there was a significant leak as stated, but the leak is in the SAS, not the IAS, as evidenced by IAS pressure recovering after the SAS Isolation Valve closed.

B: CORRECT: The leak is significant because at the given air pressures, all air compressers would be operating yet pressure continues to lower. The leak has been isolated by closure of the Service Air Isolation Valve because service air pressure continues to lower while Instrument air pressure begins to rise.

C: INCORRECT: This distractor is credible because the leak is significant because at the given air pressures, all air compressers would be operating yet pressure continues to lower. Additionally, the leak was in the SAS, not the IAS, and was isolated by the SAS Isolation Valve, not the IA to Yard Isolation Valve because air pressure did not get low enough for the IA to Yard valve to close.

D: INCORRECT: This distractor is credible because the leak is significant because at the given air pressures, all air compressers would be operating yet pressure continues to lower. The leak was in the SAS as stated, but was isolated by the SAS Isolation Valve, not the IA to Yard Isolation Valve because air pressure did not get low enough for the IA to Yard valve to close.

Question Level: H Question Difficulty 3 Justification:

Candidate must analyze the change in IAS/SAS header pressures and combine with the knowledge that SAS Isolation Valve automatically closes at 100 psig and all four air compressors are running at 113 psig IA pressure. Since it was given that all systems operate as designed, the SAS Isolation Valve closed at 100 psig (indicated by an decreasing SAS header pressure and increasing IAS header pressure) and successfully isolated the SAS. SA header pressure is decreasing at a significant rate thus the leak is significant (not minor).

Source: Bank Modified from Distractor Justification A: INCORRECT - This distractor is credible because the voltage being less than XFMR voltage is opposite of being slightly greater than XFMR voltage when the ESF DG is being parralled to a BUS energized from offsite power.

B: CORRECT - The synchroscope should be in the slow direction so the DG will lose some load and the voltages should be matched to minimize reactive load changes.

C: INCORRECT - This distractor is credible because the synchroscope direction (FAST direction) is correct when the ESF DG is being parralled to a BUS energized from offsite power. Also, the voltage being less than XFMR voltage is opposite of being slightly greater than XFMR voltage when the ESF DG is being parralled to a BUS energized from offsite power.

D: INCORRECT - This distractor is credible because the synchroscope direction (FAST direction) is correct when the ESF DG is being parralled to a BUS energized from offsite power.

Question Level: H Question Difficulty 3 Justification:

The applicant must understand that the conditions given do not represent the "normal" paralleling operation (paralleling the DG with offsite power). Since the DG is being paralleled in the opposite direction, the applicant must determine that the synchroscope must rotate in the opposite (slow) direction. Since the reactive loading of the DG is unknown, the applicant should realize that matching voltages is necessary to minimize reactive loading changes on the DG when the normal supply breaker is closed.

Source: Bank Modified from Distractor Justification A: INCORRECT: Downstream temperature of a Pzr PORV would be much lower. Distractor is plausible if the student believed the downstream temperature is the same as the upstream temperature (common misconception) since 629° is the saturation temperature for 1885 psig.

B: INCORRECT: Downstream temperature of a Pzr Safety would be much lower. Distractor is plausible if the student believed the tailpipe temperature rose to 653° (normal Pzr temp) after the PORV opened (same misconception as above) and is now cooling down because the valve reseated.

C: INCORRECT: Tailpipe temperature is too low for an open/throttled PORV under these conditions.

Distractor is plausible is the student understood that the tailpipe temperature would be less than PZR temperature but misuses the Mollier diagram or steam tables (240° is ~saturation temperature for 25 psig)

D: CORRECT - Based on the throttling process, the tailpipe temperature for this condition would be 267 degrees if the valve were open. With the tailpipe at this temperature, it would mean the valve is now closed and the tailpipe is cooling off.

Source: Bank Modified from Distractor Justification A: INCORRECT: This distractor is credible because lowering RCS pressure, and thereby temperature, can result in an Auto MSL isolation but lowering RCS pressure to 1850 would result in an SI but it would not be enough to cause an Auto MSL isolation.

B: CORRECT: This condition will result in steamline pressure being less than 735 psig (about 665psig) with Low Steamline Pressure SI still enabled (RCS pressure is greater than P-11, 1985psig), which will result in an Auto SI and MSL isolation.

C: INCORRECT: This distractor is credible because at this temperature, raising pressure above the P-11 setpoint of 1985 psig would result in an Auto MSL isolation, but only raising pressure to 1950 psig will not reach the P-11 setpoint thus no Auto MSL isolation will occur.

Source: Bank Modified from Distractor Justification A: INCORRECT: This distractor is credible because the stem of the question says the PZR Pressure channel failed high but it takes 2 channels failing high to cause a PZR Pressure high pressure trip.

B: INCORRECT: This distractor is credible because the Pressurizer PORV Interlock (Block) will close PORV 655A (which opened when PT-457 failed high). But this interlock does not have any affect on the Pressurizer Spray Valve(s) operation. The Spray Valves are controlled from the Pressurizer Pressure Master Controller.

C: CORRECT: Pressuirzer Pressure will decrease due to a full open signal for the Pressurizer Spray Valves and an open command for Pressuirzer PORV 655A, both due to the high failure of PT-457.

At 2185 psig PORV 655A will close due to PT-458 blocking closed PORV 655A. However, with out operator action the Master Controller is still having a high input from the failed high PT-457 and full spray flow is still occuring causing Pressurizer Pressure to continue to decrease. The reactor will trip on low Pressurizer Pressure of 1870 psig from 2 of 3 channels that are not failed, PT-455, PT-456, and PT-458, D: INCORRECT: This distractor is credible because the Pressurizer PORV Interlock (Block) will close PORV 655A (which opened when PT-457 failed high). But this interlock does not have any affect on the Pressurizer Backup Heater operation. The Backup Heaters are controlled from the Pressurizer Pressure Master Controller.

Source: Bank Modified from Distractor Justification A: INCORRECT: This distractor is credible because raising the potentiomenter setting on PK-0557 will raise the setpoint and steam pressure will then be controlled at a higher pressure. This will raise the saturation temperature inside the steam generator. This higher temperature will then cause RCS temperature to increase. With an RCS temperature increase and a negative MTC, this will cause negative reactivity to be inserted and reactor power will decrease. Therefore Tavg would not remain the same and power would not increase.

B: INCORRECT: This distractor is credible because raising the potentiomenter setting on PK-0557 will raise the setpoint and steam pressure will then be controlled at a higher pressure. This will raise the saturation temperature inside the steam generator. This higher temperature will then cause RCS temperature to increase. With an RCS temperature increase and a negative MTC, this will cause negative reactivity to be inserted and reactor power will decrease. Therefore Tavg would not remain the same. However with the potentiometer change, reactor power would decrease.

C: CORRECT: Raising the potentiomenter setting on PK-0557 will raise the setpoint and steam pressure will then be controlled at a higher pressure. This will raise the saturation temperature inside the steam generator. This higher temperature will then cause RCS temperature to increase.

With an RCS temperature increase and a negative MTC, this will cause negative reactivity to be inserted and reactor power will decrease.

D: INCORRECT: This distractor is credible because raising the potentiomenter setting on PK-0557 will raise the setpoint and steam pressure will then be controlled at a higher pressure. This will raise the saturation temperature inside the steam generator. This higher temperature will then cause RCS temperature to increase. With an RCS temperature increase and a negative MTC, this will cause negative reactivity to be inserted and reactor power will decrease. Therefore raising the potentiometer setting does not cause steam pressure to decrease, causing RCS temperature to decrease and add positive reactivity for a reactor power increase.

If seal injection flow were 5 gpm then a seal injecton flow low alarm would annunciate.

B: CORRECT: The design seal injection flow from CVCS to the RCP seal is 8 gpm and the thermal barrier heat exchanger acts as a backup in the event of a loss of seal injection flow by cooling the water from the RCS that would be flowing in reverse direction through the thermal barrier and into the seal package.

Source: New Modified from Distractor Justification A: INCORRECT: This distractor is credible because if an SI actuation was present then SI will block the trip of an ECW pump from discharge valve position even though a partial loss of the system flow may occur. The cooler is supplied by ECW to protect the CCW pump motor.

B: CORRECT: The ECW pumps do not have a recirc line dedicated for low flow conditions and therefore the logic to trip the pump is built in if the discharge valve does not open fully (95%) within 25 seconds unless an SI is present.

C: INCORRECT: This distractor is credible because if an SI actuation was present then SI will block the trip of an ECW pump from discharge valve position even though a partial loss of the system flow may occur. The RCFCs are cooled by RCB chilled water normally, but RCB chilled water is isolated during a LOOP and also, the RCB Chiller condenser is cooled by OL-ACW not ECW.

Source: Bank Modified From Distractor Justification A: CORRECT: Accurate per TS 3.9.10 bases B: INCORRECT: Plausible because at first it seems logical that a large volume of borated water above the core would hinder a dilution, however the water in the RCS doe not mix with the water above the vessel in the cavity, so it does not matter in that regard.,

C: INCORRECT: Plausible because TS requires an RHR pump to be in operation with 3000 gpm of flow which required a minimum amount of head to prevent cavitiation.

D: INCORRECT: Plausible because during fuel movement, the RCS and SFP are tied together and level is controlled based on the cavity. A certain height of water in the cavity corresponds to a certain height of water in the SFP which provides NPSH for the SFP Pumps.

Source: New Modified From Distractor Justification A: CORRECT: With the given conditions the Fission Product Barrier Degradation totals 8 points. 3 points for potential loss of fuel clad due to Core Cooling Orange Path or RCS Plenum level at 20%

or CETs at 715 degrees F. 4 points for loss of RCS due to Core Cooling Yellow with subcooling less than 0 degrees F. (Core Cooling Orange and CETs at 715 degrees F would satisfy this) 1 point for potential loss of Containment due to Core Cooling Orange greater than 15 minutes. With RCS DEI at 350 uCi/gm fuel clad would go from potential loss to loss. (3 points to 4 points) This would make the Fission Product Barrier total 9 points and thus raise the E-Plan declaration to a General Emergency.

B: INCORRECT: This is a credible distractor because although the failed fuel monitor reading of 900uCi/ml is greater than the limit of 870uCi/ml this represents on a potential loss of the fuel clad which has already been identified.

C: INCORRECT: This is a credible distractor because athough Containment pressure of 25 psig is considerably high, Containment pressure alone could not cause an escalation to a GE because it would only represent a potential loss of Containment which has already been identified.

D: INCORRECT: This is a credible distractor because although an elevated reading on the Containment Hatch Rad Monitor could cause an escalation in the E-Plan classification the reading would have to go above 222mR/hr.

Source: Bank Modified From Distractor Justification A: CORRECT: Low flow in any RCS loop should initiate a reactor trip if above P8. This is an ATWS event, but the FIRST procedure to be entered should be 0POP05-EO-EO00, Reactor Trip or Safety Injection.

B: INCORRECT: This distractor is credible because Low flow in any RCS loop should initiate a reactor trip if above P8. However, this is an ATWS event, but the first EOP to be entered should be 0POP05-EO-EO00, Reactor Trip or Safety Injection, not 0POP05-EO-FRS1, Response to Nuclear Power Generation - ATWS. 0POP05-EO-FRS1, Response to Nuclear Power Generation - ATWS, would be entered only after the reactor could not be tripped automatically or manually from the control room.

C: INCORRECT: This distractor is credible because low flow in one RCS loop will not cause a reactor trip if the Unit is below the P-8 setpoint (40%). At 48% power the reactor is below the P-9 setpoint which does not trip the reactor if the main turbine trips. Entering 0POP04-RC-0002, Reactor Coolant Pump Off Normal, FIRST would be credible if the reactor had not tripped. This procedure is an off-normal procedure.

D: INCORRECT: This distractor is credible because low flow in one RCS loop will not cause a reactor trip if the Unit is below the P-8 setpoint (40%). At 48% power the reactor is below the P-9 setpoint which does not trip the reactor if the main turbine trips. Entering 0POP09-AN-05M2, A-1, LOOP FLOW LO RX PRETRP, FIRST would be credible if the reactor had not tripped. This annunciator is a yellow annunciator.

instead of PZR level.Also, if the student believes that Core Cooling is inadequate then a transition to SACRG-1, SEVERE ACCIDENT CONTROL ROOM GUIDELINE INITIAL RESPONSE, is credible because there is a transition from 0POP05-EO-FRC1.

B: INCORRECT: This distractor is credible because even though RVWL level is low it is OK for transition ing out of 0POP05-EO-FRC1. FRC1 allows for RVWL level to be used (greater than 20%)

instead of PZR level. Also, if the student believes that Core Cooling is still inadequate but getting better (Critical Safety Function has changed from Red to an Orange Path), then it would be credible to believe a transition to 0POP05-EO-FRC2, RESPONSE TO DEGRADED CORE COOLING, would be next.

C: CORRECT: RVWL plenum level of greater than 20% is allowed to be used to transition out of 0POP05-EO-FRC1, RESPONSE TO INADEQUATE CORE COOLING. The correct procedure transition is 0POP05-EO-EO10, LOSS OF REACTOR OR SECONDARY COOLANT.

B: INCORRECT: Validation method is plausible because dilution is generally the first cause that comes to mind in a situation such as this, however the source of the reactivity increase could be from elsewhere that the RCS sample would not detect and the sample is time consuming.

C: INCORRECT: Action is plausible because it is also contained in the annunciator response (and could stop a dilution event), but it is the action you take if a shutdown monitor is inoperable.

D: INCORRECT: Validation method is plausible because dilution is generally the first cause that comes to mind in a situation such as this, however the source of the reactivity increase could be from elsewhere that the RCS sample would not detect and the sample is time consuming.
