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.Question Level:

Source:BankDistractor 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.Question Level:

Source:BankDistractor 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:

HQuestion Difficulty 3Justification: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).RO Importance:

Source:BankDistractor 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:

HQuestion Difficulty 3Justification: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.RO Importance:

Source:BankDistractor 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.

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:BankDistractor 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).

Source:NewDistractor Justification A:INCORRECT: 2210 psig is plausible because it is a pressure associated with the Pressurizer pressure control systems (the pressure at which backup heaters will turn on).

B:INCORRECT: If PT-456 reached 2335 psig, a PORV would open and pressure would lower but that is not the case here. 2210 psig is plausible because it is a pressure associated with the Pressurizer pressure control systems (the pressure at which backup heaters will turn on).

C:CORRECT: The first channel listed on the selector switch is the controlling channel and therefore the one that needs to fail to cause pressure to lower. In this case just the Spray Valves would be open causing PZR pressure to lower. (actual pressure will also lower if the second channel reaches the PORV setpoint of 2335 psig).

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.

D:INCORRECT: This distractor is credible because the pump bearings are cooled and lubricated by the flow of water coming up through the pump casing and a partially closed discharge valve will reduce this flow but not enough to effect the temperature of the pump bearings.Question Level:

(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.

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.

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.

However, only RHR Pumps 1A and 1B provide letdown. If this pump was supplying cooling, then IAW the POP09, the RHR procedure would be the correct entry.

B:CORRECT: If this pump was supplying cooling, then IAW the POP09, the RHR procedure would be the correct entry.

However, only RHR Pumps 1A and 1B provide letdown.D:CORRECT: During solid plant conditions the RHR pump being used for letdown will not be used for cooling. In this case RHR pump 1A is the only one that can be used for letdown so RHR 1C is used for cooling. When 1A RHR pump trips then letdown flow lowers and RCS pressure INITIALLY rises (charging flow is in manual) until corrected by PCV-0135 adjusting more open to lower pressure.

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.
