2 RO Sort:

Question:

Given the following:

• The reactor has tripped and safety injection has actuated.

• The RCS has a stuck open Pressurizer Safety valve.

• The RCS has rapidly depressurized to saturation conditions.

• Pressurizer level initially dropped and then began to rise rapidly.

Which one (1) of the following characterizes the relationship between indicated pressurizer level and RCS inventory and the reason for these conditions?

A. Level is NOT an accurate indication of inventory. The cold calibrated pressurizer level channels indicate high during high temperature, low pressure conditions.

B. Level is an accurate indication of inventory. Voiding would occur first in the pressurizer steam space due to the higher temperature of the pressurizer walls.

C. Level is NOT an accurate indication of inventory. Reactor vessel voiding may result in a rapidly rising pressurizer level.

D. Level is an accurate indication of inventory. RCP flow would sweep any voids from the RCS to the pressurizer steam space and out the safety.

Answer:

C. Level is NOT an accurate indication of inventory. Reactor vessel voiding may result in a rapidly rising pressurizer level.

Notes:

"A" is true but it's contribution to a false level is not significant in this event. "B" & "D" are both incorrect.

• 'A' and 'D' reactor coolant pumps are running

• The upper limit for RCS pressure is 280 psia

• The lower limit for RCS pressure is 260 psia The upper RCS pressure limit is based on ________________ and the lower RCS pressure limit is based on A. automatic closure of SDC suction isolation valves to prevent overpressure in SDC piping; loss of Reactor Coolant pump NPSH B. automatic closure of SDC suction isolation valves to prevent overpressure in SDC piping; loss of Low Pressure Safety Injection pump NPSH C. lifting the SDC suction thermal relief valve to prevent a loss of RCS inventory; loss of Reactor Coolant pump NPSH D. lifting the SDC suction thermal relief valve to prevent a loss of RCS inventory; loss of Low Pressure Safety Injection pump NPSH Answer:

A. automatic closure of SDC suction isolation valves to prevent overpressure in SDC piping; loss of Reactor Coolant pump NPSH Notes:

The limit of 280 psia includes instrument inaccuracies to prevent going above 300 psia which is the SDC suction valve closure setpoint. This closure would cause a loss of SDC.

Two SDC thermal relief's are installed in the SDC suction line that lift at 2485 psig and 440 psig respectively due to thermal expansion should the SDC suctions go closed thus distracters C and D are incorrect.

To prevent pressurized thermal shock from causing brittle fracture of the Reactor Vessel, RCS pressure should be reduced below _________ psia using ________ spray.

A. 1800; Aux B. 1800; Main C. 1540; Aux D. 1175; Main Answer:

C. 1540; Aux Notes:

200 degrees MTS is the License basis that will ensure brittle fracture does not occur after a rapid cooldown.

400°F plus 200°F = 600°F. The saturation pressure for 600°F is 1543.2 psia. All other distracters are higher than the 200°F MTS line of the RCS PT Limits curve in 2202.010 Attachment 1 Also Main spray is not available due to no RCP because they were secured when Containment Spray Actuated in SPTAs.

All of this makes distracters A, B, AND C incorrect.

Question:

Why does OP 2202.006, Loss of Feedwater require the operators to feed the Steam Generators using the EFW system flow at less than 150 gpm for five minutes when S/G narrow range level is less than 49%?

A. To minimize the amount of shrinkage to the steam generator level.

B. To minimize the possibility of water hammer in the emergency feedwater system.

C. To minimize the possibility of damage to the steam generator feed ring.

D. To ensure the most reliable source of feedwater is used to restore steam generator level.

Answer:

C. To minimize the possibility of damage to the steam generator feed ring.

Notes:

Distracter A is incorrect because there will be some shrinkage but its is inconsequential.

Distracter B is incorrect because there may be water hammer if flow is not limited, but damage would occur to main feed line instead of EFW.

Distracter D is incorrect because EFW is the safety system for feed to SGs, and the preferred source in a Loss of all Feedwater, but the procedure also addresses AFW and MFW as feed sources.

Consider the following.

• Unit 2 has tripped due to a LOCA

• Core CET's indicate 610 deg F and rising

• T-hot indicates 605 deg F and rising

• Pressurizer pressure indicates 1200 psia and lowering

• RVLMS Level 7 and below indicates wet

• SG levels are 25% Narrow Range levels each Given these conditions what is the potential for core damage?

A. There is no indication of potential for core damage as long as RCS pressure is maintained less than 2500 psia.

B. There is no indication of potential for core damage as long as negative reactivity is maintained.

C. There is potential for core damage due to inadequate RCS inventory causing superheat.

D. There is potential for core damage due to inadequate Steam Generator inventory Answer:

C. There is potential for core damage due to inadequate RCS inventory causing superheat Notes:

The LOCA EOP, uses TH and CET temperature less than superheated as the limit to ensure that the recovery strategy is effective in core heat removal. The EOP uses additional criteria which allow temperature to be as much as 10°F superheated as long as RVLMS indicates that the core is covered (Level 6 or higher). The EOP contains a final acceptance criteria in the event that temperature is superheated, but by not more than 10°F, and the RVLMS is inoperable. In this case, temperature is required to not be rising and less than 700°F.

Distracter A is not correct because RCS pressure should be lowered to minimize break flow and 2500 psia 45

Questions For 2005 RO and SRO Exam 14-Jan-05 would challenge the rest of the RCS boundary Distracter B is incorrect because negative reactivity does not ensure all decay heat is removed from the core.

Distracter D is incorrect because Steam Generator level greater than 70 inches ensures RCS heat removal due to decay heat.

Given the following:

• A refueling outage has been competed.

• The PZR has been filled to 85% in preparation of forming a steam bubble.

• All PZR heaters have been energized and the temperature of the PZR is rising.

• The PZR is being vented to the Quench Tank to remove non-condensable gases.

• The Quench Tank is being vented and purged when it reaches 30 psig.

Which of the following parameter changes would indicate that all of the non condensable gases have been removed from the Pressurizer.

A. Quench Tank pressure rising continuously with Quench Tank level stable.

B. Pressurizer pressure rising with PZR water temperature below saturation .

C. Quench Tank pressure rising slightly with Quench Tank level rising slightly.

D. Pressurizer pressure lowering with PZR water temperature at saturation .

Answer:

C. Quench Tank pressure rising slightly with Quench Tank level rising slightly.

Notes:

The PZR high point vents enter the QT through the PZR Safety Valve line and are discharged below the water line so when all non-condensable gases are vented from PZR, then QT pressure will rise only slightly. This is due to only steam being vented into QT that is condensed causing level and pressure to rise only slightly.

Distracter A is incorrect because this is what you would expect to see with non-condensable gases being vented to the Quench Tank.

Distracter B is incorrect because the only way PZR pressure could rise below saturation temperature is with non-condensable gases present in the PZR.

Distracter D is incorrect because PZR pressure would remain constant at saturation temperature or rise as 55

Question:

Given the following conditions:

• The plant is at full power when all 4 RCP CCW Low Flow alarms come in.

• An inadvertent CIAS has caused this Loss of CCW to Containment.

What effect, if any, will the above conditions have on the CEA Control Rod Drive Mechanisms (CRDMs) temperatures?

A. No effect on temperature since CCW does not supply cooling to the CRDMs.

B. Temperatures will rise due to the loss of Chilled Water cooling to the CRDMs.

C. No effect since Service Water will automatically supply cooling to the CRDMs.

D. Temperatures will rise due to the loss of CCW cooling supply to the CRDMs.

Answer:

B. Temperatures will rise due to the loss of Chilled Water cooling to the CRDMs.

Notes:

Distracter A is incorrect because while it is true that CCW does not supply cooling to the CRDMs, the CIAS signal also isolates Chill Water to Containment which will cause CRDM temperatures to rise.

Distracter C is incorrect because Service Water can only supply the Containment Fan Coolers not CRDM coolers and will automatically supply them on a CCAS not an CIAS.

Distracter D is incorrect because CCW does not supply the CRDM coolers.

Description:

Knowledge of the effect of a loss or malfunction of the following will have on the PZR PCS: PRT (Pressurizer Relief Tank).

36 RO Sort:

Question:

Given the following:

• The plant was tripped from full power due to a small beak LOCA

• RCS Margin to Saturation went below 30°F and all RCPs were secured.

• Quench Tank (QT) Vent Solenoid Valve From the Reactor Head and PZR 2SV-4669-1 on 2C336-1 has lost power.

• Charging Header to RCP Loop B Isolation 2CV-4827-2 on 2C09 will NOT Close.

• Pressurizer level is 15% and slowly dropping.

• RCS pressure is 1750 psia and slowly rising.

• RCS Margin to Saturation is now reading 55°F and rising.

• Steam Generator levels are 25% NR and steady.

Which of the following actions would be the correct action to take lower RCS pressure to minimize break flow and restore Pressurizer level?

A. Align and throttle Main Spray Valves 2CV-4651 and 2CV-4652 as necessary.

B. Align and throttle Auxiliary Spray Valve from CVCS 2CV-4824-2 as necessary.

C. Align and cycle ECCS Vents Valves 2CV-4740-2 and 2CV-4698-1 to the Quench Tank.

D. Align and cycle PZR Vent Valves 2SV-4636-2 and 2SV-4670-2 to Containment Atmosphere.

Answer:

D. Align and cycle PZR Vent Valves 2SV-4636-2 and 2SV-4670-2 to Containment Atmosphere.

Notes:

The candidate must analyze this situation and realize several things. Main Spray is not available because RCPs are secured. Aux spray will not get to the PZR because the Charging Path to the RCS cannot be isolated thus flow will go to the path of least resistance. ECCS vents would compound the Pressure control problem and are not needed. The Quench Tank is not available as a vent path because Solenoid Vent Valve 2SV-4669-1 has no power. Thus the only available means of pressure control is venting the PZR to the Containment Atmosphere.

Distracter A is incorrect because the RCPs are secured.

Distracter B is incorrect because the flowpath of CVCS would go into the RCS instead of the PZR.

61

Questions For 2005 RO and SRO Exam 14-Jan-05 Distracter C is incorrect because this is too large of a vent path and would cause a massive drop in RCS Pressure.

C. The Main Regulating Valve would Close and the Bypass Regulating Valve would remain Closed.

Notes:

A High Level Override signal is sent directly to the Valve controllers downstream of the master controller at a SG level of 82% to close both the Main and Bypass Feedwater Regulating Valves when their individual controller is in Automatic. The Bypass valve would have been closed prior to the transient should remain this way based on high level override and no input from the Master Controller.

• The plant is at full power with severe weather in the area.

• The plant experienced a complete loss of Green Vital 125 VDC.

• Now a complete loss of offsite power occurs causing a plant trip.

• Both EDGs start and load their respective ESF buses.

• Steam Generator (SG) levels drop to 21% right after the trip.

• All actuation's occur as designed.

How would the EFW system automatically respond to remove heat from the RCS?

D. EFW Pump 2P-7B would start and feed both SG's Notes:

The 2P-7A Steam Driven EFW pump is designed to operate with a complete loss of AC but its supply valve is powered from Green Vital DC along with its closed discharge isolation valves. The Red AC driven 2P-7B is designed to operate with a loss of Green DC due to its discharge valves being Red AC powered. In this case the 2P-7B would auto start and feed both Steam Generators.

Distracter A and C are incorrect because 2P-7A could not start without Green DC Power.

Distracter B is incorrect because the 2P-7B would feed both Steam Generators.

Question:

Which of the following design feature on the Emergency Diesel Generators allows them to be paralleled with offsite AC sources during normal surveillances?

A. The electrical speed governor is operated in the Isochronous speed control mode.

B. The mechanical speed governor is operated in the Isochronous speed control mode.

C. The electrical speed governor is operated in the Droop speed control mode.

D. The mechanical speed governor is operated in the Droop speed control mode.

Answer:

C. The electrical speed governor is operated in the Droop speed control mode.

Notes:

Distracter A is incorrect because the electrical governor only operates in the Isochronous mode when there is no offsite power or a SIAS has occurred.

Distracters B is incorrect because the mechanical governor is the backup governor and does not control the EDG speed when paralleled to offsite.

Distracter D is incorrect because the mechanical governor droop speed control is set to zero (0) so there is always a constant isochronous speed on the EDG when the backup Mechanical governor take over should the electrical governor fail.

Reactor Power 62 RO Sort:

Question:

Given the following:

• The plant is at full power.

• A Condenser tube leak occurs in the outer pass waterbox.

• Plant power is reduced to 90% to isolate the outer pass waterbox.

• Steam Dump and Bypass Control System (SDBCS) Valves 2CV-303 and 2CV-306 are defeated from opening by placing their permissive switches in OFF.

• All other SDBCS components are in their normal positions.

Based on the above conditions and with no operator action, what is the remaining total steam flow capacity of the Steam Dump and Bypass Control System should the Main Turbine trip?

A. ~ 25%

B. ~ 30%

C. ~ 35%

D. ~ 55%

Answer:

C. ~ 35%

Notes:

There are 4 SDBCS ADV at 11.5% capacity each and three steam dumps to the condenser, two at 11.5% each and one at 5%. Two of the ADVs upstream of the MSIVs are normally isolated by an electric MOV because they fail open on a loss of IA and have to be placed in service manually.

2CV-303 is the 5% Steam dump and 2CV-306 has a capacity of 11.5%. With these conditions, there are two ADVs and one steam dump left to automatically control steam flow and Reactor Power should the turbine trip.

All three have a capacity of 11.5% so the total capacity left is approximately 35%

Distracter A is incorrect but would be the answer if the trainee thought there were only two ADVs left for steam flow control and all Steam dumps were defeated.

Distracter B is incorrect but would be the answer if the trainee incorrectly calculated that 2CV-303 had a 105

Questions For 2005 RO and SRO Exam 14-Jan-05 capacity of 11.5% instead of 5%.

Distracter D is incorrect but would be the answer if the trainee did not remember the upstream ADVs were manually actuated only and added the capacity of these valves.

Plant conditions are:

• A LOCA has occurred.

• Whole body dose rates are 3 Rem/hr in the "B" SDC Heat Exchanger Room.

• An "ALERT" Emergency Classification has been declared.

A female WCO who is NOT declared pregnant with complete exposure records is assigned to align the "B" SDC train for decay heat removal. This job is expected to take 30 minutes. The WCO has a radiation history of 1000 mrem exposure for this year.

Which of the following statements is correct for the additional dose that would be received by performing this system alignment with the above conditions?

A. WCO will NOT exceed routine annual ANO Admin whole body (TEDE) limits for radiation workers.

B. WCO will NOT exceed routine annual ANO Admin whole body (TEDE) limits for female radiation workers.

C. WCO will exceed annual Federal whole body (TEDE) limits for female radiation workers.

D. WCO will exceed routine annual ANO Admin whole body (TEDE) limits for radiation workers.

Answer:

D. WCO will exceed routine annual ANO Admin whole body (TEDE) limits for radiation workers.

Notes:

Radiation history of 1000 mrem shows that WCO is a radiation worker with limits the same as males.

A is incorrect because the TEDE ANO Routine Admin limit is 2 Rem/yr for rad workers. Total exposure after this job would be 2.5 Rem.

B is incorrect because the ANO Routine Admin limits are the same for Female rad worker who is not pregnant and rad worker.

C is incorrect because Federal limits are 5 Rem/yr..

D is correct because the additional dose is 1500 mrem which is added to 1000 mrem to make 2500 mrem which exceeds the admin limit of 2.0 Rem/yr.

The following conditions exist after a Reactor trip during performance of SPTAs:

• RCS pressure 1650 psia (lowering slowly)

• RCS Thot 552 degrees F (lowering slowly)

• RCS Tcold 551 degrees F (lowering slowly)

• PZR level 5% (lowering slowly)

• Containment pressure19.1 psia (rising slowly)

• Containment Radiation Monitors are trending up

• SIAS, CCAS, CIAS Actuated

• All 4 RCPs are running Which one of the following actions should be taken regarding the RCPs?

A. Leave the RCPs running and restore CCW flow.

B. Leave the RCPs running and restore controlled bleedoff.

C. Stop all RCPs due to LOCA condition and loss of CCW.

D. Stop all RCPs due to imminent containment spray actuation.

Answer:

A. Leave the RCPs running and restore CCW flow.

Notes:

The goal in the EOPs is to maintain forced circulation as long as possible to assist in the subsequent cooldown after a mass loss event such as LOCA. Therefore as CCW is lost due to the CIAS, the SPTA Step 7.B contingency is to restore RCP cooling to keep forced circulation as long as possible.

Distracter B is incorrect because RCP controlled bleedoff cannot be restored to a normal lineup until the SIAS is reset and the conditions to reset SIAS are not met.

Distracter C is incorrect because the RCPs are only secured on low NPSH or a CSAS which has not happened yet.

• EFW Pump 2P7A Overspeed Trip comes in when EFAS is actuated during SPTAs.

• The WCO reports that the 2P-7A Overspeed Trip reset linkage cannot be reset.

• Steam Generator Levels are 34% each and dropping.

Which procedure should the crew transition to after SPTAs and what action should Chemistry perform during the implementation of this procedure?

A. Loss of Feedwater EOP; sample the RCS for iodine 2 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> post Reactor Trip.

B. Loss of Offsite Power EOP; sample both Steam Generators for activity.

C. Loss of Feedwater EOP; sample both Steam Generators for activity.

D. Loss of Offsite Power EOP; sample the RCS for iodine 2 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> post Reactor Trip.

Answer:

A. Loss of Feedwater EOP; sample the RCS for iodine 2 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> post Reactor Trip.

Notes:

No Feedwater source is available under these conditions and the Loss of Feedwater EOP will provide direction to get a power source to the B EFW Pump so this is the procedure to transition to. The sampling of the RCS is a TS requirement to assess fuel damage due to the event.

Distracter B is incorrect because the wrong EOP is implemented and the SGs should not be sampled because cooling water to the sample coolers is lost therefore this direction is not given in the appropriate EOP. The EOP actually directs closure of the SG sample valves to conserve FW inventory.

Distracter C is incorrect because the EOP actually directs closure of the SG sample valves to conserve FW inventory.

Distracter D is incorrect because the wrong EOP is implemented.

Given the following conditions:

• A PZR steam space Loss of Coolant accident is in progress.

• Both Trains of HPSI and all three charging pumps are in service

• RCS temperature is 550 degrees F and steady.

• RCS pressure is 1250 and restoring slowly.

• RVLMS level 5 and below indicate WET.

• PZR Level is 89% and rising rapidly.

• SPTAs are complete and the LOCA EOP 2202.003 has been entered.

Based on these conditions, which of the following actions should be directed to prevent potential over pressurization of the RCS?

A. Stop all Charging pumps and throttle HPSI injection MOVs to limit PZR level.

B. Maintain all Charging and HPSI pumps running with full flow to the RCS.

C. Stop all Charging pumps but maintain full HPSI pump injection flow to the RCS.

D. Stop all Charging pumps and place all HPSI pump handswitches in Pull To Lock.

• The unit is shutdown for a refueling outage

• RCS pressure is 260 psia

• RCS temperature is 215°F

• One train of shutdown cooling is in service

• 2PT-4623-1 (pressurizer low range pressure transmitter) fails high.

Which of the following Operator actions should be taken?

A. Override all SIT outlet valves due to automatically opening.

B. Stop the running SDC pump due to a loss of suction from the RCS.

C. Place all HPSI and LPSI pumps in PTL due to initiation of a SIAS.

D. Place all Normal Spray Valves to manual and closed due to opening.

B. Stop the running SDC pump due to a loss of suction from the RCS.

Notes:

The pressure transmitter failing high will cause SDC suction isolation 2CV-5084-1 to go closed and the AOP for loss of SDC directs securing the running SDC pump.

Distracter A is incorrect because the SIT outlet valve MOV breakers are de-energized after they are closed at

~650 psia during a cooldown.

Distracter C is incorrect because an SIAS is actuated on the Wide Range PZR Pressure Transmitters and the SIAS Low PZR Pressure actuation's have been bypassed on the PPS ROMs.

Distracter D is incorrect because the normal spray valves open on Control Channel PZR Pressure Transmitters which have not failed.

Question:

Given the following:

• The plant is at full power at the end of a cycle preparing to shutdown in 1 week.

• A Unit 2 Gaseous Release Permit has been issued for Gas Decay Tank (GDT) 2T-18A.

• The source check on the GDT Vent Line Radiation Monitor 2RITS-2429 has failed.

• The radiation monitor will not come off of the low end of the scale.

• The Shift Manager has declared 2RITS-2429 inoperable.

Which of the following statements is TRUE concerning the release of 2T-18A?

A. The release CAN proceed as long as an independent verification of the discharge path valve lineup and an independent sample of 2T-18A activity is analyzed first.

B. The release CAN proceed as planned as long as the Auxiliary Building Exhaust Dose Assessment SPING 6 is operable to monitor the activity being released.

C. The release CANNOT proceed until 2RITS-2429 has been returned to Operable status in accordance with ODCM L2.2.1 requirements.

D. The release CANNOT proceed because the discharge flow path cannot be aligned with 2RITS-2429 failed offscale Low.

Answer:

A. The release CAN proceed as long as an independent verification of the discharge path valve lineup and an independent sample of 2T-18A activity is analyzed first.

Notes:

Distracter B is incorrect because the SPING does not automatically shutoff the release on high activity and this is not allowed without independent samples and lineup.

Distracter C is incorrect because the release can still be completed with independent samples and lineup.

Distracter D is incorrect because the interlock to isolate the discharge flowpath will only occur on a high radiation signal or the rad monitor failing high.

Given the following conditions:

(Reference Provided)

• Unit 2 is at 100% power.

• Air in leakage to the condenser has resulted in steadily degrading condenser vacuum.

• A load reduction is in progress in order to maintain vacuum.

• With the unit at approximately 85% power, vacuum degrades rapidly causing a Turbine Trip and the Reactor Trips on high RCS pressure.

• All systems function as designed.

Which of the following is TRUE concerning the notification requirements for this event?

A. The NRC must be notified within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> due to the Reactor Trip at power.

Question:

Consider the following:

(Reference Provided)

• A fire occurs in the Unit 2 Control Room causing severe damage to 2C16 and 2C17.

• The SM determines that an Alternate Shutdown is necessary.

• Actions are taken in accordance 2203.014, Alternate Shutdown Procedure

• 20 minutes later there is no EFW flow to either steam generator.

Given the above plant conditions, determine the appropriate Emergency Action Level Classification:

A. Notification of Unusual Event.

B. Alert.

C. Site Area Emergency.

D. General Emergency.

Answer:

C. Site Area Emergency.

Notes:

Since the Control Room has to be evacuated due to the fire and local control of EFW which is a shutdown system, then a SAE should be declared. Main feedwater Pumps are tripped per 2203.014.

Distracter A is incorrect because the Control room is evacuated which is an ALERT as a minimum.

Distracter B is incorrect because local control of a shutdown system has not been established in 15 minutes.

Distracter D is incorrect because there is no release in progress that would warrant an upgrade to a General Emergency.

This question will require the procedure 1903.010 be provided as a reference.
