Given the following:
- The plant has tripped from full power.
- Both Steam Generators are at 1000 psia.
Which of the following conditions meet safety function criteria to ensure an adequate heat sink for RCS Heat Removal in the Standard Post Trip Actions (SPTA)?
A. SG levels at 5 % with "A" MFWP in Reactor Trip Override.
B. SG levels at 23% with EFW Pump 2P7A total flow of 615 gpm.
C. SG levels at 35% with EFW and MFW Pumps NOT available.
D. SG levels at 95% with both MFW pumps in High Level Override.
Answer:
B. SG levels at 23% with EFW Pump 2P7A total flow of 615 gpm.
Notes:
A is incorrect because level in one SG must be 10 - 90% AND MFWP available.
B is correct because the EFW pump with greater than 485 gpm flow and SG level is between 10-90%
C is incorrect because even though level is in 10 - 90% band, no makeup flow available.
D is incorrect because level is above 10 - 90% range and contingency actions call for MFW pump trip.

F Question:
Given the following plant conditions:
- Thirty (30) minutes post trip from full power due to a LOCA in the top of the Pressurizer.
- Pressurizer Level has risen to 100%.
- RVLMS level 6 is wet and slowly dropping.
- All RCPs have been secured.
- RCS pressure is 1350 psia and slowly rising.
- Auxiliary Spray is in service.
Which ONE (1) of the following would be the purpose and function of using the RCS High Point Vents during these conditions?
A. To equalize pressure between the Pressurizer and Reactor Vessel to allow RCP restart.
B. To vent the Pressurizer to the Containment atmosphere to prevent Quench Tank rupture.
C. To reduce pressure in the top of the Pressurizer to prevent PZR Safeties from lifting.
D. To depressurize and eliminate voids in the Reactor Vessel that could inhibit natural circulation.
Answer:
D. To depressurize and eliminate voids in the Reactor Vessel that could inhibit natural circulation.
Notes:
A is incorrect because RCP restart criteria is not met because PZR level is not controlled.
B and C are not correct because the high point vent have a restriction orifice in the line to limit the amount of pressure reduction in the RCS and this limited capacity would not prevent the safeties from lifting under these conditions and also would not protect the Quench Tank from rupture.
D is correct because the void in the head is growing and pressure is not dropping during the cooldown. This is impeding the reduction in RCS pressure and also starting to block off the hot leg outlet from the core thus impeding natural circulation.

C. To ensure reflux boiling is the primary means of heat removal prior to voiding in the hot legs.
D. To ensure natural circulation will be established in the RCS since ALL RCPs must be secured.
Answer:
B. To ensure adequate RCS heat removal because cooling from HPSI flow alone may be inadequate.
Notes:
Answer "A" is incorrect because RCS pressure control will be maintained by spray flow into the Pressurizer.
Answer "C" is incorrect because reflux boiling in not expected to occur on a small break LOCA.
Answer "D" is incorrect because a RCPs will not need to be secured at this pressure.

Given the following:
- Following a reactor trip and Safety Injection Actuation Signal (SIAS) caused by a Primary Coolant System depressurization, it is required to trip two (2) Reactor Coolant Pumps and leave two (2) RCPs operating at a certain RCS pressure.
Which one (1) of the following is the reason for this action?
A. Allows forced circulation during plant cooldown if a large break Loss of Coolant Accident (LOCA) does not exist.
B. Allows adequate seal cooling flow to the remaining two RCPs during the loss of the seal injection driving head.
C. Prevents excessive current draw from the Startup #2 Transformer after the 2H1 and 2H2 electrical buses have transferred offsite.
D. Prevents rapid Reactor Coolant System cooldown during an Excess Steam Demand (ESD) event.
Answer:
A. Allows forced circulation during plant cooldown if a large break Loss of Coolant Accident (LOCA) does not exist.
Notes:
Answer "B" is not true because seal injection flow will drop but still be adequate at the RCS pressure required to trip 2 pumps.
Answer "C" is not true because the RCP power supply busses 2H1 and 2H2 transfer to SU #3 transformer which has more than adequate capacity to operate all 4 pumps.
Answer "D" is not true for a cooldown with 0, 2, or 4 pumps running but based on break size.

F Question:
Which one (1) of the following conditions requires the plant to be tripped and the affected Reactor Coolant Pump (RCP) to be stopped as soon as the condition is met AND what is the reason for securing the pump?
A. Seal Bleedoff flow greater than 3.0 gpm; to prevent overcooling the pump seals.
B. Motor Winding Temperature is rising and alarm is in; to prevent damage to the pump motor.
C. Vapor Seal Pressure reaches 750 psia; to prevent a Loss of Coolant Accident.
D. Component Cooling Water Flow is lost for 5 minutes; to prevent overheating the pump seals.
Answer:
B. Motor Winding Temperature is rising and alarm is in; to prevent damage to the pump motor.
Notes:
Answer "A" is incorrect because seal bleedoff greater than 3.0 gpm requires plant shutdown, not a trip and high flow would overheat the seals.
Answer B is correct because damage to the motor cannot be repaired and the pump would eventually trips it power supply breaker and cause a loss of flow to the core which could cause fuel damage.
Answer "C" is incorrect because vapor seal pressure must be 1500 psia to require a trip.
Answer "D" is incorrect because CCW must be lost for greater than 10 minutes to require a reactor trip.

R Difficulty: 3 Taxonomy: H Question:
Given the following conditions:
- The plant is shutdown to replace a failed RCP seal.
- OP 1015.008 Attachment B, Unit 2 SDC Control, has just been completed.
- SDC Pump 2P60A is in service through SDC HX 2E-35A with the same flows established during completion of OP 1015.008 Attachment B.
- The RCS is currently in reduced inventory
- RCS Temperature is 115°F and steady.
- Now a loss of 125 VDC power to the SDC Temperature Control Valve 2CV-5093 solenoid causes the temperature control valve to go to its failed position.
- All other components in the SDC system remain the same as before the failure.
Which of the following would be the effect on RCS Temperature?
A. RCS temperature would rise slowly due to approximately 25% loss of flow through 2E-35A.
B. RCS temperature would rise rapidly with a loss of cooling due to 2CV-5093 failing full closed.
C. RCS temperature would drop slowly due to approximately 25% additional flow through 2E-35A.
D. RCS temperature would drop rapidly with much more cooling due to 2CV-5093 failing full open.
Answer:
A. RCS temperature would rise slowly due to approximately 25% reduction of flow through 2E-35A.
Notes:
2CV-5093 will lose IA on a loss of power to its DC solenoid causing the valve to fail closed. However, OP 1015.008 Attachment B Step 6.2 throttles the SDC Temperature Control Valve 2CV-5093 Bypass Valve 2SI-5093-3 to ensue at least 75% of the flow from the SDC HX is available as a mitigation strategy should 2CV-5093 fail Closed. This makes answer A correct.
Distracter B is incorrect because there is still 75% of the flow going through the bypass so the temperature would not go up rapidly.
Distracter C is incorrect because cooling flow is lowered not raised.
Distracter D is incorrect because cooling flow is lowered not raised.

- Steam Generator B pressure is 750 psia and rising.
- Containment pressure is 14.7 psia and steady.
- RCS pressure is 1725 psia and dropping.
- No operator actions have been taken.
- All components actuate as designed.
Based on the above conditions, what is the current position of Service Water to CCW Heat Exchanger Inlet Valves 2CV1530-1 and 2CV-1531-2 AND what is the reason for these positions ?
A. Both Isolation Valves are OPEN and can be overridden CLOSED as needed; to ensure Service Water cooling is available to CCW system loads.
B. Both Isolation Valves are OPEN and cannot be overridden CLOSED unless ESF actuations reset; to ensure Service Water cooling is available to CCW system loads.
C. Both Isolation Valves are CLOSED and can be overridden OPEN as needed; to ensure the RED and GREEN trains of Service Water are separated from the CCW system.
D. Both Isolation Valves are CLOSED and cannot be overridden OPEN unless ESF actautions reset; to ensure the RED and GREEN trains of Service Water are separated from the CCW system.
Answer:
C. Both Isolation Valves are CLOSED and can be overridden OPEN as needed; to ensure the RED and GREEN trains of Service Water are separated from the CCW system.
Notes:
A is incorrect because the Low SG pressure will cause a MSIS which will close both valves. A SIAS signal will close both valves also but has not occurred yet.
B is incorrect because the Low SG Pressure MSIS signal will close both valves.
C is correct because the valves have override capability to continue to cool CCW loads if enough SW flow is available in accident conditions.
D is incorrect because both valves can be overridden OPEN with a MSIS signal present.

What would be the direct effect of these conditions on Unit 2?
A. These conditions would cause two reactor trip circuit breakers to open AND NO Reactor trip.
B. These conditions would cause four reactor trip circuit breakers to open AND a Reactor trip.
C. These conditions would cause only the 'A' CEA MG Set output contactor to open AND NO Reactor trip.
D. These conditions would cause the 'A' and 'B' CEA MG Set output contactors to open AND a Reactor Trip.
Answer:
D. These conditions would cause the 'A' and 'B' CEA MG Set output contactors to open AND a Reactor Trip.
Notes:
A and B are incorrect because these pressure transmitters are independent of the pressure transmitters that feed RPS and Reactor trip breakers would not open initially but all 8 circuit breakers eventually would trip open due to LPD and DNBR trips.
C is incorrect because 2 out of 4 ATWS pressure transmitters failing high will give a full output opening both disconnect contactors causing a Reactor trip which make D the correct answer.

- The plant has tripped from 100% Power.
- RCS pressure is 1600 psia and lowering.
- RCS T-cold is 505°F and lowering.
- Pressurizer Level is 10% and lowering.
- Containment pressure is 14.5 psia and stable.
- Containment temperature is 110°F and stable.
- No radiation alarms are present inside Containment or on the Main Steam lines.
- A Steam Generator pressure is 610 psia and lowering.
- B Steam Generator pressure is 610 psia and lowering.
- A Steam Generator level is 20% NR and lowering.
- B Steam Generator level is 20% NR and lowering.
- No Main Steam Safeties have lifted.
- No other abnormal conditions exist and all components have actuated as designed.
- All systems function as designed.
Which ONE of the following actions should be taken to stabilize plant pressure and temperature?
A. Close both MSIV bypass valves and secure steaming to the Main Condenser.
B. Take manual control of the MFW system and minimize feed to Steam Generators.
C. Close both Main Steam isolation valves to the EFW Pump Terry Turbine, 2P7A.
D. Take manual control of the HPSI system and throttle the excess flow to the RCS.
Answer:
C. Close both Main Steam to the EFW Pump Terry Turbine, 2P7A, isolation valves.
Notes:
Answers A and B are both incorrect because a MSIS should have already occurred causing the MSIV bypass valves and Main Feed Isolations to close so an excessive steaming path downstream of the MSIVs or an excessive feeding to the SGs should not exist.
Answer C is correct because the steam isolations to the Terry Turbine are upstream of the MSIVs, outside containment and they cross connect both Steam Generators.
Answer D is incorrect because even though a SIAS has been initiated, the RCS pressure is still above the shutoff head of a HPSI pump so excessive cooling flow from the HPSI pumps should not exist.

Given the following:
- The plant is at full power.
- A 200 gpm Main Feedwater line break downstream of Main Feedwater Check valve (2FW-5A) occurs.
- Containment temperature, pressure and humidity start rising.
- The plant is manually tripped.
- EFAS is manually actuated.
Based on these conditions the affected Steam Generator will depressurize and start an uncontrolled cooldown when:
A. Steam Generator 'A' level drops below 22.3% Narrow Range level.
B. The main feedwater isolation valve is closed to "A" Steam Generator.
C. Main and Emergency Feedwater to "A" Steam Generator is secured.
D. Steam Generator 'A' level drops below 300 inches Wide Range level.
Answer:
C. Main and Emergency Feedwater to "A" Steam Generator is secured.
Notes:
As long as a feed source exists to "A" Steam Generator, the feed source will be at a higher pressure than the Steam Generator, therefore the feed source (MFW/EFW) will be going out the leak. Once all feed is secured by MSIS & 90# delta P then steaming of the generator through the break will occur and cause an uncontrolled cooldown.

Which of the following actions will need to be taken locally to allow crosstie of 2Y2 from 2Y1 to restore Control Room instrumentation and control and prevent re-energizing the buses from two sources?
A. The 2Y1 Main Feeder Breaker MANUAL TRIP button must be pushed in to remove the Kirk Key from the 2Y1 Feeder Breaker to allow obtaining the crosstie breaker Kirk Keys.
B. The 2Y2 Main Feeder Breaker MANUAL TRIP button must be pushed in to remove the Kirk Key from the 2Y2 Feeder Breaker to allow obtaining the crosstie breaker Kirk Keys.
C. The 2Y1 Main Feeder Breaker MANUAL CLOSE button must be pushed in to remove the Kirk Key from the 2Y1 Feeder Breaker to allow obtaining the crosstie breaker Kirk Keys.
D. The 2Y2 Main Feeder Breaker MANUAL CLOSE button must be pushed in to remove the Kirk Key from the 2Y2 Feeder Breaker to allow obtaining the crosstie breaker Kirk Keys.
Answer:
B. The 2Y2 Main Feeder Breaker MANUAL TRIP button must be pushed in to remove the Kirk Key from the 2Y2 Feeder Breaker to allow obtaining the crosstie breaker Kirk Keys.
Notes:
The Kirk Keys are normally captured in the feeder breakers when the breakers are closed. The feeder breaker Kirk keys are needed to obtain the crosstie breaker Kirk keys to allow closing the crosstie breakers to restore the control room instrumentation and control. To obtain the feeder breaker Kirk keys and ensure the supplying bus is not cross tied to the other safety bus, the feeder breaker Kirk key can only be removed when the feeder breaker trip pushbutton is depressed. Since the condition requires powering 2Y2 from 2Y1, the feeder breaker we need to open is the normal feeder breaker for 2Y2. This makes Answer B Correct. Distracter A would be used only if 2Y1 was to be supplied from 2Y2. Distracters C and D would not meet the interlock and thus are incorrect.

A. 0.1 B. 1.0 C. 100 D. 10000 Answer:
A. 0.1 Notes:
Sub critical multiplication factor should be rising exponentially to an infinite number when the reactor is approaching criticality. Thus the 1/M reading should be approaching Zero which makes A correct. The student may incorrectly assume that 1/M approaches infinity and pick D. If the count rate does not change at all, then B would be a viable answer which the student may assume since boron concentration is not changing.

- The plant has tripped due to a Loss of Offsite Power 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> ago.
- A bus lockout occurs on Electrical Bus 2A3 and cannot be reset.
- The Loss of Feed Water EOP, 2202.006 has been entered.
- RCS Tave is 545°F and being maintained with Atmospheric Dump Valves (ADVs).
- "A" Steam Generator level is 80 inches and dropping
- "B" Steam Generator level is 60 inches and dropping.
The correct action to take based on these conditions would be to:
A. Establish Once Through Cooling with HPSI flow to remove RCS heat at this time.
B. Establish Once Through Cooling to remove RCS heat at < 75 inches in both SGs.
C. Establish Once Through Cooling only after RCS temperature starts to rise.
D. Establish Once Through Cooling for RCS heat removal after SGs are < 22%.
Answer:
A. Establish Once Through Cooling with HPSI flow to remove RCS heat at this time.
Notes:
By the Guidance found in the Loss of Feedwater EOP 2202.006, Once Through Cooling should be established when either SG is < 70 inches or RCS T-cold is rising in an uncontrolled manner. Once Through Cooling should be established before transitioning to the FRP. 22% Narrow range SG level is the in the Optimum EOPs to establish an emergency feedwater source.

This question was generated from a randomly selected K/A to be part of the 2002 SRO exam and not on the 2002 RO exam; however, this question is not one of the 25 10 CFR 55.43 category questions selected for this exam. Four additional questions were selected to be on the 2002 SRO exam that are not on the 2002 RO exam to in order to comply with the NUREG 1021 guidance to have a balance of K&A selections on the initial sample plan. One of these 4 happen to fall into the 10 CFR 43 category so there are actually 26 SRO only questions on the 2002 SRO exam that are in the 10 CFR 43 category.

- A plant trip from full power has occurred as a result of a large steam line rupture.
- Containment pressure reaches 24.2 psia and rising
- RCS pressure is 1475 psia and dropping
- RCS temperature is 520°F and lowering According to 2202.005, Excess Steam Demand, what, if any, actions are required concerning the Reactor Coolant Pumps (RCPs)?
A. Stop all RCPs due to a loss of NPSH to the RCPs.
B. Stop 1 RCP in each loop to minimize heat input to the RCS.
C. Stop all RCPs to prevent damage to the RCP motors.
D. Leave all RCPs running to assist in recovering the plant after cooldown.
Answer:
C. Stop all RCPs to prevent the damage to the RCP motors.
Notes:
The EOP requires RCPs to be secured if NPSH is lost (MTS less than 30 degrees F) which is not the case in these conditions so distracter A is incorrect.
One RCP in each Loop if RCS Pressure in less than 1400 psia to minimize loss of inventory which is not the case in these conditions which makes distracter B incorrect.
Based on Containment Pressure, Containment Spray Actuation (CSAS) has occurred and all RCPs are required to be secured for a CSAS to prevent motor winding damage. The only criteria met in the condition above is Containment pressure above CSAS setpoint of 23.3 psia. Therefore, the procedure direct securing of all RCP to save the motor from boric acid contamination.
D is incorrect because all RCPs are required to be secured.

A. 200; would be lower B. 200; would be higher C. 15; would be lower D. 15; would be higher Answer:
A. 200; would be lower Notes:
The RCS loop charging isolations are normally closed during RCS seal injection. The bypass valve around 2CV-4827 is a spring loaded check valve set at 200 psid. This allow 200 psi of pressure to the seal injection line to provide the motive force for RCP seal injection during RCS fill and vent with the RCS open to atmospheric pressure. If RCS Loop Charging Isolation Valves, 2CV 4831-2 or 2CV-4827-2 are opened then the CVCS flow would take the path of least resistance and go into the RCS loops instead of the RCP seals.

Given the following:
- The plant is at 100% power
- CCW Pumps 2P33A and 2P33B are in Standby.
- Annunciators 2K11-A1/A3/A5/A7 "CCW DISC FLOW LO" come in.
- CCW Containment Supply Valve 2CV-5632-1 on 2C-17 has closed.
Which of the following actions should be taken first based on these alarms and indications?
A. Start CCW Pumps 2P33A and 2P33B to clear alarms then place 2P33C in Pull to Lock (PTL).
B. Trip the Reactor and commence EOP Standard Post Trip Actions (SPTAs).
C. Enter the RCP Emergencies AOP and attempt to restore CCW to the RCPs.
D. Trip the Reactor and isolate Controlled Bleedoff from the RCPs due to loss of CCW cooling.
Answer:
C. Enter the RCP Emergencies AOP and attempt to restore CCW to the RCPs.
Notes:
These alarms are entry conditions for the RCP Emergency AOP and monitor CCW flow to the Containment.
These are RED colored Annunciators (Highest Priority) and require prompt action because if CCW cannot be restored within 10 minutes, then the plant should be tripped and the RCPs secured.
Starting the CCW pumps would not mitigate the event since the Containment CCW supply valve has failed closed.
Isolating controlled bleedoff would be an action after the plant trip if CCW cannot be restored to prevent cooking the RCP seals.

Consider the following:
- The plant is operating normally at full power.
- RCS Pressure is 2200 and steady.
- The 'A' Pressurizer Pressure Control Channel is in service and fails high.
- No Operator Action has been taken.
Given these conditions, which of the following would occur AND what effect would it have on the Pressurizer Heaters?
A. Both spray valves will go 40% open causing RCS pressure to lower; All PZR heater breakers will close with proportional heaters going to maximum firing B. Both spray valves will go 100% open causing RCS pressure to lower; All PZR heaters breakers remain as before with proportional heaters going to minimum firing.
C. Both spray valves will remain closed causing RCS pressure to rise; All PZR heater breakers would open.
D. The "A" Spray valve goes 100% open, the "B" Spray valve remains closed, causing RCS pressure to lower; All PZR heaters breakers remain as before the failure.
Answer:
B. Both spray valves will go 100% open causing RCS pressure to lower; All PZR heaters breakers remain as before with proportional heaters going to minimum firing.
Notes:
A is incorrect because the proportional heater breakers will not open but fire at a lower rate. Also the Spray valves only go to a 40% position between 25 to 40 psi above controller setpoint.
C is incorrect because the spray valves will come open, the RCS pressure will lower and the heater breakers will not close on a high failure.
D is incorrect because the in-service PZR Pressure control channel failing high will affect both RCS spray valves and provide enough spray flow to reduce RCS pressure even with all the heaters energized.

Given the following:
- The plant has tripped from 100% power due to an Excess Steam Demand.
- All RCPs have been secured.
- RCS pressure initially lowered then started rising and is currently 1600 psia.
- RCS temperature is 485°F and rising.
- RCS Pressure Control is being established with Auxiliary Spray.
In accordance with EOP Standard Attachment 27, which of the following actions should be taken and why?
A. Stop all Charging Pumps to prevent thermal shock to the RCS Spray nozzles.
B. Isolate Letdown to prevent exceeding design temperature limits of the spray header piping and nozzles.
C. Log the Open and Closing times of Aux Spray Valve 2CV-4824-2 to comply with spray nozzle usage limits.
D. Take the Letdown Flow Controller to manual and raise Letdown Flow to Maximum to limit the CVCS to RCS Delta Temperature.
Answer:
C. Log the Open and Closing times of Aux Spray Valve 2CV-4824-2 to comply with spray nozzle usage limits.
Notes:
Anytime Auxiliary Spray is initiated with a differential temperature between the Regenerative Heat Exchanger Outlet to the RCS and the pressurizer water phase exceeding 200 °F, then record the length of time of spraying operation and the difference in temperature. The pressurizer spray nozzle is designed to allow using the spray valves 100 times per year with the differential temperature between the spray fluid and the pressurizer in excess of 200 °F.
In addition to the above requirement, if the Regenerative Heat Exchanger Outlet to the RCS temperature exceeds 275 °F and Aux Spray is used, an engineering evaluation is required before normal operation of the Auxiliary Spray is allowed. The Auxiliary Spray line is qualified for only one use with temperature > 275 °F.

C. One MFWP running, no MFW block valves closed.
D. One MFWP running, all 4 MFW block valves closed.
Answer:
A. Both MFWPs tripped, all 4 MFW block valves closed.
Notes:
During Steam Generator Replacement Outage, 2R-14, a design change was installed to provide modifications to actuate equipment necessary to prevent exceeding the CB pressure limits. This was accomplished by using the Hi-Hi Containment Pressure (CSAS) signal at 23.3 psia to terminate forced MFW flow, isolate MFW, and terminate MS flow. This termination and isolation is accomplished through generation of a Main Feedwater Isolation Signal (MFWIS). CSAS and MSIS actuation relay contact combination were applied to actuate the components that isolate MFW and MS. This arrangement will terminate forced flow, such that the MFW isolation and/or backup valves can close, stop the Condensate Pumps, Heater Drain Pumps, and MFW pumps.

D. RCS pressure will rise, PZR level will rise, Reactor power will lower.
Answer:
D. RCS pressure will rise, PZR level will rise, Reactor power will lower.
Notes:
The loss of steam load will cause an increase in RCS temperature which will cause an insurge to the pressurizer causing a rise in pressure and level. The rise in temperature will induce negative reactivity in the core with a negative MTC thus causing Reactor power to lower - follows steam demand. This question is also tied to GFES Reactor Theory Chapter 8 Reactor Operational Physics, Objective 21.

Given the following: (Reference Provided)
- Alarm 2K01 H-10 "BATTERY 2D11 GROUND" has come in at full power.
- At the Fuse and Relay Panel for 2D11, 2D41, the following readings are reported.
- The V1 Positive Voltage is reading 43 VDC
- The V2 Negative Voltage is reading 82 VDC
- Electrical Maintenance has been contacted for troubleshooting.
Based on these indications which of the following is correct AND what action should be taken in accordance with OP 2107.004?
A. There is a very low resistance positive ground on the Red DC bus; generate a condition report and enter the applicable Technical Specifications.
B. There is a very low resistance negative ground on the Red DC bus; contact system engineering and initiate a WR/WO.
C. There is a very high positive ground on the Red DC bus; generate a condition report and a WR/WO.
D. There is a very high negative ground on the Red DC bus; generate a condition report and enter the applicable Technical specifications.
Answer:
C. There is a very high positive ground on the Red DC bus; generate a condition report and a WR/WO.
Notes:
The positive and negative voltage indications can be used to determine if a ground exists on the respective DC bus. A ground is indicated by a voltage difference between the two ground referencing voltmeters (V1 and V2), with the grounding condition on the polarity with the least of the two voltages.
The 125V DC System is an ungrounded electrical system. This design prevents a single ground from rendering equipment inoperable or causing spurious operation of equipment.
The procedure 2107.004 directs the following:
Perform the following based upon local V1 and V2 readings:
IF voltage on either of the two meters (V1 or V2) is greater than 20 but less than 50, THEN a very high ground is indicated. Perform the following: Initiate a WR/WO and Initiate a Condition Report.
Provide OP 2107.004, DC System Operations, Section 7.0 as a reference.

D. Red Battery Disconnect open; power to Red train vital inverters and starting of Emergency Diesel 2DG1 during a Loss of Offsite Power (LOOP).
Answer:
C. Green Battery Disconnect open; power to Green train vital inverters and starting of Emergency Diesel 2DG2 during a Loss of Offsite Power (LOOP).
Notes:
2D11 is the Green train vital DC battery. Opening this disconnect will remove the uninterruptible power source to the green train vital inverters and the green train EDG. If a LOOP were to occur in this condition, the green EDG would not start because DC is needed to open the air start solenoids and the green train vital inverters would loose their alternate AC source of power.

- Both EDGs start and their output breakers close as designed.
Which ONE (1) of the following list the major pump starts on the safety busses in the correct order beginning with the first pump start AND the reason why they sequence onto the vital buses at various times?
A. Service Water Pumps, HPSI Pumps, LPSI Pumps, Charging Pumps; to ensure RCS inventory and cooling are provided in the correct order.
B. Service Water Pumps, HPSI Pumps, LPSI Pumps, Charging Pumps; to limit the amount of current drawn from the EDGs during pump starts.
C. HPSI Pumps, Service Water Pumps, Charging Pumps, LPSI Pumps; to ensure RCS inventory and cooling are provided in the correct order.
D. HPSI Pumps, Service Water Pumps, Charging Pumps, LPSI Pumps; to limit the amount of current drawn from the EDGs during pump starts.
Answer:
B. Service Water Pumps, HPSI Pumps, LPSI Pumps, Charging Pumps; to limit the amount of current drawn from the EDGs during pump starts.
Notes:
The Service Water pumps supplies cooling for the EDG, HPSI and LPSI pumps so it is the first motor to start.
The HPSI then LPSI then Charging are next to address the RCS inventory concerns. The large amount of counter EMF exhibited during large motor starts will be seen as a large current draw on the EDG degrading voltage and frequencies so the motors are sequenced onto the diesel to limit the current generated if all the motors started at once.

Notes:
The LRW/BMS Process Radiation Monitor, 2RITS-2330, provides an automatic closure of 2CV-2330A and/or 2CV-2330B. This automatic feature occurs on a high alarm that is determined by the Unit 2 Liquid Radwaste Release Permit (2104.014 Supp 1). Going to PULSE Cal will raise the detector radiation output above the alarm setpoint causing the valve to go closed. Testing of this interlock will prevent discharging liquid waste above the design limits.

C. Only two purge isolation valves close. The exhaust fan trips on LOW pressure in the exhaust duct and the supply fan trips 10 seconds later.
D. All six purge isolation valves close. The supply fan trips on HIGH pressure in the supply duct and the exhaust fan trips 10 seconds later.
Answer:
B. All six purge isolation valves close. The exhaust fan trips on LOW pressure in the exhaust duct and the supply fan trips 10 seconds later.
Notes:
If an SIAS or a CIAS is received, all six purge isolation valves automatically close compared to only 2 isolation valves on a high radiation signal. When this happens, the exhaust fan draws down the pressure in the exhaust duct to less than -5.0 inches water gauge tripping the exhaust fan. Ten seconds later the supply fan trips.

Given the following:
- The plant is at full power during the middle of an operating cycle.
- The Main Turbine Trips.
- No operator action is taken.
Prior to any Reactor trip, what would be the primary plant temperature and pressure response for this condition AND which of the following automatic actions would protect the RCS?
A. RCS temperature and pressure rising even with SDBCS valves and main spray valves opening; High Linear Power trip.
B. RCS temperature and pressure lowering due to SDBCS valves and main spray valves opening; Low RCS Pressure trip.
C. RCS temperature and pressure rising even with SDBCS valves and main spray valves opening; High RCS Pressure trip.
D. RCS temperature and pressure lowering due to SDBCS valves and main spray valves opening; Low DNBR trip.
Answer:
C. RCS temperature and pressure rising even with SDBCS valves and main spray valves opening; High RCS Pressure trip.
Notes:
The SDBCS capacity during normal ops is approximately 50% so they would not stabilize pressure and temperature alone initially. The spray valves response time would allow pressure to rise initially and spray valves have no affect on RCS temperature. So the initial response would be rising temperatures and pressure which would eventually decrease when decay heat levels drop after a Reactor Trip.
The rapid rise in RCS pressure would cause a High RCS pressure trip. Actual Linear Power should drop instead of rising so this would not trip the plant.

With Unit 2 at normal full power, the following Service Water alignment exists.
- Service Water Pump 2P4A is in Normal-after-Stop.
- Service Water Pump 2P4B running.
- Service Water Pump 2P4C running.
- All Service Water valves are in their normal full power lineup.
The following conditions now occur.
- A fault causes the non-vital 4160V bus 2A1 to lockout.
- Both Main Feedwater Pumps trip.
- The plant trips on Low SG levels.
- EFAS is automatically actuated.
- Assume no additional operator action is taken.
- All components and systems operate as designed.
What would be the status of the Service Water Pumps two (2) minutes after the plant trip AND what would be the status of Circulating Water Cooling Tower Makeup Valve 2CV-1540?
A. 2P4A and 2P4C running; 2CV1540 Closed.
B. 2P4A and 2P4C running; 2CV-1540 Open.
C. 2P4B and 2P4C running; 2CV-1540 Closed.
D. 2P4B and 2P4C running; 2CV-1540 Open.
Answer:
B. 2P4A and 2P4C running; 2CV-1540 Open.
Notes:
All three Service Water pumps receive a start signal on an EFAS. However the B SW pump will trip on the 2A1 bus lockout and when the EDG re-energizes the 2A3 vital bus (power supply to the Red train SW Pumps),
the A SW pump will start first because of the shorter time delay (4.5 seconds verses 6.0 Seconds for B SW Pump). The B SW pump breaker looks at the A SW pump and if it is running, it will not start to prevent excessive load on the diesel. Service Water is the makeup supply to the Circulating Water Cooling Tower. The Makeup isolation valve has no auto close features and is normally open so it should remain open.

Which of the following statements best describes the purpose and function of Main Feedwater Reactor Trip Override (RTO) signal after a Reactor Trip?
A. To rapidly refill the SGs with cold water to ensure an adequate RCS heat sink.
B. To slowly add feedwater to the SG to limit thermal stresses to the feed rings.
C. To rapidly add feedwater to the SGs to prevent an EFAS actuation.
D. To slowly refill the SGs with feedwater to prevent overcooling the RCS.
Answer:
D. To slowly refill the SGs with feedwater to prevent overcooling the RCS.
Notes:
After a Reactor Trip an RTO signal is sent to the MFW regulating valve to ramp closed quickly and the MFW regulating bypass valves will ramp open slowly based on RCS Tave. The minimum bias to the bypass valves is clamped so that a minimum of 2.24% flow demand will slowly recover the Steam Generator level to prevent overcooling the RCS and loss of Pressurizer level. The feedwater being added to the SG is still relatively warm so there is no concern with shocking the SG feed rings. The feed water is slowly added so distracters A and C are incorrect.

F Question:
Given the following;
- A Primary to Secondary leak has occurred on Unit 2 on the 'A' S/G.
- AOP 2203.038, Primary to Secondary Leakage, has been entered.
- The AO has been directed to complete Attachment 19, Control of Secondary Contamination.
Which ONE (1) of the following actions will be performed by Standard Attachment 19 to prevent an inadvertent radiological release?
A. Isolating the Unit 1 Oily Water Separator discharge.
B. Securing the Turbine Building Sump pumps.
C. Verify the Condensate Inlet Filter 2F-807 is in service.
D. Verify SG sample drains are aligned to the Hotwell.
Answer:
B. Securing the Turbine Building Sump pumps.
Notes:
Actions B is completed to reduce radiation exposure and control the spread of contamination after a Steam Generator Tube leak or rupture. Securing the sump pumps on the affected unit will prevent pumping any contaminated water to the Oily Water Separator. The Oily Water Separator serves both units so the unaffected unit will still need the Oily Water Separator to comply with environmental discharge limits. So the oily water separator will not be secured by Attachment 19 thus distracter A is wrong. Distracter C is wrong because 9 has the AO isolate and bypass 2F-807. Distracter D is wrong because Attachment 19 has the AO line up the SG samples to the neutralizing tank.

Given the following conditions: (Reference Provided)
- A down power in progress.
- During the initial few minutes of the down power, CEA Group 6 was used for ASI control and is currently 138" withdrawn.
- A decision was made to complete the down power using CEA Group P.
- Group P has been inserted to 132" and now will not respond to any move commands.
- The plant is currently at 85% power.
Which of the following actions would be required first based on the given conditions?
A. Immediately commence emergency boration due to loss of minimum SDM.
B. Continue the down power using CEA group 6 until less than 74% power.
C. Stop the down power and have I&C troubleshoot CEA group P control logic.
D. Commence logging time beyond the Long Term Steady State Insertion Limit.
Answer:
A. Immediately commence emergency boration due to loss of minimum SDM.
Notes:
The minimum COLR limit for SDM in Mode 1 is all CEAs above the transient insertion limit. If this is not true the Emergency Boration AOP requires Emergency Boration to be commenced until SDM is restored. At 84%
power, the transient insertion limit for CEA group P is 135 inches withdrawn.
Distracters B is incorrect because minimum SDM has been lost and restoration take priority.
Distracter C is incorrect because this action would be taken after Emergency Boration was commenced.
Distracter D is incorrect because the CEA groups have not entered the Long Term Steady State Insertion Limit area yet.
This question will require ANO-2 Technical Specifications, COLR Figure 3 to be given as a reference.

A. Enter Excess Steam Demand EOP 2202.005, after SPTAs, Actuate Main Steam Isolation Signal (MSIS); Steam Generator Pressures rising to required band.
B. Close Main Steam Isolation Valves (MSIVs) while in the SPTA Procedure 2202.001; Steam Generator Pressures rising to required band.
C. Enter RCS Overcooling Procedure AOP 2203.011 after SPTAs, then Close MSIVs; Steam Generator Pressures lowering to required band.
D. Actuate Main Steam Isolation Signal (MSIS) while in the SPTA Procedure 2202.001; Steam Generator Pressures lowering to required band.
Answer:
B. Close Main Steam Isolation Valves (MSIVs) while in the SPTA Procedure 2202.001; Steam Generator Pressures rising to required band.
Notes:
The MSIVs are directed to be closed first manually in the SPTA procedure if pressure is less than 950 psia and lowering. If the SG pressure continues to lower, then RCS overcooling may be diagnosed and entered to look for additional systems and components that could be causing an RCS cooldown. The RCS Overcooling AOP is written assuming Reactor already shutdown and an overcooling event occurs. If SG pressure drops below 751 psia then there is indication of an Excess Steam Demand in progress and the correct action would be to actuate MSIS and diagnose Excess Steam Demand Recovery procedure.

The 50.59 SCREENING for this PC indicates an intent change and a 50.59 EVALUATION must be completed.
Which of the following statements describes the correct action concerning the procedure change?
A. Approval can be granted as long as the OSRC, Onsite Safety Review Committee, reviews the 50.59 EVALUATION within fifteen (15) days.
B. Do not approve the change because a 50.59 EVALUATION is required prior to implementation.
C. Approval can be granted without completion of the 50.59 EVALUATION for intent changes.
D. Do not approve it because a special OSG, Onsite Safety Group, must be called for approval.
Answer:
B. Do not approve it because a 50.59 EVALUATION is required.
Notes:
A SRO cannot approve an interim procedure change if the 50.59 screening requires a 50.59 evaluation since the change could affect a license bases document and therefore requires more scrutiny, additional reviews, prior to implementation. A standard procedure change process must be implemented.

- Main Turbine load is 1044 MWth initially
- Annunciator 2K10 A2 "COLSS POWER MARGIN EXCEEDED" comes in.
- Plant power has risen to 101.7% power over the last three minutes and is rising
- Main Turbine load has lowered to 955 MWe over the last three minutes and is lowering.
Based on these conditions, which of the following is the correct action to take AND procedure to implement?
A. Lower plant power below 100% Immediately; Enter Excess Steam Demand EOP B. Lower plant power below 100% within 10 minutes; Enter RCS Overcooling AOP.
C. Initiate a Main Steam Isolation Signal; Enter Loss of Turbine Load AOP.
D. Direct Tripping the Reactor now ; Enter Standard Post Trip Actions EOP.
Answer:
D. Trip the Reactor; Enter Standard Post Trip Actions EOP.
Notes:
The correct action to take based on a steam leak at power is to reduce turbine load below 100%. If it is > 100%
but less than 101%, then a ten minute time frame applies. If grater than 101%, the action must be taken immediately. If the steam leak is large enough to cause a loss of > 50 MWt load to be removed from the main turbine, then this is trip criteria in the annunciator corrective action and SPTAs will be the guiding document.
Excess Steam Demand would not be entered until after SPTAs are complete. A Loss of Turbine Load AOP may be entered initially but it will not direct MSIS actuation.

The procedure directs lowering pressure to < 1265 psia to get > 40 gpm of HPSI flow to satisfy these conditions. The Emergency Boration AOP has a specific set of entry conditions:
ONE or MORE of the following conditions exist:
- 1. Reactor critical AND CEAs inserted below the Transient Insertion Limit (TS 3.1.3.6).
- 2. "REG GROUP CEA PDIL" annunciator (2K10-F1) in alarm.
- 3. Shutdown margin in Modes 3, 4, or 5 less than required per TS 3.1.1.1 or 3.1.1.2.
Thus this procedure would not be used to satisfy a safety function after SPTAs are completed.

The following plant conditions exist.
- Mode 6 with refueling shuffle complete.
- Personnel are currently in the A SG removing nozzle dams.
- RCS level is 19 inches and starts lowering.
- The running SDC Pump starts cavitating and becomes air bound.
- All attempts to restore SDC flow have failed.
- The running SDC pump has been secured.
What should be the controlling procedure for this event AND what action should be taken?
A. Lower Mode Functional; Start a BAM pump to make up to the RCS.
B. Lower Mode Functional; Commence a Containment evacuation.
C. Loss of Shutdown Cooling; Start the standby SDC pump.
D. Loss of Shutdown Cooling; Close the Charging RCS injection MOVs.
Answer:
B. Lower Mode Functional; Commence a Containment evacuation.
Notes:
No makeup should be added to the RCS with the SG manways open and people inside the SGs.
The SDC pump has become air bound due to vortexing in the pump suction. The Loss of SDC procedure would not restore flow to within 500 gpm of setpoint because the other pump would become air bound if started. The action to start the standby pumps calls for closing the LPSI injection MOVs first but this would not be the correct action to take since the pump cannot be started.
The Loss of SDC procedure may be entered first but will direct the SRO to exit to the Lower Mode Functional Recovery procedure.

Given the following:
- A Liquid Release Permit has been requested for Boric Acid Condensate Tank, 2T-69A.
- Chemistry has returned the permit to operations after sampling and analyzing the tank.
- While conducting the source check on the BMS Liquid Discharge Radiation Monitor, 2RE-2230 it is determined that the radiation monitor is not responding.
- 2RE-2230 has been declared inoperable.
To prevent an accidental release of a non-permitted tank, the release of 2T-69A CANNOT continue with the above conditions unless:
A. The Plant Manager has approved the release with an inoperable radiation monitor in accordance with Offsite Dose Calculation Manual (ODCM) Specification L.2.1.1.
B. Independent verification of tank samples, release rate data, and lineup completed in accordance with Offsite Dose Calculation Manual (ODCM) Specification L.2.1.1.
C. The inoperable radiation monitor, 2RE-2230, is returned to an operable status in accordance with Technical Specification 3.11.1, Liquid Holdup Tanks.
D. Contingencies for analyzing grab samples every two (2) hours are established in accordance with Technical Specification 3.11.1, Liquid Holdup Tanks..
Answer:
B. Independent verification of tank samples, release rate data, and lineup completed in accordance with Offsite Dose Calculation Manual (ODCM) Specification L.2.1.1.
Notes:
In accordance with the requirements in the Offsite Dose Calculation Manual (ODCM) Specification L2.1.1, a liquid release of an onsite tank can continue with an inoperable radiation monitor as long as an independent sample is taken and analyzed to ensure release limits will not be exceeded. Also an inoperable radiation monitor requires an independent check of the proper valve lineup to ensure the sampled tank is the one released. Plant Manager approval is not required specifically for this case. His approval of plant procedures in general allows this exception. Grab samples during the release are not specified in the OCDM requirement nor the procedure.

- Average CET temperature is 587°F and rising.
- RVLMS level 8 and above indicate DRY.
- RCS Chemistry sample indicates 390 microcuries/gram specific Iodine-131
- Containment pressure is 27 psia and rising.
- No release has been detected outside Containment.
- Hydrogen concentration in Containment is < 1%.
- All safety systems actuated as designed.
Which one of the following would be the correct action to take AND the correct E-plan classification?
A. Remain in the LOCA Recovery procedure; Alert.
B. Remain in the LOCA Recovery procedure; Site Area Emergency C. Go to the Functional Recovery procedure; Site Area Emergency.
D. Go to the Functional Recovery procedure; Alert.
Answer:
C. Go to the Functional Recovery procedure; Site Area Emergency.
Notes:
The conditions do not meet the safety function status check for Core Heat Removal in the LOCA EOP; therefore the SRO should transition to the functional recovery procedure. There is indication of > 1% failed fuel/core damage along with > 10 degrees F superheat so EAL 1.3 or 2.3 apply. There is no indication of a challenged or failed Containment so EAL 1.7 (General Emergency would not apply).
This question will require OP 1903.010 procedure as a reference.

D. Purge the VCT with Hydrogen using the CVCS Procedure 2104.002, Attachment J, VCT Hydrogen Purge to the Vent Plenum.
Answer:
D. Purge the VCT with Hydrogen using the CVCS Procedure 2104.002, Attachment J, VCT Hydrogen Purge to the Vent Plenum.
Notes:
The candidate must realize that the entry conditions for the H2/O2 Concentration High AOP are not met and based on plant conditions, the SRO will need to get the VCT Hydrogen concentration up above the required operating concentration (95%) for future plant startup. Thus he should use the normal procedure attachment to purge the VCT with Hydrogen.

Technical Specification 3.4.4 states: "The pressurizer shall be OPERABLE with a water volume of
< 910 cubic feet (equivalent to = 82% of wide range indicated level) and both pressurizer proportional heater groups shall be OPERABLE.
Which One of the following is the T.S. basis for < 82% PZR level and maintaining proportional heaters operable?
A. < 82% PZR level ensures a steam bubble in the pressurizer to prevent solid RCS operations and proportional heaters need to be operable to maintain natural circulation conditions during Hot Standby with a loss of offsite power.
B. < 82% PZR level ensures a steam bubble in the pressurizer to prevent solid RCS operations and proportional heaters need to be operable to maintain adequate NPSH to the RCPs during power operations.
C. < 82% level to limit volume of high energy fluid released from the RCS during a LOCA and proportional heaters need to be operable to maintain natural circulation conditions during Hot Standby with a loss of offsite power.
D. < 82% level to limit volume of high energy fluid released from the RCS during a LOCA and proportional heaters need to be operable to maintain adequate NPSH to the RCPs during power operations.
Answer:
A. < 82% PZR level ensures a steam bubble in the pressurizer to prevent solid RCS operations and proportional heaters need to be operable to maintain natural circulation conditions during Hot Standby with a loss of offsite power.
Notes:
A steam bubble in the pressurizer ensures that the RCS is not a hydraulically solid system and is capable of accommodating pressure surges during operation.
The requirement that 150 KW of pressurizer proportional heaters per bank and their associated controls be capable of being supplied electrical power from an emergency bus provides assurance that these heaters can be energized during a loss-of-offsite power condition to maintain natural circulation at HOT STANDBY.

F Question:
Which of the following describes the method of maintaining component configuration control when responding to a SG tube leak event?
A. The CRS keeps a handwritten list of components placed out of position and enters them in the COOP Log as time allows during the event.
B. Complete valve lineups for the affected systems are required to be performed after the event.
C. The Primary to Secondary Leakage AOP, 2203.038, is reviewed by the CRS after the event to ensure any equipment operated is returned to normal or documented in the proper log.
D. The Primary to Secondary Leakage AOP, 2203.038, has proper restoration steps in it to return all manipulated components to a normal configuration.
Answer:
C. The Primary to Secondary Leakage AOP, 2203.038, is reviewed after the event to ensure any equipment operated is returned to normal or documented in the proper log.
Notes:
During normal plant evolutions, configuration control is maintained by the normal methods of COOP log, Tagging sheets, etc. However, during emergency situations, due to the importance of timely EOP/AOP execution, it is NOT OPS managements expectation that every component manipulation directed by EOP/AOP be documented in COOP log, Station log, etc.
However, to ensure that configuration control is regained at conclusion of an event, the EOP/AOP is reviewed step by step by the CRS to ensure that any equipment that was operated by procedure is returned to its required position or documented in its out of normal position. The normal configuration controls and emergency configuration controls are normally updated and reviewed by the CRS.

A. Emergency Feedwater Pump 2P7A.
Notes:
During maintenance on either EDG, the steam driven emergency feedwater pump will not be taken out of service for planned maintenance activities and will be treated as protected equipment. This is 2P-7A. This is in the TS basis for the 14 day extended EDG maintenance window. The SRO may think that the B train components need to be protected but 2P-7B is actually powered from the #1 EDG.

D. A Condition Report and RWP must be generated AFTER the entry to document the condition.
Answer:
D. A Condition Report and RWP must be generated AFTER the entry to document the condition.
Notes:
If an emergency entry is required, then the entry can occur without generation of an RWP if a RWP is generated after the fact and tracked with a Condition Report. This entry must be approved by the Plant Manager or Designee which makes distracter A wrong. Time is not available to get current surveys if a fire is occurring which makes distracter B wrong. The individuals access to the CAA would not be pulled based on the entry only on the amount of total dose he has for the reporting period which makes distracter C wrong.

Answer:
B. Terminate the release and secure the release lineup in accordance with OP 2104.022, Gaseous Radwaste System, Supplement 1 due to no flow indication.
Notes:
Flow indication is required during any Gas Decay Tank release. The Offsite Dose Calculation Manual allows a continued release of the tank without flow indication if flow is estimated once every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />; however, this is difficult to do and most releases do not last 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> so the Release permit procedure requires termination of the release if the flow indicating transmitter is lost. There is an indication of release flow on 2C-14 but is driven from the local transmitter so it would also be failed low.
