H Question:

The reactor trips from 100% power due to a Loss of Offsite Power. The control room operators immediately observe the following:

Main generator output breakers are open.

#3 Main Turbine stop valve is fully open.

#3 Main Turbine Control valve is 50% open.

Annunciator 2K02B-14 "Condenser Interlock" is in alarm.

The Steam Dump Bypass Control System (SDBCS) is functioning as designed.

What action is required to be performed in SPTA's and what is the reason for this action?

A. Close both Main Steam Isolation Valves to prevent the main turbine from overspeeding.

B. Close both Main Steam Bypass Valves to prevent exceeding the design flow of SDBCS.

C. Locally close all SDBCS valves to prevent exceeding the design flow of SDBCS.

D. Locally close 2CV-0400 and 2CV-0460 to prevent the main turbine from overspeeding.

Answer:

A. Close both Main Steam Isolation Valves (MSIV's) to prevent the main turbine from overspeeding.

Notes:

"A" is the correct answer because MSIV's will remain open for at least 30 minutes after a loss of offsite power.

With a loss of offsite power the turbine generator will no longer be slowed down by the grid and will overspeed.

"B" "C" and "D" are incorrect because SDBCS capacity is not a concern because the condenser interlock and the loss of instrument air will close all SDBCS valves. Closing 2CV-0400 and 2CV-0460 will reduce overall steam flow and cooldown, but does nothing to reduce steam flow thru the turbine. The Main Steam Bypass valves are normally closed at 100% power therefore they would not perform this action.

H Question:

Consider the following:

Unit 2 is at full power.

2K10-A4 "Pressurizer Relief Valve Open" is in alarm.

Pressurizer Code safety audio monitor on 2C-336-1 for 2PSV-4633 indicates elevated flow noise.

2K10-B4 " PZR RELIEF TAILPIPE TEMP HI" is in alarm.

Quench Tank 2T-42 level is off scale high.

Containment Temperature and humidity are rising.

Containment building pressure is 15.6 psia and rising.

RCS pressure is 2100 psia and lowering.

Given these conditions, the indicated pressurizer level would be ___________ and the pressurizer level control system would be ___________.

A. >60%; controlling letdown flow at 128 gpm.

B. >60%; controlling letdown flow at 28 gpm.

C. <60%; controlling letdown flow at 28 gpm.

D. <60%: controlling letdown flow at 128 gpm.

Answer:

A. >60%; controlling letdown flow at 128 gpm.

Notes:

"A" is the correct answer because with a PORV stuck open on the pressurizer level should be artificially elevated to saturated conditions in the PZR. Pressurizer level control system will see a high level and the controller will call for maximum letdown flow which is 128 gpm. "C" and "D" are incorrect because pressurizer level will not lower with a steam space leak even though RCS inventory is lost due to saturated system effects.

"B" is incorrect because PZR level controller signal will be putting out 100% demand signal which corresponds to 128 gpm letdown not 28 gpm which corresponds to 16.6% demand minimum letdown flow)

H Question:

Given the following plant conditions:

Five (5) minutes post trip from full power.

RCS pressure is 1260 psia and stable.

Pressurizer Level is 9% and rising slowly.

"A" and "B" S/G are 960 psia and stable.

Quench Tank Pressure, Temperature and Level are normal.

Containment Low Range Radiation Monitors read 850 to 900 mr/hr.

Containment High Range Area Radiation Monitors read 1.1 R/hr and 1.0 R/hr.

Containment Pressure is 19 psia.

Containment Temperature is 245 degrees F.

RCS Cold Leg Temperature is 545 degrees F.

RCS Hot Leg Temperature is 548 degrees F.

Determine the event in progress for the given conditions and RCS Margin to Saturation per SPTA's:

A. Small Break LOCA; MTS is not satisfied.

B. Excess Steam Demand Event; MTS is not satisfied.

C. Small Break LOCA; MTS is satisfied.

D. Excess Steam Demand Event; MTS is satisfied.

Answer:

A. Small Break LOCA; MTS is not satisfied Notes:

"A" is correct because conditions for a Small Break LOCA exist i.e. margin to saturation lowering loss of inventory in the RCS and containment radiation levels rising for both the high and low range radiation monitors. Margin to sat calculated is 25.47 degrees and the limit is greater than 30 degrees. Distracter "C" is plausible if Margin to saturation is calculated incorrectly. Distracters "B" and "D" are plausible because of the reduced steam header pressure and containment high range radiation monitor readings will rise in a steam line break inside containment do to temperature induced effects.

The following plant conditions exist:

A large break LOCA has occurred on Unit 2.

EOP 2202.003, Loss of Coolant Accident is being implemented.

SIAS has actuated and 2DG1 is running loaded with its output breaker closed.

Annunciator 2K08-D1 "2DG1 Potential Engine Failure" is in alarm.

2DG1 Service Water Outlet Valve 2CV-1503-1 is closed and cannot be opened.

The maximum time that 2DG1 may be run before damage may occur is ____, and it must be secured by placing the ____.

A. 3 minutes, Control Room Handswitch in "Pull to Lock" position.

B. 10 minutes, Local Engine Control switch to "Lockout" position.

C. 3 minutes, Local Engine Control switch to "Lockout" position.

D. 10 minutes, Control Room handswitch in "Pull to Lock" position.

Answer:

C. 3 minutes, Local Engine Control switch to "Lockout" position.

Notes:

The answer is a step in the EOP to ensure compliance with the operating procedure caution.

"C" is the correct answer because the D/G must be secured within 3 minutes and this can only be performed from the local engine control switch because of SIAS signal being present.

"A" is incorrect but plausible because the EDG is normally secured from the Control room handswitch but it is disabled during an SIAS.

"B" and "D" are plausible because a 10 minute for operating the EDG unloaded does exist in the normal operating procedure to prevent oil buildup in the exhaust manifold.

H Question:

Given:

Unit 2 is at 100% power.

2P36C Charging Pump is OOS for maintenance.

2P36B Charging Pump is in "AUTO".

2P36A Charging Pump is running and trips on low oil pressure.

If no operator action is taken, which of the following describes the final state of letdown?

A. Normal letdown flow will be automatically restored after 2P-36A starts.

B. Automatic isolation of Letdown to protect the RCS Charging header inlet nozzles.

C. Automatic isolation of Letdown to protect the Regenerative Heat Exchanger.

D. Letdown flow will be at minimum flow (28 gpm) due to 2P-36A trip.

Answer:

C. Automatic isolation of Letdown to protect the Regenerative Heat Exchanger.

Notes:

C. is the correct because the standby pump will not auto start until a PZR level deviation and letdown flow will isolate at 470 degrees without charging available. The subsequent high Letdown temperature would damage the regenerative heat exchanger if flow is allowed to continue.

Distracter A is incorrect because the flow controller will go to minimum but then Letdown Isolation Valve 2CV-4820-2 will close isolating letdown on a high temperature.

Distracter B is incorrect because the RHX is protected from high temperatures and the charging flow will be lost in this scenario.

Distracter D is incorrect because the flow controller will go to minimum not maximum but then Letdown Isolation Valve 2CV-4820-2 will close isolating letdown on a high temperature.

Given the following:

RCS level is currently 25 inches from the bottom of the hot leg.

LPSI pump "A" is in service providing SDC flow.

LPSI pump "B" is in standby.

LPSI pump amperage and flow rate start to oscillate.

Instrument air header pressure is 98 psig.

No operator actions have been taken.

AOP 2203.029 Loss of Shutdown Cooling AOP has been entered.

Which of the following describes the action(s) required to mitigate this event in accordance with OP 2203.029?

A. Start "B" LPSI Pump to raise total system flow and reduce amperage on the "A" LPSI pump.

B. Stop "A" LPSI Pump then start the "B" LPSI to restore total system flow back to normal.

C. Leave "A" LPSI running and close 3 LPSI Injection MOV's to lower Net Positive Suction Head.

D. Leave "A" LPSI running and throttle SDC FCV 2CV-5091 to stop vortexing at the pump suction.

Answer:

D. Leave "A" LPSI running and throttle SDC FCV 2CV-5091 to stop vortexing at the pump suction.

Notes:

"D" is the correct answer, with instrument air available closing 2CV-5091 will stop vortexing by reducing flow at low RCS levels.

"A" answer is plausible but incorrect because amperage reduction on the "A" pump will occur but the additional flow will induce more vortexing.

"B" is plausible but will not change system conditions and will only jeopardize the good standby pump. The symptoms are do to system conditions not pump conditions.

"C" is plausible because Net Positive suction will be affected but not lowered as stated in the question

The plant is at 100% power with the following conditions:

Pressurizer Pressure Controller 2PIC-4626A is selected in AUTO with a setpoint of 2200 psia.

The following alarm is received: 2K10 E6 "CNTRL CH 1 PRESSURE HI/LO".

Pressurizer Pressure Control Channel 2PT-4626A is failed low and is reading "0" psia.

Pressurizer Pressure Control Channel 2PT-4626B is reading "2200" psia.

Pressurizer level is verified to be 60%.

What action(s) are required to be taken for the above conditions, and what is the status of the Pressurizer Proportional Heaters BEFORE actions are taken?

A. Manually control PZR heaters and close spray valves to restore RCS pressure, Pressurizer Proportional heaters are FULL ON.

B. Manually control PZR heaters and open spray valves to restore RCS pressure, Pressurizer Proportional heaters are FULL OFF.

C. Position the Pressurizer Pressure Control selector switch 2HS4626 to the 'B' position, Pressurizer Proportional heaters are FULL OFF.

D. Position the Pressurizer Pressure Control selector switch 2HS4626 to the 'B' position, Pressurizer Proportional heaters are FULL ON.

Answer:

D. Position the Pressurizer Pressure Control selector switch 2HS4626 to the 'B' position, Pressurizer Proportional heaters are FULL ON.

Notes:

"D" is the correct answer because the AOP directs to select the unaffected channel and PZR proportional heaters will be full on at 25 psia below setpoint due to "A" control channel failure.

"A" and "B" are plausible but incorrect because the AOP will direct these actions but only if both control channels are failed.

"C" is plausible because the first half of the answer is a correct action but the heater will be full on not off.

Consider the following:

Unit 2 is at full power operation.

The Unit 2 Main Turbine Trips on low lube oil pressure.

Reactor Protection System FAILS to trip the reactor.

The following indications are on 2C-409 Diverse Scram Signal (DSS) Panel.

The 'A' channel pressurizer pressure transmitter (2PT-4600-1) for DSS reads 2447 psia.

The 'B' channel pressurizer pressure transmitter (2PT-4600-2) for DSS reads 2451 psia.

The 'C' channel pressurizer pressure transmitter (2PT-4600-3) for DSS reads 2449 psia.

The 'D' channel pressurizer pressure transmitter (2PT-4600-4) for DSS reads 2452 psia.

Assume that all other plant components and their systems function as designed.

How would these conditions affect Unit 2?

A. These conditions would cause only the 'A' CEA MG Set DSS output contactor to open and ALL rod bottom lights would be illuminated on 2C03.

B. These conditions would cause the 'A' and 'B' CEA MG Set DSS output contactors to open and ALL rod bottom lights would be illuminated on 2C03.

C. These conditions would not cause MG Set DSS output contactors to open and NO rod bottom lights would be illuminated on 2C03.

D. These conditions would cause only the 'B' CEA MG Set DSS output contactor to open and only 50% of the rod bottom lights would be illuminated on 2C03.

Answer:

B. These conditions would cause the 'A' and 'B' CEA MG Set DSS output contactors to open and ALL rod bottom lights would be illuminated on 2C03.

Notes:

"B" is the correct answer because the DSS system uses a 2 out of 4 logic which will open a contactor on the output of the MG sets and cause all rod to drop to the bottom of the core illuminating dropped rod contacts on 2C03.

The DSS trip path logic comparators for channels 1 and 3 send a signal to DSS contactor #1 for MG set #1 and logic comparators for channels 2 and 4 send a signal to DSS contactor #2 for MG set #2. With a trip signal from channel 2 and 4 only. This makes answer "A" and "D" a plausible choice. Answer "C" could be chosen if confusion regarding "ANY 2 OUT OF 4 CHANNELS >2450 psia" vice two specific channels >2450 psia.

Unit 2 was manually tripped from 21% power due to Steam generator tube leakage greater than Tech Spec limits and the following conditions exist:

RCS pressure is 1975 psia and slowly rising.

PZR level is 35% and slowly rising.

2RE-5854 "A" S/G blowdown radmonitor reads = 400 cpm.

2RE-5864 "B" S/G blowdown radmonitor reads = 35 cpm.

RCS TAVE= 545 degrees.

Current tube leakage is 10 GPM and steady.

Based on the above condition, what actions should be performed to mitigate this event upon the completion of SPTA's?

A. Isolate the steam supply to 2P-7A from the "B" S/G.

B. Perform RCS cooldown to less than 535°F Thot.

C. Isolate the feedwater supply to the "B" S/G.

D. Perform RCS cooldown to less than 535°F Tcold.

Answer:

B. Perform RCS cooldown to less than 535°F Thot.

Notes:

"B" is the correct answer because neither an SIAS, Loop or leakage > 44 gpm have occurred therefore Primary to secondary leakage is the event in progress and cooldown to less than 535 °F is an appropriate action for this event.

"A" is incorrect but plausible because the "B" generator is not leaking but all other actions in the answer are correct.

"C" and "D" are plausible if it is not recognized that an SIAS, Loop or leakage > 44 gpm dont exist and "B" S/G is not the leaking generator.

A. Closed; CSAS..

B. Open; MSIS.

C. Closed; SIAS D. Open; EFAS.

Answer:

A. Closed; CSAS.

Notes:

"A" is correct because the feedwater block valve receive a closed signal on CSAS due to ANO Unit 2 power uprate/S/G replacement with larger generators. The CSAS signal closes the Main Feedwater Isolation Valves to limit containment pressure rise cause by feedwater flow to the affected S/G.

"B","C" and "D" are plausible because the valves do get an ESFAS signal during a steam line break but the candidate must know which direction the valves travel and which ESFAS signal.

Notes:

"A" is the correct answer because "A" Steam Generator is less than 22.2% and the normal suction source to EFW would be aligned because suction pressure is greater than 5 psig. The suction source aligned to the pump is the source of water to the bearing oil cooler.

"B" "C" and "D" are plausible because EFW has the ability to feed the "B" generator but the setpoint is too high and service water is an available suction source but not aligned at this time.

Given the following:

All 3 Service Water Pumps are running with 2P-4B aligned to Loop 2.

Unit 2 Reactor trips due to a Loss of Offsite Power.

All non-Vital and Vital AC buses deenergize.

2DG1 starts and energizes its associated vital 4160V bus.

2DG2 fails to start and cannot be started locally.

All associated equipment operates as designed.

Assume no operator actions.

How many Service Water Pumps are running and what loads are being supplied?

A. 1 Pump, Loop 1 Service Water.

B. 2 Pumps, Loop 1 Service Water.

C. 2 Pumps, Loop 1 Service Water and ACW.

D. 1 Pump, Loop 1 Service Water and ACW.

Answer:

A. 1 Pump, Loop 1 Service Water.

Notes:

"A" is correct based on not having any ESFAS actuations and only 1 service water pump aligned to the Red train - "A" service water pump will auto start when #1DG ties on to the 2A3 bus according to the stem "A" pump is only aligned to loop 1 service water.

"B","C" and "D" are incorrect because specify the wrong number of pumps running or the answer specifies that ACW will also be supplied. ACW is aligned to Loop 2, not Loop 1.

No Operator actions have been taken.

What is the response of the Service Water supply valves to the Component Cooling Water System (2CV-1530-1 and 2CV-1531-2) to the above stated conditions and what is the effect on the Service Water Pump discharge pressure?

A. The valves will be OPEN and a subsequent RAS will cause them to close; Service water pump discharge pressure will be LOWER than it was at 100% power.

B. The valves will be OPEN and a subsequent RAS will have no effect on them; Service water pump discharge pressure will be LOWER than it was at 100% power.

C. The valves will be CLOSED and can be overridden and opened, and a subsequent RAS will cause them to close; Service water pump discharge pressure will be HIGHER than it was at 100% power.

D. The valves will be CLOSED and can be overridden and opened, and a subsequent RAS will have no effect on them; Service water pump discharge pressure will be HIGHER than it was at 100% power.

Answer:

C. The valves will be CLOSED and can be overridden and opened, and a subsequent RAS will cause them to close; Service water pump discharge pressure will be HIGHER than it was at 100% power.

Notes:

"C" is the correct answer with a SIAS signal present these valves will close and increase service water system pressure.

"A" "B" are plausible if it is overlooked that a SIAS has occurred and the valve go closed/service water pump discharge pressure will actually be higher than it was at 100% power but lower than it should be with SIAS actuated.

"D" is the correct valve position but incorrect response/service water system response is correct.

The Control Room Supervisor declares Startup Channel #1 and Channel #2 Source Range Monitors inoperable.

The Reactor Engineer reports that 1/M plot data can no longer be obtained due to loss of Source Range Monitor data.

Which of the following describes the required action per OP 2102.016 Reactor Startup?

A. Reactor startup MAY continue provided boron samples are taken every 15 minutes.

B. Reactor plant startup MAY continue without the optional 1/M plot data.

C. Reactor startup MAY NOT continue because all log channel power has been lost.

D. Reactor startup MAY NOT continue, conservatively place the reactor in a safe condition.

Answer:

D. Reactor startup MAY NOTcontinue, conservatively place the reactor in a safe condition.

Notes:

"D" is correct based on guidance given in OP 2102.016 prejob brief and Limits and precaution 5.9 that states if unexpected conditions arise the reactor should be place in a safe condition.

"A","B" "C" are plausible but incorrect monitoring boron concentration is not a requirement if the start up channels are lost. All log channel power indication has not been lost the safety channels are still available. The procedure also gives no guidance to continue if 1/M plot data cannot be obtained therefore the operator should not continue.

A. The running 2VEF-8 "Auxiliary Building Radwaste Exhaust Fan" stops and "Waste Gas Decay Tanks Discharge Isolation" 2CV-2428 closes.

B. "Waste Gas Decay Tanks Discharge Isolation" 2CV-2428 automatically closes, The ventilation lineup is not affected.

C. The standby 2VEF-8 "Auxiliary Building Radwaste Exhaust Fan" starts and "Waste Gas Decay Tank Discharge Isolation" 2CV-2428 closes.

D. The running 2VEF-8 "Auxiliary Building Radwaste Exhaust Fan" and 2VSF-7A/B "Auxiliary Building Supply Fans" stop.

Answer:

B. "Waste Gas Decay Tanks Discharge Isolation" 2CV-2428 automatically closes, The ventilation lineup is not affected..

Notes:

2CV-2428 is the release path isolation and is interlocked to close if 2RITS-2429 "Gaseous Radwaste Discharge Rad Monitor" is in High alarm. No ventilation lineup changes occur as a result of a high radiation alarm. 2VEF-8A fans are interlocked with 2CV-2428 causing it to closed if they are stopped. 2VEF -8A/B are interlocked such that if the running fans stops, 2CV-2428 will receive a closed signal. The 2VSF 7 A/B fans receive no signals from 2RITS-2429.

Annunciator 2K11-B10 "Area Radiation HI/LO" is in alarm.

2RITS-8902 on elevation 335' "2F3A/B LETDOWN FILTER AREA" is in alarm on 2C25.

VCT level is lowering.

Charging header flow = 44gpm.

The online 2T20 tank level is rising.

Pressurizer level is 60% and stable.

Based on the above indications, what is the required action per AOP 2203.016, Excess RCS Leakage?

A. Isolate letdown flow by closing 2CV-4810/2CV-4811 backpressure control valves.

B. Secure all charging pumps to allow letdown flow to refill VCT to normal.

C. Isolate letdown flow by closing 2CV-4820-2 Letdown isolation valve.

D Secure all Charging pumps and close pump manual suction and discharge valves.

Answer:

C. Isolate letdown flow by closing 2CV-4820-2 Letdown isolation valve.

Notes:

"C" is correct based on the AOP actions for a leak in CVCS. The AOP directs the operator to isolate letdown flow by using 2CV-4820-2 if the leak is in CVCS. The operator should be able to determine the location of the leak by a combination of the radiation alarm, PZR level response, VCT level response, charging header flow and 2T20 tank level rising.

"A" "B" are plausible because they will result in restoration of VCT level but not isolation of the leak in both cases."D" are actions specified in the loss of charging AOP and are plausible if it is not recognized where the leak is located in the system.

A. 1.14 gpm B. 2.00 gpm C. 2.14 gpm D. 2.83 gpm Answer:

C. 2.14 gpm Notes:

The leakrate is proportional to the square root of differential pressure. The candidate has to remember this fact in order to correctly derive the answer.

The correct answer is 4 gpm times the square root of 10 divided by 35 = 2.14 gpm The other answers are a result of using a strait ratio or incorrect unit use.

F Question:

Which of the following sets of conditions indicates inadequate core cooling?

A. RCS pressure is 1100 psia; RCS Hot Leg and average CET Temperature are 532 °F; RVLMS LEVEL 2 and below indicates wet.

B. RCS pressure is 1200 psia; RCS Hot Leg and average CET Temperature are 582 °F; RVLMS LEVEL 7 and below indicates wet.

C. RCS pressure is 1350 psia; RCS Hot Leg and average CET Temperature are 577 °F; RVLMS LEVEL 3 and below indicates wet.

D. RCS pressure is 1450 psia; RCS Hot Leg and average CET Temperature are 590 °F; RVLMS LEVEL 6 and below indicates wet.

Answer:

B. RCS pressure is 1200 psia; RCS Hot Leg and average CET Temperature are 582 °F; RVLMS LEVEL 7 and below indicates wet.

Notes:

"B" is correct because based on the indications given the core is experiencing 14.81 degrees of superheat and water level in the core is below RVLMS LEVEL 6 therefore the core is uncovered.

"A" "C" and "D" are plausible because the temperatures and levels do not correspond to superheated conditions or core uncovery. The Steam tables need to be used to derive the correct answer without reference to the EOP.

During a natural circulation cooldown, which of the following pressurizer level responses would indicate the presence of a void in the reactor vessel upper head?

A. Pressurizer level rises when charging flow is directed through auxiliary spray.

B. Pressurizer level lowers when charging flow is directed through auxiliary spray.

C. Pressurizer level rises when charging flow is directed into the cold legs.

D. Pressurizer level lowers when there is an increase in the cooldown rate.

Answer:

A. Pressurizer level rises when charging flow is directed through auxiliary spray.

Notes:

Answer A is correct because a lowering of pressure in the pressurizer would cause expansion of the bubble in the head forcing water up into the pressurizer - just the opposite of answer B. Answer C is wrong because a level increase should be expected with charging going to the loops. Answer D is wrong because a cooldown should contract the RCS and lower Pressurizer level.

H Question:

Given the following:

Unit 2 Reactor has been manually tripped due to an RCS leak inside containment.

480V ESF Bus 2B5 sustains a lockout due to an electrical ground when the reactor is tripped.

SIAS,CCAS,CIAS have all actuated during SPTA's.

No operator actions have been taken.

Based on the above conditions, what is the status of the Chemical and Volume Control System (CVCS) and why?

A. BAM tank gravity feed valves are open (2CV-4920-1 and 2CV-4921-1) to supply borated water to the charging pump suction for VCT makeup.

B. RWT to the charging pump suction valve (2CV-4950-2) is open to supply borated water to the charging pump suction for RCS makeup.

C. BAM tank gravity feed valves, RWT to the charging pump suction and all BAM pumps are aligned to the charging pump suction for VCT makeup.

D. Both BAM pumps are running and Emergency borate valve (2CV-4916-2) is open supplying borated water to the charging pump suction for RCS makeup.

Answer:

D. Both BAM pumps are running and Emergency borate valve (2CV-4916-2) is open supplying borated water to the charging pump suction for RCS makeup.

Notes:

"D" is the correct answer because the BAM pump are the only available automatically aligned boration source due to the loss of power.

"A", "B" and "C" are plausible because these are all available boration methods but they are incorrect because they either do not automatically align (2CV-4950-2) or power has been lost (2CV-4920-1 and 2CV-4921-1) or a combination of both. VCT makeup will not occur because Letdown will isolate on SIAS (2CV-4820-2). Loss of 2B5 will deenergize 2B52 (2CV-4920-1 and 2CV-4921-1).

Given the following plant conditions:

The plant is at full power.

Pressurizer Level Control System master controller is in AUTO REMOTE.

Pressurizer Level Control 2HS-4628 is selected to Channel "B".

Pressurizer Heater Low Level Cutout 2HS-4642 is selected to Both "A & B".

Charging Pump Selector Switch 2HS-4868 is in "A & B".

Pressurizer Variable leg 2LT-4627-2 develops a large leak.

No operator action is taken.

WHICH ONE of the following describes the response of the Pressurizer Level Control System?

A. Charging Pumps A and B start, heaters energize, letdown flow rises.

B. Charging Pumps A and B start, heaters cutout, letdown flow lowers.

C. Charging Pumps B and C get a stop signal, heaters energize, letdown flow rises.

D. Charging Pumps A, B, and C get a stop signal, heaters cutout, letdown flow lowers.

Answer:

B. Charging Pumps A and B start, heaters cutout, letdown flow lowers.

Notes:

The Variable leg leak will cause a low indicated level input to the Pressurizer Level controller and associated bistables to cause level to indicate less than 29%. This will in turn send a start signal to the backup charging pumps in this case pumps A and B (the lead pump C will continue to run), a signal to deenergize all pressurizer heaters and force the Letdown Flow Controller to minimum output.

F Question:

The Loss of Shutdown Cooling AOP OP-2203.029 gives guidance to use a Containment Spray Pump per OP 2104.004 if both LPSI pumps are not available. OP 2104.004 prohibits use of the Containment Spray Pumps for Shutdown Cooling unless RCS suction pressure is < 50 psig.

What is the purpose of this pressure limitation?

A. To ensure insoluble gases do not collect in the Containment Spray discharge piping.

B. To ensure that cavitation does not occur in the Containment Spray pump casing.

C. To ensure that Containment Spray pump suction piping does not become overpressurized.

D. To ensure adequate D/P is developed across the pump for proper system flowrates.

Answer:

C. To ensure that Containment Spray pump suction piping does not become overpressurized.

Notes:

C is the correct answer to prevent overpressurizing the pump suction piping.

"A" and "B" would be true if the pressure in the system was increased. Voiding is more likely to occur at low pressures.

"D" is incorrect because the system pressure is felt on the suction and discharge equally therefore has no effect.

Which one of the following RPS trips will protect the fuel cladding by ensuring that the cladding heat transfer coefficient is large enough so that the maximum clad surface temperature is only slightly greater than the coolant saturation temperature during power operations?

A. Low Pressurizer Pressure B. Low DNBR C. High LPD D. High Log Power Answer:

B. Low DNBR Notes:

"B" is the correct answer based on Tech Spec Bases definition.

"A","C", and "D" are all plausible answers because they are related to power which effects fuel temperature and pressure which effects boiling. All are also Reactor trips.

Given the following:

The plant was tripped due to an Excess Steam Demand.

MSIS is the only actuation in.

The CRS has directed the CBOT to perform OP 2202.010 Attachment 4 "MSIS Verification".

Post cooldown temperature and pressure are being maintained.

RCS pressure is 1725 psia

Containment pressure is 14.8 psia.

Containment temperature is 120°F.

Based on the above conditions, what is the status of 2VSF-1A Containment Cooler discovered while performing OP 2202.010 Attachment 4?

A. Chill Water supply and return valves (2CV-3852-1 and 2CV-3851-1) are CLOSED.

Service Water supply and return valves (2CV-1511-1 and 2CV-1519-1) are CLOSED.

Bypass Damper 2UCD-8203-1 is CLOSED/RESET.

B. Chill Water supply and return valves (2CV-3852-1 and 2CV-3851-1) are OPEN.

Service Water supply and return valves (2CV-1511-1 and 2CV-1519-1) are CLOSED.

Bypass Damper 2UCD-8203-1 is OPEN/DROPPED.

C. Chill Water supply and return valves (2CV-3852-1 and 2CV-3851-1) are OPEN.

Service Water supply and return valves (2CV-1511-1 and 2CV-1519-1) are OPEN.

Bypass Damper 2UCD-8203-1 is OPEN/DROPPED.

D. Chill Water supply and return valves (2CV-3852-1 and 2CV-3851-1) are OPEN.

Service Water supply and return valves (2CV-1511-1 and 2CV-1519-1) are OPEN.

Bypass Damper 2UCD-8203-1 is CLOSED/RESET.

Answer:

D. Chill Water supply and return valves (2CV-3852-1 and 2CV-3851-1) are OPEN.

Service Water supply and return valves (2CV-1511-1 and 2CV-1519-1) are OPEN Bypass Damper 2UCD-8203-1 is CLOSED/RESET.

Notes:

"D" is correct because based on having only an MSIS and no CIAS or CCAS. The fans are running in the normal mode with Service Water aligned.

"A","B" and "C" are plausible because all these component receive an ESFAS signal to reposition but based on only having an MSIS the bypass damper will be closed and the normal chillwater supply will be open Source:

An inadvertent CIAS actuation has occurred on Unit 2.

The CRS has entered AOP 2203.039 "Inadvertent CIAS".

CIAS has not been reset.

Containment temperature and pressure are rising.

What are the correct action(s) to take per AOP-2203.039 based on the above conditions?

A. Verify all containment cooling fans running and service water inlet and outlet valves open to the coolers.

B. Verify all CEDM cooling fans running and service water inlet and outlet valves open to the coolers.

C. Verify all containment cooling fans running and main chill water inlet and outlet valves open to the coolers.

D. Verify all CEDM cooling fans running and main chill water inlet and outlet valves open to the coolers.

Answer:

A. Verify all containment cooling fans running and service water inlet and outlet valves open to the coolers.

Notes:

"A" is correct because without CIAS being reset service water is the only cooling water source. The AOP directs aligning and verifying service water is aligned.

"B" "C" and "D" are plausible but incorrect. The CEDM coolers would provide some cooling to the Reactor head general area but have little effect on containment atmosphere. Chill water to both the containment coolers and the CEDM coolers will be isolated on the CIAS and not available. Service water is not supplied to the CEDM coolers only to the containment coolers.

Core cooling is being provided by the HPSI pumps taking a suction on the Containment Sump and Injecting into the core. Exhibit 2 shows the expected flow for given RCS pressure that is required for Inventory/Heat Removal. Distracter A is incorrect because the CS system provides the cooling for the Containment Sump but does not provide flow to cool the core. Also the CSAS verification attachment only checks valve/component positions. Distracter C is incorrect because the SIAS verification attachments only checks valve/component positions. Distracter D is incorrect because the LPSI pumps trip with a RAS therefore LPSI flow should be zero.

Containment pressure peaked at 28 psia and has lowered to 21.5 psia.

Containment temperature peaked at 165°F and has lowered to 121°F.

Which of the following is TRUE concerning the Containment Spray system?

A. Containment Spray termination criteria IS satisfied and the CSAS should be RESET and Spray pumps secured.

B. Containment Spray termination criteria IS NOT satisfied until the TSC determines the system is not required for Containment Iodine Removal.

C. Containment Spray termination criteria IS satisfied but one train should be left in service for decay heat removal after a RAS.

D. Containment Spray termination criteria IS NOT satisfied until Containment Pressure and Temperature are back within Mode 3 TS limits.

Answer:

A. Containment Spray termination criteria IS satisfied and the CSAS should be RESET and Spray pumps secured.

Notes:

During a LOCA continued CNTMT Spray operation may be desirable to reduce offsite doses from airborne iodine activity in Containment. The TSC will perform dose assessment around the site and give the control room notice when Containment Spray is no longer needed for Iodine removal. However, during an ESD event the iodine concentration is not a concern so as long as all the termination criteria is met, CSAS should be terminated and RESET if all the criteria is met. Distracter B and C are incorrect because the termination criteria listed is for a LOCA only. Distracter D is incorrect because the termination criteria for Containment temperature and pressure are met in the ESD EOP well above the TS LCO limits.

Given the following:

The plant is at full power in the middle of an operating cycle.

The Extraction Steam flow to the #1 FW HTR 2E-1A is lost.

What effect will this have on the RCS?

A. RCS temperature will LOWER; Reactor power will LOWER.

B. RCS temperature will LOWER; Reactor power will RISE.

C. RCS temperature will RISE; Reactor power will RISE.

D. RCS temperature will RISE; Reactor power will LOWER.

Answer:

B. RCS temperature will LOWER; Reactor power will RISE.

Notes:

The loss of reheating steam to the #1 FW heaters will lower Feedwater temperature entering the SG which will lower RCS average temperature which will cause an out surge from the pressurizer causing a drop in level.

The lower temperature will induce positive reactivity in the core with a negative MTC thus causing Reactor power to rise. This question is also tied to GFES Reactor Theory Chapter 8 Reactor Operational Physics, Objective 21. Distracter A and D are incorrect because Reactor power will rise. Distracter C and D are incorrect because RCS temperature will lower.

Consider the following:

The plant was tripped from 100% power due to a high energy release inside Containment.

RCS pressure is 1700 psia and lowering.

Containment Building pressure peaked at 28 psia and is slowly lowering.

Both SG pressures are 1000 psia and steady.

The FW Pump Preferred Trip Selector Switch is selected to "B" MFW Pump 2P-1B Assuming no operator action, which one of the following represents the current status of the Main Feedwater Pumps?

A. MFW Pump 2P-1A running at minimum speed; MFW Pump 2P-1B tripped.

B. MFW Pump 2P-1B running at minimum speed; MFW Pump 2P-1A tripped.

C. Both MFW Pumps running.

D. Both MFW pumps tripped.

Answer:

D. Both MFW pumps tripped.

Notes:

The preferred pump selector switch will trip the pump selected on a turbine trip which is tripped on a reactor trip and send the other MFW pump to minimum speed. However, a CSAS signal will trip both MFW pump when Containment Pressure goes above 23.3 psia to limit energy addition to the Containment should A Steam Line break be in progress. Distracter A, B and C are incorrect because Both MFW pumps will be tripped.

Given the following conditions:

A reactor trip was automatically initiated concurrent with a MSIS.

Both SG levels are 23% Narrow Range and slowly restoring.

RCS T-ave is 520°F.

The correct status of the following Main Feedwater System components would be: (REFERENCE PROVIDED)

A. Running Main Feedwater Pump at 3150 rpm, Main Feed Regulating Valves Open, Main Feed Regulating Bypass valves at approximately 50% open.

B. Running Main Feedwater Pump at 3150 rpm, Main Feed Regulating Valves Closed, Main Feed Regulating Bypass valves at approximately 19% open.

C. Main Feedwater Pumps at turning gear speed, Main Feed Regulating Valves Open, Main Feed Regulating Bypass valves at approximately 50% open.

D. Main Feedwater Pumps at turning gear speed, Main Feed Regulating Valves Closed, Main Feed Regulating Bypass valves at approximately 19% open.

Answer:

D. Main Feedwater Pumps at turning gear speed, Main Feed Regulating Valves Closed, Main Feed Regulating Bypass valves at approximately 19% open.

Notes:

The Main Feedwater Pumps will go to minimum speed of 3150 rpm on a reactor trip based on a RTO signal to the FWICS; however in this case both MSIVs should be closed due to an MSIS on Low SG pressure signal so no steam is available to the MFW turbine therefore they will slow down and go on the turning gear. This makes answers A and B wrong. The MFRV always closes on a trip due to RTO. The MFRV Bypass valve modulates based on a T-ave of 548.24 at ~19% open position to a T-ave of 552 at 50% open. With the given conditions, T-ave should place the bypass reg. valves at approximately 34 % open. This is based on a calculation of 4.12%

flow demand at 550 degrees F T-ave. Therefore Distracter C is wrong.

Emergency Feedwater (EFW) Pump 2P7A is out of service for maintenance.

A Loss of Offsite Power occurs.

Emergency Diesel Generator, 2DG1, trips on low lube oil pressure during start.

Steam Generator Pressures are 1080 psia and stable.

During SPTAs, the AAC Diesel generator is started and aligned to ESF Bus 2A3.

Both Steam Generator levels have lowered from 70% and have just reached 28%.

A. would automatically start and both SGs will be automatically fed.

B. would automatically start and both SGs must be manually fed.

C. must be manually started and both SGs must be manually fed.

D. must be manually started and both SGs will be automatically fed.

Answer:

C. must be manually started and both SGs must be manually fed.

Notes:

The Motor Driven EFW pump must see the normal feeder breaker power from offsite or emergency feeder breaker power from the EDG to receive an automatic start. Thus for the given conditions, 2P7B must be manually started. The EFW feed valves will not automatically open above the EFAS-1/EFAS-2 setpoint of 22.2% level so they will have to be manually opened to established feed flow for RCS decay heat removal.

Distracter A and B are incorrect because the pumps must be manually started. Distracters A and D are incorrect because the valves must be manually opened.

If the loads on bus 2D02 do NOT change, which one of the following statements describe the batterys discharge rate (expressed as AMP's) as the battery is expended?

A. The battery AMP's will be fairly constant until the design battery capacity is exhausted.

B. The battery AMP's will drop steadily until the design battery capacity is exhausted.

C. The battery AMP's will rise steadily until the design battery capacity is exhausted.

D. The battery AMP's will drop based on the square of the change in resistance until the design battery capacity is exhausted.

Answer:

C. The battery AMP's will rise steadily until the design battery capacity is exhausted.

Notes:

P= IE; As the battery discharges under a constant load, battery voltage will drop and current (battery amperage) will rise. Distracters A, B and D are incorrect because the Amps will rise over time as the voltage drop with a constant load.

Which of the following describes 4160V breaker operation if DC control power is lost?

A. Breakers will remain in their "as is" condition and operation would only be possible by local manual means.

B. Automatic breaker trips would remain operational but remote operation of breakers would not be possible.

C. Breakers would remain remotely operable but automatic trip functions would become inoperable.

D. Breakers would trip open and operation would not be possible by local means.

Answer:

A. Breakers will remain in their "as is" condition and operation would only be possible by local manual means.

Notes:

125 VDC power provides the motive power for remote breaker operations and permissives, and breaker bypass interlocks. This would prevent any remote manual operations and automatic breaker cycles. Thus Distracters B and C are incorrect. Distracter D is incorrect because tripping the breaker open would require 125 VDC power.

F Question:

Given the following plant conditions:

Plant has returned to 100% power from 70% power after recovery of a dropped CEA.

Annunciator 2K12-A1, LETDOWN RADIATION HI/LO has actuated.

CBOT is directed to monitor RCS Gross and Iodine activities on Letdown Radmonitor Recorder, 2RR-4806, on 2C-14.

If RCS Iodine 131 Activity has caused the alarm, then ___________________ should be suspected but if RCS Gross Activity has caused the alarm, then __________________ should be suspected.

A. RCS crud burst; Letdown filter damage B. Fuel cladding damage; RCS crud burst C. Letdown filter damage; Fuel cladding damage D. RCS crud burst; Fuel cladding damage Answer:

B. Fuel cladding damage; RCS crud burst Notes:

A rise in the radioactivity of RCS could be caused by crud released in the RCS or failure of the fuel cladding of the Reactor fuel assemblies. The Gross gamma indication is read out on 2RITS-4806A while the specific activity level can be read on 2RITS-4806B. The specific activity monitor 2RITS-4806B monitors the Letdown fluid for the presence of Iodine-131. Iodine-131 is a fission product that is released with relative ease from defective fuel assemblies. A rise in the gross activity only would be an indication of a crud burst.

The differential pressure across the Letdown radiation monitors is driven by the pressure drop across the Letdown filter. The only way Letdown filter damage could cause a rise in RCS activity is if it as located upstream of the radiation monitor. As such they are in parallel to the radiation monitors thus answers A and C are wrong. D is wrong because it is the reverse of the correct answer B.

D. ECP Contained water volume of 70 acre feet: ECP top temperature 101°F; ECP bottom temperature 100°F.

Notes:

The level in the ECP is greater than or equal to the T.S. minimum of 70 acre feet for the ECP operability. The average ECP temperature is required to be equal to 100 degrees or less and is determined by adding the top and bottom temperatures and dividing by 2.

B. Reduce Containment temperature to < 110°F to ensure proper Oxygen levels for Containment Entry per 2104.033 "Containment Atmosphere Control".

C. No action should be taken, all Containment limits are met for pressure, and temperature.

D. Reduce Containment pressure to ensure a cushion exists for potential loss of Main Chill water per 2104.033 "Containment Atmosphere Control".

Answer:

D. Reduce Containment pressure to ensure a cushion exists for potential loss of Main Chill water per 2104.033.

Notes:

Average CNTMT pressure should be maintained between 13.9 and 14.2 psia to ensure cushion exists for potential loss of chill water. Maintaining negative pressure in building is necessary to enable fresh air to be drawn into building. Fresh airflow into building required to maintain oxygen levels above minimum required for human occupancy. Distracter A is incorrect because no TS limits have been exceeded. Distracter B is incorrect because the temperature is not out of the limit range and lowering temperature to 110°F will have little effect on Oxygen levels. Distracter C is incorrect because Limit and Precaution 5.6 in NOP 2104.033, Containment Atmosphere Control, is not met.

Given the following:

The plant is in cold shutdown (Mode 5) with the Containment Purge System in operation.

The operation of the Containment Purge system is being monitored using 2RE-9820, Containment Purge SPING #5 Radiation Monitor, and 2RE-8233, Containment Purge Exhaust Radiation Monitor.

If Containment radiation levels were to rise above setpoint, which one of the following actions would occur?

A. 2RE-9820 stops the Containment Purge supply and exhaust fans.

B. 2RE-9820 closes the Containment Purge supply and exhaust isolation valves.

C. 2RE-8233 stops the Containment Purge supply and exhaust fans.

D. 2RE-8233 closes the Containment Purge supply and exhaust isolation valves.

Answer:

D. 2RE-8233 closes the Containment Purge supply and exhaust isolation valves.

Notes:

The 2RE-9820 SPING 5 monitors the purge exhaust flow for activity to predict off site dose during emergencies but does not provide any interlocks to the purge components. 2RE-8233 will isolate the purge system on a high radiation signal. Another pressure switch in the purge system senses pipe pressure and will secure the supply and exhaust fans after the isolations close. Distracters A and B are incorrect because this monitor does not send any interlock signals to the Purge components. Distracter C is incorrect because the radiation monitor does not send the signal to secure the supply and exhaust fans, only to close the isolations.

A. To keep the cable properly seated on the cable drum.

B. To prevent burning up the hoist motor.

C. To prevent damage to the fuel assemblies being moved.

D. To prevent damage to the hoist breaks.

Answer:

C. To prevent damage to the fuel assemblies being moved.

Notes:

The fuel being raised or lowered could come in contact with a mechanical component and the overloads protect the hoist cable from exceeding its design limits and potentially dropping a fuel assembly. Underloads could cause the cable on the hoist to come loose and allow the grapple on the fuel assembly to be disengaged and potentially drop a fuel assembly. Distracter A is incorrect because there is spring tension on the cable drum to retrieve the cable on a fuel lift but could potentially come off the cable drum during an underload if the spring is worn or not functioning. Distracter Band D are potential failures if the overload and underload interlocks do not function but the main reason for the over and under load interlocks is to protect the fuel assemblies from damage.

F Question:

Given the following:

Power ascension is in progress following a reactor trip at 275 EFPD.

Power has been stabilized at 80% power to calibrate Nuclear Instruments.

1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months after stabilization, plant power starts rising with no operator action.

Plant power stabilizes at 85% power with no operator action.

Which one of the following valves, if it failed full open, would cause this increase in power?

A. Turbine Bypass Valve 2CV-306.

B. Turbine Bypass Valve 2CV-303.

C. Downstream Atmosphere Dump Valve 2CV-301.

D. Upstream Atmosphere Dump Valve 2CV-1001.

Answer:

B. Turbine Bypass Valve 2CV-303.

Notes:

2CV-303 is the only steam dump with a capacity of 5% steam flow. The rest have a capacity of 11.5 % steam flow. The mechanism that cause positive reactivity to be added to the core causing the power rise is a negative Moderator Temperature Coefficient. The lowering SG pressure in a saturated system lowers the overall SG temperature and lowers RCS Tave which will add the positive reactivity. Distracter A is incorrect because of the capacity of 2CV-306 is 11.5% and the SG pressure will lower. Distracter C is incorrect because of the capacity of 2CV-301 is 11.5%. Distracter D is incorrect because of the capacity of 2CV-1001 is 11.5%; however it is normally isolated so it is really 0% capacity and the SG pressure will lower.

H Question:

Given the following:

The Main Turbine trips from 50% power during power ascension with MOL core conditions..

The Steam Dump and Bypass Control System responds to maintain Reactor power at 50% and 1000 psia SG pressure.

10 minutes later Condenser vacuum has trended from 2.0 inches HgA to 6.0 inches HgA and is degrading.

What effect will this have on Reactor power and the RCS?

A. Reactor power will rise and RCS pressure will lower.

B. Reactor power will lower and RCS pressure will lower.

C. Reactor power will rise and RCS pressure will rise.

D. Reactor power will lower and RCS pressure will rise.

Answer:

D. Reactor power will lower and RCS pressure will rise.

Notes:

Condenser vacuum rising above 5.75 inches HgA will cause the condenser Steam Dumps 2CV-0302, 0303, and 0306 to close causing a loss of steam flow thus a loss of reactor power due to a negative MTC. The loss of heat removal will cause a rise in RCS pressure and an insurge to the PZR causing level to rise. Distracters A, B, C are incorrect because they have a combination of parameters that will not occur in this scenario.

Fire protection header pressure dropped from an initial pressure of 145 psig.

Header pressure dropped to 105 psig and then rose and stabilized at 130 psig.

2C343 indicates a fire in the Cable Spreading Room.

Local reports determine that the fire is fully developed and severe.

Based on the above conditions, which one of the following lists the correct Fire Protection pump that should be running and correct action to take?

A. Motor Driven Fire Pump P-6A; Trip the plant and evacuate the Control Room.

B. Motor Driven Fire Pump P-6A; Commence a rapid plant shutdown in the Control Room.

C. Diesel Driven Fire Pump P-6B; Trip the plant and evacuate the Control Room.

D. Diesel Driven Fire Pump P-6B; Commence a rapid plant shutdown in the Control Room.

Answer:

A. Motor Driven Fire Pump P-6A; Trip the plant and evacuate the Control Room.

Notes:

The Motor driven Fire pump will start when header pressure drops to less than 110 psig but the diesel driven fire water pump will not start until header pressure drops below 90 psig. A fire in the cable spreading room requires a control room evacuation after tripping the plant IAW the Alternate Shutdown procedure. The cable spreading room is just below the control room floor. There are several other safety related areas that should a fire develop and become severe, then a rapid plant shutdown would be required. Distracters C and D are incorrect because the Diesel driven Fire Pump would not start. Distracters B and D are incorrect because the control room would be evacuated.

Given the following:

A plant power ascension is being performed after a plant trip five days ago.

Core life is at 426 EFPD and plant power is at 65%.

A continuous 10 gpm dilution is in progress to raise RCS temperature.

The Main Turbine is on the Load Limit Pot.

Main Turbine load needs to be raised to maintain TREF at RCS TAVE.

Which of the following is correct action to take to raise turbine load?

A. Secure dilution of the RCS, raise Turbine load, then recommence dilution to prevent adding positive reactivity to the core by two methods at once.

B. Raise Turbine load, secure dilution of the RCS until the effects of the turbine adjustment have been seen on core reactivity then recommence dilution.

C. Raise Turbine load without securing dilution because raising Turbine load is a negative reactivity addition method which is allowed with a positive reactivity addition.

D. Raise Turbine load without securing dilution because raising Turbine load in conjunction with RCS dilution is considered one method of positive reactivity addition.

Answer:

D. Raise Turbine load without securing dilution because raising Turbine load in conjunction with RCS dilution is considered one method of positive reactivity addition.

Notes:

Per COPD001, Operations Standards and Expectations, Step 5.4.1 D, raising turbine load and dilution are considered one method of positive reactivity addition thus distracter A is incorrect. Securing the dilution would be considered at beginning of life with a high fuel worth, but not at end of life conditions thus Distracter B is incorrect. Diluting the RCS overcomes the negative reactivity due to the power defect. Raising turbine load will tend to lower RCS temperature thus adding positive reactivity thus Distracter C is incorrect.. This site guidance is allowed per the reactivity plan used for the power ascension.

Which of the following describes the required order for isolation and tag out of a centrifugal pump, and the reason for this order?

A. The pump power supply is isolated first, then the pump discharge valve is closed before the suction valve. This is to prevent pump suction over pressurization if back leakage exists.

B. The pump power supply is isolated first, then the pump suction valve is closed before the discharge valve. This is to maintain lubrication of the pump seals.

C. The pump suction and discharge valves are closed first, in any order, and then the pump power supply is isolated. This is to prevent pump flow with the valves closed.

D. The pump power supply is isolated first, and then the suction and discharge valves are closed in any order. This will prevent the pump from starting during isolation.

Answer:

A. The pump power supply is isolated first, then the pump discharge valve is closed before the suction valve. This is to prevent pump suction over pressurization if back leakage exists.

Notes:

There is normally a design pressure change from the suction side of a pump and the discharge side of the pump.

Closing the suction first would allow system pressure from another running pump to be felt on the suction and could cause over pressurization of the suction to the pump. Distracter B is incorrect because the suction valve is closed before the discharge. Distracter C is incorrect because the pump is isolated prior to isolating the power supply which would potentially allow the pump to start after it is isolated damaging the pump. Distracter D is incorrect because the suction could potentially be closed first.

B. Unidentified Leakage Notes:

The correct answer is 6.9- (3.2 +1.3 +.08 +.03) = 2.29 gpm which exceeds the allowed 1 gpm unidentified leak rate. Distracter A is incorrect because all the identified leak rates add up to 4.61 gpm which is less than the allowed 10 gpm but could be > 10 gpm if all the leak rates were added to the total RCS leak rate. Distracter C is incorrect because the leak is 115.2 GPD which is less than the allowed 150 GPD through any one SG.

Distracter D is incorrect because there is no allowed Total SG leakage TS limit, only 150 GPD through any one SG; however the total SG leakage is > 150 GPD ((158.4 gpm).

General area dose rates in the Lower South Piping Penetration Room (LSPPR) are 1300 mr/hour.

The CRS has sent the CBOT down to assist the WCO to troubleshoot the SDC Flow Control Valve 2CV-5091 due to oscillating SDC flow.

Which one of the following list the correct Radiation Protection posting that should be placed in front of the LSPPR door and the correct access requirements to the LSPPR for the above stated conditions?

A. High Radiation Area; Continuous Radiation Protection coverage and door barricaded with a rope stanchion.

B. High Radiation Area; Periodic Radiation Protection coverage and door locked Closed.

C. Locked High Radiation Area; Continuous Radiation Protection coverage and door locked Closed.

D. Locked High Radiation Area; Periodic Radiation Protection coverage and door barricaded with a rope stanchion.

Answer:

C. Locked High Radiation Area; Continuous Radiation Protection coverage and door locked Closed.

Notes:

The dose rates for the general area exceed the definition of a Locked High Radiation Area and should be posted as such. Access requirement for areas > 1 Rem/Hr require continuous RP coverage and a locked barricade to prevent inadvertent entry into the area. Distracters A and B are incorrect because the area is above a high radiation area. Distracter D is incorrect because the door is not locked and the RP coverage is not continuous.

Given the following:

The Alternate Shutdown AOP 2203.014 is being implemented.

The Control Room has been evacuated.

Follow up actions are in progress.

Pressurizer level is 20% and lowering.

RCS pressure is 1790 psia and lowering.

Based on these conditions, which one of the following actions should be taken and what affect will this have on the applicable system?

A. Reactor Operator Two (RO-2) should locally start Charging Pump 2P36A at 2B52; defeats all the automatic starts and stops for 2P36A.

B. The Emergency Operator (EO) should locally start Charging Pump 2P36B at 2B62; defeats the low oil pressure trip for 2P36B.

C. Reactor Operator One (RO-1) should locally energize PZR heaters in the Lower South Electrical Penetration Room (LSEPR); defeats the low level cutout of the PZR heaters.

D. The Control Room Supervisor (CRS) should locally energize PZR heaters in the Upper South Electrical Penetration Room (USEPR); defeats the high pressure cutout of the PZR heaters.

Answer:

A. Reactor Operator Two (RO-2) should locally start Charging Pump 2P36A at 2B52; defeats all the trips for 2P36A.

Notes:

The Reactor Operators (RO-1 and RO-2) are dispatched to the inside of the Aux Building (Controlled Access Part) during an Alternate Shutdown (Location of 2B52 and 2B62). All of the CRS and EO actions are completed outside Controlled Access which is where the LSEPR is located. The RO-2 is the actual RO that will start and stop charging pumps as needed to restore RCS inventory. Distracter B is incorrect because the RO-2 performs this function and the charging pumps only have an alarm on low lube oil pressure - no trip.

Distracters C and D are incorrect because the proportional heaters will not energize due to the low level heater cutout in effect due to the low level in the PZR to prevent heater burnout.

Consider the following conditions.

The plant is at 100% power.

Component Cooling Water (CCW) Surge Tank levels are slowly rising.

The Loop II CCW Radiation Monitor alarm comes in.

Chemistry samples of Loop II CCW indicate short lived radionuclides.

Which of the following would be the correct location of the leak, the correct implementing procedure, and the correct action to take?

A. RCP Seal Cooler, RCP Emergencies AOP 2203.025, Remain at 100% power and isolate the affected RCP seal cooler heat exchanger.

B. RCP Motor Cooler, Excess RCS Leakage AOP 2203.016, Remain at 100% power and isolate the affected RCP motor cooler heat exchanger.

C. RCP Motor Cooler, RCP Emergencies AOP 2203.025, Complete a plant shutdown and isolate the affected RCP motor cooler heat exchanger.

D. RCP Seal Cooler, Excess RCS Leakage AOP 2203.016, Complete a plant shutdown and isolate the affected RCP seal cooler heat exchanger.

Answer:

D. RCP Seal Cooler, Excess RCS Leakage AOP 2203.016, Complete a plant shutdown and isolate the affected RCP seal cooler heat exchanger.

Notes:

Distracter A is a source of RCS fluid into the CCW system but the guidance for isolating the Seal leak is found in the Excess RCS leakage AOP and the plant cannot run without 4 RCPs and must be shutdown. Distracter B is possible if the candidate fails to remember that there is no RCS fluid interface with the motor cooler and the plant cannot run without 4 RCPs and must be shutdown. Distracter C is cooled by CCW but CCW cools the air entering the RCP motor not RCS fluid and the RCP Emergency AOP does not contain guidance for isolating the motor cooler.

Given the following at full power:

Service Water Pump 2P4B has completed a motor replacement outage.

The pump is coupled up and ready for an operability test.

2P4B has been started and aligned to Loop 2 and ACW.

2P4C has been secured and the handswitch is in Normal After Stop.

2P4B Service Water Strainer DP is reading 11 psid on PD-1432.

Loop 2 Service Water flow is reading 2040 gpm on 2FI-1402.

ACW flow is reading 6020 gpm on 2FI-1601.

Based on this, which of the following describes the requirements to test an inoperable service water pump and the status of operability of Loop 2 Service Water?

(REFERENCE PROVIDED)

A. Prior to the test, the CBOT should be stationed at the 2P4B Handswitch in case of loss of offsite power; After the test Loop 2 Service Water is inoperable.

B. Prior to the test, a dedicated operator should be stationed at the 2P4B Handswitch in case of loss of offsite power; After the test Loop 2 Service Water is operable.

C. Prior to the test, the CBOT should be stationed at the 2P4B Handswitch in case of loss of offsite power; After the test Loop 2 of Service Water is operable.

D. Prior to the test, a dedicated operator should be stationed at the 2P4B Handswitch in case of loss of offsite power; After the test Loop 2 of Service Water is inoperable.

Answer:

D. Prior to the test, a dedicated operator should be stationed at the 2P4B Handswitch in case of loss of offsite power; After the test Loop 2 Service Water is inoperable.

Notes:

A dedicated operator with no concurrent duties should be stationed at the 2P4B handswitch during the test so that on a Loss of Offsite power, the operator can place the inoperable pump in Pull to Lock so the operable pump logic is made up to automatically start. Based on Table 2 of Form 2104.029 A, the minimum operable loop two SW flow for 11 psid on the suction strainer is 8080 gpm. Based on the indications in the stem only 8060 gpm of flow is indicated at 11 psid on the suction strainer so the loop 2 is inoperable and the Loss of Service Water AOP should be referred to..

Provide Form 2104.029A as a reference.

Stator Cooling outlet temperature on 2TS-9779 is reading 175°F (79.4°C)

Annunciator 2K02 A-4 "GEN PROT CIRCUIT ENERGIZED" comes in.

Which one of the following procedures contains the mitigating actions for these conditions?

A. Loss of Turbine Load Abnormal Operating Procedure 2203.024.

B. Annunciator 2K02 Corrective Action Response Procedure 2203.012B.

C. Generator Stator Cooling Water Normal Operating Procedure 2106.004.

D. Natural Emergencies Abnormal Operating Procedure 2203.008.

Answer:

A. Loss of Turbine Load Abnormal Operating Procedure 2203.024.

Notes:

The Generator Protective Circuit alarm will come in with > 7807 amps on the Main Generator which is well within the capability curve but to get the alarm, the Stator Water temperature has to be above 77.5°C. These condition will cause a rapid Main Generator runback relay to energize and Turbine load will be lost.

The ACA for the Generator Protective Circuit alarm sends the SRO to the Loss of Turbine Load AOP to mitigate this condition by emergency borating and inserting CEAs to prevent a Reactor trip on high pressure.

Distracter B is incorrect because the ACA only give the cause of the alarm and then directs the SRO to the Loss of Turbine Load AOP. Distracter C is incorrect because the temperature is high due to the high current on the Main Generator. Distracter C is plausible because the normal operating procedure would be applicable if the SCW Temperature control valve was malfunctioning. Distracter D is incorrect because there are no mitigating actions for the runback in this procedure but is plausible because there are mitigating actions for the severe thunderstorms in this AOP.

D. Restore saturation margin until all indicators are above 30 °F.

Answer:

B. Continue the cooldown and refer to TS 3.3.3.6 Post-Accident Instrumentation.

Notes:

The flashing readout on the local indicator means the calculator is malfunctioning. Adequate MTS can be verified by using the SPDS computer point when in the EOP. 30 °F is required to maintain safety function.

Since >30 °F can be validated then no other actions are required. If a valid low MTS was in, the RCPs should be tripped due to a loss of NPSH. There are no abnormal conditions and all Safety Function Status Checks (SFSCs) are met so no rediagnoses is called for but SFSC would not be met if actual MTS was less than 30°F.

Restoration above 30°F MTS is not required because it is not actually below 30°F. T.S. 3.3.3.6 requires 1 channel of MTS to be operable so the TS should be referred to and not entered.

In this case, a MSIS was actuated at 750 psia in the 'A' SG. To address this event and maintain the safety functions within the limitations in the facility's license and amendments, the Functional Recovery procedure has to be implemented. EFAS actuated when the 'A' SG level went below 22.2% NR but since it is the broke SG and has the lowest pressure, EFW will not automatically feed the 'A' SG. Since SG 'B' level never went below 22.2%,

EFW will not automatically feed the 'B' SG.

Given the following plant conditions at full power:

Emergency Diesel Generator 2DG1 is out of service for maintenance.

An Inadvertent Containment Spray Actuation Signal (CSAS) has occurred.

An electrical bus 2A1 lockout alarm actuates on the plant trip.

2P-7A, Emergency Feedwater Pump 'A' overspeeds and trips when starting.

All other equipment operates as designed and no other abnormal conditions exist.

After completion of the Standard Post Trip Actions (SPTA's), which of the following implementing procedures should be diagnosed, and what is the correct Technical Specification that should be implemented?

A. 2202.006, Loss of Feedwater; T.S. 3.7.1.2 Emergency Feedwater System.

B. 2202.006, Loss of Feedwater; T.S. 3.0.3, LCO 3/4 Applicability.

C. 2202.010, Functional Recovery; T.S. 3.7.1.2 Emergency Feedwater System.

D. 2202.010, Functional Recovery; T.S. 3.0.3, LCO 3/4 Applicability.

Answer:

B. 2202.006, Loss of Feedwater; T.S. 3.0.3, LCO 3/4 Applicability.

Notes:

The entry conditions are met for a Loss of Main Feedwater EOP because: 1) the CSAS tripped the MFW pumps and closed the MFW Block and Main Steam Isolation valves. 2) The B EFW pump and AFW pump 2P75 are not available due to the loss of their power supply bus 2A1 and the 2DG1 and 3) the A EFW pump is not available due to an overspeed condition. The functional recovery procedure should not be diagnosed because there is only one event occurring for the given conditions above and the loss of power can be restored using the Loss of Feedwater EOP. T.S 3.0.3 should be implemented because there are no EFW pumps available to feed the Steam Generators. The EFW T.S 3.7.1.2 applied until 2P7A oversped and tripped. Both Containment Spray pumps will be placed in Pull to Lock in SPTAs which again would be T.S. 3.0.3 instead of T.S. 3.6.1.2. The MSIV T.S. does not apply because the MSIV are closed in their ESF position.

Given the following at 100% power:

Annunciator 2K10-G6/G7 "CNTRL CH 1/2 Level LO" comes in.

The ATC reports that PZR Level Indication 2LI 4627-1, 2LI 4627-2, and 2LI 4625 are all failed LOW.

Troubleshooting by I&C determines that none of the indications can be restored.

No other PZR level indication are available on SPDS, PMS or on 2C80.

Which one of the following actions should be taken?

A. Enter AOP 2203.028, PZR Systems Malfunction, Commence a plant down power and add 77.5 gallons of makeup to the RCS for every one degree reduction in Tave.

B. Trip the Reactor, Enter SPTAs EOP 2202.001, Verify three charging pumps are continuously operating with Letdown isolated, and cool the plant down to SDC entry conditions.

C. Enter AOP 2203.028, PZR Systems Malfunction, Trip the Reactor, Commence adding 2750 gallons of makeup to the RCS to maintain PZR level, then GO to SPTAs EOP 2202.001.

D. Enter AOP 2203.028, PZR Systems Malfunction, place Letdown in manual control and match Charging and Letdown flows while maintaining 100% stable power.

Answer:

C. Enter AOP 2203.028, PZR Systems Malfunction, Trip the Reactor, Commence adding 2750 gallons of makeup to the RCS to maintain PZR level, then GO to SPTAs EOP 2202.001.

Notes:

As directed by AOP 2203.028, Answer C is the correct sequence to take. Distracter A is incorrect because there are no indications of PZR level and the Reactor should be tripped instead of shutdown but is plausible because the addition rate would maintain PZR level. Distracter B is incorrect as this would maintain RCS inventory but would tend to overfill the PZR and could cause RCS solid conditions. Distracter D is incorrect because there are no available PZR indications but would be correct if at least 1 PZR level indication could be read.

The plant is at 100% power when the 'B' Circ Water Pump Trips

The breaker for the B' Circ Water Pump Discharge Valve, 2CV-1215 trips open as the valve begins to close.

Condenser Vacuum is reading 6.6 inches of HG Absolute and rising rapidly.

Which of the following list the correct actions to take for these conditions?

A. Enter Loss of Condenser Vacuum AOP and commence Emergency Boration to lower power.

B. Trip the Main Turbine and go to Loss of Turbine Load AOP to stabilize Rx Power with ADVs.

C. Trip the Reactor, verify Main Turbine tripped, and go to Standard Post Trip Actions.

D. Enter Loss of Condenser Vacuum AOP, manually close 2CV-1215 and restore vacuum.

Answer:

C. Trip the Reactor, verify Main Turbine tripped, and go to Standard Post Trip Actions.

Notes:

Distracter A is a procedurally directed step (6) in the Loss of Condenser Vacuum AOP but it assumes the CW discharge valve on the pump that tripped went fully closed. If the valve does not close fully then the flow from the 'A' CW pump can be short-cycled causing a rapid loss of Condenser Vacuum (Step 4 of the Loss of Condenser Vacuum AOP). Distracter 2 is also a step in the Loss of Condenser Vacuum AOP (Step 5) but based on plant power and ADV capacity, reactor power cannot be stabilized before tripping on High RCS pressure.

Distracter D is incorrect as it would take to long for an operator to reach the discharge isolation at the cooling tower and manually close the valve but would be plausible for a slowly rising vacuum..

RCS pressure is 1400 psia and steady.

RCS Temperature is 548 degrees F and lowering

A current RCS sample reveals 47 µCi/gm of I-131 activity.

Dose Rate on RCS sample line 2TCD-19 indicates 400 mr/hr at 30 cm.

Low range containment radiation monitors are reading 10 R/hr.

High range containment radiation monitors are reading 12 R/hr.

Dose rate projection for the site boundary is unavailable at this time.

Distracter A would apply since RCS activity is greater than 37.8 µCi/gm I-131 but is incorrect since there is a SGTR with a steam release in progress (only way to cooldown without a condenser). Distracter B would also apply but with RCS activity than 37.8 µCi/gm I-131, EAL 3.4 would be the correct Eplan call. Distracter D is incorrect because the dose rate on 2TCD-19 are below the 1% failed fuel readings per 1903.010 Attachment 8 and there are no indications of inadequate core cooling.

Voltage for 2D01 on SPDS point E2D01 indicates zero (0) voltage.

The Reactor trips.

During SPTAs the voltage for 2D02 on SPDS point E2D02 goes to zero (0).

Which one of the following actions would be correct after completion of SPTAs?

A. Enter Loss of 125 VDC AOP and locally shutdown the PMS Inverter 2Y25.

B. Enter Loss of SPDS AOP and locally restart the SPDS Inverter 2Y26.

C. Enter the Functional Recovery EOP and locally shutdown the PMS Inverter 2Y25.

D. Enter the Station Blackout EOP and locally start the Alternate AC Diesel Generator.

Answer:

C. Enter the Functional Recovery EOP and locally shutdown the PMS Inverter 2Y25.

Notes:

On a loss off both 125 VDC vital buses 2D01 and 2D02, RPS may open all the Reactor Trip Circuit Breakers and trip the reactor. On a loss of a single 125 VDC bus, the Reactor may or may not trip and the correct action to take is to enter Loss of 125 VDC and take the action associated with the loss of the one bus that lost voltage.

In this case the reactor tripped and SPTAs should be completed. Then based on the Diagnostic flow chart, the functional recovery procedure should be entered based on loss of both Vital DC buses. Distracters A and B are incorrect because the reactor tripped and the AOP is no longer applicable.

Distracter D is incorrect because the wrong EOP is diagnosed but could be picked if the candidate realizes both safety bus voltages will also be zero since no EDG will start and Offsite power will not transfer power to the safety buses on a loss of vital DC.

A. During SPTAs, start the Alternate AC Diesel Generator (AACG) and tie to Bus 2A4.

B. Complete SPTAs, enter LOCA Recovery EOP and use Standard Att.11, Degraded Power.

C. Complete SPTAs, enter LOOP Recovery EOP and use Standard Att.11, Degraded Power.

D. During SPTAs, manually align Bus 2A2 to SU #2 Transformer and tie to Bus 2A4.

Answer:

B. Complete SPTAs, enter LOCA Recovery EOP and use Standard Att.11, Degraded Power.

Notes:

The RCS inventory safety function can be handled by one train (Red Train) of ESF equipment so there is no urgency to restore the Green train of ESF equipment in SPTAs. Distracter A is incorrect because SPTAs provide direction to start the AACG only if neither Emergency DG is available. In this case the Red Train 2DG1 is available. Distracter C is incorrect because there is no Loss of Offsite power and each specific recovery EOP has direction to restore power to a faulted bus. Distracter D is incorrect because the SPTA procedure has no guidance for this action and the LO Relay will prevent a manual transfer. Answer B is correct because step 19 of the LOCA recovery procedure Section 1 is a floating step and can be used anytime after completing SPTAs and entering the LOCA Recovery EOP to restore power to a faulted bus so this is the correct action to take.

Investigation reveals the Main Turbine load has dropped 16 MWe and is currently 1028 MWe and stable.

Plant power has risen to 101.5% power.

A. Lower plant power below 100% immediately based on ACA guidance for 2K10 A2.

B. Lower plant power below 100% within 10 minutes based on ACA guidance for 2K10 A2.

C. Enter Loss of Turbine Load AOP and restore Main Turbine load to 1044 MWe.

D. Immediately trip the Reactor and enter Standard Post Trip Actions EOP.

Answer:

A. Lower plant power below 100% immediately based on ACA guidance for 2K10 A2.

Notes:

Answer A is the correct action to take based on a steam leak at power to reduce turbine load below 100% if plant power exceeds 101%. The ACA directs this action but should be a known immediate action to the SRO who should direct this action prior to referring to the ACA. If it is > 100% but less than 101%, then a ten minute time frame applies. Distracter B is incorrect because plant power exceeded 101% Power. If greater than 101%, the action must be taken immediately. If the steam leak is large enough to cause a loss of > 50 MWe 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. Distracter D is incorrect because there has only been a loss of 21 Mwe. A Loss of Turbine Load AOP is plausible because the turbine is loosing load but Distracter C is incorrect because this AOP is for a Loss of Load and a loss in reactor power (rise in RCS temperature) and raising turbine load would raise Reactor power.

EOP 2202.001 SPTAs; open the cross-connect valves with Unit 1 to prevent a loss of IA on Unit 2 Answer:

A. AOP 2203.021, Loss of Instrument Air; close the cross-connect valves with Unit 1 to prevent a loss of IA on Unit 1 Notes:

With Unit 2 undergoing a Loss of Instrument Air event, under normal circumstances Unit 1 instrument air should be capable of supplying Unit 2. If a pipe rupture exists on Unit 2, it is possible that Unit 1 IA will not be able to supply both units. If Unit 1 (unaffected unit/IA supplier) IA pressure drops to less than 60 psig, the units IA should be split out as Unit 1 is now being threatened. The Loss Of IA AOP will be entered for these condition and tripping the plant and entering SPTAs is only directed in the AOP if IA header pressure on Unit 2 drops below 35 psig. Distracters C and D are incorrect because there is specific guidance on when to enter SPTAs (35 psig) and those conditions are not present. Distracters B and D are incorrect because the units normally have IA cross connected to supply the other in case of a leak/rupture.

H Question:

The following plant conditions exist at 15% power during a plant startup:

Annunciator 2K11 A-10, "SEC SYS RADIATION HI" comes in.

Condenser Offgas Radiation Monitor, 2RE-0645, has a high alarm.

"A" Steam Generator N-16 monitor indicates 3.2 gpd and rising.

"B" Steam Generator N-16 monitor indicates 300 gpd and rising.

Ten minutes later, the RCS leakrate is 50 gpm.

"A" Main Steam radiation monitor = 50 mR/hr and rising.

"B" Main Steam radiation monitor = 10 mR/hr and rising.

The plant is manually tripped.

Standard Post Trip Actions (SPTA's) are completed.

What is the status of "A" and "B" Steam Generators in the above stated conditions and which procedure should be implemented after SPTAs?

A. "A" SG is the ruptured SG and "B" SG is the intact SG; SG Tube Rupture EOP 2202.004.

B. "A" SG is the intact SG and "B" SG is the ruptured SG; SG Tube Rupture EOP 2202.004.

C. "A" SG is the intact SG and "B" SG is the leaking SG; Primary to Secondary Leakage AOP 2203.038.

D. "A" SG is the leaking SG and "B" SG is the intact SG; Primary to Secondary Leakage AOP 2203.038.

Answer:

A. "A" SG is the ruptured SG and "B" SG is the intact SG; SG Tube Rupture EOP 2202.004.

Notes:

In the ANO-2 EOP/AOP User guide, the words "Leaking SG" are used to define the SG primary to secondary leakage within the limits of OP 2203.038, Primary to Secondary Leakage. The words "Intact SG" are used to describe the SG with no tube leakage or the least affected by leakage. The words " ruptured SG are used to describe the SG with tube leakage in excess of the limits of OP 2203.038, Primary to Secondary Leakage, which is 44 gpm (See step 13 of AOP 2208.038) Also the N-16 SG activity monitors are not accurate below 20%

power and thus should not be used to diagnose SG leakage rates for the given conditions.

Distracter B is incorrect because the A SG is ruptured and B SG is the intact SG.

Distracter C is incorrect because the A SG is ruptured and the wrong procedure is implemented.

Distracter D is incorrect because the leakage is > 44 gpm (ruptured) which is considered ruptured not leaking and the wrong procedure is implemented.

Steam exhausting on the dry condenser tubes can cause thermally induced stresses therefore steam dumps that can exhaust on the dry tubes are disabled prior to isolating the waterbox. The suction isolations to the condenser vacuum pumps are also closed when isolating waterboxes to prevent overloading and tripping the vacuum pumps. Distracters C and D are incorrect because two Steam Dumps need to be disabled. Distracters B and C are incorrect because they have the wrong reason for disabling the steam dumps.

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

The power supply on the GDT Vent Line Radiation Monitor 2RITS-2429 has failed.

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 with no power available to 2RITS-2429.

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 flow path will only occur on a high radiation signal or the rad monitor failing high.

F Question:

Given the following:

Unit 2 has tripped from full power due to a Steam Generator Tube Rupture.

'A' Steam Generator has been diagnosed as the ruptured SG.

SG 'A' has been isolated.

RCPs 2P-32A and 2P-32D are running.

Cooldown and depressurization of the 'A' SG has commenced.

All other system and components function as designed.

During this time, the level in the ruptured SG should be maintained between ______________% and the basis for this level is to ensure SG tubes are ____________________.

A. 10 to 38; covered to prevent release of gaseous activity from the RCS.

B. 10 to 38; partially uncovered to cool the steam space of the 'A" SG.

C. 20 to 45; covered to prevent release of gaseous activity from the RCS.

D. 20 to 45; partially uncovered to cool the steam space of the 'A" SG.

Answer:

B. 10 to 38; partially uncovered to cool the steam space of the 'A" SG.

Notes:

Step 35 of the SGTR EOP has a step to maintain SG level 45 to 90% to limit any radioactive release. The basis for the 45% is to keep the SG tubes covered. However in Step 49 of the SGTR EOP, the process of cooling down the isolated SG begins and level is lowered to 10 to 38% to allow uncovering of the SG tubes thus transferring latent heat of the hot steam to the cooler RCS. C and D are incorrect because they list the wrong level to maintain. A and C are incorrect because they list the wrong basis.

H Question:

Given the following:

Both Units are operating at full power.

The NRC notifies the Shift Manager that an airliner attack has been validated and airliner arrival is expected in 20 minutes.

Which of the following is the correct Emergency Action Level (EAL) to implement and actions to take? (REFERENCE PROVIDED)

A. Notice of Unusual Event (NUE); Shelter all personnel in the CSB or LLRWB.

B. Alert; Shelter all personnel in the CSB or LLRWB.

C. Notice of Unusual Event (NUE); Evacuate all non essential site personnel.

D. Alert; Evacuate all non essential site personnel.

Answer:

B. Alert; Shelter all personnel in the CSB or LLRWB.

Notes:

Distracters C and D are incorrect because the procedure requires sheltering of personnel on such short notice in the Central Support Building or Low Level Rad Waste Building. Evacuations are the correct action if at least 30 minutes are available prior to the plane arrival time. Distracters A, C, and D are incorrect because they list the wrong implementing Emergency Action Level.
