Level RO SRO Question # 1 Tier #
1 Reactor Trip:
Group #
Knowledge ofthe reasons for the actions in the EOP KJA#
EPR007.EK3.Cll Importance Rating 4.0 4.6 Proposed Question:
The plant is initially at 100% power with RCS boron at 800 ppm, when the following sequence of events occurs:
- 1. The reactor trips.
- 2. Seven rods do not fully insert on the trip.
- 3. The crew enters ES-0.1, Reactor Trip Response.
- 5. The crew commences immediate boration per AOP 3566, Immediate Boration.
Why is the crew required to raise RCS boron concentration by 1300 ppm?
a) This ensures adequate SHUTDOWN MARGIN for any number of stuck rods, including all rods stuck out.
b) This is the assumed maximum boration achievable for the case where the R WST is the boration source.
c) This ensures the amount shutdown will be at least 1.3% following the outside design basis event ofmore than one stuck rod.
d) This ensures adequate SHUTDOWN MARGIN by borating 200 ppm for each stuck rod, minus 100 ppm for one assumed stuck rod.
Proposed Answer:
-:...;A:....-_
Explanation (Optional): Iftwo or more control rods are not fully inserted (or ifDRPI is lost), ES-0.1 will direct immediate boration due to shutdown margin concerns. The RNO directs the crew to immediate borate by 200 ppm for each rod not fully inserted ("D" plausible), up to either a maximum of 1300 ppm ("D" wrong, since 200 ppm x 7 rods = 1400 ppm), or an RCS boron concentration of 2600 ppm is reached. The 200 ppm per rod limit, OR the 1300 ppm total boration limit ensures SHUTDOWN MARGIN is met for any number of stuck rods including the all rods out configuration plus a 10% uncertainty ("A" correct). The 2600 ppm limit on RCS boron concentration ensures SHUTDOWN MARGIN is met for the design basis stuck rod condition, ensuring the amount shutdown to be at least 1.3% following the outside design basis event of more than one stuck rod (HC" wrong, but plausible), while ensuring the required boration can be accomplished when relying on the RWST as the boration source (liB" wrong, but plausible).

I Pressurizer Vapor Space Accident:
Group #
Ability to operate and/or monitor control ofPzr level KJA#
APE.008.AA1.06 Importance Rating 3.6
....;3:....:..6-=--___
Proposed Question:
The following sequence of events has occurred:
- 1. The "A" Pzr PORV spuriously opens, resulting in a safety injection.
- 2. When attempting to close the "A" PORV Block Valve, its breaker trips.
- 3. After exiting E-O, the crew is able to reenergize and close the "A" PORV block valve.
- 4. The crew terminates SI and restores letdown.
- 5. The crew enters FR-U, Response to High Pressurizer Level.
What actions will the crew take to regain control ofpressurizer level?
a) Tum on Pzr Heaters to generate steam in the Pressurizer, and control charging and letdown as necessary to maintain RCS pressure steady while Pzr level comes back into the desired band.
b) Tum on Pzr Heaters to generate steam in the Pressurizer, and commence venting the reactor vessel head to collapse any vessel head voids, lowering Pzr level back into the desired band.
c) Tum off all Pzr Heaters to minimize heat input to the RCS, and commence venting the reactor vessel head to collapse any vessel head voids, lowering Pzr level back into the desired band.
d)
Turn off all Pzr Heaters to minimize heat input to the RCS, and decrease charging flow to lower Pressurizer level to the desired band.
Proposed Answer:
A Explanation (Optional): At the onset ofthe vapor space break, RCS pressure rapidly dropped to saturation for the vessel head and hot legs. This causes two phase flow up the surge line into the Pzr, filling the pressurizer, with Pzr level remaining at 100% as long as the vapor space break is active. After the crew isolates the break and terminates SI, FR-1.1 will direct the crew to tum on Pzr heaters ("e" and "D" wrong) to add heat to the Pzr water, restoring saturation conditions, and generating steam in the Pzr. "C" and "D" are plausible, since all heaters are turned off in ES-1.2 during the cooldown/depressurization to minimize heat input. "B" and "c" plausible, since FR-I.3 vents the vessel head to remove a bubble in the head. "D" is also plausible since the normal means to lower Pzr level when it is on scale is to decrease charging. "A" is correct, and "B" wrong, since the crew is directed to control charging and letdown as necessary to maintain pressure stable while Pzr level lowers while a steam bubble forms. If there is no void in the head, pressure will increase as the steam bubble forms, requiring charging to be decreased or letdown to be increased. Ifthere is a void in the head, Pzr level will drop as the void collapses due to the pressure increase, requiring charging to be increased or letdown to be decreased.

With the plant initially at 100% power, the following sequence of events occurs:
- 1. A small-break LOCA occurs.
- 2. The crew enters AOP 3555, Reactor Coolant Leak.
- 3. The crew starts a second Charging Pump.

OPEN CLOSED Proposed Answer:
B Explanation (Optional): When SI actuates, 3CHS*LCVl12D opens, aligning the RWST to the Charging Pump Suction, then 3CHS*LCVl12B will close (" A" and "D" wrong) after 112D is open with SI actuated (or VCT level is less than 4%) to isolate the VCT from the Charging Pump. The cold leg injection valves will only open ifRCS pressure drops less than P-19 setpoint of 1900 psia ("C" wrong, "B" correct).

Question # 4 Tier #
Large Break LOCA: Knowledge ofthe interrelations Group #
between pumps and a large break LOCA KJA#
EPE.Oll.EK2.02 Importance Rating 2.6 2.7 Proposed Question:
A large, cold leg break LOCA occurs, and the RCS rapidly depressurizes to CTMT pressure.
What provides the actual motive force that drives ECCS water up into the active fuel region during the reflood phase ofthis accident?
a)
SI Accumulator head.
b)
Residual Heat Removal Pump head.
c)
Charging Pump head.
d) Vessel Downcomer water elevation head.
Proposed Answer:
---:::.D__
Explanation (Optional): Chapter 15 defines the reflood time as follows: The reflood phase ofthe transient is defined as the time period lasting from the end-of-refill until the reactor vessel has been filled with water to the extent that the core temperature rise has been terminated. From the later stage ofblow down and then the beginning-of-reflood, the safety injection accumulator tanks rapidly discharge borated cooling water into the RCS, contributing to the filling ofthe reactor vessel downcomer. The downcomer water elevation head provides the driving force required for the reflooding ofthe reactor core. The low head and high head safety injection pumps supply water to the RCS cold legs. Injection into the broken loop is lost out the break.
Injection into the other loops enters the vessel downcomer via the cold legs, and spills out the broken loop's cold leg ("A", "B", and "C" wrong), while maintaining the downcomer full, up to the bottom ofthe cold legs.
The water level in the downcomer provides a driving head due to elevation difference between its level and the level in the active fuel region ofthe core ("D" correct). "A" is plausible, since accumulators provide water for refill. "B" and "C" are plausible, since these pumps are injecting during a large break LOCA, and provide motive force on smaller breaks.

b) Failure ofRCP "A" #1 seal.
c)
Failure ofRCP "AI! #2 seal.
d)
Failure ofRCP "A" #3 seal.
Proposed Answer:
C Explanation (Optional): "An is wrong since isolation of seal injection results in RCS flow past the thermal barrier, maintaining seal flows. "A" is plausible, since sealleakoff flow has decreased. "B" is wrong, since
- 1 seal failure would result in HIGH #1 sealleakoffflow. HB" is plausible, since #1 Sealleakoffflow has changed, and would be correct if#1 sealleakoffhad also gone up. "c" is correct, since if#2 seal fails, flow through #2 will increase, and #1 sealleakoffwill decrease as more flow goes through #2 seaL "D" is wrong since failure of#3 seal will not affect operation of either the #1 or #2 seaL Its purpose is to limit gas release to CTMT. "D" is plausible, since a portion of#3 sealleakoffjoins #2 sealleakoff. This would be correct if

Ability to determine/interpret Charging Pump problems KJA#
APE.022.AA2.02 Importance Rating 3.2 Proposed Question:
The plant is at 100% power, and initial conditions are as follows:
The "C" Charging (CHS) Pump is running, aligned to the "A" Train.
The "A" Charging Pump Cooling (CCE) Pump is running.
The following sequence ofevents occurs:
- 1.
A fire breaks out in the Cable Spreading Room.
- 2.
The crew enters EOP 3509, Fire Emergency.
- 3.
Over the next several minutes, several spurious actuations occur.
- 4.
The "C" CHS Pump trips, and its MB3 Green and Amber lights illuminate.
- 5.
The crew enters EOP 3506, Loss ofAll Charging.
- 6.
The crew holds a brief, and determines the following abnormal conditions exist:
The "A" CCE Pump has TRIPPED.
The "B" "RHR TO CHG" Valve (3CHS*MV8468B) has spuriously CLOSED.
A PEO reports the "C" CHS Pump Breaker white "Auxiliary Circuit" light is OFF.
- 7.
All other equipment operates as designed.
What was the cause ofthe "C" CHS Pump trip?
a)
The pump overheated due to the loss ofthe "A" CCE Pump.
b) The pump cavitated due to an isolated suction flowpath.
c)
The pump breaker tripped due to a blown DC fuse on its 4KV breaker.
d) The pump breaker tripped due to a blown UT fuse on its 4KV breaker.
Proposed Answer:
B Explanation (Optional): This question is based on Millstone 3 OE, where a CHS Pump was started and damaged with an RHR TO CHG Valve closed. "B" is correct, since the CHS Pump suction from the VCT is sent to the "B" Train, and must pass through both cross-connect valves 3CHS*MV8468A and B (faikd closed) to reach the "A" train suction. "A" is wrong, since on a loss of running CCE pump ("A" plausible),
the standby pump will start on low pressure, and the CCE system cross-connect valves are open. "C" is wrong, since a blown DC fuse will de-energize the closing coil, but not cause the breaker to trip. "C" is plausible, since this fuse has blown, as indicated by the green and amber lights remaining lit, with the white aux circuit light no longer receiving power. "D" is wrong, since the DT fuse provides power to the MB indicating lights, which are still indicating. "D" is plausible, since a blown UT fuse will de-energize the trip coil, which would result in a CHS pump trip.

_4.:..:..:....3___
Proposed Question:
The plant is being cooled down in preparation for refueling after a 400 day run, and current conditions are as follows:
RCS temperature is 175°F RCS pressure is 305 PSIA The Pressurizer is solid.
Charging flow control is in manual RHR is in the cool down mode, with the"A" Train in service.
A tube in the "A" RHR heat exchanger suddenly fails, causing a 50-gpm tube leak.
Assuming no operator action is taken, what will be the result ofthe tube leak?
a) Actual RHR Pump flow will decrease and Pressurizer pressure will increase. RCS temperature will begin to increase.
b) Actual RHR Pump flow will decrease and Pressurizer pressure will increase. RCS temperature will begin to decrease.
c) Actual RHR Pump flow will increase and Pressurizer pressure will decrease. RCS temperature will begin to increase.
d) Actual RHR Pump flow will increase and Pressurizer pressure will decrease. RCS temperature will begin to decrease.
Proposed Answer:
--=.C__
RHR pressure is higher than CCP pressure; so 50 gpm is now flowing from RHR into RPCCW. With the tube leak, 50 gpm of flow that was sensed by RHR flow detector 3RHS*FT618 is now being lost into the RPCCW System. FT618 will see less flow and send a signal to 3RHS*FCV618 to throttle open to maintain 4000 gpm total flow, increasing actual RHR Pump flow ("A" and "B" wrong). "A" and "B" are plausible, since there is a leak between the RHR and RPCCW Systems, and the RHR total flow controller is responding to the transient. With Charging flow control valve 3CHS*FCVI21 in manual, 50 gpm is being lost from the RCS into RPCCW via RHR, so pressurizer pressure will decrease. Now a greater percentage ofRHR flow returning to the RCS is bypassing the RHS heat exchanger via FCV*618, so RCS temperature begins to increase ("C" correct, "D" wrong). "D" is plausible, since total flow through the RHR pump has increased.

Proposed Question:
With the plant at 100% power, the following sequence ofevents occurs:
I. The "A" RPCCW Pump trips.
- 2. The crew enters AOP 3561, Loss ofReactor Plant Component Cooling Water.
- 3. Prior to opening the procedure, the US directs the RO to isolate charging and letdown in order to stabilize the plant.
What actions will the RO take to complete this task?
a) Simultaneously CLOSE Charging Header Flow Control Valve 3CHS*FCV121 and the in-service Letdown Orifice Isolation Valve 3CHS* AV8149B or C. Then CLOSE Charging Isolation Valve 3CHS*MV8106.
b) Simultaneously CLOSE Charging Header Flow Control Yalve 3CHS*FCY121 and the in-service Letdown Orifice Isolation Valve 3CHS*AV8149B or C. Then CLOSE Letdown Isolation Valves 3RCS*LCY459 and 460.
c) CLOSE the in-service Letdown Orifice Isolation Valve3CHS*AV8149B or C. Then CLOSE Charging Header Flow Control Valve 3CHS*FCV121. Then CLOSE Charging Isolation Valve 3CHS*MV8106.

Proposed Answer:
A Explanation (Optional): Loss ofletdown cooling will cause the YCT to heatup, rapidly reaching foldout page RCP Trip Criterion, since VCT water is sent to the RCP seals. "A" is correct, since the RO will simultaneously CLOSE Charging Header Flow Control Valve 3CHS*FCV121 and the in-service Letdown Orifice Isolation Valve3CHS
- A V8147B or C, to minimize thermal stresses due to loss of Regen Heat Exchanger heating/cooling ("C" and "D" wrong). "C" and "D" are plausible, since this would remove the heat source for letdown prior to removing the cooling source to the Regen Heat Exchanger. Then Charging Isolation Valve 3CHS*MV8106 is CLOSED in order to isolate the charging path (FCV121 is a fail-open valve) ("B" wrong). "B" is plausible, since the Letdown Isolation Valves are in the letdown path, which is being isolated.

a) This ensures adequate seal injection and immediate boration flow, since CHS*HCV190B is undersized to supply both paths.
b) This prevents completely isolating the RCP Seal supply path from the "B" CHS pump.
c) This protects the "B" CHS Pump from damage by ensuring net positive suction head (NPSH) is maintained to the pump.
d) This protects against RCP Seal damage by preventing the Seal Inj1i:ction Filter from being bypass1ed.
Proposed Answer:
-,-,A:....,,--:-
Explanation (Optional): All charging flow will be aligned through HCV190B to prevent a problem with excess RCS inventory if FCV121 had failed open. "A" is correct since a separate seal supply path through 3CHS*V270 is aligned while charging through 3CHS*HCVI90B since it is undersized to supply both the charging and seal injection paths "B" is wrong since flow will not be isolated to the seals when MV8438B is closed, but plausible, since if the "B" train had lost power, all seal injection flow through the normal path would be isolated. "C" is wrong, since flow capability will be reduced when charging through HCVI90B, but plausible, since this is the basis for limiting charging flow while using the gravity borate path. "D" is wrong, since the seal injection filter is not bypassed in this alignment, but plausible, since an alternate charging and seal injection path are aligned.

EPE.038.GEN.2.2.37 safety related equipment Importance Rating 3.6 4.6 Proposed Question:
The following sequenee ofevents occurs:
- 1. A Steam Generator Tube Rupture occurs on the "B" SG.
- 2. Offsite power is lost on the trip.
- 3. The crew enters E-3, Steam Generator Tube Rupture.
- 4. The crew prepares to depressurize the RCS to minimize break flow and refill the pressurizer.
By what method is the crew required to depressurize the RCS, and why?
a) Depressurize the RCS using the Head Vent Letdown path, to prevent ereating a void in the Reactor Vessel Head.
b) Depressurize the RCS using the Normal Pressurizer Spray Valves, to minimize the loss of reactor coolant.
c) Depressurize the RCS using the Auxiliary Spray Valve, to provide a controlled depressurization rate.
d) Depressurize the RCS using a Pressurizer PORV, to minimize thermal stresses on the Pressurizer Spray Nozzle.
Proposed Answer:
D Explanation (Optional): "A" is wrong, sinee the crew will not be directed to depressurize the plant using the Head Vent path. "A" is plausible, since ES-O series procedures use the head vent path to protect against void growth, and the crew is cautioned in the E-3 depressurization step that void growth is possible during the depressurization. Also, the head vent letdown path will be aligned later in E-3 to restore letdown ifRPCCW is not available. "B" is wrong, since on a loss ofoffsite power, the RCPs have lost power, so there is no motive force for normal spray. "B" is plausible, since normal Pzr spray is preferred ifit is available, for the reasons given in "B", "C", and "D". Using a PORV can lead to adverse Ctmt conditions, loses RCS inventory, and is less controllable than normal pzr spray. "D" is correct, and "C" wrong, since at this point in E-3, letdown has not yet been restored to provide aux spray pre-heating, so thermal shock ofthe Aux Spray nozzle will occur if spray is initiated. A Pzr PORV is used instead of aux spray to minimize thermal stresses on the spray nozzle. "Cn is plausible since aux spray is preferred in ES-3.1, since by that time, letdown should be in service, and using Aux Spray does provide better control ofpressure and than a PORV.

APE.054.AKl.02 offeed introduction on a dry SO Importance Rating 3.6 4.2 Proposed Question:
With the plant initially at 100% power and the TDAFW pump tagged out, the following sequence of events occurs:
- 1. The "A" Feed Reg Valve fails closed.
- 2. The reactor trips on Lo-Lo level in the "A" SO.
- 3. Both MDAFW pumps auto-start.
- 4. The BOP reports AFW flow can NOT be established to the "A" SO, since MDAFW flow control valve to the "A" SO (3FW A *HIC31 AI) has failed closed.
- 5. The crew completes ES-O.l, Reactor Trip Response and transitions to FR-H.5, Response to Steam Generator Low Level.
Maintenance reports that the MDAFW flow control valve to the "A" SO has been repaired, and current conditions are as follows:
RCS Tave:
557°F Total AFW flow:
600 gpm "A" SO Wide Range level:
3%
In accordance with the WOO EOP Basis Document, what is the most significant operational concern ifthe crew reestablishes AFW flow to the "A" SO?
a) This will result in water-hammer that could damage the SO feed ring J-tubes.
h) This will result in thermal or mechanical shocks to the SO tubes that could rupture a SO U-tube.
c) This will reinitiate the cooldown, which could result in a Shutdown Margin concern.
d) This will reinitiate the cool down, which could result in a pressuriz(~d thermal shock (PTS) event.
Proposed Answer:
B
- --:-:--7:
Explanation (Optional): Feeding a hot (>550°F), dry (WR level <12%) will create significant thermal stresses on SO components. Reestablishing feed flow to a dry SO will result in thermal/mechanical shock to SO tubes, increasing the risk of either a tube leak or a tube rupture ("B" correct, "A", HC", and "D" wrong).
Therefore, FR-H.5 directs the crew to request the ADTS to evaluate refilling the affected SO as part oflong term recovery actions and transitions out ofFR-H.5, skipping the step to restore AFW flow. "A" is plausible since the feed ring will be uncovered on a hot, dry SO. Potential feed ring damage is not nearly as significant as a SO tube failure, which bypasses two ofthe three fission product barriers (Containment and the ReS).
"C" and "D" are plausible since increasing feedwater flow increases the cooldown rate and cooling down adds thennal stress to the RCS and also adds positive reactivity.

The plant has experienced a loss ofall AC power, and the operators are carrying out the actions ofECA-O.O, Loss ofAll AC Power.
An operator is dispatched to locally close RCP Seal Water Return Containment Isolation Valve 3CHS*MY8100.
Why is the crew directed to close this valve?
a)
Prevent thermal shock of RCP seals.
b)
Prevent the formation of steam in the RPCCW System.
c)
Prevent over-pressurizing the PRT, potentially releasing radioactivity in containment.
d)
Prevent overflowing the YCT, potentially releasing radioactivity in the Aux Building.
Proposed Answer:
-,,-D__
Explanation (Optional): Isolating at the RCP seal return line prevents seal leakage from filling the volume control tank (via YCT relief valve) with potential for radioactive release within the auxiliary building ("D" correct). Such a release, without auxiliary building ventilation available, could limit personnel access for local operations. "A" is wrong, but plausible since this is the reason for isolating seal injection during a loss of all AC. "B" is wrong, but plausible since this is the reason for isolating RPCCW to CTMT during a loss of all AC. "C" is wrong, but plausible since the PRT also receives radioactive vents, and has a rupture disk that relieves to CTMT.

Bleed and Feed has been initiated using only one PORV.
Compared to using both PORVs, how effective is Bleed and Feed cooling?
a) Cooling is LESS effective, since less RCS depressurization allows less subcooled SI flow.
b) Cooling is LESS effective, since more heat is initially transferred to the SOs, leading to more rapid SG dryout.
c) Cooling is MORE effective, since it will take longer for the Pressurizer to go solid, extending the time latent heat of vaporization assists in core heat removal.
d)
Cooling is MORE effective, since less RCS mass is lost through a single PORV.
Proposed Answer:
---,-,A__
Explanation (Optional): "A" is correct, and "C", and "0" wrong, since one open PZR PORV will lower RCS pressure at a slower rate than with two PORVs, during which time the RCS will continue to heat up. The PORVs will lower pressure only to saturation in the RCS, so pressure will not lower as far with the one PORV. So less injection flow will occur, and may not be sufficient to maintain adequate RCS feed flow. "B" is wrong, since heat transfer during bleed and feed is via the injection of cool ECCS water, and the removal of hot RCS water out the PORV(s). "B" is plausible, since less flow will enter the Pressurizer, and this is a basis for tripping RCPs in FR-H.l. This also relates to the basis the turbine is tripped in FR-S.l. "c" is plausible, since boiling does remove heat via latent heat ofvaporization, and it will take longer to go solid with only one PORVopen. "0" is plausible, since less mass is lost through one PORV than two, and this is a basis for using aux spray rather than POR V s to depressurize in the EOPs. Also, this relates to the basis for closing RCS vent paths in FR-C.l.

A Explanation (Optional): Since Frequency has not changed, turbine speed remains constant, since it is tied to the grid. The turbine control valves will remain steady, maintaining real load constant ("C" and "D" wrong).
A generator's MV AR load increases when generator terminal voltage increases above grid voltage. This can be caused either by raising excitation voltage, or by decreasing grid voltage, which has happened in the transient described in the stem ofthe question.

- 2. The RO reports one Control Bank D rod has not been inserting with the rest ofthe bank, and is misaligned by 14 steps.
- 3. The crew enters AOP 3552, Malfunction o/the Rod Drive System.
- 4. The US directs the RO to check Quadrant Power Tilt Ratio on the Plant Process Computer.
Does LCO 3.2.4 "Quadrant Power Tilt Ratio" apply at this power level; and based on flux tilt concerns, how long does the crew have to realign the rod before AOP 3552 will place additional restrictions on the mcovery ofthe rod?
a) LCO 3.2.4 does NOT apply, since power is below 85%. The crew has ONE hour to realign the rod.
b) LCO 3.2.4 does NOT apply, since power is below 85%. The crew has FOUR hours to realign th(~ rod.
c) LCO 3.2.4 DOES apply, since power is above 50%. The crew has ONE hour to realign the rod.
d) LCO 3.2.4 DOES apply, since power is above 50%. The crew has FOUR hours to realign the rod.
Proposed Answer:
~C__
Explanation (Optional): The QPTR LCO does not apply below 50% ("A" and "B" wrong). "A" and "B" are plausible, since 85% is the NIS Hi Flux setpoint that is required to be selected ifthe rod is misaligned for greater than an hour. "C" is correct, and "D" wrong, since AOP 3552 has the crew reduce power to less than 75% prior to rod recovery ifthe rod is misaligned for greater than an hour. This is based on industry OE (Arkansas Nuclear One, 1983), where fuel was damaged recovered due to flux peaking when a rod was realigned that had been misaligned for an extended period oftime. "D" is plausible, since four hours is the ACTION time to reduce the NIS Hi Flux setpoint with an inoperable rod.

APE.033.GEN.2.4.20 warnings, cautions, and notes Importance Rating 3.8 4.3 Proposed Question:
Initial Conditions:
- 1. A plant startup is in progress per OP 3203, Plant Startup.
- 2. Reactor power is 8%.
The IR HI FLUX ROD STOP annunciator is received on MB4C.
What failure may have caused this annunciator to come in, and what operational implications exist?
a) P-IO has cleared sooner than it should have. The crew will not be able to block the Intermediate Range Hi Flux Rod Stop when directed in OP 3203.
b) P-IO has cleared sooner than it should have. The crew will not be able to block the Intermediate Range Hi Flux Reactor Trip when directed in OP 3203.
c) An Intermediate Range NIS Channel is slowly failing high. The reactor will trip ifthe failed chalmel reaches the current equivalent of25% power.
d) An Intermediate Range NIS Channel is slowly failing high. The crew will need to block the Intetmediate Range Hi Flux Rod Stop before they can proceed with raising reactor power.
Proposed Answer:
--=C__
Explanation (Optional): In the note box in Attachment E of AOP 3571, Instrument Failure Response, this annunciator is listed as a symptom ofan IR Channel Failure. This annunciator is not received when P-I0 clears ("A" and "B" wrong). "C" is correct, and "0" wrong, since below P-l 0, the IR Rod Stop and IR Hi Flux Trip cannot be blocked. "D" is plausible, since the crew would normally block the Rod Stop when P-IO clears. "A" and "B" are plausible, since P-l°clears at 10% power, and it feeds into the bloek circuits for the IR Hi Flux Rod Stop, IR Hi Flux Trip, and the PR Hi Flux Lo Setpoint Reactor Trip.

APE.036.AAI.02 Importance Rating 3.1 3.5 Proposed Question:
The unit is in MODE 0, with the following evolutions in progress:
Fuel assemblies are being moved to different locations in the fuel pool.
A PEO is alternating in-service Fuel Pool Purification System (SFC) filters.
The following sequence ofevents occurs:
- 1.
A RADIATION HI annunciator is received on MB2.
- 2.
The RO reports 3HVR-RE17-1 (Fuel Building Exhaust) is in ALARM.
- 3.
The RO reports Area Radiation Monitor trends as follows:
3RMS-RE08-1 (Spent Fuel Pool Bridge Hoist Area) shows slightly increasing radiation levels.
3RMS-RE36-1 (Fuel Pool Area) shows slightly increasing radiation levels.
What is the most likely cause ofthe increasing radiation levels?
a)
Spent Fuel Pool level is decreasing.
b) Fuel Assemblies have been loaded into an unapproved loading pattern.
c)
The SFC System alignment is bypassing the SFC filters.
d)
A Fuel Assembly has been damaged during fuel movement.
Proposed Answer:
-'C-D__
Explanation (Optional): "At! is wrong, since a loss oflevel would show no increase on the ventilation monitor, since it is in the Auxiliary Building, and there is no release of radioactive material. "A" is plausible, since loss ofrefueling cavity/fuel pool level will reduce area shielding, causing an increase in area monitor radiation indication, and the SFC System is being manipulated. "B" is wrong, since re-arranging the fhe!
storage pattern would show no increase on the ventilation monitor, since it is in the Auxiliary Building, and there is no release ofradioactive material. "B" is plausible, since moving fuel in the reactor vessel affl!cts NIS detectors. Also, rearranging the fuel storage pattern could place fuel closer to a rad monitor, or affect Kerr in the pool. "C" is wrong, since bypassing fuel pool filters would take a fairly long time to increase fuel pool impurity levels. "c" is plausible, since a PEO is manipulating the SFC system, and bypassing the filters would cause an increase in radioactive particulate levels in the fuel pool. "D" is correct, since both ARMs and the PRM are showing increases, indicating increasing area rad levels locally due to gaseous release into the area, and also radioactive gasses entering into the ventilation exhaust.

EPE.WIEI4.EA2.2 procedures Importance Rating 3.3 3.8 Proposed Question:
An earthquake occurs, resulting in the following sequence of events:
- 1.
Safety Injection actuates due to four faulted SGs inside Containment.
- 2.
The BOP operator throttles total AFW flow to 550 gpm.
- 3.
The crew enters FR-Z.l, Response to High Containment Pressure.
- 4.
The crew reaches FR-Z.I, step 10, "Check If Auxiliary Feedwater Flow Should Continue to All SGs".
What action is the crew required to take with AFW flow?
a)
Stop AFW flow to all Steam Generators, to minimize the mass/energy release to CTMT.
b) Throttle AFW flow down to 100 gpm to each SG to minimize the mass/energy release to CTMT.
c)
Control AFW flow to stabilize RCS temperature while maintaining minimum heat sink requirements.
d) Maintain current AFW flow rate to maintain minimum heat sink requirements.
Proposed Answer:
B Explanation (Optional): The caution prior to step 10 states "Ifall SGs are faulted, at least 100 gpm feed flow should be maintained to each SG ("A" wrong)." "A" is plausible since, per step I 0 operators are required to isolate AFW flow to a faulted SG (but not with all four SGs being faulted). "B" is correct, and "C" and "D" wrong, since, per the caution, and the basis document, AFW is required to be throttled to 100 gpm to minimize the energy input to CTMT. "C" is plausible, since in other places in the EOP network, AFW flow is controlled to maintain hot leg temperature stable ifhot legs were heating up. liD" is plausible, since normally, AFW flow is desired to be maintained at greater than 530 gpm due to heat sink concerns.

EPE.WIE13.EK3.3 to obtain desired results Importance Rating 3.2 3.4 Proposed Question:
A turbine runback occurs, resulting in the following sequence of events:
I. The reactor trips.
- 2. The crew enters FR-H.2, Response to Steam Generator Overpressure.
- 4. Based on RCS hot leg WR temperature being> 530°F, FR-H.2 directs the crew to conduct a cool down by dumping steam from the unaffected SGs.
Why does FR-H.2 direct the crew to cool down the RCS from the unaffected SGs?
a) To reduce affected SG pressure, since excessive heat transfer from the primary may be the cause ofthe overpressure condition.
b) To reduce thermal stresses on the U-tubes ofthe affected SG, since excessive pressure stress already exists on the tubes.
c) To prevent a rapid depressurization ofthe RCS, since the affected SG may not be at saturation conditions.
d) To prevent a radiation release, since the cause ofthe overpressure condition may be a SG Tube Rupture.
Proposed Answer:
A Explanation (Optional): "A" is correct, and "B", "C", and "D" wrong, since excessive heat transfer from the primary may be the cause of the affected SG overpressurization. Therefore, a check on RCS hot leg temperatures is made. IfRCS hot leg temperatures are greater than or equal to 530°F (Which is the saturation temperature ofthe lowest steamline safety valve setpoint, including allowances for channel accuracy), a cooldown is initiated by dumping steam from the unaffected SG(s) to aid in reducing the temperature and pressure in the affected SG(s). "B" is plausible, since an overpressure condition exists. "C" is plausible, since this is a basis related to high pressurizer level in FR-L2, Response to High Pressurizer Level, and the SG may have a high pressure due to overfilling (but this would have led to an earlier transition to FR-H.3, Response to Steam Generator High Level. "D" is plausible, since this is a basis for cooling down the RCS if tube leakage is excessive.

Proposed Question:
With the plant initially at 100% power, the following sequence of events occurs:
- 1. The main turbine trips, causing a reactor trip.
- 2. The crew enters ES-O.l, Reactor Trip Response.
- 3. SIS actuates due to a fault on the "A" Steam Generator inside Containment.
- 4. The crew returns to E-O, Reactor Trip or Safety Injection.
- 5. Containment Hi Range Radiation Monitors 3RMS-RE04A and 05A start rapidly increasing.
- 6. Fuel Drop Radiation Monitors 3RMS-RE41 and RE42 show no change in radiation levels.
- 7. The Containment Status Tree changes color, indicating FR-Z.3, Response to High Containment Radiation Levels.
Is the crew required to transition to FR-Z.3? Why or why not?
a) The crew IS required to transition to FR-Z.3, since FR-Z.3 is a Yellow Path procedure, the crew has exited E-O, and no higher priority currently exists for the crew.
b) The crew IS required to transition to FR-Z.3, since FR-Z.3 is an Orange Path procedure.
c) The crew is NOT required to transition to FR-Z.3. The input to the status tree is 3RMS-RE41, which has not changed. The status tree is invalid.
d)
The crew is NOT required to transition to FR-Z.3. The 3RMS-RE04A105A readings are NOT valid for about 2 to 5 minutes due to Thermally Induced Current (TIC) effects.
Proposed Answer:
D Explanation (Optional): Containment Hi Range Radiation Monitors 3RMS-RE04A and 05A are susceptible to the effects of Thermally Induced Current (TIC), which are significant but of relatively short duration.
Generally, the effects of the TIC will dissipate within 2-5 minutes. "D" is correct, and "A" wrong, since until the TIC effects have dissipated, the RE04A1RE05A readings should not be considered valid. "A" is plausible, since FR-Z.3 is a Yellow path procedure, which is considered a supplementary set of actions provided to address individual parameters in an off-normal state, and the crew is in ES-O.l, with no significant events, such as SIS in progress. "B" is wrong, since FR-Z.3 is a YELLOW path procedure. "B" is plausible, since indicated increasing radiation has caused a status tree color change, FR-Z.2 is an Orange path procedure, and valid orange paths require transition. "C" is wrong, since the rad monitors that input to the status tree are the high range monitors. "C" is plausible, since a failed input to a status tree allows the crew to manually check the tree, and not make a transition if the status tree indication is found to be false.

A small break LOCA has occurred, and the operators are cooling down the plant per E8-1.2 Post-LOC'A Cooldown and Depressurization.
What RCP configuration is desired, and why?
a)
One RCP running for effective heat transfer and pressure control while minimizing heat input.

All RCPs stopped to minimize heat input into the Reactor Coolant System.
d)
All RCPs stopped to prevent possible core uncovery should a loss ofoffsite power occur.
Proposed Answer:
A Explanation (Optional): E8-1.2 background states that forced flow is the preferred mode ofoperation ("C" and "D" wrong) to allow for normal RCS cooldown and provide pressurizer spray ("A" correct and "B" wrong). All but one are stopped to minimize heat input to the RCS. "B" is plausible, since ECCS mixing is a basis for starting an RCP in FR-P.l. "C" is plausible, since this the basis for stopping RCPs in FR-H.l "D" is plausible, since this is a basis for RCP trip criteria, which do not apply once a controlled cooldown is commenced.

- 2. The RO opens RCP A Standpipe Fill Valve (3PGS-LCV181) at MB4.
How does RCP A standpipe level respond if no further operator action is taken, and how can the RO monitor standpipe level?
a) Level will increase until the standpipe high level setpoint is reached. The RO can monitor standpipe level on a meter on MB3.
b) Level will increase until the standpipe high level setpoint is reached. The RO can indirectly monitor standpipe level via a standpipe Hi/Lo level annunciator on MB4.
c) Level will increase until the standpipe overflows to the CDTT. The RO can monitor standpipe level on a meter on MB3.
d)
Level will increase until the standpipe overflows to the CDTT. The RO can indirectly monitor standpipe level via a standpipe Hi/Lo level annunciator on MB4.
Proposed Answer:
B Explanation (Optional): The standpipe fill valve will automatically close when the standpipe high level setpoint is reached ("C" and "D" wrong). "B" is correct, and "A" wrong, since the only way to monitor standpipe level in the control room is the high/low level alarms. "A" is plausible, since numerous RCP Seal injectionlleakoff indications are available on MB3. "C" and "D" are plausible, since ifthe standpipe overflows, it overflows to the CDTT.

- 2. The US enters the associated Annunciator Response Procedure.
To where is letdown currently routed; and what action will the ARP direct the crew take to mitigate the event?
a) Letdown flow is being directed to the CDTT. The RO will commence a manual makeup to the VeT.
b) Letdown flow is being directed to the CDTT. The RO will place 3CHS*PK131 in MANUAL and attempt to restore letdown header pressure to normal.
c) Letdown flow is being directed to the PRT. The RO will commence a manual makeup to the VCr.
d) Letdown flow is being directed to the PRT. The RO will place 3CHS*PK131 in MANUAL and a.ttempt to restore letdown header pressure to normal.

Explanation (Optional): Letdown Relief Valve 3CHS*RV8117 (600 psig lift setpoint) is lifting, directing letdown flow to the PRT (nAn and "B" wrong). "A" and "B" are plausible, since the Containment Drains Transfer Tank (CDTT) receives numerous drains inside CTMT. The ARP directs the crew to take manual control of3CHS*PK131 to open 3CHS*PCV131 to restore letdown flow and lower letdown header pressure

With the plant initially at 100% power, the following sequence ofevents occurs:
- 1. An inadvertent Train "B" Safety Injection Signal is received.
- 2. Train "A" Safety Injection Signal is NOT received.
- 3. The crew enters E-O Reactor Trip or Safety Injection.
Prior to operator action, what is the status ofsuction to the Charging Pumps; and what immediate action will E-O direct the operators to take to specifically address the current ECCS alignment?
a) Charging Pump suction is aligned to both the RWST and the VCT. The crew WILL NOT actuate SIS, to minimize the mass added to the RCS during this inadvertent SIS.
b) Charging Pump suction is aligned to both the RWST and the VCT. The crew WILL actuate SIS to establish a known ECCS system alignment prior to proceeding in the EOP network.
c) Charging Pump suction is aligned to the RWST, and isolated from the VCT. The crew WILL NOT actuate SIS, to minimize the mass added to the RCS during this inadvertent SIS.
d) Charging Pump suction is aligned to the RWST, and isolated from the VCT. The crew WILL actuate SIS to establish a known ECCS system alignment prior to proceeding in the EOP network.
Proposed Answer:
...-:;;;...D__
Explanation (Optional): On a Safety Injection, the Charging Pump Suction Valves from the RWST (3CHS*LCVl12D and E) open (Train-specific). Since these valves are in parallel, suction is aligned.
Charging Pump suction from the VCT isolates (3CHS*LCVI12B and C) isolate (Train-specific). Since these valves are in series, suction from the VCT has been isolated ("A" and "B" wrong). "A" and "B" are plausible, since pump suction is desirable, and only a single train of SI has actuated. liD" is correct, and "C" wrong, since ifonly a single train of SIS has actuated E-O directs the crew to actuate the second train of SIS. "C" is plausible, since the SIS is inadvertent, and a single train of SIS will add less mass to the RCS. This action was taken at Salem in response to the eel grass event, and the second train of SIS actuated later in the event.

007.Kl.Ol CTMT System Importance Rating 2.9 3.1 Proposed Question:
PLANT CONDITIONS:
- The plant is in MODE 3.
- The "A" PORV (3RCS*PCV455A) is leaking by and will not reseat.
- Block valve 3RCS*MV8000A will not close.
Assume Safety Injection docs not actuate, and no further operator action is taken.
To where will the excess water entering the PRT eventually be routed?
a) When the PRT Rupture Disk fails, the water will be released to the Containment atmosphere. It will then collect in the Unidentified Leakage Sump, and from there, be pumped to the Identified Leakage Sump, which is then pumped to Rad Waste.
b) When the PRT Rupture Disk fails, the water will be released to the Containment atmosphere. It will then collect in the Identified Leakage Sump, and from there, be pumped to the Unidentified Leakage Sump, which is then pumped to Boron Recovery.
c) When the PRT overfills, the water will automatically relieve to the Primary Drains Transfer Tank (PDTT). When the PDTT overfills, it will relieve to Rad Waste.
d)
When the PRT overfills, the water will automatically relieve to the Containment Drains Transfer Tank (CDIT). When the CDTT overfills, it will relieve to Boron Recovery.
Proposed Answer:
A Explanation (Optional): itA" is correct since the PRT is protected from overpressure by a rupture disk, which will rupture and release its contents to the containment atmosphere as it flashes to steam (HC" and "D" wrong.
As the steam condenses, it will collect on the CTMT walls and floor, draining into the unidentified leakage sump ("B" wrong, but plausible). From here, the water is pumped to the identified leakage sump, which is pumped to rad waste. "C" and "D" are plausible, since the CDTT and PDTT receive reactor plant gaseous drains from numerous sources, and their discharge can be routed to either rad waste or boron recovery.

007.K4.01 PRT cooling Importance Rating 2.6 2.9 Proposed Question:
Initial Conditions:
The plant is at 100% power.
Thc Primary Orade Water (POS) CTMT Isolation Valves are closed.
The following sequence of events occurs:
- 1. A discharge to the PRT occurs.
- 2. PRT temperature is high.
- 3. The US directs the RO to cool the PRT by filling it from POS using OP 330lA, Pressurizer ReliefTank and Reactor Vessel Flange Leakof[Operations.
In accordance with OP 3301A, what actions are required by the RO to commence cooling the PRT with POS water?
a) The RO must manually open the PRT Fill Valve at MB4, and POS flow will initiate, since the POS Containment Isolation Valves will have automatically opened.
b) The RO must manually open the POS Containment Isolation Valves at MBl, and manually open the PRT Fill Valve at MB4, initiating POS flow.
c) The RO must manually open the POS Containment Isolation Valves at MB 1, and POS flow will initiate, since the PRT Fill Valve will have automatically opened.
d)
The RO is required to monitor for proper valve operation, since both the POS Containment Isolation Valves and the PRT Fill Valve will have automatically opened, initiating POS flow.
Proposed Answer:
B Explanation (Optional): "B" is correct, and "A", "C", and "0" wrong, since all ofthese valves are manually opened and closed. "A", "C", and "0" are plausible, since the CIVs have an auto-close feature, and the PRT Vent Vale has an auto-close feature. Also, the PRT drain valve is interlocked with PRT level.

With the plant at 100% power and the Degassifier out of service, the following sequence of events oc(:urs:
- 1. The "LETDOWN HX OUT TEMP HI" annunciator is received on MB3A.
- 2. The RO reports RPCCW to Letdown Heat Exchanger Valve 3CCP-TCVl72 has failed CLOSED.
What will be the initial effect on the plant; and at what VCT temperature would the crew first be required to trip the plant?
a) Demineralizer Divert Valve 3CHS*TCV129 will automatically bypass the CHS demineralizers. The crew is required to trip the plant when VCT temperature exceeds 135°P.
b) Demineralizer Divert Valve 3CHS*TCV129 will automatically bypass the CHS demineralizers. The crew is required to trip the plant when VCT temperature exceeds 150°F.
c) Flashing will occur at the discharge ofthe in-service Letdown Orifice. The crew is required to trip the plant when VCT temperature exceeds 135°F.
d) Flashing will occur at the discharge ofthe in-service Letdown Orifice. The crew is required to trip the plant when VCT temperature exceeds 150°F.
Proposed Answer:
.......;...;A.......;...;_
Explanation (Optional): Loss ofRPCCW to the Letdown Heat Exchanger causes Letdown Temperature to increase, and when temperature increases to 134°P, letdown flow will bypass the demineralizers. The hotter water in the letdown stream will heatup the VCT water. This is a concern since this watcr is supplied to the RCP seals. The crew will receive a VCT high temperature annunciator, which will direct the crew to AOP 3561. AOP 3561 requires a plant trip if VCT temperature reaches 135°F ("A" correct, and "B" wrong). "B" is plausible, since the crew would not be required to trip the plant until VCT temperature exceeded 150°F if the RCS were less than 400°F, and this is also a trip criterion on the AOP 3561 Foldout Page. "C" and "D" are wrong, since the letdown orifice is upstream ofthe letdown heat exchanger, and the location vulnerable to flashing in the letdown stream on loss ofcooling to the letdown heat exchanger is downstream ofthe letdown heat exchanger, where temperature will be higher than nonna!, and pressure is at its lowest. "c" and "D" are plausible, since cooling has been lost to the letdown stream, and a pressure reduction occurs through the letdown orifice.

010.K1.08 and PZR LCS Importance Rating 3.2 3.5 Proposed Question:
With the plant initially at 100% power, the following sequence of events occurs:
A turbine ronback initiates.
- 2. During the ronback, both PZR spray valves start to throttle open.
- 3. As the ronback continues, the PZR backup heaters energize, even though spray valves are still open.
Why have the backup heaters energized?
A. The PZR level controller is responding to a greater than 5% outsurge from the downpower, to restore the PZR liquid to saturation conditions.
B. The PZR level controller is responding to a greater than 5% insurge from the downpower, to restore the PZR liquid to saturation conditions.
C. The PZR pressure controller is responding to the PZR pressurizer pressure rise via a rate/lag compensated circuit, to prevent pressure oscillations as pressure is restored to 2250 psia.
D. The PZR pressure controller is responding to the PZR pressurizer pressure drop via a rate/lag compensated circuit, to prevent pressure oscillations as pressure is restored to 2250 psia.
Proposed Answer:
-:;;;..B__
Explanation (Optional): The downpower will cause RCS temperature to increase due to a decrease in heat removaL This will cause RCS water to expand, resulting in a insurge to the pressurizer, so both PZR pressure and level will increase. The increase in pressure causes spray valves to open, and when pressurizer level increases by 5%, the heaters will energize (fiB" is correct, "Afl is wrong). The reason for this is that the temperature ofthe insurging water is not as hot as the pressurizer water, and ifan outsurge follows with the pressurizer water at less than saturation temperature, RCS pressure could rapidly drop. "A" is plausible, since pressurizer level is changing due to a heat imbalance between the primary and secondary plant. "C" and "D" are wrong since backup heaters cycle around 2225 to 2233 psia, and spray valves cycle around 2275 to 2325 psia, and shouldn't both be on together based on pressure. "C" and "D" are plausible, since pressurizer heaters are normally controlled by an input from pressurizer pressure.

The plant is initially at 100% power with all selectable controllers on the Main Boards selected to Channell.
The following initial sequence of events occurs:
I.
Pressurizer pressure instrument 3RCS*PI458 (Channel 4) fails HIGH.
- 2.
The crew enters AOP 3571, Instrument Failure Response.
- 3.
The crew completes all actions of AOP 3571, including tripping all bistables.
RCS Loop A Tave instrument 3RCS*TI412 (Channell) fails LOW due to its Tcold narrow range temperature instrument failing LOW.
Is the crew required to enter E-O, Reactor Trip or Safety Injection? If so, which reactor trip signal was received?
a)
The crew is not required to enter E-O. The reactor remains at power.
b) The crew will enter E-O, based on an OPAT reactor trip.
c)
The crew will enter E-O, based on an OT AT reactor trip.
d)
The crew will enter E-O, based on a high Pzr pressure reactor trip.
Proposed Answer:
--=C__
Explanation (Optional): The original pressure transmitter failure's corrective action required the crew to trip the OTDT bistable for loop "D", along with other bistables. When the Tcold channel fails low, DT fails high, bringing in an OTDT and OPDT bistable ("B" plausible) for channel I, meeting the 2 of4 coincidence for an OTDT trip ("C" correct, "A" wrong). "B" is wrong, since OPDT bistable was not tripped on a failed pressure instrument. "D" is wrong, since the high pressure trip requires 2 of4 bistables, and only one bistable is tripped. "A" is plausible, since two different types of instruments failed. "D" is plausible, since the original failure was a pressure channel.

The crew realigns Reactor Plant Chilled Water to supply the CAR Fans at Main Board 1.
How will the crew's actions affect Containment humidity; and where can the crew monitor Containment humidity in the control room?

c)
Humidity will decrease. This can be monitored on the dewpoint meter on MB2.
d) Humidity will decrease. This can be monitored on the dewpoint meter at VP 1.
Proposed Answer:
--=C__
Explanation (Optional): Each CAR fan draws air across the cooling coil assembly and discharges the air to a common duct which distributes it through secondary ducts to different levels of the containment. The crew has just realigned Reactor Plant Chilled Water (CDS) to the CAR fans, replacing RPCCW. Since CDS is colder (about 45°F) than RPCCW (about 85°F), this will increase CTMT cooling, decreasing CTMT temperature. Also, the colder (below the dewpoint) cooling coils will condense water vapor from the CTMT air as it passes over the coils, decreasing CTMT humidity ("A" and "B" wrong). Dewpoint meter 3LMS ME2lC indicates Containment humidity on MB2 ("C" correct, "D" wrong). "A" and "B" are plausible, since increasing cooling affects humidity. "D" is plausible, since VPl contains Ctmt Ventilation System Controls.

d) The pump starts as soon as the power is restored to bus 34C.

059.KL04 Steam Generator Water Level Control Importance Rating 3.4 3.4 Proposed Question:
With the plant initially at 100% power, Main Feedwater Header Pressure starts to decrease due to a significant feed header leak upstream ofthe feed flow venturis.
Prior to operator action, how will Feed Pump speeds and the Feed Regulating Valve positions initially respond to the decreasing pressure?
a) Feed Pump speed will INCREASE. SGWLC will throttle the Feed Regulating Valves in the OPEN direction.
b) Feed Pump speed will INCREASE. SGWLC will throttle the Feed Regulating Valves in the CLOSED direction.
c) Feed Pump speed will DECREASE. SGWLC will throttle the Feed Regulating Valves in the OPEN direction.
d) Feed Pump speed will DECREASE. SGWLC will throttle the Feed Regulating Valves in the CLOSED direction.
Proposed Answer:
A Explanation (Optional): As pressure drops, less feedwater enters the SGs. This causes a feed flow-steam flow mismatch, causing Feed Reg Valves to throttle open ("B" and "D" wrong). This further lowers feed pressure.
As the pressure sensed by 3FWS-PT508 decreases, the sensed DP between steam pressure and feed pressure decreases. The Master Speed controller increases pump speed to restore normal DP across the feed regulating valves ("AU correct, "C" wrong. Actual feed pressure will increase as the feed pumps speed up, increasing actual feed flow. After a lag, which allows for the effects ofshrink and swell to dissipated, the level error circuit will respond to tbe lower SG level (due to the initial decrease in feed flow) and also send a signal to open the feed regulating valves. "B", "C", and "D" are plausible, since the feed header pressure inputs to feed pump speed and SGWLC, and a transient is in progress.

c) The recire paths are directed to the DWST.
d) The reeire paths are directed to the suctions ofthe AFW pumps.
Proposed Answer:
C Explanation (Optional): "C" is correct, and "A", "B", and "D" wrong, since the AFW pump recirculation path is always aligned to the DWST via manual valves. This path is not ehanged when realigning suction to the CST. "A" is plausible, since the CST is the alternate, non-safety suction source. "B" is plausible, since the suction has been aligned to the CST. "D" is plausible, sinee numerous pumps, such as RHR pumps, have their recirc paths aligned back to their suctions.

With the plant operating at 100%, a "brown-out" condition on the grid results in MP3 bus voltages beiing supplied at 80% for 5 minutes.
How will the 6.9KV and 4.l6KV busses be affected?
a) All 6.9KV buses to remain energized at the low voltage. The normal 4.l6KV buses remain energized at the low voltage, while the emergency 4.l6KV buses are powered from the RSSTs.
b) All 6.9KV buses to remain energized at the low voltage. The normal 4.l6KV buses remain energized at the low voltage, while the emergency 4.l6KV buses are powered from the Emergency Diesels.
c) A1l6.9KV buses de-energize. The normal4.16KV buses de-energize, while the emergency 4.l6KV buses are powered from the RSSTs.
d) All 6.9KV buses de-energize. The normal 4.16KV buses de-energize, while the emergency 4.16KV buses are powered from the Emergency Diesels.
Proposed Answer:
-=B__
Explanation (Optional): The UV signal for the 6.9 KV buses is voltage less than 70% for 1.0 seconds, at which point the load breakers from the affected bus trip. Since voltage is at 80%, they will not de energize
("C" and "D" wrong, but plausible). Undervoltage to lockout NSST for the 4KV buses is also 70% so the NSST Supply breakers will not open. However, due to brownout conditions ( <90% voltage) without SIS or CDA present, after 4.5 minutes the 4160 V bus tie breakers will trip, the EDGs will start. If voltage on the emergency busses degrades to <30%, and RSST voltage is ~97%, the RSST supply breakers will attempt to close; but since RSST voltage is less than 97%, fast and slow transfer will not occur ("A" wrong, but plausible). With the RSST breaker failing to close, emergency bus voltage will drop to less than 30%, and after 5 more seconds, the EDG breakers will close to reenergize the bus ("B" correct).

While at 100% power, the following sequence of events occurs:
I.
Emergency bus 34D receives a Bus Differential and deenergizes.
- 2.
The crew enters AOP 3577, Loss ofNormal and OfJsite Power To A 4.16KV Emergency Bus.
- 3.
AOP 3577 directs the crew to shift the seal return flowpath to the top ofthe VCT.
What does shifting seal return to the top ofthe VCT prevent?
a)
An unmonitored heatup ofthe charging pump suction water, which is supplied to the RCP seals.
b) An uncontrolled pressure increase in the VCT due to loss of cooling to the Letdown Heat Exchanger.
c)
A heatup in the VCT, resulting in cavitation when a charging pump is subsequently started.
d)
A heatup in the VCT, resulting in decreased cooling to the CVCS Regenerative Heat Exchanger.
Proposed Answer:
A Explanation (Optional): "A" is correct, since seal return is normally directed to the suction ofthe charging pumps, and with the loss ofbus 34D, cooling is lost to the seal return HX. This results in hotter water flowing to the charging pump suction and to the RCP seals, with the inability to monitor actual seal injection temperature, which is normally monitored via VCT temperature. Directing return to the top ofthe VCT allows for monitoring seal injection temperature using 3CHS-TIl16 at MB3. "B" is wrong, but plausible, since a loss ofcooling to the letdown HX occurs with a loss ofbus 34C...c" and "D" are plausible, since switching the heated seal return to the top ofthe VCT will cause VCT to heatup faster, and VCT water is supplied to the Charging Pump suction and the Regenerative Heat Exchanger.

With the plant initially at 100% power, the following sequence ofevents occurs:
- 1. VIAC-l de-energizes.
- 2. On the resulting transient, the following events occur:
The reactor trips, Safety Injection actuates, Offsite power is lost.
- 3. The crew enters E-O, Reactor Trip or Safety Injection.
Without operator action, how will the "A" Emergency Diesel Generator (EDG) respond?
a) The nAn EOG will NOT automatically start. Bus 34C will remain de-energized.
b) The "A" EOG starts, but Bus 34C will NOT strip, and the EOG output breaker will NOT automatically close. Bus 34C will remain de-energized.
c) The "A" EDG starts, but Bus 34C will NOT strip. The EDG output breaker will automatically close onto a loaded Bus 34C.
d) The "AI! EDG starts, Bus 34C strips, and the EDG output breaker automatically closes onto Bus 34C.
But Bus 34C loads will NOT automatically sequence onto the bus.
Proposed Answer:
B Explanation (Optional): Loss ofVIAC-1 or 2 deenergizes the associated EDG sequencer. The loss of a sequencer with SIS actuating results in the following:
The associated diesel will not start (except LOP) ("A" wrong, since LOP occurred, but plausible, since the EDG would not start on SIS). With a de-energized sequencer, bus stripping will not occur (HC" plausible),
and the associated train's load sequencing will not occur (liD" plausible). Since the sequencer normally sends a "Bus stripped" auto-close permissive signal to the EDG output breaker, the EDG output breaker will not auto-close ("B" correct, "C" and "D" wrong).

Current Conditions:
The reactor has tripped due to a Loss ofAll AC Power.
The crew is performing the actions of ECA-O.O, Loss ofAll AC Power.
Initial actions to restore AC power have been unsuccessful.
What actions are required to be taken by the crew with 4KV Bus 34C breakers that supply power to pumps?
a) The control switches are verified to be in Auto-After-Stop (except for the Charging Pump), to allow the sequencer to respond to the LOP when power is restored. The Charging Pump is placed in Pull-To-Lock to prevent thermal-shocking the RCP seals when power is restored.
b) The control switches are verified to be in Auto-After-Stop (except for a Service Water Pump), to ensure RCS makeup is promptly restored when power is restored. The Service Water Pump is placed in Pull To-Lock to prevent overloading the EDG when power is restored.
c) The control switches are placed in Pull-to-Lock (except for the Charging Pump), to prevent a potential overload ofthe power source when power is restored. The Charging Pump is left in Auto-After-Stop to provide core cooling when power is restored.
d) The control switches are placed in Pull-to-Lock (except for a Service Water Pump) to prevent a potential overload ofthe power source when power is restored. The Service Water Pump is left in Auto-After Stop to provide EDG cooling when power is restored.
Proposed Answer:
D Explanation (Optional): Equipment is placed in Pull-To-Lock ("A" and "B" wrong) to permit the operator to evaluate the status ofthe restored bus and sequence loads onto the bus consistent with plant conditions. "D" is correct, and "C" wrong, since one service water pump per train is left in AUTO to provide EDG cooling.
"A" and "B" are plausible, since normally, the preferred switch position is Auto-After-Stop, to ensure prompt loading on an LOP, and preventing thermal shock to the seals is a reason for placing the CHS pump in Pull To-Lock. "C" is plausible, since restoring makeup to the core is a major concern in ECA-O.O.

- 2. The RO adjusts the setpoint too low, bringing in its HI ALARM.
Which area radiation monitor will show an increasing trend due to changing area radiation levels caused by the 3HVR-REI2 ALARM setpoint adjustment?

c) 3RMS-RE13 (Aux 24', Heat exchanger area).
d) 3RMS-REIO (Aux 04', Resin discharge pipe chase area).
Proposed Answer:

Explanation (Optional): "B" is correct, since the automatic action resulting from the alarm on 3 HVR-RE12 causes 3CHS*AOV7l to divert letdown flow to the VCT (away from the degassifier). Radioactive gasses are no longer stripped out ofthe letdown stream, allowing radioactive gasses to accumulate in the VCT gas space, increasing area radiation.

Explanation (Optional): On an LOP, the EDGs will re-energize the emergency busses. The "A" instrument air (lAS) compressor will not have power available, since it is powered from non-emergency bus 32P ("A" and "B" wrong). The "B" lAS compressor has power ("B" plausible), but its breaker tripped on the LOP signaL ES-O.l directs the crew to close the "B" lAS compressor breaker at MB 1 to manually restore lAS header pressure. Resetting LOP is not necessary, since the MB2 LOP reset allows manually stopping loads.
The manual start block ("C" plausible) clears automatically 40 seconds after the EDG energizes the bus, and this time has passed well before reaching the step in ES-O.l ("0" correct, "C" wrong).

Explanation (Optional): The test checks continuity ofthe slave relay, but does not actually operate the associated valve ("C" and "D" wrong). "e" and "D" are plausible, since Tech Spec Acceptance Criteria for a slave relay test requires the energization of each slave relay and verification ofoperability ofeach relay.
Also, "Go" testing of slave relays actually operates components. "B" is correct, and "A" wrong, since the slave relay is blocked from responding to actual signals during continuity testing. "A" is plausible, since during some testing, such as Sequencer Test 1 testing, the equipment gets automatically removed from the Test Mode to respond upon receipt ofan actual signaL Technical Reference(s):

- 1.
The crew commences a downpower using OP 3204, At Power Operations.
- 2.
The pressurizer level controller 3CHS-LK459 level controller setpoint sticks at its original value.
- 3.
The PZR Level Controller is left in AUTOMATIC.
How will Charging Flow Control Valve 3CHS*FCYI21 respond throughout the course ofthe downpower?
a) 3CHS*FCYI2l will throttle closed and letdown will isolate on low pressurizer level.
b) 3CHS*FCYI21 will remain at the same position and maintain PZR level at 64%.
c) 3CHS*FCYI2l will throttle open and maintain PZR level at 64%.
d) 3CHS*FCY121 will open fully and the reactor will trip on high pressurizer level.
Proposed Answer:
~C__
Explanation (Optional): As Thot decreases on the downpower, the RCS water becomes more dense and PZR level will tend to decrease ("B" wrong). "B" is plausible, since Pzr level setpoint is being maintained constant. As power is reduced, the charging flow control valve will throttle open ("A" wrong) to maintain 64% level ("C" correct and "D" wrong). "A" and "D" are plausible, since the pressurizer level controller has malfunctioned with a transient in progress.

With the plant at 100% power, the following sequence of events occurs:
- 1. NIS Channel N41 fails high.
- 2. The operators take prompt action to place rod control in MANUAL
- 3. The crew enters AOP 3571, Instrument Failure Response.
- 4. The crew is preparing to operate the switches on the NIS drawers per AOP 3571.
Which ofthe switch manipulations directed by AOP 3571 is/are physically required in order to restore proper manual and automatic operation ofrod control?
a) The "Comparator Channel Defeat" switch must be taken to Channel "N41" only.
b) The "Power Mismatch Bypass Switch" must be taken to Channel "N41" only.
c) Both the "Comparator Channel Defeat" switch and the "Rod Stop Bypass" switch must be taken to Channel "N41".
d) Both the "Power Mismatch Bypass" switch and the "Rod Stop Bypass" switch must be taken to Channel "N41".
Proposed Answer:
---:::.D__
Explanation (Optional): The "Power Mismatch Bypass" switch removes the faulty channel from the auctioneering input to rod control. The "Comparator Channel Defeat" switch compares all 4 NIS channels, and provides an annunciator if the highest reading channel differs from the lowest channel by >2% ("A" and "C" wrong). Since C-2 is a 114 coincidence, and deenergizes to actuat(:, the "Rod Stop Bypass" switch must also be operated to allow manual rod withdrawal ("D" correct, "B" wrong). "A" and "C" are plausible, since this switch is also operated on a failed NIS channel. "A" and "B" are plausible since many coincidences are 2/4, in which case the "Rod Stop Bypass" switch would not have to be operated.

All SO Narrow Range Levels are 50%.
The following sequence ofevents occurs:
- 1.
"B" SO Narrow Range Level Channel 3FWS*LT527 fails to 0%.
- 2.
The BOP operator takes the control switch for the "8" MDAFW pump to STOP.
How will the "B" MDAFW Pump respond?
a)
The pump stops, and remains off when the BOP operator lets go ofthe switch.
b) The pump stops, and restarts as soon as the BOP operator lets go ofthe switch.
c)
The pump remains running with the Amber breaker disagreement light LIT.
d) The pump remains running, with the Amber breaker disagreement light OFF.
Proposed Answer:
--=..;:A:....-_
Explanation (Optional): The failed "8" SO NR level channel is below the low-low level MDAFW Pp auto start setpoint (1/4 SOs). But, since the coincidence for AFW Pump Auto Start is 2 /4 channels, and only one instrument has failed low, the pump will stop ("A" correct, "8", "C", and "D" wrong). "8", "C", and "D" are plausible, since on an actual low-low level on 1/4 SOs, the pump cannot be stopped by the operator at the Main 80ard until Lo-Lo level is reset.

An RCS leak into CTMT has significantly changed the following parameters in the CTMT atmosphere:
CTMT relative humidity has increased from 38% to 75%.
CTMT iodine levels have increased.
CTMT particulate levels have increased.
The crew enters FR-Z.3, Response to High Containment Radiation Level.
Per FR-Z.3 guidance, the ADTS is considering the use ofthe Containment Air Filtration (CAF) System to lower radiation levels in CTMT.
What is the greatest impact the elevated CTMT humidity level has on the effectiveness ofthe CAF System?
a)
The HEPA filters will be less effective at reducing atmospheric particulate levels.
b) The HEP A filters will be less effective at reducing atmospheric iodine levels.
c)
The charcoal filters will be less effective at reducing atmospheric particulate levels.
d)
The charcoal filters will be less effective at reducing atmospheric iodine levels.
Proposed Answer:
D Explanation (Optional): The CAF system is most effective at removing iodine in the charcoal filters ("C" wrong) and particulates in the HEPA filters ("B" wrong). "D" is correct, and "A" wrong, since increasing humidity significantly reduces the effectiveness ofthe charcoal filters, but not REP A filters (until 95%
humidity conditions are reached). "A", "B", and "C" are plausible, since the CAF System has both REPA and charcoal filters, and removes both particulates and iodine.

and on the purge supply valves (3HVU*CTV32A and 33A) and exhaust valves (3HVU*CTV328 and 338)?
a)

c)
The CTMT Purge Exhaust Fan continues to run. All four supply and exhaust valves close.
d)

Proposed Answer:
A Explanation (Optional): High Radiation isolates the CTMT Purge Supply and Exhaust paths ifEITHER fuel drop monitor goes into alarm. One monitor isolates the supply and return inside containment valves, and the other monitor isolates the outside containment valves ("C" and "0" wrong). The fans do not receive an auto trip signal ("A" correct, "8" wrong). "C" and "0" are plausible, since each ofthese isolates CTMT. "B" is plausible, since the fan is running without a suction path.

A SG Tube Rupture occurs on the "C" Steam Generator, resulting in the following sequence ofevents:
- 1.
The crew enters E-3, Steam Generator Tube Rupture.
- 2.
The crew completes the steps that isolate the ruptured SG.
- 3.
The crew was NOT able to close the "c" and "0" MSIVs.
What adverse effect would there be on the RCS ifthe crew continued on in E-3 with the MSIVs open?
a)
After the RCS cooldown is completed, an excessive dilution of the RCS would occur.
b) While the RCS is being depressurized, a loss ofRCS subcooling would occur.
c)
After the RCS depressurization is completed, the RCS would repressurize.
d) While the RCS is being cooled down, RCS conditions will reach RCP trip criteria.
Proposed Answer:
B Explanation (Optional): "B" is correct since the ruptured SG needs to be isolated from the intact SGs before decreasing the intact steam generator pressures, since this minimizes radiological releases and ensures RCS sub cooling when primary to secondary leakage is terminated in subsequent steps. "A" is wrong, since isolating the ruptured SG allows its pressure to remain higher than the pressures ofthe SGs being steamed to cool down the RCS. The goal is to depressurize the RCS to the point where backflow will occur. "A" is plausible, since this is a basis for choosing ES-3.2 or 3.3 over ES-3.l if there is a concern about backflow.
"C" is wrong, since SI has not yet been terminated, so the RCS will re-pressurize. "c" is plausible, since this is the basis for terminating SI. "0" is wrong because during the cooldown, RCP trip criteria do not apply, but plausible, since RCS pressure will drop below RCP trip criterion pressure during the depressurization.

079.A2.01 Importance Rating 2.9 3.2 Proposed Question:
With the plant initially at 100% power, the following sequence ofevents occurs:
- 2. The crew enters AOP 3562, Loss o/Instrument Air.
- 3. A PEO reports an air leak on an lAS branch line in the turbine building.
- 4. lAS header pressure stabilizes at 85 psig.
- 5. The US directs the PEO to isolate the leak by closing the nearest isolation valve.
- 6. The PEO successfully isolates the leak.
Without further operator action, how will Service Air header pressure respond now that the leak is isolated?
AND, by what method can the PEO locally realign SAS to supply the Service Air header, if needed?
a) SAS header pressure WILL NOT recover. The PEO can manually realign to supply SAS via switches at the local JAS annunciator panel.
b) SAS header pressure WILL NOT recover. The PEO can manually realign to supply SAS by isolating air to 3IAS-AOV14 (SAS to lAS Cross-Connect Valve) and 3SAS-AOV33 (SAS Header Supply Valve).
c) SAS header pressure WILL recover. Ifthe valves fail to automatically reposition, the PEO can manually realign to supply SAS via switches at the local lAS annunciator panel.
d) SAS header pressure WILL recover. If the valves fail to automatically reposition, the PEO can manually realign to supply SAS by isolating air to 3JAS-AOVI4 (SAS to lAS Cross-Connect Valve) and 3SAS AOV33 (SAS Header Supply Valve).
Proposed Answer:
--,-C__
Explanation (Optional): When lAS header pressure decreases to 85 psig, SAS realigns to supply lAS.
Additionally, when lAS header pressure increases to 103 psig, the AOV's automatically realign to their normal positions, and SAS pressure will be maintained (" A" and "B" wrong). "A" and "B" are plausible, since maintaining lAS pressure is a higher priority than SAS pressure. "C" is correct and "D" wrong, since the capability exists to locally align the valves via switches at the lAS annunciator panel. "D" is plausible, since the cross connect valves are AOVs, with normal positions being to supply the SAS header.

With the plant at 100% power, the following sequence of events occurs:
- 1. A deep seated fire starts in the Instrument Rack Room (lRR).
- 2. The Halon System automatically actuates.
Ten minutes after the fire started, the fire brigade desires to enter the IRR to confirm the fire is out, and inspect for damage.
At this time, how can the fire brigade enter the IRR and comply with the precautions ofOP 3341B, Fire Protection Halon System?
a) Ventilate the IRR using the Control Building Purge System. After ventilating, the brigade has unrestricted access to the area.
b) Two brigade members wearing self contained breathing apparatuses can enter the area.
c) Two brigade members wearing canister masks can enter the area.
d)
Station medical personnel in the control room. Then a brigade member in radio contact with the fire brigade leader can enter the area.
Proposed Answer:
B Explanation (Optional): "A" is wrong since the space is not to be ventilated for 30 to 60 minutes for a deep seated fire. Also, the area is not to be ventilated until after the fire is confirmed to be extinguished. "A" is plausible, since if the fire was out and 30 minutes had passed, this would be acceptable. "B" is correct, since prior to ventilating, at least two people are required to enter wearing self contained breathing apparatuses.
"C" wrong, since Halon and decomposition products decompose and form sharp, acrid, gaseous by-products that are not removed by a particulate filter. "C" is plausible, since a canister mask would be effective against particulate agents such as dry-chemical powder, and two people are entering. "D" is wrong, since entry teams require at least two people. "D" is plausible, since the person is in communication with the brigade leader, and medical personnel are required if a person is exposed to Halon.

b) AMSAC will trip the main turbine and start the AFW pumps.
c)
AMSAC will NOT actuate because SG levels are above the AMSAC actuation setpoint.
d)
AMSAC will NOT actuate because it will disarm before the actuation timer expires.
Proposed Answer:
B Explanation (Optional): AMSAC will stay armed for 260 seconds after PT505 failed low and AMSAC actuation is delayed for only 25 seconds after levels go below 16.6% in 3 of 4 SGs ("C" wrong). "B" is correct, and "A" wrong, since AMSAC starts AFW and trips the turbine. "A" is plausible, since AMSAC is designed to mitigate a loss offeed ATWS event. "C" is plausible, since one SG level is above the RPS Lo-Lo level reactor trip setpoint, and another level is not significantly below the RPS SG Lo-Lo level setpoint. "D" is wrong because the timer for actuation is 25 seconds (SG level) which when added to the 210 seconds that have transpired, is still shorter than the 260 second disarming time. "D" is plausible, since Turbine Impulse Pressure failed below the AMSAC disarming pressure, and there are time delays associated with both dis arming and actuation.

The crew is preparing to place the tube side ofan isolated HP Feedwater Heater in service per OP 3321, Main Feedwater, and initial conditions are as follows:
The BOP operator has been designated as the activity coordinator, and has the master copy ofthe "Continuous Use" procedure in-hand in the control room.
The BOP operator will be directing a PEO to perform several procedure steps in the Turbine Building.
The BOP operator directs the PEO to locally perform OP 3321, steps 4.. 18.2.d through 4.18.2.i.
In accordance with AD-AA -102, Procedure Use and Adherence, is the PEO required to have a copy ofthe procedure in-hand locally; and how will the BOP/PEO document the performance ofthe PEO's actions in the master copy ofthe procedure?
a) The PEO IS NOT required to have a copy ofthe procedure in hand. The BOP can place-keep in the master procedure copy based on the PEO's report that a step has been performed.
b) The PEO IS NOT required to have a copy ofthe procedure in hand. The PEO is required to place-keep on the master copy ofthe procedure in the Control Room after the group of steps is completed.
c) The PEO IS required to have a copy of the procedure in hand. The BOP can place-keep in the master procedure copy based on the PEO's report that a step has been performed.
d) The PEO IS required to have the master procedure copy in hand. The PEO is required to place-keep on the master copy of the procedure as the actions are performed.

Explanation (Optional): All personnel who are performing actions in a Continuous Use procedure and are not able to view the master copy shall have a copy ofthe procedure in hand ("A" and "B" wrong), "A" is plausible, since the control room routinely directs PEO actions in the plant. "B" is plausible, since place keeping for a group of steps is allowed for Reference Use Procedures.

A Explanation (Optional): With the plant at 12% power, the "FW PUMPS P4 TRIP BYPASS" selector switch should be in BYPASS (UA" correct), since it is not placed in "NORMAL" until power is above 25% power.
This is a two position "NORMALIBYP ASS" selector switch, located on MB5, and is used to enable or bypass the Reactor Trip signal which trips the MFW Pumps. The Steam Dump "MODE SEL" Switch should be in the Steam Pressure Mode, since it is not placed in Tave Mode until power is above 15% (UB" is wrong, but plausible). The Atm Relief Bypass Valve Cutout Switch should be in LOCKOUT, since these BTP 9.5-1 Fire Safety cut out switches are normally in bypassed to prevent spurious operation in the event of a "hot short". These switches are switched to "Operate" prior to operating the valves, but the condenser steam dumps are in operation ("C" wrong, but plausible). The Feed Isolation Valve position indicator should indicate GREEN, since these valves are bypassed by the Feed Reg Bypass Valves, and are utilized to isolate the Main Feedwater Regulating Valves while feeding with the bypass valves. They are not opened until the crew shifts to the Main Feed Reg Valves at 25% power ("D" wrong, but plausible).

The new alignment IS projected to be a long-term alignment.
d) The new alignment IS a complex alignment.
Proposed Answer:
B Explanation (Optional): An Alternate Plant Configuration is an alignment that is not considered to be the normal configuration ofa system, but is consistent with system design ("A" wrong). It is required when an equipment deficiency necessitates a change to the normal configuration and the change is not specifically addressed by plant procedures ("B" correct). They are intended as temporary, and should be returned to normal as soon as practicable ("C" wrong). They are also intended to be relatively simple configurations. If the configuration is complex, it should be addressed using routine operations such as an approved procedure CD" wrong). "A", "C", and "D" are plausible, since they are all involved in allowing an Alternate Plant Configuration.

A Explanation (Optional): Manual Frisking - Verify that the hand-held frisker is on the "xl" scale, and the background is less than 200 cpm. Pick up the probe and pass it slowly over your body, holding the probe one-half inch away from the surface being checked ("C" and "D" wrong). The probe must be moved very slowly; one to two inches per second. While frisking, watch the needle on the meter face and listen for the clicks. If you observe an increase of 1 00 counts per minute above background, you are considered contaminated and must contact HP ("A" correct, "B" wrong). "e" and "D" are plausible, since 1 to 2 inches per second is the speed that you are required to move the probe. "B" is plausible, since 200 counts per second is the maximum background level above which you are not allowed to frisk.

c)
A control rod does not move offthe core bottom along with its bank.
d)
Sustained startup rate reaches 1.0 decades per minute in the Intermediate Range.
Proposed Answer:
0 Explanation (Optional): Since this KA Statement was selected for the Tier 3 Generic KA section ofthe exam, and ES-40 I, Section 0.2.a provides direction to "Ensure that the questions selected for Tire 3 maintain their focus on plant-wide generic knowledge and abilities and do not become an extension ofTier 2, 'Plant Systems"', this question focuses on administrative requirements to trip the reactor and enter the EOP network, rather than on an entry condition for a specific EOP within the EOP network. "0" is correct, and "A", "B", and "C" wrong, since the two termination criteria that require a reactor trip are: Sustained SUR of 1.0 dpm, and an uncontrolled cooldown that results in Tc being less than 530°F. "A" is plausible, since expected critical time not within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> oftime estimated in the ECC requires the crew to recalculate the ECC. "B" is plausible, since ifcalculations indicate reactor may go critical below the RIL, the crew needs to perform AOP 3566, Immediate Boration, and fully insert all Control Banks. "C" is plausible, since, when the Rod Banks are moved to 10 steps offthe bottom, the crew checks Rod Position Indication, and if any control rods do not move offcore bottom, the crew is directed to Attachment 7 to recover the control rod.

With the plant initially at 100% power, a Pressurizer Safety Valve opens, and the following sequence of events occurs:
- 1.
RCS pressure starts rapidly decreasing.
- 2.
The reactor fails to automatically trip.
- 3.
Safety Injection automatically actuates.
- 4.
The reaetor fails to manually trip.
- 5.
The Load Center 32B breakers fail to open at MB8.
- 6.
RCS pressure is at 1450 psia and decreasing.
What are the next two actions required to be taken by the crew?
a)
Initiate inunediate boration of the RCS, and verify all Turbine Stop Valves are closed.
b) Drive Control Rods in, and verify all Turbine Stop Valves are closed.
c)
Trip the Reactor Coolant Pumps, and initiate immediate boration of the RCS.
d) Trip the Reactor Coolant Pumps, and drive Control Rods in.
Proposed Answer:

Explanation (Optional): "B" is correct, and "A" wrong, since FR-S.l, step 1 RNO directs the rods to be driven in, followed by step 2, which is to check the turbine tripped. "A" is plausible, since the crew will initiate immediate boration of the RCS in step 4 ofFR-S.l. "C" and "D" are wrong, since with the reactor still at power, the RCPs need to be kept running to prevent challenging reactor DNB limits. "C" and "D" are plausible, since E-O RCP trip criteria are met, but they do not apply in FR-S.l.

With the plant initially at 80% power, the following sequence ofevents occurs:
- 1.
It is discovered that one Bank "D" Group 1 rod is not moving with the rest of the bank.
- 2.
The crew enters AOP 3552, Malfonction ofthe Rod Drive System.
- 3.
The crew initiates actions per AOP 3552, Attachment D "Determination ofRod Trippability."
- 4.
When rod movement is attempted, the following reports are made:
The RO reports DRPI indication for the rod does NOT move with Bank Demand Position.
I&C reports affected rod coil currents do NOT conform to their normal pattern.
In accordance with AOP 3552, Attachment D, is the affected rod trippable? Why or why not?
a)
The affected rod IS considered trippable, because there is a DRPI failure.
b) The affected rod IS NOT considered trippable, because the affected rod does NOT move.
c) The affected rod IS considered trippable, because there is a control system failure.
d) The affected rod IS NOT considered trippable, because there is a control system failure.
Proposed Answer:
C Explanation (Optional): "C" is correct, since abnormal coil currents indicate a control system failure, which means the rod is not mechanically bound. "A" is wrong, since Attachment D is entered after a DRPI malfunction has been ruled out. "A" is plausible, since AOP 3552 addresses DRPI failures, and DRPI is not moving with the Demand Signal. "B" and "D" are wrong, since the affected rod is trippable with a control system failure, since if power is interrupted to the rod, it will drop. "B" and "D" are plausible, since abnormal conditions exist with the rod, and it is not moving.

APE.015117.AA2.07 with stopped RCP Importance Rating 2.9 Proposed Question:
With the plant at 30% power, the following sequence of events occurs:
- 2. The crew stops the "C" RCP.
- 3. The plant remains on line during the initial shrink in the affected SO.
How will RCS flow respond in the "C" RCS loop; and what ACTION, if any, is the US required to direct with RCS Loop "C" temperature instrumentation that inputs to Reactor Protection?
a) "C" RCS loop flow will slow down as natural circulation flow is established, maintaining "C" SO temperature at approximately RCS Tave. The temperature bistables ARE NOT required to be tripped, since the instruments are still operable.
b) "C" RCS loop flow will reverse, lowering "C" SO temperature to approximately RCS Tcold' The temperature bistables ARE NOT required to be tripped, since the instruments are still operable.
c) "C" RCS loop flow will slow down as natural circulation flow is established, maintaining "C" SO temperature at approximately RCS T ave' The temperature bistables ARE required to be tripped using AOP 3571, Instrnment Failure Response.
d) "C" RCS loop flow will reverse, lowering "C" SG temperature to approximately RCS Tcold' The temperature bistables ARE required to be tripped using AOP 3571, Instrnment Failure Response.
Proposed Answer:
,.....=.D.,-:-_
Explanation (Optional): When the "C" RCP is stopped, flow in the affected loop will coast down and stop.
Flow will then reverse, since the running RCPs in the other 3 loops will maintain a DP across the core, with the affected loop cold leg pressure at RCP discharge pressure. The idle loop temperature will become very close to Tcold ofthe steaming loops ("A" and "C" wrong). "A" and "C" are plausible, since forced flow has been lost in the affected RCS loop, and if all four RCPs trip, the hot legs will heat up, and natural circulation flow will commence. As for the temperature instrumentation in the affected loop, although it still functions
("A" and "B" plausible), it is only monitoring Tcold temperature, so it is no longer providing a useful input into the DT trips. So the US will direct the affected RCS loop temperature instrument bistables to be tripped using AOP 3571, Instrnment Failure Response ("B" wrong, "D" correct).

- 3. The RO isolates letdown.
What action is required to be taken by the crew?
a) Trip the reactor and enter E-O, Reactor Trip or Safety Injection, since seal inlet temperatures are elevated.
b) Trip the reactor and enter E-O, Reactor Trip or Safety Injection, since seal injection flow has been lost.
c) In accordance with EOP 3506, Loss ofAll Charging, vent the "B" CRS Pump gravity feed boration line, verify a suction path aligned, isolate the Rep seal injection path, and then start the "B" CRS Pump.

Proposed Answer:
D Explanation (Optional): "D" is correct, since with signs of cavitation, the charging pump suction must be vented prior to starting a CHS Pump. "A" and "B" are wrong, but plausible, since a reactor trip is not required unless RCP inlet temperatures are elevated, or Pzr level is lost.

It is decreasing, therefore apply the RNO. Do not stop ECCS pumps. Go to ECA 3.1 ("B" correct).
- 4. PZR level> 16%. Pzr level is 20%.
"A" is plausible since this action would be taken if SI termination criteria were met. "C" is plausible since this action would be taken ifheat sink criteria were not met, and intact SG levels are below 8%. "D" is plausible since this action would be performed ifPZR level was low.

APE.058.GEN..2.4.8 EOPs Importance Rating 4.5 Proposed Question:
With the plant initially at 30% power, the following sequence ofevents occurs:
- 1. Battery Bus 1 deenergizes.
- 2. The crew enters AOP 3563, Loss ofDC Bus.
- 3. The reactor automatically trips.
How is the US required to implement the EOPs! AOPs?
a) The US directs the RO to perform the first two steps ofAOP 3563, Attachment 1 "Loss of DC Bus 1" which establishes RCS temperature control and ensures proper control of AFW. The crew then enters E*
- 0. After completing E-O, step 4, the crew transitions to ES*O.l, Reactor Trip Response and completes the remaining steps of AOP 3563 in parallel with ES-O.I.
b) The US hands AOP 3563 to the extra SRO, who directs the BOP to perform the steps of AOP 3563, "Loss ofDC Bus 1" in parallel with the US, who enters E-O and directs the RO to perform the steps ofE-O. After completing E-O, step 4, the crew transitions to ES*O.I, Reactor Trip Response with the extra SRO and BOP completing all ofAOP 3563, while the US and RO perform ES-O.l.
c) The crew enters E-O. After completing E-O, step 4, the crew transitions to AOP 3563. The US implements the appropriate steps ofAOP 3563, Attachment 1 "Loss ofDC Bus 1" to deal with the impact ofthe loss ofDC bus 1. After the crew completes AOP 3563, the crew transitions to ES-O.l, Reactor Trip Response.
d) The crew enters E-O. After completing E-O, step 4, the crew transitions to ES-O.l, Reactor Trip Response, with the US implementing the appropriate steps ofAOP 3563, Attachment 1 "Loss ofDC Bus 1" in parallel with ES-O.l.
Proposed Answer:
D Explanation (Optional): It is acceptable to perform the actions of an AOP in parallel with an ERG derived EOP provided the actions ofthe ERG-derived procedure receives priority ("C" wrong) and the actions ofthe AOP are not initiated before completing all immediate actions ofthe ERG derived procedure ("A" and liB" wrong). It is not necessary to perform all steps in the parallel procedure. Only those steps necessary to ensure success ofthe ERG derived procedure need to be performed ("D" correct).

A LOCA outside Containment occurs, resulting in the following sequence ofevents:
- 1. The crew enters E-O, Reactor Trip or Safety Injection.
- 3. The crew transitions to ECA-l.2, LOCA outside Containment.
- 4. Immediately after closing Cold Leg Injection Valve SIV"MV8809A, RHR flow drops to 0 gpm.
Has the leak been isolated from the RCS; and to which procedure is the crew required to transition?
a) The leak has NOT been isolated from the RCS. The crew will transition to E-l, Loss 0/Reactor or Secondary Coolant.
b) The leak has NOT been isolated from the RCS. The crew will transition to ECA-l.l, Loss a/Emergency Coolant Recirculation.
c) The leak has been isolated from the RCS. The crew will transition to E-l, Loss 0/Reactor or Secondary Coolant.
d)
The leak has been isolated from the RCS. The crew will transition to ES-l.l, SI Termination.
Proposed Answer:
~B__
Explanation (Optional): Since RHR flow initially existed with RCS above RHR pump shutoff head, the leak was into the RHR System. Since RHR flow dropped to zero with the discharge valve closed, the leak is on the RCS side ofthe isolation valve, so the leak is still active ("C" and "D" wrong). IfECA-1.2 is not successful at isolating a LOCA outside CTMT, the crew will transition to ECA-l.l since no water is entering the CTMT sump to support CTMT recirc ("B" correct, "A" wrong). "A" is plausible, since the crew would transition to E-l ifthe leak was isolated, and a LOCA is still in progress. "C" and liD" are plausible, since RHR flow dropped to zero when the valve was closed.

b)

c)

d)

Proposed Answer:
D
~~-
Explanation (Optional): This event has an element from Diablo Canyon OE: (NRC-IN 2002-10) Feb 9, 2002, where SG level stabilized at 7.5% NR, above the 7.2% trip & AFW actuation setpoint, even though actual level was still decreasing, due to DP across the SG moisture separator. With all WR levels stable above 29%
WR, the 2nd B&F criterion needs to be applied, which is CETCs increasing with RCS pressure at 2350 psia due to a loss ofheat sink. "D" is correct, and "A", "B", and "c" wrong, since RCS temperature is increasing with secondary relief valves open and subcooling decreasing, showing heat sink is not adequate. "A", "B",
and "C" are plausible since these are actions in FR-H.l to restore heat sink if immediate bleed and feed is not yet required, and SG levels are all above the 29% B&F actuation setpoint. Also, there are severa] ways to be at 2350 psia with CETCs increasing that are not due to loss ofheat sink, such as ifSI actuates due to a SG fault, with the RCS heating up after the SG blows dry. "A", "B", and "c" are plausible, since these are heat sink restoration strategies in FR-H.l, wide range SG levels are above bleed and feed criterion, and there are several conditions where CETCs could be increasing with RCS pressure at 2350 psia (such as SIS with a blown down faulted SG) other than due to a loss of heat sink.

Proposed Answer:
-:;..;A:.-...-_
Explanation (Optional): LCO 3.4.8 has three ACTIONS for 1-131 limits, based on activity level and the amount oftime the limit is exceeded. It also has two ACTIONS for Xe-I33 limits. With 1-131 between I and 60 uCi per gram for less than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, power operation may continue up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> while efforts are made to restore RCS Activity to within limits. "C" and "D" are wrong, since the ACTION for Xe-I33 above 81.2 uCi per gram is also 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. IfA" is correct, and "B" wrong, since the basis for limiting RCS activity is to minimize the dose consequences ofa Steam Line Break or a Steam Generator Tube Rupture. "B" is plausible, since radiation would be released on a LOCA as well. "C" and "D" are plausible, since the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> ACTION can be triggered by either I-131 or Xe-133, and by exceeding 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, and AOP 3553 will direct the crew to consider increasing letdown flow to assist with cleanup ofthe RCS.

With the plant at middle oflife conditions, a grid instability event occurs, resulting in the following sequence of events:
- 1. The crew observes that the two lowest-set SG safety valves do not appear to be opening at the required setpoints for each of the Steam Generators.
- 2. The reactor trips.
- 3. The crew enters FR-H.2, Response to Steam Generator Overpressure.

a) 0%
b) 25.5%
c) 42.8%
d) 60.1%.
Proposed Answer:
C Explanation (Optional): The Tech Spec required lift settings per Table 3.7-3 is within 1% following safety valve testing (not the case at Middle ofLife), and within 3% for normal conditions. So the required lift setpoint for the lowest set safety valves (RV22A-D) is 1185 psig x 1.03 1220.55 psig, meaning RV22C and D are not operable. The required lift setpoint for the second-lowest set safety valves (RV23A-D) is 1195 psig x 1.03 1230.85 psig, meaning RV22D is not operable. So, the "D" SG has two inoperable safety valves, requiring the crew to enter ACTION b. This requires power to be reduced (limited) to the limit of Table 3.7-1; and with two inoperable safety valves, the "D" SG still has 3 operable safety valves, requiring power to be limited to 42.8% ("C" correct, "A", "B", and "D" wrong). "A" is plausible, since ACTION d requires the plant to be shutdown if4 or more safety valves are inoperable on one or more SGs, and a total of 8 safety valves lifted more than 1 % outside oftheir lift setpoint. Also, surveillance requirement 4.0.3 prevents increasing modes while relying on an action statement that requires a plant shutdown, but a shutdown is not required for current conditions. "B" and "D" are plausible, since these setpoints are also on table 3.7-1, depending on how many safety valves are operable.

With the plant at 100% power, the following sequence of events occurs:
- 1. NIS power range channel N -41 fails low.
- 2. The crew enters AOP 3571, Instrument Failure Response.
- 3. The US directs the RO to remove channel N-41 from input to the AFD and QPTR monitor alarms for computer program 3R5.
- 4. The RO completes this step 45 minutes after the instrument initially failed.
Now that the RO's actions are completed, what additional action(s), if any, is/are the US required to direct, and why?
a) The US is required to implement AFD monitoring since the AFD Monitor Alarm is considered INOPERABLE. The US is also required to direct preparations to be made for incore flux mapping, since the QPTR Monitor Alarm is considered INOPERABLE.
b) The US is required to implement AFD monitoring since the AFD Monitor Alarm is considered INOPERABLE. The US is NOT required to direct preparations to be made for incore flux mapping, since the QPTR Monitor Alarm is considered OPERABLE.
c) The US is NOT required to implement AFD monitoring since the AFD Monitor Alarm is considered OPERABLE. The US is required to direct preparations to be made for incore flux mapping, since the QPTR Monitor Alarm is considered INOPERABLE.
d) The US is NOT required to implement AFD monitoring since the AFD Monitor Alarm is considered OPERABLE. The US is NOT required to direct preparations to be made for incore flux mapping, since the QPTR Monitor Alarm is considered OPERABLE.
Proposed Answer:
C Explanation (Optional): The AOP actions have removed the affected input from the AFD program, which restores the AFD Monitor Alarm to OPERABLE, so AFD monitoring is not required ("A" and "B" wrong).
The AOP actions have also removed the affected input from the QPTR program, but this does not restore OPERABILITY to the QPTR Monitor Alarm ("C" correct and "D" wrong). "A" and "B" are plausible, since the AFD alarm would be considered INOPERABLE if the RO had taken longer than one hour to complete the AOP 3571 step. "B" and "D" are plausible, since the RO has taken action to remove the failed channel from the QPTR alarm program.

b) In accordance with ECA-O.3, Loss ofAll AC Power - Recovery with the SBa Diesel, open one charging pump cold leg injection valve and increase PZR level above 16%.
c) Actuate Safety Injection, and continue on in ECA-0.3, Loss ofAll AC Power - Recovery with the SBa Diesel.
d) Actuate Safety Injection, and transition to ECA-O.2, Loss ofAll AC Power - Recovery with Sf required.
Proposed Answer:
B Explanation (Optional): The crew has just started a Charging Pump, so the crew has just completed step 6.
With the SBO diesel as the only source ofpower, significant loading limitations exist, so the crew will not transition to another EOP, since other EOPs assume at least one emergency bus is available ("Dn wrong).
The crew will not actuate SIS (nc" wrong), since SI is directed to be reset to allow manual loading of equipment (and avoid overloading the SBO diesel) per the caution prior to step 1 ofECA-O.3. "B" is correct, and "A" wrong, since the cold leg injection valve will supply the maximum amount ofwater from one charging pump with low pzr level. "A" is plausible, since this would raise PZR level, the Charging pump is currently supplying water through FCV 121, and this action is directed in other procedures, such as AOP 3555 RCS leak. "C" and "D" are plausible, since actuating SI would raise PZR level, PZR level is below the SI reinitiation setpoint on the foldout page of several EOPs. Also, ECA-O.2 would be the correct choice if either offsite power or an EDG were supplying power.

004.A2.28 Proposed Question:
Importance Rating 4.3 The following initial sequence of events occurs:
- 1. A Steam Generator Tube Rupture occurs on the "c" SG.
- 2. The crew enters E-3, Steam Generator Tube Rupture.
- 3. The crew prepares to depressurize the RCS to minimize break flow and refill the pressurizer.
- 4. The crew is NOT able to commence depressurizing the plant by any ofthe methods directed in E-3.
- 5. The crew transitions to the appropriate Emergency Contingency Action procedure, with current conditions as follows:
RCS subcooling is 80°F.
- "c" SG NR level is 70%.
"C" SG pressure is 1085 psig.
The crew commences depressurizing the RCS by stopping one Charging Pump, both SIH pumps, and realigning charging through the normal charging flowpath.
To what pressure will the RCS initially depressurize ifno operator action is taken; and when is the crew required to take action to terminate the depressurization?
a) The RCS will depressurize to and stabilize at ruptured SG pressure. The crew will terminate the depressurization ifsubcooling decreases to 32°F, or ifPlenum level drops to less than 19%.
b) The RCS will depressurize to and stabilize at ruptured SG pressure. The crew will terminate the depressurization when the RCS reaches saturation conditions, or ifPzr level exceeds 73%.
c) The RCS will depressurize to and stabilize at CETC saturation pressure. The crew will terminate the depressurization ifsubcooling decreases to 32°F, or ifPlenum level drops to less than 19%.
d) The RCS will depressurize to and stabilize at CETC saturation pressure. The crew will terminate the depressurization when the RCS reaches saturation conditions, or jfPzr level exceeds 73%.
Proposed Answer:
-:..:A~,..._
Explanation (Optional): With no pressure control, the crew is required to transition to ECA-3.3. This will stop ECCS and realign charging to cause depressurization and terminate break flow. With no SI flow, break flow will rapidly empty the Pzr, and partially drain the hot leg. When steam hits the subcooled hot leg water, it will condense, continuing the depressurization, until the RCS reaches SG pressure ("C" and liD" wrong).
"C" and liD" are plausible, since during a LOCA, the RCS would continue to depressurize, and for loss of heat sink events, pressure would hold up at the point where the hot legs are saturated. "AI! is correct, and "B" wrong, since termination criteria are subcooling < 32°F, or plenum level < 19%. "B" is plausible since this is termination criteria from ECA-3.2, which the crew would enter based on high SG level, and it is elevated.

005.A2.03 Importance Rating 3.1 Proposed Question:
INITIAL CONDITIONS:
Plant is in MODE 5, solid plant operations, on the"A" Train ofRHR "B" Electrical Distribution Train outage is in progress, and cannot be immediately restored RCS temperature is 150°F RCS pressure is 150 psia All RCS loops are full, swept, and vented.
All Steam Generators are in Wet-Layup The "A" Charging Pump is running No RCPs are running The"A" RHR Pump shaft shears, and its flow drops to zero.
What action will the crew take to remove decay heat?
a) Open both PORVs, and fill the RCS using one Charging Pump from the RWST.
b) Open both PORVs, and fill the RCS using one SI Pump from the RWST.
c) Throttle open the charging line flow control valve to raise RCS pressure to > 170 psia, and open the Steam Generator Atmospheric Relief Valves.
d)
Start one Reactor Coolant Pump, check proper differential pressure across its # 1 seal, and open the Steam Generator Atmospheric Relief Valves.
Proposed Answer:
---:;;C__
Explanation (Optional): "c" is correct, since the RCS is already full and steam generators are available. The procedure has conditions established for natural circulation, RCS pressure is increased to ensure subcooled natural circulation cooling, and the steam generators are used to dump steam. "A" and "B" are wrong, but plausible, since bleed and feed is only used ifnatural circulation cooling is unsuccessful. The charging pump is the preferred feed source, and the SI Pump is the backup source offeed. "D" is wrong, but plausible, since forced cooling is only used if a RCP is already running.

o13.GEN.2.2.39 Proposed Question:
Importance Rating 4.5 A refueling outage has just been completed, and Initial Conditions are as follows:
Two pzr Pressure Transmitters (3RCS*PT455 and PT456) were replaced during the outage.
The plant is in MODE 3.
The crew is performing a plant heatup per OP 3201, Plant Heatup.
The following sequence ofevents occurs:
I.
Pzr pressure increases above 2000 psi a as indicated on Pzr Pressure Transmitters 3RCS*PT457 and 458.
- 2.
The RO reports 3RCS*PT455 and PT456 still indicate 1950 psia.
- 3.
The RO reports the "Pressurizer Pressure Lo Interlock P-ll" permissive window on MB4 is lit.
- 4.
3RCS*PT455 and PT456 are both declared INOPERABLE.
Based on the failed instruments and current permissive status, what ACTION is the crew required to take?
a)
The plant startup may proceed provided the associated Bistables are tripped within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

c)
Suspend the plant startup, and enter LCO 3.0.3.
d)
Suspend the plant startup. Entry into LCO 3.0.3 is NOT required.
Proposed Answer:
- --",C=-:-
Explanation (Optional): With an ESF AS Instrumentation Channel or Interlock Channel found to be inoperable, declare the channel inoperable and apply the applicable ACTION statement requirements of Table 3.3-3 until the channel is restored to OPERABLE status.
Per Functional Unit 9: Engineering Safety Features Actuation System Interlocks for Pressurizer Pressure, P 11, ACTION 21 applies, with the total channels'" 3, and minimum channels 2. With less than the Minimum Number of Channels OPERABLE, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> determine by observation ofthe associated permissive annunciator window(s) that the interlock is in its required state for the existing plant condition ("A" and "B" wrong), and since P-II is now in the wrong state (2 of 3 channels less than 2000 psia), apply Specification 3.0.3 ("C" correct, "D" wrong). The crew also needs to enter LCO 3.0.3 due to Low Pzr Pressure SI less than minimum channels per Functional Unit l.d, ACTION 20. "A" and "B" are plausible, since numerous RPS and ESF bistables require tripping within I hour, and others within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. And this action would be correct, if one channel was low (less than total channels, but not less than minimum). "D" is plausibJe, since this would be correct for P-l1 ifthe permissive were in the required state.

059.GEN.2.4.4 Importance Rating 4.7 Proposed Question:
With the plant at 100% power, a transient occurs, and initial conditions are as follows:
Reactor power is 100% and stable.
RCS T ave is 588°F and slowly increasing.
RCS pressure is 2260 psia and slowly increasing.
"A" SG NR Level is 35% and decreasing.
Containment pressure is 16 psia and increasing.
CTMT HI-t pressure is reached, and SIS actuates.
For this event, which operator credited action is the crew required to complete to mitigate this event; and to which procedure will the crew transition after completing E-O?
a) The crew is required to check PORV Block valves OPEN within 70 minutes from initiation of safety injection. They will transition from E-O to E-l, Loss ofReactor or Secondary Coolant.
b) The crew is required to check PORV Block valves OPEN within 70 minutes from initiation of safety injection. They will transition from E-O to E-2, Faulted Steam Generator Isolation.
c) The crew is required to isolate auxiliary feedwater to the affected steam generator within 30 minutes from event initiation. They will transition from E-O to E-l, Loss ofReactor or Secondary Coolant.
d) The crew is required to isolate auxiliary feedwater to the affected steam generator within 30 minutes from event initiation. They will transition from E-O to E-2, Faulted Steam Generator Isolation.
Proposed Answer:
_D__
Explanation (Optional): A feedline break inside CTMT is in progress (CTMT pressure is increasing, since energy is being released to CTMT; and SG level is decreasing since feed is not reaching the SG, and SG inventory is being lost out ofthe break). An operator-credited action for a feedline break is to isolate auxiliary feedwater to the affected steam generator within 30 minutes from time ofbreak ("A" and "B" wrong). After the feedline uncovers, the SG will depressurize, and the crew will be required to enter E-2 (HC" wrong and "D" correct). "A" and "B" are plausible, since E-t would be entered for a LOCA, and energy is being released to CTMT, and normal indication for a faulted SG on a steamline break is RCS cooldoWll. "e" is plausible, since this is an operator credited action for an inadvertent SI.

Importance Rating 2.9 A plant heatup is in progress per OP 3201, Plant Heatup, and initial conditions are as follows:
RCS temperature is 190°F and stable.
RCS pressure is 350 psia and stable.
The PZR is solid.
The following sequence of events occurs:
- 1. Instrument Air pressure starts rapidly decreasing.
- 2. The crew enters AOP 3562, Loss ofInstrument Air.
- 3. A PEO who is dispatched to investigate reports the following:
The INST AIR A AFT CLR OUT TEMP HI annunciator is lit.
Instrument Air Filter Differential Pressure is 6 psid.
In accordance with AOP 3562, Attachment A, "Loss ofInstrument Air Local Actions," what action will the US direct the PEO to take; and ifIAS pressure continues to decrease, what will be the effect on RCS pressure?
a) The US will direct the PEO to place the emergency instrument air dryer in service. I£lAS pressure continues to decrease, RCS pressure will increase to a maximum ofabout 455 psia.
b) The US will direct the PEO to place the emergency instrument air dryer in service. If lAS pressure continues to decrease, RCS pressure will increase to a maximum ofabout 2350 psia.
c) The US will direet the PEO to swap the in-service instrument air mters. IfIAS pressure continues to decrease, RCS pressure will increase to a maximum of about 455 psia.
d) The US will direct the PEO to swap the in-service instrument air mters. If lAS pressure continues to decrease, RCS pressure will increase to a maximum ofabout 2350 psia.
Proposed Answer:
C Explanation (Optional): Question is considered SRO, since it requires detailed assessment ofplant conditions, including Tech Spec required status of COPPS in lower MODEs. AOP 3562, Attachment A requires the crew to swap filters ifDP is above 4 psid, but does not require swapping air dryers unless specific annunciators are lit, and they are not ("A and "S wrong). "A" and "S" are plausible, since an lAS annunciator is lit. IflAS pressure is lost, RHR letdown valve 3CHS*PCV 131 will fail closed, causing RCS pressure to increase. Since COPPS is required by Technical Specifications, and will remain ARMED until 230oP, and since the PORVs are not air operated valves, COPPS will mitigate the pressure rise at 455 psia
("C" correct, "0" wrong). "0" is plausible, since ifCOPPS were blocked, the PORVs would lift at 2350 psia.

The plant is in MODE 2, with a Reactor Startup in progress.
Train "A" ICC/RVLMS indications are normal.
Train "B" ICC!R VLMS indications are normal, except for the 100% head level sensor, which is not functioning due to a failed heater.
The following sequence ofevents occurs:
- 1. An open circuit occurs in the Train "B" 63% Head RVLMS unheated thermocouple.
- 2. Plant Process Computer indication for the Train "B" 63% Head RVLMS detector turns BLUE and shows an "X" Quality Tag.
- 3. I&C determines that the head 63% thermocouple is not repairable with the plant on line.
Using the attached copy of LCO 3.3.3.6, what ACTION, if any, is required?
a) No ACTION is required. Both Trains ofRVLMS are still OPERABLE.
b) No ACTION prohibiting the reactor startup is required. Either restore the "B" Train ofRVLMS to OPERABLE within 7 days or submit a Special Report to the NRC within 30 days.

d) Halt the startup until an alternate method of measuring reactor vessel inventory has been implemented.
Submit a Special Report to the NRC within 30 days, and restore the "B" Train ofRVLMS to OPERABLE status at the next scheduled refueling.
Proposed Answer:
B Explanation (Optional): Train B is INOPERABLE since, per Table 3.3-10, a probe is considered OPERABLE ifhalfor more ofthe head and half or more ofthe plenum detectors are OPERABLE; and both head detectors are inoperable. "A" is plausible, since train "A" is fully functional, and less than half ofTrain "B" detectors are inoperable, but they are both in the head. "B" is correct, since, per T.S 3.3.3.6 "Accident Monitoring" ACTION e. is applicable for one channel failure. ACTION g. allows transition to an OPERATIONAL MODE while in the ACTIONS of 3.3.3.6. "C" and "D" are wrong, since only one channel has failed, and the other channel is still OPERABLE. "C" is plausible, since this is the action for less than total channels for Accident Monitoring except R VLMS and CTMT Hi Range Monitor. ltD" is plausible, since this is related to the action for RVLMS less than minimum channels.

Initial Conditions:
- 1. The crew is in E-3, Steam Generator Tube Rupture due to a tube rupture on the "B" SG.
- 2. The crew is preparing to commence the cooldown ofthe RCS.
A safety valve lifts on the ruptured "B" SG, and sticks fully open.
How will "B" SG Wide Range level respond, and what procedure will the crew initially enter to mitigate this event?
a) Ruptured SG Wide Range level will decrease. The crew will transition to E-2, Faulted Steam Generator Isolation.
b) Ruptured SG Wide Range level will increase. The crew will transition to E-2, Faulted Steam Generator Isolation.
c) Ruptured SG Wide Range level will decrease. The crew will transition to ECA-3.1, SGTR with Loss of Reactor Coolant - Subcooled Recovery Desired.
d) Ruptured SG Wide Range level will increase. The crew will transition to ECA-3.1, SGTR with Loss of Reactor Coolant - Subcooled Recovery Desired.
Proposed Answer:
-..:;..:A:.-_
Explanation (Optional): Ruptured SG WR level and pressure will decrease due to loss ofmass out the failed open safety valve ("B" and "D" wrong). "B" and "D" are plausible, sillce NR level would experienee swell as the SG depressurizes, and RCS break flow rate will increase as the ruptured SG depressurizes. However, a design basis tube rupture is about 300 gpm, and a safety valve can pass about 5% steam flow, which is over 500 gpm. "A" is correct, and "C" wrong, since the crew is required to transition to E-2 to isolate the faulted SG prior to continuing with mitigation per E-3 series procedures. "C" is plausible, since the crew is at a step that will send them to ECA-3.1 if SG pressure drops to 530 psig, and they will ultimately transition to ECA 3.1 to mitigate the faulted, ruptured SG.

A plant cooldown is in progress in accordance with OP 3208, Plant Cooldown, and initial conditions are as follows:
Both trains ofRHR are in service in the Cooldown Mode.
Pressurizer level is stable at 55%.
RCS cold leg temperatures are 250°F and decreasing.
RCS pressure is 350 psia and stable.
PZR temperature and surge line temperature are both stable at 430°F.
All Pressurizer heaters are energized.
The RO reports that pressurizer surge line temperature has started decreasing, indicating 420°F.
What adverse plant condition exists, and what action is the US required to direct?
a) Spray flow has initiated with AT across the Pressurizer spray nozzle in excess ofTRM limits. The US will direct the extra senior licensed operator to notify Engineering and initiate a CR.
b) Spray flow has initiated with AT across the Pressurizer spray nozzle in excess ofTRM limits. The US will direct the RO to deenergize pressurizer heaters to restore AT to within limits within 30 minutes.
c) A pressurizer insurge is in progress, with AT between the RCS and Pzr applying thermal stress to the PZR Surge Line. The US will direct the RO to adjust Charging Flow Control Valve 3CHS*FCVI21 to decrease charging flow.
d) A pressurizer insurge is in progress, with AT between the RCS and Pzr applying thermal stress to the PZR Surge Line. The US will direct the RO to adjust Letdown Pressure Controller 3RCS-PK131 to decrease letdown flow.
Proposed Answer:
C Explanation (Optional): In this situation, the pressurizer level control system is being used to maintain PZR level constant with spray flow adding water to the PZR at a rate greater than the net charging rate to the RCS as the RCS contracts during the cool down. This establishes a continuous PZR outsurge, preventing a PZR insurge and the associated thermal transient. Ifnet charging flow increases above the 35 gpm spray flow, an insurge occurs, as evidenced by the surge line temperature drop. The US must either increase letdown flow
("0" wrong, but plausible) or decrease charging flow ("C" correct). There is a 182°F temperature difference between the RCS and the PZR, which is within the 200°F spray nozzle administrative limit. "A" lists actions required ifthe 200°F limit is exceeded, and "B"lists the actions related to the TRM 320°F limit. (" A" and liB" wrong, but plausible).

A small, short-term transient occurs at the end ofthe computer-defined 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> shift, and the following reports are made:
Current calorimetric 4-minute average power indication is at 3660 MWth based on a steam flow calculation.
Thc 12-hour shiftly average power comes in at 3650.1 MWth.
In accordance with OP 3204, At Power Operation, what are the minimum actions (in addition to submitting a CR, and maintaining the shiftly average power less than or equal to 3650 MWth) required to be performed by the crew?
a) Monitor 4-Minute Average Power, and ensure it returns to less than or equal to 3650 MWth within 20 minutes, and notify Reactor Engineering. This is NOT a reportable event.
b) Monitor 4-Minute Average Power, and ensure it returns to less than or equal to 3650 MWth within 20 minutes, and notify Reactor Engineering, requesting they determine Reportability.
c) Reduce power to less than or equal to 3650 MWth, and notify Reactor Engineering. This is NOT a reportable event.
d)
Reduce power to less than or equal to 3650 MWth, and notify Reactor Engineering, requesting they determine Reportability.
Proposed Answer:
---=.D__
Explanation (Optional): The crew is directed to maintain the 4 minute average less than or equal to 3650 MWth. "A" and "B" are wrong, since allowance is made for brief, statistical fluctuations ofup to 0.2%
power (3657 MWth), but this has been exceeded. IF the "4 minute average" THERMAL POWER (CVQRP A) exceeds 100.2% (3,668 MWth), the crew is required to reduce power to less than 3650 MWth.
"An and "B" are plausible, since ifpower exceeds 3650 MWth by less than 0.2%, the crew is generally allowed 15 to 20 minutes to analyze the transient prior to having to reduce power. "D" is correct, and "C" wrong, since ifthe 12-hour average exceeds 3650 MWth, Reactor Engineering must be requested to determine Reportability. "A" is plausible, since power has not exceeded 102% by either 4-minute or shiftly calculation, which is the 4-minute average power trigger to determine reportability.

GEN.2.2.39 Importance Rating 4.5 Proposed Question:
The plant has been shutdown for secondary plant repairs, and Initial Conditions are as follows:
A reactor startup is in progress per OP 3202, Reactor Startup (ICCE).
Reactor power is stable at I x 10-8 amps.
The crew is preparing to take critical data.
The STA reports that Tave has dropped to 550°F.
What Technical Specification ACTION, ifany, is required?
a)
Restore Tavg within 15 minutes OR be in HOT STANDBY within the next 15 minutes.
b)
Restore compliance AND be in HOT STANDBY within one hour.
c)
No ACTION is required, sinee LCO Section 3.10 SPECIAL TEST EXCEPTIONS applies.
d) No ACTION is required, since the plant is NOT in MODE L Restore Tavg prior to entering MODE 1.
Proposed Answer:
A Explanation (Optional): This question is considered SRO level, sinee an ICCE (Infrequently Conducted Complex Evolution) is in progress with the plant in MODE 2, and the candidate must discern whether the special test exemption associated with LCO 3.1.1.4 applies. With a Reactor Coolant System operating loop temperature (Tavg) less than 551°F, restore Tavg to within its limit within 15 minutes or be in HOT STANDBY within the next 15 minutes ("A" correct, "B", "C", and "D" wrong). uB" is plausible, this is the action required ifa core safety limit were violated. HC" is plausible, since a special test exception applies to LCO 3.1.1.4, and this would be correct ifthe startup involved low power physics testing. "D" is plausible, since in MODE 2, and the action would not apply ifKeff were less than one.

GEN.2.3.11 Importance Rating 4.3 Proposed Question:
A refueling outage is in progress, and initial conditions are as follows:
Radiography is in progress in the Auxiliary Building, 4 foot level.
The "B" Waste Test Tank (WIT) is being discharged.
The following sequence ofevents occurs:
- 1. Discharge Tunnel Effluent Control Valve 3LWS-HV77 trips closed due to a Hi Radiation Alarm, stopping the WTT discharge.
- 2. The Hi Radiation alarm clears on 3LWS-RE70.
- 3. The "B" WTT is placed on recire.
- 4. Chemistry samples the "B" WTT, and sample results are the same as the original sample.
- 5. 3LWS-RE70 is purged.
In accordance with OP 3335D, Radioactive Liquid Waste System, what is required prior to discharging the "B" WTT?
a) Relatch and open 3LWS-HV77, and continue the discharge.
b) Flush the discharge piping for 15 minutes, relatch and open 3LWS-HV77, and continue the discharge.
c) Issue a new discharge permit, and commence a new discharge.
d) Perform an independent sample, and an independent valve lineup. Relateh and open 3LWS-HV77, and continue the discharge.
Proposed Answer:
A Explanation (Optional): When LWS-RE70 goes into alarm, recirc and sample is required. "A" is correct, and "B", "C", and "D" wrong, since the sample shows tank contents are as expected, and the radiation alarm has cleared. "B" and "c" are plausible, since flushing and issuing a new permit are required ifsample results show greater activity than the original sample. "D" is plausible, since these actions are related to actions if 3LWS-RE70 is inoperable.

GEN.2.4.6 Importance Rating 4.7 Proposed Question:
Current Plant Conditions:
Core Exit Thermocouples read 1250°F.
The crew is progressing through FR-C. I, Response to Inadequate Core Cooling.
The crew has been unsuccessful at restoring High Head Safety Injection.
The crew has been unsuccessful at depressurizing the secondary plant.
Which is the next major action that will be attempted, and how/why will the step be implemented?
a) One RCP is started at a time to maximize the time core cooling is provided, temporarily cooling the core with RCS loop crossover leg water.
b) All RCPs are started at once to provide symmetrical cooling of the core via heat transfer to the Steam Generators.
c) Both pzr PORVs and both Reactor Head Vent Valves are opened to reduce RCS pressure low enough to allow low pressure safety injection from the SIL Accumulators.
d) Both Pzr PORVs are opened to reduce RCS pressure low enough to allow low pressure safety injection from the RHR Pumps.
Proposed Answer:
A Explanation (Optional): In FR-C.l, the third major action is to start all RCPs ("C" and "D" wrong). The background document states that starting an RCP (with adequate heat sink) will force two phase flow through the core, temporarily keeping it cool with crossover leg water. The steps are designed to start one RCP at a time, to extend the time the core is kept cool while the plant staffworks at restoring either high head injection or the ability to depressurize the secondary plant ("A" correct, and "B" wrong). "B" is plausible, since the next major action is to start RCPs, and symmetrical cooling is a basis for starting an RCP while on natural circulation. "c" and "D" are plausible, since the next major action strategy after starting RCPs is depressurizing the RCS by opening primary plant relief valves, and tbe basis is to get low head injection from accumulators and/or RHR pumps.

GEN.2.4.23 Importance Rating 4.4 Proposed Question:
A small break LOCA occurs, resulting in the following sequence ofevents:
I. Core Exit Thermocouples increase to 720°F.
- 2. The crew transitions to the appropriate Functional Response Procedure.
- 3. The crew commences depressurizing all intact SGs to 190 psig.
During the sa depressurization, the INTEGRITY critical safety function status tree turns RED.
Is the US required to direct a transition to FR-P.l, Response to Imminent Pressurized Thermal Shock? Why or why not?
a) Yes, since FR-P.l will be addressing an "extreme" challenge to a fission product barrier, while the current procedure is only addressing a "severe" challenge to a barrier.
b) Yes, since FR-P.l will take actions that more directly protect a higher priority fission product barrier than that being addressed by the current procedure.
c) No, since the current procedure is addressing an "extreme" challenge to a fission product barrier, while FR-P.l would only be addressing a "severe" challenge to a barrier.
d) No, since the current procedure is taking actions that more directly protect a higher priority fission product barrier than that being addressed by FR-P.I.
Proposed Answer:
-=.D__
Explanation (Optional): Status tree monitoring is based on RED being the highest priority "extreme" challenge to a fission product barrier, while an orange path (current core cooling tree color, above 718°F) is considered a lower priority "severe" challenge. Also the trees are prioritized based on which barrier they protect, with the priority being the clad first, then the RCS, and finally CTMT. For this event, it is expected that during the sa depressurization, the integrity tree may tum RED, since accumulators will inject as RCS pressure lowers, and cold accumulator water will flow past the RCS Tcold instruments, and into the vessel.
nAn and "B" are wrong, since for this event, the operators are required to remain in C.2 ("C" plausible), to restore adequate core cooling, since the core cooling status tree directly protects the Clad, which is a higher priority barrier than the RCS (nD" correct, "C" wrong). "A" and "B" are plausible, since normally (when actions ofone FR do not conflict with another FR), the RED path ("extreme challenge) on integrity would be a higher priority than the Orange path ("severe" challenge) for core cooling.
