During power operation it is discovered Bank 'D' Group 1 rods will not move. Investigation reveals a single slave cycler is not putting out the correct current orders to the affected coils.
Which of the following statement explains why the affected rods are, or are not considered trippable?
A. The affected rods are trippable because there is a control system failure.
B. The affected rods are not trippable because there is a control system failure.
C. The affected rods are trippable because the coil currents will not vary greatly from their normal pattern.
D. The affected rods are not trippable because there is a problem with the control rod stepping sequence.
Proposed Answer: A Explanation (Optional):
'A' correct, Note prior to step 1 states that "rods trippability may be confirmed by verification of control system failure, usually electrical in nature or verification of a failure associated with a control rod stepping mechanism" (such as a failed slave cycler).
'B' incorrect, affected rods are trippable with a control system failure.
'C' incorrect, trippability is not linked to coil current variations.
'D' incorrect, affected rods are trippable with a failed slave cycler.

Proposed Question:
Off site power is lost due to an approaching hurricane, and sustained wind speeds of 95 mph are expected on site within 6-8 hours. The crew is preparing to commence a natural circulation cooldown of the RCS.
How is the implementation of ES-0.2, "Natural Circulation Cooldown", affected by these conditions?
A. The crew will maintain RCS pressure at 1950 psia throughout the cooldown.
B. When the crew reaches step 16 of ES-0.2, they should leave the accumulator isolation valves open.
C. The crew should maintain a minimum of 132 0 F subcooling based on core exit TCs during the cooldown.
D. Prior to commencing the cooldown, the crew will transition to ES-0.3 "Natural Circulation Cooldown with Steam Void in Vessel (with RVLMS)".
Proposed Answer: B Explanation (Optional):
'B' is correct per ES-0.2 note prior to step 7
'A' incorrect, depressurizing the RCS is desired to approach accumulator injection pressure to mitigate the impact of a potential loss of all AC.
'C' incorrect, this is the action required if CRDM fans are lost.
'D' incorrect, 6-8 hours is adequate time to cooldown to 400 degrees F and a void in the vessel is not desired.

The following sequence of events occurs:
- 2. The crew is in E-3 "Steam Generator Tube Rupture", and is preparing to depressurize the RCS to minimize break flow and refill the pressurizer.
- 3. When the RO attempts to commence spraying the pressurizer with the normal spray valves, neither spray valve will open.
What method will the crew use to depressurize the RCS, and why?
A. Depressurize the RCS using a Pzr PORV, to minimize thermal stresses on the spray nozzle.
B. Depressurize the RCS using a Pzr PORV, to prevent adverse containment conditions.
C. Depressurize the RCS using the auxiliary spray valve to provide a more controlled depressurization rate than using the Pzr PORVs.
D. Depressurize the RCS using the auxiliary spray valve to minimize the loss of reactor coolant.
Proposed Answer: A Explanation (Optional):
A Pzr PORV should be used instead of aux spray ("C" and "D" wrong) to minimize thermal stresses on the spray nozzle ("A" correct and "B" wrong), and since aux spray may not be sufficient to rapidly decrease RCS pressure. "C" and "D"are plausible since aux spray is preferred in ES-3.1 if letdown is in service. "B" is plausible since this is a reason given supporting the use of aux spray.

INITIAL CONDITIONS:
"* The reactor is at End of Life
"* The reactor has just been returned to criticality after an extended shutdown period.
"* Tave is 557 0 F.
A major steamline break occurs on one main steam line. All equipment operates as designed, except for the most reactive rod, which sticks fully withdrawn on the reactor trip.
According to the FSAR, which of the following describes the function Safety Injection provides for this limiting event?
A. Limit peak power following recriticality by boron injection.
B. Limit PTS concerns by limiting the cooldown.
C. Prevent loss of pressure control by refilling the pressurizer.
D. Prevent a return to criticality.
Proposed Answer: A Explanation (Optional):
The cooldown can be stopped by isolating the steam break, or by stopping feed to the faulted SG, and allowing it to dry out. SI water will not stop the cooldown ("B" incorrect). The analysis does not cover return of control systems or refill of the pressurizer, and pressure control is difficult with SI injecting on a secondary fault. Pressure will be maintained by cycling Pzr PORVs ("C" incorrect). SI provides borated water which adds negative reactivity to compensate for the positive reactivity added due to the cooldown. It is assumed that the reactor returns to criticality prior to SI water reaching the core, and that the power reached will be limited by the addition of borated water adding negative reactivity ("A" correct, "D" wrong). "B" is plausible since cooldown adds thermal stress to the RCS. "C" is plausible since the cooldown causes a shrinkage of the RCS inventory, emptying the pressurizer.

What is the color of the RCS Integrity Status Tree at 1000?
A. Green B. Yellow C. Orange D. Red Proposed Answer: A Explanation (Optional):
Status tree will indicate green until you have > 100F/Hr cooldown in any cold leg, and temperature is <286°F. The status tree turns yellow at <286°F ("A" correct, "B" wrong). The status tree turns orange at 256°F ("C" wrong), and red below a variable setpoint <256 0 F ("D" wrong). "B", "C", and "D"are plausible since a cooldown > 100°F has occurred.

Reactor power is steady at 40% when condenser backpressure starts to increase.
0 The crew has entered AOP 3559, "Loss of Condenser Vacuum".
0 Condenser backpressure is 4.1 inches Hga and increasing.
What action should a PEO currently be performing outside of the control room?
A. Adjusting gland seal pressure to between 2 and 6 psig.
B. Verifying that one process vent fan is running.
C. Closing steam dump isolation valves per AOP 3550 "Turbine Generator Trip".
D. Closing the feeder breaker on 32T to MCC32-3T per ES-0.1 "Reactor Trip Response".
Proposed Answer: B Explanation (Optional):
"B" is correct, since the condenser air ejectors discharge to the process vent system. "A" is wrong, since this action is performed from the main boards. "C" and "D" are wrong since the foldout page of AOP 3559 requires a reactor trip if condenser backpressure is > 7.5" Hg, or > 5 inches and turbine load is < 360 MWe (30% reactor power). "A" is plausible since this is an action in AOP 3559.
"C" is plausible since power is 40%, and AOP 3550 would normally be entered if a turbine trip setpoint was exceeded. "D" is plausible since if a trip setpoint was reached per AOP 3559 foldout page, E-0 should be entered rather than AOP 3550, since the condenser is not available.

PLANT CONDITIONS:
"* A loss of all AC power event is in progress.
"* The crew is depressurizing the steam generators to 260 psig.
"* RCS pressure is 1400 psia and decreasing.
"* The RO reports that PZR level is rapidly increasing.
Which of the following actions should be taken by the crew?
A. Continue the depressurization; this is an expected plant response.
B. Continue the depressurization; accumulators are injecting into the RCS.
C. Halt the depressurization and vent the reactor vessel head to remove the voids.
D. Halt the depressurization and allow RCS pressure to rise to collapse the voids.
Proposed Answer: A Explanation (Optional):
"A" is correct, and "C" and "D" are wrong, since PZR level may be lost and reactor vessel upper head voiding may occur due to depressurization of SGs. Depressurization shall NOT be stopped to prevent these occurrences, and one indication of voiding is rapidly increasing PZR level. "B" is wrong since accumulator pressure is 660 psia. "B" is plausible, since one of the main goals of the depressurization is accumulator injection. "C" and "D"are plausible, since these actions are used in other procedures to collapse voids.

With the plant at 100% power, the following sequence of events occurs:
- 1. A loss of power to VIAC-1 occurs.
- 2. The operators take prompt action to stabilize SG levels
- 3. The crew enters AOP 3564 "Loss of One Protective System Channel".
- 4. Rods are placed in MANUAL.
- 5. The crew has selected the alternate channel on turbine impulse pressure, and has defeated loop 1 Tave.
Assuming power is not restored to the VIAC, what action(s) is (are) physically required at the NIS drawers for NIS channel N-41 in order to restore proper automatic operation of rod control?
A. The "Comparator Channel Defeat" switch must be taken to "bypass" only.
B. The "Power Mismatch Bypass Switch" must be taken to "bypass" only.
C. Both the "Comparator Channel Defeat" switch and the "Rod Stop Bypass" switch must be taken to "bypass".
D. Both the "Power Mismatch Bypass" switch and the "Rod Stop Bypass" switch must be taken to "bypass".
Proposed Answer: D Explanation (Optional):
The "Power Mismatch Bypass" switch removes the faulty channel from 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 1/4 coincidence, and deenergizes to actuate, the "Rod Stop Bypass" switch must also be operated ("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.

D. Establish alternate cooling to the charging pump cooling system.
Proposed Answer: D Explanation (Optional):
AOP 3560 directs using Attachments "A" and "B" as guidance if a transition to E-0 is made.
Attachment "A" has RCP trip criteria and Attachment "B" is the feed and bleed procedure. "A" is wrong since RCPs are tripped from the control room. "C" is wrong since the crew has isolated letdown, so the VCT is not heating up. "D" is correct since service water cools the charging pump cooling water heat exchangers.

With the plant initially at full power, the following sequence of events occurs:
- 1. The crew enters EOP 3503 "Shutdown Outside Control Room due to toxic gas in the control room.
- 2. The crew completes all EOP 3503 control room steps prior to evacuating.
Assuming that no operator action has been taken to control RCS temperature, at what temperature should RCS Tave stabilize?
A. 553 0 F B. 557 0 F C. 561°F D. 567 0 F Proposed Answer: C Explanation (Optional):
EOP 3503 has the operators close the MSIVs prior to the evacuation, if possible. The closure of the MSIVs will isolate the main steam header, preventing the use of the condenser steam dump vales. RCS temperature will begin to increase above the no-load Tave value of 557F ("A" and "B" incorrect).
"C" is correct and "D" is wrong, since operators close MSIVs rather than actuate MSI, so Atmospheric Relief valves are available These valve have a normal setpoint of 1125 psig, so RCS temperature is controlled at 561°F (sat. temp. for 1125 psig).

- 1. A large break LOCA occurs.
- 2. The reactor trips and safety injection actuates.
- 3. The crew manually actuates CDA at E-0, step 12, since CTMT pressure is 37 psia and Quench Spray pumps are not running. Both Quench Spray pumps will not start.
- 5. A PEO is dispatched to the ESF building to realign RSS pump "C", using EOP 35 FR-Z.1, Attachment "A".
How will EOP 35 FR-Z. 1, Attachment "A" align the "C" RSS pump to provide CTMT spray?
A. The suction is aligned from the RWST, and the discharge to the RSS CTMT spray ring.
B. The suction is aligned from the CTMT sump, and the discharge to the RSS CTMT spray ring.
C. The suction is aligned from the RWST, and the discharge to the QSS CTMT spray ring.
D. The suction is aligned from the CTMT sump, and the discharge to the QSS CTMT spray ring.
Proposed Answer: A Explanation (Optional):
EOP 35 FR-Z.1 Attachment "A" aligns an RSS pump to take a suction on the RWST and discharge through its CTMT spray ring. This effectively converts one RSS pump into a QSS pump. CTMT sump level may be inadequate for taking a suction on the CTMT sump ("B" and "D" wrong), and the RSS pump will discharge through its own spray ring ("C" and "D"wrong).

"A" is correct, since per the ERG background document, the note prior to step one informs the operator not to perform the procedure because ECA-3.2 reduces ECCS flow and subcooling, while performing C.3 would do the opposite. "B" is wrong, since it does not agree with the background document, and the PORVs are only used in ECA-3.2 if normal spray is not available. "C" is wrong, since FR-C.3 removes letdown from service. "D" is wrong, since FR-C.3 does not have a cooldown step.

PURPOSE: To inform the operator that this guideline is not intended to be used while performing the saturated recovery actions included in ECA-3.2 BASIS:
Guideline FR-C.3 directs a reestablishment of RCS subcooling, injection flow. This is inconsistent with actions specified via safety reduce RCS subcooling via SI flow reduction in order to in ECA-3;2 which minimize primary-to secondary leakage for a steam generator tube rupture.
Therefore, guideline FR-C.3 shQuld not be used if ECA-3.2 is in effect.

With the plant in MODE 5, 3CHS-RE69 goes into the ALERT condition. The RO reports that CTMT area radiation monitors are showing an increasing trend.
For these conditions, AOP 3553 "High RCS Activity" cautions the operators to consider restricting access to the ESF building due to the potential for increased radiation levels.
Why does AOP 3553 have this caution?
A. The potential exists for leakage from CTMT into SLCRS areas.
B. Increased radiation levels in CTMT will raise radiation levels in buildings adjacent to CTMT.
C. If Excess Letdown is in operation, RCS activity may be transported through the CVCS system.
D. If the RHR system is in operation, RCS activity may be transported through the RHR system.
Proposed Answer: D Explanation (Optional):
Caution prior to step 1 of the procedure makes the statement for ALARA considerations for the ESF if RHR is operating, since the system is transporting RCS fluid and, therefore, increased radiation levels would be expected. "A" and "B" are plausible, since CTMT area monitors have shown an increasing trend. "C" is plausible since CVCS provides a flowpath for RCS water outside of CTMT.

INITIAL CONDITIONS:
S The plant has been on line for 400 days.
S Reactor power is 80%
0 Bank D rods are at 180 steps 0 Control Bank D starts to withdraw automatically with no demand signal present.
Per AOP 3552 "Malfunction of the Rod Drive System", operators place rods to MANUAL, and rod motion stops. The STA determines that approximately 100 pcm of reactivity was added.
Which of the following describes how neutron flux responded, assuming no further operator action?
A. Power will increase promptly to about 85% and remain there.
B. Power will increase promptly to about 85%, and then slowly ramp up to the PR Hi Flux Hi setpoint resulting in a reactor trip.
C. Power will promptly increase to about 85% and subsequently return to about 80% power with an elevated Tave.
D. Power will promptly increase to about 85% and subsequently return to about 80% power with Tave returning to normal.
Proposed Answer: C Explanation (Optional):
The value for MTC will be fairly large due to time in core life. When the rods withdraw, reactor power will increase, and Tave will increase since steam demand has not changed. The temperature rise will add negative reactivity to compensate for the worth of the rods (MTC),
reducing power ("A" and "B" wrong). Final condition will be close to original power with elevated Tave ("C" is correct, "D" is wrong. An overpower reactor trip will not occur, since power defect from 80% to 100% power is approximately 400 pcm, and the rods only added 100 pcm.

The plant trips due to a loss of offsite power. The crew is currently in ES-0. 1, "Reactor Trip Response."
Why will the crew start the SBO diesel?
A. To power SBO auxiliaries.
B. To power selected "A" Train non-emergency loads , such as the plant process computer.
C. To power selected "B" Train non-emergency loads, such as an instrument air compressor.
D. To power Primary Grade Water Pumps from either train, allowing for RCS makeup.
Proposed Answer: A Explanation (Optional):
SBO diesel installed to cope with loss of all AC power event, postulated to last eight (8) hours.
With the loss of offsite power, loss of the EDGs results in a station black out. If the SBO diesel battery is depleted, the SBO diesel cannot perform the intended function to supply a source of AC power for an eight (8) hour period.
"B", "C", and "D" are plausible, since non-emergency busses have been lost, and the SBO diesel will be loaded later on in ES-0.2 since running the SBO diesel unloaded for an extended period of time allows buildup of combustibles in the SBO diesel exhaust.

PLANT CONDITIONS:
- A small break LOCA has occurred
- The crew is in ES-I.2, "Post-LOCA Cooldown and Depressurization"
- An RCS cooldown has been initiated by dumping steam to the atmosphere.
- The crew is preparing to start the SI reduction sequence.
Which of the following statements describes the optimum RCP configuration, and the basis for this configuration?
A. No RCPs should be running, to minimize RCS inventory loss during the cooldown, and reduce subcooling requirements for the SI reduction sequence.
B. No RCPs should be running, to protect RCPs from damage since #1 seal requirements are expected to be lost.
C. One RCP should be running to provide improved RCS pressure control, yet minimize RCS heat input.
D. One RCP should be running, to provide RCS mixing while reserving the other RCPs for future use while operating under voided RCS conditions.
Proposed Answer: C Explanation (Optional):
"C" is correct, since forced coolant flow is the preferred mode of operation to allow for normal RCS cooldown and provide PZR spray. All but one should be stopped to minimize heat input into the RCS. "A" is wrong since subcooling requirements are greater without an RCP running. "B" is wrong since RCPs are stopped later in the procedure due to seal requirements when preparing to place RHR in service. "D" is wrong, since subcooling requirements are checked prior to starting any RCPs. "A" is plausible, since RCP trip criteria require tripping the RCPs prior to cooldown initiation. "B" is plausible since seal requirements will be lost later in the cooldown. "D" is plausible, since RCS voiding is a basis for stopping an RCP in FR-C.2 Technical Reference(s): ES-1.2, steps 12 and 13. (Attach if not previously provided)

0 One charging pump has been stopped 0 All other high head ECCS pumps are running 0 No RCPs are running 0 Pressurizer level is 30%
Sufficient subcooling exists and the operator stops the "A" Safety Injection pump. Immediately after stopping the pump, RCS pressure begins to decrease.
What action should the crew take immediately in response to the decreasing RCS pressure?
A. Manually reinitiate Safety Injection.
B. Restart the "A" Safety Injection pump to restore RCS pressure to its previous value.
C. Restart the "A" CHS pump to restore RCS pressure to its previous value.
D. Monitor RCS subcooling and pressurizer level to ensure these parameters stabilize above their SI reinitiation values.
Proposed Answer: D Explanation (Optional):
"D" is correct, since after stopping any SI pump, RCS pressure should be allowed to stabilize or increase before stopping another SI pump.
The basis for this is that after the SI pump is stopped, RCS pressure may decrease rapidly to a new equilibrium value where the reduced SI flow again matches leakage from the RCS. The criteria for stopping the next SI pump has been calculated assuming steady state conditions.
Hence, to ensure that these criteria are appropriate, RCS pressure and subcooling should be allowed to stabilize or increase before stopping additional SI pumps.

A. This ensures that the P/A converter will send the proper rod height data to the RIL circuitry.
B. This ensures that the rod is withdrawn to the proper height with a proper group step counter indication.

- 3. The crew enters EOP 3509 "Loss of All Charging Pumps".
Which of the following events would require the crew to trip the reactor, and why?
A. The "C" charging pump can not be aligned for service, since there is no method available to add inventory to the RCS.
B. The "C" charging pump can not be aligned for service, since there is no method available to add boron to the RCS.
C. The "B" RPCCW Pump trips, since cooling is lost to the seal return heat exchanger, with the potential for the release of radioactive steam to the auxiliary building.
D. The "B" RPCCW Pump trips, since the potential exists for degradation of the RCP seals, resulting in a significant increase of RCS leakage.
Proposed Answer: D Explanation (Optional):
"D" is correct, and "A" and "B" are wrong, since the reactor must be tripped if thermal barrier cooling is lost (RPCCW pump tripped) AND seal injection flow is less than 6 gpm (no charging pump is running). "C" is wrong since the major concern for a loss of seal injection and thermal barrier cooling is degraded seal performance. "C" is plausible since a trip criteria is met, and the rad release concern is the basis for isolating the seal return line on a loss of all AC power. "A" and "B" are plausible since EOP 3506 attempts to line up the swing charging pump for service, and requires an orderly plant shutdown if unsuccessful.

"* A reactor startup is in progress
"* Control banks are being withdrawn
"* Source Range counts: N31 = 1500 cps N32 = 1600 cps A faulty power supply causes significant instrument power voltage fluctuations to Source Range channel N31.
Which of the following describes the effect of the power supply voltage fluctuations on the plant?
A. Instrument voltage changes will result in proportional changes in indicated count rate. The reactor will trip on high source range flux.
B. Instrument voltage changes will result in proportional changes in indicated count rate. The reactor will not trip since the source range high flux trip is already blocked.
C. Instrument voltage changes will not result in changes in indicated count rate, since the detector operates in the ion chamber region. The crew will continue the startup.
D. Instrument voltage changes will not result in changes in indicated count rate, since the detector operates in the ion chamber region. The crew will stop the startup and drive rods in.
Proposed Answer: A Explanation (Optional):
"C" and "D"are wrong since the source ranges operate in the proportional region of the gas amplification curve. The Source Range high flux trip will actuate when counts exceed 105 cps on 1/2 channels. Since the coincidence is 1/2, the reactor will trip. "A" is correct, and "B" is wrong, since source ranges are blocked above P-6, which comes in at 1010 amps in the intermediate range, which is above 104 cps.

The crew has responded to a Steam Generator tube leak that does not require Safety Injection actuation.
Which of the following conditions would meet the AOP 3576 "Steam Generator Tube Leak" criteria of verifying primary to secondary leakage?
A. Chemistry sample indicates activity equal to twenty gallons per day primary to secondary leakage.
B. Chemistry sample indicates unquantified presence of primary to secondary leakage.
C. Alarm status of air ejector radiation monitor 3ARC-RE21 and auxiliary feedwater pump terry turbine exhaust radiation monitor 3MSS-RE79 not normal.
D. Alarm status of blowdown radiation monitor 3SSR-RE08 and main steam line radiation monitor 3MSS-RE76 not normal.
Proposed Answer: D Explanation (Optional):
Note before step 3 of AOP 3576 states that leakage can be verified with 2 out of 3 criteria met.
Alarm status of blowdown and main steam line radiation monitor not normal are 2 of the possible 4 criteria (D correct). "A" is wrong, since this is similar to step 3 RNO but correct value is >30 gpd not 20 gpd. "B" is wrong and plausible since this is 1 of the criteria needed, and 2 are required.
"C" is wrong, and plausible since two criteria are listed, but 3MSS-RE79 is not one of the 4 criteria.

With the plant at 100% power, a "TDFW PP A/B EAP CONST SIG LOST" annunciator comes in on MB5. The crew references the ARP and the US directs the BOP to take manual control of the "A" TDMFP.
How is speed control for the selected TDMFP returned to the operator?
A. The TDMFP master speed controller is taken to MANUAL and used to adjust TDMFP speed.
B. The DAHL controller for the "A" TDMFP (3FWS-SK46A) is taken to MANUAL and used to adjust TDMFP speed.
C. The Manual Speed Controller (3TFC-M1A) is lowered until TDMFP speed starts to decrease, and then the DAHL controller (3FWS-SK46A) is taken to MANUAL and raised to the high speed stop.
D. The Manual Speed Controller (3TFC-MIA) is lowered until TDMFP speed starts to decrease, and the hydraulic jack for the "A" TDMFP is placed to "ON".
Proposed Answer: D Explanation (Optional): The specified annunciator comes in when the Westinghouse speed control signal is lost. This locks the EAP controllers for both TDMFPs at the "last called for" signal. "A" and "B" are wrong, since both of these require the EAP controller to respond, either to the input from the master controller, or from manual control. "D" is correct, and "C" is wrong, since TDMFP speed is controlled by the lower speed setting of either the DAHL, or the Manual Speed Controller, and the DAHL cannot be raised out of the way manually. The hydraulic jack blocks the hydraulic bleed path from the EAP positioner, driving it to the high speed stop.

"* Hot leg temperatures: 545 0 F
"* Containment pressure: 17 psia
"* Containment temperature: 140°F
"* CTMT radiation: 5 x 10' R/hr
"* The crew has transitioned to FR-H.1 "Loss of Heat Sink".
The BOP operator reports that Steam Generator wide range levels are:
"* SG "A": 55%
"* SG "B": 56%
"* SG "C": 60%
"* SG "D": 54%
Which of the following actions should be taken?
A. Attempt to establish AFW feedwater flow to at least one steam generator.
B. Attempt to establish main feedwater flow to at least one steam generator.
C. Return to E-1 "Loss of Reactor or Secondary Coolant".
D. Stop all Reactor Coolant Pumps and establish RCS bleed and feed.
Proposed Answer: D Explanation (Optional):
Adverse containment exists based on high CTMT radiation, therefore WR level for feed and bleed is 59% in any 3 steam generators. "A" and "B" are plausible, since these are the mitigation strategies of FR-H.1 if bleed and feed criteria is not met. "C" is plausible, since step 1 of FR-H.1 returns the crew to E-1 if RCS pressure is not greater than ruptured SG pressure.

What is the purpose of the upload limit interlock on the new fuel elevator?
A. Prevent dropping a new fuel assembly from excessive heights should the elevator cable fail.
B. Prevent raising an irradiated fuel assembly so that the minimum required depth of water shielding is maintained.
C. Prevent raising the elevator guide rollers out of the water, since the rollers are water lubricated.
D. Prevent raising the elevator when either cable binding is taking place or an obstruction is in the cart's path.
Proposed Answer: B Explanation (Optional):
"B" is correct, since the upload limit interlock stops upward motion of the elevator when loaded with a fuel assembly. Handling equipment used to raise and lower spent fuel also has a limited maximum lift height so that the minimum required depth of water shielding is maintained. "A" and "C" are plausible, since they deal with reasons for limiting upward travel. Also, lubrication is a concern when raising the rollers above existing water level. "D" is plausible, since it deals with limiting travel when load is sensed.

The following sequence of events occurs:
- 1. The reactor trips due to an inadvertent Main Steam Isolation signal.
- 2. While recovering in EOP 35 ES-0.1 "Reactor Trip Response", the crew transitions to FR-H.2 "Response to High SG Pressure".
Current conditions are as follows:
"* "B" SG pressure is 1250 psig.
"* "B" SG level is 65% narrow range.
"* Tave is 570 0 F.
"* All SG safety valves are closed.
"* The crew was not successful in dumping steam from the "B" SG.
Based on current conditions, what method will the operators use to reduce pressure in the "B" SG?:
A. Initiate blowdown flow from the "B" SG.
B. Feed the "B" SG with maximum auxiliary feed flow.
C. Dump steam from the atmospheric dump valves on the "A", "C", and "D" SGs.
D. Dump steam from the atmospheric dump bypass valves on the "A", "C", and "D"SGs.
Proposed Answer: D Explanation (Optional):
The quickest way to remove heat from the SG is to dump steam. ("D" is correct)
"A" is wrong since blowdown will remove a minimum amount of heat. "A" is plausible since increasing blowdown is an action to recover from a high SG level, but if high level exists, the crew would have transitioned to FR-H.3.
"B" is wrong since FR-H.2 cautions against feeding the SG until a steam release path is available.
"B" is plausible since feed will cool the SG. "C" is wrong since the atmospheric dump valves will not open due to the MSI signal. "C" is plausible since dumping steam would cool the "B" SG.

Proposed Answer: B Explanation (Optional):
"B" is correct, since below 120 steps, bank "D" rods are inserted too far for reduce flux in the upper portion of the core. "A" and "C" are wrong, since RIL and "Rod Lo" setpoints are variable, and operators will continue the downpower whether or not these setpoints are reached.

ES-401 Sample Written Examination Form ES-401-6 Question Worksheet "ExaminationOutline Cross-reference: Level RO 45 SRO 45 Tier # 2 2 Group # 1 1 K/A # 015.A1.03 Importance Rating 3.7 3.7 Proposed Question:
Initial conditions:
- 1. The current 4 minute average calorimetric output is 3411 MWth based on a steam flow calculation.
- 2. Feed pressure instrument 3FWS-P37B needs to be removed from service for 3 days for a cable upgrade.
- 3. The crew desires to maintain the calorimetric as a calculated value, if possible, rather than allow it to auto-shift to a value based on NIS indications.
- 4. The highest reading NIS channel reads 100.1%. The average of the 4 NIS channels is 100.0%.
Using the attached copy of Attachment 7 of SP31002 "Plant Calorimetric", what actions will the crew take prior to allowing the channel to be removed from service?
A. Reduce power until the highest reading NIS channel is reading _<100%, since the computer will no longer display a value for thermal power.
B. Verify the average of the 4 NIS channels is reading <100% prior to removing the channel from service, since the auto-swap to NIS can not be avoided.
C. Reduce power by about 2% and then force the calorimetric to a feed flow calculation prior to removing the channel from service, since feed flow calorimetric normally reads higher than steam flow calorimetric.
D. Force the calorimetric to a feed flow calculation prior to removing the channel from service.
Power reduction should not be required, since feed flow calorimetric normally reads lower than steam flow calorimetric.
Proposed Answer: B Explanation (Optional):
3FWS-P37B is utilized by both the steam flow and feed flow calculation, so the crew cannot force a feed flow calculation prior to the calibration ("C" and "D" wrong). "C" and "D" are plausible since other channels will only auto-swap the calorimetric to NIS value if in one of the two (steam or feed) calculations. "C" and "D" are also plausible since feed flow calorimetric reads higher than steam flow calorimetric due to the phenomena of feed venturi fouling. "B" is correct, and "A" is wrong, since OP 3204 only requires maintaining the highest NIS channel <100% if the computer thermal power display is unavailable, and thermal power is still indicated, based on a conversion of NIS values.

"A" is wrong since two CAR fans should be in operation during normal plant operations. "B" is wrong an "C" is correct since it is preferred not to run CAR fans "A" and "B" together, since PZR cubicle temperature increases without the "C" CAR fan in operation. "D" is wrong since running 3 CAR fans simultaneously causes a high backpressure and the fans will trip on overcurrent.

INITIAL CONDITIONS:
- Power is being increased from 90% to 100% in accordance with OP-3204.
- Both turbine driven feedwater pumps are operating.
- Two condensate pumps are in service.
- 6 condensate demineralizers are in service. A malfunction has caused the recirc valve for the "B" TDMFW pump to travel to the full open position.
Without operator action, what impact might this failure have on plant conditions?
A. SG Lo-Lo level resulting in a reactor trip.
B. Lowering demineralizer d/p resulting in degrading SG chemistry.
C. Standby condensate pump start, preventing a reactor trip.
D. Auto start of the MDFW pump, preventing a reactor trip.
Proposed Answer: A Explanation (Optional):
Millstone 3 OE has shown that the maximum number of condensate demineralizers should be available to provide adequate feed pump suction flow when increasing feed flow, since condensate pump flow is limited by the number of demins in service. The recirc valve opening will cause condensate flow to increase by 5,400 gpm. Without operator action to start the standby condensate pump or open the demin bypass valve, the added condensate flow due to recirc flow back to the condenser will cause demineralizer dip to increase ("B" incorrect), and suction pressure to the feed pumps to decrease. The feed pump speed will increase, attempting to restore Feed Reg Valve DP, further lowering feed pump suction pressure. After 30 seconds the feed pumps will trip on low suction pressure ("A" correct). The MDFW pump may auto start on low discharge pressure (less than 955 psig), but this will aggravate the low suction pressure condition
("D" incorrect).

With the plant initially at 100% power, a significant feed heater level transient results in HI-HI levels in all 3 first point feed heaters. Extraction steam isolates to all 3 first point heaters.
Assuming the reactor does not trip, what will be the initial effect on indicated narrow range SG levels, and on actual reactor power?
A. SG NR levels will increase and actual reactor power will increase.
B. SG NR levels will increase and actual reactor power will decrease.
C. SG NR levels will decrease and actual reactor power will increase.
D. SG NR levels will decrease and actual reactor power will decrease.
Proposed Answer: C Explanation (Optional):
"C" is correct since loss of feed preheating will add colder water to the SGs, reducing boiling, resulting in "shrink" ("A" and "B" wrong) and also resulting in a drop in RCS Tcold. The drop in Tcold adds positive reactivity, causing reactor power to increase ("B" and "D" wrong).

A. None.
B. The Turbine Driven Auxiliary Feedwater Pump only.
C. Both Motor Driven Auxiliary Feedwater Pumps only.
D. All three Auxiliary Feedwater Pumps.
Proposed Answer: C Explanation (Optional):
Both MDAFW pumps will auto-start on the SIS signal. The TDAFW pump starts on Lo-Lo level in 2/4 SGs, and since initial power was low, the effects of shrink will be minimal, and only the faulted SG will lose narrow range level. "A" is plausible, since initial power level was low, minimizing shrink. "B" and "D" are plausible since a Safety Injection signal actuated.

"B" is wrong, since ECCS reinitiation criteria (per the foldout page is pressurizer level less than 16%) does not apply until SI has been terminated. "C" is wrong, since RCS pressure is above the adverse CTMT setpoint of 500 psia. "D" is wrong, since RCS pressure is above the adverse CTMT setpoint and CTMT radiation would still be below Adverse CTMT value.

With the plant initially at 100% power, a small cold leg break loss of coolant accident has occurred.
Current conditions are as follows:
"* No CHS or SIH pumps can be started.
"* RCS pressure has stabilized at 1200 psia.
"* The Pressurizer is empty.
Why is it important that an operator controlled cooldown of the RCS is commenced expeditiously?
A. The Fuel Clad temperature limits will be challenged.
B. The Containment pressure limits will be challenged.
C. The RCS pressure limits will be challenged.
D. RCS pressure control has been lost.
Proposed Answer: A Explanation (Optional):
Inadequate heat removal exists out the cold leg break, reactor vessel heat maintains RCS pressure above the accumulator and RHR pump shutoff head. All the while inventory continues to be lost, and deep core uncovery will occur unless an operator controlled cooldown reduces RCS pressure to accumulator and RHR pump injection pressures ("A" correct).

With the plant at 100% power, a pressurizer code safety valve inadvertently lifts and remains partially open.
The following indications exist:
"* Pressurizer pressure is 2235 psig and DECREASING.
"* Tave is on program.
"* PRT pressure is 20 psia and INCREASING The RO monitors PORV tail pipe temperature on MB4.
What should tail pipe temperature be indicating?
A. 230°F B. 270°F C. 300°F D. 650°F Proposed Answer: A Explanation (Optional):
"A" is correct because the enthalpy of the saturated steam in the PZR vapor space does not change as it passes through a safety valve, resulting in a temperature indication corresponding to the pressure in the PRT. The Mollier diagram shows that enthalpy of the PZR steam is approximately 1120 BTU/Ib. Move across (left to right) to the PRT pressure, demonstrating that the steam will be saturated at PRT pressure. Follow the constant pressure line up to the saturation curve, which reads about 230'F. "B" is plausible, since this would be the approximate temperature based on saturation pressure (1400 psia) for the current Tave. "C" is plausible, since this is the temperature obtained if the candidate incorrectly assumes a constant entropy process.
"D" is plausible, since this is the answer if the student incorrectly assumes a constant temperature process (TMI).

A normal shutdown from full power is being performed.
At 40% power, Intermediate Range Channel IR-35 fails high.
If no operator action is taken to address the failed instrument, how will the shutdown be affected?
A. The reactor trips immediately, and both Source Range channels will have to be manually energized.
B. The reactor trips immediately, and both Source Ranges will automatically energize at the proper time.
C. The reactor will trip when power is reduced below 10%, and both Source Range channels will have to be manually energized.
D. The reactor will trip when power is reduced below 10%, and both Source Ranges will automatically energize at the proper time.
Proposed Answer: C Explanation (Optional):
The IR trip is blocked until power decreases below 10% power (P-10) on % PRNI channels "A" and "B" wrong). The failed IR channel causes the trip since it is >25% equivalent. With a high failure of IR N-36, the Source Range instruments will not automatically reenergize since P-6 requires both IR channels to be <5x10-10 amps ("C" correct, "D" wrong).

Proposed Answer: B Explanation (Optional):
"B" is correct since the control signals going to the controller are electrically isolated from the protection circuits.

A CDA occurred and the crew is progressing through the EOP network. The CTMT Recirc (RSS) pumps have just started, and the RO is verifying that equipment is in the desired lineup.
What should be the position of the RPCCW heat exchanger service water inlet isolation valves (3SWP*MOV50A/B), and the service water inlet valves to the containment recirc coolers (3SWP*MOV54A/B/C/D)?
A. Both the RPCCW heat exchanger service water inlet isolation valves and the service water inlet valves to the containment recirc coolers should be OPEN.
B. The RPCCW heat exchanger service water inlet isolation valves should be OPEN and the service water inlet valves to the containment recirc coolers should be CLOSED.
C. The RPCCW heat exchanger service water inlet isolation valves should be CLOSED and the service water inlet valves to the containment recirc coolers should be OPEN.
D. Both the RPCCW heat exchanger service water inlet isolation valves and the service water inlet valves to the containment recirc coolers should be CLOSED.
Proposed Answer: C Explanation (Optional):
"C" is correct, since on a CDA, the RPCCW heat exchanger service water inlet isolation valves receive a CLOSE signal, to prevent excessive flow for the service water pumps.
The service water inlet valves to the containment recirc coolers receive an OPEN signal to provide cooling to the CTMT sump water being recirculated. "A" is plausible, since this also supplies cooling to the RSS heat exchangers. "B" and "D" are plausible since there is a 3 minute time delay prior to 3SWP-MOV54C opening, but since the RSS pumps are running, at least 11 minutes has passes since the CDA actuated.

Initial conditions:
"* The plant is in MODE 6.
"* Fuel Movement has been suspended due to problems with the refueling machine.
"* The Fuel pool transfer canal gate valve is open.
"* The CTMT access hatch is open.
"* One hour ago, the crew started up the CTMT Purge System, with the "A" Train supply HVU (3HVR-HVU1A) and exhaust fan (3HVR-FN4A) running.
Power has just been restored to the "B" Train, and the crew is preparing to start the second CTMT Purge Exhaust fan (3HVR-FN4B).
According to the precautions in OP 3313F "Containment Purge Air", what potentially adverse effect will result from starting the second CTMT purge exhaust fan?
A. The CTMT Purge System sheet metal ductwork will be damaged in the Auxiliary Building.
B. CTMT Purge System flowrates will exceed the capacity of the air handling unit to maintain air temperature.
C. Level in the spent fuel pool and refueling cavity will change.
D. CTMT air will start flowing out the CTMT hatch into the Auxiliary Building.
Proposed Answer: C Explanation (Optional):
"C" is correct, since changing the status of the CTMT Purge system will alter the DP between CTMT and the fuel building. "A" is wrong, since ductwork damage is only a problem when the CTMT is at a vacuum. "A" is plausible, since sheet metal ductwork damage is possible, and has happened in the past at Millstone 3. "B" is wrong, since the HVU is expected to handle the air temperature requirements with two exhaust fans running. "B" is plausible, since air flow will increase through the HVU.

MNPS-3 FSAR Normal reactor control systems and engineered safety systems are not required to "function. The reactor protection system is assumed to be operable; however, ila)I is not encountered for any case due to the error allowances assumed in a reactor trip the set points. No single active failure will prevent the reactor protection system from performing its intended function.
The cases which assume automatic rod control are analyzed to ensure that the worst case is presented. The automatic function is not required.
Results Figures 15.1-3 through 1 5.1-6 illustrate the transient with the reactor in the manual control mode. As expected, for the minimum moderator feedback case there is a slight power increase, and the average core temperature shows a large decrease.
This results in a DNBR which increases above its initial value. For the maximum moderator feedback, manually controlled case there is a much larger increase in reactor power due to the moderator feedback. A reduction in DNBR is experienced but DNBR remains above the safety analysis limit.
Figures 15.1-7 through 1 5.1-10 illustrate the transient assuming the reactor is in the automatic control mode. Both the minimum and maximum moderator feedback cases show that core power increases, thereby increasing the coolant average temperature and pressurizer pressure above their initial value. For both of these cases, the minimum DNBR (9I-i*)j remains above the safety analysis limit.
"For all cases, the plant rapidly reaches a stabilized condition at the higher power level.
Normal plant operating procedures would then be followed to reduce power. Note that due to the measurement errors assumed in the set points, it is possible that reactor trip could actually occur for the automatic control cases. The plant would then reach a stabilized condition following the trip.
The excessive load increase incident is an overpower transient for which the fuel tempera tures rise. Reactor trip does not occur for any of the cases analyzed, and the plant reaches a new equilibrium condition at a higher power level corresponding to the increase in steam flow.
Since DNB does not occur at any time during the excessive load increase transients, the ability of the primary coolant to remove heat from the fuel rod is not reduced. Thus, the fuel cladding temperature does not rise significantly above its initial value during the transient.
The calculated sequence of events for the excessive load increase incident is shown in Table 15.1-1.
15.1.3.3 Conclusions The analysis presented above shows that for a 10 percent step load increase, the DNBR
- -qI-I)l remains above the safety analysis limit; the design basis for DNBR as described in Section 4.4 is met. The plant reaches a stabilized condition rapidly following the load increase.

The plant is at 100 % power. All electrical systems are in their normal alignment.
Load Center 32T deenergizes due to a bus differential, and cannot be reenergized.
Which of the following describes the effects, if any, on the 125 VDC electrical distribution system?
A. No effect. The inverter 1 static switch will transfer VIAC-1 loads to the alternate source.
B. Battery 1 begins to discharge, but will stop discharging when swing charger 301A-3 is placed in service.
C. Battery 1 begins to discharge, because it is now supplying Battery Bus 301A-1 loads, while Inverter 1 continues to supply VIAC-1 from the rectifier.
D. Battery 1 begins to discharge, because it is now supplying both Battery Bus 301A-1 loads, and supplying VIAC-1 via the inverter.
Proposed Answer: D Explanation (Optional):
"D" is correct, since when 32T is lost, power is lost to the rectifier, the battery charger, and the swing battery charger ("B" and "C" wrong), causing battery 301A-1 to pick up the load on the DC bus. Automatic switchover to the alternate AC source only occurs if the output from the inverter is lost ("A" is wrong), so the battery will also supply VIAC 1 via the inverter. "A" is plausible, since this would occur on a loss of the inverter. "B" is plausible, since batteries 301A-2 and 301 B-2 have the swing charger powered from a different load center than their normal charger. "C" is plausible, since this would be the lineup if only the battery charger was lost.

- 6. Although power is available, attempts to start the Fuel Oil Transfer Pumps are unsuccessful.
How will the crew fill the "A" EDG Fuel Oil Day Tank?
A. Obtain maintenance department assistance and align hoses from the "B" train Fuel Oil Transfer Pump.
B. Place the 3EGS*PNLA control switch on MCC32-1T-3H to "start" and start the Fuel Oil Transfer Pumps from 3EGS*PNLA.
C. Mechanically align the system, and use Kirk keys to electrically align and operate 3EGF*P1 B, Fuel Oil Transfer Pump, from alternate power supply, 32-1T.
D. Mechanically align the system, and use Kirk keys to electrically align and operate 3EGF*PI D, Fuel Oil Transfer Pump, from alternate power supply, 32-1T.
Proposed Answer: D Explanation (Optional):
A wrong: Power is not available for the "B" fuel oil transfer pump.
B wrong: 3EGS*PNLA contains non-essential loads. This is plausible, since its control switch is on 32-1T, and it is operated when recovering in ECA-0.1.

"A" is incorrect because the "B" H2 Recombiner will not auto start.
"B" is incorrect because the H2 Building HVAC Equipment Room exhaust damper does not receive a close signal when HVZ*RE09A alarms.
"C" is incorrect because the "B" H2 Recombiner does not auto start and its exhaust damper does not auto open when HVZ*RE09A alarms.

If no operator action is taken during this event, which of the following conditions would always result in an automatic reactor trip?
A. The "A" and "B" circ water bay traveling screen DPs are 38 inches H20.
B. The "C" and "D" circ water bay traveling screen DPs are 38 inches H20.

D. The "B" and "D" circ water bay traveling screen DPs are 44 inches H20.
"ProposedAnswer: B Explanation (Optional):
A reactor trip will occur due to loss of condenser vacuum if two circ pumps trip in the same bay.
"B" is correct, and "A" is wrong, since the "A" and "B" circ pumps trip at 42 inches H20, while all the other circ pumps trip at 36 inches H20. The reason for this is that the "A" and "F" bays do not have service water pumps associated with them, and screen durability becomes the limiting component. "C" and "D" are wrong, since a reactor trip will occur only if the lost circ pumps are in the same bay.

The secondary rounds PEO reports an air leak on the instrument air ring header in the turbine building. The RO reports that instrument air header pressure is at 91 psig and decreasing slowly.
If the added capacity of the service air compressor is more than capable of compensating for the leak, how should service air header pressure respond prior to any local actions by PEO's?
A. SAS pressure will remain normal, since local actions by a PEO are required locally to both open 31AS-AOV14 to supply service air to instrument air, and close 3SAS-AOV33.
B. SAS pressure will remain normal, since 31AS-AOV14 opens automatically at 85 psig, but local PEO actions are required to close 3SAS-AOV33.
C. When IAS header pressure lowers to 85 psig, SAS pressure will start to drop as both 31AS AOV14 and 3SAS-AOV33 realign. SAS pressure will start to recover again when IAS header pressure increases to 103 psig.
D. When IAS header pressure lowers to 85 psig, SAS pressure will start to drop as both 31AS AOV14 and 3SAS-AOV33 realign. SAS pressure will continue to drop to zero psig, since both valves will remain in their new positions.
Proposed Answer: C Explanation (Optional):
Pressure switch 31AS-PS14, which senses lAS common header pressure downstream of the IAS receivers, will cause AOV14 to open, and simultaneously cause AOV33 to close when pressure lowers to 85 psig ("A" and "B" wrong). Additionally, when IAS header pressure increases to 103 psig, PS14 will automatically realign the AOV's to their normal positions, and pressure will again start to decrease since the leak has not been isolated ("C" is correct and "D" is wrong).

The unit has experienced a Large Break LOCA and has worked through the EOP network and is currently aligning the RHR and Recirculation Spray Systems for Cold Leg Recirculation.
Why should the RSS pumps be operated for two minutes prior to opening RHR isolation valves 3RSS*MV8837A and 3RSS*MV8837B?
A. To prevent injecting air into RSS coolers.
B. To prevent runout of the RSS pumps.
C. To prevent injecting air into RHR pumps.
D. To prevent injecting air into SI and Charging pumps.
Proposed Answer: D Explanation (Optional):
"D" is correct, since the RSS pumps utilize a portion of the RHR piping to supply the suctions of the Charging and SIH pumps during the recirculation phase. Opening one RHR cold leg injection valve will provide the flowpath from RSS into the RCS and potentially, air introduction. "A & B" are wrong, since they are upstream of the valves 3RSS*MV8837A and 3RSS*MV8837B. "C" is wrong, since while these valves connect to the RHR system, the cross-connection does not involve the RHR pumps.

With the plant operating normally at 100% power, the following sequence of events occurs:
- 1. The "A" RPCCW pump trips.
- 2. The primary rounds PEO is directed to align the "C" RPCCW pump and heat exchanger to the "A" train.
What, if anything, is required to provide a breaker for the "C" RPCCW pump breaker cubicle?
A. Nothing is required at the breaker cubicle. The swing pump breaker is normally aligned to the "A" train and is already racked up in cubicle 34C10-2.
B. Nothing is required at the breaker cubicle. All actions are completed at the CCP transfer switch to realign the "C" RPCCW pump to either train.
C. The breaker will need to be moved from the "B" train cubicle (34D9-2) and racked up into the "A" train cubicle (34C10-2).
D. The "A" RPCCW pump breaker will need to be racked down from breaker cubicle 34C9-2 and racked up into breaker cubicle 34C10-2.
Proposed Answer: C Explanation (Optional):
"C" is correct, and "A" is wrong since the breaker is normally already racked up into the 'B' train cubicle. "D" is wrong, the swing pump has its own separate breaker. "B" is wrong since the transfer switch is necessary to prevent cross-tying busses 34C and 34D, but you still need a breaker installed in one of the swing pump's cubicles. "A" is plausible since the swing pump will be aligned to one train or the other. "B" is plausible since the CCP transfer switch must be operated when aligning the swing pump to the other train. "D" is plausible, since this is how the swing Charging (CHS) pump breaker is operated.

Initial Conditions:
"* Reactor power is 60%
"* Steam Dumps are in AUTOMATIC in the STEAM PRESSURE MODE due to I&C testing on turbine impulse pressure instrument 3MSS-PT506.
"* Both TDMFPs are in service.
Main Steam Header Pressure instrument 3MSS-PT507 fails high.
Which of the following describes the initial response of the plant to the failure?
A. Feed Pump speed will INCREASE. Steam dumps will OPEN.
B. Feed Pump speed will DECREASE. Steam dumps will OPEN.
C. Feed Pump speed will INCREASE. Steam dumps will remain CLOSED.
D. Feed Pump speed will DECREASE. Steam Dumps will remain CLOSED.
Proposed Answer: A Explanation (Optional):
"A" is correct, since as PK507 increases, the sensed DP between steam pressure and feed pressure decreases. The Master Speed controller increases pump speed ("B" & "D" incorrect,).
Increasing steam pressure (failed PT507) is sensed by the steam dumps, causing them to open to attempt to maintain set pressure ( "C" & "D" incorrect).

With the plant initially at 100% power, a safety injection occurs. CTMT pressure has reached 20 psia and the crew is checking the ESF status panel at E-0, step 14. The following valves are all noted to be OPEN:
"* Service water supply to TPCCW 3SWP*MOV71A
"* Service Water supply to RPCCW 3SWP*MOV50A
"* Service water return from the "A" EDG 3SWP*AOV39A What action, if any, should the crew take regarding these three valves?
A. Leave all of the valves in their current positions.
B. CLOSE service water supply to TPCCW 3SWP*MOV71A.
C. CLOSE service water supply to RPCCW 3SWP*MOV50A.
D. CLOSE service water return from the EDG's 3SWP*AOV39A.
Proposed Answer: A Explanation (Optional):
CDA has not actuated, since CTMT pressure has not reached 23 psia. "B" is wrong, since SWP*MOV71 is normally open and shuts on CDA, LOP and SWP low pressure. "C" is wrong since MOV50A is normally open and closes on a CDA. "D" is wrong since AOV39A is normally closed and opens on CDA/LOP or SIS. Therefore, all three valves should be open after SIS ("A" is correct). The distractors are plausible, since all 3 valves are operated by ESFAS signals.

Proposed Question:
The Plant is in Mode 3 with a cooldown in progress.
The following parameters exist:
- Pzr Water Temperature: 450°F
- RCS Water Temperature: 350°F
- Pzr Level as read on RCS-L1462 (Cold Calibrated): 40%
Using the attached copy of OP 3208, Attachment 2, which of the following approximates what the Hot Calibrated Pzr level Channels should be reading?
A. 35%
B. 40%
C. 45%
D. 50%
Proposed Answer: D Explanation (Optional):
OP3208 section 4.2.12 Caution indicates that the Hot Calibrated channels always read higher than the Cold Calibrated channels. Using Attachment 2, it can be determined that actual Pzr level is 45%. Since the Hot Calibrated channels are calibrated for Normal Operating Temperatures, and the Pressurizer temperature is lower than normal, the Hot Calibrated channels are reading higher than actual ("D" correct). "A" is plausible, since this is the answer ifthe candidate goes from PZR temperature up to actual level of 40% on the graph, and over to indicated level on the vertical axis.
"B" is plausible, since Cold Cal reads 40%. "C" is plausible since this approximates the actual level for a Cold Cal reading of 40% at this PZR temperature.

"* Turbine & Rx Power are equal At how many steps per minute inward should Control Bank "ID" rods be moving?
A. 8 spm B. 32 spm C. 40 spm D. 48 spm Proposed Answer: C Explanation (Optional):
Rods move at a minimum of 8 and a maximum of 72 spm. An error of 2 degrees will cause the minimum (8 spm) motion. Speed ramps from 3 to 5 degrees. At 4 degrees, rod speed will be half way or 32 spin plus the 8 they start at, therefore the rod speed is 40 spm. All answers are plausible, since they are in the inward direction, and they are bounded by rod control's minimum and maximum speeds.

"* RCS boron concentration is 900 ppm
"* Boric acid tank boron concentration is 6850 ppm
"* 3CHS-FK1 10, BA Makeup flow controller is set at 2.35 turns A manual makeup to the VCT is in progress per OP 3304C "Primary Makeup and Chemical Addition", section 4.3, "Aligning for Manual Makeup".
Using OP 3304C Attachment 7, attached to the back of the exam, how will the plant respond to the manual makeup?
A. RCS temperature will remain stable. Rods will not move.
B. RCS temperature decreases. Rods will not move.
C. RCS temperature decreases, and rods move out to compensate.
D. RCS temperature increases, rods move in to compensate.
Proposed Answer: D Explanation (Optional):
Desired flow is 10.51 gpm. 0 to 40 gpm corresponds to 0 to 10 turns on 3CHS-FK110. Solving for "X" in the equation X/10 = 10.51/40 provides a desired pot setting of 2.63. Since the current pot setting is too low, a dilution will occur, causing Tave to increase, ("D" correct). "A"is plausible, since this is what would happen if the pot was set correctly. "B" and "C" are plausible, since this is what would happen if the pot was set too high. Rods would move out in this case, except for the fact that rods are at the C-1 1 position, which would prevent outward rod motion.

"* All safeguards equipment operated as designed, except for the "A" MDAFW pump, which can not be started.
"* "B" SG pressure is 450 psig and decreasing.

"* The crew is performing E-0, step 3 "Verify Power to AC Emergency Busses".
When can the BOP operator isolate AFW flow to the "B" SG?
A. Immediately.
B. Only after receiving direction from the SM/US.
C. Only after completing his immediate actions in E-0.
D. Only after narrow range level in at least one SG is >8%.
Proposed Answer: C Explanation (Optional):
"C" is correct, and "A" is wrong, since the BOP operator may, at any time when not required to be performinq an immediate action or sequenced steps, throttle AFW flow if minimum heat sink requirements are satisfied. This includes isolating AFW flow to a faulted SG. The crew is currently performing an immediate action requiring action by the BOP operator. "A" is plausible since the BOP is expected to expeditiously isolate AFW to the faulted SG to minimize the cooldown. "B" is wrong, and plausible, since the BOP must receive direction from the US/SM when isolating AFW flow to a ruptured SG. "D" is wrong, but plausible, since the BOP can has to wait for 8% level prior to throttling AFW flow in two instances: if the SG has a ruptured tube, or if minimum heat sink requirements won't be met after throttling AFW. Even though the "A" MDAFW pump, which feeds two intact SGs, did not start, >530 gpm will exist since the TDAFW pump is also running.

D. RCP thermal barrier return valves 3CCP*AOV 178B or 178C will automatically close.
Proposed Answer: D Explanation (Optional):
"A" is wrong since RHR is not placed in service during the cooldown until MODE 4. The "B" RHR heat exchanger is isolated from the RCS and vented to RWST pressure. "B" is wrong since the letdown heat exchanger is on Train "A". "C" is wrong since the seal water return pressure is 30-50 psig, or less than RPCCW pressure. "D" is correct since an RCS leak into the "B" RPCCW surge tank can only come from thermal barrier for the B or C RCP or excess letdown heat exchanger. If leakage increases, the RCP thermal barrier return valves automatically close to protect the RPCCW system from overpressure. All distractors are plausible since they are components cooled by RPCCW.

C. Natural circulation can be verified. Heat removal is being maintained by atmospheric steam dumps.
D. Adequate natural circulation can NOT be verified. Heat removal may be established by throttling the atmospheric steam dump valves open.
Proposed Answer: C Explanation (Optional):
A and B are incorrect because on a loss of off site power, condenser steam dumps are unavailable due to loss of circulating water pumps.

- 2. With RCS hot leg temperature at 2550 F, the "B" train of RHR was also placed in service in the cooldown mode.
Current conditions:
"* The "B" train of RHR has just been isolated from the RCS due to a significant RHR piping leak.
"* Hot leg temperature is 210°F.
"* The "A" and "B" RCPs are running.
What concern is there with the "B" RHR train isolated?
A. The "B" train of RHR normally provides CVCS letdown.
B. The "B" train of RHR is required to provide an ECCS injection flowpath.
C. The "B" train of RHR is needed for cooldown to prevent exceeding RPCCW temperature limits.
D. The "B" train of RHR is required if COPPS is not armed.
Proposed Answer: D Explanation (Optional):
"D" is correct, since COPPs is required <226°F, from either COPPS or RHR suction relief valves, and COPPS is not armed. "A" is wrong, since letdown is aligned to the first train of RHR placed in service. "B" is wrong, since only one RHR train is required to be available for alignment to the injection mode in MODE 4. "C" is wrong, since RPCCW temperature limits can be maintained by slowing the cooldown rate on a single train of RHR. "A", "B", and "C" are plausible since RHR is involved in each of these functions.

"* All automatic equipment responds as expected
"* Containment temperature is 145 0 F
"* Containment High Range Monitors RE04A and 05A read 2R/hr

"* Core exit thermocouple temperature is 500°F
"* Pzr level is 24% and slowly increasing.
Assuming conditions do not significantly change, in which of the following procedures will the crew be directed to stop one charging pump?
A. E-0 "Reactor Trip or Safety Injection".
"B. ES-1.2, "Post-LOCA Cooldown and Depressurization".
D. E-1 "Loss of Reactor or Secondary Coolant" Proposed Answer: C Explanation (Optional):
Step 16 of E-0 will not allow stopping the charging pump. Because RCS pressure is less than 1650 psia the operator will move to the right hand column at step 16 of E-0 (i.e. conditions for stopping a CHS pump will not be evaluated). ("A" is wrong).
The operator will transition to E-1 at step 26 of E-0 due to abnormal radiation. E-1 step 6 will allow transition to ES-1.1 if four ECCS termination criteria are satisfied. Subcooling is about 100'F, and 32°F is required. Heat Sink is available (AFW auto started, and operators control feed flow based on EOP steps). RCS pressure is stable. PZR level is > 16%. Therefore a transition to ES-1.1 will be made ("D" wrong), and a charging pump will be stopped lAW Step 4 of ES-I.1
("C" is correct).
A transition from E-1 to ES-1.2 will only be made if the Operator reaches Step 13 of E-1. If the Operator properly executes E-1 he will transition out of E-1 at Step 6 ("B" wrong).

Proposed Answer: C Explanation (Optional):
"C" is correct, and "A" is wrong since the WTT requires a 175 minute recirc time. 40 minutes is the time required for the Low Level Waste Drain Tank. "B" is wrong, since while it is desirable to perform discharges during ebb tides, needs of the station may preclude this. "D" is wrong, since the normal requirement for dilution is 3 Circ Pumps, and 5 are running. "D" is plausible, since thermal backwashing reduces the number of operating circ pumps below normal.

With the plant at 100% power, the following sequence of events occurs:
- 1. The reactor trips and safety injection actuates.
- 2. Over the next 10 minutes, RCS pressure decreases to and stabilizes at 1600 psia.
- 3. The crew is responding using ECA-1.2, "LOCA Outside Containment."
- 4. While attempting to isolate the break, the final valve the crew closes in attempt to isolate the leak is RHR pump "A" cold leg injection valve (3SIL*MV8809A).
- 5. After 3SIL*MV8809A closes, RCS pressure holds steady at 1600 psia.
Which procedure will the crew transition to from ECA-1.2?
A. E-1 "Loss of Reactor or Secondary Coolant".
C. ES-1.2 "Post LOCA Cooldown and Depressurization".
D. ECA-1.1 "Loss of Emergency Coolant Recirculation".
Proposed Answer: D Explanation (Optional):
JUSTIFICATION: "D" is correct, since if the break is not isolated the crew transitions to ECA 1.1 per the step 5 RNO. It can be determined that the break is not isolated since RCS pressure does not increase ("B" wrong). "B" is plausible, since If the break is isolated, the crew transitions to E-1, and RCS pressure is steady, not decreasing.
"C" is incorrect because there is no entry into ES-1.2 from ECA-1.2. "C" is plausible since the break size is small, which ES-1.2 is designed to mitigate.
"B" is incorrect because if the leak is isolated, the crew must first go to E-1 and subsequently to ES-1.1. "B" is plausible since if the leak is isolated, this procedure will be used to terminate SI.

What is the preferred emergency bus electrical lineup?
A. Both diesels running, supplying their respective emergency buses with the tie breakers open. The non-emergency busses are supplied from offsite power.
B. Both diesels in standby, offsite power supplying both the emergency and non emergency buses.
C. Both diesels running, supplying their respective emergency buses in parallel with offsite power.
D. One diesel supplying it emergency bus, preferably the diesel with the running charging pump; the other emergency bus supplied from offsite power.
Proposed Answer: D Explanation (Optional):
Switchyard and transmission lines are not rated to withstand wind speeds in excess of 90 mph.
For this reason it is best to shutdown to HOT STANDBY and run one EDG supplying one emergency bus. Use the EDG which corresponds to the bus with the operating charging pump.
Consider using the EDG/charging pump combination on the electrical train with the most available safety equipment. RCP seal failure could occur as a result of the loss of all AC power, complicating the accident. Reducing temperature to LESS THAN 400°F prior to a loss of all AC makes seal failure unlikely.
