Incorrect. First part is incorrect (See C.1). Plausible if the applicant reversesthe system response so that the rod control system would insertrods to suppress the indicated power rise due to the failure insteadof trying to adjust actual reactor power and Tavg to match thefailed indication. Second part is incorrect (See C.2). Plausible if the applicantbelieves that during the performance of STP-33.0B, the 'B' ReactorTrip Bypass Breaker will not open since that train is being tested.B. Incorrect. First part is incorrect (See A.1). Second part is correct (See C.2).
| |
| C. Correct. First part is correct. Impulse pressure, PT-477 is used to calculateTref. Since PT-447 failed high, Tref fails to the 100% power Trefand the rod control system will step rods out in order to raise current Tavg to match Tref. Impulse pressure is also used todetermine turbine power as compared to reactor power in the rodcontrol circuitry. When PT-447 fails high, the rapid rate of change of impulse power as compared to reactor power will also causerods to step out while impulse pressure is changing. This scenario has been run on desktop simulator and the rods willstep out (IC 058). Second part is correct. FSD A18007, Figure 2 sheet 2, shows thata manual trip actuation will open the 'B' Reactor Trip BypassBreaker. D. Incorrect. First part is correct (See C.1).

First part is incorrect (See C.1). Plausible since the procedurerequires both conditions to be met before starting the RCP. Theapplicant could have the misconception that the light is associatedwith both the time and oil pressure. Second part is correct (See C.2). B. Incorrect. First part is correct (See C.1) Second part is incorrect (See C.2). Plausible if the applicant thinksthat the procedural requirement of allowing the oil lift pump to runfor at least two minutes is to satisfy a closing time delay interlock.C. Correct. First part is correct. RCP oil pressure must be a minimum of 600psig for the white light to come on. This may occur in as little as 1minute or as long as 6 minutes, but the white light is not timedependent, it is only pressure dependent. Second part is correct.

| < 325°F. If one or more of the RHR Loopsuction valves closed, then this Technical Specification would not be met and LowTemperature Over Pressure Protection would not be satisfied.Distracter analysisA. Incorrect. See B. Plausible if applicant remembers that the RHR Loopsuctions are opened and de-energized at some point but cannotrecall that it is when RCS temperature is less than 180°F. If thevalves were de-energized they would not shut so no action wouldbe required. Also, the applicant could remember that PT-402 and403 provide interlocks to OPEN the RHR loop suctions but NOTremember they also will close the valves on high pressure. Thiswould make this a correct answer. B. Correct. PT-402 failing high will close MOV-8701A and MOV-8701B whichisolates the suction to the 1A RHR pump. AOP-12 requires the 1ARHR pump to be secured. C. Incorrect. See B. Plausible if the applicant improperly believes that PT-402affects the 1B RHR pump suction valves instead of 1A RHR pump suction valves. If PT-403 failed high, this would be the correctanswer.D. Incorrect. See B. Plausible since the RHR loop suction valves have interlocks to prevent opening them if certain parameters are notmet (See reference material FSD A181002). PT-402 must be less than 402.5 psig in order to open MOV-8701A and MOV-8702Awhich are on OPPOSITE trains. If the applicant thought that theclosing on high pressure works the same way as the openinginterlocks this would be a correct answer since they would believea suction valve in each train will close and both RHR pumps wouldbe required to be secured.

| Check if LHSI Pumps should be stopped.Purpose: To stop the low-head SI pumps if RCS pressure is above their shutoff headto prevent damage to the pumpsBasis: Upon safety injection initiation all safeguard pumps are started regardless of thepossibility of high RCS pressure with respect to the low-head safety injection pumpshutoff head. On low-head systems where the pump recirculates on a small volumecircuit there is concern for pump and motor overheating. Shutdown of the pump andplacement in the standby mode, when the RCS pressure meets the criteria outlined inthis step, allows for future pump operability. If SI has not been previously reset and thelow-head SI pumps should be stopped, SI should be reset prior to stopping the pumps.SI can be reset regardless of containment pressure.FSD - A181009 3.3.1.1 3 Safety injection accumulators shall function as passive safeguardscomponents to rapidly inject [...] whenever the RCS pressure decreases below the tankcover gas pressure of 601 - 649 psig due to a loss of coolant accident Distracter AnalysisA.

| WOG Executive Guideline - During situations where a steam vent path is establishedfrom the pressurizer vapor space and where RCS subcooling is not indicated,pressurizer level may not be a true indication of RCS inventory. This can result fromsteam generated in the reactor vessel, passing through the pressurizer surge line andpreventing the water inventory of the pressurizer from draining into the RCS loops. Thisholdup of water can result in a stable or even increasing indicated pressurizer levelwhile RCS water inventory is actually decreasing. Pressurizer level should be relied ononly with hot leg or core exit subcooling present. In SI termination steps in the ERGs,pressurizer level is only checked after adequate RCS subcooling is confirmed.Distracter analysisA. Incorrect. First part is incorrect (See D.1). Plausible if applicant believes thatthe temperature of the steam in the Pressurizer is the sametemperature as the steam entering the PRT. 546°F is theapproximate saturation temperature for 1035 psia. This was theerror made at the TMI accident. Second part is correct (See D.2).B. Incorrect. First part is incorrect (See A.1). Second part is incorrect (See D.2). This is initially true but in thescenario given, subcooling is lost in the core and a bubble is formed in the vessel upper head. This will result in the Pzr level rising instead of lowering as one would expect. Plausible sinceduring a LOCA event the normal response is that Pzr leveldecreases. C. Incorrect. First part is correct. (See D.1)
| |
| Second part is incorrect (See B.2). D. Correct. First part is correct. Using the steam tables and the following pressures: 1020 psig + 15 = 1035 psia (RCS) 55 psig + 15 = 70 psia (PRT) ~320°F Second part is correct. Since the break is at the top of thepressurizer, the pressurizer level will be rising. This scenario wasrun on the desktop simulator. Pressurizer level was rising at 1020psig.

| |
| open ALL reactor trip a nd bypass breakers ONLY open the 'B' reactor trip breaker and the 'B' reactor trip bypass breaker ONLY open the 'B' reactor trip breaker and the 'A' reactor trip bypass breaker open BOTH reactor trip breakers but NOT open either reactor trip bypass breaker A.B.C.D.
| |
| FSD-A181007:3.3.2 pg 3-10The first method of tripping the breaker (i.e., reactor trip or bypass breakers) is by aloss or drop of rated voltage to the Undervoltage Relay (UV
| |
| ). The relay is normallyenergized from the 48 volt DC from the RPS.
| |
| When the voltage is removed by anautomatic reactor trip signal, the relay is de-energized and releases the UV trip lever,which actuates the trip shaft, causing the breaker to unlatch from the closed position. The second method of tripping the trip shaft is by the shunt trip lever when thenormally de-energized shunt trip (SHTR) coil is energized. When energized, the SHTRcoil is powered from the 125 volt DC system used to close the reactor trip andbypass breaker closing circuits.Distracter analysisA. Correct. Without 'A' train DC, the UV coils from the "A' Train ReactorProtection System (RPS) will still open 'A' Trip and 'B' Bypassbreakers. 'B' train RPS deenergizes the UV coils for 'B' Trip and 'A'Bypass breakers. 'B' Train Aux Building DC will open the 'B' Tripbreaker.B. Incorrect. See A. Plausible if the applicant did not recall that the UV coilsfrom RPS will trip ALL Trip and Bypass breakers. Since both listedbreakers are 'B' breakers, this adds to plausibility due to theapplicant thinking the 'B' train is unaffected and still would cause areactor trip if the system worked this way.C. Incorrect. See A. Plausible since this is how the RPS opens the Trip andBypass breakers. The applicant may recall that this is how the RPS works but not realize that the loss of 'A' Train DC has no effect onthe RPS. D. Incorrect. See A. Plausible if the applicant thinks that the Trip breakers aretripped by RPS and the Bypass breakers from Aux Building DC.Since the Shunt trip coils on the Bypass breakers can ONLY beoperated locally, the applicant may think that without DC theBypass breakers will not open.

| |
| : 2) DRPI A.B.C.D.The Bank Demand Position Indication System counts the pulses from the Rod ControlSystem that move the rods. There is one step counter for each group of rods. Individualrods in a group all receive the same signal to move and should, therefore, all be at thesame position indicated by the group step counter for that group. The Bank DemandPosition Indication System is considered highly precise (+/- 1 step or +/- ? inch).
| |
| If a roddoes not move one step for each demand pulse, the step counter will still countthe pulse and incorrectly reflect the position of the rod. The DRPI System provides a highly accurate indication of actual control rod position, but at a lower precision than the step counters. This system is based oninductive analog signals from a series of coils spaced along a hollow tube with a centerto center distance of 3.75 inches, which is 6 steps. To increase the reliability of thesystem, the inductive coils are connected alternately to data system A or B. Thus, ifone system fails, the DRPI will go on half accuracy with an effective coil spacing of 7.5inches, which is 12 steps. Therefore, the normal indication accuracy of the DRPI System is +/- 4 steps (all coils operable and 1 step added for manufacturing andtemperature tolerances), and the maximum uncertainty is +/- 10 steps (only one datasystem A or B coils operable). With an indicated deviation of 12 steps between thegroup step counter and DRPI, the maximum deviation between actual rod position andthe demand position could be 22 steps.
| |
| Distracter analysisA. Incorrect. First part is incorrect (See D.1). Plausible if the applicant does notrecall that the Step Demand Counter only counts electricalimpulses and thinks it actually measures rod location. Second part incorrect (See D.2). Plausible if the applicant thinks that since the group step counters are the most precise indication,they are the most reliable. B. Incorrect. First part is incorrect (See D.1). Plausible if the applicant does notrecall that the Step Demand Counter only counts electricalimpulses. Each bank has 2 Step Demand Counters that step in 1step increments. Control Bank D Group 1 will move 1 step then Control Bank D Group 2 will move one step. If bank 1 moves 1 step and the rod control switch is released before bank 2 moves,bank 1 would be at 100 steps and bank 2 would be at 99 steps.This is commonly known as 991/2 steps. The applicant mayreason that this is a potential reason to call rods by step counter asapproximate. Second part is incorrect (See A.2).
| |
| C. Incorrect First part is incorrect (See D.1). Plausible since the DRPI lightschange only every 6 steps and 54 steps is a DRPI display lightlocation. The applicant may think that since a DRPI display light islit, the rod is exactly at that position. Second part is correct (See D.2).
| |
| D. Correct. First part is correct. Since DRPI measures actual rod positionbased on the location of the rod in reference to the measurementcoils and the step counter only counts electrical pulses, the rod is at ~54 steps. Also, the accuracy of DRPI is
| |
| + 4 steps so the rodheight is approximate. Second part is correct. DRPI is the most reliable because itactually senses the location of the rod using coils.

However, there is no data to determine at what point the mass of Containmentatmosphere increases to the point where the Slow speed fan would draw morecurrent than Fast speed. With the Containment Cooler in Slow at the beginningof the event, the applicant will only have to evaluate the current drawn by thecooler based on atmospheric conditions (humidity) which meets the K/A -Containment Cooling System (CCS) - Ability to predict and/or monitor changes in parameters (to prevent exceeding design limits) associated with operating theCCS controls including: Containment humidity.
| |
| Tech Spec 3.6.6 Bases:In post accident operation following an actuation signal, unless an LOSP signal ispresent, the Containment Cooling System fans are designed to start automatically inslow speed if not already running. If an LOSP signal is present, only the two fansselected (one per train) will receive an auto-start signal and will start in slow speed. Ifrunning in high (normal) speed, the fans automatically shift to slow speed.
| |
| The fans are operated at the lower speed during accident conditions to prevent motoroverload from the higher mass atmosphere. In addition, if temperature at thecooler discharge reaches 135°F, fusible links holding dropout plates will open and the fan discharge will no longer be directed through the common dischargeheader. This function helps to protect the fans in a post-accident environment byreducing the back pressure on the fans.FSD- A181013

First part is correct. (See A.1) Second part is incorrect (See A.2). Plausible if the applicant thinksthat reduced charging flow would equate to reduced mini-flow flow which is incorrect. Also, the charging miniflow goes through theseal water return HX and temperature would be unaffected bychanging charging flows. C. Incorrect. First part is incorrect (See A.1). Plausible since Figure 1 ofSOP-2.1, re-establishing LTDN after isolation with no equipment malfunction, has the operator establish 40 gpm flow rate in step 1 when placing one orifice on service.

| |
| There has been a loss of CVCS flow due to a controllerfailure. FK-122 has been placed in manual and is now beingplaced in AUTO.
| |
| A reason for placing FK-122 in AUTOand not leaving it in MANUAL is to ensure adequate cooling to the regenerative heat exchanger to preventflashing downstream of the letdown orifices with one 60gpm orifice on service should the controller fail to minimum demand based on current plant conditions.The operational implication would be that flashingwould occur if Chg flow were to fall to <18 gpm and
| |
| | |
| cause damage to the orifices and piping due to waterhammer and the flashing of water to steam. A loss ofletdown would be the result. This question meets the KAin that it asks the minimum flow rate for being in auto if acontroller were to fail and the reason.SRO justification: N/A

Plausible because the applicantcould confuse the SFP minimum boron concentration with theaccumulators minimum boron concentration which is 2200 ppm.C. Correct. First part is correct. FT-168 will regulate total makeup flow to 120gpm. This is a combination of acid flow and Reactor MakeupWater (RMW) flow. The amount of acid flow will be determined by the properly functioning FT-113. This means that the malfunctioning LOWER signal sent to FK-168 by FT-168 will cause the system to raise the flow of RMW to achieve a "sensed" totalflow of 120 gpm resulting in more RMW than expected therefore alower boron concentration in the makeup water supplied to theSFP.

Plausible since the applicant maydetermine subcooling based on ruptured SG pressure vs. RCSpressure. This would be a common misconception since in aSGTR procedure the ruptured SG is the focus for determining SGpressure less than RCS pressure and is the pressure referred towhen determining the required CETC temperature to cooldown to. 948 psig + 15 = 963 psia which is 540°F 540°F - 518°F = 22°F subcooling.

Subcooling is greater than16°F, however, RCS pressure is less than the affected SGpressure and pzr level is >15%.Therefore the pressure reduction isrequired to be stopped. Plausible since the subcooling is met andthe Pzr level is <63%, so one more evaluation as to be done. Thisevaluation has two components and one of the two components ismet. Also if the candidate were to compare RCS pressure vs oneof the other two SG pressure, then the pressure reduction would be continued.C. Correct. First part is correct. 916 psig + 15 = 931 psia which is ~536°F 536°F - 518°F = 18°F subcooling.Second part is correct. AOP-2.0 has the operator evaluate 3components, two of which do not require the RCS pressurereduction to be stopped. However, RCS pressure is less thanaffected SG pressure, (RCS pressure is 916 psig and SG pressureis 948 psig) AND pressurizer level greater than 15% (at 43%).D. Incorrect.

| Initially, as the feed pump turbine accelerates from operation on the turning gear tooperating speed, both the LP and HP stop valves are open. The first governor valve toopen on an increase speed signal from the control system is the LP governor. Sincereheat steam is not available, the turbine speed does not in crease. Once the LPgovernor valves begin to reach their fully open position, the HP governor valve begins to open. The turbine now accelerates to the demanded speed using the main steamsupply via the HP governor valve. As main turbine load is increased, reheat steam pressure in the shell side of the MSRsalso increases. At approximately 25 percent main turbine power, the reheat steampressure is high enough to cause the feed pump turbine speed to increase. In an effortto maintain the desired feed pump turbine speed, the control system begins to shut theHP governor valve. Once the HP governor valve approaches the fully shut position, thecontrol system starts closing the LP governor valves. During 100 percent poweroperation, the governor valve alignment is as follows: 1. The HP governor valve is fully shut. 2. The LP governor valve is throttled partially shut and consequently controls feedpump turbine speed.* Some validators selected the correct answer but stated that they struggled withdetermining the response of governor valves when the SGFP tripped.Distracter analysis A. Correct. First part is correct. The Servo controller shuts the HP governorvalve when the SGFP turbine trips. Second part is correct. The Servo controller shuts the LP governorvalve when the SGFP turbine trips.B. Incorrect. First part is correct (See A.1).

R-23B isafter the surge tank and is the last rad monitor and isolation signal before an accidentalrelease would make it to the environment. R-23 A and B are often confused on thefunctions and locations. Two other sets of valves isolate SGBD due to otherconditions, such as High Penetration room pressure and AFW autostart. All of thesevalves complete the same function but for different reasons.Distracter analysisA. Incorrect. See B. Plausible since these valves will isolate SG Blowdown(SGBD) and automatically close on an AFW autostart. Theapplicant could believe they also close on a high radiation signal.B. Correct. R-23A automatically closes FCV-1152. FCV-1152 also closes onSGBD high ST level, High pressure in the SGBD system and High flow.C. Incorrect. See B.

RCV-023B will isolate SGBD to the environment and isdownstream of FCV-1152.D. Incorrect. See B.

Since the 1A SUT powers the 1A bus andthe 1B SUT powers the 1B and 1C busses, only the 1A bus is lost. The opposite is trueon Unit 2 so the applicant has to recall how each unit is configured.Secondly, the applicant has to recall how the loss of power affects the MDAFW pumps.The 1B MDAFWP is unaffected since the 1G bus did not lose power as it is poweredfrom 1B SUT. The 1A MDAFW pump did lose power and will be sequenced on the buswhen the DG starts and the LOSP sequencer runs.Thirdly, once the applicant determines which AFW pumps are running, then they willhave to recall design flow rates for each (350 gpm for the MDAFW and 700 gpm for theTDAFW pump) to determine total approximate flow. Distracter analysisA. Correct. First part is correct. FSD-A181010 - 3.9.2.3 - The TDAFW pumpshall start by opening the steam supply valves to the turbine driveon a loss of power signal, low-low water level signals from twoout of three level transmitters of any two out of three steamgenerators, or an AMSAC signal. The loss of power signal comesfrom the loss of power to 2 of 3 RCP busses (1A, 1B and 1C).Since ONLY the 1A bus loses power, the TDAFW pump does not start.) Second part is correct.

Correct First part is correct. When the pond level drops to 180 ft 0 in, theSW the SW system changes valve alignments such that theemergency recircs to the pond open and the discharges from eachtrain closes which lowers the dilution flow as seen on FR-4107.
| |
| Second part is correct. The dilution line flow drops to less than14,500 gpm (goes to 0 gpm), which in turn causes the auto-closureof RCV-023B, terminating this Release path. See D200013 for line up.B. Incorrect. First part is correct (See A.1) Second part is incorrect (See A.2). RCV-018 does not have a lowdilution line auto closure. Plausible since RCV-023B is also aradioactive release point isolation and will close on both HighRadiation and Low Flow so the app licant could think it also closedon low flow.C. Incorrect. First part is incorrect (See A.1). SW discharge pressure is virtuallyunchanged due to the lineup. When run on desk top simulator,pressure ROSE ~1.5 psig. Plausible since the SW header willoperate on RECIRC back to the POND, the applicant may believe this would cause a lowered backpressure on SW header whichwould translate into a higher flow but at a lower pressure(Centrifugal pump curves). Second part is incorrect (See A.2). Since SW discharge pressure isvirtually unaffected then these valves will NOT fully open becausedischarge pressure is less than 110 psig. Plausible if the applicantbelieves that the system "DILUTION BYPASS" valves open toensure a minimum dilution flow is maintained for Radioactivereleases. .

| |
| Check Ruptured SG(s) LevelPurpose: 1. To reduce feed flow to the ruptured steam generators to minimize thepotential for steam generator overfill.
| |
| : 2. To establish and maintain a water level in the ruptured steam generators abovethe top of the U-tubes in order to promote thermal stratification to preventruptured steam generator depressurization.Basis: It is also important to maintain the water level in the ruptured steam generator abovethe top of the U-tubes. When the primary system is cooled in subsequent steps, thesteam generator tubes in the ruptured steam generator will approach the temperatureof the reactor coolant, particularly if reactor coolant pumps continue to run. If the steamspace in the ruptured steam generator expands to contact these colder tubes, condensation will occur which would decrease the ruptured steam generator pressure.
| |
| As previously demonstrated (see Step 3), this would reduce the reactor coolantsubcooling margin and/or increase primary-to secondary leakage, possibly delaying SItermination or causing SI reinitiation. Consequently, the water level must be maintainedabove the top of th e tubes to insulate the steam space.
| |
| In addition to insulating thesteam space, this ensures a secondary side heat sink in the event that no intactsteam generator is available and also provides protection against misdiagnosis of theruptured steam generator due to an imbalance of feed flow.Distracter analysisA.

| |
| This procedure provides actions to restore emergency coolant recirculationcapability, to delay depletion of the RWST by adding makeup and reducing outflow,and to depressurize the RCS to minimize break flow.Distracter AnalysisA. Incorrect. First part is incorrect (See C.1). Plausible if the applicant doesn'trecognize that the DG trip results in the loss of the 1A RHR pump.
| |
| Second part is incorrect (See C.2). Plausible if the applicant thinksthat one train of recirc capability is available because this would be partially correct. The containment spray is not transferred to sumprecirc until the RWST is less than 4.5 ft. The applicant could beunfamiliar with the procedure and believe that both cold leg and containment spray are required to be transferred to sump recircwhen RWST is at 12.5 ft.B. Incorrect. First part is incorrect (See A.1) Second part is incorrect (See C.2). Plausible since this would bethe correct answer if recirc capability existed.C. Correct. First part is correct. Since neither RHR pumps are available so there is no recirculation capability. Second part is correct. This is the correct strategy for ECP-1.1.D. Incorrect. First part is correct (See C.1).
| |
| Second part is correct (See C.2). Plausible if the applicantrecognizes that recirculation capability is lost but incorrectlybelieves that CH2 and CH3 being in alarm indicates that theRWST is less than 4.5 ft which would make this the correct answerper step 34 of ECP-1.1.

| |
| ECP-2.1Step 4: [CA] Maintain at least 20 gpm AFW flow to SGs with narrow range level less than 31%{48%}.ECB-2.1Basis: If feed flow to a SG is isolated and the SG is allowed to dry out, subsequentreinitiation of feed flow to the SG could create significant thermal stress conditions onSG components. Maintaining a minimum verifiable feed flow to the SG allows thecomponents to remain in a "wet" condition, thereby minimizing any thermal shock effects if feed flow is increased.Distracter AnalysisA. Incorrect. See B. Plausible because stopping AFW flow would deplete thewater inventory and stop the cooldown. This is the strategy ofEEP-2.0, to stop all feed flow to the SG and allow it to blow down.This is not allowed by this procedure and would result in a loss ofheat sink.B. Correct. Per ECP-2.1, the operator is required to maintain at least 20 gpmAFW flow to SGs with narrow range level less than 31%{48%} to prevent dryout of the SGs. C. Incorrect. See B. Plausible if the applicant confuses AFW to EACH versusTotal AFW flow. If this were 20 gpm to EACH SG it would be acorrect answer.D. Incorrect. See B. Plausible since this meets the Heat Sink Critical SafetyFunction Status Tree. FRP-H.1, Response to Loss of SecondaryHeat Sink, has a caution that says the following: This procedureshould not be performed if total AFW flow is less than 395 gpmdue to operator action.

| Step 1 Basis: This step instructs the operator to try to identify the unexpected source ofthe water in the containment sump. Containment flooding is a concern since criticalplant components necessary for plant recovery may be damaged and renderedinoperable.Distracter analysisA. Correct. Step 1 of FRP-Z.2 directs evaluating potential sources of flooding.The background document states - This step instructs the operator to try to identify the unexpected source of the water in thecontainment sump. Containment flooding is a concern since critical plant components necessary for plant recovery may be damagedand rendered inoperable.B. Incorrect. See A. Plausible since the ECCS system does enter containmentand the applicant may improperly think that this is a source offlooding. If the ECCS system were damaged, then determining astrategy for going on to simultaneous cold and hot leg recirculationwould be a plausible reason for this step. There is no step toevaluate ECCS as a source of flooding as it is designed to put water into the recirculation sump via the RCS break.C. Incorrect. See A. Plausible since this is Step 2 and the basis for this step inFRP-Z.2. The applicant may not be familiar with the procedure andbelieve that this is the first step.D. Incorrect. See A. Plausible since Step 3 does have the TSC evaluate sumpchemistry, and activity level but not for this reason.
