A plant load increase at %% per minute is in progress.
A malfunction in the Rod Control System results in Control Rods stepping out TEN (10) steps, at which point they are placed in MANUAL and stop moving.
The load increase is stopped 2 minutes after the failure.
Control Rods are manually inserted to restore Tavg to Tref.
Considering ONLY the conditions stated, which ONE (1) of the following describes how Total Power Defect has been affected, AND how far Control Rods have been inserted to restore Tavg to Tref?
A. Remained the same; less than 1 0 steps B. Remained the same; 10 steps C~ Increased; less than 10 steps D. Increased; 10 steps Feedback A.
Plausible 1 st part because on an uncontrolled rod motion malfunction, negating all other effects (including the 1 % turbine load increase), if Tavg is restored to match Tref, the total power defect remains unchanged since no net power change occurred.
Plausible because 2nd part is correct. Since the turbine load change is allowed to continue to increase for two minutes this will result in a net power change of a 1 %
power increase when Tavg is restored to Tref, Since no dilution has occurred and Tref has increased due to the change in turbine power rod height will have to be higher for Tavg to match Tref on the power increase. Rods would not have to be inserted the full 10 steps that they step out in order to match Tavg with Tref (to compensate for the positive reactivity of the 10 step withdrawal and because power defect added some negative reactivity).
Incorrect because power has increased by 1 %, therefore, Total Power Defect has increased adding negative reactivity. (Ref VCSNS curve book Figure 11-2). Since Tref as increased as a result of the turbine load increase, Tavg would have to be increased to match Tref. From the conditions stated, rod height will have to be higer to offset the negative reactivity inserted by the increase in Power Defect. Therefore, when the rods are manually inserted to match Tavg and Tref following the outward rod motion, the Wednesday, November 19, 200812:48:16 PM 3

Feedback A.
Plausible because 196°F is above the lower motor bearing trip criteria.
Incorrect because the lower seal water bearing trip setpolnt is 225°F..
B.
Plausible because, if MVG-9600 were to close, CCW to the Rep thermal barriers would be lost, which could eventually require Reps to be shutdown.
Incorrect because, even if all CCW were lost to the Reps, the crew would still have 10 minutes to restore prior to securing the Reps.
C.
Plausible because ARP-001-XCP-617, 1-4, Corrective Action 3, requires monitoring T0413A, RCPA MTR UPPER RAD BRG T-TE418A.
Incorrect since the given temperature is below the setpoint of 195°F for securing the RCP..
D.
CORRECT. lAW ARP-001-XCP-617, 1-3, Supplemental Action 2, if frame vibration is greater than 5 mils, the Rep should be secured if power is less than 38%.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
- 5. 004 A3.15 0011NEW//LOWERlIRO/SUMMERl2/2009INO Given the following plant conditions:
Mode 5 The RCS is solid with pressure being automatically maintained.
A licensed operator trainee inadvertently energized one set of PZR Backup Heaters.
Assuming NO operator action, which ONE (1) of the following describes the FIRST response to the rising RCS pressure?
A. The Letdown Line Relief Valve opens.
B. The RHR Suction Relief Valve(s) opens.
C. Annunciator LP LTDN FLO/PRESS HI actuates.
D~ Flow increases through PCV-145, Letdown Pressure Control Valve.
Feedback A.
Plausible because it is.in the flow stream and may occur if PCV-145 were full open due to the rising pressure.
Incorrect because it would not open before the RHR Suction Reliefs (450 psig).
B.
Plausible because they are in the flow stream and may lift if PCV-145 and the RHR Suction Reliefs were unable to terminate the rising pressure.
Incorrect because they would not open until 450 psig and PCV-145 will sense pressure increasing as pressure exceeds its normal setpoint of 350-400 psig.
C.
Plausible because this would eventually occur at 400 psig if PCV-145 did not initially control the rising pressure.
Incorrect because, in this case, no adjustments to charging and letdown have bfilen made and PCV-145 would act first and automatically maintain pressure until it is 100%
open.
D.
CORRECT. PCV-145 controls RCS pressure with the system solid. With the term "automatically" specified in Bullet 2, PCV-145 is set at 350 PSIG. As such, It will respond before the letdown relief (600 psig) and the RHR suction reliefs (450 psig).
Until PCV-145 is 100% open, system pressure will be maintained.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
Plausible because PRT pressure could stabilize at a high pressure without rupturing the PRT rupture disc if the PORVs could be closed in a timely manner. Also plausible because the second half is the correct procedural flowpath.
B Plausible because PRT pressure could stabilize at a high pressure without rupturing the PRT rupture disc if the PORVs could be closed in a timely manner. Procedural flowpath is plausible because given information matches Entry Conditions into AOP-214.2; however, at 55% Oust above P-9 setpoint of 50%), an immediate Reactor Trip will result from a Turbine Trip, which resulted from the generator field failure. See drawing E-203-201. (Field Failure (40)/Generator Backup Lockout (86GC)/Generator Electrical FaultlEHC System External Trips/Mechanical Trip Relay/Mechanical Trip Solenoids/Mechanical Trip Valve (Turbine Trip).
C.
CORRECT. The PRT rupture disc will fail shortly after a" PORVs open, then PRT pressure will drop and equalize with RB pressure.
For this event, RB pressure will be less than the normal PRT pressure. The Field Failure will result in a Turbine Trip (see drawing E-203-201) and, at 55%, this will cause a Reactor Trip, so EOP-1.0 wi" be implemented. When the CRS reaches the diagnostic steps, RB sump levels will NOT be normal and this warrants a transition to EOP-2.0.
D.
Plausible because the 1 st part is correct - the PRT rupture disc will fail shortly after a" PORVs open, then PRT pressure will drop and equalize with RB pressure..
Procedural flowpath is plausible because given information matches Entry Conditions into AOP-214.2; however, at 55% Oust above P-9 setpoint of 50%), an immediate Reactor Trip will result from a TurbineTrip.

QUESTIONS REPORT ferVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
Plausible because PRT pressure could stabilize at a high pressure without rupturing the PRT rupture disc if the PORVs could be closed in a timely manner. Also plausible because the second half is the correct procedural flowpath.
B Plausible because PRT pressure could stabilize at a high pressure without rupturing the PRT rupture disc if the PORVs could be closed in a timely manner. Procedural f10wpath is plausible because given information matches Entry Conditions into AOP-214.2; however, at 55% Gust above P-9 setpoint of 50%), an immediate Reactor Trip will result from a Turbine Trip, which resulted from the generator field failure. See drawing E-203-201. (Field Failure (40)/Generator Backup Lockout (86GC)/Generater Electrical FaultlEHC System External Trips/Mechanical Trip Relay/Mechanical Trip Solenoids/Mechanical Trip Valve (Turbine Trip).
C.
CORRECT. The PRT rupture disc will fail shortly after all PORVs open, then PRT pressure will drop and equalize with RB pressure.
For this event, RB pressure will be less than the normal PRT pressure. The Field Failure will result in a Turbine Trip (see drawing E*203-201) and, at 55%, this will cause a Reactor Trip, so EOP-1.0 will be implemented. When the eRS reaches the diagnostic steps, RB sump levels will NOT be normal and this warrants a transition to EOP-2.0.
D.
Plausible because the 1 st part is correct - the PRT rupture disc will fail shortly after all PORVs open, then PRT pressure will drop and equalize with RB pressure..
Procedural flowpath is plausible because given information matches Entry Conditions into AOP-214.2; however, at 55% (just above P-9 setpoint of 50%.), an immediate Reactor Trip will result from a TurbineTrip.

Feedback A.
Plausible because most of the given symptoms are consistent with a MSLB. Also plausible because the 2nd part is correct for a PZR steam space break.
Incorrect because RM-A2 would not be increasing for a MSLB.
B Plausible because most of the given symptoms are consistent with a MSLB.
2nd part is plausible because, for some steam line breaks, Tavg will decrease, pressurizer level setpoint will decrease, and charging flow ill decrese to restore PZR level to program level.
C.
CORRECT. The given symptoms of RB pressure and humidity, RBCU drain flow high, tailpipe temperatures, and RM-A2 conditions are consistent with a PZR steam space break. As inventory is lost to the leak, PZR level will initially decrease and charging flow will increase when level drops below program.
D.
Plausible because the 1 st part is correct. 2nd part is plausible because, for steam space accidents, pressurizer level will eventually go off scale high and normal charging flow would decrease to zero. According to the WOG ES-1.2 Background Document (HES12BG.doc, HP-Rev. 2,4/30105, p41, Figure 13), the reference plant analysis for this event shows that the PZR level is at 100% within approximately 10 minutes.

Plausible because the first part is correct. At Step 27 of EOP-2.0 the operator is directed to GO TO EOP-2.3 within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after event initiation. Incorrect since the limiting event is a Cold Leg Break, NOT a Hot Leg Break. According to WOG ES-1.4 Background Document, during the Hot Leg break CLR will be injected into the cold Legs and forward flush the core into, and out of, the Hot Legs alleviating the Boron buildup problem.

Feedback A.
CORRECT. TS Table 3.3-1 requires the trip function to be OPERABLE in in MODE 1.
Since plant is at 3% (MODE 2), the high level trip function is NOT required. Since AOP-401.6 requires the failed channel bistables to be tripped, only one of the two remaining channels (L T -460, 461) are required to initiate a trip.
B.
Plausible because the high level trip must be OPERABLE at power, but only in MODE
- 1. Also plausible because the second part is correct. However, the channel is only required in Mode 1. It is automatically bypassed in the low power condition (P-7).
C.
Plausible because the first part is correct because TS Table 3.3-1 requires the trip function to be OPERABLE in in MODE 1. Also plausible because the logic would be correct if the failed channel were bypassed per Action 6.b of T.S. Table 3.3-1, rather than tripped per the AOP. The second part is incorrect in that the AOP-401.6 requires the failed channel bistables to be tripped; therefore, only one of the two remaining channels (LT-460, 461) are required to initiate a trip.
D.

Given the following plant conditions:
(
Mode 3 The plant is being cooled down to Cold Shutdown per GOP-6, Plant Shutdown from Hot Standby to Cold Shutdown (Mode 3 to Mode 5).
The NROATC begins depressurizing the RCS to 900-950 psig.
At 1970 psig, the NROATC takes both PZR SI Train 'A', and Train 'B', Switches to BLOCK.
PT-457, PRESSURIZER PRESSURE TRANSMITIER, fails HIGH.
Which ONE (1) of the following identifies the impact of this failure?
A. The automatic opening of the PZR PORVs is reset.
B. The Pressurizer Pressure Safety Injection block is automatically reset.
C. The automatic opening of the PZR PORVs is unaffected, provided both of the two remaining channels exceed 1985 psig.
D~ The Pressurizer Pressure Safety Injection block is unaffected, provided both of the two remaining channels remain below 1985 psig.
Feedback A.
Plausible because CAUTION 3.4.d of GOP-6 warns the operator that P-11 blocks the auto-opening of the PORVs and the failure of PT -457 HIGH would cause 1 channel to reset.
Incorrect because it takes 2/3 channels above 1985 psig to reset the block of the auto open signal to the PORVs.
B.
Plausible because CAUTION 3.4.d of GOP-6 warns the operator that the SI blocks reset above 1985 psig and the failure of PT -457 HIGH would cause 1 channel to reset.
Incorrect because it takes 2/3 channels above 1985 psig to reset the block of the PZR Pressure SI.
C.
Plausible because the 1 st part would be true if 1 of the remaining channels were to rise above 1985 psig.
D.
Incorrect because only 1 of the remaining channels rising above 1985 psig would remove the block of the auto-opening of the PZR PORVs.
CORRECT. 2 of 3 channels (PT-455, PT -456, & PT -457) below 1985 psig will allow manual blocking of the PZR Pressure SI. If PT-457 failed HIGH, the two remaining channels will still be below 1985 psig and the SI block is unaffected. (see Figure IC9.21, Sheet 2 of 2)

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
CORRECT. According to AB-4 (p46, Rev 12), a low #1 Seal Leakoff flow can be caused by improper operation of the #1 seal (Le. it is cocked pinching off actual flow through the seal), or the #2 seal. In the case of the #2 Seal, the Seal is NOT seated properly robbing flow from the #1 Seal Leakoff line. Also according to AB-4 (p40-41), insufficient flow through the #1 seal can result in insufficient cooling and lubrication of the lower RCP Radial Bearing causing an increase in bearing water temperature and Sealwater outlet temperature. Since temperatures are increasing in the stated conditions, the cocking, or pinching off of flow, is indicated through the #1 Seal. AOP-101.2, Reactor Coolant Pump Seal Failure, (Rev 0) has the operator check for abnormal temperatures early in the mitigation process of an RCP Seal Failure event. Step 4 of the AOP evaluates the bearing water temperature and Sealwater outlet temperature to ensure that they are less than required limits (225°F and 235°F respectively), AND not significantly increasing. In both situations, the limits are NOT exceeded; however, temperatures are increasing at at least 2°F/minute. Because of this, the operator will be directed to trip the Reactor and stop the affected pump (Steps 6-8).
B.
Plausible because the 1st part is correct. Also plausible because Step 6 of AOP-101.2 allows use of GOP-4C to place the plant in HOT STANDBY and because the Alternative Action for Step 6 requires load at less than 38% (P-8).
Incorrect since given condition of 100% requires a Reactor Trip.
C.
Plausible because, with an unseated #2 seal, low leakoff flow would be indicated from the #1 seal. Also plausible since #2 seal failure is listed as a Probable Cause for RCP A(B,C) #1 SL LKOFF FLO HIILO alarms. Also plausible because the 2nd part is correct for the given conditions.
Incorrect because the increase in water temperatures would not occur with an unseated
- 2 Seal. Flow would be normal through the radial bearing, providing normal cooling to the bearing.
D.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
CORRECT. According to AB-4 (p46, Rev 12), a low #1 Seal Leakoff flow can be caused by improper operation of the #1 seal (i.e. it is cocked pinching off actual flow through the seal), or the #2 seal. In the case of the #2 Seal, the Seal is NOT seated properly robbing flow from the #1 Seal Leakoff line. Also according to AB-4 (p40-41), insufficient flow through the #1 seal can result in insufficient cooling and lubrication of the lower Rep Radial Bearing causing an increase in bearing water temperature and Sealwater outlet temperature. Since temperatures are increasing in the stated conditions, the cocking, or pinching off of flow, is indicated through the #1 Seal. AOP-101.2, Reactor Coolant Pump Seal Failure, (Rev 0) has the operator check for abnormal temperatures early in the mitigation process of an RCP Seal Failure event. Step 4 of the AOP evaluates the bearing water temperature and Sealwater outlet temperature to ensure that they are less than required limits (225°F and 235°F respectively), AND not significantly increasing.

Feedback A.
Plausible because PT -446 does provide an input to High Steam Flow Coincident with LO-LO Tavg MS line isolation signal and also provides 1 of 2 inputs to P-13. Incorrect because these are protection and permissives circuits which are electrically isolated from the control signal provided by PT-446 to the Rod Control Reactor Control Unit, and therefore could not be affected by an electrical fault in this circuit.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
Plausible because, If the shaft were to shear, the indications would be similar to those described here for the Charging Pump. Incorrect because the VCT level indicators would not be at 100%, but, at this time, would be cycling between 70-80% as LCV-115A modulates.
B.
Plausible because if the pump suction were isolated (such as in a hot short on LCV-115C), the indications would be similar to those described here for the Charging Pump. Incorrect because the VCT level indicators would not be at 100%, but, at this time, would be cycling between 70-80% as LCV-115A modulates.
C.
CORRECT. According to AB3 (p28-31, Rev 13), if VCT level transmitter L T-115 fails high, a complete diversion of letdown flow occurs since this transmitter provides a backup signal to Letdown Divert Valve LCV-115A to divert to the Recycle Holdup Tank on high level in the VCT (80%). This channel also controls the start and stop signal for auto makeup which is lost now that level is failed high. In this situation, the VCT is no longer receiving letdown flow, but the Charging Pump is still removing water causing VCT level to decrease. When VCT level drops to 5%, RWST supply valves to the Charging Pump should open, and the VCT outlet valves should close, however, this automatic protection function requires signals from both the VCT level transmitters (LT-112 and L T-115), and LT-115 is failed high. With no operator action, the Charging Pump will drain the VCT and become gas bound, losing NPSH. According to AB3 (p30), the two transmitters share a common reference leg and sensing line, and are susceptible to a common mode failure. For instance, if both level transmitters were to fail high, as the conditions stated indicate, the loss of NPSH to the Charging Pump would occur as described above, and it would be masked by the simultaneous failure of LT-112. The VCT would appear full, when in actuality it has emptied, leading to a loss of Charging due to the gas binding of the pumps.
D.
Plausible because, if one phase were to lose voltage, the indications would be similar to those described here for the Charging Pump, except that amps/flow would be low, although not at minimum/zero. Incorrect because the VCT level indicators would not be at 100%, but would be cycling between 70-80% as LCV-115A modulates.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
Plausible because, If the shaft were to shear, the indications would be similar to those described here for the Charging Pump. Incorrect because the VCT level indicators would not be at 100%, but, at this time, would be cycling between 70-80% as LCV-115A modulates.
B.
Plausible because if the pump suction were isolated (such as in a hot short on LCV-115C), the indications would be similar to those described here for the Charging Pump. Incorrect because the VCT level indicators would not be at 100%, but, at this time, would be cycling between 70-80% as LCV-115A modulates.
C.
CORRECT. According to AB3 (p28-31, Rev 13), if VCT level transmitter LT-115 fails high, a complete diversion of letdown flow occurs since this transmitter provides a backup signal to Letdown Divert Valve LCV-115A to divert to the Recycle Holdup Tank on high level in the VCT (80%). This channel also controls the start and stop signal for auto makeup which is lost now that level is failed high. In this situation, the VCT is no longer receiving letdown flow, but the Charging Pump is still removing water causing VCT level to decrease. When VCT level drops to 5%, RWST supply valves to the Charging Pump should open, and the VCT outlet valves should close, however, this automatic protection function requires signals from both the VCT level transmitters (L T-112 and L T-115), and L T-115 is failed high. With no operator action, the Charging Pump will drain the VCT and become gas bound, losing NPSH. According to AB3 (p30), the two transmitters share a common reference leg and sensing line, and are susceptible to a common mode failure. For instance, if both level transmitters were to fail high, as the conditions stated indicate, the loss of NPSH to the Charging Pump would occur as described above, and it would be masked by the simultaneous failure of LT-112. The VCT would appear full, when in actuality it has emptied, leading to a loss of Charging due to the gas binding of the pumps.
D.
Plausible because, if one phase were to lose voltage, the indications would be similar to those described here for the Charging Pump, except that amps/flow would be low, although not at minimum/zero. Incorrect because the VCT level indicators would not be at 100%, but would be cycling between 70-80% as LCV-115A modulates.

Feedback A.
Plausible because, at the GOP-4C unloading rate of 5%/minute, the plant will be off-line within the 20 minute limit established in AOP-118.1 CAUTION before the Charging Pump limits are exceeded.
Incorrect because alternate cooling should still be established because the Charging Pump will be needed even after the plant is shutdown in order to supply RCP seal water.
B.
Plausible because this is one of the methods of alternate cooling allowed in AOP-118. 1,
Step 4, Alternative Action.
Incorrect because, according to Alternative Action Step 4c, Demin Water is used ONLY if Chilled water is NOT available.
C.
Plausible because this is one of the methods of alternate cooling allowed in AOP-118.1, Step 4, Alternative Action.
Incorrect because, according to Alternative Action Step 4c, Fire Service is used ONLY if Chilled Water and Demin Water are NOT available.
D.
CORRECT. According to AOP-118.1 (Rev 2), CAUTION (& CAUTION - Step 3) 1, a charging pump can continue to run on a loss of CCW to its oil coolers for 20 minutes following the event initiation, or as long as local temperature monitoring is established and no limits identified on Page 4 of 4, on Attachment 1 are exceeded. The same Caution appears prior to Step 3. The limits established by Attachment 1 are 145°F for the Gearbox Lube Oil Temperature, 150°F for the Oil Cooler Outlet Temperature, and 180°F for the Thrust Bearing Temperature. None of these limits are presently exceeded and the earliest time that a limit is expected to be exceeded is 15 minutes (Oil Cooler Outlet Temperature at 150°F). With this in mind the crew will arrive at Step 3 of AOP-118.1 and move to the Alternative Action, initiate monitoring of Charging Pump temperatures, verify that Charging Pump 'A' can continue to run without CCW and proceed to Step 4. At Step 4 they will also implement the Alternative Action when it is determined that CCW cannot be restored. This will require the operator to place Charging Pumps 'B' and 'c' in PTL, isolate letdown, and initiate alternate cooling. A" actions that are required by the procedure up to the initiation of alternate cooling have been completed as identified in the conditions of the question. The question is: "does alternate cooling need to be established, and if so, how?" While it is true that the plant will be off-line within 10 minutes at the GOP-4C unloading rate of 5%/minute, before the Charging Pump limits are exceeded, this has no bearing on whether or not alternate cooling should be established because the Charging Pump will be needed to continue running even after the plant is shutdown in order to supply RCP Sealwater. With this in mind, Alternative Cooling must be established for Charging Pump 'A'. The Step 4c Alternative Action identifies a hierarchy of systems to be used to provide this alternate cooling. The preferred method to use is the Chilled Water System. If this system is NOT available, then the Demin Water System should be used. If this system is NOT available, then the Fire Water System should be used.

Feedback A.
Plausible because 1st part is correct. Incorrect because the 2nd part is wrong - This would be the position of the valve if the operator did not apply 25 psi bias, or it did not exist [100%/50 psi error x (40psi) = 80%].
B.
CORRECT. According to IC-3 (p21, Rev 9), whether the Master Controller is in AUTO or MANUAL, both signals track each other, in order to ensure a bumpless transfer between controller operating modes. Because of this, when the operator places the Master Controller in MANUAL, the output will be retained from that point forward.
According to IC-3 (p20-21), the Master Pressure Controller receives an input from PT -444 and compares actual PZR pressure to an established reference pressure of 2235 psig. The Proportional wllntegral Controller develops an output signal that is used to control the variable output PZR Heaters, the two spray valves and one of three PZR PORVs. According to IC-3 (p22), the two spray valves are controlled with individual proportional 'controllers whose output increases as the output of the Master Pressure Controller increases. In other words, as pressure rises above its reference setpoint, the output of the Master Pressure Controller rises, causing the two Spray Valve Controller outputs to also rise. However, the Spray Valve Controllers are biased so they do NOT start to increase their output until a 25 psig error exists. Furthermore, the Spray Valves start to open as its controller rises above 0% output (+25 psi error) and are fully open when its controller rises to 100% output (+75 psi error). As PT-444 fails high with the Master Pressure Controller in AUTO, a positive error occurs causing the Master Pressure Controller Output to Increase. As this output increases, the variable input heaters go to minimum power, and when the error increases to 25 psi, the Spray Valve Controller outputs start to increase, opening the spray valves. When the operator takes the Master Pressure Controller to MANUAL, and 2275 psig, the Manual setpoint has tracked along with the Auto setpoint and generates a bumpless transfer. If no adjustments in the output are made (as stated in the conditions), the Master Pressure Controller Output will control PZR pressure as if the PZR pressure were 2275 psig.
With PZR pressure this high, the spray valves will open consistent with the existing error (40 psi). Since the PZR spray valves start to open at an error of 25 psi, and are fully open at a 75 psi error, and the Spray Valve Controller output varies proportionally, the spray valves should be open about 30% [100%/50 psi error x (40psi - 25 psi) = 30%].
C.
Plausible because this would be true if the controller's auto & manual signal did not track each other. Incorrect because the controller tracks the auto and manual signals allows for a bumpless transfer. 2nd part is also wrong. Plausible because this has been one method in which PZR heaters have been operated in the past: The spray valves have been open a small amount because one group of BU heaters are energized.
D.
Plausible because this would be true if the controller's auto & manual signal did not track each other. Incorrect because the controller tracks the auto and manual signals -
allows for a bumpless transfer. 2nd part is also wrong.
Plausible because this would be true in the absence of the bumpless transfer - the Master Controller Setpoint goes back to original and the spray valves were originally closed.

Feedback A.
Plausible because this is the correct tank volume if the unusable portion below the pump suction centerline is not considered. Incorrect because the unusable portion is considered in the T.S. minimum value. Also plausible 2nd part is correct; however not for the given value of 3085.45 gals.
B.
Plausible because this is the correct tank volume if the unusable portion below the pump suction centerline is not considered. Incorrect because the unusable portion is considered in the T.S. minimum value. 2nd part is plausible because it would be correct for the given value of 3085.45 gals. 2nd part is incorrect because actual volume considered in T.S. includes the unusable volume below the pump suction centerline.
C.
CORRECT. According to Technical Specification LCO 3.6.2.2, the NaOH Tank must have between 3140 and 3230 gallons to be OPERABLE. To obtain the actual volume of the tank the operator must use Figure VI-27 from the VCS Curve Book. A NOTE on Figure VI-27 indicates that the figure only includes volume above the pump suction centerline, and that the Technical Specification includes the total volume of the tank.
The figure identifies that the volume below the pump suction centerline is 79.61 gallons.
With the level at 97%, the operator must use the figure to arrive at the precise tank total volume. The curve demonstrates that the level, which reads in percent, changes linearly with volume (not including the volume below the pump suction centerline). A table to the right of the curve shows precise level measurements at 5% intervals. A check of this tables shows that the change in volume throughout the curve is 31.81 gallons/% level indication. At 97% the volume above the pump suction centerline can be determined by adding the volume at 95% (3021.83 by the table) and the volume associated with 2% more or 63.62 gallons. With this in mind the volume of the tank that is above the pump suction centerline is 3085.45. To obtain the total tank volume, which is what the Technical Specification uses, 79.61 gallons must be added to this volume.
When this is accomplished the total tank volume is found to be 3165.06 gallons, which satisfies the criteria of LCO 3.6.2.2.
D.
Plausible because this is the correct volume. Incorrect since the given volume meets the minimum LCO value.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
According to TB5 (p34, Rev 8), the Stator Cooling Runback will run the Turbine back at 25%/minute. Therefore, a 20 second runback will result in a power reduction of 8-9%.
When a downpower occurs, the SG level instrumentation, which monitors level within the downcomer region, will indicate an apparent loss of inventory, or "Shrink" within the SG, when in actuality the mass inventory is increasing (feed flow is greater than steam flow). According to IC-2 (p14), the effects of Shrink are most limiting at high power and maintaining the SG level within its normal band (as it was in the initial conditions) ensures that a sudden load rejection will NOT shrink level sufficiently to cause a reactor trip on the SG Low-Low level condition. With the feed flow adjusted to provide the B SG with 100% feed flow, a down power will result in a net inventory increase within the B SG. Although the initial level indication will decrease, the inventory will actually increase and result in an increasing level to the point in which P-14 actuates. With no operator action, the Turbine will trip, the reactor will trip, all three MFPs will trip and a FWIS will occur.
B.
Plausible because the 1 st part is correct. Also plausible because a Low-Low level should occur in SGs 'A' & 'c' after the Turbine Trip. Incorrect because SG 'B' will decrease, but NOT reach a Low-Low level following the Turbine Trip since it was at a higher than normal level when the trip occured.
C.
Plausible because because the 2nd part is correct. Also plausible because level will increase because FRV 'B' is in manual and will continue to feed SG 'B' at the original flow rate when the Shrink effect is over. Incorrect because level does not initially increase due to Shrink.
D.

Incorrect because level does not initially increase due to Shrink. Also plausible because a Low-Low level should occur in SGs 'A' & 'C' after the Turbine Trip. Incorrect because SG 'B' will decrease, but NOT reach a Low-Low level following the Turbine Trip since it was at a higher than normal level when the trip occured.

Feedback A.
Plausible because the Steam Dump Controller is set for 5.0 for a range of ruptured SG pressures of 1001-1100 psig. This range of pressure equates to a saturation temperature of approximately 544-556°F. Since CETs are given as 498°F, if the RCS pressure were 1000-1100, subcooling would indicate approximately 50°F (544-498=46; 556-498=58). Incorrect since given RCS pressure of 1750 psig results in subcooling of approximately 120°F. 2nd part is plausible since it is the actual correct procedural flowpath. It is incorrect if it is assumed that a Train A subcooling margin of 46°F is accurate. Subcooling less than 50°F indicates other problems exist and requires a transition to EOP-4.2.

C.
CORRECT. Given RCS pressure of 1750 psig = 1765 psia. Saturation temperature for 1750 psia is 61rF. Since CETs are 498°F; 617-498=119°F subcooling exists. At step 21 of EOP-4.0, the operator is asked to determine if RCS subcooling is> 50°F. Based on this, the procedure flowpath is determined. According to the WOG E-3 Background Document (HE3BG.doc, HP-Rev 2,4/30105), if> 50°F of RCS subcooling exists the.
operator continues in EOP-4.0. If not, an additional malfunction such as a LOCA is suspected because the cooldown step has been designed to place the plant in a condition where at least 20°F of subcooling exists, and coupled with the 30°F sucbooling allowed for instrument uncertainties, 50°F should exist.
D.
Plausible because the 1st part is correct. Given RCS pressure of 1750 psig = 1765 psia. Saturation temperature for 1750 psia is 61rF. Since CETs are 498°F; 617-498= 119°F subcooling exists. 2nd part is plausible since it is the correct procedural flowpath if a subcooling margin of 50°F is NOT established. Subcooling less than 50°F indicates other problems exist and requires a transition to EOP-4.2.

Feedback A.
CORRECT. At 1133 psig steam header pressure, the Steamline Power Reliefs shift from the Steam Dump Group 4 mode and open. With Tavg 557F and rising, Alternative Action of Step 3 of EOP-1.1 would apply. c) 1) & 2) require operation of the power reliefs if the Condenser is unavailable. Pressure would rise until the power reliefs swapped to the overpressure mode at 1133 psig, at which time the Tavg transient would be stopped.
B.
Incorrect since the Steamline Power Reliefs would have to be used without the Condenser Avaliable (C-9). Plausible because the main steam pressure is correct.
Also plausible because operation of the Condenser dumps is actually the preferred/first method addressed in the Alternative Action of Step 3 to control Tavg.
C.
Incorrect because pressure would only rise to 1133 psig. Plausible because the pressure is the value that main steam pressure would rise to if the power reliefs did not actuate at 1133 psig. This is the lift value of the lowest steam line safety valve.
Also plausible because these are the correct valves.

Plausible 1st part because the minimum Shutdown Margin requirement is applicable at all times in core life but the specific basis is for EOL when the Moderator Temperature Coeffecient provides the highest positive reactivity feedback. (Ref FSAR 15.4.2 Major Secondary System Pipe Rupture; Section 15.4.2.1.2 Analysis of Effects and Consequences ppg 15.4.21-15.4.23)
Plausible 2nd part because significant heat removal and positive reactivity effects from the negative moderator temperature feedback still occur but are the most severe because secondary inventory in the SG is not as great as exist at Wednesday, November 19, 2008 12:48:18 PM 91

Feedback A.
Plausible because the 2nd part is correct - with an auto-open signal present, the MD EFP RESET Switch must be reset (even though it is labeled EFP, not FCV), then the individual MCB control switches must be taken to MAN, and the Hagan controller must be adjusted to throttle the FCVs. Also plausible, because the FCVs receive an open signal from the same signals that start the associated EFP, except the MDEFP FCVs do not open when all 3 MFPs trip.
Incorrect because the MDEFP FCVs only open on loss of 1 DAl1 DB, Low-Low S/G level, and SI, NOT trip of 3/3 MFPs.
B.
Plausible because the 2nd half is true for normal plant conditions - in the absence of an auto-start condition of the MDEFPs, all that is required to throttle the FCVs is to take the control switch to MAN and adjust the Hagan controller. Also plausible, because the FCVs receive an open signal from the same signals that start the associated EFP, except the MDEFP FCVs do not open when all 3 MFPs trip.
Incorrect because the MDEFP FCVs only open on loss of 1 DAl1 DB, Low-Low S/G level, and SI, NOT trip of 3/3 MFPs.
C.
CORRECT. The MDEFP FCVs open on the same signals that start the MDEFPs (loss of 1 DAl1 DB, Low-Low S/G level, and SI [NOT trip of 3/3 MFPs]). With an auto-start signal present fro the MDEFPs, the operator must take the MD EFP RESET Switch to RESET, the individual MCB control switches must be taken to MAN, and the Hagan controller must be adjusted to throttle the FCVs (see IB-3, pages 31-34, and Figure IB3A).
D.

Feedback A.
Plausible because temperature may drop below the limit during this event, and would present a challenge to the Integrity Critical Safety Function that will require action by the operator within the body of EOP-6.0. Incorrect because this situation is an anticipated condition within EOP-6.0 during the SG depressurization. According to Step 19.c of EOP-6.0, the operator must verify the RCS Tcolds are greater than 280°F during the SG depressurization. If so, the crew is directed to stop the depressurization.
B.
Plausible because a challenge to Subcriticality Critical Safety Function may occur during this event and, is so, will require action by the operator within the body of EOP-6.0.
Incorrect. According to Step 20 of EOP-6.0, the operator is to monitor both the Intermediate and Source Range Nuclear Instrumentation channel startup rates during the SG depressurization and ensure that they are zero or negative. If they are positive, the depressurization should be stopped and the RCS allowed to heat up to add negative reactivity. The operator should NOT transition out of EOP-6.0 based on this indication.
According to EOP-12.0 (Rev 12), this situation will result in an Orange Path on Subcriticality, the highest Critical Safety Function.
C.
Plausible because this may occure during the depressurization and is part of the criteria that would require immediate transition to EOP-15.0 from other procedures. Incorrect because Step 19 of EOP-6.0, the operator is to simply verify SG levels >30%. If not, the Alternative Action directs maintaining max EFW flow until at least 1 SG is >30%, not transitioning out of EOP-6.0.
D.
CORRECT. According to Note 3 prior to Step 1 of EOP-6.0 (Rev 21), the Critical Safety Function Status Trees should be monitored for information only during the performance of the EOP. It specifically states that procedures referenced from the status trees should NOT be referenced. According to Step 25 of EOP-6.0, the operator is directed to evaluate CETs and if> 1200°F transition to SACRG-1. According to the WOG ECA-O.O Background Document (HECAOOBG.doc, HP-Rev.2, 4/30105, p133), this condition indicates that all attempts to restore core cooling have failed and core damage cannot be avoided. Transition to Severe Accident Control Room Guideline Initial Response - Step 1 is required. This is the ONLY time that the operator is directed to transition from EOP-6.0 with power established to at least one AC ESF Bus.

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION)
Feedback A.
Plausible because Charging Pump 'B' does not receive a start signal on a blackout signal alone. Additionally, Charging Pump 'C' receives a trip signal (on output #5 from the ESFLS - which occurs at T = 0 on the blackout event) on a blackout if it is running with its same train Charging Pump breaker racked up. NO pumps would be running if Charging Pump 'A' breaker were racked up. Incorrect because Charging Pump 'C's' breaker is closed and is NOT tripped (since 'A' breaker is racked down) at the start of the event. When power is restored to the Bus 1DA, Charging Pump 'C' will restart.
B.
This is plausible because ONLY the Train 'B' ESFLS has correctly completed its sequence. It is a common misconception that the Charging Pump starts on the ESFLS sequence, not as soon as power is restored (via Load Block #1). Incorrect because the Charging Pump 'B' breaker is open at the start of the event, and a blackout signal alone will NOT start a Charging Pump. Also incorrect since, when power is restored to Bus 1DA, Charging Pump 'C' will restart.
C.
According to GS2 (p48-52, Rev 15), the ESFLS will respond to one of four events: (1) an undervoltage on the ESF Bus, (2) an SI actuation, (3) an SI actuation followed by an undervoltage on the ESF Bus, and (4) an undervoltage on the ESF Bus followed by an SI actuation. When the ESFLS is actuated it will trip loads, block others from tripping, realign equipment, and load components onto the ESF Bus in a series of 8 steps, dependent upon the initiating signal. The undervoltage on the ESF Bus, known as a blackout, is the event established in the conditions above. According to GS-2 (p51-52),
12 status lights per train are provided on the MCB to alert the operator to the status of the ESFLS. Each Train has a similar set of status lights. With the conditions established above, it is apparent that the B ESFLS has initiated its blackout load sequence, carried out all eight loading steps, and completed its sequencing. On the other hand, train 'A' has initiated its blackout load sequence, carried out the first five of the loading steps and failed to complete any further action. According to GS-2 (p58),
the blackout signal alone does NOT start the Charging Pumps, but only trip and lockout Charging Pump 'c' under certain conditions (Charging Pump Breaker on the same train racked up). Since Charging Pump 'C' is racked up on Bus 1DA, and the Charging Pump 'A' breaker is racked down, the Charging Pump 'C' breaker will NOT trip. The Charging Pump 'C' breaker will be closed at the start of the event, and remain closed throughout the event. When the DG 'A' breaker closes in on ESF Bus 1DA, Charging Pump 'C' will re-energize. On the other hand, since Charging Pump 'B' is NOT running, even though the Train 'B' sequencer completes is sequencing correctly, its breaker will NOT be closed on a blackout signal alone.
D.
Plausible because 'B' would have started if it were running prior to the LOOP. Alos plausible because Charging Pump 'C' is correct. Incorrect because Charging Pump 'B' breaker is open at the start of the event, and a blackout signal alone will NOT start a Charging Pump. This is also plausible because only the B Train ESFLS has correctly completed its sequence. It is a common misconception that the Charging Pump starts on the ESFLS sequence, not as soon as power is restored (via Load Block #1).

Feedback A.
According to GS-2 (p44-4S, Rev 1S) operators are alerted to problems with inverters/instrument panels primarily through the receipt of annunciators on the MCS.
Operators would respond to the event according to the directions of the Annunciator Response Procedure and dependent upon the symptoms of response of plant components to the failure. According to IC-S (pSO, Rev 9), APN-S901 provides indication and control power to Intermediate Range Channel NI-3S. If Control Power is lost the Reactor Protection System will generate a trip signal on High Intermediate Range Flux in this instrument. According to IC-9 (p36, Rev 13), when 1 of 2 Intermediate Range instruments generate a trip signal with 3 of 4 power ranges less than 10% power, and automatic reactor trip is generated. Because of this, the reactor will trip, and the crew will enter EOP-1.0, Reactor Trip/Safety Injection Actuation. For the given conditions, annunciator INV 1/2 TROUBLE (XCP-636, 1-S) will alarm.

C~ Reduce total EFW flow to no less than 450 GPM to stop the cooldown.
D. Reduce EFW flow to each SG to no less than 50 GPM to stabilize Tavg at the no load value.
Feedback A.
Plausible because EFW flow adjustments are contingent on SG level and operator may elect this option if cooldown is not in progress.
Incorrect since cooldown is occurring, the operator should throttle to 450 GPM.
B.
Plausible because it would be the correct action if any SG was> 26% [40%].

Feedback A.
CORRECT. According to AOP-220.1 (Rev 2), Step 9b, the operator will be required to control EFW Flow Control Valves manually to maintain Steam Generator Narrow Range levels between 55-65% in a post-reactor trip situation (Note that this step of the AOP can only be implemented if a reactor trip has occurred at step 4). The second NOTE before Step 9 states that if EFW Pumps must be stopped to control SG level, as is the case stated in the condition of the question, level should be allowed to decrease to 30%
(Le. expand the SG Narrow Range level control range), and the pumps should be alternated, to avoid exceeding the starting duty.
B.
Plausible because EOP-1.0, Attachment 3, Step 4 directs isolation of blowdown and sampling, which will result in longer times between the need to refill the SGs. Also plausible because the 1 st part is correct. Incorrect because there are NO action steps within AOP-220.1 to isolate blowdown and sampling from the Steam Generators.
C.
Plausible because the SG PORVs must be manually controlled at Step 10 of the AOP.
D.
Manually opening only one PORV at a time will retain overall SG inventory for a longer period of time. Also plausible because the 2nd half is correct. Incorrect because Step 10 of the AOP directs that all three SG power reliefs be manually opened to control RCS temperature at 55rF. Also, the Caution prior to this step warns the operator about establishing a temperature differential between the RCS loops of greater than 25°F. CAUTION - Step 10 further warns against an unbalanced steamload, which could causea Steam line DEL TA-P SI.

Given the following plant conditions:
Following a Control Room Evacuation, the plant is being controlled in accordance with GOP-8, Plant Shutdown from Hot Standby to Cold Shutdown with the Control Room Inaccessible Mode 3 to Mode 5.
The CRS has directed that the RCS be borated to raise boron concentration by 300 ppm.
Present RCS boron concentration is 100 ppm.
MVT-81 04, Emergency BA Flow Control Valve, has been opened.
Boric Acid Transfer Pump 'B' has been started.

REFERENCES PROVIDED A. FI-122B, CHARGING FLOW GPM; 30 gpm for 127 minutes B. FI-122B, CHARGING FLOW GPM; 55 gpm for 52 minutes C. FI-110A; EMERGENCY BA FLOW GPM; 30 gpm for 127 minutes.
D~ FI-110A; EMERGENCY BA FLOW GPM; 55 gpm for 52 minutes.
Feedback.
A.
Plausible because FI-122B is also on the CREP and would be used if emergency borating by gravity drain. Incorrect since FI-110A would be used for emergency borating through MVG-81 04. This is plausible because other procedures such as AOP-106.1 and EOP-1.1 require the operator to verify flow on FI-11 OA to be > 30 gpm to verify that Emergency Boration is occurring. The 127 minutes is based on a common error in reading Figure 111-2 of the VCSNS Curve Book. The common error is that the column is incorrectly determined by adding the amount of change to the initial concentration (in this case, 300 + 100 = 400) instead of simply subtracting the final -
initial. Based on this error, the amount of acid to be added = 2964 X CF of 1.28 for the temperature decrease (down to 200°F) = 3793.92 gallons. At 30 gpm, this would take approximately 126.5 minutes (Time = 3793.92 gallons/30 gpm=126.46 minutes).

QUESTIONS REPORT forVCS 2009 NRC RO WORKSHEET (AFTER CHANGES FROM VALIDATION) because FI-122 is not the Flow indicator utilized in GOP-8.0 Attachment XX B.
Plausible because FI-122B is also on the CREP and would be used if emergency borating by gravity drain. Also plausible because the 2nd part is correct. According to IC-10 (p11, Rev 6), the Emergency BA Flow (FI-110A) is provided on the B CREP.
According to GOP-8, Attachment XX, the operator is required to verify flow on FI-110A, and then close MVT-8104 after the required amount of Boron has been injected.
According to Figure 111-2, RCS Boration, Gallons (VB) of Boric Acid Required (Rev 11/11/94) in the V.C. Summer Unit Number One Station Curve Book an increase of 300 ppm from the present RCS Boron Concentration of 100 ppm (100 ppm on the X Axis
{Vertical} and 300 ppm on the Y Axis {Horizontal}) will require an addition of 2207 gallons. Applying the CF of 1.28 for the temperature decrease results in 2824.96 gallons of Boric Acid required (2207 X 1.28 = 2824.96). The addition of 2824.96 gallons of Boric Acid, which is being added at 55 gallons per minute, will require approximately 52 minutes (Time = 2824.96 gallons/55 gpm = 51.36 minutes).
Incorrect because FI-122 is not the flow indicator utilized in GOP-8.0, Attachment XX.
C.
Plausible because the 1 st part is correct. Also plausible because other procedures such as AOP-106.1 and EOP-1.1 require the operator to verify flow on FI-110A to be>
30 gpm to verify that Emergency Boration is occurring. The 127 minutes is based on a common error in reading Figure 111-2 of the VCSNS Curve Book. The common error is that the column is incorrectly determined by adding the amount of change to the initial concentration (in this case, 300 + 100 = 400) instead of simplay subtracting the final -
initial. based on this error and applying the CF of 1.28 for the temperature decrease, the amount of acid to be added = 3793.92 gallons. (2964 X 1.28 = 3793.92). At 30 gpm, this would take approximately 127 minutes (Time = 3793.92 gallons/30 gpm
=126.46 minutes).
Incorrect because this would result in MORE than the minimum boration.
D.
CORRECT.
According to IC-10 (p11, Rev 6), the Emergency BA Flow (FI-11 OA) is provided on the 'B' CREP. According to GOP-8, Attachment XX, the operator is required to verify flow on FI-110A, and then close. MVT-8104 after the required amount of Boron has been injected. According to Figure 111-2, RCS Boration, Gallons (VB) of Boric Acid Required (Rev 11/11/94) in the V.C. Summer Unit Number One Station Curve Book an increase of 300 ppm from the present RCS Boron Concentration of 100 ppm (100 ppm on the X Axis {Vertical} and 300 ppm on the Y Axis {Horizontal}) will require an addition of 2207 gallons. Applying the CF of 1.28 for the temperature decrease (down to 200°F) results in 2824.96 gallons of Boric Acid required (2207 X 1.28 = 2824.96). The addition of 2824.96 gallons of Boric Acid, which is being added at 55 gallons per minute, will require approximately 52 minutes (Time = 2824.96 gallons

Feedback A.
Step 5 of AOP-301.1, Response to Electrical Grid Issues, (Rev. 0), directs the operator to ensure that the Main Generator loading is within the limits of the capability curve, and if NOT, make adjustments to the main Generator Voltage to ensure that the Main Generator MVARs remain within limits. According to TB-3 (p49-50, Rev 6), after synchronizing the Main generator to the grid, with the Voltage Regulator in AUTO, the GEN FIELD VOLTS ADJ is used to change a reference voltage signal, allowing the automatic regulator to adjust Exciter output and control reactive load on the Main Generator. According to TB-3 (p19-20), the Main Generator EX2000 Voltage Regulator employs three regulators, or cores; Core 1, Core 2 and Core 3. Where all three Cores are identical, Cores 1 and 2 are generating control signals, while Core 3 generates a supervisory & protection signal. When operating, either Core 1 or Core 2 is controlling the excitation of the Main Generator. While one Core is providing the control signal to the Exciter, the backup Core is generating the same signal but providing it to a dummy load resistor. In essence, this creates a lihot" backup that can be signaled to take control of the process immediately by a supervisory circuit. Core 3 is the supervisory circuit. According to TB-3 (p20), when Core 1 or Core 2 fails, Core 3 senses this and takes appropriate action. If the failed Core is the controlling Core, Core 3 generates a "bumpless transfer" to the standby Core. If the failed Core is the standby Core, Core 3 senses this and generates an alarm.
B.
Plausible because the 1 st part is correct. Also plausible because, according to TB-3 (p23), if a bumpless transfer failed to occur, Core 3 will function to trip both the Main Generator and the Generator Field Breaker. Incorrect because a protection action is NOT needed in the conditions established in the stem. The bumpless transfer action will occur before the protective action. The protective action will occur if both Core 1 and Core 2 have failed.
C.
Plausible because the 2nd half is correct.

3A is powered from 1 DA 1 and the Supplemental is powered from 1081, both of which are available.
D.
Plausible if non-vital power was available and 1 DA 1 (vs. 1DA2) were OOS. Also plausible because the 2nd part is correct. Incorrect because non-vital power is lost and the 38 lAC is powered from 1A 1.

Given the following plant conditions:
(
(
100% power A fire occurs in the transformer to Bus XSW-1 C2, causing the bus to de-energize.
The Fire Brigade responds 3 minutes after the event - routing, pressurizing and using fire hoses to fight the fire.
Which ONE (1) of the following describes the response of the fire pumps to this event?
A. The Electric Fire Pump started within one minute of the fire.
B~ The Diesel Fire Pump started within one minute of the fire.
C. The Electric Fire Pump started when the fire hoses were used.
D. The Diesel Fire Pump started when the fire hoses were used.
Feedback A.
Plausible because the electric fire pump would auto start on lowering fire header pressure as fire hoses were pressurized and used to fight the fire. Incorrect because the electric fire pump is powered from XSW-1C2. Therefore, the Electric Fire Pump will NOT start because the bus is de-energized. Also incorrect because fire hoses are not pressurized until 3 minutes into the event as stated in the conditions.
B.
CORRECT: According to GS-11 (p14), the Diesel Fire Pump receives electrical power for the Diesel Controller from APN-1C2; a power panel powered from XSW-1C2 (Table GS1.6). When AC power is lost to the diesel controller, the electronic controller initiates an 18 second time delay, after which the alarm circuit and the engine is automatically started (p16). Therefore the Diesel Fire Pump will start within one minute of the fire event.
C.

Feedback A.
Plausible because EOP-16.0 would not have been entered in the first place if EOP-1.0 had not already been imlemented/completed (this is an Entry Condition to EOP-1.S).
Incorrectbecause the given condition in Choice A is a likely situation that the EOP is designed to deal with effectively, so EOP-1.S would be unnecessary. EOP-16.0 is a RED Path Functional Response Procedure. According to OAP-103.4 (Step 6.17.i, Rev 0), once an FRG is entered due to a RED path, that procedure is executed to its completion unless a CSF of higher priority is challenged or the crew is directed out of the procedure. The WOG ES-O.O Background Document confirms this by stating that Rediagnosis only applies to Optimal Recovery Procedures and NOT to Functional Response Procedures (HESOOBD.doc, HP-Rev 2, 4/3010S, p1). In the Large Break LOCA event, EOP-16.0 should NOT be used in its entirety to stabilize the plant, and step 1 of this procedure will diagnose the LBLOCA Event and return the operator to the Procedure and Step in effect. The use of EOP-1.S in this situation would be inappropriate.
B.
Plausible because EOP-1.1 would not have been entered in the first place if EOP-1.0 had not already been imlementedlcompleted (this is an Entry Condition to EOP-1.S).
Incorrect because, if the crew has transitioned to the GOP from EOP-1.1, SI is NOT in service, nor is it required, and the Entry Conditions for EOP-1.S are NOT met.
C.
CORRECT. According to the EOP-1.S (Rev 2) Entry Conditions, the procedure can be entered based on operator judgment, but ONLY after completing EOP-1.0. According to Note 1a of EOP-1.S, the procedure should be used ONLY if SI is in service or required. According to the purpose statement of EOP-1.S, the procedure is used to determine or verify which procedure is most appropriate for restoring stable plant conditions. If the crew is operating in EOP-4.0, then EOP-1.0 has been completed and SI is in service. According to the Purpose Statement, the CRS can confirm that EOP-4.0 is the appropriate procedure by using EOP-1.S.
D.
Plausible because OAP-103.4, Enclosure C states that EOP-1.S is applicable in Modes 1-4. Incorrect because the Entry Conditions are NOT satisfied to use EOP-1.S (EOP-1.0 has NOT been completed. The crew must remain in AOP-112.1.

Feedback A.
Plausible because it is a set or parameters that could exist after a LOCA and because 2 S/Gs are below the criteria for EXTREME challenge with NO adverse containment conditions. Given value of RB radiation levels is the correct number for integrated dose, but the wrong units. Incorrect because the CSF does NOT have an Extreme Challenge because there is at least one SG NR Level> 30% with a normal RB atmosphere.
B.
Plausible because it is a set or parameters that could exist after a LOCA and because 1 S/G is below the criteria for EXTREME challenge with NO adverse containment conditions. Given value of RB radiation levels is above the correct number for dose rate, but the wrong units. Incorrect because the CSF does NOT have an Extreme Challenge because there is at least one SG NR Level> 30% with a normal RB atmosphere.
C.
CORRECT. According to Attachment 3 of EOP-12.0 (Rev 12), Heat Sink, an EXTREME challenge (Red Path) on Heat Sink will exist if Total EFW is < 450 gpm (which is the case in all sets of conditions) and there is NOT at least one SG NR Level>
30% with a normal RB atmosphere, or there is NOT at least one SG NR Level> 50%
with an adverse RB atmosphere. According to OAP-103.4 (Step 6.8, Rev 0), an adverse RB environment is an environment where RB Pressure is presently> 3.6 pSig OR an environment in which RB Radiation levels have exceeded an integrated dose of 105 R (OR 1000 Rlhr if the IPCS is unvailable) at anytime during the event. Given value of RB radiation levels is the correct number for integrated dose, but the wrong units.
The CSF has an Extreme Challenge because there is NOT at least one SG NR Level>
50% with an adverse RB atmosphere.
D.
Plausible because it is a set or parameters that could exist after a LOCA and because 2 S/Gs are below the criteria for EXTREME challenge with adverse containment conditions. Incorrect because the CSF does NOT have an Extreme Challenge because there is at least one SG NR Level> 50% with an adverse RB atmosphere. Given value of RB radiation levels is above the correct number for dose rate, but the wrong units.
NOTE: The reason that RB Rad Levels are provided is to lend some credibility between Choices A & B and between Choices C & D. Without these values, Choices A & Bare practically the same. Units are provided in mrlhr to be able to provide numbers which meet the intgrated does value OR exceed the instantaneous dose rate values for adverse coniditions.

According to OAP-1 03.4 (Step 6.S, Rev 0), an adverse RB environment is an environment where RB Pressure is presently> 3.6 psig OR an environment in which RB Radiation levels have exceeded an integrated dose of 105 R (OR 1000 Rlhr if the IPCS is unvailable) at anytime during the event. Given value of RB radiation levels is the correct number for integrated dose, but the wrong units.
The CSF has an Extreme Challenge because there is NOT at least one SG NR Level>
50% with an adverse RB atmosphere.
D.
Plausible because it is a set or parameters that could exist after a LOCA and because 2 S/Gs are below the criteria for EXTREME challenge with adverse containment conditions. Incorrect because the CSF does NOT have an Extreme Challenge because there is at least one SG NR Level> 50% with an adverse RB atmosphere. Given value of RB radiation levels is above the correct number for dose rate, but the wrong units.
NOTE: The reason that RB Rad Levels are provided is to lend some credibility between Choices A & B and between Choices C & D. Without these values, Choices A & Bare practically the same. Units are provided in mr/hr to be able to provide numbers which meet the intgrated does value OR exceed the instantaneous dose rate values for adverse coniditions.

Feedback A.
Plausible because this would be correct for other valves in the RHR system that do NOT have a power lockout, such as MVG-8887 A, RHR Hot leg Cross-Connect Valves.
Incorrect because 8888A does have a power lockout. The switch must be taken to ON in order to power the valve.
B.
Plausible because other valves in the RHR System, such as MVG-8809A, receive a signal to open on an SI. Also plausible because SI Reset normally occurs prior to operation of 8888A. Incorrect since MVG-8888A does NOT receive a signal to position on an SIS; therefore reseting SI does not affect the ability to operate this valve.
C.
According to AB-7 (p32-33, Rev 19), both the RHR to Cold leg Injection Isolation Valves, MVG-8888A and B, are maintained OPEN during normal power operation, and to prevent inadvertent closure power lockout switches are used to interrupt power to their motors. These switches are normally maintained in the OFF position. According to AB-10 (p44, Rev 13), White Status lights for each valve having a Power lockout are located on the MCB to show the actual valve position. These lights are powered from the opposite train (i.e. Train 'B' provides power for the status light indicating the position of the Train 'A'valves). In accordance with Table AB7.7, the operator must perform a two-switch operation to operate the valve; (1) the power lockout must be overridden by the MCB switch and then the valve must be manipulated using its respective MCB Switch.
D.
Plausible because depressing both SI Reset pushbuttons is the normal method of resetting SI and this action is performed before manipulating RHR valves in the EOPs.
Also plausible because other valves in the RHR System, such as MVG-8809A & B, receive a signal to open on an SI - both SI Reset push buttons must be reset to operate these valves. Incorrect because MVG-8888A does NOT receive a signal to position on an SIS; therefore reseting SI does not affect the ability to operate this valve.

Plausible because this would be correct for other valves in the RHR system that do NOT have a power lockout, such as MVG-8887A, RHR Hot Leg Cross-Connect Valves.
Incorrect because 8B8BA does have a power lockout. The switch must be taken to ON in order to power the valve.
B.
Plausible because other valves in the RHR System, such as MVG-8809A, receive a signal to open on an 81. Also plausible because 81 Reset normally occurs prior to operation of SBSBA. Incorrect since MVG-8888A does NOT receive a signal to position on an SIS; therefore reseling 51 does not affect the ability to operate this valve.
C.
According to AB-? (p32-33, Rev 19), both the RHR to Cold Leg Injection Isolation Valves, MVG-8888A and B, are maintained OPEN during normal power operation, and to prevent inadvertent closure power lockout switches are used to interrupt power to their motors.

Feedback A.
Pausible because this is one of the actions in EOP-1S.0 and, since the MFPs are available, the crew may still be making efforts to restore feed flow using MFW while implementing Bleed and Feed. Incorrect since both the 'A' and 'B' SG Wide Range Levels are < 1S%, Bleed and Feed is required NEXT.
B.
Pausible because this is one of the actions in EOP-1S.0 and, since two MFBPs and a Condensate pump are running, the crew may still be making efforts to restore feed flow using condensate flow while implementing Bleed and Feed. Incorrect since both the 'A' and 'B' SG Wide Range Levels are < 1S%, Bleed and Feed is required NEXT.
C.
Plausible because, according to the FR-H.1 Background Document (HFRH1 BG.doc, HP-Rev 2, 4/3010S, pSO), Feed and Bleed is the process of manually initiating high pressure safety injection and permitting the automatic cycling of the PZR PORVs at their set pressure to vent RCS inventory and provide decay heat removal and core cooling. Incorrect since VCSNS uses the Bleed and Feed methodology, not the Feed and Bleed.
D.
According to the WOG F-0.3 Background Document (HF03BG.doc, HP-Rev. 2, 4/3010S) and OAP-103.2 (Rev 0), a Secondary Heat Sink has been defined as a total EFW flow of> 4S0 gpm, or at least one SG Narrow Range Level> 30% [SO%]. The conditions have established that neither exist by identifying the existence of a Red Path on Heat Sink, the fact that attempts to restore EFW have been unsuccessful, and all three Wide Range levels are consistent with Narrow Range Levels that are off-scale low.
According to EOP-1S.0 (Rev 13), the strategy for restoring a Secondary Heat Sink involves two phases, the first in which the operator attemptsto restore a Secondary Heat Sink by restoring EFW, MFW and Condensate in that order of preference; and the second which abandons the attempt to restore a Secondary Heat Sink, and initiates a Bleed and Feed cooling posture. The criteria for differentiating between the two phases, is identified in Caution - Steps 4 through 16, and states as follows: If Wide Range level in any two SGs is < 1S% [2S%] OR PZR pressure is greater than 233S psig due to loss of Secondary Heat Sink, steps 17 through 24 should be immediately initiated for bleed and feed cooling. In this case, although the PZR pressure criteria is not met for Bleed and Feed, the SG Wide Range Level criteria is, and bleed and feed must be initiated. According to the FR-H.1 Background Document (HFRH1 BG.doc, HP-Rev 2, 4/3010S, pSO), Bleed and Feed is the process of manually initiating high pressure safety injection and manually opening the PZR PORVs to allow the injection of sufficient water to provide for decay heat removal and core cooling; and Feed and Bleed is the process of manually initiating high pressure safety injection and permitting the automatic cycling of the PZR PORVs at their set pressure to vent RCS inventory and provide decay heat removal and core cooling.

D.
According to the WOG F-0.3 Background Document (HF03BG.doc, HP-Rev. 2, 4/30105) and OAP-103.2 (Rev 0), a Secondary Heat Sink has been defined as a total EFW flow of> 450 gpm, or at least one SG Narrow Range Level> 30% [50%]. The conditions have established that neither exist by identifying the existence of a Red Path on Heat Sink, the fact that attempts to restore EFW have been unsuccessful, and all three Wide Range levels are consistent with Narrow Range Levels that are off-scale low.
According to EOP-15.0 (Rev 13), the strategy for restoring a Secondary Heat Sink involves two phases, the first in which the operator attempts to restore a Secondary Heat Sink by restoring EFW, MFW and Condensate in that order of preference; and the second which abandons the attempt to restore a Secondary Heat Sink, and initiates a Bleed and Feed cooling posture. The criteria for differentiating between the two phases, is identified in Caution - Steps 4 through 16, and states as follows: If Wide Range level in any two SGs is < 15% [25%] OR PZR pressure is greater than 2335 psig due to loss of Secondary Heat Sink, steps 17 through 24 should be immediately initiated for bleed and feed cooling. In this case, although the PZR pressure criteria is not met for Bleed and Feed, the SG Wide Range Level criteria is, and bleed and feed must be initiated.

- 73. G2.3.7001INEW//LOWERJIRO/SUMMERJ2/2009INO Given the following plant conditions:
Mode 5 RHR is in service.
A worker is assigned a task in the AB 436' West Penetration.
Ar:' RWP was approved for the task and a STAY TIME Card was issued.
Which ONE (1) of the following applies when the STAY TIME is reached?
A. The worker must exit the area until a STAY TIME extension is approved by the job coverage HP Technician.
B~ The worker must exit the area until a STAY TIME extension is approved by an HP Supervisor.
- c. The worker may continue working until the ED alarm actuates then exit the area.
D. The worker may continue working, monitor the ED frequently, and call HP if a STAY TIME extension is required.
Feedback A.
Plausible because the 1 st part is correct. Also plausible because the job coverage technician initially completes the Stay Time Card (see HPP-0401, 4.1.4.G.7)
Incorrect because STAY TIME extensions can be granted only by a HP Supervisor.
B.
CORRECT. STAY TIME is a required part of the RWP if certain conditions are met.
HPP-401 allows an HP Supervisor to approve STAY TIME Extensions provided certain criteria are met.
C.
Plausible because this would be the RWP required action if the ED alarm actuated before the STAY TIME limit was reached. "Continue working" is plausible because, under normal conditions, an individual would not have to exit the area unless the ED actually alarmed.
Incorrect because the STAY TIME is based on a time less than the ED alarm setpoint.
D.
"Continue working" is plausible because, under normal conditions, an individual would NOT have to exit the area unless the ED actually alarmed. Also plausible because monitoring the ED frequently is NOT unique to these conditions.
Incorrect because an HP Supervisor would need an actual ED reading to determine if the dose limit has been exceeded before issuing an extension - a call would not suffice.
"Calling HP" is plausible because there are many radiological conditions that require HP to be called/contacted. Also plausible because HP would be notified.
