Proposed Answer:
B Explanation (Optional):
A. Incorrect
- Torus suction valves must be full open before the MO
-2500 CST Suction automatically closes.
The first part of the distracter is correct, however the second part is not correct , but plausible
, if the candidate assumes that both valves cycle at the same time to prevent having both valves fully open at the same time and cross connecting the CST and torus. B. Correct - The suction path will automatically shift from the Condensate Storage Tanks to the Suppression Pool on a low level in the Condensate Storage Tanks of 1' 1/4".
The RCIC inboard and outboard torus suction valves MO
-2516 and MO
-2517 open automatically on low CST level, and when both valves are fully open, MO
-2500 CST Suction automatically closes.
C. Incorrect
- RCIC suction valves will NOT swap on a high Suppression Pool level
. Plausible because HPCI suction valves will swap on a high Suppression Pool level and if the candidate assumes that both valves cycle at the same time to prevent having both valves fully open at the same tim e and cross connecting the CST and torus
.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 2 D. Incorrect
- RCIC suction valves will NOT swap on a high Suppression Pool level, plausible because HPCI suction valves will swap on a high Suppression Pool level.

- effect relationships between SHUTDOWN COOLING SYSTEM (RHR SHUTDOWN COOLING MODE) and the following: Reactor pressure Proposed Question:
RO Question # 2 Following a reactor scram
, the following conditions exist: Reactor level
+1 90 inches Reactor pressure 1 39 psig Drywell pressure 1.72 psig Based upon the given conditions, which ONE of the following Residual Heat Removal valves is closed and prevented from opening?
A. MO-2006 , RHR LOOP "A" TORUS SPRAY HEADER ISOLATION B. MO-190 8, RHR SHUTDOWN COOLING ISOLATION VALVE C. MO-2007 , RHR LOOP "A" TORUS COOLING AND TEST RETURN HDR ISOLATION D. MO-1940, RHR HX 1E-201B BYPASS VALVE Proposed Answer:
B Explanation (Optional):
A. Incorrec t - For the given conditions MO-2006 is able to be opened, the valve is isolated when containment pressure is > 2 psig.
Plausible because the candidate may assume that a high Drywell pressure is needed to place Torus sprays in service.
B. Correct - Of the signals listed, only the reactor pressure signal causes an RHR isolation/interlock. This high
-pressure interlock prevents the SDC section of piping from being over pressur iz ed. A reactor pressure of approximately 135 psig (per ARP 1C03B B-4 this pressure is approximately 100 psig) initiates an isolation of SDC suction valves MO-1908 and 1909. The LPCI piping is also protected from over pressurization, but the setpoint is 4 50 psig. C. Incorrect
- For the given conditions MO-2007 is able to be opened
, the valve is isolated when containment pressure is > 2 psig.
Plausible because the candidate may assume that a high Drywell pressure is needed to place Torus sprays in service.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 4 D. Incorrect
- MO-1940 has an automatic open function on a LPCI initiatio n signal. It does NOT have an auto close function.

Proposed Answer:
C Explanation (Optional):
A. Incorrect
- The electrical power supply to the backup compressor is lost due to the 1A3 lockout. Air Compressor 1K1 power source will NOT start and must be shifted to its' alternate power source.
B. Incorrect
- The electrical power supply to the backup compressor is lost due to the 1A3 lockout. Air Compressor 1K1 power source will NOT start and must be shifted to its' alternate power source.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 6 C. Correct - The electrical power supply to the backup compressor is from essential bus, 1B33 or 1B45. Bus 1B33, the normal source, is powered from Essential Bus 1A3, a lockout will prevent the 1G31 Diesel from supplying the bus therefore Air Compressor 1K1 power source must be shifted to its' alternate power source. The power source is selected from either 1B33 or 1B45, the alternate source, via a manually selectable power transfer switch 1N3312.
D. Incorrect
- Pressure select switch HSS
-3002 is a two position switch used to determine the operating mode of the backup compressor. The backup compressor is normally maintained in the STANDBY status. It will NOT have an effect until the power supply is transferred to the alternate source.

Level RO SRO Tier # 2 Group # 1 K/A # 263000 K2.01 Importance Rating 3.1 Knowledge of electrical power supplies to the following: Major D.C. loads Proposed Question:
RO Question # 4 The plant is at rated conditions with the electric plant in its normal full power lineup when a fault results in a loss of 125 VDC bus 1D20.
While in this condition, a loss of coolant accident occurs and the reactor scrams.
Following the scram, the Main Turbine is manually tripped.
Which one of the following is correct regarding high pressure systems or components that are available to control RPV level from the control room?
A. HPCI and both Reactor Feed Pumps B. RCIC and both Reactor Feed Pumps C. HPCI and "A" Reactor Feed Pump ONLY D. RCIC and "A" Reactor Feed Pump ONLY Proposed Answer:
D Explanation (Optional):
A. Incorrect: HPCI will not function without 125 VDC Div II power (bus 1D20). Plausible if the candidate confuses the power supplies of HPCI and RCIC (Div 1 versus Div 2). Additionally only the "A" RFP will be available because bus 1A2 will de
-energize when the turbine is tripped due to the loss of control power. Plausible if the candidate does not understand the response of the electric plant to a loss of DC following a turbine trip.
B. Incorrect: Only the "A" RFP will be available because bus 1A2 will de
-energize when the turbine is tripped due to the loss of control power.
C. Incorrect: HPCI will not function without 125 VDC Div II power (bus 1D20). Plausible if the candidate confuses the power supplies of HPCI and RCIC (Div 1 versus Div 2).
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 8 D. Correct: RCIC will still be available with a loss of 125 VDC. Although RCIC suction will transfer to the torus and one channel of isolation logic is disabled, it is still available for level control. Additionally when the turbine trips, bus 1A2 will de
-energize due to the loss of control power supplied by Div II 125 VDC. However, 1A1 still has control power and will transfer to the off-site power source which will supply power to the "A" RFP.

Level RO SRO Tier # 2 Group # 1 K/A # 209001 K3 01 Importance Rating 3.8 Knowledge of the effect that a loss or malfunction of the LOW PRESSURE CORE SPRAY SYSTEM will have on following: Reactor water level Proposed Question:
RO Question # 5 The plant is operating at 100% power when a small "A" recirc loop leak results in drywell pressure rising to 3 psig. The following conditions exist: The reactor is scrammed and all rods are fully inserted RPV level is stabilized at 190 inches range using high pressure injection systems Drywell pressure remains at 3 psig RPV pressure is 900 psig and slowly lowering The CRS directs that both Core Spray pumps be manually shutdown The BOP operator:
o Momentarily places both Core Spray pump control switches to the STOP position and then releases the switch.
o The Core Spray pump amber OVERRIDE INITIATED lights above both pump control switches illuminate. Then, the "A" recirc loop ruptures, resulting in the following:
RPV level and pressure lower rapidly Drywell pressure rises and stabilizes at ~ 22 psig.
Which one of the following is correct regarding the ability of Core Spray to assist in water level recovery? The Core Spray pumps will _______________ when RPV pressure lowers to less than 450 psig. A. NOT automatically restart
, but can be manually re
-started and then will inject B. automatically re
-start when RPV level lowers to less than +64 inches and inject C. automatically re

-IN reset pushbuttons are first depressed and will inject regardless of RPV level D. NOT automatically restart
, but can be manually restarted IF the CORE SPRAY INITIATION SEALED
-IN reset pushbuttons are first depressed and then will inject
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 10 Proposed Answer:
A Explanation (Optional):
A. Correct: Placing the core spray pump control switch to STOP with an auto start signal present seals out the auto start signal and lights an amber light located above the pump control switch indicating that the auto start signal has been overridden. The core spray pump may be restarted using the START position of the control switch.
B. Incorrect: The Core Spray pumps will not automatically restart. Plausible if the candidate believes that the redundant pump auto start signal of RPV level < 64" in conjunction with RPV pressure < 450 psig will restart the pump.
C. Incorrect: The Core Spray pumps will not automatically restart. Plausible if the candidate believes that the pumps will restart if the initiation reset pushbuttons are depressed. With drywell pressure above 2 psig, the initiation logic will not reset if the reset pushbuttons are depressed, therefore the core spray pumps will not restart. Although, the injection valves will open when RPV pressure lowers below 450 psig.
D. Incorrect: The core spray pump may be restarted using the START position of the control switch. Depressing the seal
-in pushbutton is not required. Plausible in that this pushbutton would reset the initiation and the pump override, but ONLY IF the initiation signals are clear. With the high drywell pressure condition the initiation cannot be reset.

D. ONLY a detector retracted w hen N OT Permitted annunciator will alarm, a rod block will prevent further rod motion
, and a half scram will occur.
Proposed Answer:
C Explanation (Optional): A. Incorrect
- withdrawing the SRM out past 90 will cause a rod withdrawal block if the SRM detectors are NOT fully inserted and SRM flux level is lower than 100 cps when the IRMs are on range 1 or 2.
B. Incorrect
- withdrawing the SRM out past 90 will cause a rod withdrawal block if the SRM detectors are NOT fully inserted and SRM flux level is lower than 100 cps when the IRMs are on range 1 or 2.
C. Correct - A rod withdrawal block will occur if the SRM detectors are NOT fully inserted and SRM flux level is lower than 100 cps when the IRMs are on range 1 or 2.

- withdrawing the SRM out past 90 will cause a rod withdrawal block if the SRM detectors are NOT fully inserted and SRM flux level is lower than 100 cps when the IRMs are on range 1 or 2. There are NO half scrams on the SRMs for normal operating conditions and even if the shorting links were installed the low reading on the SRM would NOT cause a scram.

B. remain energized due to fast transfer to the Startup Transformer.
C. de-energize and are repowered by the Standby Diesel Generators.
D. are de-energized with the Standby Diesel Generators running but NOT connected.
Proposed Answer: C Explanation (Optional):
A. Incorrect
- There NO is transfer to the Startup Transformer during this event. Plausible because the Startup Transformer also supplies the Essential Buses. Candidate may assume that the Startup Transformer will pick up the load.
B. Incorrect
- The conditions are not met for a fast transfer. The DGs will re
-energize the load centers. Plausible because the Startup Transformer also supplies the Essential Buses. Candidate may assume that the Startup Transformer will pick up the load.
C. Correct - The "Standby Transformer Feeder Breaker CB8490" breaker is the supply to the standby transformer. The loss of the Standby Transformer results in a loss of power to both vital buses. The EDGs will pick up the load centers on the bus undervoltage start signal.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 15 D. Incorrect
- Standby Transformer Lockout Relay will "Lock Out" the Standby Transformer the Essential Load Centers 1A3 and 1A4 are not locked out and will be re
-energized by the SBDGs. Plausible because the Essential Buses Supply Breakers 1A301 and 1A401 trip open deenergizing Buses 1A3 and 1A4 the candidate may assume the lockout extends to the Essential Buses or that the SBDGs will NOT automatically close in on the dead buses.

D Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 39 A. Incorrect: When Inverter output voltage lowered, the Static Transfer switch transferred the power supply to the Regulating Transformer 1Y4. When Inverter output voltage recovered, it transferred back to the Inverter. These transfers are "make before break" and would have no adverse impact on plant systems. Plausible if the candidate believes that a manual transfer back to the inverter is required. Additionally if the candidate believes it is a "break before make" transfer, both feed reg valves would lock up (see AOP 357, Loss of 120 VAC UPS)
B. Incorrect: When Inverter output voltage lowered, the Static Transfer switch transferred the power supply to the Regulating Transformer 1Y4. When Inverter output voltage recovered, it transferred back to the Inverter. Plausible if the candidate believes that a manual transfer back to the inverter is required.
C. Incorrect: The transfers are "make before break" and would have no adverse impact on plant systems. Plausible if the candidate believes the transfer is similar to that of transfer switch 1Y22 which is a "break before make" transfer.
D. Correct: When Inverter output voltage lowered, the Static Transfer switch transferred the power supply to Regulating Transformer 1Y4. When Inverter output voltage recovered, it transferred back to the Inverter. The transfers are "make before break" resulting in continuous power to 1Y23 distribution panel.

Proposed Question:
RO Question # 23 During the watch turnover it is noted that the Standby Transformer is energized and Standby Transformer Breaker (M), OCB
-8490, is closed. Later
, during a panel walkdown, it is noted that the Standby Transformer Breaker (M), OCB
-8490, RED and GREEN indicating lights are NOT lit. BOTH light bulbs are GOOD.
All other 1C08 panel indications are normal for this plant configuration
, and no annunciators were received from this event.
Which ONE of the following describes the impact of this indication?
A. Essential bus power will not transfer to the Standby Transformer when required.
B. OCB-8490 has lost control power and will ONLY respond to breaker protective breaker trips. C. OCB-8490 has lost control power and will NOT OPEN when the control switch is taken to the TRIP position D. Essential Bus Power will ONLY slow transfer to the Standby Transformer when required. Proposed Answer:
C Explanation (Optional):
A. Incorrect
- This is plausible however, this condition would not inhibit the ability of the essential busses to transfer to the Standby Transformer. The failure is in the Standby Transformer Feeder Breaker not the essential bus logic.
B. Incorrect
- This is plausible because 12 5 VDC supplies control power to the breaker. However a loss of power to the tripping circuit would block all remote and protective trips.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 47 C. Correct - The breaker indicating lights are powered from breaker control power, lost continuity in the control circuit de
-energizes indicating lights. A loss of power to the tripping circuit would block all remote and protective trips.
D. Incorrect
- This is plausible however, this condition would not have any effect on the ability of the essential busses to transfer to the Standby Transformer. The failure is in the Standby Transformer Feeder Breaker not the essential bus logic.

C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 57 A. Incorrect: The Recirc pump suction valves will also have power. Plausible in that "LPCI swing bus" 1B34A/1B44A supplies power to all LPCI and RHR valves that may have to reposition during a LPCI Loop selection. However the Recirc loop suction valves which do not reposition are also powered from 1B34A/1B44A. This would be correct if this answer if this were not the case.
B. Incorrect: "LPCI swing bus" 1B34A/1B44A supplies power to all Recirc Loop valves. The bus is normally aligned to 1A3 via 1B34. When 1A3 failed to re
-energize following the loss of off

B Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 60 A. Incorrect
- The RHR heat exchanger outlet valves (MO
-2031 [1941]) are isolation valves and NOT used for throttling flow, torus cooling is controlled by closing or opening MO-2030 [1940] A[B] HEAT EXCH BYPASS.

-2030 [MO-1940] A[B] HEAT EXCH BYPASS valve and MO
-2029 [MO-1939] A[B] HX INLET THROTTLE valve on 1C03".
B. Correct - (1) Per OI 149, Section 5.4, Open or Close MO 2030 [1940] A[B] HEAT EXCH BYPASS valve as required.
(2) Per SD 149
- The LPCI initiation signal overrides all modes of the RHR System (except shutdown cooling). The intent is to direct maximum system effort toward restoring and maintaining the reactor vessel water level, i.e., all pumps are started, all non LPCI modes secured. This would secure torus cooling and the resulting HPCI surveillance test would cause torus temperature to rise.
C. Incorrect
- The RHR heat exchanger outlet valves (MO
-2031 [1941]) are isolation valves and NOT used for throttling flow. Plausible because the RHR Heat Exchanger INLET valve is used for controlling the cooldown rate in shutdown cooling mode as stated in OI 149, "Control the cooldown rate by adjusting MO

Proposed Question:
RO Question # 30 During a control rod single notch withdrawal
, a Reactor Manual Control System timer malfunction occurs resulting in the withdraw bus remaining energized.
Which ONE of the following RMCS protective features prevents a continuous withdrawal event AND how is this accomplished?
A. When a withdrawal signal lasts greater than 2 seconds, the current rod is de
-selected and a select block is generated.
B. When the Rod Movement control switch is held in "withdraw" for greater than 2 seconds, a rod out block is generated.
C. When the Rod Movement control switch is momentarily placed in "withdraw
," any stopping of the rod sequence timer generates a select block.
D. When a single notch withdrawal signal is generated
, the rod position indication system initiates a rod block if the control rod moves beyond one notch. Proposed Answer:
A Explanation (Optional):
A. Correct - The operation of the RMCS solid state timer is monitored in the rod withdrawal mode to protect against unrequested continuous rod withdrawal should the timer fail, holding in the withdraw time interval. If the drive out time interval during notch withdrawal is actuated for a period of approximately 2 seconds (normal interval is 1.5 seconds) the timer malfunction circuit de
-energizes the rod select relays (enforces a select block). Actuation of the timer malfunction circuit energizes the amber SELECT BLOCK indicator light.
B. Incorrect
- The Rod Movement control switch may be held in "withdraw" indefinably only the time the timer is energized is monitored.
C. Incorrect
- Rod withdrawal accidents are prevented by monitoring the amount of time the r od sequence timer energizes the withdraw bus.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 63 D. Incorrect
- Rod withdrawal accidents are prevented by monitoring the amount of time the r od sequence timer energizes the withdraw bus, the RPIS does not cause this block or prevent this event.

A. (1) An Offgas premature recombination event has occurred
. (2) Shutdown the hydrogen water chemistry system.
B. (1) An Offgas premature recombination event has occurred
. (2) Start the mechanical vacuum pump and shutdown the steam jet air ejectors.
C. (1) Steam supply pressure to the Offgas Jet Compressor has lowered to 2 90 psig. (2) Start the mechanical vacuum pump to stabilize condenser vacuum.
D. (1) Steam supply pressure to the Offgas Jet Compressor has lowered to 2 90 psig. (2) Place the second set of SJAE in service in parallel with the operating SJAE.
Proposed Answer:
A Explanation (Optional):
A. Correct - In the event of Offgas premature recombination, off gas flow and recombiner temperature would lower. Action must be taken to stop the premature recombination to prevent damage to other off gas equipment and piping. To limit H2 the hydrogen water chemistry system must be secured.
B. Incorrect
- This is plausible, because with a Offgas premature recombination with power <10% the procedure directs start the mechanical vacuum pump to stabilize condenser vacuum, however in this case power level is 25%.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 71 C. Incorrect
- The low SJAE flow and erratic offgas flow indicate a H2 event NOT an offgas isolation. This distracter is plausible, because with a Offgas isolation with power <10% the procedure directs starting the mechanical vacuum pump to stabilize condenser vacuum, however in this case power level is 25%. D. Incorrect
- The low SJAE flow and erratic offgas flow indicate a H2 event NOT an offgas isolation. This distracter is plausible, because with the low off

A. Incorrect: Condition 3 will also cause a rod drift alarm. Once the timer times out a rod drift alarm will occur for that rod if an even numbered reed switch is not closed.
B. Incorrect: Condition 2 will also cause a rod drift alarm. A rod drift alarm will occur if after the timer times out an odd numbered reed switch is closed, as this may be indicative of a rod drifting.
C. Incorrect: Condition 1 will not cause a rod drift alarm. Odd numbered reed switches are normally open.

RO Question # 36 The plant is operating at 98% power with the "A" EHC Pressure Regulator in service.
A steam leak occurs on the sensing line for the "A" Pressure Regulator such that "Steam Throttle Pressure A" is slowly failing DOWNSCALE.
Assuming NO operator action is taken, which ONE of the following correctly describes the expected response of turbine throttle pressure?
Turbine throttle pressure will-A. slowly rise until the reactor scrams on either high flux or high pressure.
B. stabilize a few psig lower controlled by the "B" EHC Pressure Regulator.
C. slowly lower resulting in a reactor scram on an automatic MSIV closure.
D. stabilize a few psig higher controlled by the "B" EHC Pressure Regulator.
Proposed Answer:
D Explanation (Optional):
A. Incorrect
- As the "A" side pressure error signal goes down, the "B" pressure error signal will go up. This will eventually cause the "B" regulator to take over and control pressure
. No scram will occur.
B. Incorrect
- The "B" regulator will take over at a slightly elevated reactor and throttle pressure. C. Incorrect
- As the "A" side pressure error signal goes down, the "B" pressure error signal will go up. This will eventually cause the "B" regulator to take over and control pressure
. No scram will occur.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 75 D. Correct - As the "A" steam throttle pressure falls, the "A" side pressure error signal will go down. This will cause the CVs to begin to close. As the CVs close, reactor pressure (and hence throttle pressure) will begin to rise. This rise will be seen by the "B" regulator. So as the "A" side pressure error signal goes down, the "B" pressure error signal will go up. This will eventually cause the "B" regulator to take over at a slightly elevated reactor and throttle pressure.

, the RO is performing RIP 103.2, Increase CRD Cooling Flow and Pressure. The RO has placed both CRD pumps in service when the following annunciators alarm and remain in alarm:
1C06A (A-12) "A" CONDENSATE PUMP 1P
-8A TRIP OR MOTOR OVERLOAD 1C06A (A-13) "B" CONDENSATE PUMP 1P

? A. The CRD pumps will trip on a loss of suction pressure
- the RIP must be exited.
B. Continue in the RIP securing one CRD pump to prevent both pumps tripping on a loss of suction.
C. Continue in the RIP
- the CRD pump suction source will automatically shift to the condensate storage tanks.
D. Exit the RIP, manually shift the CRD pump suction to the condensate storage tanks
, and re-enter the RIP.
Proposed Answer:
C Explanation (Optional): A. Incorrect
- The CRD pumps will NOT trip on a loss of suction. The CST suction is always lined up to the CRD pump suction. If CV
-1497 closes the CRD pump suction will automatically shift to the CSTs. Plausible because the normal suction source is isolated on a trip of both condensate pumps.
B. Incorrect
- There is no reason to secure a CRD pump. Plausible because the normal suction source is isolated on a trip of both condensate pumps and the normal source has a higher pressure than the alternate source from the CSTs.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 77 C. Correct - The CRD pumps will NOT trip on a loss of suction. These annunciators indicate the condensate pump has tripped or is about to trip. The condensate pump breaker closed position provides an interlock to CV
-1497 through which condensate flows from the reject line to the Control Rod Drive Hydraulic System. However the CST suction is always lined up to the CRD pump suction. If CV
-1497 closes the CRD pump suction will automatically shift to the CSTs.
D. Incorrect - There is no reason to exit the RIP both CRD pumps will remain running with the CSTs as their suction. Plausible because the normal suction source is isolated on a trip of both condensate pumps.

RO Question # 39 Which ONE of the following is the highest steam dome pressure that will ensure that the reactor coolant system will remain intact at its most limiting location? A. 1250 psig B. 1335 psig C. 1380 psig D. 1590 psig Proposed Answer:
B Explanation (Optional):
A. Incorrect: Plausible in that this is the design pressure of the RPV.
B. Correct: The Tech Spec Safety Limit on reactor steam dome pressure protects the reactor coolant system against over
-pressurization. The most limiting transient location is the recirc suction piping which has a design pressure of 1150 psig. USAS, Nuclear Power Piping Code, Section B31.1, 1967 Edition (Ref. 6) permits a maximum pressure transient of 120% of design pressure or 1380 psig (120% x 1150 psig = 1380 psig). This value is adjusted to account for the added pressure due to elevation sensed at the lowest points in the reactor pressure vessel and reactor coolant system piping in order to determine the most limiting steam dome pressure. This results in a safety limit of 1335 psig steam dome pressure.
C. Incorrect: Plausible in that 1380 psig is the maximum allowed transient pressure allowed for in the recirc loop suction piping. However it does not take into account the weight of the water above the lowest section of the reactor coolant system piping in order to determine the required steam dome pressure.
D. Incorrect: Plausible in that 1590 is the maximum allowed transient pressure rating of the recirc discharge piping. However it is not the most limiting pressure within the reactor coolant system.

RO Question # 40 Following a loss of coolant accident the following conditions exist:
"A" RHR Pump is in Torus cooling at 3300 gpm "B" RHR Pump is in Torus cooling at 4700 gpm Torus pressure is 5 psig Torus water temperature is 215 °F NPSH limits are currently being exceeded for-A. Both RHR Pumps B. Neither RHR Pump C. "A" RHR pump ONLY D. "B" RHR pump ONLY Proposed Answer:
D Explanation (Optional):
A. Incorrect: The limit for "A" RHR pump is ~ 217 degrees. Plausible if the candidate sums the 2 flows and uses the "2 pumps" values for the bottom axis of the curve. If so, the limit for 8000 gpm at 5 psig torus pressure would be 215 degrees. This would be incorrect in that the two pumps are in different loops.
B. Incorrect: The "B" pump is exceeding its limit. At 4700 gpm and with a torus pressure of 5 psig, the limit is ~ 214 degrees. Plausible if the candidate again uses the "2 pump" values on the horizontal axis but considers the flow rates individually. In this case the limits for both pumps would be around 220 degrees.
C. Incorrect: The "A" RHR pump limit is ~ 217 degrees. Plausible if the candidate misinterprets the graph for the two flow rates.
D. Correct: The "B" pump is exceeding its limit. At 4700 gpm and with a torus pressure of 5 psig, the limit is ~ 214 degrees. The "A" RHR pump is < its limit of ~ 217 degrees.

Raise and control reactor water level between-A. 170 and 211 inches.
B. 186 and 195 inches.
C. 230 and 240 inches.
D. 258 and 270 inches.
Proposed Answer:
C Explanation (Optional):
A. Incorrect: AOP
-149 requires level to be raised and controlled between 230 and 240 inches. Plausible in that an EOP 1 entry condition has occurred and this is the initial control band.
B. Incorrect: AOP
-149 requires level to be raised and controlled between 230 and 240 inches. Plausible in that this range is between the low and high level alarm setpoints.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 85 C. Cor rect: Insufficient RHR flow while in SDC can result in RPV thermal stratification. To prevent thermal stratification a natural circulation flow path must be established that allows the hotter water in the reactor core to flow upwards out the steam separators into the annulus region. AOP 149, Follow
-up Action # 4 requires level to be raised and controlled betwee n 230 and 240 inches. Insufficient RHR flow while in SDC can result in RPV stratification. AOP 264, pg 8 states If RWCU System is not available OR Recirc Pumps are not available, raise RPV level to greater than (>) 214" (preferably between 230" and 240") to improve natural circulation. T.S. Bases 3.4.8 RHR Shutdown Cooling System also states "Alternate methods of reactor coolant circulation that can be used include (but are not limited to) raising reactor water level above the minimum natural circulation level (i.e., lowest turnaround point for water in the steam separator)
." D. Incorrect: AOP
-149 requires level to be raised and controlled between 230 and 240 inches. Plausible in that the higher the level the more the natural circulation. However this would flood the main steam lines.

B. Incorrect: Water displacement in the reference leg causes an increase in indicated level. Additionally, the Wide Range Yarways are to be used.
C. Correct: With the Reference Leg Back Fill System out of service, gases will accumulate in the reference legs. As gases come out of solution in the reference leg as the vessel depressurizes, water is displaced. This results in a lowering differential pressure between the reference leg and the variable leg. The lowering differential pressure results in an indicated level rise. The condensing pot then restores the level of the reference leg resulting in a return to actual level.

-Specific Proposed Question:
RO Question # 46 The plant is operating in single loop. The running Recirc Pump speed is 45%. (1) Which one of the following instruments is used to determine core flow
? AND (2) Why is this instrument used?
A. (1) 1C05 Total Core Flow recorder FR
-4635. (2) Because there is reverse flow in the idle jet pumps at this pump speed.
B. (1) 1C05 Core Plate Differential Pressure recorder PDR/FR

D. (1) 1C05 Core Plate Differential Pressure recorder PDR/FR
-4528. (2) Because there is reverse flow in the idle jet pumps at this pump speed.
Proposed Answer:
B Explanation (Optional):
A. Incorrect: At recirc pump speeds < 50% flow shifts in the idle jet pumps from reverse to forward and the Total Core Flow indication becomes inaccurate because the loop flow summers subtract the idle loop flow from the operating loop when in single loop. Plausible if the candidate believes this happens at a lower pump speed because the n there would still be reverse flow in the idle loop.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 96 B. Correct: The Total core flow indication becomes inaccurate at running pump speeds < 50% because the loop flow summers subtract the idle loop flow from the operating loop when in single loop. However at low running pump speeds the flow in the idle loop jet pumps shifts from reverse to forward flow. At speed less than 50% procedures direct that core plate delta P indications be used to determine core flow.
C. Incorrect: Core plate dp indication is used at speeds < 50%. Plausible because this indication could be converted into a core flow determination if the correlation was provided to the operator.
D. Incorrect: At this pump speed there is forward flow in the idle jet pumps. Plausible if the candidate recalls that a different indication must be used at this pump speed but does not recall why.

RO Question # 47 Primary containment pressure is rising following a large RCS break inside the primary containment. Primary containment parameters are as follows:
Drywell Pressure indication is 49 psig and slowly rising Torus pressure indication is 48 psig and slowly rising Narrow Range Torus level indication is pegged high at 16 feet IAW EOP 2, Primary Containment Control, which ONE of the following is correct regarding the vent path that should be used and why?
A. Torus vent through CV
-4301, OUTBD TORUS VENT ISOL, CV
-4309 INBD TORUS VENT BYPASS ISOL and CV
-4300 INBD TORUS VENT ISOL as required. The filtering of the SBGT system will reduce the offsite release rate.
B. Drywell vent through CV
-4303, OUTBD DRYWELL VENT ISOL, CV
-4310, INBD DW VENT BYPASS ISOL and CV
-4302, INBD DRYWELL VENT ISOL as required.
This is the ONLY vent path available due to the level in the Torus. C. The hardened vent path via CV
-4300, INBD TORUS VENT ISOL and CV
-4357, HARD PIPE VENT.
This path eliminates the potential for duct work or SBGT failure during venting which would significantly increase radioactivity levels in the reactor building.
D. Drywell vent through CV
-4303, OUTBD DRYWELL VENT ISOL, CV
-4310, INBD DW VENT BYPASS ISOL and CV
-4302, INBD DRYWELL VENT ISOL as required.
Drywell venting is always preferred while in the EOPs because it has the most immediate and direct effect on Drywell pressure.
Proposed Answer:
B DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 98 Explanation (Optional):
A. Incorrect: Torus vent paths are not allowed when torus water level is above 16 feet. Plausible in that torus venting is normally preferred du e to the scrubbing provided by the torus and this path also utilizes SBGT.
B. Correct: With torus level above 16 feet the drywell must be vented because the torus vent paths are now flooded or at least must be assumed to be flooded.
C. Incorrect: This vent path is also via the torus and Torus vent paths are not allowed when Narrow Range torus water level is above 16 feet.
D. Incorrect: If available, torus venting is preferred. The reason why the drywell vent is used in this case is because the level in the torus precludes the use of torus vent paths. Plausible in that venting the drywell will have more of an immediate effect on drywell pressure than venting the torus but is still normally less preferred than the torus venting because of the scrubbing by the Torus.

C DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 110 Explanation (Optional):
A. Incorrect: Entry into EOP 1 is Not required. EOP 3 directs that EOP 1 be entered if a pressure reduction will reduce the leak rate (steps SC 4 and 5). Given that the conditions describe a spent fuel pool leak, this is not the case. Plausible in that EOP 3 also asks whether a parameter has exceeded its Max Safe Value, and if the leaking system is a primary system then EOP 1 entry is required. Two ARMs have exceeded their Max Safe Values in that they are pegged high

Proposed Question:
RO Question # 54 The plant was operating at 15% power when an inadvertent closing of the "A" Recirc Pump discharge valve occurs. The CRS has directed the ATC operator to attempt to open the discharge valve. The BOP operator has gone to the EHC controls to adjust the EHC setpoint. Which ONE of the following applies to these conditions?
A. The simultaneous performance of these activities is permitted because the "A" Recirc Pump has tripped. B. The simultaneous performance of these activities is permitted because reactor pressure will NOT be affected.
C. The simultaneous performance of these activities is NOT permitted because of the potential for a reactor scram.
D. The simultaneous performance of these activities is NOT permitted because of the possible addition of positive reactivity.
Proposed Answer: D Explanation (Optional):
A. Incorrect: Performance of these activities is NOT permitted because of the possible addition of positive reactivity from two sources. Plausible because the candidate may assume closing the discharge valve in this condition would trip the pump. However at this power the recirc pumps will be on minimum speed and no pump trips will occur.
B. Incorrect: Performance of these activities is NOT permitted because of the possible addition of positive reactivity from two sources. Plausible because the candidate may believe that the actions taken will NOT increase reactor power, however any closure of the bypass valves will cause a positive reactivity addition.
C. Incorrect: Because the reactor mode switch is in RUN at this power level actions performed will NOT cause a reactor scram.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 112 D. Correct - Opening the recirc pump discharge valve will raise recirculation flow, while operating the EHC controls may affect bypass valve position affecting reactor pressure and also adding positive reactivity. IAW OP

K/A Justification: The DAEC generator capability curve is a function of Megavar loading and Megawatt electric loading. Main Generator voltage is not plotted on this curve. However there is a direct correlation between grid voltage and the amount of Megavar loading on the DAEC generator and therefore on generator capability curve limits.
Proposed Question:
RO Question # 57 The plant is operating at 100% power with the Main Generator in its normal full power configuration, when ITC MIDWEST notifies DAEC of potential grid instabilities over the next few hours.
Current Main Generator conditions are as follows:
640 MWe Gross 150 MVARS, lagging (out) 45 psig Hydrogen pressure One hour later grid voltage is observed to be slowly lowering.
If uncorrected, the lowering grid voltage will result in the Main Generator exceeding the Main Generator Estimated Capability Curve when-A. MVAR loading exceeds
-240 MVAR leading.
B. MVAR loading exceeds 260 MVAR lagging.
C. MVAR loading reaches 210 MVAR lagging based on exceeding the rated PF.
D. MVAR loading reaches
-100 MVAR leading based on exceeding the URAL limit.
Proposed Answer:
B Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 118 A. Incorrect: DAEC MVAR loading increases in the Lagging direction as grid voltage lowers relative to main generator terminal voltage. Plausible if the candidate is unsure of how MVAR loading varies with changes in grid voltage. (For 640 MWe and 45 psig H2, the curve is exceeded in the leading direction at
-240 MVARs)
B. Correct: As grid voltage lowers, the DAEC generator will tend to "pickup" additional reactive loading. Using the Estimated Capability Curve, the curve will be exceeded when MVAR loading increase to 260 MVAR, Lagging.
C. Incorrect: The curve will not be exceeded until MVAR loading increase to 260 MVAR, Lagging. 210 MVAR is when the .95 PF (power factor) line is exceeded for a real loading of 640 MWe. Plausible if the candidate believes the .95 PF (power factor) is a limit. This is plausible in that the generator ratings are based on a .95 PF
- see the ratings at the top of the curve.
However the individual power factors are not limits but merely define the relationship between MWe and MVAR loading.
D. Incorrect: DAEC MVAR loading increases in the Lagging direction as grid voltage lowers relative to main generator terminal voltage.
The URAL limit is only applicable when MVAR loading is in the Lead direction. Plausible if the candidate is unsure of how MVAR loading varies with changes in grid voltage.

RO Question # 58 The control room has been evacuated due to a fire in the main control room.
Regarding RHR operation via the Remote Shutdown System:
What is the reason for placing the RHR related Remote Shutdown System transfer switches in the EMER position following a control room evacuation?
These switches
- A. install separate auto isolation circuits to ensure that fire damage will NOT prevent an automatic isolation on low vessel level.
B. install separate auto initiation circuits to ensure that fire damage will NOT prevent an automatic LPCI injection on L ow-L ow-Low vessel level.
C. ensure that fire induced circuit faults associated with normal control circuits are isolated and will NOT prevent RHR operation from the Remote Shutdown panels.
D. ensure that fire induced faults in control power circuits will NOT prevent RHR operation by transferring RHR pump and valve power supplies to alternate power supplies.
Proposed Answer:
C Explanation (Optional):
A. Incorrect: The low level isolation for SDC is bypassed when the transfer switches are in EMER. B. Incorrect: LPCI initiation signals and LPCI valve logics are bypassed when the transfer switches are in EMER.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 120 C. Correct: The design basis scenario for the adequacy of the Remote Shutdown Panel System assumes that normal control circuits may either short circuit or open circuit due to the fire. Therefore, to take credit for having equipment available, fire damaged circuits must be isolated and replaced by non
-damaged control circuits. This is the function of the transfer switches.
D. Incorrect:
Power to the pumps and valves is not transferred. Plausible in that the "yellow" transfer switches will transfer components to the emergency fuses in case a normal control circuit has blown due to fire damage. However the power supply remains the same.

RO Question # 59 During ATWS conditions Boron was injected and RPV level intentionally lowered to reduce reactor power.
RPV level is now being controlled between
-25 inches and +15 inches.
Based on the above:
(1) When can RPV level FIRST be raised to the normal control band of +170 inches to +211 inches AND (2) Why is water level raised at this time?
A. (1) W hen the Hot Shutdown Boron Weight is injected (2) So that a controlled plant cooldown can be commenced without challenging adequate core cooling.
B. (1) W hen the Cold Shutdown Boron Weight is injected (2) So that a controlled plant cooldown can be commenced without challenging adequate core cooling.
C. (1) W hen the Hot Shutdown Boron Weight is injected (2) To mix the Boron that has accumulated below the core plate with the water in the core by increasing natural circulation flow.
D. (1) W hen the Cold Shutdown Boron Weight is injected (2) To mix the Boron that has accumulated below the core plate with the water in the core by increasing natural circulation flow.
Proposed Answer:
C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 122 A. Incorrect: Level is raised to mix the boron that may have accumulated in the lower plenum. Plausible in that a plant cooldown is contingent upon how much boron has been injected.
B. Incorrect: Level is raised to mix the boron that may have accumulated in the lower plenum. Additionally level is raised as soon as the hot shutdown boron weight is injected. C. Correct: IAW with the ATWS EOP, steps L
-7 and L-8, level is raised when the Hot Shutdown Boron Weight is injected. When level was lowered to below TAF, little if any natural circulation was occurring.
The boron that was being injecting was accumulating in the lower plenum due to the low flow conditions. Once the Hot Shutdown Boron Weight has been injected it is necessary to raise level and re
-establish natural circulation in order to mix the boron.
D. Incorrect: IAW with the ATWS EOP, steps L
-7 and L-8, level is raised when the Hot Shutdown Boron Weight is injected. Plausible in that other EOP actions are contingent on the Cold Shutdown Boron Weight Being injected.

RO Question # 60 With the plant operating at 100% power, CV-4416, "B" OUTBOARD MSIV and CV
-4419, "C" OUTBOARD MSIV fail SHUT.
Which ONE of the following will be the impact of this failure?
This condition will result in-A. NO automatic actions
. B. a half scram initiated by the "B" and "C" MSIV position
. C. a full scram initiated by reactor pressure.
D. a full scram initiated by the "B" and "C" MSIV position.
Proposed Answer:
C Explanation (Optional):
A. Incorrect:
Plausible; would be true for an initial low power condition. With Mode Switch in STARTUP, no automatic actions occur. 75% is the normal power limitation with 3 Main Steam Lines.
B. Incorrect: Plausible; would be true for A and B, C and D, A and C, or B and D with a lower initial power. B and C MSIV do NOT cause a Half Scram based on valve positions.
C. Correct: Closure of one MSIV at full power raises reactor pressure to the alarm point, and power >120%. (Steam flow in the remaining lines also rises to near the MSL Hi Flow Group 1 isolation setpoint.). The sudden closure described causes transient power and pressure above the scram setpoints. This transient results in a full scram.
It is required to enter IPOI
-5 and place the Reactor Mode Switch in SHUTDOWN.
D. Incorrect: Plausible because closure of the two valves does cause a scram and MSIV position does cause a scram, however B and C MSIV do NOT cause a Full Scram based on valve positions, they would cause a half scram

Level RO SRO Tier # 1 Group # 1 K/A # 295015 AK3.01 Importance Rating 3.4 Knowledge of the reasons for the following responses as they apply to INCOMPLETE SCRAM: Bypassing rod insertion blocks Proposed Question:
RO Question # 61 Following a reactor scram, 6 control rods failed to fully insert.
The CRS has authorized the use of RIP 103.3, MANUALLY DRIVE CONTROL RODS, to complete the control rod insertion.
Which ONE of the following actions is directed by RIP 103.3 in order to prevent control rod blocks from interfering with manually inserting the rods?
A. Bypass the RWM to prevent any RWM insert blocks from interfering with rod insertion.
B. Bypass the RWM to prevent any RPIS Inoperative select blocks from interfering with rod insertion.
C. Bypass the SRM closest to the control rods being inserted to prevent SRM associated rod blocks
. D. Insert rods using ONLY the EMER ROD IN/NOTCH OVERRIDE switch because this will bypass all insert blocks.
Proposed Answer:
A Explanation (Optional):
A. Correct: RIP 103.3, step 3, directs that the RWM be bypassed. This is to prevent any RWM insert blocks from preventing rod insertion. Following a scram multiple insert errors would be indicated when one of the problem rods was selected for insertion resulting in a RWM insert block.
B. Incorrect: The RWM is bypassed in order to prevent insert blocks. An RPIS Inop condition would still result in a select block preventing rod insertion regardless of the position of the RWM bypass switch.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 126 C. Incorrect: Bypassing an SRM will not prevent a RWM insert block. Plausible in that SRM reading near the control rods will change, however with the SRMs inserted lowering counts will NOT cause a rod block.
D. Incorrect: The EMER ROD IN/NOTCH OVERRIDE switch will not prevent a RWM insert block. Plausible in that use of this switch is directed in RIP 103.3 and it also acts directly on the directional control valves of the HCUs, bypassing the timer circuits.

(1) (2) Emergency depressurization is currently required D. (1) (2) Before offsite release rates exceed that level requiring a General Emergency Proposed Answer:
B Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 130 A. Incorrect: An entry condition to EOP 4 was exceeded when offsite release rates exceeded that requiring an Alert. EOP 4 requires an emergency depressurization be performed before release rates exceed that requiring a General Emergency. Although EOP 3 entry conditions have also been exceeded there are no conditions currently requiring an ED since the max safe temperature is limited to one area.
B. Correct: A blowout panel in the steam tunnel will vent the steam tunnel to the turbine building when pressure in the steam tunnel exceeds 7 inches of water. An entry condition to EOP 4 was exceeded when offsite release rates exceeded that requiring an Alert. EOP 4 requires an emergency depressurization be performed before release rates exceed that requiring a General Emergency.
C. Incorrect: A blowout panel in the steam tunnel will vent the steam tunnel to the turbine building when pressure in the steam tunnel exceeds 7 inches of water. Plausible if the candidate does not recognize that the blowout panel will vent the steam tunnel as this would then be the correct flow path. Also there are no conditions currently requiring an ED. D.

RO Question # 65 The plant is operating at 100% power with the Drywell pneumatic system aligned for normal full power operation.
Then, an inadvertent Group 3 isolation occurs.
Which ONE of the following is correct regarding the impact o f the isolation on the Drywell pneumatics and Drywell components?
A. The Drywell pneumatic supply line will isolate. Local accumulators inside the Drywell will provide for 5 actuations of the inboard MSIVs.
B. The Drywell pneumatic supply line will isolate. Local accumulators inside the Drywell will provide for 5 actuations of the ADS valve s until the isolation can be corrected.
C. The Drywell N2 compressor will trip when Compressor Suction Isolation Valves, CV-4378A & CV
-4378B close. Emergency N2 Backup Supply Valve CV
-4377 will open to maintain the pneumatic supply to the Drywell. D. The Drywell N2 compressor will trip when Compressor Suction Isolation Valves, CV-4378A & CV
-4378B close. Nitrogen Accumulator 1T128 will maintain the pneumatic supply to the Drywell until the isolation can be corrected.
Proposed Answer:
B Explanation (Optional):
A. Incorrect: The MSIVs are not assured of remaining open for this period of time. Plausible in that there are accumulators associated with the MSIVs. However the accumulator volume is adequate to provide full stroking of the valve, (NOT five) for only one half cycle (open to close) when supply gas to the accumulator has failed.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 134 B. Correct: In addition to the compressor suction valves, compressor isolation valve, CV-4371A also closes, isolating the pneumatic supply line. The accumulator on each ADS valve provides pneumatic pressure for valve actuation. The design pneumatic supply pressure requirements for the accumulator are such that following a failure of the pneumatic supply to the accumulator; each ADS valve can be actuated at least 5 times up to 100 days following a LOCA.
C. Incorrect: In addition to the compressor suction valves, compressor isolation valve, CV-4371A also closes, isolating the pneumatic supply line. Although Emergency N2 Backup Supply Valve CV
-4377 will open as accumulator pressure lowers, the drywell will remain isolate
- d. D. Incorrect: In addition to the compressor suction valves, compressor isolation valve, CV-4371A also closes, isolating the pneumatic supply line. Accumulator 1T128 is upstream of these isolation valves and will have no bearing on maintaining drywell pneumatics.

Proposed Question:
RO Question # 67 A control room operator is running a Standby Diesel Generator Surveillance Test Procedure (STP). After the Operator completes each step of the surveillance, the Operator places their initials beside the step.
While conducting the test
, an unexpected alarm is received in the Control Room. The Operator acknowledges and announces the alarm, ensures that the Diesel Generator is in a stable condition, flags the current step in the STP, lays the STP to the side, and pulls out the Annunciator Response Procedure (ARP) for the alarm.
The operator reviews the steps in the ARP, sets it down, and without any further reference to the ARP , begins taking the stated actions.
The Operator then gets permission from shift supervision and returns to the STP flagged step, performs a Job Site Review, and continues on with the STP performance.
Which ONE of the following is correct regarding the operator's compliance with the requirements for procedural adherence?
A. NO, the operator has NOT complied. STPs cannot be suspended in order to take other actions. B. YES, the operator has complied. STPs are continuous use procedures
, and ARPs are reference use procedures.
C. NO, the operator has NOT complied. The ARP is a reference use procedure and must be either place kept
, or periodically reviewed and reviewed upon completion.
D. YES, the operator has complied. Operators are allowed to take any actions deemed necessary to respond to the alarm even if it conflicts with an approved procedure (STP).

- Reference use procedures require place keeping and reviewing the actions taken. Plausible because the candidate may not realize the actions required for a reference use procedure and literally treat the procedure as a reference.
C. Correct - The ARP is a "Reference Use" procedure, requiring the CRO to complete each step in the sequence specified unless the procedure specifically allows otherwise. Then mark off steps when completed and review the procedure upon completion to verify required actions were completed.
D. Incorrect - Reference use procedures require place keeping and reviewing the actions taken. Plausible because the candidate may not realize the actions required for a reference use procedure and literally treat the procedure as a reference.

Which ONE of the following is the MAXIMUM power level permitted for this Drywell entry
?
Reactor power must be -
A. below range 1 on the IRMs B. below the point of adding heat, approximately 2% power C. stable and below approximately 7% power D. stable and below 30% power Proposed Answer:
C Explanation (Optional):
A. Incorrect
- Reactor power must be below Approximately 7% power. This is plausible if the candidate assumes that the reactor must be almost subcritical to enter the drywell.
B. I ncorrect - Reactor power must be below Approximately 7% power. This is plausible if The candidate assumes the limit is based on drywell temperature conditions as well as reactor power and radiation levels.
C. Correct - To protect against the radiological hazards of an operating reactor a drywell entry can be made with reactor power stable and <30 on IRM Range 10, (~7%).
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 146 D. Incorrect
- Reactor power must be below Approximately 7% power unless permission is granted to exceed 7% by the Plant Manager.
In this question the stem states "The Plant Manager has directed that all requirements of IPOI 7, Special Operations, are to be adhered to.
" Therefore , the 7% limit applies. Plausible be because the actual limit is <30 on range 10 of the IRMs (~ 7% powe r) and that IPOI 2 raises power level up to 35%. Technical Reference(s):

Proposed Answer:
C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 148 A. Incorrect
- Demanding an OD3 would determine control rod position after a Scram and before the Scram reset, some control rods will go to an overtravel condition. This is a position beyond the full
-in "00" indication. A control rod printout will display these overtravel positions as "-99". This display cannot be distinguished from a control rod in any other mid

B. Incorrect
- Tripping the EPA breakers will remove power from the RPS buses and cause unnecessary isolations and is NOT used in AOP 915. Plausible because this is a quick way to scram the reactor from outside the control room.
C. Correct - IAW AOP 915; Open the door of Panel 1Y30 with a screwdriver and turn off the circuit breakers on for Power Range Neutron Monitoring System A and B. Then locally verify all scram valves open. Use Attachment 4 (CRD HCU Location /Scram Valve Checklist) for check o ff. D. Incorrect

Proposed Question:
RO Question # 75 A plant startup is in progress following a refueling outage. A Control Room Operator is performing the initial startup of the Reactor Building Closed Cooling Water (RBCCW) system using OI 414, Reactor Building Closed Cooling Water. The operator notices the step to start the "A" RBCCW pump is incorrect as shown below:
Description Handswitch A TBCCW PUMP 1P
-81A HS-4829 B RBCCW PUMP 1P
-81B HS-483 3 C RBCCW PUMP 1P
-81C HS-4837 Which ONE of the following statements is correct regarding the error in the procedure?
A. The RO must exit the procedure, place all equipment in a safe condition, and then discuss the error with the OSM/CRS.
Until th e procedure is revised
, the "A" RBCCW pump may NOT be started
. B. The RO may make a field change to the procedure and start the "A" RBCCW pump. When the procedure is completed
, the RO must notify the OSM/CRS of the field change for further corrective action. C. The startup of the RBCCW system must be stopped and the error brought to the attention of the OSM/CRS. The OSM/CRS authorizes an editorial change to the procedure to permit starting the "A" RBCCW pump.
D. The startup of the RBCCW system may continue the RO must obtain concurrence from another licensed operator prior to completing the step. The editorial change must be discussed with the OSM/CRS before the end of the shift.
Proposed Answer:
C Explanation (Optional):
A. Incorrect
- Typical editorial correction(s) are processed administratively and typically 'in the field'. As such, they do not require formal reviews (i.e. no PCR or Temp Change and none of the typical forms or screenings required of a permanent change. Therefore there is NO need to wait to start the pump. Plausible because most procedure changes do require submitting a procedure change request or CR which would could stop completing the procedure as written.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 154 B. Incorrect
- The work must be stopped (in this case starting the "A" RBCCW pump) and the error brought to the attention of the OSM/CRS. The OSM/CRS must authorize starting the "A" RBCCW pump. Plausible because the RO would proceed with the procedure AFTER making a field change authorized by the CRS/OSM.
C. Correct - The work must be stopped (in this case starting the "A" RBCCW pump). IAW AD-AA-100-1006, For obvious minor typographical errors, minor discrepancies in nomenclature or discrepancies involving equivalence (i.e. handswitch in STOP versus OFF, START versus HAND or MAN, etc), the OSM/CRS may, after review, allow the procedure to continue. Since the pump identification number (1P
-81A ) and switch identification number (HS
-4829) are correct this is a typographical error. Based on this the procedure can be performed as written. Typical editorial correction(s) are processed administratively and typically 'in the field'. As such, they do not require formal reviews (i.e. no PCR or Temp Change and none of the typical forms or screenings required of a permanent change.
D. Incorrect
- The work must be stopped (in this case starting the "A" RBCCW pump) and the error brought to the attention of the OSM/CRS. The OSM/CRS must authorize starting the "A" RBCCW pump, NOT another licensed operator which may be an RO.

SRO Question # 77 An Emergency Depressurization is in progress following high drywell air temperature conditions. Current plant conditions are as follows:
All Control Rods are fully inserted Four SRVs were originally opened, but two have just failed closed No other SRVs can be open ed Reactor pressure is 75 psig, lowering slowly Torus pressure is 1 0 psig and lowering slowly Drywell air temperature is 325°F, rising slowly Core Spray is injecting at rated flow RHR injection is NOT available RPV level indicator response during the depressurization was as follows:
o Floodup Range indication pegged low but has been rising steadily and is now +190 inches and steady o Wide Range Yarway indication lowered steadily to +15 inches but then began rising steadily and is now +22 inches and steady o Fuel Zone indication lowered steadily to
-40 inches but then began oscillating o Fuel Zone indication is now +10 inches and continuing to rise slowly.
o Water level oscillations have stopped.
Using the information provided:
(1) What is RPV Water Level?
AND (2) What action is required for RPV pressure control? A. (1) +10 inches (2) Continue depressurizing with the 2 SRVs ONLY until the plant is in cold shutdown B. (1) +22 inches (2) Alternate Depressurization Systems of Table 8 of ED
- Emergency Depressurization must be aligned to complete the depressurization.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 159 C. (1) -13 inches (2) Continue depressurizing with the 2 SRVs ONLY until the plant is in cold shutdown D. (1) -13 inches (2) Alternate Depressurization Systems of Table 8 of ED
- Emergency Depressurization must be aligned to complete the depressurization.
Proposed Answer: D Explanation (Optional):
A. Incorrect: RPV level is
-13 inches. RPV parameters are above the Saturation Curve of graph 1. Additionally indication was received of boiling as the vessel depressurized. Per Caution 1, if boiling is suspected, 23 inches is to be subtracted from the fuel zone indication. Plausible if the candidate discounts the fuel zone indication due to the oscillations and relies on the Wide Range indication or the candidate believes that the Fuel Zone level of +10 inches is accurate because the level oscillations have stopped. If 2 of the 4 SRVs have gone closed prior to RPV pressure being within 50 psig of the torus pressure the crew must continue the depressurization with alternate depressurization systems. Plausible if the candidate assumes that the two SRVs will continue the emergency depressurization.
B. Incorrect: RPV level is
-13 inches. Plausible if the candidate discounts the fuel zone indication due to the oscillations and relies on the Wide Range indication or the candidate believes that the Fuel Zone level of +10 inches is accurate because the level oscillations have stopped. However this instrument cannot be used because indication of boiling has occurred.
C. Incorrect: RPV parameters are above the Saturation Curve of graph 1 and indications of reference leg boiling has occurred. Per Caution 1, if boiling is suspected, 23 inches is to be subtracted from the fuel zone indication. This would result in a level of
-13 inches. However if 2 of the 4 SRVs have gone closed prior to RPV pressure being within 50 psig of the torus pressure the crew must continue the depressurization with alternate blowdown systems. Plausible if the candidate assumes that the two SRVs will continue the emergency depressurization.
D. Correct: RPV parameters are above the Saturation Curve of graph 1 and indications of reference leg boiling has occurred. Per Caution 1, if boiling is suspected, 23 inches is to be subtracted from the fuel zone indication. This would result in a level of -13 inches. Because 2 of the 4 SRVs have gone closed, and no other SRVs will open; prior to RPV pressure being within 50 psig of the torus pressure, the crew must continue the depressurization with alternate depressurization systems.

Proposed Answer:
A DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 162 Explanation (Optional):
A. Correct - IAW AOP 915, if reactor water level can be controlled above 119.5 inches reactor pressure is maintained and the cooldown rate controlled using SRVs. A NOTE that appears in AOP 015 states "While it is desirable to limit cooldown rate to <80° F/Hr, cooldown rate cannot be controlled during Emergency Depressurization or HPCI/RCIC injection. The Technical Specification cooldown rate limit of 100° F in any 1 hr. period applies to normal plant cooldown only." Because there is NO reason stated for Emergency Depressurization or HPCI/RCIC injection the desirable cooldown rate is <80° F/Hr. B. Incorrect
- A NOTE that appears in AOP 015 states "While it is desirable to limit cooldown rate to <80° F/Hr, cooldown rate cannot be controlled during Emergency Depressurization or HPCI/RCIC injection. The Technical Specification cooldown rate limit of 100° F in any 1 hr. period applies to normal plant cooldown only." Because there is NO reason stated for Emergency Depressurization or HPCI/RCIC injection the desirable cooldown rate is <80° F/Hr.
C. Incorrect
- Plausible because RCIC is cited in AOP 915, Shutdown Outside the Control Room. However, RCIC is only used for RPV water makeup and its specific operation is directed in AOP 915, NOT OI 150.
D. Incorrect
- Plausible because RCIC is cited in AOP 915, Shutdown Outside the Control Room. However, RCIC is only used for RPV water makeup and its specific operation is directed in AOP 915, NOT OI 150.

Proposed Question:
SRO Question # 80 An ATWS is in progress. The following conditions exist:
Bypass valves failed to open and cannot be opened Reactor pressure is being maintained 800
-1000 psig and 2 SRVs are open Torus water temperature is 120°F Torus water level is 12.8 feet Control rod insertion has NOT been established SBLC failed to inject and cannot be started No alternate Boron injection system is injecting When RPV level reaches
-10 inches, direction is given to re
-establish injection and maintain indicated level
-25 to +1 5 inches. With RPV water level at
-15 inches, RPV injection is re
-established. Twenty (20) seconds later RPV water level is +1 7 inches and reactor power is 6%
.
Which ONE of the following is the correct action in response to this transient?
A. Terminate and prevent injection again
. B. Perform a RPV Blowdown per EOP
-ED. C. Direct a new level control band of
-10 to +15 inches. D. Reduce the injection rate until reactor power falls below 5%.
Proposed Answer:
A Explanation (Optional):
A. Correct - Level rise outside the assigned level band (above +15) will cause reactor power to increase and exceed 5%. Override conditions are met ( Power above 5%, Level above +15 inches, Torus water temp above 110°F, and an SRV is open) this requires returning to terminate and prevent injection until reactor power lowers below 5% or level is at +15 inches or the SRVs remain closed.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 167 B. Incorrect
- There is initially a 28°F margin to HCTL (120°F is the lower line on the HCTL graph), and rise in suppression pool temperature will not require RPV Blowdown at this time. Torus water level is 1 foot below the level that would require RPV Blowdown.
C. Incorrect
- Level rise has caused reactor power to increase and exceed 5%. This new level band could permit power to remain at 6%. Override conditions are met to terminate and prevent injection until reactor power lowers below 5% or level is at +15 inches or the SRVs remain closed.
D. Incorrect
- Override conditions are met to terminate and prevent injection again Technical Reference(s):

Proposed Question:
SRO Question
- 81 The plant is operating at 78% power with the Turbine Generator on line when DAEC switchyard voltage slowly lowers from 100% to 90% of normal voltages over a 5 minute time period
. Which of the following procedures are required to be entered as voltage lowers? A. Enter AOP 30 4 , Grid Instability; N O other procedures are required during this event. B. Enter AOP 301, Loss of Essential Electrical Power
- NO other procedures are required during this event.
C. Enter AOP 30 4 , Grid Instability, AOP 301, Loss of Essential Electrical Power, IPOI 5 Reactor Scram
. D. Enter AOP 30 4 , Grid Instability, AOP 301, Loss of Essential Electrical Power, and IPOI 5, Reactor Scram. There is NO need to enter EOPs at this time.
Proposed Answer:
C Explanation (Optional):
A. Incorrect
- Plausible because AOP 304 is entered for these conditions, however with voltage this low the vital buses will trip resulting in a reactor scram as the RPS buses are de-energized.
B. Incorrect
- Entry condition s are met for AOP 304, which is only exited when the essential buses 1A3 and 1A4 trip when the voltages lowers to 91.3%. When the essential buses trip it is an entry condition for AOP 301. Plausible if the candidate fails to recognize the degraded grid conditions and focuses on the loss of essential Bus power.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 169 C. Correct - Entry conditions are met for AOP 304, which is only exited when the essential buses 1A3 and 1A 4 trip when the voltages lowers to 91.3%. When the essential buses trip it is an entry condition for AOP 301. A reactor scram will occur because of a loss of power to the RPS buses when the vital buses de
-energize so the crew must enter IPOI 5. The resultant reactor SCRAM will cause RPV level to lower below the entry requirements for EOP
-1 necessitating its entry.
D. Incorrect - AOP 304 is entered on the low voltage condition but is exited when the loss of the essential buses occurs and the crew must enter AOP 301. The reactor scrams because of a loss of power to the RPS buses when the vital buses de
-energize so the crew must enter IPOI 5. The non-essential buses will remain energized and the essential buses are powered from the SBDGs so no loss of feedwater occurs and there is no need to enter an EOP at this time.
Plausible if the candidate determines that reactor water level will be maintained through the use of Condensate and Feedwater since the non
-essential busses remain energized throughout this event. The candidate may incorrectly determine that EOP
-1 has no entry conditions on a loss of electrical power. However, the SCRAM from 78% power would result in exceeding the Low
-Level trip setpoint requiring entry to EOP

Level RO SRO Tier # 1 Group # 1 K/A # 295006 2.4.35 Importance Rating 4.0 Emergency Procedures / Plan: Knowledge of local auxiliary operator tasks during emergency and the resultant operational effects. SCRAM SRO Level Justification: IPOI 5, Reactor Scram states that If all control rods are not fully inserted, EOP Support Rod Insertion Procedures may be used as authorized by the CRS. The SRO must know the operational effects of the local actions associated with each procedure in order to select the correct procedure.
Proposed Question:
SRO Question # 82 The plant was at 10% power starting up, when a manual scram was inserted following an equipment failure. Conditions are as follows:
Eight control rods failed to insert The Blue Scram lights are on for ALL control rods All scram signals have been cleared
, but the scram CANNOT be reset The RO reports that there is insufficient cooling water pressure to drift the rods after fully opening the CRD Flow Control Valve Which ONE of the following procedures should you direct be performed
? A. RIP 103.1, Individual Scram Test Switches
. B. RIP 103.3, Manually Drive Control Rods
. C. RIP 101.3, Vent Scram Air Header
. D. RIP 101.2, RPS Fuse Removal. Proposed Answer:
B Explanation (Optional):
A. Incorrect: The scram signal has already caused the scram inlets and outlets for the 8 rods to open as evidenced by the blue scram lights being illuminated. Plausible if the candidate does not understand what will cause the blue scram light to turn on.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 171 B. Correct: RIP 103.3 directs that if the scram cannot be reset and there are difficulties inserting the rods with CRD hydraulic pressure then an AO must be sent into the plant to close the CRD Charging Water Isolation Valve. This will shut off flow to the accumulators resulting in an increase in CRD drive pressure.
C. Incorrect: The air header is already vented. The scram inlets and outlets for the 8 rods have repositioned as evidenced by the blue scram lights being illuminated. Plausible if the candidate does not understand what will cause the blue scram light to turn on.
D. Incorrect: Pulling the fuses will de
-energize the scram trip logic. This would be an appropriate action for an electrical ATWS. This action would prevent the RPS from resetting.

Secure Drywell sprays and terminate injection from condensate and inject with low pressure ECCS D. Terminate injection from condensate and inject with low pressure ECCS while continuing Drywell sprays Proposed Answer:
C Explanation (Optional):
A. Incorrect: Emergency Depressurization is not required at this time. Plausible in that Torus parameters are close to exceeding the PSP curve. The required action to secure injection from condensate and shift injection to the low pressure ECCS will terminate the torus level rise and prevent exceeding the PSP curve.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 173 B. Incorrect: Emergency Depressurization is not required at this time.
C. Correct: When Torus level cannot be maintained below 13.5 feet, step T/L
-11 requires that the drywell sprays be secured. This action is required because the torus to drywell vacuum breakers are covered and continued spraying could result in exceeding the negative design pressure rating of the containment. Additionally, step T/L 12 requires that injection from sources external to the primary containment be terminated if not required for core cooling. Since RPV pressure is within the capacity of low pressure ECCS, RPV level control should be shifted to LP ECCS to stop the torus level rise.
D. Incorrect: Step T/L
-11 requires that the drywell sprays be secured.

Proposed Answer:
C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 175 A. Incorrect: Once the Core Spray pump tripped, adequate core cooling via spray cooling was lost. EOP 1 step RC/L
-12 directs that injection be maximized with all available injection systems in an attempt to restore level to above
-25 inches. Only after this attempt has been proven unsuccessful is SAG entry required. Additionally, once SAG entry is required, all EOPs are exited.
B. Incorrect: Once the Core Spray pump tripped, adequate core cooling via spray cooling was lost. EOP 1 step RC/L
-12 directs that injection be maximized with all available injection systems in an attempt to restore level to above
-25 inches. Only after this attempt has proven unsuccessful is SAG entry required.
C. Correct: Once the Core Spray pump tripped, adequate core cooling via spray cooling was lost. EOP 1 step RC/L
-12 directs that injection be maximized with all available injection systems in an attempt to restore level to above
-25 inches. Additionally, EOP 2 directs that only those pumps not required for core cooling be utilized for containment sprays. Since torus pressure was 31 psig, it will begin to rise once sprays are secured. The only available action then is to vent the containment to maintain pressure less than the limit of 53 psig.
D. Incorrect: Once the Core Spray pump tripped, adequate core cooling via spray cooling was lost. EOP 1 step RC/L

SRO Question # 85 A LOCA is in progress with the following conditions:
RPV water level is being maintained at +180 inches with Condensate and Feedwater Both recirc pumps are tripped Containment sprays are currently unavailable Drywell temperature reaches 280°F and continues to rise slowly.
Ten (10) minutes later Drywell temperature and pressure are now reported to be 290°F and 12 psig, both slowly rising and within the bounds of the Drywell Spray Initiation Limit.
Which ONE of the following describes the actions that are to be taken to control primary containment temperature if Drywell sprays become available per EOP 2? A. Enter ED-Emergency Depressurization
- after the reactor is depressurized Drywell sprays are NOT required. B. Enter ED-Emergency Depressurization
, spray the Drywell to lower Drywell temperature. If Drywell temperature lowers below 280
°F, exit E D-Emergency Depressurization and re-enter EOP-1 pressure control.
C. IAW EOP 2, Primary Containment Control, spray the Drywell to lower Drywell temperature and pressure. If Drywell temperature and pressure do NOT lower, exit EOP 1 Pressure Control and enter ED-Emergency Depressurization D. IAW EOP 2, Primary Containment Control, spray the Drywell to lower Drywell temperature and pressure. Exit EOP 1 Pressure Control and enter ED
-Emergency Depressurization regardless of Drywell temperature response. Proposed Answer:
C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 177 A. Incorrect: An immediate Emergency Depressurization is not required. Plausible in that temperature is above the value associated with the Emergency Depressurization step. Additionally the decision not to spray the drywell is also plausible if the candidate does not understand the meaning of a "Before" step. The direction to spray the drywell is "Before" the drywell temperature reaches 280
°F. B. Incorrect: An immediate Emergency Depressurization is not required. Plausible in that temperature is above the value associated with the RPV ED step.
C. Correct: Drywell and temperature and pressure are within the DSIL curve. Although drywell temperature is above the value requiring a blow down, the associated step directs that when temperature "cannot be restored and maintained" below 280
°F, only then is a blow down performed. As discussed in the EOP bases, the step allows the operator to attempt to restore the drywell temperature below 280°F. Since not all the steps have been performed to prevent the blow down the action of initiating drywell sprays should first be attempted. If after attempting drywell sprays, drywell temperature cannot be restored below 280°F, then Emergency Depressurization is required. D. Incorrect: Emergency Depressurization is not immediately required after spraying the drywell. Plausible in that temperature is above the value associated with the Emergency Depressurization step.

DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 179 Proposed Answer:
C Explanation (Optional):
A. Incorrect: APRM "E" is inoperable due to having only one operable LPRM at the "A" level. IAW OI 878.4 to be considered operable, APRM E must have at least 13 LPRM inputs. Each APRM must have at least 2 LPRM inputs per level. Plausible in that the APRM does satisfy the requirement for the overall number of LPRMs in that 13 of the 20 assigned LPRMs is operable. If the candidate believes that the APRM is operable then the required action would be to bypass the LPRM and adjust gains as required.
B. Incorrect: The APRM output would lower. Plausible in that, unlike the Rod Block Monitor, there are no input trip units that monitor the status of the LPRMs inputting into the APRM. Therefore the output of the downscale LPRM would be included into the overall average causing the APRM output to lower. Additionally the APRM would be inoperable as described in explanation "A".
C. Correct: The output of the APRM would lower as described in explanation "B". IAW OI 878.4 to be considered operable, APRM E must have at least 13 LPRM inputs.
Each APRM must have at least 2 LPRM inputs per level. Therefore APRM "E" is inoperable. With APRM "A" also inoperable only one APRM is operable for RPS "A". TS LCO3.3.1.1, RPS Instrumentation and associated table requires a minimum of 2. Therefore Condition "A" of the LCO is not satisfied and the required action is to place the channel or trip system in trip within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Proposed Question:
SRO Question # 88 RPV Flooding is being executed following a complete loss of RPV level indication.
Plant conditions are as follows
- Many control rods are still fully withdrawn The switches for four (4) ADS valves have been placed in OPEN Reactor pressure is 7 00 psig and lowering Given these conditions what action is required?
Wait until RPV pressure is below the Minimum Steam Cooling Pressure (MSCP), then- A. slowly raise injection to maintain at least one SRV open and reactor pressure above
, but as close to the MSCP as possible
. B. slowly raise injection to the RPV to maintain all four SRVs open and reactor pressure below , but as close to the MSCP as possible
. C. maximize injection to the RPV to maintain all four SRVs open with reactor pressure above , but as close to the MSCP as possible. D. maximize injection to the RPV to maintain at least one SRV open with reactor pressure below , but as close to the MSCP as possible.
Proposed Answer:
A Explanation (Optional):
A. Correct - When RPV pressure is below the Minimum Steam Cooling Pressure (MSCP) injection flow must be slowly raised. With 4 ADS valves opened, the Minimum Steam Cooling Pressure is 160 psig. With one SRV open the MSCP is 680 psig. As long as RPV pressure is maintained above the MSCP for the number of SRVs open the core will be cooled by submergence or steam cooling.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 184 B. Incorrect
- When RPV pressure drops below the Minimum Steam Cooling Pressure, steam flow may no longer be sufficient to provide adequate core cooling. All four SRVs are NOT required to be open.
C. Incorrect
- If injection is maximized RPV water level, reactor power, and RPV pressure will rise. Injection must be throttled to reduce pressure and the subsequent power increase. Injection must NOT be maximized and all injection must be from ATWS preferred flooding systems. All four SRVs are NOT required to be open.
D. Incorrect - If injection is increased, RPV water level, reactor power, and RPV pressure will rise. Injection must be throttled to reduce pressure and the subsequent power increase. Injection must NOT be maximized and all injection must be from ATWS preferred flooding systems.
As long as RPV pressure is maintained above MSCP the core will be cooled by submergence or steam cooling.

Proposed Question:
SRO Question # 89 During operation at 100% power an operator reports the heat tracing on the suction side of the Standby Liquid Control (SBLC) pumps is damaged and inoperable. The following conditions exist: SBLC Tank Concentration is 14%.
SBLC Tank Volume 3200 gallons.
Reactor Building Ambient Temperature at SBLC Pumps is 72°F.
Which ONE of the following describes the condition of the SBLC system per Technical Specifications?
A. OPERABLE as long as Reactor Building Temperature remains at its current value which is based on preventing Boron from precipitating out of solution inside system components
. B. INOPERABLE because the Boron Solution Concentration is below the minimum allowable. A 7 day LCO is required, which is based on injecting 780 ppm of Boron solution into the reactor core
. C. INOPERABLE because the Boron Solution Concentration is below the minimum allowable. An 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> LCO is required, which is based on injecting 780 ppm of Boron solution into the reactor core

Based on preventing Boron from precipitating out of solution and lowering the effective Boron concentration.
Proposed Answer:
A Explanation (Optional):
A. Correct - SR 3.1.7.3 (verify solution and piping temps >70°F) WILL be met with RB Temperature at 72
°F in the vicinity of SBLC components. Heat Trace functionality is not specified as a Surveillance Requirement
.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 186 B. Incorrect

SRO Question # 90 Given the following conditions:
A RCIC steam leak has occurred in the Reactor Building Efforts to isolate the leak are unsuccessful Water level in the RCIC Room (LI 3769) is 4 inches RCIC Emergency Cooler outlet temp (TR/TDR 2425 Ch 1) is 301°F RCIC Room ambient (TR/TDR 2425 Ch 2) is 325°F Which ONE of the following correctly completes the following statement?
Based on the conditions above, entry into Emergency Depressurization-A. is currently required because the integrity of the secondary containment is threatened.
B. is currently required because the continued operability of safety related equipment is threatened.
C. will be required if Torus East Catwalk Ambient temperature exceeds 165°F because the continued operability of safety related equipment is threatened.
D. will be required if the water level in the "A" RHR & CS SECR rises above its Max safe limit because the integrity of the secondary containment is threatened.
Proposed Answer:
C Explanation (Optional):
A. Incorrect: Emergency Depressurization is not currently required. Plausible in that both temperatures are above their Max Safe Operating Values but they are within the same area. Emergency Depressurization is performed if Max Safe values are exceeded in 2 different areas.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 188 B. Incorrect: Emergency Depressurization is not currently required. Plausible in that both temperatures are above their Max Safe Operating Values but they are within the same area. Emergency Depressurization is performed if Max Safe values are exceeded in 2 different areas.
C. Correct: When the Torus East Catwalk Ambient temperature exceeds 165°F, Max Safe limit are now exceeded in two different areas and Emergency Depressurization is required. Maximum Safe Limits are defined as the highest parameter value at which neither: (1) equipment necessary for the safe shutdown of the plant will fail nor (2) personnel access necessary for the safe shutdown of the plant will be precluded.
IAW NUREG 1021, Section 401 2.a. When selecting or writing questions for K/As that test coupled knowledge or abilities (e.g., the A.2 K/A statements in Tiers 1 and 2 and a number of generic K/A statements, such as 2.4.1, in Tier 3), try to test both aspects of the K/A statement. If that is not possible without expending an inordinate amount of resources, limit the scope of the question to that aspect of the K/A statement requiring the highest cognitive level (e.g., the (b) portion of the A.2 K/A statements) or substitute another randomly selected K/A. Predicting the impact of a steam line break on the RCIC system would be an RO knowledge. Rather than complicate the question Because we felt this was a valid K/A to test on we have only tested the second part of the K/A. D. Incorrect: Emergency Depressurization is required when the same parameter exceeds the Max Safe Values in 2 or more areas. Plausible in that a Max Safe value has been exceeded in but a different parameter.

SRO Question # 91 The plant was operating normally at power when a loss of coolant accident occurred. Conditions after the scram are as follows:
All control rods are inserted Drywell pressure is 5.5 psig and rising slowly Drywell temperature is 250°F and rising slowly RPV water level is 45 inches and slowly lowering Torus water level is 7.1 feet and slowly lowering RPV pressure 700 psig and slowly lowering Torus water temperature is 120°F and rising slowly Per the EOPs, which ONE of the following is required AND why? A. Secure Core Spray pumps to prevent cavitation damage of the pumps.
B. Place RHR in Drywell Spray to lower Drywell temperature and pressure.
C. Emergency depressurize due to compromise of pressure suppression capability.
D. Cycle SRV's to maintain RPV pressure below the heat capacity limit.
Proposed Answer:
C Explanation (Optional):
A. Incorrect
- Plausible because with the torus level so low high core spray flows would be limited by the vortex limits. However if the flow was affected by the vortex limits core spray flow should be lowered. With reactor water level lowering the core spray pumps should NOT be secured.
B. Incorrect
- Drywell pressure is too low to allow drywell sprays in that drywell temperature and pressure are not within the bounds of the Drywell Spray Initiation Limit (DSIL). Plausible in that the EOP action to initiate drywell spray would be appropriate if within the bounds of the DSIL.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 191 C. Correct - Per EOP bases Torus water level must be maintained above the bottom of the downcomer vent openings (7.1 feet) to ensure that steam discharged from the drywell into the torus following a primary system break will be adequately condensed. If a primary system break were to occur with torus water level below the bottom of the downcomers, pressure suppression capability would be unavailable and torus pressure could exceed the Primary Containment Pressure Limit.
D. Incorrect
- Plausible if the candidate does NOT realize that HCL is substantially higher for this reactor pressure. With RPV pressure between 700 and 800 psig, HCL limit is ~150°F even when including the low torus water level.

- a. One RCIC room unit cooler;
- b. One HPCI room unit cooler; and
- c. Two CS/RHR room unit coolers.
APPLICABILITY: When the associated pumps are required to be OPERABLE.
ACTIONS ---------------------------------------------------------NOTES------------------------------------------------

CONDITION REQUIRED ACTION COMPLETION TIME A. Required unit room cooler inoperable.
A.1 Declare the associated pump(s) inoperable.
Immediately
Which ONE of the following actions is required by Technical Specification s? A. No action is required because room cooler 1V-AC-12 remains operable.
B. 1V-AC-11 must be restored to service immediately because ONLY one RHR/CS Room Cooler remains operable.
C. 1V-AC-11 must be restored to service within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> because the "B" and "D" RHR and "B" Core Spray pumps must be declared inoperable D.

.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 193 Proposed Answer:
C Explanation (Optional):
A. Incorrect - There are only two RHR/CS Room Coolers, one for each ECCS division. With one cooler out of service TRM requires declaring the associated pump(s) inoperable, in this case the B and D RHR and B Core Spray pumps
. B. Incorrect
- This would apply if both loops of RHR and Core Spray were affected by the loss of one cooler. It is plausible because the TRM states than two room coolers must be operable and with one inoperable only one remains operable.
C. Correct - With 1V-AC-11 inoperable the B and D RHR and B Core Spray pumps must be declared inoperable this requires entry into TS 3.5.1.C which requires restoring one of the two systems to operable within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Since both these systems must be considered inoperable until the cooler is returned to service the cooler must be returned to service within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
D. Incorrect
- This would apply if the candidate literally reads the TRM requirement as both (Two) CS/RHR room unit coolers must be operable. This would imply that all the both RHR and CS systems are considered inoperable and therefore T.S. 3.5.1.E would apply. However as stated in the TRM Separate condition entry is allowed for each unit cooler, therefore only one of the coolers and associated RHR/CS systems are considered inoperable.

DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 195 Proposed Answer:
D Explanation (Optional):
A. Incorrect: A SITE AREA EMERGENCY was exceeded at time 0125 when the shear valve failed to fire and needed to be declared by 0140 based on EAL FS1.
Plausible if the candidate only recognizes that the RCS barrier was lost when drywell pressure exceeded 2.0 psig and determines that Unusual Event FU1 was exceeded. This would also be incorrect in that an Alert EAL was also exceeded when the RCS barrier was lost based on EAL FA1.
B. Incorrect: A SITE AREA EMERGENCY was exceeded at time 0125 when the shear valve failed to fire and needed to be declared by 0140 based on EAL FS1. Plausible if the candidate only recognizes that the RCS barrier was lost when drywell pressure exceeded 2.0 psig and determines that ALERT EAL FA1 was exceeded.
C. Incorrect: A SITE AREA EMERGENCY was exceeded at time 0125 when the shear valve failed to fire and needed to be declared by 0140 based on EAL FS1. Plausible if the candidate recognizes that the PC barrier was lost at time 0125 and thinking that the event should be upgraded to an ALERT by 0140 based on the second barrier failing.
D. Correct: The RCS barrier was lost when drywell pressure exceeded 2.0 psig. This resulted in ALERT EAL FA1 being exceeded at time 01
- 10. The ALERT was required to be declared by 0125.
Then when the shear valve failed to fire, the PC Barrier was lost at time 0125. This resulted in a SITE AREA EMERGENCY EAL being exceeded based on EAL FS1 due to having lost two barriers. The SITE AREA EMERGENCY was required to be declared within the next 15 minutes or time 0140.

DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 198 A. Correct - EOP-2, Step PC/P-7 is a Hold Point Figure regarding the PSP, this step precludes subsequent actions until the conditions listed in the Hold Point (Exceeding PSP) are met. When the conditions in the Hold Point are met, the operator continues to the next step in the flowchart and performs it. This hold point is further clarified by the Point of Emphasis, The logic phrase CAN/CANNOT BE MAINTAINED dictates that the required action should be initiated before or at the identified critical value. The value of the identified parameter(s) is/is not able to be kept above/below specified limits. This determination includes making an evaluation that considers both current and future system performance in relation to the current value and trend of the parameter(s). As specifically regards "cannot," this does not imply that the actual value of the parameter must first pass the specified limit. Proceeding actions in the EOP flow path should be directed prior to or at the stated condition.
B. Incorrect
- Emergency Depressurization can only be anticipated using the turbine bypass valves. Plausible since the MSIVs are closed.
C. Incorrect
- The logic phrase CAN/CANNOT BE MAINTAINED dictates that the required action should be initiated before or at the identified critical value. D. Incorrect
- There is no provision for restoring PSP, when it is believed PSP cannot be maintained. Emergency Depressurization must be executed.

SRO Question # 95 When proposing a design change to DAEC, the 10CFR 50.59 process determines if...
A. the change may be accomplished without prior NRC approval.
B. an evaluation for compliance with NRC Reg Guides is required
. C. a Technical Specification revision is required after implementation.
D. a Technical Specification Bases change is required after implementation.
Proposed Answer:
A Explanation (Optional):
A. Correct: 10 CFR 50.59 establishes the conditions under which licensees may make changes to the facility or procedures and conduct tests or experiments without prior NRC approval.
B. Incorrect
- Plausible because a design change may be in response to a Reg Guide however the 50.59 review does NOT evaluate compliance with NRC Reg Guides.
C. Incorrect
- Plausible because the evaluation may determine that a Technical Specifications is required. It does not, however, always require a TS revision, and it would NOT allow a TS change after the fact for a facility change. An UFSAR change is sometimes allowed to take up to 2 years to make, and this choice is additionally plausible if the candidate transferred this knowledge to TS.
D. Incorrect
- Plausible because a design change may involve a Technical Specification Bases change, however 50.59 evaluates for license (TS) amendment requirements NOT Bases revisions. A Technical Specification Bases is not part of the determination.

Proposed Answer:
C Explanation (Optional):
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 204 A. Incorrect: The AOP execution can continue provided the actions do not conflict with the EOP actions and it is approved by the shift manager. Plausible in that the EOP is the higher tier document in the hierarchy of procedure
- s. B. Incorrect: If a conflict arises the EOP takes precedent. The Shift Manager is not authorized to deviate from an EOP action.
C. Correct: IAW ACP 1410.1, EOPs can be used in conjunction with other operating procedures (OIs, ARPs, AOPs, etc.). However, EOPs are higher tier documents and shall direct the primary response to operational transients that require their use. The decision to utilize other approved procedures during EOP execution rests with the Shift Supervisor/Manager. If other plant procedures are used while executing EOPs, actions specified in these procedures shall not contradict or subvert actions described in EOPs or degrade the operability of equipment critical to EOP strategies.
D. Incorrect: There is no allowance to defer EOP actions when in an AOP.

B DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 206 Explanation (Optional):
A. Incorrect: Tech Spec 3.3.2.1 required action C.2.2 allows the startup to commence. Plausible in that Tech Spec 3.3.2.1 action C.2.1.1 would allow an already in progress startup to continue if 12 rods were withdrawn.
B. Correct: OI 878.8, RWM Precaution and Limitation # 7 states that if, at any point, the RWM is found locked up, then reset the RWM by de
-energizing and reenergizing its power per Section 6.2 of the procedure. Tech Spec 3.3.2.1 required actions C2.1.2 and C.2.2 allows rod withdraw if a startup has not been conducted within the last calendar year with the RWM inoperable and a 2nd licensed operator or other qualified individual is verifying control rod movement. Since the last plant startup was conducted on November 14, 2011 this requirement has been met.
C. Incorrect: OI 878.8, RWM Precaution and Limitation # 7 states that if, at any point, the RWM is found locked up, then reset the RWM by de
-energizing and reenergizing its power per Section 6.2 of the procedure. Plausible if the candidate is unaware of this procedure requirement and the impact of placing the RWM Mode Switch in TEST.

Proposed Question: SRO Question # 99 Following a reduction in feedwater temperature, reactor power has been lowered using recirculation flow. The OATC has determined that load line will exceed 100.64%.
Which ONE of the following is required?
The CRS will direct- A. recirculation flow be lowered as necessary to stay below the load line limit. A reactivity plan is required.
B. recirculation flow be lowered as necessary to stay below the load line limit. A reactivity plan is NOT required.
C. control rods be inserted as necessary to preclude an inadvertent violation of the load line limit. A reactivity plan is required.
D. control rods be inserted as necessary to preclude an inadvertent violation of the load line limit. A reactivity plan is NOT required. Proposed Answer:
D Explanation (Optional):
A. Incorrect
-Lowering recirculation flow will result in violating the load line limit. A reactivity plan is not required. Plausible because recirculation flow is used for fine adjustments of power and Reactivity plans are required for most power changes B. Incorrect
-Lowering recirculation flow will result in violating the load line limit. Plausible because recirculation flow is used for fine adjustments of power.
C. Incorrect
-No reactivity plan is required. This action is necessary to preclude an inadvertent violation of the 100.4% admin limit due to limitations in monitoring load line during transients. Plausible because reactivity plans are required for most power changes.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 209 D. Correct - If load line will exceed the load line limit (100.64%), then take immediate action to reduce power to the allowable region of the power to flow map with rods.
No reactivity plan is required. This action is necessary to preclude an inadvertent violation of the 100.4% admin limit due to limitations in monitoring load line during transients. IAW IPOI 3, Reactivity plans are required for all planned core reactivity changes that will result in a change in power greater than or equal to 10 percent. Also During transient Xenon conditions action should be taken at an indicated load line of 100.0% to insert control rods. No reactivity plan is required. This action is necessary to preclude an inadvertent violation of the 100.4% admin limit due to limitations in monitoring load line during transients.

SRO Question # 100 An accident has occurred which has caused entry into the RPV Flood EOP. All control rods are fully inserted.
Reactor water level is unknown RHR and Condensate are injecting into the reactor Reactor pressure is 400 psig and lowering quickly Torus water level is 10.4 feet and rising slowly Torus water temperature is 105°F and rising slowly All open SRV tailpipe temperatures are ~300°F and steady Drywell area Rad monitors are now reading 450 and 500 R/Hr and slowly rising Torus area Rad monitors are now reading 45 and 50 R/hr and slowly rising The TSC is NOT manned at this time Using the Table below which ONE of the following actions is required at this time?
A. Continue to perform RPV/F actions. SAG entry is not required until multiple Core damage indications are seen.
B. Continue to perform RPV/F actions, since core flooding indication s exist , enter the SAG s and then exit the EOPs.
DAEC NRC WRITTEN EXAM, ALL 100, REV 03 13-SLV.DOC Page 211 C. Continue to perform RPV/F actions until RPV reactor water level indications are observed. Once the TSC is operational
, exit the EOPs and enter the SAGs. D. Enter the SAGs and transition from RPV/F to SAG 1 , Primary Containment Flooding. Continue to monitor the plant for degrading conditions and report them to the TSC once manned and operational.
Proposed Answer:
C Explanation (Optional):
A. Incorrect
- RPV/F actions must continue however there is a SAG entry condition on primary containment radiation
. Plausible because RPV/F action must continue and the candidate may misinterpret Table 5.
B. Incorrect
- EOPs should not be exited until there is evidence of core flooding and the TSC is operational.
With reactor pressure still lowering and SRV tailpipe temperatures stable there is NO evidence of core flooding, with the core NOT flooded and the TSC NOT operational the EOPs should NOT be exited at this time. Plausible because there is an SAG entry condition on primary containment radiation.
C. Correct - Based upon the containment Rad levels during RPV flooding fuel damage is occurring. This requires entry to SAGs. The transition to SAGs is performed by continuing the EOP actions until there is evidence that the core is flooded or reactor water level indication is available and the TSC is operational. Once the TSC is operational, The SAGs are entered at the appropriate point and directed by the TSC and then the EOPs are exited and EOP actions terminated.
D. Incorrect
- EOPs should NOT be exited until the TSC is operational. The transition to SAGs is performed by continuing the EOP actions until there is evidence that the core is flooded. Technical Reference(s):

Wide Range Yarways (LI-4539 and LI-4540) may be unreliable due to reference leg boiling during rapid RPV depressurization below 500 psig.Operation of HPCI, RCIC, Core Spray, or RHR with suction from the torus and pump flow above the NPSH or vortex limit may damage equipment.Elevated torus pressure may trip the RCIC turbine on high exhaust pressure.The following restrictions apply to RPV water level instruments:1.If drywell air temperature is above the RPV Saturation Temperature (Graph 1), water in the instrument legs may boil. If boiling is suspected:
a.Subtract23 inches from Fuel Zone and Narrow Range GEMAC indications.b.Do not use Floodup and Wide Range Yarway instruments.2.Floodup and Wide Range instruments may not be used below the Minimum Indicated Level for the indicated drywell temperature.CAUTIONS 1 2 4 3Water may drain from isolated drywell cooling loops if well water is out of service when a PCIS Group 7 Isolation signal clears.
