B. Incorrect - This is the broad range of water level requirements during an ATWS it would not apply if RPV Flooding is entered.
C. Correct - RPV flooding, is used to cool the core when RPV water level cannot be determined. The specified actions first depressurize the RPV, then control injection to establish and maintain one of the following conditions:
- The RPV flooded to the elevation of the main steam lines. The core will then be cooled by full submergence. This condition may ultimately be achieved under either shutdown or failure-to-scram conditions.
- RPV pressure above the Minimum Steam Cooling Pressure. The core will then be cooled by submergence or steam cooling. Since reactor power must be at least 6%-
10% to generate the amount of steam required to sustain the Minimum Steam Cooling Pressure, this condition is applicable only under ATWS conditions.
D. Incorrect - The direction of RPV/F EOP is to maintain water level at the Main Steam Lines, not the RPV head. The 150 psig is the minimum steam cooling pressure for 4 SRVs open.

A. A turbine trip has occurred on low flow.
B. A turbine trip has occurred on overspeed.
C. A turbine trip has occurred on low oil pressure.
D. A turbine trip has occurred on low pump suction pressure.
Proposed Answer: B ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - A low flow condition would not cause a turbine trip B. Correct - A turbine overspeed trip will only cause an alarm on the turbine trip. The low oil pressure and low flow result from the turbine speed coasting down after the RCIC turbine trip.
C. Incorrect - During a loss of oil pressure the turbine will overspeed because the RCIC turbine control valve is opened by spring pressure and closed by oil pressure.
D. Incorrect - There is no indication that MO-2404 failed to close.

Plant-Specific Question: RO Question # 8 The plant is operating in MODE 4 in Shutdown Cooling with the following conditions:
- RPV level is 190 inches
- The A RHR pump and A RHRSW pump are running An event occurs that causes RPV level to rapidly drop to 50 inches.
Which one of the following describes how the RHR pumps automatically respond to the signal?
A RHR Pump C RHR Pump A. Trips and restarts Starts and operates when the system on minimum flow automatically realigns to a LPCI mode B. Trips and does not Starts and operates restart on minimum flow C. Trips and does not Attempts to start and restart immediately trips D. Trips and restarts Attempts to start and when the system immediately trips automatically realigns to a LPCI mode Proposed Answer: C ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - The "A" pump trips. All others start but C trips. the RHR System will not automatically realign itself for LPCI injection B. Incorrect - The "A" pump trips and does not restart. All others start but C trips C. Correct - Per SD 149, page 22 - In the event a LOCA occurs when the RHR System is in the shutdown cooling mode, the RHR System will not automatically realign itself for LPCI injection. Operator actions required to initiate the LPCI mode of RHR include resetting the Group 4 Isolation Seal-In, restoring torus suction flowpath to the RHR pumps, and manually restarting the RHR pumps that have tripped.
Additionally, the SDC suction valves close on the LPCI signal (PCIS Group 4). The "C" RHR Pump breaker will receive a start signal but immediately trip. The trip occurs due to no suction path present to prevent pump damage. This is NOT a start permissive, it s a pump trip (SD-149 page 12)
D. Incorrect - The "A" pump trips. The "C" RHR Pump breaker will receive a start signal but immediately trip. The trip occurs due to no suction path present to prevent pump damage. This is NOT a start permissive, it s a pump trip (SD-149 page 12).

- All LCOs are met Which one of the following is a consequence of prolonged operation the Control Building Ventilation System in the PURGE mode?
The PURGE mode ...
A. bypasses the heating and cooling coils resulting in loss of Control Building temperature control.
B. isolates the outside air intake lowering Control Building pressure below atmospheric pressure.
C. ventilation flow bypasses the Cable Spreading and Battery Rooms which may result in having to declare the Batteries inoperable.
D. closes the Control Room Recirculation Damper which could result in more rapid buildup of radiological or toxic chemical concentrations.
Proposed Answer: D ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - When HS 6107 is placed in the Fresh Air mode of operation, the Control Room Recirculation Damper DO6109 fully closes, this mode does not bypass the heating and cooling and temperature is not a concern.
B. Incorrect - Damper Operator DO6106A(B) maintains mixing plenum (supply fan suction)
.25"wg greater than outside pressure.
C. Incorrect - Placing the Control Building Ventilation system in the PURGE mode does not bypass the Cable Spreading and Battery Rooms.
D. Correct - When HS 6107 is placed in the Fresh Air mode of operation, the Control Room Recirculation Damper DO6109 fully closes. The basis for use of the fresh/auto (purge) mode is at the discretion of the OSM/CRS for comfort in the control room only. If the control building ventilation is operated in purge mode for extended periods, and a radiological or toxic chemical event were to occur, the higher intake flow rate in PURGE mode could result in more rapid buildup of radiological or toxic chemical concentrations than has been assumed in the safety analysis.

Question: RO Question # 31 Which one of the following describes the design basis function of the Rod Worth Minimizer?
It enforces A. rod withdrawal with a programmed control rod sequence to limit the power excursion to prevent rapid dispersal of the fuel in the event of a Control Rod Drop Accident (CRDA)
B. control rod sequences designed to prevent exceeding the Minimum Critical Power Ratio when Reactor power is below 21.7% Rated Thermal Power C. programmed rod movement that minimizes individual control rod worth to prevent exceeding the Maximum Extended Load Limit Analysis (MELLA) while in MODE 2 D. control rod sequences to limit the rate of heat production to < 280 calories/gram of fuel during control rod withdrawal when reactor power is > 21.7%.
Proposed Answer: A ILT Exam 7/12/2011
Explanation (Optional):
A. Correct - Since the worth of an individual rod is highly dependent on core power distribution, rod sequence control provides a means of restricting the maximum reactivity insertion that could occur in a CRDA. The principal function of the NUMAC RWM is to limit rod motion such that high worth rods are not created, thereby limiting the maximum reactivity which could be added due to a control rod drop accident.
B. Incorrect - This is not a design function, the RWM does ensure that fuel operating limits are not exceeded and that the possibility of a high notch worth scram occurring is minimized.
C. Incorrect - This is not a design function, the RWM does ensure that fuel operating limits are not exceeded and that the possibility of a high notch worth scram occurring is minimized.
D. Incorrect - The RWM limits the rate of heat production to < 280 calories/gram of fuel during rod DROP accident NOT a control rod withdrawal. And the power level is when reactor power is <10%.

- Drywell temperature has raised to 350°F
- RPV pressure is stable at 100 psig
- The Action Is Required area of EOP Graph 1 has been entered Which of the following statements is correct regarding the RPV level instruments?
A. RPV actual level and indicated level will be equal under these conditions.
B. RPV actual level may be higher than indicated level due to boiling in the RPV.
C. RPV indicated level may be higher than actual level due to reference leg heating.
D. RPV level may only be read on the Floodup and Wide Range Yarway instruments.
Proposed Answer: C ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - Because of the lower density of the reference leg indicated level will be higher than actual level.
B. Incorrect - With the reactor stable the temperature (~338°F) is above drywell temperature so no boiling in the reference or variable legs will occur. Indicated level may be higher than actual level due to reference leg heating.
C. Correct - With the reactor stable, an increase in containment temperature would cause an increase in the temperature of the reference leg. This would lower the density making the reference leg "lighter". Because level is derived by a dp cell measuring the difference in weight, the decrease in the weight of the reference leg would cause a loss of inventory from the reference legs which would result in erroneously high indications D. Incorrect - the Floodup and Wide Range Yarway instruments will be affected although they may still be used for level indication the GMAC level indicator also provide level indication.

- A Loss of Vacuum event occurred
- A manual Reactor Scram was inserted
- All Control Rods are Full In
- Bypass Valves have failed closed.
- Low Low Set is NOT working Under these conditions stabilizing reactor pressure less than 1055 psig will ___(1)___ and
___(2)___.
A. (1) avoid repeated operation of the SRVs on high reactor pressure (2) prevent SRV damage due to two phase flow B. (1) allow the operator to manually reset the ATWS ARI/RPT logic if it initiated on high reactor pressure (2) prevent potential SRV damage due to the frequent cycling C. (1) avoid repeated operation of the SRVs on high reactor pressure (2) assist in maintaining RPV level below the high level trip setpoint D. (1) allow the operator to manually reset the ATWS ARI/RPT logic if it initiated on high reactor pressure (2) assist in maintaining RPV level below the high level trip setpoint Proposed Answer: C ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - This will avoid repeated operation of the SRVs on high reactor pressure however the concern with SRV openings is RPV level swell.
B. Incorrect - manual reset of the scram would be possible NOT ATWS ARI/RPT logic.
The concern with SRV openings is RPV level swell.
C. Correct - Per EOP 1 Bases - Swell resulting from SRV actuation may result in high level trips of steam driven systems even if level is maintained low in the normal band. It may then be necessary to define a wider control band to maintain level below the high level trip setpoint. Bases for RC/P-4 step Stabilize RPV pressure Below 1055 psig - The direction to stabilize RPV pressure in Step RC/P-4 means to limit changes in RPV pressure (both increases and decreases) to within as small a band as possible.
Controlling RPV pressure below this value avoids SRVs lifting on high pressure and allows the scram logic to be reset (provided no other scram signal exists).
D. Incorrect - manual reset of the scram would be possible NOT ATWS ARI/RPT logic.

Under these conditions, ___(1)___ could cause the drywell to exceed its ___(2)___ design pressure limit.
A. (1) a Torus to Drywell Vacuum Breaker failing OPEN (2) internal.
B. (1) a Torus to Drywell Vacuum Breaker failing CLOSED (2) external C. (1) a Reactor Building to Torus Vacuum Breaker failing OPEN (2) external D. (1) a Reactor Building to Torus Vacuum Breaker failing CLOSED (2) internal Proposed Answer: A ILT Exam 7/12/2011
Explanation (Optional):
A. Correct - IAW SD 959 - Containment Characteristics after LOCA with Torus /Drywell Vacuum Breaker Failed Open - Steam flows from the drywell to the torus through the vacuum breaker equalizing the pressure. The steam is not forced through the downcomers and up through the water, but instead is dumped on the surface of the water in the torus. As a result, the drywell pressure will probably exceed design pressure.
B. Incorrect - In this condition, drywell pressure could lower and cause the Torus to Drywell differential pressure to exceed 2 psid.
C. Incorrect - correct if the vacuum breaker failed closed D. Incorrect - IAW SD 959 page 25, if a reactor building to torus vacuum breaker were to be failed closed in the case of a DBA, there would be little effect. The purpose of the reactor building to torus vacuum breakers is to ensure that neither the torus nor drywell exceed their external pressure limit.

(1) The HPCI Turbine Exhaust will become uncovered (2) 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 HPCI Turbine Exhaust, pressure suppression capability would be unavailable and torus pressure could exceed the Primary Containment Pressure Limit.

(1) The RCIC Turbine Exhaust will become uncovered (2) 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 RCIC Turbine Exhaust, pressure suppression capability would be unavailable and torus pressure could exceed the Primary Containment Pressure Limit.
Proposed Answer: A ILT Exam 7/12/2011
Explanation (Optional):
A. Correct - EOP 2 Bases Step TL/6 - (1) A torus level of 5.8 feet corresponds to the HPCI turbine exhaust elevation.
(2) Operation of the HPCI system with its exhaust device not submerged will directly pressurize the torus. HPCI operation is therefore secured when torus level cannot be maintained above 5.8 feet to preclude pressurizing the torus. The consequences of not doing so may result in failure of the primary containment from over pressurization. Thus, HPCI must be secured irrespective of adequate core cooling concerns.
B. Incorrect - (1) The HPCI turbine exhaust level is 5.8 feet (correct), however (2) the discussion is the bases discussion for the 7.1 ft torus level.
C. Incorrect - (1) The RCIC turbine exhaust is at the approximate same level, but the RCIC is not tripped due to: The exhaust flowrate of RCIC is approximately equal to that of decay heat, and is thus consistent with the basis used for determining the Primary Containment Pressure Limit and Elevated Torus pressure will cause the RCIC turbine to trip before the HPCI turbine would trip. (Refer to the discussion of Caution 4)
D. Incorrect - (1) The RCIC turbine exhaust is at the approximate same level, but the RCIC is not tripped due to: The exhaust flowrate of RCIC is approximately equal to that of decay heat, and is thus consistent with the basis used for determining the Primary Containment Pressure Limit and Elevated Torus pressure will cause the RCIC turbine to trip before the HPCI turbine would trip.

Which of the following describes the reason for this requirement?
It is required to lower RPV Water Level to at least 87 inches to _______.
A. reduce natural circulation and limit the peak power level to below the fuel thermal limits B. uncover the feedwater spargers to reduce subcooling and limit the onset of reactor power / core flow instabilities C. isolate RWCU to prevent boron removal by the system and limit the peak power level to below the fuel thermal limits D. trip the operating Recirculation Pumps to reduce forced circulation and limit the onset of reactor power / core flow instabilities Proposed Answer: B ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - the concern is core instabilities.
B. Correct - IAW EOP ATWS Bases Continuous Recheck Statement - The conditions expressed in this Continuous Recheck Statement, combined with the inability to shutdown the reactor through control rod insertion, dictate a need to promptly reduce reactor power in order to prevent or mitigate the consequences of any large irregular neutron flux oscillations induced by neutronic/thermal-hydraulic instabilities. This is accomplished by transferring to entry point 7 and lowering RPV water level to +87 inches in Step /L-2. An RPV water level of +87 inches is 2 feet below the lowest nozzle in the feedwater sparger. This places the feedwater spargers in the steam space providing effective heating of the relatively cold feedwater and eliminating the potential for high core inlet subcooling.
C. Incorrect - RWCU is verified isolated, but the reason for lowering level to 87 inches is NOT based on RWCU automatic isolation at 119.5 inches D. Incorrect - RR Pumps will be verified tripped if power is above 5%, but the reason for lowering level to 87 inches is NOT based on RR Pump ATWS RPT at 119.5 inches.

Question: RO Question # 55 A transient resulted in the following plant conditions:
- RPV level is 60 inches and steady
- RPV pressure is 800 psig and lowering slowly
- Torus and Containment Sprays have been initiated once
- Drywell Pressure is 1.6 psig and steady
- Drywell Temperature is 100°F and steady
- Torus Temperature is 102°F rising slowly The Control Room Supervisor directs the operator to maximize torus cooling. Is this allowed by current plant conditions? Why or why not?
A. Yes, since adequate core cooling has been assured, the operator may establish Torus Cooling.
B. Yes, since there is less than a 2 psig drywell pressure signal, the operator may establish Torus Cooling.
C. No, since RPV level is less than 64" and drywell pressure is less than 2 psig, Torus Cooling may NOT be established.
D. No, since RPV pressure is 800 psig and LPCI loop select has selected a loop, Torus Cooling may NOT be established.
Proposed Answer: C ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - There is precaution on verifying adequate core cooling and with 60 in the RPV adequate core cooling is assured, however the torus cooling valves cannot be opened with less than 2 psig in the drywell and the LPCI signal still in.
B. Incorrect - The torus cooling valves cannot be opened with less than 2 psig in the drywell and the LPCI signal still in.
C. Correct - IA OI-149, Sect 5.3, pg 32, The Containment Spray and Cooling valves are interlocked closed when Drywell pressure is < 2 psig with a LPCI Initiation signal present. The LPCI signal is still present because the RPV water level is <119.5 inches.

Examination Outline Cross-reference: Level RO SRO Tier # 2 Group # 1 K/A # 295022 2.1.20 Importance Rating 4.6 Conduct of Operations: Ability to interpret and execute procedure steps. (Loss of CRD pumps)
Question: RO Question # 64 The plant is operating in MODE 1 at 100% power with the following conditions:
- The A CRD pump out of service to replace the motor bearings
- The 1A4 bus suffers a lockout trip and is de-energized Due to a loss of drywell cooling, the CRS directs a manual reactor scram.
What will be the effect on the control rods and subsequent actions?
A. Control rods will fully insert slower than normal on the scram. IPOI-5 and EOP-1 will be entered.
B. Control rods will fully insert at normal speed on the scram. IPOI-5 and EOP-1 will be entered..
C. Control rods will NOT fully insert on the scram. EOP-1 will be entered and transferred to EOP-ATWS for actions to be directed. Actions directed will be for a LOW power ATWS.
D. Control rods will fully insert on the scram. EOP-1 will be entered and then IPOI-5. A CRD pump must be re-started before the scram is able to be reset.
Proposed Answer: B ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - Control rods will insert into core without CRD pump running. The scram time testing STP has the charging water isolation valve shut prior to running the scram time test. This is equivalent to losing both CRD pumps. The rods do not insert slower than with the CRD pumps running.
B. Correct - Control rods insert without CRD pump, EOP 1 will be required to be entered on the RPV level shrink, and IPOI-5 is the scram procedure.
C. Incorrect - Control rods will insert into core without CRD pump running. This answer is plausible if the candidate believes that the rods will partially insert, but not go full in.
D. Incorrect - CRD pump is not required to reset the scram.

Main Steam Isolation Valves are required to be ____.
A. open, to allow Main Steam flow to assist in rapidly depressurizing the RPV and ensure boron is mixed throughout the vessel.
B. open, to allow flooded RPV indications to be obtained from Main Steam Line Flow Instruments.
C. shut, the primary concern is to avoid excessive water inventory loss from the RPV during flooding.
D. shut, to ensure adequate boron concentration in the vessel and avoid damage to downstream equipment.
Proposed Answer: D ILT Exam 7/12/2011
Explanation (Optional):
A. Incorrect - The MSIVs are shut in EOP-ATWS step RPV/F-12. Boron would be diluted if the MSIVs were open B. Incorrect - The MSIVs are shut per the EOP C. Incorrect - Inventory loss is not the concern.
D. Correct - The MSIVs are shut in EOP-ATWS step RPV/F-12. IAW the bases, If the MSIVs were not closed, boron would be lost from the RPV when water level reached the elevation of the main steam lines. Leaving the MSIVs open would also risk damage to downstream equipment that might be needed during later recovery actions.
