RO_EXAM Q1-75 CPSES 2005 EXAM Question 1 Pressurizer safety valve 1-8010A has been slightly stuck open for the last 10 minutes.
High-pressure safety injection is maintaining RCS pressure at 1910 psig, and the Pressurizer vapor space temperature is 630°F. SI and Phase A have been reset and PRT level and pressure have been stabilized at 80% and 35 psig IAW SOP-110A, "RCDT System". A Control Room operator notes that the tail pipe temperature detector for pressurizer safety valve 1-8010A is reading approximately 280°F.
Feedwater pumps should be controlled to maintain adequate core cooling via the Steam Generators because A. break flow is greater than ECCS flow.
B. break flow heat removal is less than residual core heat.
C. break flow heat removal is greater than residual core heat.
D. break flow is less than ECCS flow.
Answer B is the correct answer, break flow heat removal is less than residual core heat. Must recognize this description is for a vapor space accident.

RO_EXAM Q1-75 CPSES 2005 EXAM Question 3 Unit 1 is currently in procedure EOS-0.2A, Natural Circulation Cooldown, step 13. The US expresses a need to cooldown at a faster rate that the rate being maintained. He announces a transition to a different procedure to increase the cooldown rate. What would be a major factor in deciding to go to a larger cooldown rate and subsequent procedure?
A. CRDM fans not available for upper head cooling.
B. Minimize risk of forming a void in the vessel.
C. RVLIS is unavailable.
D. Limited condensate storage.
Answer:
D is correct, Limited condensate storage.
A is incorrect because CRDM fans increase the cooldown rate but are not a decision factor for increasing it to the point of possible void formation. B is incorrect because a higher cooldown rate increases the risk of forming a void in the vessel (EOS-0.3 and 0.4 procedures are named accordingly). C is incorrect because the availability of RVLIS only determines which procedure (EOS-0.3A or EOS-0.4A) is used for the increased cooldown.

RO_EXAM Q1-75 CPSES 2005 EXAM Question 6 During Phase A isolation one realignment of CCW that does not occur is the isolation of CCW to RCPs because of the desire to use forced circulation cooling for this type of LOCA. For Phase B isolation, CCW is isolated because:
A. Forced circulation cooling is not desirable, CCW is at higher pressure than the Phase B set point, and any leakage into containment prior to phase B isolation would be into containment.
B. Forced circulation cooling is not desirable, CCW is at a lower pressure than the Phase B set point, and any leakage would not contribute to higher containment pressures.
C. Forced circulation cooling is not desirable, CCW is at higher pressure than the Phase B set point, and any leakage prior to phase B isolation would be into other support systems such as SSW instead of containment.
D. Forced circulation cooling is desirable, CCW is at a higher pressure than the Phase B set point, and any leakage into containment prior to phase B isolation would be into containment.
Answer:
A is correct, Forced circulation cooling is not desirable, CCW is at higher pressure than the Phase B set point, and any leakage into containment prior to phase B isolation would be into containment. Phase B isolation is designed for Large break LOCA where RCPs are not desirable.

RO_EXAM Q1-75 CPSES 2005 EXAM Question 44 Given the following conditions at Unit 1:
- 33% Reactor power.
- Main Feed PumpB is operating.
- Steam Generator Water Level Controls are in AUTOMATIC.
Which ONE of the following failures will cause RCS Tave to INITIALLY INCREASE?
A. Selected Steam Pressure Channel 1PT-514 fails HIGH.
B. Selected Level Channel 1LT-519 fails LOW C. Feed Reg Bypass Valve, LV-2162 fails OPEN.
D. Feed Header Pressure Transmitter 1PT-508 fails HIGH Answer:
D is correct, Feed Header Pressure Transmitter 1PT-508 fails HIGH. This failure causes a decrease in feed pump speed for both feed pumps and hence an increase in Tave. A is incorrect because this causes feed pump speed to increase initially, which would decrease Tave. B is incorrect because selected level failing low causes the feed water control valve to open, which would decrease Tave initially; similar discussion for C being incorrect.

A Reactor trip did not occur, and the operators have been unable to initiate a Reactor trip. All Main Feedwater pumps have tripped. Both MDAFW pumps are operating; however, the TDAFW pump has tripped and cannot be reset. With no additional operator actions, the decreased AFW flow will cause the plant to:
A. reach a LOWER RCS peak pressure because less steam is being drawn from the S/Gs.
B. reach a HIGHER RCS peak temperature because Steam Generator dryout does not occur with no steam being drawn for the TDAFW pump.
C. reach a LOWER RCS peak temperature because S/G Atmospherics and safeties pass more steam.
D. reach a HIGHER RCS peak pressure because less heat removal capability exists.
Answer:
D is correct, reach a HIGHER RCS peak pressure because less heat removal capability exists.

A is correct, N35 is over-compensated and P-6 will energize much later than normal.
For these values, N35 is the deviant detector because it is much lower than the rest, and so it is over-compensated. Because the unit is shutting down, P-6 would be reached later than normal.

The operator notices RCS level on the Mansell Level Monitor system is fluctuating and appears erroneous when compared to other vessel level indications. What could be causing this level fluctuation?
A. Considered normal when filling refueling cavity via the hot leg injection valve.
B. Mansell reference leg level is valved improperly to SDC RHR train.
C. High Flow rate on A RHR pump.
D. High Flow rate on B RHR pump.
Answer:
D is correct, High Flow rate on B RHR pump.
There are no connections to valve the instruments reference leg off of the A train of RHR, so B is incorrect. C is incorrect because Mansell level taps off of the loop 4 cross-over leg, which would only be affected by B RHR pump high flow if other level indications did not show the same results. A is incorrect because this is not normal if flow rates are set within 2k-4k gpm range as specified in the SOP.

The Control room has received a verbal report of a damaged fuel assembly by fuel handling personnel. A few moments later, an alarm sounded on the PC-11 (DRMS) for the following:
- SFP-002 LRAM SFP 2 N. WALL (X-RE-6273)
- SFP-001 LRAM SFP 2 E. WALL (X-RE-6272)
ABN-908, Fuel Handling Accident has been entered and all automatic and operator actions have been completed. What ventilation alignment is in place in the fuel building?
A. All ventilation is automatically stopped.
B. All ventilation is manually stopped by operators.
C. One supply fan in SFP area #2 is running.
D. One exhaust fan in SFP area #2 is running.
Answer:
D is correct, One exhaust fan in SFP area #2 is running.
A is incorrect because there are no automatic signals to isolate ventilation for high radiation in the fuel building. No instruction is given for operators to manually stop all ventilation in the ABN, hence B is incorrect. C is incorrect because the ABN instructs the exhaust fan to be kept running.

SRO ONLY QUESTIONS Q75-100 CPSES 2005 EXAM Question 88 Unit one is at 86% power due to one Main steam safety valve (MSSV) MS-021 failing its IST program. The Control Room Supervisor reviews the Technical Specification section 3.7.1 for the MSSV's and notes that there are two required action steps for this condition and both must be performed:
- 1) a power reduction and
- 2) a high power reactor trip reduction.
The basis for both actions is:
A. When MTC is positive, there is insufficient remaining steam flow capacity to prevent overpressurizing the steam system during an uncontrolled bank RCCA withdrawal.
B. When MTC is negative, there is insufficient remaining steam flow capacity to prevent overpressurizing the steam system during a turbine trip.
C. When MTC is positive, there is insufficient heat removal capacity to protect the RCS pressure boundary from an RCS heating event.
D. When MTC is negative, there is insufficient remaining steam flow capacity to prevent overpressurizing the steam system during a turbine trip.
Answer:
A is correct, When MTC is positive, there is insufficient remaining steam flow capacity to prevent overpressurizing the steam system during an uncontrolled bank RCCA withdrawal.

SRO ONLY QUESTIONS Q75-100 CPSES 2005 EXAM Question 91 Unit 1 Core Exit Thermocouples (CET) are currently reading 1300 degrees F. Loops 1 and 2 have RCPs running. The in-progress procedure step for depressurizing all intact SGs to atmospheric pressure has just been completed and the CET temperatures are decreasing. What procedure should you be implementing to mitigate/prevent core damage?
A. FRC-0.1A, Response to Inadequate Core Cooling.
B. SACRG-1, Severe Accident Control Room Guideline Initial Response.
C. EOP-1.0A, Loss of Reactor or Secondary Coolant.
D. EPP-312-1, Core Damage Assessment and Prevention.
Answer:
A is correct, FRC-0.1A, Response to Inadequate Core Cooling.
With 2 RCPs running and CET temps decreasing and recognizing that the current procedure is FRC-0.1A, staying in FRC-0.1A is correct. If CETs were still increasing after the depressurization then an exit of this procedure and entry to SACRG-1 would be required (why B is incorrect). C is incorrect because CETs are greater than 1200 deg F, 1 of 3 requirements needed to exit FRC-0.1A and enter EOP-1.0A. D is incorrect because no prevention steps are provided in this document (title is partially fictitious).
