NRC Site-Specific Written Examination Callaway Plant Reactor Operator Examination Outline Cross-reference: Level RO SRO Tier # 1 Group # 1 K/A # 015/017 AK3.02 Importance Rating 3.0 3.1 Knowledge of the reasons for the following responses as they apply to the Reactor Coolant Pump Malfunctions (Loss of RC Flow) : CCW lineup and flow paths to RCP oil coolers Question #3 Given the following plant conditions:
The Callaway Plant is operating at 100% power.
EG HV-59, CCW from Ctmt Outer Isolation Valve closed 2 minutes ago due to an electrical short and cannot be opened.
EG HV-60, CCW from RCS Inside Ctmt Isolation Valve has remained open. Highest Upper Radial Bearing temperature is currently reading 196°F and rising on all RCPs.
In accordance with OTO-BB-00002, RCP Off-Normal, which ONE of the following actions, if any, is required and why?
A. Pumps can remain in service since CCW flow to oil coolers will be maintained through return valve EG HV-61, CCW from RCP Thermal Barrier Outer Ctmt Isolation.
B. Pumps can remain in service until RCP Bearings Cooling Water Return High Temperature annunciator is received.
C. Reactor must be tripped and ALL RCPs stopped due to loss of CCW flow to ALL RCP motor bearing coolers.
D. Reactor must be tripped and "A" and "B" RCPs stopped due to loss of CCW flow to their respective oil coolers.
Justification A. Incorrect. All CCW flow is lost B. Incorrect. Action is not conservative alarm and plant does not have high temp alarm. C. Correct. Step C1 RNO is performed because the temp is >195 F. D. Incorrect. All RCPs must be tripped.
The cooling water passes through the thermal barrier heat exchanger and then through an orifice metering device (FT-17, 18, 19, 10). The flow device will shut a motor operated valve (BB-HV-13, 14, 15, 16) downstream of the thermal barrier on a sensed high CCW flow in excess of 50 gpm. This high flow would be indicative of a primary to CCW leak in the thermal barrier heat exchanger. Similarly, in the common return line for the CCW, from all the thermal barrier heat exchangers is another motor operated valve (EG-HV-62) which will automatically shut on a combined CCW return flow of greater than 206 gpm as sensed by flow device FT-62 in the common return line.
Component Cooling Water to the RCPs will also be automatically isolated on a Phase B Containment Isolation Signal (CISB). The CISB can be generated by either a containment pressure of 27 psig (High 3) on a 2 out of 4 coincidence, or by manual actuation of containment spray. The signal will cause the following six valves to shut:

Question #23 Given the following plant conditions:
A Small Break LOCA has occurred. Due to a failure of Voltage Restoration for Buses PA01 and PA02, these buses are deenergized. The actions of ES-1.2, Post LOCA Cooldown and Depressurization, are in progress. Charging Pumps "A" and "B" are running with suction aligned to the RWST. Both RHR Pumps are stopped in AUTO. Both SI Pumps are running. The crew is ready to depressurize the RCS to refill the Pressurizer.
Which ONE of the following describes how this depressurization will be achieved?
A. Utilize Pressurizer Auxiliary Spray Valve, BGHV-8145, to spray down the Pressurizer steam space.
B. Utilize BOTH Pressurizer Spray Cont rol valves, BB-PCV-455B AND BB-PCV-455C, to spray down the Pressurizer steam space.
C. Open BOTH Pressurizer PORVs, BB-PCV-455A and BB-PCV-456A to vent the Pressurizer.
D. Open ONE Pressurizer PORV, BB-PCV-455A or BB-PCV-456A to vent the Pressurizer.
Justification A. Incorrect. BGHV-8145 is a method for depressurization and for a SGTR is utilized as the third method. However, it is not used in this case since the requirements place a limit of spray dT, and letdown is required to be in service if Aux Spray is to be used. B. Incorrect. This is the "normal" method used to depressurize the RCS. However, with Buses PA01 and PA02 deenergized, the RCPs are NOT running and are therefore unable to provide the driving head for normal sprays. C. Incorrect. Opening TWO PORVS is not an appropriate action. This action has a less stable depressurization rate and raises the probability of a PORV failing to close. D. Correct.

C. Prevent excessive cooling to the spray line.
Ensure that the backup heaters cycles on.
D. Minimize stress to the surge line thermal sleeve. Remove gases from the RCS.
Justification A. Correct. B. Incorrect, see below description C. Incorrect, see below description D. Incorrect, see below description
Each spray valve is paralleled with a manual throttle valve which allows a small continuous flow of 1/2 gpm for each leg through the spray lines. This flow aids in reducing the thermal stresses and thermal shock when the spray valves open, and helps maintain uniform water chemistry and temperature in the pressurizer. The spray nozzle is further protected from thermal shock by low alarm temperature sensors that alert the operator to an insufficient bypass flow condition. The piping layout to the nozzle forms a water seal, preventing steam buildup back to the spray valve.
Requires candidate to know the different purposes for spray bypass flow.

Question #70 Given the following plant conditions:
Callaway Plant is operating at 75% power. Transformer checks were being conducted in the switchyard. A grid disturbance caused NB 02 bus voltage fluctuations. MCB Annunciator "NB02 Bus Degraded Voltage" had been coming in intermittently, but has now been lit continuously for 60 seconds.
Which ONE of the following conditions will trip the normal supply breaker NB0209?
A. A Containment Spray Actuation Signal is actuated.
B. NB02 voltage drops to 3800 volts.
C. A Safety Injection Signal is actuated.
D. The annunciator remains lit 25 seconds longer.
Justification A. Incorrect, SI signal B. Incorrect, </= 3761 C. Correct. D. Incorrect, need to be 87 to 104
- A time delay of 111 + 8 second allows time for the Control Room Operator or Grid Operations to correct the undervoltage condition before NB feeder breakers trip. The degraded voltage relay bistable also incorporates a time delay of 8 second for a total of 119 + 8.5 second.
- Alarm comes in after 22 + 1.0 seconds of Degraded Voltage Condition. This allows for the starting of a RCP motor without receiving an undervoltage trip. Load shed occurs after 119 seconds of degraded voltage condition and 97 seconds after alarm of this annunciator. However, if a Safety Injection Signal is present, load shed will occur after 8 seconds of degraded voltage.
When 87 to 104 seconds has elapsed, the following will occur:
- NB HIS-4, NB02 NORM SPLY BKR NB0209, opens
- NB HIS-5, NB02 ALT SPLY BKR NB0212, opens

Question #82 Given the following plant conditions:
The plant is stable at 85% power. RCS T avg is on program. Pressurizer pressure is 2230 psig.
Control Bank 'D' is at 160 steps withdrawn. The Control Rod Bank Selector is in AUTO.
Control Bank 'D' then begins to step out at minimum rod speed. Rod Control System automatic rod blocks fail to function.
With no operator action, which ONE of the fo llowing would generate t he reactor trip to provide protection and what is the basis?
Generating Signal Basis A. Pressurizer low pressure reactor trip Prevent exceeding power density in the core B. Overtemperature T reactor trip Prevent exceeding DNB C. Power range positive rate trip Prevent exceeding power density in the core D. Overpower T reactor trip Prevent exceeding DNB
Justification A. Incorrect. Rods stepping out would increase temp, which would increase pressure. B. Correct. T avg and pressure increase lowers the setpoint to trip first. C. Incorrect. Would not reach setpoint at minimum rod speed.
D. Incorrect. Runback would occur first.
As stated in TS Bases, the OTT reactor trip provides core protection against DNB for all combinations of pressure, power, coolant temperature and axial power distribution, provided only that : 1) the transient is slow with respect to piping transit delays from the core the the temperature detectors (about 2 seconds), and 2) pressure is within the range between the high and low pressure reactor trips. The USAR Accident Analysis confirms the OTT reactor trip is expected to limit this transient. For a slow RCCA withdrawal (3.0E-5 k/sec) from full power... Reactor trip occurs on Overtemperature T reactor trip... The minimum DNBR reached during the transient is greater than the MDNBR (Minimum DNB Ratio).
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator OPT reactor trip prevents the power density anywhere in the core from exceeding that value at which fuel pellet centerline melting would occur (as compare to DNB).
The positive rate trip is designed for a rod ejection or an uncontrolled RCCS bank withdrawal. The setpoint would not be reached for this event prior to OTT. Pressurizer pressure is expected to rise during the rod bank withdrawal accident and no challenge is provided to low pressure reactor trip.
