REFERENCE:
APP A-5 (2-2) Rod Out Block, (3-2) Rod Drift and (5-2) Rod Block RWM/RMCS Trouble AOP-2.0 Control Rod Malfunction/Misposition EXPLANATION:
A Rod Drift alarm is generated if an odd numbered reed switch is picked up with no "rod selected and driving" signal present. An inadvertant rod scram will cause a rod drift alarm. Below the LPAP, a rod drift/scram can cause a rod insert/withdraw from the RWM. This error will cause a Rod Block RWM alarm on A-5 (5-2) The given plant conditions are above the LPAP. No Rod Out Block alarm or Rod Block RWM alarm will be received.
Per the direction of AOP-2.0, supplementary action 3.2.2, "IF greater than 25% RTP and the sum of scrammed and inoperable control rods is no more than eight, then REDUCE core flow to 65 mlbs/hr. CHOICE "A" -Incorrect.
No Rod Out Block alarm will be received.
Manual Scram is an incorrect action for these conditions.
If reactor power were below the LPAP, a Rod Block RWM alarm be received.
If two rods had been drifting, a Scram would be appropriate per AOP-2.0. CHOICE liB" -Incorrect.
No Rod Out Block alarm will be received.
CHOICE "C" -Incorrect.
Manual Scram is an incorrect action for these conditions.

CLS-LP-07, Obj. 11 b -describe the possible causes and required operator actions for the following alarms: A-S 3-2, Control Rod Drift. COG LEVEL: High Page 2 of 42
Plant conditions are as follows: Reactor Pressure Reactor water level Drywell Pressure Drywell Temperature Torus Pressure Torus Temperature Torus Level Core Spray Loop B Core Spray Loop A RHR Loop B RHR Loop A RHR Pump 2A Overload 2A RHR Pump Amps 55 psig o inches and rising 17.6 psig 246 0 F 15.9 psig 135 0 F -3.5 feet Injecting at rated flow Injecting at rated flow Injecting at rated flow Flow is oscillating In alarm Fluctuating Considering current plant conditions, which one of the following is a possible cause for these RHR pump indications and what actions are correct per plant procedures?
Low NPSH due to ____ _ A. clogging suction strainers; Continue running 2A RHR Pump irrespective of NPSH limitations clogging suction strainers; Secure 2A RHR Pump and verify reactor water level still rising C. high Torus Temperature
/ low torus level combination:
Continue running 2A RHR Pump irrespective of NPSH limitations D. high Torus Temperature
/ low torus level combination:
Secure 2A RHR Pump and verify reactor water level still rising Page 3 of 42
REFERENCE:
SO-17 Residual Heat Removal System Reactor Vessel Control Procedure APP A-01 (4-8) RHR Pump 2A Overload EXPLANATION:
Low NPSH is caused by insufficient pump suction head. Elevated torus temperatures as well as suction strainer clogging are potential causes. The lowest torus temperature at which NPSH limits become a concern for RHR pumps at BNP is 160°F. Suction strainer clogging has occured at several nuclear plants. Although it is less likely since the suction strainer modifications, it is still a possibility.
As the strainers clog, pump amps and flows will fluctuate.
Pump overload alarms may be received.
For the given conditions, (overload alarm, level above TAF and rising, multiple injection sources) the appropriate action per RVCP and the APP would be to secure the RHR pump and verify level still rising) CHOICE "A" -Incorrect.
With reactor water level above TAF and rising injection flow is not required irrespective of NPSH limitations CHOICE "B" -Correct Answer CHOICE "C" -Incorrect.
With current torus temperature, NPSH limits are not a concern CHOICE "0" -Incorrect.
With current torus temperature, NPSH limits are not a concern 203000 RHRlLPCI:

REFERENCE:
001-01.08 Control of Equipment and System Status, section 5.1.2.4 ECCS Rm Clrs AP-13 Plant Equipment Control EXPLANATION:
Per the direction of 01-01.08, when any room cooler is determined to be inoperable, then the ECCS equipment associated with that room cooler must be declared INOP per the applicable TS. CHOICE "A" -Correct Answer CHOICE "B" -Incorrect.
001-01.08 already clarifies OPERABILITY determination.
If student is unaware of 01-01.08 guidance, they may choose this answer. CHOICE "C" -Incorrect.
Per AP-13 a tripped breaker should not be reset until an investigation has been performed, except in case of an emergency.
If this were an emergency condition, this an could be correct. CHOICE "D" -Incorrect.

SO-03 Reactor Protection System, section 3.1 RPS Trips AOP-22 Grid Instability, step 3.2.4 EXPLANATION:
A load reject signal at any reactor power level will cause a turbine control valve fast closure scram. The load reject signal does not input into the turbine stop valve closure scram logic. During a grid instability event, with only one 230 KV line feeding the system, a supplementary action of AOP-22 is to ensure that lines PCB auto recloser is OFF. CHOICE "A" -Incorrect Tripping the Whiteville PCB is not an action required for these conditions.
CHOICE "B" -Incorrect Load reject initiates a TCV fast closure scram only. A misconception of the difference between TCV and TSV scrams may cause a student to select this answer. CHOICE "C" -Correct Answer CHOICE "0" -Incorrect.

A. B CRD Pump is running with no power to the flow controller.
Swap flow controllers locally. No CRD pumps are running with no power to the flow controller.
Start B CRD Pump and transfer 1 AB-to its alternate power supply. C. B CRD Pump is running with a loss of power to its cooling water solenoid.
Shift 1AB-TB to alternate power supply. D. No CRD pumps are running with a loss of power to the cooling water solenoids.
Cross-tie E5 and E6 to start B CRD pump, and shift 1 AB to alternate power supply.
REFERENCE:
OAOP-36.1 EXPLANATION:
with a loss of all offsite pOJNer the E-Buses will strip the loads (CRD Pumps), there are no auto starts for these pumps, so both CRD pumps will be off. DG1 is lost which means E1 is lost and A CRD pump will not be able to be started.'
E5 to E6 would not be crosstied unless emergency conditions exist. The CRD flow controller is powered from 1 AB which will need to be transferred to its alternate power supply. The cooling solenoid for the A CRD pump is powered from 1A. The actions in the AOP state to restart CRD per the OP and transfer 1AB-RX, 31AB, and 1AB to their alternate power supply. CHOICE "A" B CRD is not running it would have been load stripped.
There is no power to the controller and swapping them locally will not change that fact. CHOICE "B" correct answer. CHOICE "C" B CRD is not running it would have been load stripped.
If 1AB-TB is transferred then it will not have any power, its normal power is from E6 and alternate power is from E5. CHOICE "D" Crosstieing E5 and E6 will not get any power to the pump but will get power to the cooling water solenoids.
Since an emergency condition does not exist then this action should not be taken. If E5 to E6 crosstie is performed then there is no reason to swap 1AB to its alternate power supply.
