Reactor Power .....................100%

Total core flow ....................98 Mlbm/hr

Recirc Pump "A" speed........85%

Recirc Pump "B" speed........84%

The following events occur:

09:10:00..........Breaker 65G-G3 trips open

09:10:20..........Recirculation Pump "A" trips

09:12:00..........Loss of Heater Drains due to power reduction At 09:20:00, with no operator action, what is the indicated demand on the RR MG Set Speed Controllers?

Response A Loop A - 40% , Loop B - 40%

40% is the setpoint for the 2/3 Limiter, which is not in effect.

Response B - Correct Answer Loop A - 28% , Loop B - 75%

References 1, 2, 3, 4 Response C Loop A - 28% , Loop B - 40%

Loop A would be at 28% due to failed breaker being open, 40% is the setpoint for the 2/3 Limiter, which is not in effect.

Response D Loop A - 28% , Loop B - 28%

Loop A would be at 28% due to failed breaker being open, Loop B would be at 28% due to failed breaker being open, which did not heppen.

Select the statement that correctly describes the plant response.

Response A Power is lost to the RCIC logic circuit which will result in RCIC failing to auto start on a valid initiation signal.

RCIC logic circuit is powered from ESF DC.

Response B - Correct Answer Power is lost to the Main Turbine Trip circuits resulting in a Main Turbine Trip and a Reactor Scram.

Reference - 1 Response C The running Turbine Lube Oil pumps will trip causing a Main Turbine Trip and a Reactor Scram.

The running Turbine Lube Oil Pumps are AC powered, not affected by loss of DC.

Response D Loss of Feedwater to the Reactor vessel due to closure of Reactor Feed pump speed governor.

Governor is electrohydraulic - oil from an AC pump, power from UPS.

Question #9 Details EQ-OP-802-2001-000-R005-001 NRC RO Retake 2003 Question Text The plant experienced a Station Blackout and all Station Air Compressors (SAC) stopped.

Instrument Air pressure has decreased to 72 psig.

Power has since been restored, and you have been directed to start the West SAC.

When the West SAC is started, it fails to load.

Why did the West SAC fail to load, and what action must be taken by procedure?

Response A Instrument Air Pressure is too high to allow loading the SAC, start the SAC with Instrument Air isolated Instrument Air should be at least 75 psig to allow loading, isolating Instrument Air would defeat the purpose.

Response B Station Air Pressure is too low to allow loading the SAC, start the East SAC Instrument Air is too low, not Station Air, and the procedure directs starting with nitrogen to increase Instrument Air Pressure.

Response C - Correct Answer Instrument Air Pressure is too low to allow loading the SAC, start the SAC using nitrogen bottles References - 1, 2 Response D Station Air Pressure is too high to allow loading the SAC, isolate Station Air from Control Air Station Air can not be too high in this application, Control Air is already automatically isolated.

Question #14 Details EQ-OP-802-3002-000-0001-011 NRC RO Retake 2003 Question Text The plant has experienced a full power ATWS The crew failed to initiate boron injection before Torus water temperature reached the BIIT.

Alternate means to shutdown the reactor have been unsuccessful.

These events could lead to exceeding the...

Response A minimum RPV flooding pressure.

Has to do with (1) the Minimum SRV Re-opening Pressure or (2) the lowest differential pressure between the RPV and the suppression chamber at which steam flow through the Minimum Number of SRVs Required for Emergency Depressurization is sufficient to remove all decay heat from the core.

Response B - Correct Answer heat capacity limit of the containment.

Reference:

ST-OP-802-3002 Response C RPV saturation limit.

The RPV Saturation Temperature is based simply on the properties of water.

Response D peak clad limit of the fuel.

The Maximum Core Uncovery Time Limit is defined to be the greatest amount of time the reactor core can remain completely uncovered and uncooled without resulting in a peak clad temperature in excess of 1500oF.

RPV level is 25" and steady on wide range Drywell pressure is 1.5 psig and slowly rising Drywell temperature is 155°F and slowly rising Which one of the following actions, if taken, will prevent drywell pressure from exceeding the high drywell pressure scram setpoint?

Response A Manually shift all dual speed drywell cooling fans to fast speed Shifting fans to fast speed will not happen because RPV level is below L1.

Response B - Correct Answer Manually start all single speed drywell cooling fans Reference ST-OP-8002-3004, 23.415 Section 5.0 Response C Manually initiate both divisions of EECW There would still only be 4 fans running in slow speed with no increased cooling of the DW.

Response D Increase EESW flow though the EECW Hx EECW has not initiated, good distractor if EECW initiation setpoints are confused.

Question #16 Details EQ-OP-315-0116-000-C013-002 NRC RO Retake 2003 Question Text What is the consequence of Torus water level dropping below -112 inches?

Response A - Correct Answer Actuation of an SRV would directly pressurize the Torus with little or no steam condensation.

Reference ST-OP-315-0016 Response B Ensure a sufficient quantity of water to prevent excessive pool swell and flooding of the downcomers during a DBA LOCA.

This is part of the basis for upper level limit for the Torus Response C Ensure a sufficient quantity of water to prevent violation of the Vortex Limit for the HPCI and/or RCIC Pumps.

Vortex Limit applies to the LPCI pumps, not HPCI and RCIC. HPCI and RCIC use NPSH limits which are based on Torus temperature.

Response D Ensure a sufficient quantity of water to prevent excessive clearing loads from SRV discharges.

3D32, Div I/II RB Vent Radn Monitor Upscale

3D36, Div I/II RB Vent Exh Radn Monitor Upscale Trip What actions must the CRNSO perform?

Response A - Correct Answer Verify Secondary Containment isolated and SGTS initiated.

Reference LP-OP-315-066, 3D36 Response B Direct a channel function test performed on all RB Vent Exhaust radiation monitors to verify readings.

Although surveys and samples would be directed, a channel function test is not performed.

Response C Declare the radiation monitors inoperable, notify Chemistry to take samples, and initiate a plant shutdown.

None of these alarms would indicate the rad monitors are inoperable.

Response D Perform an immediate plant shutdown due to loss of Secondary Containment integrity.

These are not indications of a loss of Secondary Containment.

Response A - Correct Answer Low RPV level, cavitation of the recirculation pumps

Reference:

ST-OP-315-0007, ST-OP-174 Unit 8 page 13 Response B High RPV level, exceeding core thermal limits High RPV level would cause carryover, Core thermal limits are threatened by loss of FW heating Response C High RPV level, damage to main turbine blading High RPV level would cause carryover Response D Low RPV level, neutron flux instabilities Low RPV level would cause carryunder, but the direct result would be cavitation of the recirculation pumps.

Primer circuit continuity indicators OFF

SLC pump A red light ON, green light OFF

C41 PI R600 (SLC Pump Discharge Pressure) pulsating at 1400 psig These are indications of what condition, and what should the operator do?

Response A Normal operation for the SLC System; monitor SLC Tank level.

Not normal indication -level, pressure not right.

Question #45 Details EQ-OP-315-0107-000-0006-007 NRC RO Retake 2003 Question Text A Reactor Startup is in progress. Reactor Power is currently 20%. RPV level control is currently on the Start Up Level Control Valve. At what point, and why, is Feedwater Control transferred to Single element control?

Response A At 25% power so that the Main Turbine Generator can be synchronized to the offsite grid without violating Thermal Limits.

Main Generator is synchronized earlier in startup.

Response B When feedwater temperature is within 5°F of RPV temperature to prevent power transients in the Reactor.

Feedwater temperature is never within 5°F of RPV temperature when the Mode switch is in run.

Response C Prior to placing a second Condenser pump in service due to the condensate minimum flow setting of 9000 gpm.

The second Condenser pump is placed in service prior to starting a heater feed pump.

Response D - Correct Answer When RFP suction flow is greater than 25% to prevent oscillations of the Reactor Feed Pump Minimum Flow Valve and Reactor Water Level.
