EOP-1.0 Basis; EOP-2.0 Basis Question:
EOP-1.0, Standard Post-Trip Actions, and EOP-2.0, "Reactor Trip Recovery," contain guidance regarding operation of the feedwater system. What is the guidance given, and why is it important?
- a. Raise feedwater flow using Main Feed Pump speed controllers to compensate for the rapid lowering of S/G levels (shrink effect) after the trip. This aids in maintaining TAVE at less than 540° F.
- b. Manually lower feedwater flow using Main Feed Pump speed controllers to prevent over-feeding the S/Gs. This action avoids unnecessary cycling of ESS equipment.
- c. Trip both Main Feed Pumps to compensate for the rapid rise in S/G levels (swell effect) after the trip. Manually start one Auxiliary Feedwater Pump to provide finer control and aid in maintaining TAVE greater than 525° F.
- d. Manually lower feedwater flow using Main Feed Pump speed controllers to prevent over-feeding the S/Gs. This action helps prevent feedwater isolation due to feed regulating valve high level override.
DISTRACTOR ANALYSIS
- a.
INCORRECT - Plausible if the student incorrectly believes that feed rate needs to be raised to compensate for the shrink effect of the trip.
- b.
CORRECT - Per EOP-1.0 immediate action #3
- c.
INCORRECT - Plausible if the student confuses shrink and swell effects from up powers and down powers.

GFES lesson plan - Steam Question:
A Pressurizer code safety valve has indications of leakage. The following indications are noted:
Pressurizer pressure is 2060 psia and stable.
Pressurizer Vapor Space is 640°F and stable.
Safety Valve tailpipe temperature indicates approximately 230°F and rising slowly.
Quench Tank pressure is 6 psig and rising 1 psi every 10 minutes.
Which one of the following is the reason for the lower temperature indication seen downstream of the safety valve?
- a. The leak is too small to overcome ambient heat loss to the containment.
- b. The fluid temperature downstream of the safety valve lowers because a large amount of energy is lost in the throttling process.
- c. The fluid temperature corresponds to the Quench Tank saturation pressure because minimal energy is lost in a throttling process.
- d. The volume of water in the Quench Tank quenches the superheated vapor downstream of the leaking safety valve.
DISTRACTOR ANALYSIS
- a.
INCORRECT - Plausible if the student incorrectly believes that the heat is transferred to the containment due to the sizing of the pipe and the transport time
- b.
INCORRECT - Plausible if the student believes that a significant amount of energy is lost across the safety valve seat.
- c.
CORRECT - A constant enthalpy process means same BTU/LBM of fluid. Using mollier diagram, go to the new pressure (Quench Tank) directly to the right on a constant enthalpy line. Follow the pressure line up to the saturation curve to determine the temperature of the fluid.
- d.
INCORRECT - Plausible if the student believes that the steam downstream of the safety valve becomes super-heated and is condensed by the relatively cool water in the quench tank.

For a Small Break LOCA event with all equipment operating as designed, which one of the following ensures adequate heat removal from the core?
- b. Steam Generators.
- d. Safety Injection flow.
DISTRACTOR ANALYSIS
- a.
Related to a common misconception regarding the reason for trip two, leave two strategy. Here the candidate misapplies it, and mistakenly believes that forced circulation forces more coolant out of the break and therefore provides more cooling. PCPs actually add heat to the PCS when running.
- b.
CORRECT
- c.
Candidate again misapplies the trip two/leave two strategy. Here the candidate believes that core heat is being removed via forced circulation but the heat input from the PCPs is not as high as with all 4 PCPs in service.
- d.
Safety Injection flow does provide some cooling, but the definition of a small break LOCA inherently implies minimal SI flow, due to the slow pressure reduction of the PCS, and therefore minimal cooling from SI flow.

- a. PCS loop Delta T and Core Exit Thermocouples.
- b. Tcolds and Thots.
- c. PCS loop Delta T, and Tcolds.
- d. Core Exit Thermocouples and Thots.
DISTRACTOR ANALYSIS
- a.
INCORRECT - CETs is correct, however PCS loop Delta T is not. Plausible because loop delta T could be an accurate indication of PCS heat removal for single phase natural circulation, however, for a large break LOCA, two phase natural circulation cooling is complex enough that loop delta T is not meaningful.
- b.
INCORRECT - Plausible for the same reason as loop delta T
- c.
INCORRECT - Plausible if the student believes that the two phase natural circulation process for a Large Break LOCA utilizes flow past the S/G U tubes and back to the core via the cold legs. This could be a process during a large break LOCA, but there may also be two phase reflux natural circulation cooling occurring which would render cold leg temperature not meaningful.

From full power a Loss of All Offsite Power occurs. All other equipment functions as designed.
Several minutes later the NCO-Turbine notes that Lower Seal Temperature indications (on Panel C-11) for all four Primary Coolant Pumps (PCPs) starts trending upward. This rising temperature is expected because...
- a.
the Seal Impeller is no longer providing forced flow through the seal cartridge area.
- b.
the Piggyback impeller is no longer providing forced flow through the seal cartridge area.
- c.
Component Cooling Water is no longer circulating through the seal heat exchanger.
- d.
Controlled Bleedoff flow from PCP seals is now at a lower flow rate.
DISTRACTOR ANALYSIS
- a.
CORRECT - PCS coolant flowing into the seal cavity is forced by the Seal impeller (also called Recirculation or auxiliary impeller) through the integral heat exchanger where it is cooled to approximately 130°F.
- b.
Candidate misunderstands the function of the Piggyback impeller, which actually is mounted on top of the main pump impeller and provides forced circulation for the hydrostatic bearing.
- c.
Candidate incorrectly believes that CCW is isolated when the pump loses power. When the loss of all offsite power occurs, there is initially a load shed of the busses which power the CCW pumps. But as the EDGs start and load, two CCW pumps will be sequenced on and continue to provide CCW flow through the seal heat exchanger.
- d.
Candidate incorrectly believes CBO flow is affected by the loss of all offsite power, to such an extent as to cause a rise in seal temperature indications.

DBD-1.04, p. 78, SOP-2A, 7.3.1.b, CAUTION prior to step, DBD-2.04, p. 61 Question:
With the plant at 60% power, a loss of all charging flow occurs. Why is it important to maintain the secondary plant (main steam flow) as stable as possible until the problem has been corrected?
- a. With the Pressurizer level now reducing at 44 gpm, a load rejection transient would accelerate the level reduction.
- b. VCT level will lower to the point where explosive hydrogen is released if main steam flow rises.
- c. Letdown temperature will damage the purification demineralizer resins if a load rejection occurs.
- d. With the Pressurizer level now reducing at 4 gpm, a rise in main steam flow will accelerate the level reduction.
DISTRACTOR ANALYSIS
- a.
Incorrect, since letdown will automatically isolate (via TICA-0201) as a result of high letdown temperature, which will result from the loss of charging flow through the Regenerative Heat Exchanger. Also, a reduction in steam flow results in expansion of the primary coolant and a rise in PZR level.
- b.
Incorrect, VCT level will actually RISE at ~ 4gpm (PCP seal controlled bleedoff flow); letdown has isolated on high temperature since there is no charging flow (cooling) through the Regenerative Heat Exchanger. Candidate correctly diagnoses that a rise in main steam flow would result in a lower PZR level (shrinkage), but misapplies it in relation to the VCT level.
- c.
Incorrect, since the letdown temperature sensing point (TICA-0201) which causes isolation of letdown is UPstream of the CCW - cooled letdown heat exchanger. The protection for the demineralizer resins is from a sensing point DOWNstream of this heat exchanger.

- b. Start P-67B, and then stop P-67A.
DISTRACTOR ANALYSIS
- a.
INCORRECT - plausible if the student incorrectly believes that starting a different LPSI pump will restore SDC flow to above the limit.
- b.
INCORRECT - plausible if the student incorrectly believes that starting a different LPSI pump will restore SDC flow to above the limit and an interruption in SDC flow is not desired.
- c.
INCORRECT - plausible because throttling CV-3025 closed will help to minimize cavitation and flow fluctuation, however, this is not a desirable action because CV-3006 (SDC HX Bypass) works with CV-3025 (SDC HX Outlet) to control SDC temperature.

- d. Close CV-0944A, CCW to Spent Fuel Pool & Radwaste Evaps, and close MV-CC184, SFP HX's, RW EVAPs, & C-54 CCW Return.
DISTRACTOR ANALYSIS
- a.
INCORRECT - Plausible if the student believes that the CCW surge tank is not receiving enough makeup water from T-81, PMU Tank. However, T-2 recirc pump cannot develop the head to force flow to the CCW surge tank which is on the 649 level. This will not help restore surge tank level to enable restart of the pump.
- b.
INCORRECT - Plausible because CV-0944 will isolate RW Evaps and C-54 but will not isolate the SFP HXs. This will not isolate the leak
- c.
INCORRECT - Plausible because CV-0944 will isolate RW Evaps and C-54 and CV-0977B is the return for RW Evaps and C-54 cooling water. This will not isolate the leak.

For which type of Anticipated Transient Without Scram event will P-55A, Charging Pump, speed controller (SIC-0216) output signal be expected to move in the MAXIMUM output direction, prior to any operator action?
- a. Loss of Load.
- b. Containment High Pressure.
- c. Steam Generator Low Pressure.
- d. Pressurizer Low Pressure (TM/LP).
DISTRACTOR ANALYSIS
- a.
CORRECT - If the reactor should have tripped on a Loss of Load, but did not, PCS heat removal is not occurring.
PCS inventory will expand as indicated on a rising Pressurizer level. The Pressurizer Level Control Program will attempt to maintain Pressurizer level by reducing the speed of P-55A variable speed charging pump (controller output moves toward maximum).
- b.
Whether the containment high pressure condition has resulted from a Main Steam Line Break, or from a LOCA, the effect is the same on the PCS - a large amount of heat and/or inventory is being removed. Pressurizer level will lower rapidly. The PLCS program will attempt to maintain pressurizer level by raising the speed of P-55A (controller output goes to minimum).
- c.
Steam Generator Low Pressure results in a rapid removal of heat from the PCS. The effect will be shrinkage of PCS inventory, lowering Pressurizer level, and a rising speed of P-55A (controller output moves toward minimum.)
- d.
A Pressurizer low pressure condition results from an overcooling of the PCS. This overcooling will cause shrinkage of PCS inventory, with resulting PLCS control signals to P-55A variable speed charging pump to add inventory. P-55A speed controller will reduce output to accomplish this (i.e., controller output will move toward the minimum direction).

CORRECT
- b.
INCORRECT - Plausible if the student believes that the generator cannot self-excite.
- c.
INCORRECT - Plausible if the student believes the load will be dropped causing the diesel to trip on overspeed.

Question:
The plant is at 80% during a power ascension when the following alarm annunciates:
EK-1347, "CONTAINMENT AIR COOLERS SERV WATER LEAK" The operator then takes all required Operator Actions of the alarm response procedure to attempt to isolate the leak. After these actions are complete, it is noted that the alarm had NOT cleared.
Based on the above actions, which one of the following describes the location and minimum flow rate of the leak?
- a. The leak is NOT on a Containment Air Cooler and has a flow rate of at least 700 gpm.
- b. The leak is on ONE Containment Air Cooler and has a flow rate of at least 300 gpm.
- c. The leak is on ONE Containment Air Cooler and has a flow rate of at least 700 gpm.
- d. The leak is NOT on a Containment Air Cooler and has a flow rate of at least 300 gpm.
DISTRACTOR ANALYSIS
- a.
INCORRECT - The fact that the leak in NOT on a CAC is correct, however, the alarm initiates at 300 gpm for a service water leak. This is plausible if the student does not know the setpoint for the CAC service water leak alarm, i.e., the student should know that 10% of total containment service water flow from a leak should not be the setpoint.
- b.
INCORRECT - Plausible if the student does not know that each CAC inlet is cycled one at a time to see if the alarm clears.
- c.
INCORRECT - Plausible if the student does not understand that each CAC inlet is cycled to check to see if the alarm clears and if the student does not know the setpoint for the CAC service water leak alarm, i.e., the student should know that 10% of total containment service water flow from a leak should not be the setpoint.

The following valid alarms annunciate:
EK-1101, CONTAINMENT INSTR AIR LO PRESS EK-1102, INSTRUMENT AIR LO PRESS Several seconds later, EK-1103, SERVICE AIR LO PRESS annunciates.
Additional conditions:
Instrument Air header pressure (as indicated on PIA-1210) has stabilized at 82 psig.
ONLY C-2A is running. C-2B and C-2C are NOT running.
Local pressure indication for all three Instrument Air Receiver Tanks has stabilized at approximately 105 psig.
No manual operator action has been taken.
What is occurring, and what is the effect on plant equipment?
- a. An air leak on the Service Air system DOWNstream of Service Air header isolation CV-1212; the Cooling Tower Pumps trip on low makeup basin level signal.
- b. High differential pressure on the in-service Instrument Air post-filter (F-5A/B); Track Alley/VRS sprinkler systems actuate.
- c. A leak on the Instrument Air system UPstream of the Instrument Air Dryer; Main Transformer deluge system actuates.
- d. Instrument Air Dryer temperature at 300°F; various air operated control valves throughout the plant will begin spuriously changing position.
DISTRACTOR ANALYSIS
- a.
INCORRECT - If the leak is on service air system, containment and instrument air low pressure alarms would not come in and the standby air compressors would start. This is plausible if the student believes that the leak is large enough to affect the containment and instrument air systems.
- b.
CORRECT - this is the only possible choice that would cause service air isolation and the standby instrument air compressors to not start.

INCORRECT - CV-3006 fails open on loss of air. Plausible because when the plant is on SDC, CV-3006 and CV-3025 (SDC HX outlet) are throttled for temperature control.
- c.
CORRECT
- d.
INCORRECT - CV-3006 fails open on loss of operating air. This is plausible because during a RAS, maximum cooling is desired via the SDC heat exchangers to cool the containment.

Given the following conditions:
Boric Acid Storage Tank, T-53A, level is 94%.
An Auxiliary Operator has been designated as the Boric Acid batcher, and has a mixed batch of Boric Acid (T-77, Boric Acid Batch Tank, is full) ready to release to T-53A.
Which one of the following describes how the shift must control and monitor this evolution?
- a. The AO should release all the contents of T-77 to T-53A in order to ensure T-53A level is above the low alarm setpoint. The AO notifies the Control Room when the transfer is complete so that Chemistry sampling can be requested.
- b. To prevent overflowing T-53A, the NCO and AO should discuss in advance on how much of T-77 should be released. The AO monitors T-53A level from the batching room and terminates the batch when T-53A level indicates 100%.
- c. No transfer of T-77 to T-53A may occur since T-53A level is already at its high level alarm setpoint.
- d. Since there is no level indication for T-53A in the batching room, the AO must maintain close communication with the NCO. Only part of T-77 may be released to T-53A, in order to avoid a nuisance high level alarm for T-53A.

SOP-2A, 7.8.1, and 7.8.3 f. 1 Question:
Which one of the following describes operational aspects of PCS hydrogen removal using mechanical degasification during a cooldown in preparation for a Refueling Outage?
- a. PCS subcooling is maintained LOW to enhance hydrogen removal, and is terminated when PCS hydrogen is < 5 cc/kg if chemical degasification is not to be performed.
- b. Used only when the plant is in MODE 3, and requires a minimum of four VCT nitrogen purges to prevent a flammable gas mixture.
- c. Requires single charging and letdown in order to avoid excessive hydrogen in the VCT, and is terminated when VCT hydrogen is < 5% if chemical degasification is not to be performed.
- d. Used only when PZR bubble is collapsed and requires Containment Vent Header Isolation Valves CV-1101 and CV-1102 be open to prevent hydrogen buildup in containment.
DISTRACTOR ANALYSIS
- a.
CORRECT - Low PCS subcooling (low pressure) brings more hydrogen out of solution, and is therefore more effective (SOP-2A, 7.8.3.f). A PCS hydrogen concentration of < 5 cc/kg is considered as a successful degas (COP-1, Attachment 1, section 6.0).
- b.
Candidate misapplies mode restrictions for mechanical degas. This method of degas can be performed in MODE
- 1. There are numerous places throughout Palisades' procedures which specify number of purges required for the VCT. Candidate recalls the requirement for a plant startup from a Chemistry procedure (COP-1, Attachment 9, 1.2) and misapplies it here.
- c.
Per SOP-2A, 7.8.3.g, maximum letdown enhances the process. Single charging and letdown is NOT required, nor desired. Candidate fails to recognize the parameter used for recognition of a successful degas (i.e., PCS hydrogen, not VCT hydrogen).
- d.
One aspect of Chemical Degas is adding hydrogen peroxide. A prerequisite to this is ensuring PZR bubble has collapsed (COP-1, Attachment 13, 3.3). Candidate recalls this fact correctly; however, Containment Vent Header Isolation valves cannot be open during this evolution (SOP-2A, 7.4.1.g).

- a. Will auto start. Verify P-52C discharge pressure >115 psig.
- b. Will auto start. Check for excessive loading on D/G 1-1.
- c. Will NOT auto start. Manually start P-52C and ensure acceptable loading on D/G 1-1.
- d. Will NOT auto start. Reduce CCW loads to avoid a runout condition on P-52A.
DISTRACTOR ANALYSIS
- a.
INCORRECT - P-52C will not auto start. Plausible if the student believes that the DBA sequencer start signal and the low pressure signal do not need to be present at the same time. 115 psig is the discharge pressure limit for 2 pump operation per SOP-16.

- c. Approximately 10 minutes after Recirculation Actuation Signal occurs pump seal failure is expected to occur.
- d. Cannot be operated since Service Water backup cooling is not available.
DISTRACTOR ANALYSIS
- a.
Candidate fails to recognize that once RAS occurs, the CSS pumps will be taking suction on the containment sump, with water temperatures exceeding 325° F. There is a common misconception that these pumps can operated indefinitely without cooling water, when the vendor has specified a limiting time at maximum temperature.
- b.
Candidate misapplies knowledge of the effects of SIAS, and believes that reduced cooling occurs.
- c.
CORRECT - Once RAS occurs (and it will, for a Large Break LOCA), the CSS pumps suction source is now in excess of 325° F. Per the seal manufacturer, life of the seals at this temperature is reduced to only 10 minutes.
- d.
Candidate misapplies knowledge of the sequence of a Large Break LOCA (i.e., it will be some period of time before RAS occurs). Until then, the CSS pumps are taking suction from the relatively cool water in the SIRW tank.

Main Turbine vibration rises rapidly due to several turbine blades puncturing the turbine casing.
A rapid complete loss of Main Condenser vacuum occurs.
The Turbine NCO verifies the Main Turbine has tripped.
The Reactor FAILS to trip automatically or manually.
The crew takes appropriate actions for reactivity control, and reactor power is lowering.
The Atmospheric Dump Valves FAIL to actuate.
What is the effect of the above conditions on the plant secondary system?
- a. Main Steam Safety Valves operate to maintain secondary system pressure at less than 110%
of design pressure.
- b. Turbine Bypass Valve operates to maintain secondary system pressure at less than design pressure.
- c. Main Steam Isolation Valves close to prevent excessive depressurization of the Steam Generators.
- d. Steam Generator Hi-Level Override actuates to prevent water damage to Main Steam lines.
DISTRACTOR ANALYSIS
- a.
CORRECT
- b.
INCORRECT - Plausible if the candidate fails to apply knowledge that a complete loss of vacuum disables the TBV.
- c.
INCORRECT - MSIVs would not receive a close signal for these conditions. Plausible, since there was a turbine trip. Candidate misapplies relationship between MSIVs close signal and turbine trip signal.
- d.
INCORRECT - Plausible if the candidate misapplies the response of "shrink" and "swell"; incorrectly thinking that a sudden stopping of steam flow results in a "swell" effect on indicated S/G level. Also, it is a common misconception that the purpose of S/G Hi-Level Override is to protect the Main Steam Lines from structural failure due to the weight of being filled with water; when in reality, the purpose is to prevent damage to the Main Turbine due to water carryover.

- c. They will experience excessive vibration due to cavitation at the pump suction.
- d. The pump turbines ramp down to minimum speed to prevent overfeeding Steam Generators.
DISTRACTOR ANALYSIS
- a.
CORRECT - At full power, even one condensate pump tripping would cause such a severe reduction in MFW Pump suction pressure that BOTH MFW pps would trip on low suction pressure.
- b.
INCORRECT - Correctly believes feed pumps trip, but for wrong reason.
- c.
INCORRECT - The protective low suction pressure trip actuates long before any cavitation would develop.
- d.
INCORRECT - There is a certain plant condition that causes MFW pumps to ramp down in speed, but it is incorrectly applied here.
