Procedure: EOP-4.0 Question:

For a Small Break LOCA event with all equipment operating as designed, which one of the following ensures adequate heat removal from the core?

a. PCS flow out of the break with all PCPs operating.

b. Steam Generators with natural circulation flow.

c. PCS flow out of the break with 2 PCPs operating.

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.

ARP-5, window 7 Question:

Given the following with the Plant operating at full power:

A loss of all offsite power occurs Several minutes later the Control Room team notes that Lower Seal Temperature indications (on Panel C-11) for all four Primary Coolant Pumps (PCPs) are trending upward This rising seal temperature is expected because ...

a. Controlled Bleedoff from PCP seals is at a higher pressure due to isolation from the VCT.

b. Component Cooling Water is no longer circulating through the seal heat exchanger.

c. the Auxiliary Impeller is no longer providing forced flow through the seal cartridge area.

d. Increased seal leakage due to reduction in seal efficiency as pump coasts down.

DISTRACTOR ANALYSIS

a. Plausible if the student believes CBO flow is affected by the loss of all offsite power, to such an extent as to cause a rise in CBO pressure due to isolation from VCT.

b. Plausible if the student 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.

c. 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.

d. Plausible if the student believes that without power the PCP will be slowing down and VCT pressure will overcome discharge pf the Auxiliary Impeller.

Which one of the following describes what has happened and explains the above conditions?

a. RV-2006 (Letdown HX E-58 Inlet Safety Relief) lifted and continues to discharge to the Quench Tank.

b. RV-1039 (Pressurizer Safety Relief) has lifted momentarily and reseated since Quench Tank pressure is zero (0) psig.

c. RV-1039 (Pressurizer Safety Relief) lifted, remains open and the Quench Tank rupture disk has ruptured.

d. RV-1039 (Pressurizer Safety Relief) lifted and the pipe downstream of the RV ruptured immediately.

DISTRACTOR ANALYSIS

a. INCORRECT: The Letdown Relief RV-2006 lifted following CHP isolation of Letdown. Operator actions to close the Letdown orifices allow the RV to reseat. Even if the RV did not seat, following isolation of Letdown by closing the Letdown Orifices, the event would be over if this was the only reason for the loss of coolant. Also, RV-2006 cannot explain the conditions existing in Pressurizer and Reactor Head.

b. INCORRECT: PCS pressure would not continue to lower and the Reactor Head bubble would not exist if RV-1039 had only lifted momentarily and then reseated.

c. CORRECT: The Quench Tank Rupture Disk blows at 100 psig. Tank contains sufficient water volume to condense total steam mass released during a 112% to 0% reactor power swing (assumes no letdown or pressurizer spray). Normal pressure is 3 psig.

The conditions in the stem are indicative of a continuing LOCA that has not been isolated. If the leak was isolated PCS pressure would be higher riding on HPSI injection pressure.

d. INCORRECT: If the pipe downstream of RV-1039 failed immediately following the RV lift, the Quench Tank would not have ruptured as it is designed to quench the steam mass released during a 112% to 0% reactor power swing (assumes no letdown or pressurizer spray).

AOP-30 Attachment 10; AOP-30 basis document, Steps 38-47 Question:

Given:

A Plant cooldown is in progress and MODE 5 has just been entered.

The PCS is filled and intact Solid plant pressure control is being maintained using the Letdown Backpressure Regulator Then a loss of EY-01 (Instrument AC Bus) occurs unexpectedly.

Which one of the following is NOT a mitigation strategy for this event?

a. Align CV-3006, SDC Heat Exchangers E-60A/B Bypass, and CV-3025, SDC Heat Exchanger E-60A/B Outlet, for manual operation.

b. Stop all operating Charging Pumps.

c. Stop all primary Coolant Pumps.

d. Ensure PORV Block valves are closed.

DISTRACTOR ANALYSIS

a. INCORRECT, loss of EY-01 renders these two CVs inoperable electrically

b. INCORRECT, since the PCS is capable of being pressurized, CCPs are secured.

c. INCORRECT, PCPs are secured to minimize heat input to the PCS since Shutdown Cooling is lost.

d. CORRECT, strategy is that if PCS press was being controlled by Back Pressure Regulator when loss of EY-01 occurs, then consider opening PORVs to minimize cycling of Shutdown Relief Valve.
