Palisades Learning Objective: TBAR_E3.01 Given plant conditions, describe the actions necessary to minimize thermal and hydraulic shock to various plant components in accordance with EOP Supplement 24

References:

EOP-3; AOP-35 Question:

The plant was operating at full power.

• At 1510 the plant tripped and offsite power was lost.

• EK-0532, BUS 1C OR 1D OVERCURRENT LOCKOUT, is lit and Bus 1D is deenergized.

• DIG 1-1 is running but its output breaker did not automatically close.

• At 1522 the transition to EOP-3.0, Station Blackout Recovery, is made.

• At 1523 an NPO was able to close the 1-1 D/G output breaker and Bus 1C is now energized.

• The sequencer did NOT operate.

• Jacket water and Lube oil temperature on both D/Gs are 105°F and rising very slowly.

What action should now be taken and why should it be done?

a. Direct the NPO to immediately trip both of the D/Gs to minimize the likelihood of damaging the D/Gs.

b. Direct the NCO to immediately start P-7B SW pump so that Maintenance of Vital Auxiliaries -Water is satisfied.

c. Close CV-1359 Non Grit SW Hdr lsol and throttle service water pump discharge valve 2 turns open then start P-7B SW pump to minimize hydraulic shock.

d. Exit EOP-3.0, Station Blackout Recovery, and immediately return to EOP-1, Standard Post-Trip Actions, to rediagnose because we no longer satisfy the entry criteria.

DISTRACTOR ANALYSIS

a. INCORRECT Plausible because neither DIG has cooling water but the given temperatures allow for the time to restore the SW before component damage occurs.

b. INCORRECT Plausible because the pump needs to be started but because 10 minutes have elapsed, damage could occur to the piping so we are instructed to take actions to prevent the resultant hydraulic shock.

c. CORRECT EOP-3.0 at step 4 directs us to restore SW cooling per AOP-35 which has these actions stipulated to prevent component damage if the loss of service water has exceeded 10 minutes which it has in this question.

d. INCORRECT Plausible since we are just entering the procedure when we have power restored but once the transition has occurred we continue in the procedure.

The plant was operating at full power when the following occurred.

• The reactor tripped due to lowering PCS pressure

• Off-site Power (LOOP) was lost concurrently

• Safety injection automatically actuated The crew has transitioned to EOP-4.0, Loss of Coolant Accident Recovery, and the following conditions are noted.

• PCS pressure is 1000 psia and rising slowly

• HPSI flow is 125 gpm per loop

• CETs are 545°F and rising slowly

• Tes are 538°F and rising slowly Based on this information, what mitigation strategy should be employed in EOP-4.0 and for what reason?

a. Raise PCS Pressure to improve natural circulation.

b. Raise steam flow to enhance natural circulation.

c. Raise PCS Pressure to improve subcooling.

d. Raise steam flow to establish subcooling.

DISTRACTOR ANALYSIS

a. INCORRECT Plausible because natural circulation flow is the desired effect but because the S/Gs are the PCS heat sink, the problem with the plant conditions is poor natural circulation which can only be corrected by adjusting the heat sink.

b. CORRECT because natural circulation cannot be established unless the S/Gs have adequate steam and feed flow. So if natural circulation is not present, that can be corrected by better control of S/Gs.

c. INCORRECT PCS pressure, and hence subcooling, is low because of the small break LOCA so this strategy will not be effective.

d. INCORRECT Plausible because the PCS is saturated so the lack of subcooling is not correctable by better control of S/Gs. While it would lower temperature, it would also lower pressure therefore the PCS would remain saturated.
