BOTH Diesel Generators have started and loads are sequencing.
The Reactor trips, but the Main Turbine does NOT automatically trip.
Steam Generator (S/G) levels quickly lower to approximately 10% before the NCO

design flow to each S/G.
B. The operator must manually initiate AFAS (Aux. Feed Actuation Signal) due to the
Loss of Offsite Power.
C. The operator must manually start AFW Pump P-8C since P-8A has failed to start on
low Steam Generator level.
D. No action is required since no power is available to motor driven AFW pumps and
the turbine driven AFW pump will deliver design flow in 92 seconds.

Q

Given the following conditions:
• Plant is at full power when a Loss of All Offsite Power occurs
• Only DIG 1-2 starts and begins load sequencing.
• Reactor trips, but the Main Turbine does NOT automatically trip.
• S/G levels quickly lower to approximately 32% before the NCO manually trips
the Main Turbine.

flow indicates 0 gpm to each S/G.
·A loss of Preferred AC Bus Y-20 occurred concurrent with the auto reactor trip.

A. No action is required, since AFW Pump P-8C will start and deliver design flow to
each S/G.
B. The operator must manually initiate AFAS (Aux. Feed Actuation Signal) due to the
Loss of Offsite Power.
C. The operator must manually start AFW Pump P-8C since P-8B has failed to start on
low S/G level.
D. No action is required since both motor driven AFW pumps cannot be started and
the turbine driven AFW pump will deliver design flow in 92 second

• P-8C is in AUTO, and not running.
• ‘A’ S/G level is 38%, ‘B’ S/G level is 26%.
Then, flow to ‘A’ S/G (via FIC-0749) is manually reduced to §ill gpm and flow to ‘B’ S/G
(via FIC-0727) is manually reduced to 95 gpm.
Which one of the following describes the expected response of AFW Pump P-8C, AND
the reason for that response?
A. Not start automatically, since P-8A is running and total AFW flow is above 165 gpm.

B.Not start automatically, since P-8A is running and both S/G levels are greater than
the AFAS setpoint.

C. Start automatically, since one S/G level is outside of the normal band.

D.Start automatically, since AFW flow is less than the minimum required.

A

D.Start automatically, since AFW flow is less than the minimum required.
