Q

AFA-P01 is aligned and ready.
All maintenance activities have been completed, as have all applicable Surveillance Requirements, with the exception of SRs 3.7.5.2, 3.7.5.3, and 3.7.5.4, due to the fact that testing can only be accomplished once temperature reaches 532°F.

AFA-P01 is considered operable because:

A) SR 3.0.4 allows this condition until steam pressure is >800 psi.
B) SR 3.0.1 allows this condition until steam pressure is >500 psi.
C) SR 3.0.4 allows this condition.
D) SR 3.0.1 allows this condition.

A

D) SR 3.0.1 allows this condition.

Q

SR 3.7.11.1 Operate each CREFS train for 15 minutes.
SURVEILLANCE FREQUENCY 31 days

It has been determined that this SR was missed for the Train A CREFS during the month of April.
Because of this, the SR has NOT been performed for 58 days.
A risk evaluation has determined that the ST cannot be performed within the 24 hours of the discovery of the missed SR and needs to be delayed to the longest extent possible.

What is the crew required to do?

A) Declare the CREFS Train inoperable, perform the SR within 4 days of the point of discovery.
B) The CREFS Train remains operable, perform the SR within 31 days of the point of discovery.
C) Declare the CREFS Train inoperable, perform the SR within 31 days of the point of discovery.
D) The CREFS Train remains operable, perform the SR within 4 days of the point of discovery.

A

B) The CREFS Train remains operable, perform the SR within 31 days of the point of discovery.

Q

Tech. Spec. Surveillance Requirement 3.5.5 requires the RWT boron concentration to be verified every 7 days in modes 1 through 4. Assume it has been 8 days since the RWT boron concentration has been verified while the plant is in mode 1. What is the status of the RWT?

A) Inoperable because the 24 hour delay period of SR 3.0.3 has been exceeded.
B) Inoperable because the surveillance interval of Tech. Spec. 3.0.3 was exceeded.
C) Operable because a 25% extension of the surveillance interval is allowed by SR 3.0.2.
D) Operable because the surveillance requirement only needs to be done once within 7 days of entering mode 1.

A

C) Operable because a 25% extension of the surveillance interval is allowed by SR 3.0.2.
