Which of the following is NOT a required contingency action if a Diesel Generator will be
inoperable greater than 72 hours?
A. The GTGs must be started and parallelled to the affected Diesel Generator emergency bus.
B. No discretionary maintenance activities will be scheduled on the gas turbine generators (GTGs).
C. The GTGs will not be used for non-safety functions (i.e., power peaking to the grid).
D. The functionality of the GTGs will be verified by ensuring that the monthly start test has been successfully completed within the previous four weeks before entering the extended DG Completion Time.
A. The GTGs must be started and parallelled to the affected Diesel Generator emergency bus.
• The plant is at 100% power.
• The Crew is presently in 3.8.1 condition A due to a loss of an off-site circuit.
• All actions in 3.8.1 condition A. have been completed.
• 4 Hours later the AO reports the associated circuit Emergency Diesel Generator (EDG) lube
oil indicates 0.5 inches in the site-glass.
Based on these conditions, the crew should declare the EDG inoperable…
A. 48 hours after time of discovery.
B. and enter the required actions 3.8.2.
C. and enter the required actions of 3.8.1 condition b and d.
D. and enter the required actions of 3.8.1 condition d and 3.8.2 actions a and b.
C. and enter the required actions of 3.8.1 condition b and d.
• Unit is operating at rated power.
• One Diesel Generator becomes inoperable.
Which one of the following Tech Spec actions must be completed within one hour?
A. Restore DG to operable status.
B. Determine that the opposite train DG is not inoperable due to a common mode failure.
C. Verify correct breaker alignment and indicated power availability for two offsite power sources.
D. Declare required feature(s) supported by DG inoperable when its redundant required feature(s) is inoperable.
C. Verify correct breaker alignment and indicated power availability for two offsite power sources.
- Unit one is at 100% power
- DG A Train B starting air receiver fails to 0 psig
What action is required?
No action required. Bases says only 1 starting air receiver is required for operability.
Technical Specification 3.9.4 (SDC and Coolant Circulation) requires ONE train of Shutdown Cooling to be OPERABLE and in operation. However, this LCO is modified with a note that permits the Operating Crew to deviate from this requirement. Correctly complete the below sentence with the information contained in the note.
Provided no operations are permitted that would cause reduction of the Reactor Coolant System boron concentration, the required SDC loop may be removed from operation…
A. for ≤ 1 hour per 8 hour period.
B. for ≤ 1 hour per 24 hour period.
C. for ≤ 8 hours per 24 hour period.
D. until RCS temperature reaches 180°F.
A. for ≤ 1 hour per 8 hour period.
