Finding

Title

Licensee-Identified Violation

Description

TS 3.8.2, AC Sources Shutdown, required immediate actions to restore an EDG to operable status when the required EDG was inoperable. Contrary to this on April 24, 2010, the B EDG was made inoperable for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and 22 minutes due to surveillance testing while the A EDG was inadvertently made inoperable due to an equipment clearance from April 18, 2010 to April 26, 2010. The cause of the violation was that the licensee did not understand the equipment clearances impact on the A EDG operability. Specifically, the automatic equipment loading feature in response to a station blackout had been defeated. Manual loading of the required equipment remained functional during the event. The licensee entered the issue into the CAP as NCR 395800 and removed the clearance to restore the B EDG to operable status. The event was determined to be of very low safety significance because when the B EDG was inoperable, manual loading of the required equipment on the A EDG was available, the refueling cavity was flooded and the dedicated shutdown diesel was also available.
