| event text = At 2030 hours [EST] on February 14, 2013, technical specification (TS) 3.7.7 condition A was entered due to the right train of the component cooling water (CCW) system being declared inoperable. The cause of the inoperable train was the identification of an approximate 40 gallon per hour CCW system to service water system leak inside the 'A' CCW heat exchanger. TS 3.7.7 condition A requires restoration of the inoperable train within 72 hours. If the restoration is not completed within 72 hours, the plant must be in Mode 3 within 6 hours and in Mode 5 within the subsequent 36 hours. | | event text = At 2030 hours [EST] on February 14, 2013, technical specification (TS) 3.7.7 condition A was entered due to the right train of the component cooling water (CCW) system being declared inoperable.

Due to the inability to repair the leak within the required 72 hour time frame during power operation, a plant shutdown was initiated at approximately 1300 hours on February 15, 2013. Entry into Mode 3 is expected at approximately 1700 hours on February 15, 2013. The plant will enter Mode 5 to execute leak repair. Mode 5 entry is expected at approximately 0800 hours on February 16, 2013. | Due to the inability to repair the leak within the required 72 hour time frame during power operation, a plant shutdown was initiated at approximately 1300 hours on February 15, 2013.
