OFFSITE NOTIFICATION DUE TO TEMPORARY BYPASS OF NORMAL OUTFALL DURING SEVERE WEATHER
"On January 10, 2014, Florida Power and Light reported to the Florida Department of Environmental Protection that the St. Lucie Nuclear Plant temporarily bypassed the normal storm collection outfall path at 17:45 EST on January 9, 2014. The bypassed flow of water was a result of severe rainfall at the station and a blockage in the normal outfall path.
"This non-emergency notification is being made pursuant to 10CFR50.72(b)(2)(xi) due to the notification of the Florida Department of Environmental Protection."
The licensee originally made the offsite notification to the State of Florida agency associated with the emergency declaration and severe weather event on January 9, 2014 (see Event Notification 49707).
The licensee has notified the NRC Resident Inspector.

UNUSUAL EVENT DECLARED DUE TO EXPLOSION WITHIN PROTECTED AREA BOUNDARY
The licensee declared a Notice of an Unusual Event per EAL HU2.2 "Explosion with Protected Area Boundary" following an apparent fault and explosion on the M29 transformer (a non-safety related transformer). This resulted in a loss of one electrical bus at the ocean discharge station; however, no safety-related electrical loads were effected and both units remained at 100 percent electrical power. Station personnel reported that there was no smoke in the area of the M29 transformer and the event may have been a flashover explosion in the area of the transformer. All safety systems remain available. Licensee is investigating the cause of the explosion, and no offsite assistance was required.
The licensee has notified the NRC Resident Inspector, the State of North Carolina, and other local authorities.
Notified DHS SWO, FEMA Operations Center, NICC Watch Officer, and NuclearSSA via e-mail.
* * * UPDATE ON 01/10/14 AT 2343 EST FROM MIKE MORRIS TO RYAN ALEXANDER * * *
"Notification of an Unusual Event is being terminated [at 2320 EST] because the condition no longer exists. The source of the apparent explosion was a failed insulator on a breaker and is known to present no danger to public health and safety. Both Units are stable and a recovery organization is in place."
The licensee has notified the NRC Resident Inspector regarding the termination of the event.
Notified R2DO (Hopper), NRR EO (Lubinski), IRD Manager (Gott), DHS SWO, FEMA Operations Center, NICC Watch Officer, and Nuclear SSA via e-mail.
