Title	Offsite Notification Due to Intake Barrier Being Struck by Oil Tanker
Event Description	At 0835 CDT, the Entergy Transmission Operations Center notified the Waterford 3 control room that a crude oil tanker had struck the dolphins at the cooling water intake structure on the Mississippi River. There were 4 out of 5 dolphins damaged, with 3 of these having substantial damage. The dolphins are hard structures anchored around the cooling water intake structure [which provide] protection from river traffic. Waterford 3 operations was unaffected by this event and thermal power remains at 100%. The intake structure, including the Circulating Water System, was unaffected by this event. Possible near-term effects of the event are a loss of protective barrier between river traffic and the intake structure due to the physical damage to the dolphins and hazards to navigation due to the loss of the dolphin lights. At 1230 CDT, the United States Coast Guard was notified of this event in accordance with Waterford 3 procedures. This notification is subsequent to the notification of the United States Coast Guard per 10CFR50.72(b)(2)(xi). The licensee notified the NRC Resident Inspector.
