approaching and declared an unusual event. Shortly after Katrina, Waterford restarted and now is in normal operation.
Entergy is planning to replace the unit's two steam generators as well as the reactor vessel closure head and control element drive mechanisms during a refueling outage in 2011. The project is estimated to cost $511 million. The steam generators are being replaced due to normal wear and tear on the equipment. Waterford 3 is one of the last units in its class to replace its steam generators. Entergy petitioned the Louisiana Public Service Commission on June 27, 2008 for approval of the project.
