Waterford Nuclear Generating Station

Waterford Nuclear Generating Station

The Waterford Steam Electric Station, Unit 3, also known as Waterford 3, is a nuclear power plant located on a 3,000-acre (1,200 ha) plot in Killona, Louisiana, in St. Charles Parish.

This plant has one Combustion Engineering two-loop pressurized water reactor. The plant produces 1,218 megawatts of electricity since the site's last refuel in October 2009. It has a dry ambient pressure containment building.

On August 28, 2005, Waterford shut down due to Hurricane Katrina approaching and declared an unusual event (the least-serious of a four-level emergency classification scale). 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 2012. 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. The project is expected to go from mid-October to early January.

    “We now recognize that abuse and neglect may be as frequent in nuclear families as love, protection, and commitment are in nonnuclear families.”

    “With boys you always know where you stand. Right in the path of a hurricane. It’s all there. The fruit flies hovering over their waste can, the hamster trying to escape to cleaner air, the bedrooms decorated in Early Bus Station Restroom.”
