This plant has one Combustion Engineering two-loop pressurized water reactor. The plant produces 1,240 megawatts of electricity. 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).[3] Shortly after Katrina, Waterford restarted and resumed normal operation.

During the 2011 Mississippi River floods, the plant was shut down briefly after a refueling shutdown on April 6,[4] but was restarted on May 12.[5][6]

The plant shut down on October 17, 2012, for steam-generator replacement. The plant returned to full power in the middle of January 2013.

The plant shut down on August 28, 2021 in preparation for Hurricane Ida. On August 29, 2021 the plant declared an “unusual event″ — its lowest level of emergency — after the facility lost offsite electrical power.[7]

Ownership

Waterford is operated by Entergy Nuclear and is owned by Entergy Louisiana, Inc.[2]

Surrounding population

The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.[8]

The 2010 U.S. population within 10 miles (16 km) of Waterford was 75,538, an increase of 7.4 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 miles (80 km) was 1,969,431, a decrease of 0.8 percent since 2000. Cities within 50 miles include New Orleans (33 miles to city center).[9]

Seismic risk

The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Waterford was 1 in 50,000, according to an NRC study published in August 2010.[10][11]
