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 [https://www.nrc.gov/about-nrc/emerg-preparedness/about-emerg-preparedness/emerg-classification.html 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 power plant, which is located about {{convert|25|mi|km}} west of New Orleans, was restarted on May 12,[4][5] after a refueling shutdown on April 6.[6] The plant also shut down on October 17, 2012, for steam-generator replacement. The plant returned to full power in the middle of January 2013. OwnershipWaterford is operated by Entergy Nuclear and is owned by Entergy Louisiana, Inc.[2] Surrounding populationThe Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of {{convert|10|mi}}, concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about {{convert|50|mi}}, concerned primarily with ingestion of food and liquid contaminated by radioactivity.[7] The 2010 U.S. population within {{convert|10|mi}} 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 {{convert|50|mi}} was 1,969,431, a decrease of 0.8 percent since 2000. Cities within 50 miles include New Orleans (33 miles to city center).[8] Seismic riskThe 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.[9][10] See also{{stack|{{Portal|Louisiana|Energy|Nuclear technology}}}}
