APTIM provides best-in-class maintenance, modification, and construction services to Entergy at the Waterford Steam Electric Station, Unit 3, also known as Waterford 3, a nuclear power plant located on a 3,000-acre plot in St. Charles Parish, Killona, Louisiana. The station is a one-unit, Westinghouse pressurized water reactor site, which produces 1,185 MW of electricity.  In 2012, Waterford 3 underwent a steam generator replacement project. The project was one of many that will enable the plant’s 1,159 dependable megawatts of electricity to continue supplying approximately 10 percent of the state’s needs.
