River Bend Nuclear Generating Station is a nuclear power station on a 3,300-acre (1,300 ha) site near St. Francisville, Louisiana in West Feliciana Parish, approximately 30 miles (50 km) north of Baton Rouge. The station has one sixth generation General Electric^[2] boiling water reactor that has a nominal gross electric output of about 1010 MW_e. Commercial operation began on June 16, 1986. In 2003, owners applied and were approved for a power upgrade of approximately 52 megawatts in 2003. The nameplate capacity is 974 MW.^[3]

River Bend is operated by Entergy, which owns 100% of the station through its subsidiary, Entergy Gulf States Louisiana. The plant's operating license will expire in 2045.^[4]

The Site Vice President is Phil Hansett, the General Manager of Plant Operations is Bruce Chenard, and the Senior Operations Manager is Danny James. The station employs 870 full time employees.^[3]

Units 2 and 3

The River Bend site was originally designed to have two identical units. Construction on Unit 1 began in 1973, but Unit 2 barely broke ground, with only the containment base mat and some underground piping installed. In 1984, plans to construct Unit 2 were officially abandoned.^[5]

On September 25, 2008, Entergy filed a Combined Construction and Operating License (COL) application with the Nuclear Regulatory Commission (NRC) for Unit 3, a new nuclear reactor at River Bend. The 1550 MW_e Economic Simplified Boiling Water Reactor (ESBWR) was the selected design.^[6][7] The reactor's cost was estimated at $6.2 billion.^[8]

On January 9, 2009, Entergy indefinitely postponed work towards the license and construction of Unit 3.

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.^[10]

The 2010 U.S. population within 10 miles (16 km) of River Bend was 23,466, an increase of 11.1 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 951,103, an increase of 11.2 percent since 2000. Cities within 50 miles include Baton Rouge (25 miles to city center).^[11]

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 River Bend was 1 in 40,000, according to an NRC study published in August 2010.^[12][13]

Safety record

Unlike the Waterford Nuclear Generating Station downriver in Hahnville, River Bend continued operation throughout Hurricane Katrina in 2005. The plant was shut down during Hurricane Gustav in 2008.^[8]
