Palisades Nuclear Generating Station
The Palisades Power Plant is a nuclear power plant located on Lake Michigan, in Van Buren County's Covert Township, Michigan on a site of 432 acres (2 km²) 5 miles south of South Haven, Michigan, USA. Palisades is owned and operated by Entergy. It was operated by the Nuclear Management Company and owned by CMS Energy Corporation prior to the sale completed on April 11, 2007. It was built at a cost of $149 million. Its single Combustion Engineering pressurized water reactor weighs 425 tons and has steel walls 8 + 1 â„ 2 inches (220 mm) thick. The containment building is 116 feet (35 m) in diameter and 189 feet (58 m) tall, including the dome. Its concrete walls are 3 + 1 â„ 2 feet (1.1 m) thick with a 1 â„ 4 -inch-thick (6.4 mm) steel liner plate. The dome roof is 3 feet (0.91 m) thick. Access is via a personnel lock measuring 3 feet 6 inches (1.07 m) by 7 feet 8 inches (2.34 m). The Westinghouse Electric Company turbine generator can produce 725,000 kilowatts of electricity. It first generated electricity December 31, 1971. On July 12, 2006 it was announced that the plant would be sold to Entergy. On April 11, 2007, the plant was sold to Entergy for $380 million. The plant's original licensee was due to expire on March 24, 2011. An application for 20-year extension was filed in 2005 with the Nuclear Regulatory Commission. It was granted on January 18, 2007.

Spent fuel storage
Spent fuel rods are stored outdoors in nine 16-foot-tall (4.9 m) storage casks, each containing 30 tons and resting on a concrete pad. This was intended to be a temporary solution until the spent fuel repository at Yucca Mountain nuclear waste repository opened. However, the Yucca Mountain site is no longer considered an option for storing reactor waste.

Parts replacement
Two faulty steam generators were replaced in 1992. This involved cutting a 28 by 26 foot opening through the 3.5-foot-thick (1.1 m) reinforced concrete wall. The removed units are buried in a large concrete bunker on plant property. The reactor head was due to be replaced during a refueling outage. Babcock and Wilcox Canada started to fabricate a new reactor head in 2005 but the project was canceled about one third of the way in. The head and other components now sit in storage at a Westinghouse facility. Currently there are no plans for replacement of the reactor head at Palisades.

Like all U.S. Nuclear Power plants since September 11, 2001, public access to Palisades is prohibited. However, a good view of Palisades can be glimpsed from the neighboring Van Buren State Park.
