The decommissioned nuclear power plant Kewaunee ( English Kewaunee Nuclear Generating Station , abbreviation KNPP ) in Carlton, Wisconsin on Lake Michigan , about 35 miles southeast of Green Bay , 18 miles from Two Rivers and nine miles south of Kewaunee . is located on a 900 acre power plant approximately three miles north of the Point Beach Nuclear Power Plant . Therefore, the management of the facility was consolidated with the blocks in Point Beach.
The reactor
The power plant consists of a pressurized water reactor with a net electrical output of 556 MWe and a gross output of 581 MWe. By May 7, 2013, around 140,000 US apartments were supplied with electricity from the nuclear power plant. The nuclear steam generator system comes from Westinghouse .
history
Construction of the Kewaunee nuclear power plant began on August 6, 1968. On April 8, 1974, the reactor was first synchronized with the power grid and had been in commercial operation since June 16, 1974. The Kewaunee Nuclear Power Plant was the fourth nuclear power plant to be built in Wisconsin and the 44th in the United States. The plant received perfect marks in the evaluation process of the Nuclear Regulatory Commission in 1989 and 1995. Until 2000, the plant ran for 511 days without being shut down since the last fuel element change ; in 1999 it ran every 365 days without a break. In 2004 the capacity factor of the plant was 81.8%. On February 21, 2005 the reactor was shut down due to a design flaw in the auxiliary feed water system. The plant was restarted in July after the Nuclear Regulatory Commission confirmed that the fault had been properly resolved.
In July 2005, Dominion Resources acquired the power plant from previous owners, Wisconsin Public Service Corporation and Alliant Energy . The Virginia-based company also owns the North Anna , Surry, and Millstone nuclear power plants . In North Anna and Surry the licenses were renewed in 2003, in Millstone in 2005. On December 21, 2013 the license for the Kewaunee nuclear power plant expired. However, the licensee filed an application with the Nuclear Regulatory Commission on August 14, 2008 to extend the license until December 21, 2033.
On October 22, 2012, the operator announced that it would shut down and dismantle the power plant in the 2nd quarter of 2013 for economic reasons. Since April 2011 the owner Dominion Resources tried unsuccessfully to find a buyer for the nuclear power plant.
Shutdown
On May 7, 2013, the power plant was shut down and finally disconnected from the power grid. After Dominion was unable to acquire any other power plants in the region, Kewaunee became uneconomical for the energy company. A sale to other companies failed, although the operating license for the power plant was extended by the Nuclear Regulatory Commission for 20 years. The power plant is to be completely dismantled; according to the operator, sufficient funds are available for this.
