Kewaunee was a 570 MW pressurized water reactor located on the shores of Lake Michigan in northeast Wisconsin. Plant construction began in 1968 and the plant began licensed operations in 1974. In 2012, and citing economic pressures, the plant owners announced that Kewaunee would cease operations the following year. On May 7, 2013, the plant permanently came offline.


2017 saw the completion of spent fuel movement from the fuel pool to dry storage. The plant has been placed in SAFSTOR status with decommissioning operations slated to begin in 2069.


The Kewaunee nuclear power plant is located within Kewaunee County, Wisconsin. As of 2016, socioeconomic information is as follows:

  • Population: 20,000
  • Per Capita Annual Income: $45,000
  • Unemployment rate (not seasonally adjusted): 3.1%

Kewaunee provided its 500 employees, with some of the highest paying jobs in Kewaunee County, with many earning double the per capita income of $42,152 for 2014. The Town of Carlton received nearly $400,000 annually in lieu of taxes, based on the electrical capacity of the plant and nuclear fuel storage.
