KEWAUNEE COUNTY (WLUK) – A “major licensing action for new nuclear generation” at the former Kewaunee Power Station site is expected to be filed soon, according to the company which owns the site.
The Kewaunee Power Station sits on the shores of Lake Michigan in the town of Carlton, between Kewaunee and Two Rivers. It first began operations in 1974 and the plant was formally closed in May 2013.
The site is now owned by EnergySolutions. The company has said it is exploring the option of building an integral molten salt reactor there.
In a recent news release, EnergySolutions said it filed a ‘notice of intent’ with the federal U.S. Nuclear Regulatory Commission confirming plans to submit an application for the site.
“A structured, multi-phase project is being carried out that includes initial planning and scoping activities. In-depth studies are being conducted that will support the application to demonstrate the site’s suitability for new nuclear construction. This is a prerequisite to the development and securing of NRC approvals for this project,” the news release states.
“This is an important milestone in moving towards the next generation of nuclear power in Wisconsin in partnership with WEC Energy Group.” said Ken Robuck, President and CEO of EnergySolutions. “As communicated when we announced this initiative in May of 2025, the need for reliable, carbon-free power has never been greater. We have assembled an experienced team that brings environmental compliance, nuclear licensing and project management expertise to this project at a time new nuclear generation in Wisconsin is essential.”
The nuclear power plant won’t be fully decommissioned until at least 2031.
