Reactor Containment Building at Kewaunee Power Station

Kewaunee Power Station sits on the Lake Michigan shoreline in Carlton, Wisconsin, just south of the town of Kewaunee. The single-unit pressurized water reactor began commercial operation in 1974, built and originally operated by Wisconsin Public Service Corporation. Dominion Energy later took over the plant before its owners shut it down in 2013, citing economics rather than safety concerns. The containment structure, with its rounded dome and reinforced concrete walls, housed the reactor vessel that once generated enough electricity to power hundreds of thousands of homes. In 2022, ownership transferred to NorthStar Group for decommissioning, a process that includes dismantling the reactor systems and eventually restoring the site.
