La Crosse Boiling Water Reactor
The Allis-Chalmers Company of West Allis began constructing the La Crosse Boiling Water Reactor in 1963.
On July 11, 1967, at 7:39 p.m., the reactor achieved its first sustained chain reaction, ushering both Wisconsin and cooperative electrification into the nuclear age. The reactor attained full-powered operation on August 1, 1969. After several modifications and tests, inspectors declared the reactor commercially operational on February 1, 1971, with a rated capacity of 50 megawatts.
Dairyland acquired full ownership of the facility from the AEC in August 1973, but ceased reactor operations on April 30, 1987, due to economic conditions. Dairyland currently operates a coal-fired power plant on this site.

More about this marker. This historical marker memorializing Wisconsin's entry into the nuclear age was constructed about a half a mile north of the original marker. The previous marker was located on private property of the Dairyland Power Cooperative and, due to increased security requirements of having a closed nuclear plant, was no longer accessible to the public. At the request of the Mississippi River Parkyway Commission, Dairyland paid for and installed this new marker, with updated text. The plant closed in 1987, which was not reflected in the text of the previous marker. The new marker is available to the public 24 hours a day.
