Piqua Nuclear Generating Station

The Piqua Nuclear Power Facility is a decommissioned plant in Ohio, United States. The reactor structure has been fully dismantled, and today the site features only a few concrete buildings and a large, maintained area with low grass and scattered trees.

The plant was built in the early 1960s and operated from 1963 to 1966 as a test facility with a reactor that used organic fluids for cooling. After this short operating period, decommissioning began, and over several years radioactive areas were sealed and the site was secured.

The name of the plant refers to the nearby city of Piqua, a small community in Ohio. The area now uses the former buildings as storage, showing how local residents have adapted this piece of industrial heritage.

Access to the site is restricted because it remains under long-term monitoring and is not open to the public. Those interested in nuclear power history can view the surroundings from outside and learn more about the project through archives or specialized publications.

The reactor used a rare technology with organic cooling fluids, a method that was seldom applied in later plants. The output was about 45.5 MW thermal, which seems modest by today's standards but was sufficient for testing purposes at the time.
