SNR-300, Nuclear power plant in Kalkar, Germany.
SNR-300 is a nuclear facility in Kalkar featuring a sodium-cooled fast breeder reactor designed to produce 327 megawatts of electricity. The plant was constructed but never operated commercially and now serves a different purpose.
Construction of this facility began in 1972 as a joint project of Germany, Belgium, and the Netherlands, with completion in 1985. After the 1986 Chernobyl accident, operation was blocked and the plant never became operational.
Following the 1986 Chernobyl incident, public concerns regarding nuclear energy safety led to increased opposition against the SNR-300 operation.
The site is now open to the public and transformed into Wunderland Kalkar, an entertainment park with attractions housed in the former reactor buildings. Visitors should know that the site can be explored on their own or with guided tours, with varying activities depending on the season.
The project cost approximately 7 billion Deutsche Mark, making it one of the most expensive abandoned nuclear plants in Europe. The site today stands as an example of how massive industrial infrastructure can be repurposed for an entirely different use.
