This failed $5.3 billion nuclear power plant in Germany is now an amusement park

The SNR-300 was supposed to be Germany's first fast breeder nuclear reactor when construction began in 1972. The reactor was made to use plutonium as fuel, and it would output 327 megawatts of energy.

Built in Kalkar, the government had some concerns about the safety of the nuclear reactor, which delayed construction. The power plant was
finished in 1985 — $5.3 billion later.

But after the Chernobyl disaster in 1986, the SNR-300 never got a chance to fully operate, and by 1991 the project was officially canceled. This left the power plant completely unused, and it was eventually sold to a Dutch investor who decided to turn it into an amusement park: Wunderland Kalkar.

The total size of the amusement park is 136 acres, the size of 80 football fields.

There are a total of 40 attractions throughout the amusement park, including a log ride similar to the popular Splash Mountain at Disneyland.

A swing ride was built inside of the cooling tower.

People who visit the amusement park are completely safe from radiation because the power plant never actually went into production.

The amusement park also has a 450-room hotel for guests to stay at during their visit, with several restaurants and bars.
