Germany Spent Billions on a Nuclear Plant That Never Split a Single Atom — Now It's a Theme Park

West Germany built an entire nuclear reactor — and then decided never to switch it on. This is the story of the fast breeder reactor at Kalkar: a billion-dollar German megaproject that was fully completed in the nineteen eighties, never loaded with nuclear fuel, never started, and eventually turned into a family theme park with a swing ride inside its cooling tower. We trace how the most expensive nuclear plant that never went nuclear came to be — the breeder dream, the public revolt, the runaway costs, and the political decision after Chernobyl that left a finished reactor standing dark forever.
