Because Germany is also where the one of the worlds first deep geological repository sites for nuclear waste was experimentally started in the 70s, in the former salt mine Asse II. That thing was supposed to last for many centuries, yet after only a few decades it became such a huge environmental mess that it will take several future generations, and a lot of money, to clean it up. Which is only one among the many reasons why nuclear fission was declared not sustainable, others include resource dependencies for the fuel and generally extremely high costs for everything, while operators refuse to pay their share for it in terms of waste disposal. All problems that "pro nuclear" people regularly handwave away, often pointing at France to go "Look, they can do it!", when that's just completely ignorant of the actual state of the French energy sector; It's existing nuclear fleet is already heavily underfunded, it's also very old, as a result of that more than half of French nuclear reactors have spent most of this summer offline. That is if they ain't throttled/shut down due to heatwaves making them impossible to cool.
