Germanys problem is, that nuclear is supposed to be banned long before coal.
Now while I agree, that in the long term all energy should be from renewable sources, in the short term it is much more important to get those coal plants off the grid. Instead there were new ones being opened.
In the late 80s early 90s I was against nuclear power, because I saw no reason people/govt would want to off of it until the collected problems were disastrous.
In the late aughts I changed my tune because coal is just too disastrous and indeed, people/govts werent motivated enough.
So while I understand the simple practicality of going nuke to get off coal, I also expect that most of the potential downsides of nuclear will become reality before people will be motivated enough to do anything about it.
