Well for one thing, there is that one obvious thing which Americans and everyone else are also unready to hear: You need to give up fossil fuels. No more coal, no more gas, no more petrol, no more diesel. Some parts of Europe like to think they're well on the way to that goal but even there for the most part you've barely begun and are moving too slowly or in the wrong direction (e.g. biofuels). The hard part cannot be put off for much longer.
Almost all of the nuclear power stations were already at the end of their lifetime anyway.
And it's much cheaper and faster to build renewable energy than nuclear, so that's what we are doing.
If you think nuclear is so great and cheap, look at france, who had to bail out the EDF (company operating all nuclear plants) because it was bankrupt. When the rivers are empty in the summer they have to shut down the plants. And a few years ago they would have had to shut down portions of the country if they hadn't got electricity from other countries because a lot of their reactors were found to have cracks in their vessels.
Shure, we Germans as a whole are still using too much fossil fuels.
But the state I live in (Schleswig-Holstein) already produces more renewable electricity than it consumes each year and I also have a lot of solar on my roof and batteries in my basement.
TLDR: Nuclear is a waste of money when renewables are so much cheaper.
