Whatever estimates the nuclear power industry made in Germany, they're argued to be insufficient, so they're capping the upper liability limit for these companies. The government's own stress testing suggests there will be a shortfall that'll ultimately be picked up by taxpayers. https://www.cleanenergywire.org/news/german-utilities-buy-ou...

How about the mess that long term storage in Germany is in ?

The salt mine Assen that they put some nuclear waste in is now flooded. Getting the nuclear waste back out will cost several billions. I don't think they will even do it. So they risk contaminating ground water. That alone can be a cost of several billion.

And even if they do clean it up they are back to square zero in their quest for long term storage.

Truth is that no one really knows. Deep storage is one alternative, but 100.000 years is a long commitment. Breed reactors might reduce that to 1000 years, but it's still a commitment.

You're citing a self-interested source. That's a nuclear industry trade association. Sort of like asking the Tobacco Industry Association about the healthfulness of cigarettes.
