surly the solution is green energy sources and cutback on energy consumption and not nuclear.

Because

1. it takes 10-20 years to build a nuclear powerplant, so it doesnt solve anything today.
2. it cant be run profitable unless the taxpayer pays for the construction and the deconstruction and the disposal of the waste,
3. it needs a huge amount of river water for cooling which is not safe for climate catastrophe, because the rivers dry up at least temporarily, e.g. france

I don't think that it's safe. I do think having sixteen intermediate storage facilities on the surface with high level nuclear waste is a massive security concern that we should address immediately. As long as we don't have a long term solution in Germany, we should not produce more nuclear waste. That's why it has been such a long running open question: https://en.m.wikipedia.org/wiki/High-level_radioactive_waste_management
