My understanding is that the radiation problem in Germany is since Chernobyl...
I don't think people's viewpoint on this issue has anything to do with nationality.
> if the waste is dealt with properly and stored safely
At least in Germany, nobody figured out yet how to store the waste properly for a long-time. Remember, that the country is densely populated. For example, take a look at the Asse II mine.
There's a world outside Germany. Pay someone outside Germany to deal with it.
The thing is: No matter how often it is repeated, there is currently no safe place to store a sufficient volume of nuclear waste securely anywhere in the world. It's not just a simple question of "paying someone else".
Developing those sites seems possible but the solution to the waste problem isn't there yet.
It didn't fly well with either public opinions, though.
Using those sites for commercial waste is not allowed anymore since 2005 though.
And how is that going ? Not good.
The biggest problem with nuclear waste that everyone keeps overlooking is the potent NIMBY issue. In democracies politicians need to do what their constituents want in order to survive. And constituents will forever be scared to the bone about nuclear waste anywhere near them.
