Probably insoluble, but don't you love the attitude of people who are protesting against the cleanest and most non-polluting form of power generation, which has no significat greenhouse gas emissions "to save the planet".
What happened in Fukushima was a good recent demonstration of why nuclear power is not the solution. It having no significant greenhouse gas emissions doesn't mean it is clean or safe.
Could there ever be a time when it could be sent into space?
Wouldn't that cost a fortune?
