And what happens in the unlikely event of system collapse? If some major cataclysmic event wiped out the world economy and half the worlds population, what happens when suddenly thousands of nuclear plants are abandoned and melt down world wide? Nuclear is safer in a vacuum, but we don't exist in a vacuum. Anything that can happen, will eventually happen. Even if those power plants are able to be shut down safely, in a post stable world, the storage of the spent waste would be incredibly problematic as we would no longer have the capacity or knowledge to bury it 4 miles down. I would say that nuclear power is far more risky long term than people give it credit for. We are evaluating it's risk only based on the present stability and regulations of our current systems. Modern technological stability is really a tiny blip in earths history, we really can't guarantee a future that will know what to do with spent nuclear waste. Nuclear power is really an all-in bet on our own technological dominance of the future.

I say this as someone that is not against nuclear power, but I think people view it as some sort of quick fix when it just presents it's own problems. The truth is, you don't get something for nothing. All energy costs something and that cost should be distributed between several systems and our consumption should be reduced.
