It's not nuclear power that scares me, it's the seemingly inevitability of incompetence of human beings. I am a very big advocate of nuclear power, and the Japanese are a very pre-prepared culture, yet this got way out of hand.

Yes it was a huge and unprecedented earthquake, but in my opinion, there were so many totally unnecessary failures, even under these extreme circumstances, that I'm a lot more leery of nuclear power than I was before. Or, to be more precise: I'm not leery of nuclear power itself, but of humans ability to form societies advanced enough to harness this power properly.
