In my opinion, we need loads of additional nuclear power plants everywhere. And keep them to a high standard, unlike Fukushima which wasn't up to safety standards.
While this Fukushima accident might affect a few lives in the local area, it's nothing compared to how many people are killed by coal power plants each day. That smoke is the worst imaginable for the environment, and it's very carcinogenic too.
I'm not going to fearmonger though, I like to stick with the facts. NPP's have a history of being generally clean and able to supply a lot of power. CPP's still supply most of the worlds electricity. I just don't think renewable energy has any possibility of replacing coal in the near future. Nuclear power does.
