Pre-Fukushima, most pro nuclear people would argue that the chance of a nuclear accident in an first world country was close to zero. Even I used to argue that.

Now we can say that with new safeguards of more modern reactors that the same kind of accident can't happen again, and it might very well be true. But the voting people will be less inclined to give you the benefit of the doubt. They will rather accept a known and quantified danger instead.

This is the kind of, sloppy mistakes that humans make, and aslong as humans is what keeps nuclear reactors from a disaster, I don't consider them safe, which is not to say that they aren't immensely helpful for the environment and energy production while they are in good condition. But the peoples lack of trust is warranted.
