Don't confuse Fukishima with a nuclear disaster. Yes there was environmental contamination, but 10's of thousands of people were killed by a tsunami. Nuclear accidents aren't nearly that bad. What we need is more sea walls, not less nuclear plants.

Also it was of the type that melts down if the cooling water is lost. Other reactor designs (eg 3-mile island) need water to operate so they shut down automatically if there's any major breakdown.

Furthermore, coal is far more dangerous. We just don't care when thousands of Chinese coal miners die every year as much as we do when Japanese farmland is rendered unusable once in a lifetime.
