Is nuclear power safe?

Are thorium power plants safer and otherwise better?  

And how far away are we from building fusion plants?  

Just a mention; I obviously realize that there are certain risks involved, but when I ask if it's safe, I mean relative to the potentially damaging effects of other power sources, i.e. pollution, spills, environmental impact, other accidents.

Yes. There have been three major accidents in the last fifty years, and only one of them was seriously major. Compare that to fossil fuels, where, for instance, the entire gulf of Mexico gets covered in oil, or just last week when 19 miners died in a coal explosion.

We're at least 20 years from fusion plants, probably a lot more. Maybe it'll be like SimCity2000 and we'll have them by 2050.
