Thanks, informative. Hydroelectric power sounds very clean and safe, but dam failure is catastrophic.

I'm sure you're correct on the fatalities for fossil fuel vs. nuclear, but fossil fuels are also much more widely used (I imagine by several orders of magnitude).

Making land unsafe is a less dramatic aspect of safety, but actually destroying usable land is an amazing feat of destruction. I guess if reactors were located on land that was already unusable (eg. desert, esp Antarctica) it wouldn't matter so much. But I think (present-day) electrical transmission requires them to be close to the power consumers?
