The issue with the nuclear power is the nuclear warhead. Mankind would be perfectly fine with nuclear power but will always be at risk as long as it is weaponized. Some folks being fatally radiated does not impose risk to our kind.
That is generalisable to all global catastrophic risk: by virtue of the fact that they can occur once, and once only, means that we're effectively living in the survivorship-bias universe in which they did not occur.
That thought's only recently occurred to me, though Richard Posner wrote of it.

By definition, all but the last doomsday prediction is false. Yet it does not follow, as many seem to think, that all doomsday predictions must be false; what follow is only that all such predictions but one are false.
-Richard A. Posner, Catastrophe: Risk and Response, p. 13.
