Personally I'm not worried about the biggest nuclear accident so far. I'm worried about the potential future very unlikely but very severe nuclear accident that kills a non-negligible fraction of the population. An accident that makes Chernobyl look small.

This needs to be balanced with any loss of life from global warming. Some would want to consider non-human life in that calculation, as well.

(I don't know enough about this to know if nuclear will have a large impact, in the grand scheme).

Sure, it's a risk vs reward thing and my comment was just focusing on the risk - a risk that I think is continually downplayed because we are bad at appreciating the costs of extremely unlikely but extremely bad events that have never occurred before.

If the reward is high enough the risk might be justified. Personally I doubt it (mostly because economically solar + wind + power storage seems like a better bet), but that's a whole other discussion.
