The danger of nuclear isn’t so much on the daily stats of what actually went wrong, but in the tiny risk of having huge problems. The worst case scenario for a Chernobyl style disaster is actually losing huge parts of Europe. Even in well run plants, if enough things go wrong at the same time, it could still mean losing the nearest city. These “black swan” events are hard for humans to think clearly about, as we are not used to working with incredibly small chances (like deciding to plan for a 1000 year storm or not).
