I don’t like that Russia is using the ZNPP as more-or-less a dirty bomb threat against Europe, but at the end of the day the VVER-1000 reactors there are relatively modern GenIII pressurized water reactors. An intentional or accidental meltdown there would not create a Chernobyl-like event. It’d probably end up being more like Fukushima, which if I remember correctly lead to a couple orders of magnitude more deaths due to the stress of evacuation than it’s anticipated to create from radiation exposure.

Bottom line, when you’re talking about reactors that aren’t pants-on-head stupid designs like the RBMK the actual health risk of radiation exposure due to accident is lower than the health risks of most other forms of power, including some non-fossil-fuel alternatives. Long term storage of spent fuel is another issue, but one that’s reasonably solvable as long as we treat fission as a transitional base load power source as other alternatives like storage and/or fusion power become more viable.
