More people died from the Fukushima area evacuations than the meltdown.
It's pretty much impossible to get an exact pulse on how many people died indirectly as a result of the Fukushima Daiichi disaster evacuation specifically who would've lived if it were not for that. Particularly because most of the deaths attributed to the disaster were elderly to begin with.
Not trying to downplay the cost of human life, it's really terrible when preventable scenarios or mistakes lead to any cost. With that having been said, there are sometimes going to be events where evacuations are necessary, and some of them we can't prevent. No doubt there were many thousands of deaths unrelated to Fukushima Daiichi due to the massive earthquake and tsunami.
I believe it is estimated that around 1,000-2,000 people died as part of the evacuation efforts, but I am not sure what a good source is, so take that with a grain of salt. If you want to go really deep, it'd be wise to consider the burden that it may have caused psychologically too, but that's even harder to exactly ascertain, especially since it is likely nothing compared to what happened as a result of the earthquake and tsunami.
If the point of this is to compare safety though, factoring this in still would place nuclear fission power plants very low in terms of how much cost of human life they cause overall.
And yet, despite that, it is in fact possible to make nuclear fission power plants survive this kind of disaster, and especially possible to prevent the meltdown that eventually occurred; Fukushima Daiichi is not the only fission plant in Japan, and not the closest to the epicenter of the disaster either. I think it's fair to say given the evidence that the problems that need to be solved with regards to Fukushima Daiichi are the systemic issues that led to the inadequate safety measures and the unfortunate decisions made leading up to the meltdown. Whether the issues be operational complacency, corruption, etc.
It'd be nice to have a way to simply be robust to those issues, but in the end it's always going to be dangerous to human life if the people in charge of decisions that could endanger human life are not adequately responsible. That would still be the case in absence of nuclear power, natural disasters, evacuations, etc.
I'd be getting my family the flying f outta there. Not logically deducing outcomes and risk factors on HN.
Hindsight is 20 20...
E.g. due to propaganda, people thought that Covid is 100x as deadly as it actually is (people estimated on average that infection fatality rate was 10%, when in reality it’s ~ 0.1%)
Applies both to Fukushima and Covid response.
