The severity of Chernobyl was greatly compounded by the fact that the Soviet government went out of their way to conceal the severity. The response to Fukushima had no such operations in place; the response was swift and well-organized and evacuations were rapid and deliberately more severe than the situation seemed to warrant. Monitoring was also used to detect elevated radioactive isotopes in drinking water and other secondary effects to prevent them from causing more widespread damage.

That said, is it your belief that if the government had taken no action to protect the civilian population, that the impact would have been similar -- "no consequences to humans" as you say? Don't confuse the severity of the scope of the accident with the casualty list; the disaster was very serious and should not be underplayed. And most of all, it should force all of us to reconsider our assessment of the potential damage that can be done by failing nuclear power plants.

You could make exactly the same argument about renewables. In terms of negative impacts they are very similar.

How much money was spent on it, building it, operating it, cleaning it up, and losing what had been invested in the region around it? How have these costs have been passed on to the Japanese population as taxes, fees, or in other ways? I don't think we'll ever know.

If you are arguing that because you missed something, then the figure is zero, I don't think that's a reasonable argument. I don't think that is what you are saying, right?

Whatever the amount is, if that same amount of money had been put into renewables, many of those people would still be living in their homes today, with sustainable power for the foreseeable future.

Sometimes, when there is a crisis as you mention, the alternatives have to be weighed against each other. Just because one alternative addresses the crisis, doesn't mean it is the best alternative. Sure, we can use both if absolutely necessary (renewables and nuclear being the alternatives we are talking about here) but it makes more sense to me to start with the sensible one, namely, renewables, and use both only if, repeating myself, absolutely necessary.

Nuclear energy is less sensible from a consumer standpoint because it is more centralized, has larger safety issues, creates more hazardous wastes, impacts property values more, raises anxiety levels more, and is more susceptible to corruption, big industry control, crony capitalism, cost overruns, and leads to huge tax increases imposed to pay for all these issues.

Even the property value impact alone should be enough for nobody to want to have a nuclear power plant in their area.

We should go as far as possible with renewables before resorting to a technology that has larger problems.
