It would be really, really nice if we lived in a world where people new nuclear power mostly just means heating water (like many methods of power generation…)

Yeah, heating water with radioactive material. And then having to dispose toxic byproducts that can kill millions for thousands of years.

>that can kill millions

Did the inverse square law stop working recently or do they all take turns touching it?

If nuclear power was invented today, it would have been considered a breakthrough capable of changing the course of climate change dramatically.

Air pollution from coal has many problems.

But invisibility is not one of those problems. You can see it.

I never understand why the "man in the street" with their zero knowledge will decide if which type of power plant is safe/sustainable/economical. Imagine if they would be also allowed to tell your car mechanical what is wrong and how to fix that.

That’s backwards: it actually means that protecting against nuclear hazards is astronomically expensive, that nukes are borderline unmanageable in the long term

We have had very few nuclear hazards in the past, with very limited impact as shown in this article. Nuclear plants that were really old rarely failed as well, before we added all this regulatory overhead. Weird how something "borderline unmanageable" causes way less damage than the alternatives.

Depends on if you count the $2T cleanup cost for Fukushima as limited. After Fukushima about all plants in the west had to install independent core cooling because the regulators realized the risk was systemic, even though the cause was special.

A nuclear reactor in Sweden had a severe incident in 2006 when many of the "defense in depth" layers had been accidentally removed through freak occurrences and upgrades.

It is still impossible to get private third party insurance for a nuclear plant.

The problem is perception. It has the word "nuclear" which, along with the mechanism, associates it with nuclear bombs. Not to mention, we react to large incidents with lots of fatality much more strongly than the same fatality spread out over time.

While I agree that humans are generally way too critical of nuclear power, when they seem fine with radioactive coal ash being blown into the atmosphere, measuring nuclear safety on the order of directly attributable deaths is really stupid.

And as someone already mentioned. Nuclear needs to be very reliable, because malfunctions, while they may not cause armageddon, can kill entire blocks and make the cleanup even more costly than a normal decomissioning. You absolutely want to build these things to last and be reliable. Just look at Greifswald Unit 5 partially melting down less than a month into operation. In fact, Greifswald and their numerous close calls are a great example for where "less safe nuclear" would lead us.

Earlier quoted context omitted.

it's not the irradiation that people are worried about. It's the pollution, in the litteral sense. In the case of a fire (to take an all but too common example), all the radioactive material is distributed as tiny particles that get into the air we breathe and the water we drink.

So no, they do not take turns. The live 1000 km away, and just buy a fish that swam 100 km away from the fire.

Democracy. Sounds banal, but it's all we got.

Nuclear triggers some primal fear. The safety regulations have become table stakes, unfortunately.

A comment from the author I found interesting (with some minor edits, mainly for spelling):

> "All the evacuations at Fukushima were unnecessary, and in the case of the frail [or] elderly murderously so. If there had been no evacuations, few members of the public would have received more than 1 mSv/day peak and some 1600 lives would have been saved, and some 100,000 less lives sadly disrupted. Even the EPA now counsels shelter-in-place rather than evacuation.

> At Chernobyl, it probably made sense to evacuate the 45,000 non-workers from Pripyat for a month or so. (Most of the plant workers never left. ) All the other evacuations were tragically unnecessary. The 1990 evacuations were completely senseless as is making the Exclusion Zone off-limits when the dose rates almost everywhere in the zone are below average planet wide and have been for a very long time."
