I agree that renewables are a very good alternative to nuclear power, but in practice moving away from nuclear means doubling down on coal. The problems with nuclear are political, but the alternatives to nuclear power are mired in political conflict as well.

As for your dam bursting scenario, something like that actually happened in the 70s when the Banqiao Dam burst. Nearly 200.000 people died. Fukushima had 0 radiation deaths.

You can't really say 0 deaths, because no one knows. We don't have good epidemiological models for wide-spread low-level dispersal such as was seen at Fukushima, we already know incidences of cancer and gene mutation don't scale linearly with exposure at low levels. There are also associated deaths from psychological factors of those who were evacuated, lost land / business etc. which will only become apparent in years to come.

Dams do have the potential for massive loss of life as you say, and they also suffer from the problem of massive centralisation of capacity (unlike e.g. solar or wind). On the smaller upside, the models related to fatalities are pretty well understood.

Perhaps an instant move away from nuclear may need coal, although here in the UK it's gas that has been taking up the slack while the government dilly-dally on whether to build out new nuclear or invest in renewables research (successfully doing neither).

I see over the longer term renewables coming up as nuclear is naturally retired at the end of the current plant's lifespan. Solar is now cheaper than coal to built-out in many places, there are other impediments but (generally) lack of public support isn't one of them (compared to coal/nuclear).

Deaths resulting from psychological factors involving those who were evacuated count when it comes to nuclear energy but not when it comes to dam failures? I don't think this kind of double standard is reasonable.

Besides, I'm pretty sure you just copied the argument about low level exposure from the Fukushima disaster wikipedia page, but you conveniently left out the next sentence: "given the uncertain health effects of low-dose radiation, cancer deaths cannot be ruled out.[11] However, no discernible increase in the rate of cancer deaths is expected."

Scare-mongering about nuclear radiation doesn't help anybody but the coal and gas industry.

I never said that such deaths form dam failures didn't count. The only reference I made to dams is that the model (physically traumatic & psych-related death) is well understood. Deaths due to low-level, widely dispersed radiation is not.

I'm afraid you were wrong to be "pretty sure" that I copied the argument from Wikipedia, I haven't read that page (until you pointed it out now). My comment comes from what I've picked up working for 10 years in epidemiology at Oxford. I didn't "conveniently" leave out the next sentence, and I wouldn't have quoted it anyway as its effectively tosh. There is no discernible increase expected on current models, but the current models are accepted (by most experts) not be useful predictors, as described in my initial post.

It's not "scare-mongering", it's being open to scientific discussion and exploration. Blind-adherence to your view-point doesn't help anyone but the nuclear industry.

Let's have open and honest debate. Even when that means we say "we don't know".

> Fukushima had 0 radiation deaths.

I think making that statement or even the comparison to other types of disasters is a little disingenuous. With most disasters they happen and then they're over in very short order. A nuclear disaster is very slow to unfold and the deaths from radiation related illnesses are not yet fully realized for quite some time.

The Chernobyl disaster is still unfolding and even with the latest containment, NSC, having been installed. It will take hundreds of years before we're done with it.

> in practice moving away from nuclear means doubling down on coal

Is it not possible for us to build out renewable energy on a large scale? My impression was that we're reaching points where it's very cost effective to do so.
