> share the opinion that the standard that nuclear is held to is higher than it needs to be — on the basis of the old "deaths per TWh" chart

And if you ignore possible deaths from Chernobyl, how about the purely financial cost?

Current $/MWh prices are high enough that, given current LiIon prices (and that LiIon is what we get even if we don't put in any effort to get cheaper alternatives given its widespread usage), I recommend people stop trying to make it happen and put their efforts elsewhere.

But my claim is, if Chernobyl hadn't Chernobyled, the $/MWh price would probably be lower.

I'm not making a specific claim that it would be cheap enough, though; I don't have enough relevant background to guess the magnitude.

You seemed to be saying that the standards nuclear is held to is higher than is necessary. Compared to what? Was my question. I asked about the cost of Chernobyl, from https://en.wikipedia.org/wiki/List_of_disasters_by_cost

$790 billion at 2021 cost

so my point was perhaps it is being held to a higher standard for a very good reason.

(NB. I'm not automatically against nuclear power, but I seriously question their potential cost against their very definite benefits. We had one Chernobyl, I guarantee we'll have another in time. Question is, how hard are we prepared to work to push that possibility, statistically speaking, as far into the future as possible)

Sure, it's a perfectly reasonable question and I ought to have justified it better.

Ok, so, total energy produced to by all nuclear reactors in the world in 2021 was apparently 2,653,344 GWh[0]; if there was a Chernobyl-scale disaster every year, that would add just under $0.30/kWh to the cost of electricity[1]. As reactors didn't have such a poor MTBF even then, I think a decade is a less unreasonable guess for rate of exploding, which is 3¢/kWh.

This may seem too concerned with dollars and not enough with lives, but similar things can be said in favour of lives cost per unit of energy produced, and again that's in favour of a yearly Chrenobly over all the fossil fuels, though not the renewables: https://ourworldindata.org/grapher/death-rates-from-energy-p... (I remember an older version that had much worse PV death rate, justified on the grounds installing stuff on rooftops is dangerous).

Like most arguments in favour of nuclear, it's more about the world we used to live in than the one we now live in; if you'd asked me 10-15 years ago, I'd have been all-in on nuclear to save the planet, but now, I think we have better options. But these were my reasons for being pro-nuclear at the time.

A commendable answer, thanks. The issue of lives I skipped as the deaths from chernobyl were counted in wiki as 60 to 60,000. Can't really conclude much from an error bar of 3 orders of magnitude.
