Ok, let's do a Fermi-like estimation. Estimates on the number of deaths related to coal generation vary from around 13,00 to 30,000 per year in the US [1] and 500,000 per year in China [2]. The current world population is 7.6 billion, of which the US and China account for approximately 1.8 billion people. Let's round the coal-related death rate way down for easy math: 10,000 per year in the US and 100,000 per year in China. Then, multiply that rate by the world's population, and you have, let's say 450,000 coal-related deaths per year worldwide. This is a really squishy number, but we only need approximations here. You were concerned about how many people would die every hundred years from nuclear disasters, so let's see if we can work today's 450,000 per year estimated deaths backwards for the last hundred years. The world population was somewhere in the neighborhood of 1.8 billion people in 1917. Assuming linear growth (I know, I know) and a strong r-value correlation for population vs. coal-related deaths (arguable, but again, Fermi estimate), we have to sum .00006 * population from 1.8 billion -> 7.6 billion, and we end up with approximately 28 million people. Which is to say, if we could gather up all the deaths, worldwide, from coal, over the last hundred years, and convert it into a single disaster, it would kill the entire city of Shanghai, and New York for the apple on top. That would have to be one hell of a nuclear disaster. Now, there are arguments to be made that the energy we've received from coal has also powered hospitals and technology which have saved or improved people's lives. There are also arguments to be made that the side-effects of coal (hospitalization, environmental disasters) cause the death toll to absolutely pale by comparison. And again, I've rounded these numbers down at every stage of the calculation.

[pdf]; it includes its own numbers, at the 13,000 estimate, and the EPA's, at 14,000 to 36,000 range.

There are very few people who are anti-nuclear power who are pro-coal. Even ignoring renewables, gas solves many of the worst problems with coal.

  Sure, but even natural gas and rooftop solar have higher rates of death per year than nuclear. (In my second link above.) In a world in which we must choose the lesser of evils for energy, nuclear is among the least evils, yet faces the greatest overall public resistance to new installations.

    I dunno - even that source itself says that the death rates from solar would fall using better construction methods. It also notes (in the case of wind) that increased take up is associated with lower death rates ("Wind power proponent and author Paul Gipe estimated in Wind Energy Comes of Age that the mortality rate for wind power from 1980–1994 was 0.4 deaths per terawatt-hour. Paul Gipe’s estimate as of end 2000 was 0.15 deaths per TWh, a decline attributed to greater total cumulative generation.") I'd also note that the very low rates of death from nuclear power do not appear to include construction deaths, which are the only source of death measured from wind and solar.

    >even natural gas and rooftop solar have higher rates of death per year than nuclear. the difference here is that no event can significantly change the death rate from gas or solar whereis one wrong cough by nuclear power plant worker and we have Chernobyl with thousands of deaths (in particular in Belarus which took the majority of the Chernobyl hit - about 5000 extra thyroid cancer cases (normally a rare cancer) in the people who were children at the time plus doubling (and in some areas tripling) of the rate of the most frequent cancer - breast cancer (typically 1 in 7 women would get it during lifetime, so doubling means additional 15% of all the women in the affected area would get it) in the areas close to Chernobyl like the Gomel and Mogilev regions plus very significant increase in other frequent cancers of internal organs like colon,etc.) Or counting it the other way - Russia and Ukraine both have the same - 0.0034 - incidence rate of cancer per year (despite the war and economic differences it is the same people with the same behavior/habits :), while Belarus where people are basically the same as in Ukraine and Russia and drink and smoke and eat the same - has 0.0052 incidence rate, ie. 50000 new cases per year instead of 34000 if they were to have the same incidence as Russia and Ukraine. 16000 extra cancer cases per year for several decades with mortality higher than 50% ... >nuclear is among the least evils, hardly so, giving the numbers i referenced above (compare it to coal - the coal's 700K/year deaths means "only" 1K/year for Belarus) and potential of any nuclear power plant to repeat Chernobyl - i'm aware about technical improvements of modern reactors, yet "stupidity will find a way"... > yet faces the greatest overall public resistance to new installations. still wondering why ? :)

Is that 0.04 deaths/TWh sourced anywhere? I've seen it before, but trying to trace it down is... troubling. There's this report[1], where they only count accidents where more than 5 people were killed. This coincidentally manages to avoid counting all accidents in nuclear plants, where in the US alone there were 8 deaths[2]. I assume other energy sources would see a jump too, but that doesn't give me great confidence. The number from that report is different anwyay.
