Thanks for the shoutout - I am interested in the answer, so I've done some cursory searching and I found this Dutch paper. This was the backbone to a public debate some years ago on whether The Netherlands should go all for nuclear energy as a main source of energy. It's issued by the government and answers a very interesting question: how much would it cost for an investor per kWh to produce energy, on a national scale, over 30 years of use? They compare nuclear, wind and biomass with coal and gas energy production and also calculate how much more expensive it would be if the CO2 from coal and gas were captured at 20 to 50 euros per tonne CO2. It doesn't give an exact number; rather, the study looks at a priceband. This is not because of all externalities, but it accounts for construction and operational risks and future price changes. See it as the range of prices to base a business case on. I translated the resulting graph: So it can be lower, although the priceband shares half of its range with regular coal and gasification. They have this to say on externalities: That is surprisingly low, especially since CO2 storage adds about 1 to 2 cents per kWh with regular coal. I don't know if that covers all externalities you are interested in, but it's better than nothing. I also found this Wiki page. It goes in-depth on the Levelized Cost of Electricity, LCOE, which is the cost of capital (buildings & equipment), maintenance and fuel divided by the amount of energy produced over its lifetime. It does not include taxes and subsidies. It's based on this research paper, and has this graph for Germany in 2013: If you look at the history of U.S. projections, you can see that coal is now around 20% cheaper than nuclear and 4 times as cheap as solar. The projection for 2020 is that coal and nuclear will be the same price, but that solar will have gone from 4 times as expensive to just a bit more expensive than coal - dropping 68% over 5 years. As you said, it's only a matter of time. I'm not sure if this is enough of an answer - if anyone knows more about this stuff, feel free to chip in. flagamuffin?
Large-scale electricity production can create external costs and benefits. [...] Examples of this are damages to health because of air pollution, costs of climate change and the certainty of energy demand. [...] A study by Bollen en Eerens (2007) calculated the health benefits of cleaner air and reduced CO2 impact when choosing nuclear over coal to be around 0.5 eurocents per kWh.
