I've never seen that anyone has been able to document this claim. Meanwhile it's pretty easy to show that nuclear today is too expensive. LCoE studies shows wind power being cheaper, and attempts at building nuclear reactors in Europe has repeatedly led to economic disasters. You could argue that you could get the cost down if you make a huge push for nuclear. But the last time we did that it was a combined push for nuclear weapons and energy, which made it easier to get support and funding for education and research. Now the only major application is energy. And though you could probably get the cost down to where it was before, the cost of renewables and storage is dropping very rapidly. It seems likely that renewables will reach a price point that nuclear could never catch up to, way before the cost of nuclear will be reasonable again. And since renewables will be so cheap, most countries will want at least 50% of energy to be renewable. And that will make covering the remaining 50% with nuclear more expensive, since you'd need more advanced and expensive load balancing power plants to support the renewables. I also think that the fact that renewables give us an increasing amount of days with overproduction, i.e. extremely cheap electricity, might be a very good thing when we'll want to create more hydrogen and synthetic fuels.

> I've never seen that anyone has been able to document this claim. Are you aware that the French ministry of environment justifies closing Fessenheim because nuclear emits too much greenhouse gases ? And that some heads of EELV, the "green" french party, don't know what a life-cycle analysis is (or purposedly pretends not to know ) and asks for closing nuclear plants to be in line with the Paris 2015 climate deal ? This helps figure out how rational the current moves against nuclear are.

Without nuclear, with what life-cycle kgCO2e/kWh result, and when ?

    In a post fossil fuel economy, and assuming CO2 from concrete manufacture is captured, CO2 emissions are zero. The question of CO2 emission before then, as fossil fuels are being phased out, is less important. During that process the better question is how much CO2 emission can be avoided per $ invested. By that metric, renewables will be much better than new nuclear.
