I agree with most of what you say, but you can find reasonable attempts to calculate the carbon impact of nuclear electricity along the whole chain. As of the latest figures around a decade ago, it was in the same ballpark as solar and wind for carbon intensity, and human health impacts. https://ourworldindata.org/safest-sources-of-energy https://ourworldindata.org/safest-sources-of-energy That source has historically been very pro-nuclear, but even more critical sources don't change the fundamental conclusion too much: > Results for the process-based, input-output, and hybrid methods range between 16.55–17.69, 18.82–35.15, and 24.61–32.74 gCO2e/kWh, respectively. These are either well above or at the upper end of the range of possibilities (5 to 22 gCO2e/kWh) stated in a report for the UK’s Committee on Climate Change, and significantly higher than the median value of 12 gCO2e/kWh presented by the Intergovernmental Panel on Climate Change. https://www.sciencedirect.com/science/article/abs/pii/S0306261921002555 https://www.sciencedirect.com/science/article/abs/pii/S03062... Obviously wind and solar have improved massively since then and continue to improve while nuclear is stagnating but still the numbers suggest it's in a totally different league than fossil fuels on those metrics. It's primarily cost that makes modern renewables preferable.
