> Nuclear power emits only a little less co2 than "clean" combined cycle nat gas when you account for the massive amount of concrete and energy for construction and decommissioning (aka lifetime emissions which is a stat rarely used for this reason).

This is far from correct. Yes, concrete production releases CO2, but that only happens once over the 50-80+ year lifetime of a nuclear power plant. Carbon emissions from nuclear are a fraction of fossil fuels [1]. They need to have a separate magnified section to meaningfully show them on the graph: https://www.carbonbrief.org/wp-content/uploads/2017/12/Scree...

And as mentioned earlier, fuels and industrial processes are where hydrogen comes into play: nuclear can produce hydrogen without C02 emissions through thermal generation.
