> they are quite optimistic about nuclear power

Centrifuge enrichment and improved extraction techniques (high quality ore in Canada or else in-situ leaching) mean CO2 emissions are very low.

Would you care to provide references for CO2 emissions from already built nuclear power stations (preferably not the infamous StormSmith and Sovacool papers)?

For new-build, Hinkley Point C "not an EPD" make interesting bed-time reading. https://www.edfenergy.com/sites/default/files/hpc_-_life_cyc...
