That's some serious cherry picking you're doing there.
It also says: "The LCOE calculations also do not capture other systemic costs or externalities beyond plant-level CO2 emissions such as, for instance, methane leakage during the extraction and transport of natural gas."
So we can just gloss over the nuclear waste problem. Which is especially interesting since the fossil plants will get a heavy hit due to their CO2 footprint.
Because of how hazardous it is, every country treats that as a national issue thus offloading the cost to taxpayers. Besides, I'm only aware of a single country (Finland I believe) who is far along on an actual permanent storage location. The US for example still doesn't have one, until that exists the real cost simply isn't known.
> And the various nuclear startups have cost projections that range from 2-3 cents to below 1 cent / kWh.
Startups have cost projections, sure. That's marketing material until they've actually built something. I'm sure SMRs will soon be reality and we can see how much of it is actually true. Until then, take everything you read with a grain of salt.
