Basically no one outside of china is advocating for coal use anymore, so this is a BS comparison. The much more apt comparison is against wind, solar, and storage, against which nuclear is far more dangerous. Also, it’s hard for environmental damage assessment to take into account the EXTREMELY long-lived impacts of fuel “disposal”.
This would be true, except for the fact that nuclear is terrible at filling in slack times. Nuclear power for the most part needs to run really consistently, 24/7. Better to fill gaps with a diversity of reasources, more transmission, and storage.
