Nuclear is only so relatively expensive because it’s the only fuel source that’s forced to pay up for all the externalities up front (and I’m not saying that is a bad thing to require). A nuclear plant can’t be built if the money to make it safe (as per some specification), insure against all health complications while it’s in operation, decommission it, clean up the site, securely dump all spent fuel, and return the site back to “normal” decades later isn’t put up in escrow from the start: that’s all captured in the price.
If we did that for fossil (and other) fuels, you’d bet they would cost more too.
