More people die every single year from radiation in coal than have died in the entire history of nuclear power. Replacing all coal with nuclear would save more lives and health than fighting nuclear ever could, even in theory.
And delaying coal to nuclear under the banner of "wind and solar maybe one day can help a bit" has blood on its hands.
Every year coal is still here, instead of nuclear, is 100 years of death. If building powerplants (of any type) were instant, and solar were one year away, then we should STILL replace all coal with nuclear TODAY, to minimize harm. (in a spherical chickens in a vacuum sort of way)
And not only do we not have enough solar, we don't even have a plan for energy storage for solar and wind. We have ideas, not a plan.
So solar&wind replacing coal&nuclear is further away than fusion power, by multiples.
