Those reactors were ancient and, even without the nuclear power phaseout, they would’ve needed to be replaced.

Would the timeline have been the same?

The choice was build wind turbines and solar panels and upgrade the grid or spend the same amount of money on building nuclear reactors that still rely on imported fuel that needs to be mined in some third world country in an extremely environmentally destructive way

Solar panels at least use a lot of imported materials from what I’ve read. So similar issues there. Not sure which ends up as the lesser evil for the third world.
