They are just too expensive to run up and down with demand resulting in less than 50% duty cycle.
So the idea of wildly increasing the contribution of nuclear to our total energy production is at face value fallacious. We might be able to reach 40% of our peak generation capacity. I checked the data for the region including Pennsylvania and the max usage was around 140 GW and the minimum was about 73 GW, that's 2:1. Trying to use nuclear for even half that supply would be risky since it would mean finding a way to dump a lot power should something go offline. But then nuke plants are inherently inefficient dumping twice the amount of heat as they turn into electricity, so maybe it wouldn't be a big deal to dump 100%. Just very expensive.
So while we could increase our reliance on nuclear power, we can't solve the carbon problem with it. I suppose we could connect massive amounts of energy storage and add even further to the already high cost of nuclear.

BS. If CO2 is going to screw the world, is already creating weather
calamities like the proponents claim, them we should be going all out
on nuclear right now. Nuclear generates 20% of US power. Solar, after
all the talk and two decades of doing, generates 1.6%. Those are the facts.
