There was a link in this very same thread (right here) that compares France to Germany. It's a very simple case study: a country that does use nuclear pollutes 10x less per kWh than a country that actively destroyed its nuclear capability. It doesn't get any more simple than that.
Unless your argument is that if Germany didn't shut down nuclear it wouldn't have deployed renewables, which I hope it isn't because it would be a completely lunatic point to make, the situation is the same no matter how you twist the mental gymnastics. Germany's grid is one of the dirtiest in Europe largely because of the lack of nuclear baseline, which, if it was kept, would make it one of the cleanest.
If your argument is that the renewables deployed in Germany should be counted towards replacing nuclear, then you must also accept that Germany failed to significantly cut into its fossil plants with renewables, which other countries managed to do in the same timeframe, because its entire renewable capacity had to go towards filling a gap the shutdown of nuclear left. It's the same difference either way, and it suffers from the same fallacy that you're pretty clearly intentionally making at this point: that you are unwilling to consider nuclear in the context of its alternatives, and are only willing to talk about it either in a vacuum, or in an idealistic situation where renewable capacity and energy storage are high enough that shutting off nuclear will not lead to an increased demand for fossils.
I've addressed that idealistic future in this very same comment section by the way: as soon as we reach a point where we can eliminate fossils and any renewables deployed cuts into nuclear's share, as opposed to that of fossil plants, I'm against nuclear. But that's not the reality of the situation yet. The decommissioning of nuclear plants in Germany was extremely premature, and harmed the environment, both with increased radiation and with gargantuan amounts of CO2 output.
Renewables > Nuclear > Fossils. It's literally that simple. As long as we have fossils, replacing them with nuclear would be beneficial, and any decrease to nuclear capacity is a negative. If you can offset something with renewables, it should be fossils, not nuclear.
