Short term local CO2 isn’t the only environmental concern. What’s missing from these discussions is Germany’s early and extremely expensive investment in solar is a large part of why it’s become so cheap.
So it’s possible for a rational environmentalist to acknowledge the benefits and drawbacks of nuclear and decide subsidizing nuclear is a poor investment vs other options. Since 2010 Germany reduced coal production by 82 TWh while also reducing Nuclear by 104 TWh. Oil -7 TWh and gas + 6TWh effectively canceled out for a net of -83 TWh from fossil fuels.
In Germany, their actions actually caused increase in the use of coal and increased CO2 output.
