Nuclear power never became cheaper. As evidenced by it's continued languishing only supported by subsidies.
Hydro power did, and is famously called "geographically limited" because we in short order exploited near every single river globally.
France made the right choice in the 70s in the name of energy independence and nuclear weapons. They did not care the slightest about emissions.
The equivalent choice in 2024 to nuclear power in the 1970s is renewables.
"Hurr durr my cherry picked reactor!!!"
While completely ignoring all western projects. The facts are: Flamanville 3 still haven't entered commercial operation and the projected was started at about the same time as energiewende.
Flamanville, HPC, Olkiluoto 3 and Vogtle are the successful western projects. The unsuccessful get stuck in financing limbo like Sizewell C because the needed subsidies are truly stupid.

You are proposing that Germany in 2024 should have emissions closer to Poland because you value building nuclear power above curbing emissions.
Lets do a thought experiment in which renewables somehow end up being wholly incapable of solving the last 20% of carbon emissions.
Scenario one: We push renewables hard, start phasing down fossil fuels linearly 4 years from now, a high estimate on project length, and reach 80% by 2045.
The remaining 20%, we can't economically phase out (remnant peaker plants).
Scenario two: We push nuclear power hard, start phasing down fossil fuels linearly in 10 years time, a low estimate on project length and reach 100% fossil free in 2060.
Do you know what this entails in terms of cumulative emissions?
Here's the graph: https://imgur.com/wKQnVGt
The nuclear option will overtake the renewable one in 2094. It means we have 60 years to solve the last 20 percent of renewables while having emitted less.
Do you still care about our cumulative emissions when any dollar spent on nuclear power increases them?
