The current state wrt to nuclear in Germany reflects a decades long consensus in Germany that spans the majority of the population, scientists, intellectuals, politicians and even energy companies.

Any opposition you do hear on this from within Germany is usually opportunistic. People are against the Greens so they just take the opposite position on their policy. A good example of this is Markus Söder (CSU) who flip flopped on this multiple times.

Realistically speaking there is no serious politician or party with a pro-nuclear position in Germany that has a plausible plan for leveraging nuclear power at meaningful scale in an economical way. Any such plan would realistically invite massive opposition because nobody wants nuclear facilities in their vicinity.
