This is completely untrue. The Atomaustieg happened under Merkel (CDU) and was catalyzed by Fukushima. That's democracy, for you, btw.

The current energy "crisis" was due to idiotic trust (CDU/SPD) in Russia's goodwill and consequently opting for huge structural natural gas dependency. Foreign energy dependency wouldn't change with with nuclear power, since uranium isn't mined in Germany. Russia actually is a major uranium exporter (btw still supplying the US). Uranium mines are a horrible dirty shit show, western nations tend to outsource...

Another grave mistake was discontinuing the funding/support of renewable energy industry and research, where Germany was leading once. Now, China rules in solar manufacturing. Germany still got game for wind energy, tho.

Germany does not have a need for "base load" nuclear power plants, we need a substitute for gas power plants, which can be easily turned on/off as needed. Factually, no one in the energy industry in Germany wants to go nuclear, again. It's just not economical, sensible (as for time scales) or overall competitive with renewables (unless less regulated/dangerous, enormously substituted).

Overall, we got mostly off Russian gas dependency exceptionally well and quick, all things considered, because of pragmatic green politics at the time (Habeck's image suffered because of deliberate smear campaigns, not because of severe factual failings). Lights stayed on, things kept moving, under downright hostile conditions. Renewable energy is booming. You see solar everywhere, no matter the political alignment.

Considering the real threat of war with Russia, distributed renewables are an invaluable asset. Try bombing wind power or solar... gonna get expensive. Many houses here are becoming quasi autarkic for heating, electricity and mobility, due to household solar panels, heat pumps, energy storage in electric cars and dedicated batteries. A central multi-GW nuclear power plant is a huge liability for national security, especially, since Germany is existentially dependent on the French and UK strategic nuclear deterrent. (US not reliable/trustworthy anymore.)

The only sensible reason to build reactors in Germany would be breading/enriching weapons-grade fission material, for self-sufficient nuclear defense... Which I don't see happening really.
