The combined risk of posthumanity pollution and catastrophic failures makes it a no-go for a risk averse society. Germany is spatially a comparably small country with high population density, there is not really a place where you easily can say no one lives here for the next thousands of years.

La Hague and Sellafield are or were places of necessary production chain segments with high pollution danger and history.

Zaporishja shows how dangerous centralised power production can be.

PV and wind energy were politically advocated for in Germany (California as well btw) before they were cheap and mass produced and efficient, even or especially against nuclear energy.

Austria actually is somewhat of a success story with a similar history.
