The one where you couldn't safely eat anything from the Bavarian woods for a decade. And that was during years without major droughts. People are fast to forget. Nowadays loosing a harvest to a nuclear plume during a drought would be devastating.

Also, even the nuclear plants near the coast are often shut down during the summer. E.g. France's Gravelines was running only half it's generators due to jellyfish nearly shutting down the cooling system (at least) the second year in a row.

And we mustn't compare it with the ecological impact of using gas in a democracy instead of nuclear under a communist regime
