The nuclear plant in the Simpsons' hometown of Springfield is, however, a key element in the long-running show, with the hapless Homer in charge of safety despite a slapdash approach evident from the opening credits onwards.

The issue was a decisive factor Sunday in state election defeats for Merkel's conservatives in Baden-Württemberg and Rhineland-Palatinate, with the anti-nuclear Greens doubling and tripling their share of the vote respectively.
