Atomkraft: Deine Entscheidung

You walk in through a protest camp. Further on sits the «Atomkraftwerk R 200», a 1960s Wilesco toy steam engine dressed up as a nuclear plant, from when atomic power still meant progress and belonged in the children's room.

The route follows the Swiss argument from the first plants through the Kaiseraugst protests, among the biggest in post-war Switzerland, to radioactive waste. Much of it comes from the anti-nuclear movement's archive of posters, stickers and photos. At five stations you mark your view on a decision card, and the walk ends in a «Kontrollraum» where everyone votes: expand or switch off. It is the one Swiss ballot that doesn't arrive in your letterbox with a booklet first.

The museum says it takes no side; the pro-nuclear Energie Club Schweiz complained that key facts were left out. The real referendum on new plants is expected in early 2027. Entry is CHF 18 (CHF 12 reduced, free under 13), with tours in German, English and French.
