We are very sorry but all our free guided tours have been reserved.

Our free guided tours

Our nuclear power plant is very popular. This is why we offer
free guided tours in german language to interested visitors every Friday. Unfortunately, these tours are usually reserved rather quickly.

As we strive to offer our free guided tours to as many visitors as possible, tour dates may be reserved in blocks for longer periods of time.

These tours are conducted in German.

If you have any questions, please do not hesitate to contact us at
