You have to do a bit more than just open the website and immediately dismiss it. Granted, it's in German, but clicking on the individual reactors gives you a list of incidents there.
If you want something more condensed, here is a list of incidents in
Germany https://de.wikipedia.org/wiki/Liste_meldepflichtiger_Ereignisse_in_deutschen_kerntechnischen_Anlagen
though also only available in German. Just because an incident does not make it to the news, does not mean that no radiation was leaked.
