Niederaichbach Nuclear Power Plant was a German nuclear plant in Niederaichbach, Bavaria. The plant consisted of one heavy water gas cooled (HWGC) reactor with a gross capacity of 106 MWe. Safety and maintenance issues caused the reactor to be decommissioned after only a year and a half in operation. It was the first nuclear plant in Europe to be completely decommissioned, with the final work being completed in autumn 1995.
