Nuclear Facilities

Switzerland has five nuclear power plants: Beznau I & II, Mühleberg, Gösgen and Leibstadt. In addition to the nuclear power plants, three research reactors are in operation: at the Paul Scherrer Institute in Würenlingen, the Swiss Federal Institute of Technology (ETH) in Lausanne and the University of Basel. And finally, the national central interim storage facility for radioactive waste (ZWILAG) and the Federal Government interim storage facility at Würenlingen are also monitored by ENSI.
