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.
Today, the Federal Office of the Environment, FOEN, published its study “Extreme Flooding of the River Aare”. Their findings also include a re-evaluation of the flood risk to nuclear installations located on the Aare.
At its November 2022 plenary meeting, WENRA discussed the consequences of the current energy crisis on regulatory activities and issued a statement which highlights the importance of nuclear safety in this new challenging context.

For the second time since the Fukushima accident in 2011, power plant operators have demonstrated that their plants are capable of withstanding an extremely rare, severe earthquake.
ENSI experts gave IAEA Director General, Rafael Grossi, a guided tour of the Beznau nuclear power plant. Grossi was given a picture of the continuous improvements made to nuclear safety as laid down in the Vienna Declaration, in the setting of a Swiss example.
The Swiss Federal Nuclear Safety Inspectorate assessed the earthquake safety of the Beznau nuclear power plant in accordance with the legal requirements. The Swiss Federal Administrative Court has thus rejected an appeal lodged by 15 individuals.
Swiss nuclear power plants have an adequate level of protection against a deliberate plane crash. This is confirmed by an update of the associated analyses ordered by the Swiss Federal Nuclear Safety Inspectorate (ENSI) in 2013. For security reasons, the details are being kept under wraps.
The reactor pressure vessel is enclosed by the containment as the third barrier. This consists of a steel primary containment and a concrete secondary containment.
With its pipelines, shut-off valves and other components, the cooling circuit, together with the reactor pressure vessel, is the second barrier for trapping radioactive substances
