ENSI verified the status of the Swiss nuclear power plants by 327 inspections. In 2023, the year under review, 22 reportable nuclear-safety-relevant incidents were recorded at the nuclear power plants. ENSI provides detailed information in the oversight report published today.
Both Leibstadt and Beznau nuclear power plants have shown that, in the event of or after a very severe earthquake, they can ensure that their reactors are stable and safe. Dose values of one or 100 millisievert which have to be complied with will not be exceeded even after earthquakes that are only to be…
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. The safety case for a flood caused by an earthquake has also been checked. The findings from the safety proofs generated in the aftermath of Fukushima have been…
ENSI experts gave the Head of the International Atomic Energy Agency (IAEA), Rafael Grossi, a guided tour of the Beznau nuclear power plant during a working visit to Switzerland. Grossi was given a picture of the continuous improvements made to nuclear safety as laid down in the Vienna Declaration, in the setting of the Beznau…
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.
Hans Wanner, Director General of ENSI: “Axpo has proved that the inclusions found in the steel of the reactor pressure vessel do not have a negative effect on the safety. ”
