Leibstadt and Beznau nuclear power plants can withstand infrequent severe earthquakes
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…

All Swiss nuclear power plants comply with the updated earthquake safety standards
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…

The carbon content of the steam generators at Beznau and Gösgen is not too high
The steam generators at Beznau and Gösgen do not deviate from the design requirements in terms of their carbon content. This is the result of a review of the manufacturing documents. The structural integrity of the steam generators’ individual components is ensured by a large margin.

“The inspection of the steam generators of the Gösgen and Beznau Nuclear Power Plants will not require a temporary shut-down”
At the beginning of December 2016 the Swiss Federal Nuclear Safety Inspectorate (ENSI) requested the inspection of the steam generators at the Gösgen and Beznau nuclear power plants. Georg Schwarz, ENSI Deputy Director and head of the NPPs Division, explains the background and context in the following interview.

Beznau and Gösgen nuclear power plants must check their steam generators
The Swiss Federal Nuclear Safety Inspectorate (ENSI) requires that the Beznau and Gösgen nuclear power plants check the quality and design of the forgings of the steam generators in respect of adherence to the material specifications. In doing so, ENSI is reacting to information from France.
