2024 Operating Report: Nuclear installations met safety requirements
Over the past year, nuclear installations in Switzerland fulfilled the requirements for safe operation. This is the conclusion reached by the Swiss Federal Nuclear Safety Inspectorate (ENSI) in its initial operating report for the 2024 oversight year. Both the public and the environment were protected from radioactive substances.

Gösgen nuclear power plant can withstand category 3 earthquakes
The Gösgen nuclear power plant has demonstrated that it can bring its reactor to a safe and stable state in the event of or after a very severe earthquake. For earthquakes that are only expected to occur every 10,000 years, the permissible dose of 100 millisievert will not be exceeded. However, ENSI is requesting the…

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…
