Swiss Federal Nuclear Safety Inspectorate ENSI
ENSI concludes that the operators complied with the licensed operating conditions in 2021 and fulfilled their legally stipulated reporting obligations. In the year under review, a total of 24 reportable events occurred at the nuclear power plants and at the Paul Scherrer Institute, all of which were assigned to level 0 of the International Event…
ENSI has included two new research projects of the Nuclear Energy Agency in its programme: one on irradiation experiments under reactor conditions, the other on long-term operational safety. In addition, ENSI has been supporting a research project on the behaviour of reinforced concrete in earthquakes since 2021, as well as two projects on nuclear waste…
All nuclear power plants were in good condition in terms of safety: this is ENSI’s assessment in its 2020 Oversight report. The number of incidents was in line with previous years. Thanks to the operators’ early precautions, the COVID-19 pandemic had no impact on the safety of the plants. Download document is in German.
The newly published Radiation Protection report 2020 shows that in the year under review there were no incidents at Swiss nuclear facilities that would have exposed their personnel or the general public to unacceptable levels of radiation. All limits for personal doses, emissions and immissions were complied with. The year 2020 was also marked by…
While some of the projects of the ENSI research programme in 2020 delivered important results and new research projects were launched, the Corona pandemic made international cooperation within the framework of committees and agreements more difficult. This is how the ENSI Research and Experience Report, which has now been published, summarises the year 2020.

This report has been corrected on 3 July 2020: 3,400 t instead of 3400 t of conventional waste and 2,935 t instead of 2935 t of radioactive material were disposed. (Chapter 2.4, page 35)
The research programme of the Swiss Federal Nuclear Safety Inspectorate ENSI has been enriched by a new topic: With the two projects HELP and DRYstars, ENSI is now exploring the long-term dry storage of spent fuel elements. More information can be found in the PDF. Download document in German
