This Annual Report of ENSI deals solely with radiological protection in nuclear facilities in Switzerland: Section A covers both exposure rates for staff and individual job rates whereas Section B deals with releases from nuclear facilities and the monitoring of radioactivity in their immediate vicinity. Compared with previous years, there was little change in either […]
The EU stress test is part of the review process which Switzerland initiated immediately after the reactor accident in Japan. As a direct consequence to Fukushima, ENSI issued three orders to the Swiss nuclear power plants on 18 March 2011, on 1 April 2011 and on 5 May 2011, in which immediate measures and additional […]
Nine months after the disaster at the Fukushima nuclear power plant, Japan is working to contain radiation exposure in the region of the accident. The challenges confronting the country in this endeavour are shown by the new ENSI report on the radiological effects of the accident on 11 March 2011. A significant discharge of radioactivity […]
The analysis of the accidents at Fukushima confirms that Swiss nuclear plants are safe. However, the Swiss Federal Nuclear Safety Inspectorate (ENSI) has identified a variety of findings (Lessons Learned) from Fukushima which should now be utilised to continue optimising the safety of Switzerland’s nuclear power plants. All the measures that need to be implemented […]
Some initial and provisional explanations as to why the design defects came about and why the accident progressed in such a catastrophic manner are presented by the Swiss Federal Nuclear Safety Inspectorate (ENSI) in its reports which examines the circumstances before, during and after the accident. In order to understand the scope and complexity of […]
Immediately after the first live images of the accident in the Fukushima Dai-ichi nuclear power plant were broadcast all over the world on 11 March 2011, the Swiss Federal Nuclear Safety Inspectorate (ENSI) convened a group of internal experts comprising engineers, geophysicists, nuclear physicists and psychologists. A state of emergency was declared for Fukushima Dai-ichi […]
This is the 7th Annual Report of ENSI on radiological protection in Swiss nuclear facilities. Section
A deals with doses for staff and individual jobs and Section B covers releases from nuclear facilities and the monitoring of environmental radioactivity in their immediate vicinity.
Developments in the technical and legal basis of nuclear oversight: This Research and Experience Report describes and rates the findings of the regulatory research into safety, specific instructive events from nuclear facilities abroad, news regarding the international cooperation as well as current changes and developments in underlying surveillance principles. While chapters 1 to 5 target an […]
The central message of the 2011 Oversight Report of ENSI, the Swiss Federal Nuclear Safety Inspectorate is both clear and brief: There were no incidents in Swiss nuclear facilities during 2011 that could have compromised human safety.
