After the events in Fukushima Daiichi, ENSI ordered immediate actions and additional safety tests for the Swiss nuclear power plants. Moreover, from the accident analysis and the EU stress test, ENSI derived a need for action to improve nuclear safety in Switzerland: the “Fukushima Action Plan”.
Today, the Federal Office of the Environment, FOEN, published its study “Extreme Flooding of the River Aare”. Their findings also include a re-evaluation of the flood risk to nuclear installations located on the Aare.
The tests at the time confirmed that, in international comparison, Swiss nuclear power plants have a high safety level. Despite these learnings, it is important to remain attentive at all times, to keep the proofs of safety up to date, to live a strong safety culture and to systematically analyse events.
Oskar Grözinger has spent most of his working life in nuclear regulation. During the EU stress test, the physicist was deputy chairman of the “Topic 1 – External Influences” division. As team leader of the review experts, he has participated in inspections in the Netherlands, Slovakia and Spain and supervised peer reviews in Taiwan, Armenia […]
Jukka Laaksonen was Chairman of the Western European Nuclear Regulators Association (WENRA) and Director General of the finnish nuclear safety authority Säteilyturvakeskuksen (STUK) when the events in Fukushima took place.

After the nuclear accident in Fukushima Daiichi, extrapolations revealed that about one-eighth of the amount of radioactivity that escaped at Chernobyl was released into the surrounding area.
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.
Ten years ago, a very strong earthquake and the subsequent tsunami destroyed the Fukushima-Daiichi Nuclear Power Plant (NPP). Safety systems failed and in several reactor units, the result was a core meltdown and the release of considerable quantities of radioactive substances.
