After the accident in the Japanese nuclear power plant Fukushima Daiichi, stress tests were carried out in all European member states operating nuclear power plants, in Switzerland and in Ukraine. This was followed by a peer review process coordinated by the European Nuclear Safety Regulators Group (ENSREG).
ENSREG adopted an action plan based on these reviews. Member states then drew up national action plans and discussed them in April 2013. It was recommended that the national action plans be updated regularly by the national nuclear regulators. The aim of this process was to have the participating countries agree on a widely harmonised level of risk reduction regarding extreme events in nuclear power plants while maintaining their national responsibility for nuclear safety. In the competent European bodies the Federal Environment Ministry is calling for such joint discussion and review processes among European partners to be intensified and continued on a permanent basis.
To follow up on implementation, updated national action plans were published in 2015 and 2016. The current action plan was finalised in December 2017 and describes the state of implementation of measures taken after the Fukushima nuclear accident.
It was compiled by the Federal Environment Ministry in cooperation with the supervisory authorities of the Länder and the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS), and with support from the operators of Germany’s nuclear power plants. Immediately after the nuclear accidents in Fukushima, measures were initiated in Germany to review the safety of German nuclear power plants. The Reactor Safety Commission (RSK) subsequently issued recommendations and the GRS prepared an information notice on behalf of the Federal Environment Ministry and sent it to operators and the relevant authorities. These recommendations form the basis for the national action plan. The action plan describes the progress made in implementing the recommendations for increasing robustness in German nuclear power plants. Measures have been taken in all plants, primarily in the area of emergency response, within the framework of nuclear supervision procedures. The national action plan also contains a chapter summarising the deliberations of the Commission on Radiological Protection (SSK) regarding off-site emergency preparedness.
