2011 was a watershed year for EU nuclear policy essentially due the accident at the Fukushima Nuclear Power Plant in Japan in March. This event changed the EU institutions' nuclear agenda and put safety at the top. Thus, in addition to expected developments like the adoption by the European Council of the nuclear waste Directive and of the Energy Roadmap 2020 and the publication by the European Commission of the Low-carbon 2050 Roadmap and the Energy 2050 Roadmap, a new process called the "stress tests" was launched in order to re-evaluate the safety of nuclear power plants in the EU in the light of the Fukushima accident. Please find here a brief summary of all the events that influenced the EU energy policy in 2011.
