After the accident in the Fukushima nuclear power plant in Japan, the European countries decided to undertake a coordinated complementary reassessment of the safety margins in their nuclear power plants, taking into account the lessons learned from the accident so far.
Therefore, the Western European Nuclear Regulators Association (WENRA) and the European Nuclear Safety Regulators Group (ENSREG) defined a detailed programme for carrying out these tests, which was finally approved by the European Commission.
Following this approval, the Spanish Nuclear Safety Council (CSN) issued the relevant Complementary Technical Instructions requiring the owner companies of nuclear power plants to implement the programme. All the licensees sent their reports to the CSN on 31st October 2011 for its assessment by the Council. The regulatory body sent the promised report with the results and conclusions of the assessment to the European Commission on 31st December 2012. The report provided a detailed analysis of the safety conditions in these facilities in the proposed situations and detailed various improvement actions to be carried out as a consequence of this programme. An updated version of this plan was submitted in December 2014 and can be consulted in this article.
