  • Complementary safety assessments – Press Release, 14th September 2011
    the accidents at Three Mile Island and Chernobyl in depth feedback regarding the accident Fukushima will be a long process lasting several years 1 In the short term the ASN has conducted complementary assessments of the safety of nuclear French installations in terms of events similar to those that occurred in Fukushima The completion of these assessments is in addition to the safety procedure that is permanently in place as previously described These complementary security assessments are part of a twin framework firstly the organization of stress tests required by the European Council at its meeting on 24th and 25th March 2011 and secondly an audit of the safety of French nuclear installations in the light of events at Fukushima which was referred to the ASN by the Prime Minister under Article 8 of the TSN Act 2 Methodological notes submitted by the operators All operators involved in priority installations to be subject to complementary safety assessment in 2011 EDF CEA AREVA and the Institut Laue Langevin submitted their methodological notes by 1st June 2011 in accordance with decisions taken by the ASN on 5th May 2011 These notes present the methodology used to conduct the complementary safety assessments the organisation set up to meet the prescribed deadlines and the detailed structure proposed for the reports These notes have been subject to a preliminary analysis by the IRSN On 6th July 2011 groups of experts assembled by the ASN examined the methodological notes of the operators and the analysis carried out by the IRSN Expert groups in particular emphasized the ambitious nature of this exercise designed to assess within the expected deadlines the robustness of the installations in extreme situations Based on these findings the ASN found that the methodological approaches submitted by the operators were generally satisfactory provided that these include the additional features they have committed to provide during the course of the analysis and that they comply with the requirements of the ASN These requirements essentially relate to the condition of the installation hazards assessment of safety margins robustness against flooding and taking into account the cumulative effect of earthquakes and flooding incidents in the installation caused by natural hazards and those related to its industrial environment management of serious incidents In particular the ASN asked them to investigate the consequences of the dykes of the Grand Alsace Canal near the site of Fessenheim bursting the dykes of the Donzère Canal near the site of Tricastin bursting and a breach of the Provence Canal near the site of Cadarache The ASN also believes that the quality of complementary safety assessments will depend on the ability of operators to deploy the approach they have proposed in sufficient depth No later than 15th September 2011 operators will submit a first report to the ASN on the results of complementary safety assessments on the installations to be checked in 2011 The ASN and its technical support organisation the IRSN will analyse these reports by the end of 2011 The ASN
