  • Complementary safety assessments – Press Release, 14th September 2011
    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 has stated that the complementary safety assessments are the first step in the feedback process after the accident in Fukushima This process will develop over several years 3 Targeted inspections In addition to complementary safety assessments in 2011 the ASN initiated a campaign of targeted inspections on issues related to the accident in Fukushima These inspections conducted on all nuclear installations considered

  • Supervision of the EPR reactor: Information notice No. 11
    On 1 July 2011 considering that the actions adopted by EDF would result in the proper conduct of work on the prestressing sheaths ASN authorised EDF to pursue concreting activities on the inner containment wall An unscheduled inspection was performed on 12 July 2011 on this issue The conclusion of the inspection is that implementation of EDF s action plan is satisfactory overall see follow up letter INSSN CAE 2011 0662 Reminder regarding complex concreting requirements General view of Reactor Building cavity under construction On 7 July EDF notified ASN that rock pockets 2 had been detected in certain concrete walls of the Reactor Building cavity This information follows several requests for additional information and inspections by ASN regarding the method chosen for concreting the structures In addition to handling such occasional deviations for which repairs were already planned ASN sought to verify if they demonstrated possible organisational lapses strict requirements for the worksite require correct performance of operations to avoid the need for future corrections On 12 July 2011 ASN s inspectors examined measures taken by EDF and its primary civil engineering subcontractor responsible for concreting the Reactor Building cavity Inspectors also examined the defects on site before repair The technical exchange revealed that defects result from the difficulty of pouring concrete in complex shapes with dense reinforcement using the adopted method Among other things inspectors noted that cleaning prior to pouring was incorrectly performed and inspected On 10 August 2011 ASN thus requested EDF to provide a report on the quality of the concrete walls affected by the defects after repairs are completed identify if such complex concreting could have led to defects for which visual inspections are not possible define appropriate preventive measures particularly concerning inspection and skill of workers so that future concreting operations are fully mastered present operating experience feedback or useful lessons contributing to mastering the activity prior to the next complex concreting operations EDF has already given its response which addresses worker training and increasing monitoring of activities by the firms concerned Rock pockets before repair on a wall of the Reactor Building cavity Ongoing examination of instrumentation and control I C system The Flamanville 3 EPR I C system comprises two platforms the Téléperm XS platform specifically developed for the nuclear industry and designed to protect the reactor during incidents and accidents the SPPA T2000 platform a conventional industrial component used for normal reactor operation with certain functions designed to protect the reactor during incidents and accidents In response to ASN s request dated 9 July 2010 EDF presented design measures that differ from those initially planned The measures include grouping certain safety functions that were not part of the Téléperm XS platform in a hard kernel system The measures enable handling a situation which includes complete loss of the SPPA T2000 platform combined with certain accident situations At the same time EDF in coordination with the designers and manufacturers concerned completed a significant effort to demonstrate that certain safety functions could
