    of the hardened safety core These demands are part of a defence in depth approach As such they concern measures to prevent and mitigate the consequences of an accident that exceeds the initial design basis limits for all the facilities on a site This approach involves the deployment of external mobile means which will be completed at the end of 2015 France has also decided to supplement these provisions by implementing substantial fixed means ensuring increased robustness against extreme external hazards ASN s commitment to the pan European work on the management of radiological emergency situations with the aim of harmonising population protection measures on either side of national frontiers It is in this context that the associations HERCA Heads of European radiological Protection Competent Authorities and WENRA Western European Nuclear Regulators Association adopted a joint position 3 at the end of 2014 aiming to improve management and cross border coordination in emergency situations As in the preceding exercise the updated national action plans will be examined by all the European safety regulators ENSREG will organise a seminar in April 2015 at which each safety regulator will present its national action plan and answer questions raised by its counterparts and the public ASN recalls the measures concerning the EDF NPPs decided further to the stress tests At the end of the stress tests ASN underlined in its opinion of 3rd January 2012 that it was going to oblige the licensees to take measures to reinforce protection against natural risks earthquakes and flooding or risks associated with other industrial activities and control the accident situations that could result therefrom loss of electrical power supplies loss of heat sinks severe accidents These requirements oblige EDF more specifically to implement a hardened safety core comprising a limited number of equipment resources that can ensure the safety functions in extreme situations This hardened safety core must be as independent from the existing systems as possible particularly regarding the instrumentation and control and the electrical power supply On 21 January 2014 the ASN Commission adopted 19 resolutions specifying the objectives and the constituents of this hardened safety core EDF proposes setting up this hardened safety core in two phases a first phase comprising the setting up of the fundamental elements of the hardened safety core and more specifically for each reactor a large capacity ultimate back up diesel generator set necessitating the construction of a dedicated building a dedicated ultimate water source and ultimate water makeup and the construction on each site of a local emergency response centre capable of withstanding extreme external hazards These provisions will be implemented gradually starting in 2015 and completed for the most part by 2022 a second phase will supplement the first to improve the level of coverage of the potential accident scenarios considered particularly with respect to the potential consequences of severe accidents These means include the finalising of the ultimate makeup connections to the reactor the installation of an ultimate instrumentation control system and the definitive instrumentation

  • Major challenges for regulating nuclear safety and radiation protection in 2015
    Chairman of the French Nuclear Safety Authority Enlarge the visual The extensive work being done on the French nuclear facilities regarding the monitoring of the nuclear facilities and continued operation for the coming years The continued operation of the nuclear power plants beyond 40 years is not a foregone conclusion P F Chevet was keen to point out This presupposes that the conformity of equipment important for safety with its original design requirements can be guaranteed beyond the fourth safety review that its ageing can be managed and that the safety of the new facilities can be increased ASN pointed out that it will be issuing its initial opinions concerning the nuclear power plants in 2015 and that a generic position statement will in principle be issued in 2018 ASN will then review each reactor individually as of 2020 Twenty six reactors will undergo their fourth ten yearly outages between 2020 and 2025 With regard to the CEA and AREVA facilities experimental reactors fuel cycle facilities etc there are major safety implications with respect to continued operation By 2017 ASN will be receiving the safety review reports on about fifty nuclear facilities For most of them this report will be the first safety reassessment since they were created The lessons from the Fukushima accident have taught us that nuclear facilities must be robust enough to withstand extreme natural hazards P F Chevet pointed out that in 2014 ASN adopted the 19 resolutions setting out additional requirements for implementation of a hardened safety core on the EDF NPP sites and on 9 th January 2015 the 12 resolutions for the AREVA and CEA facilities These resolutions set additional requirements designed to reinforce the prevention and mitigation of the consequences of a severe accident affecting the reactor core or the spent fuel pool They also provide for reinforced measures to enable the licensee to manage an emergency Starting this year ASN will make a detailed analysis of the measures proposed by AREVA CEA and EDF in response to its resolutions more specifically those concerning the hardened safety core The ASN Chairman highlighted the importance of enshrining in legislation the principle of immediate decommissioning of the nuclear facilities shut down and underlined the major challenges in this field whether for the existing French nuclear power plants the former AREVA plants at La Hague and Tricastin or the former CEA facilities The nuclear licensees will be required to devote considerable resources to this so that these facilities can be decommissioned as rapidly as possible and in complete safety Mr Pierre Franck Chevet Chairman of the French Nuclear Safety Authority Enlarge the visual P F Chevet emphasised the changes to the legislative regulatory and technical framework for nuclear safety and radiation protection with the green growth energy transition billand the new Euratom radiation protection and nuclear safety directives The ASN Chairman also indicated that the Member States of the Convention on Nuclear Safety would be meeting in February 2015 in order to improve its effectiveness
