Les cahiers de l’ASN #02 - Conditions for the continued operation of EDF’s 900MWe reactors

EDF periodically assesses the possible developments of the hazards resulting from climate change and makes sure that these changes are not likely to call into question the protection of the NPPs. In addition, the 4 th periodic safety review will lead EDF to reinforce its NPPs so that they can withstand greater intensities of climatic hazards (tornadoes for example). ASN also requires EDF to study the capacity of the facilities to cope with even higher temperatures than those considered until now. Can the ASN resolution and its requirements regarding the work to be carried out be used to select the 12 reactors to be definitively shut down by 2035? The ASN resolution concerns the technical aspects common to all the 900MWe reactors. It does not address the aspects specific to a reactor or a site. These will be addressed in the periodic safety review of each reactor. ASN requires EDF to report annually on its actions to satisfy ASN requirements and asks that this report be made public. Will the public –the local information committees, people living and working near the NPPs, and beyond– be able to be informed of the work progress? Will the safety review lead to improvements in the protection of the NPPs against the serious disruptions (floods, storms, heat waves, etc.) brought about by climate change?
