Generic phase of the fourth periodic safety reviews of the 1300 MWe reactors

On 11 December 2019, ASN issued a position statement on the orientations of the generic phase of the fourth periodic safety review of EDF’s 1300 MWe nuclear reactors. ASN considers that the general objectives set by EDF for this review are acceptable in principle. However, it asks EDF to modify or supplement these general objectives for this safety review, to consider certain baseline requirements for reassessment of the safety of its facilities and to add study topics to its review programme. The requests made by ASN are to a large extent based on those made in 2016 for the fourth periodic safety review of the 900 MWe reactors.
