4th periodic safety review of the 900 MWe reactors: EDF issues the first report on the implementation of the generic resolution of ASN

In its resolution 2021-DC-0706, ASN prescribed EDF to report annually on the actions implemented to meet the requirements and their deadlines, and also on the industrial capacity of both EDF and its outside contractors to complete the modifications of the facilities within the set time frames.

EDF has complied with all the requirements of this resolution, which were due to expire in 2021. ASN notes that EDF has not yet identified any alerts regarding compliance with the deadlines for future requirements. The ASN notes, however, that this report identifies several risk factors in the implementation of the planned actions, which will have to be closely monitored by EDF.

900 MWe reactors beyond 40 years

On 23 February 2021, ASN ruled on the conditions for the continued operation of the 900 MWe reactors beyond their fourth periodic safety review. ASN considers that the measures planned by EDF combined with those prescribed by ASN open the prospect of continued operation of these reactors for a further ten years following their fourth periodic safety review.
