Memorandum in reply against: - Opinion nr 217-AV-0298 of the Nuclear Safety Authority of the 10 October 2017 related to the anomaly of the composition de the vessel bottom and cover of the EPR reactor of the Flamanville nuclear plant (INB nr 167); - The decision nr 2018-DC-0643 of the Nuclear Safety Authority of the 9 October 2018 authorising the entry into service and use of the EPR reactor vessel of the Flamanville nuclear plant (INB nr 167)

Two memorandums in reply are addressed by a group of associations to the French State Council about an opinion and a decision issued by the ASN regarding the anomaly noticed for the composition of the steel used for the fabrication of the Flamanville EPR reactor vessel and cover. The first memorandum is a reply to an answer given by the ASN to a first memorandum which deposited a recourse for abuse of power against an opinion issued by the ASN. This memorandum is based on a series of statements, decisions and publications by different involved actors. It notably highlights that the opinion issued by the ASN is in some respects illegal. The second memorandum is an answer to a memorandum of defence produced by the ASN. It notably addresses the admissibility of the application and the illegal aspects of the opinion
