Flamanville EPR reactor: ASN issues its opinion

On 10th October 2017, ASN issued its opinion on the anomaly in the steel used for the Flamanville EPR reactor pressure vessel lower head and closure head. ASN considers that this anomaly is not such as to compromise the commissioning of the reactor pressure vessel, provided that specific checks are carried out during operation of the installation. As the feasibility of these checks cannot at present be confirmed for the closure head, ASN considers that the current closure head cannot be used beyond 2024.
