had listed them a day before as a level 4 event. Later on they said they believed the situation had surpassed that of a level 5 event and moved to a level 6. Their opinion was shared by the Finnish nuclear authorities.
During 2015 and 2016 major nuclear safety issues arose, following a discovery at the
Flamanville Nuclear Power Plant
The Flamanville Nuclear Power Plant is located at Flamanville, Manche, France on the Cotentin Peninsula. The power plant houses three pressurized water reactors (PWRs). Unit 1 and 2, rated 1.3 GWe each, and based on Westinghouse design, were o ...

leading to 20 of France's 58 reactors being offline in October 2016.
These steel quality concerns may prevent the regulator giving the life extensions from 40 to 50 years, that had been assumed by energy planners, for many reactors.
Le Creusot Forge had maintained concealed files which had now been disclosed to ASN following new management by

. ASN characterised the current situation in January 2017 as worrying.
In April 2017 ASN published the requirements for forging to resume at Le Creusot Forge, which has been out of operation since December 2015.
In 2018 ASN introduced stricter monitoring of component production in response to the problems found at Creusot Forge.
In 2025, it merged with
IRSN to become
ASNR.
