The French nuclear safety regulator has introduced stricter measures for monitoring the production of components, as a response to irregularities found in paperwork at the Creusot Forge. Licensees and manufacturers have until 1 September to implement them. The Autorité de Sûreté Nucléaire (ASN) announced in April 2015 the discovery of an anomaly in the composition of the steel in certain zones of the vessel closure head and the vessel bottom head of the Flamanville EPR reactor. The detection of this anomaly led ASN to ask Areva NP and EDF to “learn all possible lessons from this event”. In May 2016, the regulator said an ongoing quality audit at Le Creusot forge – which Areva bought in 2006 – had identified “irregularities” in the paperwork of some 400 plant components produced there since 1965. “Irregularities of the same type had also been brought to light in other countries,” ASN noted.
