France’s nuclear regulator, the Autorité de Sûreté Nucléaire (ASN), has defined the preconditions for the resumption of forging operations at Areva’s Le Creusot forge. The facility has been out of operation since December 2015 following the discovery of quality assurance issues. 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 French nuclear safety regulator said an ongoing quality audit at Areva’s Le Creusot forge – which Areva bought in 2006 – had identified “irregularities” in paperwork on some 400 plant components produced there since 1965. The issues “comprise inconsistencies, modifications or omissions in the production files, concerning manufacturing parameters and test results”, it said.
