EDF’s 900-MW Fessenheim-2 nuclear reactor may have to remain shut, until anomalies are corrected

EDF reactor may remain shut after regulator suspends certificate London (Platts)–19 Jul 2016 EDF’s 900-MW Fessenheim-2 nuclear reactor may have to remain shut beyond the end of scheduled maintenance after French nuclear safety authority ASN said Tuesday it had suspended a certificate for one of the reactor’s steam generators, in which several anomalies were discovered in June.

“ASN has suspended the test certificate it issued to Areva NP in 2012 for a steam generator currently installed on reactor 2 of the Fessenheim nuclear power plant,” ASN said.”This suspension is consecutive to the detection of an irregularity in the manufacturing, by Areva’s Creusot Forge factory, on one of the parts of this steam generator,” ASN said in the statement.

ASN issues test certificates for the most important nuclear equipment, and these certificates are required for the commissioning of the equipment. The suspension of the test certificate, ASN said, would result in the Fessenheim-2 reactor remaining shut until Areva NP — the reactor unit of Areva and owner of the Creusot Forge — demonstrates the steam generators can meet the regulatory standards.

Le Creusot Forge manufactures forgings and castings for the large components of nuclear reactors.

ASN said it had asked Areva NP to send the agency details on how it intends to rectify the steam generator’s problems……..http://www.platts.com/latest-news/electric-power/london/edf-reactor-may-remain-shut-after-regulator-suspends-21023392
