EDF should repair faulty weldings at the nuclear plant it is building in northern France, according to the technical arm of French nuclear regulator ASN. The recommendation by IRSN, which could be confirmed by ASN in a ruling expected as early as June, could cost the utility hundreds of millions of euros and lead to further delays at the reactor in Flamanville. “Given the importance of the identified defects, the IRSN has concluded that EDF, rather than trying to justify that the weldings are fit for service in their current state, should proceed to repair the weldings,” IRSN said in a statement. In a separate statement, ASN said a group of independent nuclear experts had also recommended that EDF either repair the weldings or make improvements to the reactor’s design so that it could withstand breakage of the weldings.

EDF: Experts recommend repairing EPR welds. A group of experts mandated by the Nuclear Safety Authority (ASN) unanimously recommends that EDF repair the most problematic faulty welds in the Flamanville EPR reactor (Manche). learned source Thursday familiar with the record. This recommendation is not binding on ASN but may lead to a further delay in the commissioning of the reactor if, if the authority followed the advice of the expert group, it could force EDF to take over welds that the group is considering for the moment to maintain in the state.
