ASN allows restart of the reactors of the Tricastin nuclear power plant (NPP)

With the support of IRSN, ASN examined the data provided by EDF to demonstrate the seismic resistance of the Donzère-Mondragon canal embankment which protects the Tricastin NPP. ASN considers that, following the investigations and repairs carried out by EDF, the condition of the embankment allows the restart of the EDF reactors and gave its consent for the restart of reactors 2, 3 and 4.
