Incidents

On 2 April 2001, during a refueling outage of unit 4, an operator made a mistake in following the correct loading pattern for the different fuel rod assemblies. The reloading operation was stopped and the core completely unloaded. The incident was initially classified at Level 1 of the INES scale, but reclassified as Level 2 by France's nuclear safety authority in 2007.
On the night of 9 to 10 April 2007, reactor No. 3 went on emergency standby and remained so throughout the night; it was supplied with emergency power by an emergency generator. EDF triggered an emergency plan to 22h10. Throughout the night, teams acted in emergency mode, the reactor No. 3 having been deprived of its external power. The emergency generator worked well. The ASN has established a national crisis with the support of the IRSN. EDF and DSC lifted the crisis the following morning at 8:15. Following this incident, the No. 3 reactor remained shut down for several weeks to correct the problem.
