|Dampierre Nuclear Power Plant|
The Dampierre NPP
|Commission date||March 23, 1980|
|Units operational||4 x 937 MW|
Approximately 1,100 people work at the site.
According to a report by the Nuclear Safety Authority in October 2002, certain functions providing backup cooling for the reactor could not be ensured in the event of an earthquake.
On 2 April 2001, during the unit 4 refueling outage, an operator made a mistake in producing the nuclear assembly loading pattern, of which 30% were MOX fuel. The reloading operation was stopped and the core was fully discharged. The incident was reclassified by the ASP at Level 1 of the INES scale.
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.
