Seismological risk

According to WENRA, EDF has prepared a plan in case of an earthquake,[3] however other ASN documents from 2002 there may be some anomalies regarding the remote control and which may put into question the correct functioning of certain elements following an earthquake.

2003 heatwave

Following extremely high temperatures in July 2003 average water temperature rose above the limit authorised by the nuclear safety authorities for a period of 4 hours.

Fire risk

According to the 2007 ASN annual report recommendations were made to the operator to improve the security of the control room.[4]
