EDF has submitted its 19 supplementary safety reports for the nuclear sites that are currently operating and those that are under construction to the ASN. This in-depth review of the design of power plants post-Fukushima was launched at the request of the French government, in accordance with the specifications published by the ASN on 5th May 2011. The reports involved reassessing the existing power plants along with those under construction (including EPRs) and checking the safety margins of installations in relation to: the risks of earthquakes and floods; the simultaneous loss of the cooling source and the electricity supply; the consequences of serious accidents and the applicable rules relating to subcontracting.
Firstly, the analyses demonstrate a good level of safety for all of EDF's nuclear facilities. Supplementary measures post-Fukushima have been put forward to the ASN, taking potential situations even further with the aim of continuing to improve the level of safety at the plants.
