- 212 - This approach resulted in three groups of facilities: A group of 20 priority facilities that would undergo a complementary safety assessment as of 2011; A group of 22 facilities with relatively less important implications, that would be examined in 2012; The remaining facilities, about 35, for which the experience feedback from Fukushima would be taken into account in the periodic safety assessments, which might possibly be brought forward in time. In decisions resolutions dated 5 May 2011, ASN thus finalized the list of facilities that would be examined in 2011 and 2012. The 20 facilities examined in 2011 essentially comprise the fuel cycle facilities, and all those on the La Hague and Tricastin sites. The experimental reactors presenting the greatest challenges have also been considered as priority facilities.
