Specific phase Starting in 2027, EDF will submit a periodic safety review concluding report* for each 1,300 MWe reactor, based on the studies from the generic phase, and taking the specific features of the reactor into account. This concluding report will describe the works selected for review, and, in particular, those already carried out during the ten-yearly outage. It will be the subject of a public inquiry* and an analysis by ASNR. Finally, ASNR will issue additional requirements for the continued operation of each reactor, following a public consultation on its website. The fourth periodic safety review of the 1,300 MWe reactors follows on from the fourth periodic safety review of the 900 MWe reactors. Therefore, it benefits from feedback from the review of the latter. What does it involve? The fourth periodic safety review of the 1,300 MWe reactors consists of two complementary phases: an initial analysis phase, common to all reactors, known as the «generic» phase (all of the reactors having been designed according to a similar model); and a second, «specific» phase, which takes into account the characteristics specific to each facility – in particular its geographical location (coastal or riverside site, industrial environment, etc.). The associated safety improvements are implemented on the reactors during two maintenance outages. The first of these, the ten-yearly outage*, is the most important.. 2 Rollout phase for safety improvements on each reactor Submission by EDF of the periodic safety review concluding report for the reactor concerned Public inquiry Usually six years after the ten-yearly outage OPERATION UNTIL THE NEXT PERIODIC SAFETY REVIEW Step 2 Step 3 End of rollout of safety improvements for the reactor Step 5 ASNR’s decision on the conditions for continued operation of this reactor Step 4 IFIC PHASE for each of the 20 reactors Conditions for the continued operation of 1,300 MWe reactors beyond 40 years • 5
