26 EPR reactor certified by EUR 99.9% of EPR features comply with EUR requirements* * Statistics established over 4678 requirements The certificate attesting to the EPR reactor s compliance with European utility requirements was officially awarded to AREVA on July The EPR reactor has outstripped the EUR specifications in the following areas: Protection against the airplane crash (the risk of the large commercial aircraft is covered), Spent fuel storage capacity Life expectancy of 60 years against 40 required by the EUR 25

27 AREVA worldwide engagement in EPR licensing Hinkley Point C Olkiluoto 3 UK NSL + GDA Nov. + Dec Construction License February 2005 Flamanville 3 USA (COLA) Taishan 1&2 Design Certification of US EPR : 2014/2015 The EPR TM reactor is: Construction License April 2007 The only Gen3 model under construction in the EU The only reactor designed within the EU The only reactor licensed by 3 independent European regulators Construction License October

28 The value of Experience Standardization of early engineering activities System activities: Input data for other disciplines ready earlier and better defined P&ID : Important input for layout in order to validate Civil Works (CW) interfaces DSE stage 2 : important input for I&C OL3 Taishan NSSS engineering standardized and streamlined -60% % P&ID First issue (months) -33% System Description Stage 2 - First issue (months) % Piping isometrics Nb of revisions OL3 Taishan Number of engineering hours for NSSS completion (for Taishan: estimate) 27

30 Key Messages The EPR TM Reactor is an evolution of mature French and German reactors, incorporating proven technologies as well as innovations validated through R&D programmes The Safety features of the EPR TM Reactor integrate the lessons learned from the past. They have been deemed necessary and sufficient by the safety authorities of advanced nuclear countries as fulfilling the most stringent GEN III safety objectives, until March 2011 The lessons learned from the Fukushima event are not yet all drawn A preliminary evaluations show that the EPR TM reactor would have withstood the earthquake and the subsequent tsunami The soundness of the EPR TM reactor design was confirmed by the complementary safety evaluations (stress tests) performed by the European Regulators ; however light improvements may be incorporated to satisfy new requirements 29
