17 The Flamanville 3 EPR project Industrial stakes Maintain EDF s leadership and competency in nuclear development Prepare the renewal of EDF s fleet Technical performance Net base power capacity 1650 MW Service life of 60 years Increased reliability in operation, availability factor 91%, Radioprotection : annual doses divided by 2 : 0.35 HSv/year Environmental improvement Reduction of radioactive waste by 30 %, Reduction of liquid radioactive waste / MWh by 30 % (apart tritium and C14) Reduction of gaseous release / MWh by 30 % to 40 % (apart C14) Economy Investment 4bn 2008 Generation cost of the FOAK /MWh 17

18 Flamanville 3 EPR project preliminary steps 2004 Selection of Flamanville site and application for the Public Debate according to Environmental law 2005 to April 2006 May 4, 2006 Mid 2006 to end 2007 December 2007 Public Debate (more than 20 meetings all around France) Decision by EDF s Board of Directors to launch the Flamanville 3 project Administrative procedures DAC (application for the realization authorization) April 2007 Awarding of major contracts Site preparation works «First concrete» date of the reactor building basement 18

19 Project management : EDF as Architect Engineer As an Architect Engineer, EDF s responsibilities involve: Managing the project (quality, schedule, costs, risks, interfaces ) Fronting the French Nuclear Safety Authority (Responsible of the Nuclear License) Deciding how contracts are to be shared out, placing and then managing them Defining technical reference of the plant (general specifications for equipment, for buildings, for the general operation ) Optimizing the ownership cost by including feedback from French nuclear fleet in the design and operation Controlling suppliers detailed studies and equipment manufacturing quality Controlling on-site construction and commissioning tests 19

20 Role of Flamanville 3 players : project architecture on 3 levels Architect Engineer Level 1 EDF Detailed Studies Level 2 Boiler BNI* BOP & Site auxiliary buildings AREVA SOFINEL EDF ALSTOM 55% EDF, 45% AREVA Engineering contracts Turbine and Generator Building EDF Suppliers Level 3 Supply and construction contracts Bouygues, * BNI : Nuclear Island excluding boiler Study contracts Supply contracts 20

21 Allocation of main contracts Around 150 contracts - Systematic competition excluding Nuclear Steam Supply System - NSSS - (Areva NP) To date, commitments represent 99% of the total EPR contract amount The 6 largest work contracts account for around 70% of the project budget Prices are indexed (reference index) These contracts include sections at lump sum prices and sections at unit prices Breakdown of total contract amount Works at sea Metal frame Ventilation Simulators Diesels Rolling bridges Paintings Electrical installation Other NSSS 21 Piping Order Control Conventional island Civil work

22 Main stages in the Flamanville 3 project Decree for Authorisation to build the Flamanville 3 nuclear plant 1 st concrete for the reactor poured onto the Flamanville site (on schedule) Civil Engineering Electro mechanic work (piping, cabling) Commissioning of the plant Connection to the grid April 2007 Dec Mid 2011 Mid

23 Priority to safety and quality EDF s engagements about quality The worksite teams are mobilized on safety and quality Increase of the number of Safety Authority controls on design, fabrication and construction activities: 2 inspections on site per month + 2 inspections of design department or fabrication plant per quarter => Inspection results are communicated on SA website. FA3 design deliverables to ASN spread until oct Non conformances, quarterly progress report to ASN 23

24 On-site work progress Completion of preparatory work 1 st concrete for the reactor building poured in early December 2007 as scheduled Completion of the whole raft foundation of the reactor building Erection of the first section of liner and pouring of the containment of the gusset Turbine hall: pouring of the turbine generator pedestal and assemblage of the roof structure Beginning of the electromechanical erection 24

25 Feedback from the first months of construction Points worth watching: Technical hazards: Volume of steel rebars in civil engineering work Welding of the liner (metal skin) Delay in drilling the well on land for the work of discharging water in the sea Quality of surveillance Regulatory changes: «Nuclear Equipment Under Pressure» regulation, «Malicious Damage» regulation Strengths: Conventional island Assembly underway on schedule Manufacture of large components underway with no significant delay Simulator Delivery of an initial version of the simulator in June 2008 The availability of a simulator less than one year after the 1 st concrete is unprecedented for a new design reactor Continuous improvement in the project monitoring process Strict supervision on the nuclear expertise of companies Better anticipation Improving quality of the surveillance of the site activities 25

26 Confirmation of the target of reactor start-up in 2012 Control of project hazards encountered so far Confirmation of delivery dates for major equipment by the main suppliers Implementation of an appropriate organizational structure aimed at anticipating the most probable difficulties 26

34 3 EDF International Nuclear development

35 EDF s strategy EDF intends to invest and play an industrial role in the nuclear energy renaissance Investment, construction and operation of EPR- type nuclear power plants around the world : operational know-how engineering expertise through its oversight of major projects longstanding international partnerships Duplication of the Flamanville 3 reference Use of the series effect to develop an EPR fleet 35

36 EDF s Fundamental Criteria to commit itself on a New Nuclear Build Abroad 1. Countries choosing to develop nuclear energy in the short-term 2. Countries where EDF is welcome 3. Countries with favorable conditions for investors in nuclear energy Comprehensive legal framework Effective regulatory system Long term management policy of nuclear materials and radioactive waste Public opinion in favor 4. Projects based on proven reactor design 5. Local partners with good track record in building and operating electricity generation 6. Financial criteria meeting the Group s financial targets and risk policy 36

37 Four selected countries for EDF investment in the nuclear renaissance United Kingdom : a joint application for GDA with AREVA Plans for 4 EPR (1st commissioning 2017) United States : a joint venture with Constellation Energy for the joint development of EPR-type nuclear power plants UNE COLA application to NRC March 2007 for Calvert Cliff China : Over 20 years of strong cooperation in all areas of nuclear power generation a joint venture with CGNPC for 2 EPR in Taishan Italy : an agreement with ENEL (consortium 50/50) for development JV of a fleet of at least 4 EPR 37
