  1. Introduction of AREVA groupand Project Experience with Modernization of VVER Reactors

  2. AREVA: Steps towards a global leadership in the energy industry Within 5 years, AREVA has established itself in the international energy market as a leader in nuclear technology April 2006 New name, clear structure • To underline this develop- ment, the Board of Directors decided to structure the AREVA group into AREVA NP, AREVA NC and AREVA T&D

  3. AREVA engineering and supplies • Front End Division(AREVA NC) • Reactors and Services Division (AREVA NP) • Back End Division(AREVA NC) • Transmission and Distribution Division(AREVA T&D)

  4. Legal Structure of the AREVA group 2005: € 10,1 billion sales 58.760 employees 34% 66% 100% 100% AREVA NP AREVA NC AREVA T&D Equity interests ENERGY AREVA NP is an AREVA and Siemens company.

  5.

  6. AREVA around the globe 40 countriesProduction & Manufacturing 100 countriesMarketing & Sales € 6,754 M: 67%of all sales come from outside France EUROPE & CIS 63%of sales - Nuclear: 77% - T&D: 23% 43,279employees ASIA-PACIFIC 12%of sales- Nuclear: 45% - T&D: 55% 5,824employees NORTH & SOUTHAMERICA 18%of sales - Nuclear: 74% - T&D: 26% 7,912employees AFRICA & MIDDLE EAST 7%of sales- Nuclear: 12% - T&D: 88% 1,745employees Production & manufacturing

  7. Examples of AREVA NP activities in Central and Eastern Europe • Upgrade safety level to meet current requirements • Improve operational features • Enhance competitiveness • Remove aging effects • Extent plant license and lifetime • Faciltate EU accession Areva NP modernizes VVER NPPs in order to:

  8. Examples of AREVA NP activities in Central and Eastern Europe AREVA NP references in VVER NPPs: • Modernization of Kozloduy 5 & 6 * • Rest lifetime assessment and modernization of Kozloduy 3 & 4 * • Participation in new NPP Tianwan 1 & 2 * • Reconstruction of Bohunice V1 • Completion and modernization of Mochovce 1 & 2 * • I&C replacement in Paks, Dukovany and Loviisa • Various co-operation projects in Russian NPP (Kola, Kalinin, Balakovo, Novovoronezh) • Various co-operation projects in Ukrainian NPP (South Ukraine, Zaporozhye, Rovno, Khmelnitsky, Chernobyl) * in co-operation with Atomstroyexport

  9. Examples of AREVA NP activities in Central and Eastern Europe Kozloduy 5 & 6 (VVER1000) – Modernization Project Long term core cooling improvement Emergency power supply and electrical systems improvement Containment integrity Instrumentation and control Radiation monitoring system Diagnostic and computerised information systems Replacement and modernisation of information systems Internal and external hazards Safety analyses and operation documents Mechanical analyses

  10. Examples of AREVA NP activities in Central and Eastern Europe • Reduction of radiation exposure • Confinement leak-tightness and localization system improvement • Improvement of ECCS and confinement spray system • Pressure suppression system • Bohunice V1 (VVER 440/230) - Targets of Modernization • Reduction of core damage frequency • Increased reliability of reactor trip system, ECCS safety features and confinement spray system • Reduced probability of double ended guillotine break of 500 mm RCS lines • Improvement ECCS against extended LOCA spectrum, based on new DBA • New digital safety I&C • Seismic reinforcement up to scale 8 • Update ofsafety documentation / emergency operating procedures

  11. Examples of AREVA NP activities in Central and Eastern Europe Main Goals: - Integrity of RPV - Improvement of core cooling - Primary-secondary leakages - Seismic improvement - Scope and methodology - Accident analyses -I&C supply Completion & Modernization of Mochovce 1 & 2 Final Statement by Riskaudit (2000): “Mochovce Nuclear Power Plant is the first soviet designed nuclear power plant completed in an East European country that achieved a safety level comparable with western standards”.

  12. Examples of AREVA NP activities in Central and Eastern Europe I&C modernization: What are the specific arguments? • To keep up with rapid development of technologies • Original systems become outdated • Increasing cost to guarantee for spare parts and adequate service • Modern digital technology has key advantages • It reduces time and cost for diagnostics and tests • It offers more flexibility for plants operation • It contributes to cost optimization • Long term supply for modern systems assured

  13. Examples of AREVA NP activities in Central and Eastern Europe • Bohunice V 1 - Modernisation of I&C • Reactor shut down system • Control of emergency and residual heat removal (ESFAS) • In-core measurement • Neutron ex-core measurement • Emergency instrumentation • New design for main and emergency control room • Radiation control • Diagnostic systems Unit 2: completed 1999 Unit 1: completed 2000

  14. Examples of AREVA NP activities in Central and Eastern Europe I&C Replacement in NPP Paks (VVER 440/213) • Replacement of I&C by Teleperm XS: • Reactor shut down system, ESFAS • Neutron flux measurement • Testing system for I&C-Tests HW and SW • Environment for further improvement • Project Status: • Unit 1: since 1999 in operation with TXS • Unit 2: since 2000 • Unit 3: since 2001 • Unit 4: implementation in April/May 2002

  15. Examples of AREVA NP activities in Central and Eastern Europe • Conclusions: • After 2 decades of operation, modernization is required to maintain competitiveness, to adopt to newest standards and to assure further safe operation • Operational and safety improvement is the basis to obtain public acceptance and to reach common ecological and economical targets • VVER in Central and Eastern Europe which have passed through comprehensive modernization programs achieved above targets • The key for success is the international co-operation of strong and experienced partners

  16. Examples of AREVA NP activities in Central and Eastern Europe • New Challenges: • After successful completion of several mutual projects AREVA aims to cooperate as a partner of Atomstroyexport in the Belene NPP • AREVA offered supplies are mainly related to safety measures, I&C, electrical systems, heating, ventilation and air conditioning • Currently, AREVA cooperates with Atomstroyexport in the new VVER of Tianwan 1+2 with a comparable scope of supplies • AREVA´s participation in Belene will facilitate public and political (EU) acceptance and support to reach Bulgaria´s ecological and economical targets
