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 AREVA NP

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Original systems become outdated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 AREVA NP

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

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
