To keep up with rapid development of technologies Original systems become outdated Increasing cost to guarantee for spare parts and adequate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
I&C modernization: What are the specific arguments?

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
Conclusions:

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
