11. Examples of AREVA NP activities in Central and Eastern Europe
Completion & Modernization of Mochovce 1 & 2
Main Goals:
- Accident analyses
- Integrity of RPV
- Improvement of core cooling
- Primary-secondary leakages
- Scope and methodology
- I&C supply
- Seismic improvement
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Original systems become outdated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:

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
