Project objective:Adjustment to the international security standard
Scope of service and delivery:75 single projects, basically consisting of:• Security increasing measures• Additional studies and expertise• Measures improving availability• Measures for the improvement of work and maintenance of the facilities
> Replacement of 6kV emergency power switchgear, batteries and rectifiers
> Upgrading of 6kV normal power switchgear
> Installation of new diagnostic systems inside the reactor building (loose parts monitoring (KÜS), moisture-sensitive leakage monitoring (FLÜS), fatigue monitoring (FAMOS))
> Hydrogen monitoring and recombination
> Supply of new fire alarm systems
> Seismic upgrading of existing cabinets
Examples for modernization measures

Completion of Belene NPP Unit 1 & 2 AREVA NP Scope
Heating-Ventilation-Air Conditioning:
Procurement and supply of approximately 3500 safety relevant components Quality Class QA 2 and QA 3, such as:
Fans Independent Air Conditioners Air Handling Units Recirculation Units Air Coolers and Air Filters Water Chillers and Chilled Water Pumps Shut-off Check Valves Containment Isolation and Pressure Relief Dampers Isolation and Control Damper Fire Dampers and Air Tight Dampers
Completion of Belene NPP Unit 1 & 2 AREVA NP Scope
Hydrogen Recombination:
During design bases accidents and especially during beyond design bases accidents large amounts of hydrogen can be released inside the reactor containment.
For high increase in safety, the engineering, procurement, supply and installation of Passive Autocatalytic Hydrogen Recombiners (PAR) are included in our scope
proven high efficiency of catalytic material total prevention of combustion and combustion loads proven high resistance against poisons, cable fumes, oil
fumes, core melt aerosols several years faultless operation experiences in more than 25 plants compact, robust design optimized for back fitting easy in-service inspection with short inspection times due to easy removable catalytic insert and optimized transportable in-service inspection equipment
Excerpt from the joint statement of AREVA NP and Siemens AG answering public rumors:
„Siemens AG and AREVA NP have stated clearlyand without doubt that their successful cooperation,especially in the field of Instrumentation & Control, will continue after the withdrawal of Siemens AG as shareholder of AREVA NP based on existing and future agreements.
Please be assured of our full commitment to bring the Belene plants successfully into operation.“
