A single player in France and internationally

Design, manufacturing, in service monitoring and life span

You design, build or maintain components of nuclear power plants or nuclear fuel reprocessing plants.

There are many requirements related to the diversity of the materials used, installation operating conditions, regulations, codes and specifications.

We propose a comprehensive service dedicated to the nuclear industry, from design to fitness-for-service studies and maintenance of your facilities, thus avoiding the involvement ouf numerous parties.

We assist you in carrying out dimensional designs for all equipment in accordance with standards in force.

We work on your manufacturing projects through technical welding and metallurgy assistance missions and engineering missions.

We monitor your manufacturing operations. We assist your in determining the inspection specifications. We qualify your non-destructive test methods and test the new equipment.

We are a member of the Association for the safety of pressure equipment (ASAP) and we are authorised to decide upon conformity of your new pressure vessels. We can also work within a contractual framework (second and third party inspection).

We supervise your non-destructive testing operations during maintenance steps.

Finally, we can help you extend the life of your equipment through our expertise and advice. We can study the harmfulness of defects and possibly validate them. We advise you about measures to be taken to put your installation back into service.
