As the world's leading nuclear operator, the EDF Group is the leader of a strategic industrial sector of excellence and has unique expertise in this field. One of the priority roles of R&D is to support and perpetuate this major asset for the Group.

R&D is working to protect EDF's assets by making its actions part of the process of improving the safety of installations, seeking to improve performance and extend the operating life of reactors.

To do this, R&D researchers rely on unique testing resources and laboratories. Discover some of these emblematic laboratories!

We offer you here a first overview of our laboratories and testing facilities, not exhaustive. Please visit our page regularly, as more content will be added in the coming weeks and months.
