The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas:

• Defence and security,

• Low carbon energies (nuclear and renewable energies),

• Technological research for industry,

• Fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, the CEA actively participates in collaborative projects with a large number of academic and industrial partners. The CEA is established in nine centers spread throughout France. It works in partnership with many other research bodies, local authorities and universities. Within this context, the CEA is a stakeholder in a series of national alliances set up to coordinate French research. The CEA is the only French research organization to be listed in the Clarivate 2020 ranking and is the leading French research organization filing patents in Europe, according to the European Patent Office (EPO) 2021 ranking.
