The CEA in brief...


To fulfil its duties defined by the government, the CEA relies on four operational divisions active on 10 different sites in France, themselves supported by a number of functional departments. The functional departments provide all the CEA’s support services: funding & programmes; human resources & labour relations; communications, legal affairs & disputes; purchasing & partnerships; international relations; auditing, risks & internal control. The CEA also manages the French National Institute for Nuclear Science and Technology (INSTN), a higher education and vocational training organisation working in fields of low-carbon energy sources and health technologies.

4 operational divisions

Military Applications Division (DAM)

The role of the CEA Military Applications Division is to support France’s defence and security services. It designs, develops and maintains the safety and reliability of its nuclear warheads for deterrence. It also designs and builds nuclear steam supply systems to power the French Navy’s vessels. The DAM assists the French nuclear safety authorities in its fight against nuclear proliferation and terrorism. Lastly, its expertise in defence is put to good use to assess and better manage the effects and weaknesses of conventional weapons.

Energy Division (DES)

The CEA Energy Division provides the French public authorities and industry with the technical expertise and innovation needed to develop low-carbon power generation systems. Based on an integrated approach to energy systems, the DES explores all available means of low-carbon power production (nuclear, new energy technologies), along with issues like grid interfaces (storage, control, energy conversion) and resource management within a closed cycle, while taking into account technical, economic, societal and political aspects.
