OR:

The French Alternative Energies and Atomic Energy Commission, or CEA ( French: Commissariat à l'énergie atomique et aux énergies alternatives), is a French public government-funded research organisation in the areas of energy, defense and security, information technologies and health technologies. The CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. CEA is headed by a board headed by the general administrator (currently François Jacq since 20 April 2018), advised by the high-commissioner for atomic energy (currently ). Its yearly budget amounts to €5.8 billion and its permanent staff is slightly over 21,000 persons.

CEA in Academics


University of Paris-Saclay

CEA has played an active role in research, development and innovation in the four main areas of low-carbon energies (nuclear and renewable), technologies for information and health technologies, very large research infrastructures (TGIR), and defense and global security. Moreover, two of the ten CEA centers across France have joined with the
University of Paris-Saclay Paris-Saclay University (, ) is a combined Research institute, technological research institute and Public university, public research university in Orsay, France. Paris-Saclay was established in 2019 after the merger of four technical ''grandes ...
to develop high quality research and training. The centers which form a part of the University of Paris-Saclay include: * CEA Saclay Center, which conducts research mainly in areas related to climate and environment, materials science, nuclear energy, life sciences and technological research * CEA Fontenay-aux-Roses Center, which conducts research and innovation in areas related to imaging and biomedical technologies (Since 2017, these two centers merged into CEA Paris-Saclay center, and are now referred to as sites in that center.) The CEA researchers involved in the University of Paris-Saclay represent over 20% of the university's research potential, particularly in the field of physics and engineering. CEA maintains a strong presence in training to master and engineer level by administering INSTN, wherein various courses are taught by its researchers. CEA has around 400 researchers who hold an accreditation to supervise research, making it a significant contributor to the research and doctoral programs of the University Paris-Saclay.


INSTN

The INSTN, '' Institut national des sciences et techniques nucléaires'' (National Institute for Nuclear Science and Technology) is a public higher education institution administered by the CEA (French Atomic Energy and Alternative Energies Commission) under the joint authority of the Ministry of National Education, Higher Education and Research, the Ministry of the Economy, Industry and the Digital Sector and the Ministry of the Environment, Energy and Marine Affairs.
