CEA Paris-Saclay

Since February 2017, various sites were grouped together to the CEA Paris-Saclay center, including • Caen site (GANIL and ) == History ==

On 10 October 1945, Charles de Gaulle launched the CEA. In 1946, the Fontenay-aux-Roses site was realized, followed by the Saclay site 6 years later in 1952. The Saclay site, located 20 km south of Paris on the Saclay plateau, is much bigger and was chosen in part to be close to Université Paris-Sud (which today is part of Paris-Saclay University). The Saclay site was designed by the architect Auguste Perret. == Research ==

The complex employs more than 7,500 scientists. • Low-carbon energies • Climate and environment • Matter and universe • Health and life sciences • Technology for industry Reactors The Saclay site has been home to multiple nuclear research reactors, including the , and reactors. The Osiris and Isis reactors (operated between 1965 and 2019) inspired the design of Iraq's facility. Multiple bacterial species were discovered to thrive in those reactor cores during operation, and may have fed off hydrogen from radiolysis. == Notable subsidiaries ==
