The Paris division regulates radiation protection and the transport of radioactive substances in the 8 départements of the Île-de-France region. The Orléans division regulates nuclear safety in the BNIs of this region. Île‑de‑France Region ASN carried out 272 inspections in the Île-de-France region in 2021, of which 84 were in the field of nuclear safety, 135 in small-scale nuclear activities, 24 in the transport of radioactive substances and 29 concerning approved organisations or laboratories. In the small-scale nuclear activities sector, 2 significant eventswere rated level 2 on the ASN‑SFRO scale, and 8were rated level 1 on the INES scale. CEA SACLAY SITE Since 2017, the CEA Paris‑Saclay centre accommodates activities previously conducted on several geographically distinct sites close to Paris, and the sites of Saclay and Fontenay-aux‑Roses in particular. The CEA Paris-Saclay centre, of which the main site covers an area of 125 hectares, is situated about 20 km south-west of Paris, in the Essonne département. About 6,000 people work there. Since 2005, this centre has been primarily devoted to physical sciences, fundamental research and applied research. The applications concern physics, metallurgy, electronics, biology, climatology, simulation, chemistry and the environment. The main aim of applied nuclear research is to optimise the operation and enhance the safety of the French NPPs. Eight BNIs are located on this site. Nearby are also located an off ice of the French National Institute for Nuclear Science and Technology (INSTN) –a training institute– and two industrial firms: Technicatome, which designs nuclear reactors for naval propulsion, and CIS bio international, which produces radiopharmaceuticals for nuclear medicine. THE INDUSTRIAL AND RESEARCH FACILITIES Osiris and Isis reactors The Osiris pool-type reactor has an authorised power of 70 Megawatts thermal (MWth). It was primarily intended for technological irradiation of structural materials and fuels for various power reactor technologies. Another of its functions was to produce radionuclides for medical purposes. Its critical mock-up, the Isis reactor with a power of 700 kilowatts thermal (kWth), was essentially used for training purposes. These two reactors were authorised by a Decree of 8 June 1965 and constitute BNI 40.
