ASN Report 2022

Île‑de‑France REGION 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. ASN carried out 313 inspections in the Île-de-France region in 2022, of which 107 were in the field of nuclear safety, 149 in small-scale nuclear activities, 27 in the transport of radioactive substances and 30 concerned approved organisations or laboratories. Ten significant events were rated 1 on the INES scale in the small-scale nuclear activities, 3 in the BNIs and 6 in the transport of radioactive substances. 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. Seven BNIs are located on this site. Nearby are also located an office 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. THE INSTALLATIONS AND ACTIVITIES TO REGULATE COMPRISE: Basic Nuclear Installations regulated by the Orléans division: •the CEA Saclay site of the CEA Paris‑Saclay centre, •the Artificial Radionuclide Production Plant (UPRA) operated by CIS bio international in Saclay, •the CEA Fontenay‑aux‑Roses site of the CEA Paris‑Saclay centre; small-scale nuclear activities in the medical sector regulated by the Paris division: • 26 external-beam radiotherapy departments, • 12 brachytherapy departments, • 41 in-vivo nuclear medicine departments and 13 in-vitro nuclear medicine departments (medical biology), • 149 centres performing fluoroscopy-guided interventional procedures, • more than 200 centres possessing at least 1 computed tomography scanner, • about 850 medical radiology practices, • about 8,000 dental radiology devices; small-scale nuclear activities in the industrial, veterinary and research sectors under the oversight of the Paris division: • some 650 users of veterinary radiology devices, • 8 industrial radiography companies using gamma radiography devices, • some 100 licenses concerning research activities involving unsealed radioactive sources; activities associated with the transport of radioactive substances; ASN-approved laboratories and organisations: • 4 organisations approved for radiation protection controls.
