Cadarache site CEA CADARACHE CENTRE Created in 1959, the CEA Cadarache centre is situated in the municipality of Saint-Paul-lez-Durance in the Bouches‑du‑Rhône département and covers a surface area of 1,600 hectares. This site focuses its activity primarily on nuclear energy and, as concerns its civil installations in operation, on research and development to support and optimise the existing reactors and the design of newgeneration systems. A large part of the centre’s facilities are moreover involved in conducting the strategy for decommissioning and management of radioactive materials and waste of the Alternative Energies and Atomic Energy Commission (CEA). The following BNIs are located on the site: ∙ the Pégase‑Cascad installation (BNI 22); ∙ the Cabri research reactor (BNI 24); ∙ the Rapsodie research reactor (BNI 25); ∙ the Plutonium technology facility (ATPu – BNI 32); ∙ the Solid Waste Treatment Station (STD – BNI 37-A); ∙ the Active Effluent Treatment Station (STE – BNI 37-B); ∙ the Masurca research reactor (BNI 39); ∙ the Éole / Minerve research reactor (BNI 42-U); ∙ the Enriched Uranium Processing Facilities (ATUe – BNI 52); ∙ the Central Fissile Material Warehouse (MCMF – BNI 53); ∙ the Chemical Purification Laboratory (LPC – BNI 54); ∙ the High-Activity Laboratory LECA‑STAR (BNI 55); ∙ the solid radioactive waste storage area (BNI 56); ∙ the Phébus research reactor (BNI 92); ∙ the Laboratory for research and experimental fabrication of advanced nuclear fuels (Lefca – BNI 123); ∙ the Chicade laboratory (BNI 156); ∙ the Cedra storage facility (BNI 164); ∙ the Magenta storage warehouse (BNI 169); ∙ the Effluent advanced management and processing facility (Agate – BNI 171); ∙ the Jules Horowitz Reactor (JHR – BNI 172), under construction. ∙ Provence-Alpes- Côte d’Azur The Marseille division regulates nuclear safety, radiation protection and the transport of radioactive substances in the 6 départements of the Provence-Alpes-Côte d’Azur region. 127 inspections 5 significant events rated level 1 or higher In 2024, ASN carried out 127 inspections in the Provence‑Alpes‑Côte d’Azur region, comprising 60 in the Basic Nuclear Installations (BNIs), 60 in small-scale nuclear facilities, five in the area of Radioactive Substance Transport (TSR) and two concerning ASN-approved organisations and laboratories. During 2024, two significant events rated level 1 on the International Nuclear and Radiological Event Scale (INES) were notified by the nuclear installation licensees. In small-scale nuclear activities, two significant radiation protection events rated level 1 on the INES scale were reported to ASN, one in the industrial sector and one in the medical sector. One significant event in the area of TSR rated level 1 on the INES scale was notified to ASN. The installations and activities to regulate comprise: • Basic Nuclear Installations: • the CEA Cadarache research centre which counts 20 civil BNIs, including the Jules Horowitz Reactor (JHR) currently under construction, • the ITER installation construction site, adjacent to the CEA Cadarache centre, • the Gammaster industrial irradiator; • small-scale nuclear activities in the medical sector: • 13 external-beam radiotherapy departments, • 3 brachytherapy departments, • 16 nuclear medicine departments, • 86 centres practising fluoroscopy-guided interventional procedures, • 96 computed tomography scanners, • some 8,200 medical and dental radiology devices; • small-scale nuclear activities in the industrial, veterinary and research sectors: • about 400 industrial and research centres, including 3 cyclotron particle accelerators and 11 companies with an industrial radiography activity, • some 600 veterinary surgeries or clinics practising diagnostic radiology; • activities associated with the transport of radioactive substances; • ASN-approved laboratories and organisations: • 3 laboratories approved for taking environmental radioactivity measurements, • 3 organisations approved for measuring radon, • 2 organisations approved for radiation protection controls.
