Occitanie The Bordeaux and Marseille divisions jointly regulate nuclear safety, radiation protection and the transport of radioactive substances in the 13 départements of the Occitanie region. In 2025, ASNR carried out 120 inspections in the Occitanie region, comprising 62 in Basic Nuclear Installations (BNIs), 49 in small-scale nuclear activities, 4 in the field of Radioactive Substance Transport (RST) and 5 concerning ASNR-approved organisations and laboratories. ASNR also carried out 16 days of labour inspection at the Golfech Nuclear Power Plant (NPP). During 2025, 3 significant events rated level 1 on the International Nuclear and Radiological Events Scale (INES scale) were reported by the NPP licensees of the nuclear installations in the Occitanie region. In the area of small-scale nuclear activities, 1 significant event classified at level 1 on the INES scale was reported to ASNR in the medical field. 120 inspections 4 significant events on a level greater than or equal to 1 on the INES scale 0 significant event of level 2 or higher on the ASN-SFRO scale Golfech nuclear power plant The Golfech NPP, operated by EDF is located in the Tarn‑et‑Garonne département, 40 km west of Montauban. It comprises two Pressurised Water Reactors (PWRs), each of 1,300 Megawatts electric (MWe), commissioned in 1990 and 1993. Reactors 1 and 2 constitute BNIs 135 and 142 respectively. ASNR considers that the performance of the Golfech NPP with regard to nuclear safety, environmental protection and radiation protection is in line with ASNR’s general assessment of the EDF plants. In the field of nuclear safety, ASNR considers that performance remains stable at a fairly satisfactory level, in the context of very sustained industrial activity, with two reactor outages, including the ten-yearly outage of reactor 2. There is still room for improvement in the operation of the facilities, particularly in terms of control room supervision. ASNR has given the site’s independent safety organisation a favourable assessment. The handling of deviations is also satisfactory; however, there are still weaknesses in the integration of operational experience feedback and in the questionand-answer approach to problem solving. In terms of maintenance, the successful completion of the reactor containment test on reactor 2 and the replacement of the pressuriser surge line demonstrate rigorous management, despite a few shortcomings during the work, particularly in terms of preventing the Foreign material exclusion risk, where the licensee needs to make sustained improvements. In addition, fire risk management, including the control of fire loads, needs to be improved. Finally, ASNR notes an improvement in preparedness for emergency situations. Radiation protection is judged to be fairly satisfactory, but has deteriorated slightly. On the one hand, ASNR notes the robustness of the radiation protection organisation and the good control of the risk of contamination spreading. In addition, worker radiation protection culture is inadequate, as shown by certain significant events, the exceeding of dosimetric targets and significant failings during radiographic controls. ASNR therefore expects particular vigilance in order to limit occasional deviations and reinforce compliance with radiation protection rules by everyone. Environmental protection is judged to be satisfactory, and is progressing compared with the previous year, with continued action on the containment of liquid pollution and the demineralisation plant. However, ASNR expects the licensee to take better account of the risks associated with chemical substances. Despite satisfactory management, waste management is not up to scratch. With regard to labour inspection, the results concerning occupational safety are stable compared with 2024. The risk of falling from a height is still a major concern, and there is still room for improvement. The relevance of risk analyses, the preparation of activities and their organisation need to be improved. In particular, two events took place involving the cutting of high-voltage electrical cables. Lastly, more needs to be done to ensure that facilities comply with the requirements of the Labour Code. Marcoule platform The Marcoule nuclear platform is situated to the west of Orange in the Gard département. Its six civil installations are dedicated to research activities relating to the back-end of the “fuel cycle” and the irradiation of materials, and to industrial activities concerning in particular the fabrication of MOX (Mixed OXides) fuel, the processing of radioactive waste and the irradiation of materials. The majority of the site moreover consists of the Defence Basic Nuclear Installation (DBNI) under the oversight of the Ministry of Defence. 82 ABSTRACTS – ASNR Report on the state of nuclear safety and radiation protection in France in 2025
