LES ACTIVITÉS NUCLÉAIRES : RAYONNEMENTS IONISANTS ET RISQUES POUR LA SANTÉ ET L’ENVIRONNEMENT ASNR also inspects manufacturing facilities to maintain a presence on the ground and ensure the adequacy of the monitoring of the subcontractor supply chain put into place by the licensees and manufacturers and, more particularly for the NPE, to check the quality of manufacturing at the regulated manufacturers and their subcontractors. As such, a significant number of inspections are carried out abroad, particularly as part of the procurement of equipment for the EPR 2 project. 6.3 Review 2025 The results of the inspections carried out by ASNR in 2025 are shown in Table 13. 6.4 Support initiatives at national level ASNR engages in regular dialogue with nuclear industry representatives in order to explain the regulations, to develop changes made to the technical baseline requirements of the ordering parties, and share best practices and ways of improving safety. ASNR in particular wishes to see improvements in suppliers’ and their subcontractors’ understanding of the regulatory requirements and increased traceability of activities important for the manufacture of equipment important for the protection of interests. This traceability is notably based on improved computerisation of manufacturing monitoring, which is insufficiently developed among certain companies in the sector. These discussions were in particular held with representatives of the sector within the French Nuclear Energy Industry Players Group (GIFEN). In 2024, ASNR published a practical guide in French and English, intended for the suppliers of equipment for nuclear facilities, and their subcontractors. The purpose of this practical guide is to make the regulations and their objectives more accessible. It explains the design and manufacturing requirements for safety-important equipment, as well as the industrial practices that ASNR considers to be satisfactory. The principles described are illustrated by industrial examples, with a resolutely practical approach. To draft it, in-depth technical exchanges were held with the GIFEN. 6.5 International collaborations ASNR is continuing and strengthening its international commitment to overseeing the supply chain for nuclear facilities, by actively participating in the work of international bodies, in particular the Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). As such, ASNR is particularly involved in the NEA’s Committee on Nuclear Regulatory Activities (CNRA), through active participation in the Working Group on Supply Chain (WGSUP), which ASNR chairs, and the Expert Group on Operating Experience (EGOE), which ASNR vice-chairs. As part of the WGSUP, which brings together international organisations and inspection authorities, participants discuss the lessons learned from inspections and the findings and conclusions drawn from in-plant inspections. These exchanges help to draw the attention of the safety authorities, licensees and suppliers to the areas most at risk and to alert all stakeholders to the issues likely to affect safety. In 2025, ASNR’s participation in the work of WGSUP resulted in several international actions in cooperation with our foreign counterparts: ∙The UK Office for Nuclear Regulation (ONR) carried out an inspection of a supplier based in France, which ASNR inspectors attended as observers. This approach has made it possible to share the findings of the inspection and to strengthen exchanges on control practices. ∙ASNR was represented at the IAEA Technical Meeting on the supply chain, which brought together licensees, industry representatives and regulatory authorities. This Technical Meeting provided an opportunity to present the supply chain control and support mission. 0 10 20 30 40 50 60 Licensee Private Institutional University Association Total 37 53 15 30 37 43 35 44 34 38 1 3 3 2 2 4 2 5 1 4 2 5 1 5 2 3 4 4 10 10 28 18 7 Foodstuffs Ambient environment Gas / Air Aerosols / Filters Biological Soil Water GRAPH 11 Approved laboratories per type of matrix as at 1 January 2026 Type of equipment checked Number of inspections Of which in plants (excluding sites in operation) Of which abroad NPE 61 40 17 PIC, including nuclear fuel 36 26 2 Transport packaging 8 8 6 Manufacturers and distributors of radioactive sources 29 – 2 TABLE 13 Summary of inspections carried out by ASNR in 2025 170 ASNR Report on the state of nuclear safety and radiation protection in France in 2025
