ASNR Report 2025

LES ACTIVITÉS NUCLÉAIRES : RAYONNEMENTS IONISANTS ET RISQUES POUR LA SANTÉ ET L’ENVIRONNEMENT BNIs 33, 38, 47 and 80 at the La Hague site have been significantly postponed. ASNR also considers that Orano should continue to improve its knowledge of the current state of the facilities and notably the soils, with a view to future Post-Operational Clean-Out (POCO), and make progress in enhancing the industrial reliability of the waste retrieval processes. At the end of 2025, ASNR informed Orano of its expectations concerning the forthcoming update of the strategy for decommissioning and management of materials and waste, expected in mid-2027. 4.3 Assessment of CEA’s decommissioning strategy Given the number and complexity of the operations to be carried out for all the nuclear facilities concerned, CEA is giving priority to reducing the “dispersible inventory(4)” which is currently very high in certain facilities, particularly in some of the individual facilities of the Marcoule DBNI and in BNIs 56 and 72. In their Position Statement Letter of 27 May 2019, ASN and the ASND considered that, given the resources allocated by the State and the large number of facilities undergoing decommissioning for which legacy waste retrieval and storage capacity will need to be built, it was acceptable for CEA to envisage staggering the decommissioning operations and that priority be given to the facilities with the greatest safety risks. However, ASNR notes that, six years later, the identified difficulties persist, and that very significant drifts are observed in the Waste Retrieval and Packaging (WRP) schedules presented by CEA, particularly the pushing back of waste management deadlines, including for operations considered to be priorities. Some of these operations are effectively being reconsidered in depth after encountering deadlocks in the initially planned operations, or the late discovery of a facility state that is inconsistent with the expected state. ASNR and CEA have set up regular monitoring of these operations, notably by means of progress indicators. 4. Part of the inventory of the radionuclides of a nuclear facility that groups the radionuclides that could be dispersed in the facility in the event of an incident or accident, or even, for a fraction of them, be released into the environment. ASNR observes moreover that CEA’s decommissioning and materials and waste management strategies share certain vulnerabilities in particular relative to the availability of support facilities, which are often unique but are needed in order to run numerous projects (see section 2.3 of chapter 13 on radioactive waste management). CEA’s strategy is based on pooling resources between its centres and relies on the use of facilities, some of which are in the planning stage, in the commissioning phase, or undergoing renovation. The absence of an operational alternative in the event of the unavailability of these facilities is a major fragility factor for the programme as a whole. At the end of 2025, ASNR informed CEA of its expectations concerning the forthcoming update of the strategy for decommissioning and management of materials and waste. ASNR stresses the importance of guaranteeing the continuity of the most safety-critical operations, in particular those aimed at reducing dispersible inventories in the facilities with the greatest risks, such as BNI 56. It considers that maintaining a sustainable programme and sufficient visibility regarding the financial resources made available to CEA is an essential factor in controlling risks in the medium term. 352 ASNR Report on the state of nuclear safety and radiation protection in France in 2025
