ASNR Report 2025

LES ACTIVITÉS NUCLÉAIRES : RAYONNEMENTS IONISANTS ET RISQUES POUR LA SANTÉ ET L’ENVIRONNEMENT As well as raising awareness of the risks involved, scientific outreach activities are carried out for young people and schoolchildren, to provide them with information about radioactivity, its uses and its effects on health and the environment. This year, to mark the Fête de la science (science festival), ASNR teams took part in seven events organised across the country – including in French Polynesia. At its Le Vésinet site, ASNR ran an open weekend that attracted nearly 1,000 visitors and schoolchildren. Educational workshops, tours, lectures, games and exhibition presentations took place over the two days. Other educational initiatives were carried out in 2025, such as Déclics (Dialogues Between Researchers and High School Students to Interest Them in the Building of Knowledge), organised by the Cercle FSER. Its objective is to introduce the world of research to pupils at Jacques Monod high school in Clamart. For half a day, the high school students discovered the inner workings of the scientific processes and the diversity of the professions that contribute to them. ASNR also took part in a number of “Science in questions” programmes on the effects of radiotherapy and the risks of fire in a NPP. To support these initiatives to prevent radiological risks and develop a culture of radiation protection among young people, and to encourage dialogue between science and society, in 2025 ASNR established a new partnership with the French Institute of Trainers for Major Risks and Environmental Protection (Iffo-RME). Dialogue with civil society Dialogue with civil society is a pillar of ASNR. It is based on transparency and the sharing of information, enabling the public to develop an informed opinion, as well as on their participation in expert appraisal and research projects, and in decision-making and monitoring activities. ASNR has a specific department dedicated to dialogue but, in line with previous IRSN and ASN initiatives, all the various departments are involved, particularly the regional divisions thanks to their local roots. ASNR engages in dialogue with many partners in civil society, first and foremost with the CLIs and their national association Anccli (see point 1.5.4), made up of elected representatives, trade union representatives, non-profit organisations and qualified individuals, as well as with other organisations (environmental or patient associations, for example) and any stakeholder in society interested in nuclear safety and radiation protection issues. In terms of activities, examples include technical dialogues and consultations, notably on the Cigéo project, as well as on the reviews of the 900 and 1,300 MWe reactors. A day of experience-sharing 2. A "serious game" is a game that has a primary purpose other than entertainment. Serious games are a mixture of serious content and a video-game-style scenario. The aim is to make the serious content being conveyed more engaging through the use of formats, interactions, rules and potentially fun objectives. was co-organised with Anccli on the theme of involving civil society in environmental monitoring. This dynamic was reinforced by the creation of environmental representatives within the CLIs. In addition, a new radiological site survey was launched in March 2025, in which local stakeholders around the Ecarpière site will now be able to participate. The ORRCH-IDEes participatory research project on multi-exposure brought together members of the public and voluntary organisations in the Dunkerque area for three collective discussion workshops and three meetings between researchers and members of the public, with the aim of collectively formulating research questions (see Highlight No. 2). The Local Nuclear Information Committee (CLIN) of Blayais took part in the review inspection of the EDF Le Blayais NPP in June 2025. Finally, still in the Blayais area, a feedback session was organised for the CLIN and participants in the participative workshops which featured a serious game(2), as part of the Demeterres Mousse project (see chapter 4, Highlight No. 1). The year 2025 was also marked by numerous requests from CLIs, voluntary organisations and local players. Some of these resulted in presentations by ASNR at meetings, sometimes in public, and to knowledge-sharing initiatives, such as the training days on the main principles of Pressurised Water Reactor (PWR) safety for the CLIs at Dampierre-en-Burly in March, and at Blayais and then Golfech in June, as well as public meetings on radon risk management in the Pyrénées-Atlantiques region in conjunction with the Regional Health Agency (ARS) and the three Permanent Centres for Environmental Initiatives (CPIEs) in the Basque Country and Béarn. ASNR also systematically responded to numerous requests for technical information received in writing from associations and CLIs. Lastly, in 2025, ASNR's good practice in involving stakeholders in expert appraisal and decision-making processes was shared internationally, in particular within the NEA at the 4th Stakeholder Involvement Workshops (SIWS), the Stakeholder Confidence Forum and as part of the European EURAD2 project. In order to guarantee a continuous engagement by society through integrating all of ASNR's missions, ASNR has decided to draw up a roadmap for its policy on dialogue with society. Work on this has been underway since the beginning of 2025, building on the legacy of previous initiatives undertaken by IRSN and ASN, and taking into account the recommendations of a dedicated HCTISN working group and the conclusions of a series of discussions between the Commission and leading figures in the field of participation and organisations involved in dialogue with civil society. BAROMÈTRE 2025 LA PERCEPTION DES RISQUES PAR LES FRANÇAIS LES GRAPHIQUES HIGHLIGHT No. 1 Survey of French people's perception of risk ASNR has published its 2025 barometer on French people's perception of risk. It presents changes in this perception along four main lines: the main concerns of the French, their view of science and expertise, their perception of risk situations and their opinion on radiation protection, energy and nuclear safety. This edition highlights a number of lessons. The French have high expectations of nuclear safety: 83% said that “operators of nuclear sites must protect their facilities from all risks, even those deemed highly unlikely”. The development of research into the safety of existing reactors and the strengthening of inspections by the competent authorities top the list of measures proposed to reinforce the safety of nuclear installations. 130 ASNR Report on the state of nuclear safety and radiation protection in France in 2025
