Annual Activity Report 2025

Orano - Annual Activity Report 2025 104 3 RISK CONTROL AND VIGILANCE PLAN Vigilance plan Local Information Commissions (LIC) In view of the operational context of each of the sites where it operates, the group is involved in dialogue with local populations and stakeholders. In France, the group has long maintained regular dialogue with local stakeholders, through local information commissions (“commissions locales d’information” or LICs) and Site Monitoring Commissions (SMCs). In accordance with the regulations in force, the LICs are responsible for general monitoring, information and consultation in matters of nuclear safety, radiation protection and the impact of nuclear activities on individuals and the environment. They are composed of representatives of local authorities, local elected Members of Parliament, representatives of environmental associations, labor unions and qualified individuals. Representatives of the ASNR and the relevant State services and operators fully participate with a consultative vote in the work of the LIC. For example, the LIC on Large Energy Facilities in Tricastin (LICGEET), shared with the operator EDF, is chaired by the President of the Departmental Council of Drôme. LICGEET is responsible for safety, security, environment and radiation protection. At least two plenary meetings attended by the press are held each year, as well as one public meeting. Working groups are also set up depending on the subjects on which LICGEET is called. LICGEET’s minutes are public. The MarcouleGard LIC examines the activities of the four nuclear operators at the Marcoule site: CEA, Orano, Cyclife and Steris. It thus offers elected officials and local residents a consolidated view of the site’s activity. The equivalent exists at any “high-threshold” Seveso chemical industrial facility. The Seveso Site Monitoring Commission (SMC) is responsible for promoting information to the public about the facility’s activities. For example, the Malvési SMC meets at least once a year under the authority of the prefecture. The minutes of these meetings are also public. The same approach of dialogue is systematically applied to the group’s industrial sites abroad, such as Orano Mining’s sites in Mongolia, Kazakhstan, Canada, Namibia and Uzbekistan. A mechanism for managing complaints from local stakeholders has been in place at the group’s mining sites since 2021. This system facilitates the operational handling of complaints and provides for their handling within a reasonable timeframe, while keeping the complainant informed throughout the process. Sites open to the public In October 2025, Orano organized its fourth edition of the National Resilience Day. The group continues to organize visits to its sites and its emergency management resources by stakeholders, in particular elected officials, local news commissions and journalists. National Resilience Day has become an annual event for raising awareness and providing information, both internally and externally. The aim is to ensure that everyone is aware of the risks in their area, knows how to behave in the event of an incident, and becomes a key player in their own safety. For five years, the Malvési site has opened its doors to all stakeholders by creating a new event, “Malvési Wednesdays” (Les mercredis de Malvési). More than 1,000 individuals, including 220 in 2025, have visited the Malvési site in groups of around 10 individuals. A specific session was also organized in 2025 for the deaf and hard of hearing, with the intervention of a French Sign Language (LSF) interpreter. This initiative is part of a transparency approach and reflects the group’s desire to increase knowledge of its activities and the health and safety conditions at its sites, in particular to local populations. Dialogue bodies with major suppliers In order to maintain regular dialogue with its key partners, i.e. around 80 companies in France, the group organizes annual business reviews conducted by the purchasing market managers. These meetings follow a structured agenda built around fifteen key themes governing the commercial relationship, including in particular safety indicators and CSR criteria. Detached from strictly operational matters, these forums provide a shared, overarching perspective with partners’ executive teams, enabling the collaboration to be steered towards a dynamic of mutual value creation. In 2025, Orano organized two days dedicated to its partners at its industrial sites in la Hague and Tricastin. These events brought together the group’s main suppliers and subcontractors, as well as a wider range of stakeholders, such as the Chambers of Commerce and Industry and the local associations in which the group participates. The objective was to communicate on the group’s projects and expectations, and to refine its contribution to the industrial development of the regions in which it operates. It was also an opportunity for Orano to reiterate its commitments in the area of responsible purchasing. 3.4.2.5 Subcontractors and suppliers: choice of responsible partners As part of its activities, the group joins its expertise and knowledge with external companies that contribute to its industrial and economic performance and with whom it maintains a close relationship. A demanding and informed choice of suppliers and subcontractors The group’s Supply Chain Department attaches particular importance to the selection of its suppliers and subcontractors. It works in close collaboration with the HSE, Legal, Risks, Compliance and Internal Audit Departments to ensure that suppliers and subcontractors meet compliance requirements relating in particular to the prevention of corruption and influence peddling and those relating to the application of the law on the duty of vigilance. Responsible Purchasing Policy As an extension of its social and environmental commitments, the group formalized its Responsible Purchasing policy in 2024.
