Orano - Annual Activity Report 2024 185 SUSTAINABILITY STATEMENT 4 Environmental information of the ALARA principle, a risk reduction approach at source is implemented (limiting the hazardous nature of the substances used, limiting the quantities stored, etc.) whenever possible. Active consequence mitigation systems must be implemented and integrated into incident management systems. Nuclear safety and industrial security systems are detailed in Section 4.3.3.2. 4.2.4.3 Targets and results related to the management of liabilities The group monitors the progress of dismantling by facility. There is no consolidated indicator at group level, nor any group quantified target in this area. As part of its new roadmap, Orano aims to finalize two symbolic remediation actions by 2030: the deconstruction of the air-cooling towers of Georges Besse I on the Tricastin site and the end of the clean-up of the park adjoining Orano la Hague. This objective contributes to the reduction of the risks identified in the materiality analysis. The demolition of all air-coolers began at the Tricastin site in 2024. Orano Mining has set targets for the management of mine tailings and site remediation for 2030: ● move towards passive management of tailings storage for new mining sites; ● bring all ore processing tailings storage facilities into compliance with the GISTM Standard and disclose annually from August 2025, for each site, the reports on compliance with the Standard. This objective is part of the overall approach to preventing accidental spills described in Section 4.3.3.2. It helps reduce the probability of an accidental spill and the risks identified in the materiality analysis. In 2024, the group did not report any major environmental pollution incidents (ASSESS level 4 or higher).

The cost-related indicators from the CSRD directive are required from financial year 2024. Methodological precision: Orano defines a major environmental pollution incident as a level 4 or 5 event on its internal ASSESS scale (see Section 4.3.3). The group has not suffered any to date. Provisions for environmental protection and clean-up costs include end-of-lifecycle provisions falling within the scope of the law and the provisions for the remediation of mining sites described in Section 4.2.4.4. 4.2.4.4 Financial effects related to the management of liabilities Very restricted financing of dismantling of regulated nuclear facilities and highly regulated waste recovery facilities Article 20 of French law No. 2006-739 of June 28, 2006 on the program for the sustainable management of radioactive materials and waste establishes the principle of the creation, by the operators of regulated nuclear facilities (INB), of assets earmarked to cover the costs of dismantling their facilities and managing the back end of the fuel cycle, in accordance with terms and conditions guaranteeing the availability of the necessary resources. The law provides for a mechanism to ensure that INB operators have the assets necessary to finance the long-term expenses related to the dismantling of these facilities, the management of used fuel and radioactive waste. In accordance with Article L. 594-4 of the French Environmental Code, Orano prepares a report every three years on future expenses for the dismantling of regulated nuclear facilities and legacy waste retrieval and packaging, and long-term management of radioactive waste packages. This report was updated in June 2022 and the update note reviewed in June 2023. At December 31, 2023, the group’s gross undiscounted future expenses amounted to 16,404 million euros, of which 95 million euros is borne by third parties. The obligations of the la Hague facility represent more than 72% of these end-of-lifecycle expenses. The amount of provisions falling within the scope of the Law at December 31, 2023 was 8,156 million euros in present value, including 80 million euros financed by third parties (Note 13 to the consolidated financial statements). These amounts include the costs related to the long-term management of radioactive waste, the volumes of which are indicated in the table below and broken down between waste already produced and future waste relating to the dismantling of INBs.
