Orano - Annual Activity Report 2025 95 RISK CONTROL AND VIGILANCE PLAN 3 Vigilance plan In 2025, the Malvési site replaced its main compressed air compressor. This energy improvement project will reduce annual electricity consumption by 500 MWh, thereby helping to optimize the site’s energy performance. The objective of Orano la Hague, like that of the group, is to achieve a 10% improvement in energy performance by 2030 compared to 2019. The Energy performance plan implemented in 2021 has enabled a performance improvement of more than 7%, representing a sustainable saving (excluding production and weather effects) of 48 GWh per year compared to 2019. Half of these results are due to improvement projects such as the installation of LEDs, the shutdown of superheated water during certain periods, the replacement of motors such as those used in ventilation systems, and eco-driving of facilities. The other part mainly involves implementing a new steam production strategy based on a mix of fuel oil and electric boilers. The la Hague site has also been ISO 50001 certified since 2022, an international standard that helps organizations improve their energy performance by implementing an energy management system (EnMS). Eco-performance and circular economy In recent years, Orano has renewed part of its production capacity and now operates unique facilities in their category across many of its sectors. These renewals have also led to improvements in terms of safety and the environment, thanks to the choice of the best available technologies. The investments in new technologies induced by these objectives and the eco-performance approach initiated in 2004 have helped Orano achieve significant results in terms of reducing its environmental footprint. Since 2004, the group has reduced its greenhouse gas emissions by 80% (scopes 1 and 2 market-based). In order to minimize its environmental footprint, Orano continues to implement targeted actions at its facilities to reduce extraction from natural environments and the consumption of materials and energy by constantly seeking ways to recover waste. Thus, for the renovation and commissioning of its new facilities on the front end of the cycle, the best available technologies are adopted, considerably reducing the abstractions, consumption, and emissions from these activities. In 2025, the group strengthened its eco-design approach by updating its eco-design roadmap for 2025-2030. This roadmap is driven by a dedicated project team and includes the deployment of a methodology for assessing environmental issues. At the end of 2025, 76% of projects exceeding 20 million euros followed this approach. An eco-design network, made up of officers in the group’s various Business Units, has also been created with the aim of further anchoring the eco-design culture and capitalizing on feedback. Orano also contributes to the circular economy by recycling spent nuclear fuel in its la Hague and Mélox facilities in order to reduce both the volume and radioactivity of the most radioactive waste. Through the processes of extracting and separating recyclable materials (uranium and plutonium) in la Hague, chemicals that are used during the operations are recovered and reused. Through its know-how in the recycling and recovery of strategic metals, Orano is exploring new areas of business and is thus developing an electric vehicle battery recycling project. Orano also promotes reuse via its “Nuclear Market Place” platform, allowing the sharing of industrial equipment in the form of lease/loan or sale/donation between players in the French nuclear industry. Prevention of risks related to radioactive waste management Description of the risk The operating, decommissioning and sanitizing activities of the group’s nuclear facilities may generate radioactive waste that could present a risk to the environment and surrounding populations. Risk prevention These risks are classified based on the level of their radiological activity (in accordance with the levels usually applied: very low, low, medium, or high), and the lifespan of the radionuclides they contain (very short, short, or long). To address this, Orano dedicates a significant part of its duty of vigilance to the management and treatment of radioactive waste. Once again, Orano’s strategy is monitored and controlled by the ASNR. Waste management in accordance with national and European requirements Orano aligns its radioactive waste management methods with the principles outlined in the French Environmental Code which include: ● protecting public health, safety and the environment; ● preventing and limiting burdens on future generations; ● reducing the quantity and harmfulness of radioactive waste, in particular by using appropriate processing and packaging methods; ● organizing waste shipments and limiting them in distance and volume; and ● providing information to the public on the environmental and public health effects of waste production and management operations, subject to confidentiality rules provided in the law, and on the measures taken to prevent or offset harmful effects. Each step of radioactive waste management is characterized by actions to be carried out in compliance with these golden rules: ● have a formal and up-to-date framework; ● comply with, apply and adapt the waste management guidelines; ● limit waste generation; ● limit the harmfulness of waste; ● select the most appropriate waste management method; ● reduce the volume of conditioned waste; ● remove waste promptly; ● ensure good waste storage conditions; ● evacuate as soon as possible; and ● promote continuous improvement in waste management practices.
