Methodological clarification: The volumes of water reported by the sites are generally obtained by readings on the meters in place, in particular for the volumes drawn, which make it possible to deduce the volume of water consumed. In some cases, estimates are required, for example for the volumes of recycled, reused, or stored water. The indicators have been recalculated to retroactively take into account the deconsolidation in 2024 of the Nigerien subsidiary Somaïr. All volumes include the 100% McClean transaction and the other Canadian JVs operated by Cameco at 0%, as described in the scope of consolidation. This method of calculating water consumption (CDP-ICMM definition), water withdrawal, and water discharge reduces the results by less than 15% compared to strict application of CSRD consolidation rules (McClean and Canadian JVs included at their percentage of financial consolidation). Water consumption includes that of Orano’s independent subcontractors whose activity is on-site and entirely dedicated to Orano. Water consumption (OECD definition): this is the quantity of water consumed specifically for the site’s needs, which implies a quantitative reduction in the resource (consumption in processes, products, waste, by employees, by an evaporation system and all losses) and/or qualitative (physical and chemical degradation). Water consumption (CDP – ICMM definition): this is the quantity of water consumed specifically for the site’s needs, which implies a quantitative reduction in the resource (consumption in processes, products, waste, by employees, by an evaporation system, and all losses) and that is not discharged to surface water/ groundwater or that is not sent to a third party for treatment (e.g. collective wastewater treatment plant) or consumption (e.g. mining cities if existing). The “Aqueduct” tool of the World Resources Institute’s water risk atlas (presence of sites in the High and Extremely High areas for the overall water risk data) makes it possible to define the areas subject to a water risk or high water stress. For 2025, the sites considered to be in an area subject to high water risk are: Orano Mining Namibia, Badrakh Energy and Katco. For 2025, no site is located in an area of high water stress. As with GHG emissions, the intensity is calculated in relation to the share of turnover linked to the activity (income from goods and services as presented in the consolidated income statement in Section 6.1).
