Orano - Annual Activity Report 2025 148 4 SUSTAINABILITY STATEMENT Environmental information DESCRIPTION OF ACUTE AND CHRONIC PHYSICAL RISKS AND MAIN ADAPTATION LEVERS Area of activity Extreme phenomena (extreme temperature, heavy rain, storms, flooding) Main adaptation levers Plants Increased extreme temperature events and intense precipitation, especially in the Mediterranean region ● Fuel cycle plants: risks of a fall in production or temporary shutdowns (sites in the south of France, in particular) ● Difficulties in cooling certain facilities identified ● Increased risk of a violent Mediterranean episode with flooding and damage to the effluent basins of the establishments concerned ● Resizing of water management systems (dry period and violent Mediterranean episode) Mining ● Sharp increase in extreme heat peaks at the Canadian and Kazakh sites (+3°C for maximum temperatures according to the RCP 8.5 in 2050), and an increase in the intensity of extreme precipitation events ● Risks of a fall in production or temporary shutdown of sites (loss of electricity supply, breakdown and loss of production equipment, flooding, and damage to dikes or wastewater basins, etc.) ● Specific studies of resilience to climate hazards ● Resizing of water management systems Suppliers ● Significant delays and disruption in the supply of manufactured or chemical products, particularly from certain suppliers ● Monitoring of vulnerabilities and adaptation of strategic suppliers ● Geographic diversification of supplies ● Integration of an outsourced activity in the event of a mismatch Radioactive material flows ● Logistical difficulties (destruction of roads, traffic interruption, disruptions) related to inclement weather and heat peaks that threaten road and rail traffic ● On the roads used, the increase in maximum temperatures is +5°C in North America, +4.4°C in Central Asia, according to the RCP 8.5 in 2050 ● Risk of partial or total unavailability of ports (flooding by tides during storms) ● Diversification of logistics routes ● Specific studies on transport conditions
