Orano - Annual Activity Report 2024 201 SUSTAINABILITY STATEMENT 4 Social and societal information The group regrets the death of an employee of an external company in one of its car parks in circumstances unrelated to its activity. There were no fatal accidents among its employees in 2024. Objective 2025 Indicators (GRI 403-9) ESRS Reference 2019 2022 2023 2024 Progress Aim for the highest standards in health, safety and radiation protection with an accident frequency rate <1 Accident frequency rate with lost time (excluding commuting accidents) S1-14>88 c 1.8 0.9 1.2 1.07 Number of recordable work-related accidents with lost time (excluding commuting accidents) S1-14>88 c 0 29 43 37 Accident severity rate (accidents reported during the year, excluding commuting accidents) S1-14>88 c 0.08 0.04 0.06 0.08 Number of days lost due to workplace accidents or deaths due to workplace accidents involving employees S1-14>88 e n/a n/a n/a 2,399 Number of fatal accidents among Orano employees S1-14>88 b 0 0 0 0 Number of fatal accidents among external companies S1-14>88 b 1 2 0 1 n/a: not applicable. Indicator monitored since 2024 as required by the CSRD Directive. Methodological precision: Orano publishes work-related accidents with lost time, excluding commuting accidents. The accident frequency rate with lost time (excluding commuting accidents) is calculated per million hours worked. The hours worked used to calculate the frequency rate are the cumulative hours between December 2023 and November 2024. For the calculation, the group restates accidents with lost time from 2023 reclassified by the administrative authority. The number of days lost includes all days, excluding the day of the accident, including the first full day, the last day of absence and weekends. These indicators are calculated in accordance with the consolidation rules in force. They are based on actual data, without assumptions. Data for Niger subsidiaries are included until 30 November 2024, in accordance with the alignment with the financial statements. Radiation protection results The results of the individual and collective dosimetric assessments were stable compared to 2023. They now include all international entities. Indicators (GRI 403-7) Reference 2019 2021 2022 2023 2024 Average exposure of employees to radiation over 12 consecutive months (mSv) 0.84 0.86 0.78 0.59 0.63 Total individual external doses over 12 consecutive months due to radiation for Orano employees (H.mSv) 8,300 8,868 8,858 6,769 7,349 Total individual internal doses over 12 consecutive months due to radiation for Orano employees (H.mSv) 2,934 2,753 1,634 1,548 1,428 Average exposure of subcontractors to radiation over 12 consecutive months (mSv) 0.5 0.65 0.57 0.69 0.51 Orano employees over 14 mSv (internal Orano threshold) 40 0 0 0 0 Subcontractors over 14 mSv (internal Orano threshold) 3 0 0 0 0 Maximum dose for Orano employees (mSv) 15.9 12.2 11.9 12.1 11.5 Methodological precision: Due to the time needed to obtain the results of passive dosimetry analyses (also called reference dosimetry) and the annual schedule for reporting these data in the group’s reporting software, the annual results are always expressed from July 1 of year n-1 to June 30 of year n. (For 2024 results, data refer to the period from July 2023 to June 2024). The group is not aware of any significant radiation protection event that occurred in the second half of 2024. Calculation of the average dose (internal and external) for the group’s employees and subcontractors includes all persons being monitored, within the perimeter subject to the Euratom directive (maximum dose of 20 mSv per year), including those whose radiation dose is zero or undetectable. The subcontractors taken into account are those at Orano facilities and not those at activities carried out on the premises of customers. Since the 2024 financial year, the maximum dose has included activities in the United States. The indicators cover the entire scope of consolidation.
