ORANO // Annual Activity Report 2024

SUSTAINABILITY STATEMENT

Environmental information

Radioactive waste results A high proportion of radioactive waste is produced at Orano sites abroad, in particular at the Cominak mining site (Niger), which is being dismantled and remediated. Mining waste contains only radionuclides of natural origin and is classi fi ed as very low-level waste (VLLW). Concerning production in France, the quantity of radioactive waste stored above ground (VLLW and LL-SLW and ML-SLW) is greater

than the quantity of waste intended for storage in the deep-sea centers (FAVL and Cigéo centers). The quantity of VLLW and LL-SLW and ML-SLW waste produced is in line with the quantity forecast at the beginning of the year. The quantities of HL and ML-LLW waste produced by Orano are very low and correspond to the production of waste related to the operation of used fuel processing and recycling facilities.

n/a: not applicable. The indicators required by the CSRD Directive are published from the 2024 fi nancial year. Methodological precision: The radioactive waste produced by Orano is waste produced in France and abroad. All data are expressed in m 3 .

In France, the radioactive waste produced corresponds to waste: • shipped to storage facilities in operation (CIRES and CSA), • stored on the sites and intended for the future storage centers under study (LLW-LL center and CIGEO centers), • for reasons of data availability for 2024 and by regularity of activity, the quantities of radioactive waste packages of categories MLW-LL and HLW produced are estimated on the basis of data for 2023. The following are excluded from the calculation: • waste stored on sites for which a channel has not yet been de fi ned because it represents a negligible quantity produced each year; • LLW-LL category waste because it is not produced by Orano; • waste sent for incineration at Centraco because incineration is a process prior to storage. Internationally, the radioactive waste produced corresponds to the waste produced by the Orano Mining sites. Excluded from the calculation are waste produced on behalf of foreign customers not belonging to Orano (Germany) and waste produced by Orano NPS in the United States because they represent a negligible quantity (less than a few cubic meters per year).

Financial effects of radioactive waste Orano is working to quantify the fi nancial effects of risks and opportunities concerning radioactive waste. The group plans to publish these within three years, in accordance with the phase

in provisions provided for by the standard. The fi nancial effects related to the dismantling of nuclear facilities and the recovery of waste are presented in Section 4.2.4.4.
