Orano - Annual Activity Report 2025 97 RISK CONTROL AND VIGILANCE PLAN 3 Vigilance plan Furthermore, in accordance with Article L. 125-15 of the French Environmental Code, the group’s sites produce an annual public report that includes a Section dedicated to the prevention and mitigation of risks and inconveniences associated with regulated nuclear facilities (INB) concerning protected interests. These interests include the protection of nature and the environment as well as public safety, health, and sanitation. Crisis management system Orano has a robust crisis management system to manage emergency situations relating to the safety of the facilities, as well as their security, the health of employees and neighboring populations and the environment. Around 100 crisis management drills are conducted each year, in France and abroad, placing group employees and external contractors under the responsibility of Orano in diverse scenarios representing identified risks (industrial accident, nuclear safety accident, natural conditions, transport accidents, deterioration of the safety/health situation). To do this, Orano relies in particular on: ● the skills of trained operational teams, as well as the teams responsible for managing the projects; ● experts or specialists in various fields; ● HSE Departments present as close as possible to operations; ● an emergency preparedness organization; ● coordination of the business line networks, enabling in particular the sharing of information on achievements, best practices and events in order to prevent risks and promote improvement actions; and ● the General Inspectorate responsible for verifying compliance with the safety standards for nuclear operations as well as the organization and functioning of the crisis organization, both centrally and at the sites. The primary objective of these exercises is to train crisis management teams and, more broadly, to raise employee and external contractors’ (working on the sites) awareness on how to behave in the event of a crisis. They also enable the local, regional and national crisis organizations to test the relevance of the procedures they have established to control the situation and limit the impacts on individuals and the environment. Prevention of the risk of chemical or radiological environmental pollution from past activities of facilities Description of the risk The group’s past activities carried out in accordance with the environmental standards of their time, or incidents that have occurred, may have left historical environmental legacies that need to be managed as part of liability control. Risk prevention Orano maintains constant monitoring of its environmental performance and strives to reduce the environmental impact of its activities, for each of its operations and throughout their entire lifecycle. Environmental monitoring of nuclear operations and decommissioning strategy Orano conducts more than 100,000 measurements and analyses annually from approximately 1,000 sampling points to monitor the environment around its sites and mitigate the risk of harm to nature and neighboring populations. The results of these analyses provide in-depth environmental assessments of emissions’ impacts on air, water, and waste. They can be consulted on Orano’s website as part of the annual information report for each site, published under Article L. 125-15 of the French Environmental Code. Since February 2010, the public can consult the website managed by the ASNR (www.mesure-radioactivite.fr) to access all radioactivity levels in the environment and environmental monitoring reports conducted as part of regulatory surveillance around French sites. Each site is given the necessary tools to manage and submit the data. The group’s laboratories have obtained the required approvals from the ASNR for conducting their analyses. These approvals are renewed periodically following inter-comparison tests organised by the ASNR based on an analysis framework defined by the French National Environmental Radioactivity Measurement Network (Réseau national de mesure de la radioactivité de l’environnement, RNM) Decommissioning, remediation, and sanitizing are an integral part of the group’s responsibility approach with the following objectives: the nuclear sites are sustainable, the future use is industrial, the decommissioning is immediately after removal of nuclear materials and radioactive waste from operations, and the land remains the property of Orano except in special cases. In accordance with the regulations and the guidance of the French administrative authorities, the decommissioning strategy adopted by the group includes: ● the decommissioning of the INBs as quickly as possible, to ensure that personnel familiar with the facility are available and that they have a good understanding of the initial state of the facility to be decommissioned; ● the financial assessment of future expenses, determined well in advance and taking into account a certain number of internal and external contingencies and uncertainties; ● the management of the waste produced and, in particular, the identification of available channels, the management of storage facilities pending the availability of storage, the recycling of waste and the optimization of the volume of waste; and ● taking into account internal feedback or the national or international benchmark on the decommissioning of facilities. Structured governance within Orano makes it possible to define the strategy, assess expenses, and establish the corresponding provisions. This consists of an operational line and an independent control line. For each of the decommissioning plans, Orano describes the targeted decommissioning strategy, the main measures implemented, the planning of operations, the initial state of the facility, as well as the target final state. Decommissioning operations carried out on buildings and soils concern the decommissioning of all equipment, the remediation of premises and soils, the possible destruction of buildings not to be reused, and the recovery, packaging and disposal of waste.
