DEVELOPMENT OF EMPLOYMENT AND TRAINING IN THE REGIONS WHERE THE GROUP OPERATES

OWN OPERATIONS

The group’s companies are a leading employer in the regions, sometimes with a major economic weight. Orano supports local training and employment initiatives. Orano maintains a sustained level of recruitment and continues to set up vocational schools to guarantee the development and sustainability of skills.

POTENTIAL POSITIVE IMPACT

OWN OPERATIONS

RELOCATION OF ACTIVITIES IN THE COUNTRIES WHERE THE GROUP OPERATES

The development of new activities, expansion or relocation in the countries where we operate generates employment and direct and indirect economic bene fi ts. The activities are carried out in accordance with controlled social and environmental standards. The development of the group’s activities would contribute to the dynamism of the regions where it operates. It would strengthen their attractiveness by promoting the development of skills and employment, while actively engaging in local life around the sites.

Description

These four levels of defense, taken into account from the design stage of the facilities, are supplemented by a fi fth level comprising the organizational arrangements and the means implemented to manage emergency situations and protect the public. Improvement actions targeting the fi ve levels of defense in depth were carried out to take into account experiential feedback, such as lessons learned

4.3.3.2 Targetting the best standards in terms of the safety and security of our activities and products Nuclear and industrial safety and environmental protection policy and actions The safety and security of its operations and transport are a priority for Orano. It is one of its six values. Nuclear safety consists of all the technical, organizational, and human measures relating to the design, construction, operation, shutdown, and dismantling of regulated nuclear facilities, as well as the transportation of radioactive substances, taken to prevent accidents and limit their effects, and in general, to protect human and environmental health. It contributes to the fundamental human right to live in a healthy environment. These are based in particular on the principle of defense in depth, which is reflected in a series of risk management measures (“lines of defense”) aimed at preventing technical or human failures and limiting their impacts. Measures are thus implemented at four levels: ● prevention, which consists of building in, at the design, construction, and operating stages, intrinsic resistance to its own shortcomings and to attacks de fi ned a priori ; ● monitoring, enabling incidents to be detected, followed by implementation of actions to prevent them from leading to an accident, and fi nally, restoration of normal and safe operation; ● limiting the consequences in order to control accidental situations that could not be avoided or, failing that, limiting their aggravation by restoring the facilities and keeping them in a safe condition; and ● management of the most serious accidents to mitigate the consequences of accidents resulting from the failure of the third level of defense in depth.

from the Fukushima accident. Safety studies for facilities

Safety studies are carried out for each facility. The safety studies carried out for each facility take into consideration internal risks of nuclear (criticality, radiolysis, etc. ) and non-nuclear origin (chemicals, handling, fi re, etc. ) from the design stage, as well as external risks (tornado, earthquake, etc. ). The risks are reassessed every 10 years during the periodic review of each nuclear facility. These reviews, which are a regulatory obligation for regulated nuclear facilities (INB), enable a regular reassessment of the level of safety of an installation taking into account the latest regulatory changes and the best available techniques. In practice, they may include material modi fi cations to the facilities. The purpose of this exercise is to obtain the necessary approvals from the competent safety authority to continue operating a facility for the next ten years. Subject to ASN approval, each fi le is also sent to the competent minister. As in previous years, 2024 saw sustained activity in terms of periodic reviews, with investigations in progress on several sites. Nuclear and industrial safety in the HSE policy for 2024-2026 The Nuclear and Industrial Safety – Health – Occupational Safety – Radiation protection – Environment (HSE) policy for 2024-2026, approved by the Orano Executive Committee, formalizes the priorities for action in terms of nuclear and industrial safety and environmental protection. Its implementation is monitored by the Head of Health - Safety - Environment (HSE), a member of the Executive Committee. It is available on the group’s website.
