It ensures that all employees have access to medical care adapted to their activity. It aims to extend the level of prevention evenly to external companies and works proactively on the prevention of diseases. However, the group has not set any quantitative targets in this area.

With regard to occupational safety, the group has set itself the goal of ensuring that the accident frequency rate for employees is less than or equal to 1 in the long term. This objective is voluntary. In terms of radiation protection, Orano aims for a dose below 20 mSv in accordance with regulations and has set an internal alert threshold at 14 mSv. Targets are developed internally with operational teams and shared in France minimum once a year with employee representatives in dedicated bodies. The results are also shared.
