PAST RISK

RISK RELATED TO CHANGES IN SAFETY AND SECURITY REGULATIONS

Changes in regulations or demands on the safety and security of facilities and products generate investment needs. (increased vigilance of material storage authorities, post-Fukushima investments, etc. ). Regulatory changes in terms of the safety and security of facilities may generate investments and operating expenses that have a negative impact on the group’s results and cash flow. A nuclear or chemical accident at Orano facilities or within the industry would impact the group’s activity. The consequence of a major accident would be the impairment of the assets of the affected site, calling into question the group’s activity. Any serious event related to the group’s nuclear operations, having a potential or proven impact on the population, the environment or a region, could lead to a signi fi cant increase in the operating constraints of the group’s industrial sites, or even to a partial or total interruption of the group’s nuclear operations. Such an event could also have a signi fi cant negative impact on the health of employees, on the group’s fi nancial and legal position as well as on its reputation. Nuclear and industrial safety and security are the group’s priority. The group implements actions to prevent and mitigate the risks of nuclear or industrial accidents. Orano has a robust crisis management system to manage emergency situations. In addition, Orano’s facilities are regularly inspected by the competent authorities to ensure their reliability.
