Autorité de sûreté nucléaire, the French nuclear safety authority
The Autorité de Sûreté Nucléaire is an independent authority in France that oversees all civil nuclear activities, from reactors to radioactive material storage. It conducts regular inspections, authorizes radiation use in medicine and research, and coordinates emergency drills at facilities.
The authority was created in 2006 to provide more independent oversight of nuclear power, and in 2024 merged with another research institute to become a single large organization. This consolidation further strengthened control of France's nuclear energy sector.
The authority oversees the safety of nuclear facilities and protects workers, the public, and the environment from atomic risks. Its mission is to ensure that everything operates without danger.
The authority is headquartered near Paris in Montrouge, with regional offices throughout France to stay close to the sites it monitors. Visitors can contact these offices for information about nuclear power plants and safety measures in their area.
The authority uses an international scale called INES to measure the severity of nuclear incidents and quickly assess whether a problem is serious. This system helps the public understand how dangerous a situation is.
