ASN Organisation



ASN comprises head office departments and eleven regional divisions with competence for one or more administrative regions. This organisation enables ASN to carry out its regulation and monitoring duties over the entire country and in the overseas territories of France.


The departments are organised thematically and manage national affairs concerning the activities for which they are responsible. The ASN regional divisions operate under the authority of the regional representatives, appointed by the ASN Chairman. They are ASN's representatives in the regions and contribute to the ASN's public information role. The divisions carry out most of the direct inspections on nuclear facilities, radioactive material transport operations and small-scale nuclear activities. In emergency situations, the divisions assist the préfet of the département, who is in charge of protection of the populations, and monitor operations to safeguard the installation on the site, provided that it is accessible and does not constitute a hazard.
