The Autorité de sûreté nucléaire (English: Nuclear Safety Authority, ASN) is an independent French administrative authority set up by law 2006-686 of 13 June 2006 concerning nuclear transparency and safety. It has replaced the General Direction for Nuclear Safety and Radioprotection. Its task, on behalf of the State, is to regulate nuclear safety and radiation protection in order to protect workers, patients, the public and the environment from the risks involved in nuclear activities. It also contributes to informing the citizens.

From 2006 to 2012, the president of the ASN was André-Claude Lacoste[1] who was also a founding member and had been chairman of the International Nuclear Regulators' Association (INRA) and the Western European Nuclear Regulators' Association (WENRA).[2] He was also the chairman of the Commission on Safety Standards (CSS) of the IAEA.

Since November 2012, the president of the ASN is Pierre-Franck Chevet.[3]

During the events regarding the Fukushima I nuclear power plant, the ASN stated that they believed the events unfolding should be rated a 5 or even a 6 on the International Nuclear Event Scale when the Japan Atomic Energy Agency had listed them a day before as a level 4 event. Later on they said they believed the situation had surpassed that of a level 5 event and moved to a level 6. Their opinion was shared by the Finnish nuclear authorities.[4]
