Jean-Luc Lachaume, Executive Director for Emergency Response at IRSN, is appointed to the ASN Commission


By decree of the President of the Republic dated 21 December 2018, Jean-Luc Lachaume is appointed ASN Commissioner* for a period of 6 years. He succeeds Margot Tirmarche, whose mandate expired on 12 November 2018.


Since September 2017, Jean-Luc Lachaume was Executive Director for Emergency Response at IRSN. Jean-Luc Lachaume's mission was to coordinate crisis activities, and to strengthen the representation of the Institute's crisis management with national and international institutions.

From 2006 to 2017, Jean-Luc Lachaume was Deputy Director General of ASN in charge of the regulation and control of fuel cycle facilities, research reactors, medical and industrial radioactive sources and radioactive waste. Specifically responsible for overseeing emergency preparedness activities, Jean-Luc Lachaume was also very involved in international issues related to the activities of the IAEA and the NEA and to ASN's bilateral relations.

Jean-Christophe Niel, Director General of IRSN, welcomes the appointment of Jean-Luc Lachaume as ASN commissioner. "This appointment is recognition of the fundamental and unavoidable role of IRSN in France. I would like to acknowledge the commitment of Jean-Luc Lachaume was Executive Director for Emergency Response, within the Institute. During these last months, he put all his expertise at the service of our capacity to manage a nuclear crisis, his knowledge and his experience of nuclear safety and radiation protection will be strong assets in his new functions."


* The ASN Commission is composed of five commissioners, including the ASN Chairman, appointed for six years. By law, the members of the Commission act with complete impartiality, receiving no instructions from either the Government or any other person or institution. They exercise their functions on a full-time basis and their mandate is neither renewable nor revocable.

The Commission develops the ASN strategy and doctrine for the regulation of nuclear safety and radiation protection. It issues resolutions embodying the most important decisions. It takes public positions on the major issues that lie within the competence of ASN. It reports to the French Parliament.
