[en] Further to Act No. 2015-992 of August 17, 2015 on energy transition for green growth, the legislative part of the French Environment Code defines the missions of the French Institute for Radiological Protection and Nuclear Safety (IRSN), the public expert in nuclear and radiological risks, together with those of the French Nuclear Safety Authority (ASN), and of the local information commissions (CLI). Decree No 2016-283 of March 10, 2016 on IRSN, which implements the Act, places the organization under the joint supervision of the Ministers for Ecology, Defense, Energy, Research and Health. IRSN is the national public expert in nuclear and radiological risks, and its activities cover all the related scientific and technical issues in France and in the international arena. Its work therefore concerns a wide range of fields, including environmental monitoring, radiological emergency response, radiation protection and human health in normal and accident situations, prevention of major accidents, and safety and security of nuclear reactors, plants, laboratories, transportation, and waste. It also carries out assessments in the nuclear defense field. In addition, IRSN contributes to government policy on health, nuclear safety, the environment and emergency response. Within this context, it interacts with all the organizations concerned including public authorities, in particular the nuclear safety and security authorities, members of the French parliament and local elected officials, research organizations, and stakeholder associations. IRSN also contributes to training and providing public information about nuclear and radiological risks. This document is the annual and financial report of the IRSN for 2018
