Nuclear Defense safety, nuclear security, nuclear and chemical non-proliferation
Within a formalised conventional framework, IRSN provides support or technical aid to the DSND (Representative in charge of Nuclear Safety and Radiation Protection for Defense-related Activities and Facilities), the HFDS (Senior Defense and Security Officials) of the Ministry of Ecological Transition (MTE) and the Ministries of the Economy, Finance and Recovery (MEFR), and the EURATOM Technical Committee (CTE).
The missions entrusted to the Institute cover the fields of the nuclear safety of facilities and activities of interest to defense, protection against acts of malice, and the control of nuclear materials, facilities and transport (with the exception of the field of deterrence), as well as the application in France of the international treaties for combating the proliferation of chemical or nuclear weapons of mass destruction.
This comprises the technical appraisal of dossiers submitted by operators to the Authorities, the conduct of studies in disciplines such as cybersecurity or the effects of weapons and explosives, as well as various activities that are more directly operational, in particular supporting inspections designed to check compliance with the requirements linked to the international undertakings incumbent on France, keeping centralised accounts of nuclear materials, or monitoring the transportation of nuclear materials on national territory. IRSN also conducts studies or tests in partnership with specialised national or international organisations on personal protective equipment (PPE), in order to test the equipment’s capacities and vulnerabilities. In 2021, efforts were focused on the development of rapid pre-analysis tools for the effects of an explosion on a facility or during transportation, as well as on the reproduction of a command and control system for the application of cyber-attack intrusion tests.
