Enhancing Nuclear Safety
IRSN – Institute for Radiological Protection and Nuclear Safety – is
the French national public expert in nuclear and radiological risks.As a research and expert appraisal organization, IRSN contributes to the implementation of public policies concerning nuclear safety and security and health and environmental protection against ionizing radiation.
IRSN contributes to the safety of existing and future nuclear facilities through a wide range of activities: examining the files submitted by Operators of facilities in operation or under construction, supporting inspection teams from the French safety authority, contributing to the process of updating national and international regulations, developing research programs regarding the prevention of accidents...
With ionizing radiation being found in such wide-ranging applications, radiation protection for workers and the public is an essential aspect of IRSN’s activity.
IRSN is responsible for performing radiological monitoring of the environment throughout France, carries out research and analysis to better understand the exposure of workers exposed to radiation, and works to improve the conditions of patient exposure.
Emergency & post-accident situations
In the event of an incident or accident involving sources of ionizing radiation, IRSN provides guidance to public authorities on the technical, public health and medical measures to be taken to protect the population, workers and the environment, while restoring safety at facilities. IRSN's emergency response center can be called in at all times.
Security and non-proliferation
IRSN contributes to national and international efforts to control nuclear and sensitive materials and protect facilities against malicious acts, through the enforcement of treaties on control of nuclear and sensitive materials, and the escort of international and national inspection teams.

Annual Report 2016
The annual report offers a comprehensive panorama of the year’s key events.
2016 saw the reinforcement of the French system for regulating civil nuclear activities. Two major projects were also initiated for the future of IRSN: the reorganization of its division covering health and environment protection, and IRSN 2030, a project that will trace the strategic ambition of the Institute by 2030.

On 16 April 2018, IRSN and the CEA successfully completed a first test simulating an accident situation in the Cabri reactor at Cadarache as part of an experimental programme. This experiment was conducted on a new pressurised water loop and is the first step in the CIP international research programme to improve reactor safety.
The epidemiological study EPICE provides well-documented answers regarding non-cancerous radiation-induced effects. This study does not observe an association between cardiac arrhythmia and caesium-137 deposition levels on children living in the Bryansk region exposed to Chenobyl fallout.
IRSN publishes the lessons learned from its analysis of significant events which have occurred in 2015 and 2016 at 85 civil basic nuclear installations (INBs) other than nuclear power plants (NPPs) in operation. This report is marked by a stable number of events and by the preponderance of events that originate from human and organizational factors.
RNM, the French national network for environmental radioactivity measurements, centralizes all the monitoring data on environmental radioactivity in France and ensures their quality and harmonization through an accreditation procedure. Its website is now available in English.
In this new issue of Aktis in English, you will find a focus on modeling tritium transfer in the environment to assess its impact.
Fields of activity
IRSN contributes to the safety of existing and future nuclear facilities, and to radiological monitoring of the national territory and workers exposed to ionizing radiations.
IRSN offers its expertise and services in nuclear safety, human radiation protection and protection of the environment to authorities and industrials across the world.
IRSN is also an active partner in :
IRSN’s research focuses not only on acquiring new scientific knowledge, but also on developing technical tools required to control risks and help expand the Institute's expertise capabilities. These programs are adapted to take into account normative, regulatory, technological, industrial and social issues.
