Enhancing Nuclear Safety
Chernobyl, 35 years later
35 years after the Chernobyl nuclear accident, we review the situation with four information notes.
Fukushima, ten years later: our special issue
This accident, like those before it, has led IRSN to conduct extensive research and take action to enhance safety at nuclear facilities and radiological protection of people and the environment. We must do everything within our power to prevent accidents, even though there are no guarantees that they will not occur. In this special edition of Repères, we review the situation.

Annual report 2019
The annual report offers a comprehensive panorama of the year’s key events.
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.
