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.
Fukushima Daiichi in 2016
An in-depth look at the state of the facilities of the Fukushima Daiichi nuclear power plant five years after the accident:
the struggle to regain control of the plant and manage radioactive releases, the decontamination efforts, the significant health and social consequences of the accident, the progress of research to prevent nuclear accident.
Annual Report 2015
The annual report offers a comprehensive panorama of the year’s key eventsThe
year 2015 marks a legislative and regulatory turning point for IRSN and
France. The Act on energy
transition for green growth not only introduces proposals concerning the energy mix and
ways of saving energy that concern society as a whole, but also
consolidates the national nuclear safety and radiation protection system.
The webdocumentary "Kotoba: Dialogues in Fukushima" keeps alive the experience for the rehabilitation of living conditions in the areas contaminated by the Fukushima accident.
Giving voice to the Japanese, it tells the story of 4 years of dialogue between radiation protection experts and a community of individuals living in Fukushima Prefecture who want above all to regain full control over their lives.
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.

In this new issue of Aktis in English, you will find a focus on geochemical investigations downstream from former mines.
IRSN publishes its report on the safety of transport of radioactive materials for civilian use in France for the years 2014 and 2015. It is based on an overall review of the significant events that occurred during this period during transport operations in France by road, railway, inland waterway, sea and air of 980 000 parcels loaded with radioactive substances.
Iodine-131, a radionuclide of anthropogenic origin, has recently been detected in tiny amounts in the ground-level atmosphere in Europe. The preliminary report states it was first found during week 2 of January 2017 in northern Norway. Iodine-131 was also detected in Finland, Poland, Czech Republic, Germany, France and Spain, until the end of January. The levels measured raise no health concerns.
On 30 November 2016, IRSN submitted to ASN its assessment of the risks of fracture in steam generators (SG’s) with abnormally high levels of carbon in the steel that makes up their channel head. The local carbon levels measured in these channel heads are in the region of 0.4 % compared to the maximum expected value of 0.22 %. This anomaly meant that a re-examination of the risks of fracture of those steam generators was required since the mechanical properties of the steel have been altered.
In this new issue of Aktis in English, you will find a focus on EPR, a rapid dosimetry technique in development.
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.
