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, 2 years later
Two years after the accident at the Fukushima Daiichi nuclear power plant in Japan, IRSN publishes a new video looking back at the events that led to the meltdown of three reactors.
It explains in particular the difficulties encountered by the operators, TEPCO and the Japanese government in the managiement of the crisis.
Fukushima, 2 years later
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 and 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.

The Norwegian Radiation Protection Authority (NRPA) and the IRSN organized an international conference co-sponsored by WHO by on the prevention of radon risk in homes, on Thursday 11 & Friday, April 12 in Paris.
On this occasion, the speakers from eight countries (United Kingdom, Ireland, Finland, Canada, Switzerland, Germany, Norway and France) presented their actions to reduce exposure to radon in the home.
IRSN and the Atomic Energy of Canada Limited (AECL) have just signed a seven-year cooperation agreement in the area of radioecology and environmental radiation protection. The agreement identifies several areas of mutual scientific interest that will be pooled so that the two partners can take advantage of a joint technical platform and expanded skill sets.
IRSN publishes a new report about transport events involving radioactive materials that occurred in France from 1999 to 2011. For each of the 1 304 events recorded, many parameters have been collected and analysed from information listed in the declarations and reports of events sent by users (type of event, purpose, package design, INES level, etc.).
Two years after the accident at the Fukushima Daiichi nuclear power plant in Japan, IRSN publishes a new video looking back at the events that led to the meltdown of three reactors. It explains in particular the difficulties encountered by the operators, TEPCO and the Japanese government in the managiement of the crisis.
IRSN and GRS are jointly developing the ASTEC software system dedicated to nuclear meltdowns in the different types of reactors currently in operation. A late-January meeting of the ASTEC Users Club in Aix-en-Provence in southeastern France bolstered its position as an international reference and consolidated its scope of applications, which has progressively been extended to include most types of reactors, existing and future.
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.
