Enhancing Nuclear Safety
Flamanville EPR reactor
Conclusions of the assessment by IRSN (the French technical support organisation) and the Nuclear Pressure Equipment Department of ASN
(the French nuclear safety authority) of the serviceability of the closure head and lower head of the Flamanville EPR reactor pressure vessel.
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.
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.
IRSN hosts the 4th International Symposium on the System of radiological Protection and the 2nd European Radiation Protection Research Week
From 10 to 12 October 2017, IRSN hosts in Paris (France) the International Commission on Radiological Protection (ICRP) and the European research platforms
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.

Precise measurement of internal contamination from a wound is a major challenge for the nuclear sector when it comes to radiation protection. IRSN has launched an international exercise to improve the procedures used to perform these measurements.
The cooperation agreement will strengthen the cooperation in understanding and computer simulations of processes during severe accidents with melting of the reactor core and understanding potential environmental hazards that may pose potential risk to nuclear facilities and, of course, planning effective defense against them.
The guidelines presented at the final meeting of the European Shamisen project underlines the importance of involving population in the management of an accident and taking into account the economic and social upheavals and the psychological effects, particularly in the context of an emergency evacuation.
The National Institute for Quantum and Radiological Sciences and Technology (QST) carries out research on the cancerous effects of ionizing radiation which are complementary to those carried out by IRN on non-cancerous effects.
From their joint analysis of the files submitted by Areva NP, IRSN and the Nuclear Pressure Equipment Department (DEP) of ASN conclude that if the serviceability of the closure head and lower head of the Flamanville 3 reactor pressure vessel is demonstrated, in-service inspections must be implemented. At this stage, the feasibility of these inspections appears to have been acquired for the lower head. The same is not true for the closure head.
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.
