​​​The 9 magnitude earthquake on 11 march 2011 caused a huge tsunami coastal flooding. It led to the core melt of three reactors from the Fukushima Daiichi nuclear plant and to the loss of cooling of different spent fuel storage pools. 

​​​​​​​35 years after the Chernobyl nuclear accident which occurred on 26th April 1986 in Ukraine, we outline the last information of the situation.​

Jean-Christophe Niel mandate at the head of IRSN was renewed for five years by the President of the French Republic by a decree of 21 April published in the Official Journal of 22 April 2021.​

​Samuel Peillon from IRSN (France) wins ETSON Award with his team cooperating with CEA and CNRS, for their study of the behavior of tritiated dust in fusion reactors such as ITER or the Cadarache Tokamak. ​

On Thursday, 3rd September 2020, the Director General of IRSN held an exchange with the President of the Federal Office of Radiological Protection (BfS), Inge Paulini, on current issues in radiation protection.

Since the publication of the IRSN information report of June 30, 2020, measurements available abroad have made it possible to model the transport of air masses in Western Europe and to determine a plausible geographic area of the release origin which is located on a territory covering part of the Baltic countries and Western Russia.

Measurements in France from the IRSN’s OPERA monitoring network do not reveal the presence of radionuclides linked to this release.

​​​​Jean-Christophe Niel, Director General of IRSN: “The transition and succession will be well assured with this team, which guarantees continuity and the highest level of excellence. I would like to warmly thank Thierry Charles for the expertise he has shared over the years and I salute his entire career and his unfailing commitment to IRSN and nuclear safety.”

The safety and radiation protection authorities of the Scandinavian countries have reported an increase in atmospheric radioactivity detected by their monitoring stations during June.

To date, available measurements from the IRSN’s OPERA monitoring network show no abnormal increase in the level of atmospheric radioactivity in France.

​Since the publication of our information report of April 24, 2020, it seems that the fire outbreaks are now extinct. The new information report published today by IRSN contains the latest information available and updates the modeling of the trajectories of air masses contaminated by fires.
