Better estimating the risk of coastal flooding for nuclear power plants

​A joint research team from France and Quebec is developing a more accurate methodology to prevent human and environmental disasters.


IRSN publishes the englisg version of the new edition of its reference book entitled: "Elements of nuclear safety - Pressurized water reactors"

​The book "Elements of Nuclear Safety - Pressurized Water Reactors" brings together, in its 40 chapters, elements of technical culture relating to the control of nuclear risks of pressurized water reactors and constitutes an educational reference book.


Fukushima: Predicting the dispersion and impact of radionuclides. The AMORAD project delivers its conclusions

T​he Fukushima Daiichi accident in March 2011 dispersed a significant amount of radioactive elements into the atmosphere and the Pacific Ocean. What are the consequences of these releases on the terrestrial and marine environment? This question has guided the AMORAD project during its 9 years of research. This project is now delivering its conclusions.


Medical radiation protection: The European MEDIRAD project delivers its recommendations

​aunched in 2017, the research of the MEDIRAD (Implication of MEDedIcal low-dose RADiation exposure) project has resulted in a series of recommendations. They aim to ensure a better quality of life for patients and better protection for healthcare professionals when using ionizing radiation in the medical field for diagnostic and therapeutic purposes.


47 thesis proposals for 2021!

​This year, IRSN is proposing 47 topics in all scientific disciplines, for PhD theses that will start in October 2021. A full description of each thesis project is available online, in the "Theses" section of the IRSN website, enabling applications to be filed directly with the thesis supervisor.


Post-doctorate proposal at the Microirradiation, Neutron Metrology and Dosimetry Laboratory (LMDN)

The LMDN is recruiting for an 18-month post-doctoral contract, starting in January 2021 at Cadarache, on the subject "Development of a microfluidic system for the micro-irradiation of non-adherent cells and pluricellular organisms. Application to the study of ionizing radiation effects on Parkinson's disease".


Modelling the behaviour of overhead crane bridges during an earthquake: call for participation in an international benchmark

​From June 2020, IRSN and EDF organise an international benchmark, under the aegis of the OECD/NEA, to compare the models used to simulate the behaviour of overhead crane bridges during an earthquake. The failure of this equipment widely used in the nuclear industry can, for certain scenarios, contribute significantly to the probability of reactor core meltdown. Assessing their behaviour in the event of an earthquake is therefore a major safety issue. This assessment involves modelling the mechanical behaviour of these devices during an earthquake, which represents a scientific challenge due to the importance of contact dissipative phenomena.


IRSN and the University of Tokyo join forces to study aerosol dispersion

​In November 2019, IRSN and the University of Tokyo signed a Memorandum of Understanding seeking to further our knowledge of the interactions that take place between droplets and solid aerosols. This has already involved around ten tests carried out at IRSN's TOSQAN facility, the most recent of which was completed on February 14, 2020.


Research on co-activity: initial findings and four-year extension

​The IRSN has just published its initial findings following research carried out under the COSEA program, focusing on co-activity during the complex project to extend line 14 of the Paris metro. A promising first stage has led the IRSN and its partners to extend the project to 2023.


European Radiation Dosimetry Group (EURADOS) network convened for its annual meeting in Florence, Italy

The EURADOS network comprises over 70 European institutions and 630 members who work together to help harmonize practices and support technical and scientific research in the field of ionizing radiation dosimetry at both European and global level.


European IVMR research program on corium retention delivers its final results

Partners involved in the IVMR (In-Vessel Melt Retention) program, led by the IRSN, present their findings at a seminar held at the Juan les Pins conference center from January 21 to 23, 2020. ​


54 thesis proposals for 2020!

​This year, IRSN is proposing 54 topics in all scientific disciplines, for PhD theses that will start in October 2020. A full description of each thesis project is available online, in the "Theses" section of the IRSN website, enabling applications to be filed directly with the thesis supervisor.
