Despite the sanitary and travels restrictions, 220 participants from 20 countries attended this European conference for the nuclear and radioprotection community. The symposium "After the Fukushima Daiichi accident: adapting to the unexpected" was organized by IRSN following the EUROSAFE Forum.

The mechanical interaction between the nuclear fuel pellets and the cladding tubes (PCMI) is very important for safety studies as this phenomenon could lead to fuel failure and release of radioactivity. During a  power increase in a nuclear power plant the fuel pellets interact with the cladding due to its thermal expansion. Similarly, it is important to investigate the long-term behaviour of irradiated claddings exposed to corrosion and hydrogen uptake in normal operation and in an interim dry storage facility.

The Government of Finland granted Finland’s first nuclear decommissioning licence to VTT Technical Research Centre of Finland Ltd for decommissioning the FiR 1 TRIGA Mark II research reactor. The spent fuel was shipped to the U.S. Geological Survey, which will use the fuel in its own research reactor.

The Deputy Director General of the Agency and Head of the Department of Nuclear Safety and Security and the Director General of IRSN signed an agreement appointing the Institute as the IAEA’s Capacity Building Centre (CBC) in the field of medical management of radiological and nuclear emergencies.

Low power modular reactors, known as Small Modular Reactors (SMR), have generated growing interest in the world for several years now, and particularly in France. The Institute has just published an information note on this technology, covering safety issues.

On September 29, Director General Jean-Christophe Niel inaugurated three IRSN research facilities located in the Cadarache center in southeastern France. They are a testament to the Institute’s ability to design and build innovative experimental devices, essential for carrying out research in support of its safety expertise.

IRSN will coordinate a reply to EURATOM’s 2021-2022 call for applications recently published by the European Commission, regarding the creation of a partnership for radiation protection research.

Researchers worldwide are working on small modular reactors (SMR) and microreactors (very small modular reactor, vSMR). Many of these new reactor concepts are being developed for specific applications and have special core geometries. In order to be able to simulate the neutron-physical behaviour of these cores, GRS is developing the simulation code FENNECS (Finite ElemeNt NEutroniCS).

The jubilee 30th NENE2021 conference was attended by record 236 participants from 22 countries. Varied conference program was accompanied by the ENEN & OECD-NEA Workshop regarding nuclear education and training and the ENEN Ph.D. Event competition.

The National Radiation Protection Institute - SÚRO v.v.i. - became the youngest member of ETSON from January 1, 2021. It replaced the Research Centre Řež (CV Rez), which had been the TSO in the Czech Republic since 2011.
