Rostechnadzor issued operating licenses to FSUE Atomflot for operation of the nuclear-powered icebreaker Siberia that had completed trial trip in the Baltic Sea. The License was issued on the basis of safety analysis review for the icebreaker operation carried out by SEC NRS, the scientific and technical support organization for Rostechnadzor.

The first meeting of the Management Board of the Multinational Design Evaluation Programme (MDEP) was held via videoconference on January 13, 2022.

In accordance with a number of state contracts the Russian Federation constructs several dozens of NPP units abroad and produces nuclear fuel for them. Besides, the Russian Federation implements spent nuclear fuel (SNF) reprocessing services for some of these NPP units.

First prize to an UNIBO-ENEA-IRSN team for safety studies of SMR severe accidents, second prize to a PSI team for the use of the surgical mask as an emergency dosimeter, at the EUROSAFE Forum in Paris-Montrouge.

To reduce SNF cask failure risk in the ISFSF building areas, where SNF cask could be lifted more than 30 cm, special design shock absorbers are installed. The main function of these shock absorbers is to reduce the dynamic loads to a fully loaded SNF cask (weight 77 - 89 t) in case of dropping and prevent or minimise the possibility to lose the tightness of the SNF cask and release of radioactive materials from SNF rod(s). Evaluation of the shock absorbers capability to withstand the dynamic load in case of an accident was performed.

RATEN ICN was designated as IAEA International Centre based on Research Reactors for the “Education and Training” and for “Joint Research and Development (R&D) Projects” fields, joining the Network of other 6 well-known institutes from the USA, France, Belgium, Korea and Russia.

Scientists of Lithuanian Energy Institute have recently collaborated with colleagues from other European TSOs and ETSON partners in research activities – BARCO and ETSON-SAMHYCO-NET benchmarks.

The Advanced Thermo-Hydraulics Experiment for Nuclear Application (ATHENA) facility will be built at Mioveni platform, on the RATEN-ICN research center premises. 

Ph.D. student Noura Elsalamouny (Lithuanian Energy Institute, Laboratory of Nuclear Installation Safety) participated in Summer School 2021 “Modelling, Experimental and Validation” (MeV) organized through the cooperation of multiple stakeholders, i.e. Argonne, Idaho and Oak-Ridge national labs. Noura worked in a team together with other students and presented joint work titled “The at-home micro reactor”. This futuristic idea was investigated in terms of the conceptual goals set, the necessary safety requirements, the design constraints, and the economic benefits of a micro-reactor installed at-home.

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.
