On 4th of June, 2024, members of EUROfusion gathered in Kaunas, the second-largest city of Lithuania for General Assembly, the quarterly meeting of the decision-making body of European consortium for fusion research, where progress towards realising fusion energy is discussed between the consortium members.

Concrete is the primary material used in waste management, making it essential for the concrete industry to develop more environmentally friendly and effective concrete formulations for handling radioactive and hazardous waste. This need is relevant for all countries around the Baltic Sea and beyond.

On March 19, 2025, the largest and most significant economic forum in the country, "Lithuanian Davos 2025," took place, traditionally gathering leaders from business, politics, and society. During the forum, there were not only standard sessions focusing on economic development, investment potential, accessibility of financing, and real estate market development, but also special sessions dedicated to the development of Lithuania's energy sector, defense industry. This 18th event featured a presentation "The Benefits of Small Nuclear Reactors: Where is the Value for the State?" by Dr. Tadas Kaliatka, the chief research associate at the Nuclear Equipment Safety Laboratory of the Lithuanian Energy Institute.

The Lithuanian Energy Institute contributes to the numerical analysis of activation and fission products in irradiated cladding material of the PWR spent fuel assembly.

Lithuanian Nuclear Energy Association in co-operation with the Lithuanian Academy of Sciences and Lithuanian Energy Institute organized the international conference "New Trends of Nuclear Reactors: Small Modular Reactors. Experience of Leading Countries and Developers” with participation of representatives from 5 ETSON organisations (LEI, JSI, VTT, ENEA, EK-CER).

The DEBORA benchmark is an international programme that aims to find a more unified methodology for testing and validating Computational Multiphase Fluid Dynamics (CMFD) models.

EURAD activities cover high priority common interests of different actors involved in safe radioactive waste management. One of the EURAD work packages, WP2 ACED, is devoted to Assessment of Chemical Evolution of ILW and HLW Disposal Cells.

Lithuanian Energy Institute contributes to the analysis of temperature influence on clay-based material behaviour

During the internship the phenomena of High Burnup Structure (HBS) formation was investigated. Working with locally developed mechanistic fission product release code called MFPR-F researcher participated in the code coupling effort, where MFPR code was integrated into TRANSURANUS fuel performance code.

ICONDE project conducts research into concrete design for hazardous waste management applications.
