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.

In the framework of the Euratom Research and Training Programme, HARMONISE (a project expected to start in mid-2022) will study relevant research and cooperation activities in standardization and nuclear safety considering also the lessons learnt from the stress tests performed in the EU. The project is coordinated by LEI and involves nine ETSON members along with partners representing research organisations, regulators and industry.

Scientists of Lithuanian Energy Institute have been developing an open-source turbulent combustion solver flameFoam, based on OpenFOAM toolkit. Code to code analysis and comparisons with experiments showed that flameFoam mostly corresponds to the state-of-the-art currently achieved in the field.

For the examination of plasma and impurity transport in the DT experimental campaign, energy balance, dependency on discharge, and the time evolution of radiation loss profiles are provided by LEI scientists. Indeed, the record braking pulse  is also being analyzed here at LEI.
