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.

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.

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.
