This article is written to honour the scientific achievements of prof. Eugenijus Ušpuras, who passed away in 2019. Therefore, his colleagues summarized retrospectively main research topics like safety studies for Ignalina NPP, research in nuclear fusion and investigations in energy security prof. E. Ušpuras worked with. Since prof. Eugenijus Ušpuras spent his entire scientific career at Lithuanian Energy Institute (LEI) all these three topics are directly related to the development of the nuclear energy topics and research performed in Lithuania during the last decades.
