The "European School on Nuclear Materials Science" 2020 (ESNMS), co-organised by INSPYRE with the GEMMA, M4F and IL TROVATORE  H2020 projects under the auspices of the Joint Program on Nuclear Materials, took place online from November 9^th to 13^th. 

The school covered the main experimental characterization techniques and multiscale modelling methods used for the study of nuclear materials. It consisted of 17 courses on techniques and methods and 6 case studies on the contribution of materials science to the study of various issues concerning the behaviour of nuclear fuels, as well as metallic and ceramic structural materials of fission and fusion reactors. The ESNMS brought together 45 participants from all over Europe, mostly doctoral students, but also master's students, post-docs and a few permanent researchers, supervised by 18 lecturers from the co-organizing projects. In order to increase student interactions and active participation, participants worked in groups on the case studies and presented the results of their work in front of their fellow students.
