FusEUrope is a multidisciplinary project onthe history of European techno-scientific cooperation in nuclear fusion energy research and its interplay with the process of European political integration from the creation of EURATOM in 1957 to the establishment of ITER in 2007. Funded by the Italian PRIN PNRR 2022 program, FusEUrope combines historical, epistemological, and public opinion analyses to provide new insights into the role of fusion research in Europe’s scientific and political landscape.
