Description
The French government has recently launched the SupraFusion Research Program lead by CEA and CNRS with the partnership of multiple other national laboratories and universities. This national program has been granted 50 M€ in order to boost the development of HTS superconductors technology towards large societal applications, using the vector of nuclear fusion as a powerful driver for this research and innovation. In order to achieve this goal the SupraFusion Progam has been built around five technological bricks covering the whole life cycle of the technology. The first brick aims to the large characterization and modelling of REBCO tapes allowing magnet designs and qualification with confidence. The second one targets to the development of high current & high field conductors matching the main constraints and performances needed by the magnets. The third brick will deeply study HTS coils quench protection and propose new technological solutions to ensure magnets safety. The fourth aims to design, manufacture and test in nominal conditions a large-scale demonstrator achieving about 20 T and 100 MJ of stored energy to prove this technology viability for fusion and other large-scale applications. The fifth brick will propose designs for future HTS compact fusion machines towards energy production. Finally, in order to wider spread HTS technology potential into society, this large national program will also launch opens calls to support studies or projects targeting the use of HTS technology in other societal applications that could be MRI, wind generators, motors, high energy physics, etc. This paper will present the French SupraFusion scientific program, its strategic road map and the first main achievements.
