Abstract: The next step of the nuclear fusion roadmap is to design pilot plans, the last step before the construction of a nuclear fusion power plant.
Nevertheless, several technical gaps and unknows remains to be resolved linked to the operation of devices with burning plasmas, characterized by a significant population of highly energetic alpha particles.
Examples of such uncertainties affect the power exhaust, plasma-wall interaction, Tritium cycles and breeding as well as the plasma stability. In particular, this presentation is dedicated to discussing the stability of burning plasmas. In that respect, recent experiments in the past Deuterium-Tritium campaign at the Joint European Torus identified the important role of the alpha particle in the stability of the plasma as well as the strong interaction between different populations of energetic particles.
The presentation will provide an overview of different research topics oriented to reactor relevant studies performed by the FAR3d international team.
