Description
The projects of neutron sources based on nuclear fusion is becoming an important argument for the strategic positioning of the road-map of fusion realization worldwide. In this context, the paper presents a NEW innovative conceptual study of a neutron source based on a spherical tokamak(ST). The plasma scenario chosen for the ST is non-thermal fusion ( hot ion mode) , extensively used on machines like JET and TFTR Deuterium-Tritium (DT) experiments, which seems suited for low fusion gain reactors. As demonstrated on experiments, this scenario is a robust tool for neutron production. Starting from a new scaling law of energy confinement tested approximately on ST40 spherical tokamak, the parameters of a 15MW ST DT Fusion reactor (ST180) are derived and a preliminary radial build of the machine is determined.
