Abstract

The design of FAST (Fusion Advanced Studies Torus), the Italian proposal of a Satellite Facility to ITER, is currently under review in order to verify the feasibility of a superconducting version of its magnet system. In a previous study, the 1D analysis of the thermal-hydraulics of the TF cable in conduit conductors (CICCs) have been investigated with respect to one of the most critical operating scenarios (the H-mode reference scenario). In that case the heat coming from the casing to the winding pack due to the nuclear heat from the plasma has not been modeled, nonetheless, based on the experience on other superconducting tokamak machines, the necessity for a proper shield and case cooling system has been recognized. In the present paper the effect of the heat coming from the casing is quantified through a 2D analysis of the TF cross section. The contribution of the casing is further employed as an input for a successive 1D thermal-hydraulic analysis of the CICCs.
