Preliminary electromagnetic, thermal and structural finite element analysis of FAST load assembly

FAST (Fusion Advanced Studies Torus) is a proposal for a satellite facility of ITER. This current article deals with the development of a complete sequence of finite element models to analyze and verify if the initial geometry chosen for the main structural components of the tokamak called FAST is satisfactory. The first step is concerned with the evaluation of the magnetic field and the following forces produced by the current flowing in the central solenoid, in the outer poloidal coils and in the toroidal ones; the second step is the estimate of the resulting temperatures in the current-carrying conductors; and the third one is the assessment of the state of stress coming from the loads reminded above. The current loads that have been used come from a different analysis that takes account of the equilibrium with plasma. The code employed has been Ansys Rel. 12.
