Abstract

DEMOnstration fusion reactor (DEMO) represents the second step in the EU fusion roadmap that has the objective to demonstrate the feasibility, from an economic point of view, to produce electric power using fusion reaction. The structural analyses of such a large machine represent a crucial issue for the design assessment. In fact a full detailed 3D model would require a huge mesh. In this work a novel procedure is presented, based on Radial Basis Functions interpolation, that allows to recover the stress state in a generic 3D section with low computational effort and significant time saving. This tool uses a mixed approach that allows to adjust the boundary shape and applies the magnetic loads to the local 3D model. To prove the Stress Recovery Tool (SRT) validity the results, obtained in a portion of the whole structure, have been compared to those of a high fidelity model. Once validated the SRT has been applied to a 2015 reference geometry.
