The first project under the new Fusenet PhD initiative Fusion PhDs for M.S.c. fusion projects !

OVERVIEW

Electromagnetic loads generated during off-normal plasma scenarios are one of the major concerns in the design phase of fusion devices. The induced current, that contributes to the generation of these loads, is very sensitive to the component’s physical properties such as the electrical resistivity. In this context, a tool for the evaluation of equivalent resistivity useful in 2D and 3D electromagnetic FEM analysis is needed. In fact, the focus of this proposal is to simplify the modelling phases of complex components preserving a high degree of detail in the evaluation of the electromagnetic loads. This procedure will integrate with the UNITUS recently developed methodology based on the use of MAXFEA code in combination with ANSYS APDL. This specific coupling tools procedure was applied to study the electromagnetic behavior during a plasma disruption for fusion device such as DTT, DEMO or ST40.
