Description

This paper is focused on the computation of EM loads induced by plasma current disruptions on the Diagnostics positioned inside the Equatorial Port Plugs, and more explicitly, on the creation of a detailed set of tools (Finite Element ‘FE’ models and routines) which allow the automatic characterization of the EM phenomena (DINA) as well as they provide versatility for the adding/removing of the different internal diagnostics. In this design phase of ITER, are many diagnostics whose level of maturity begins to be sufficiently elaborated to require a detailed study of the volumetric distribution of EM loads. For this specific aim, is desired a proper characterization of the electrical connections together with a correct definition of materials and geometries. The main goal of this investigation is the development of a ‘Generic Tool’ that can be used, for all internal systems, during the phases of design and analysis thanks its ability to adapt to changes in the design. In addition, not only components inside the DSMs need to be covered by EM analysis, exist some safety important components ‘SIC’ bolted or welded to the Port Plug Flange which needs to be assessed, therefore, in further design stages, this tool will be improved to cover in more accurate way all these systems.
