Riassunto
The work deals with the evaluation of the seismic response of the ITER Tokamak machine, to be constructed in Cadarache.
ITER will be an experimental fusion reactor based on the concept of the magnetic confinement, inside which the plasma is contained in a doughnut-shaped vacuum vessel. In particular ITER will be the first occasion to demonstrate licensable fusion safety and environmental potential of the fusion.
The aim of the study consists mainly in the investigation of seismic load and the effects that this unpredictable external event could pose in the tokamak machine components.
To the purpose the Power Spectral Density approach has been adopted to properly determine the Floor Response Spectra.
The model used was implemented by means of ANSYS © code; it was set up by considering appropiate boundary and initial conditions as well as material properties.
The obtained results are critically discussed in terms of stress, displacements and acceleration spectra.
