Iter

ITER is the experimental reactor whose mission is to demonstrate the scientific and technologic feasibility of nuclear fusion as an energy source. After more than a decade of design and R&D activities carried out by Europe, Japan, United States and Russia in collaboration, the ITER project is now definitive and its construction is started.

Electromagnetic and thermo-mechanical FE analyses for the structural assessment of the Divertor Cassette have been performed following various analysis procedures:

  • neutronic analyses
  • transient heat transfer analysis under the effect of the neutronic heat deposition
  • electro-magnetic analyses
  • static and dynamic elastic analysis under different load conditions: dead weight, Cassette pre-load, thermal strain due to neutronic heat deposition, Electromagnetic (EM) loads

W7X Stellarator Fusion Machine

Global model for the simulation of the structural behavior of the Wendelstein 7-X magnet system within the finite element method (FEM) framework. The magnet is a highly engineered coil architecture, consisting of five identical modules, each spanning a 72° sector.
This integrated modeling approach enables a comprehensive assessment of the system’s mechanical response under operational loads, thermal conditions, and electromagnetic stresses.

By consolidating all module interactions into a unified analytical environment, the model supports a more reliable evaluation of global deformations, critical stress concentrations, and long-term structural integrity.
Such a configuration ensures consistent performance insights across the entire assembly, streamlining both validation processes and decision-making for design optimization and lifecycle management.

Ignitor

IGNITOR is a compact high magnetic field Tokamak machine aimed to produce the ignition of the Nuclear Fusion reactions. IGNITOR is part of a line of research that began with the Alcator machine at MIT in the 1970’s which pioneered the high magnetic field approach to plasma magnetic confinement, and continued with the Alcator C/C-Mod at MIT and the FT/FTU series of experiments. Electromagnetic as well as structural analysis have been performed for the structural assessment of the machine during disruption events. Dynamic elastic-plastic analysis of the IGNITOR vacuum chamber were performed in order to assess the low-cycles fatigue behavior of the structure.
