From Design to Procurement of Tokamak Mechanical Structures

Nuclear fusion facilities, as tokamaks, are very complex devices, due to the harsh environmental conditions required to maintain the plasma advance confinement scenarios and the deuterium-tritium fusion reaction (huge temperatures, nuclear radiation, extreme electromagnetic loads). Therefore, several specific concerns shall be considered during the design process of a tokamak, and appropriate solutions shall be designed and provided. These concerns are treated in this paper and some of their possible solutions are explained. This is done following the flow of good practice design process, focusing on each stage from the material selection to the component procurement.
