ENGINEERING DESIGN AND PERFORMANCES OF THE IGNITOR FIRST WALL

Extensive work was carried out to define the working conditions and the reference design of the first wall for the IGNITOR machine: graphite covered modular elements attached to the vacuum vessel by a locking key for remote handling are proposed. The work includes a transient thermostructural analysis of the graphite tiles to evaluate temperatures and thermal stresses in normal and fault conditions. A full scale prototype of the element was manufactured.
