NET VACUUM VESSEL AND BULK SHIELD DESIGN
In order to make the most efficient use of the space available inside the toroidal field coils, the NET bulk shield is integrated into the vacuum vessel. In this way advantage can be taken of the structural properties of the material used to provide the basic shielding for the superconducting coils. The combined structure is toroidally segmented into 16 segments to match the toroidal field coils, with each segment divided into 2 modules for assembly purposes. The main vacuum vessel boundary is formed by the inner skin of the structure, with structural strength against atmospheric and eddy current loads (due to plasma disruptions) being provided by the complete assembly. It also provides an efficient containment for the activated materials in case of accident. This report describes the different analysis (thermohydraulic, electromagnetic and mechanical) carried out for a preliminary design of the vacuum vessel and the bulk shield.
