ITER-FEAT vacuum vessel and blanket design features and implications for the R&D programme

摘要

A configuration in which the vacuum vessel(VV) fits tightly to the plasma aids the passive plasma vertical stability, and ferromagnetic material in the VV reduces toroidal field ripple. The blanket modules are supported directly by the VV. A full scale VV sector model has provided critical information related to fabrication technology and for testing the magnitude of welding distortions and achievable tolerances.
