ITER vacuum vessel is a double comprising of inner and outer shells. Space betw is filled up with ITER vacuum vessel In-Wall S to, (i) provide neutron shielding to toroidal mag and (ii) reduce toroidal magnetic field ripple. T 8960 IWS blocks of different sizes, shapes distributed over nine vessel sectors and corre field joints. Manufacturing of IWS requires va like water jet cutting, precision CNC machining tight tolerances, accurate dimension measu welding, full penetration welding, Non Destruct Various IWS mock ups are manufactured to validate manufacturing and inspection pro sufficient experience gained from manufacturin mock ups, final manufacturing of IWS has s Avasarala Technologies Limited, India. This p important features of IWS design, results manufacturing, optimization of manufacturing processes, assembly and progress of manufacturing.
