Fabrication of an ITER shielding blanket prototype

A full-scale prototype mockup of the FER shielding blanket composed of the first wall with built-in circular tubes and the shield block has been succe ssfully fabricated Joints of the first wall/the shield block as well as tho se of the DSCu/DSCu, DSCu/SS and SS/SS in the first wall, were simultaneous ly HIP bonded The fabricated prototype mockup fully satisfied the specified design conditions such as dimensional accuracy, pressure resistance, etc. After HIPping, HIPped interfaces were metallographically observed with piec es cut from the edge of the mockup. There were no harmful voids at the bond ed interfaces, and good bondability of simultaneous HIP method was confirme d In addition, engineering data on fabrication including bonding deformatio n were obtained.
