The radial plates (RP), which is used in Toroidal field (TF) coil in ITER, are quite large, such as 13 m tall and 9 m wide, but thin, such as 10 cm thick. Even though they are very large structures, high manufacturing tolerances required. The authors therefore performed trial manufacture of full-scale RP. As a result of trials, it was highly accurate RP manufacturing method was able to be proven. In addition, actual RP production is advanced based on full-scale RP manufacture result. In this announcement, it is a report about the progress of a result and the actual RP production of the full-scale trial manufacture.
