Abstract

On JFT-2M, to investigate whether low-activation ferritic steel (F82H) can be used as a structural material of the demonstration reactor, the Advanced Material Tokamak EXperiment (AMTEX) is being carried out step by step. The AMTEX program consists of three stages. In the 1st stage, the low-activation ferritic steel plates (FPs) were inserted between the vacuum vessel (VV) and the toroidal field coils (TFCs) to reduce the toroidal field ripple. In the 2nd stage, the pre-testing of compatibility with plasma was carried out by partially installing the FPs in the inside of VV. In the 3rd (final) stage, the testing of compatibility with plasma will be carried out by a full covering of the FPs on the inside of VV.
