| 内容記述 | Overview of plasma facing components (PFCs) in JT-60SA is introduced, including upper divertor, lower divertor, inboard first wall and outboard first wall. These PFCs are upgraded in 4 stages along plasma experiment of JT-60SA; In the Stage1, only partial inboard first wall and upper divertor are installed with graphite tiles and inertial cooling. In the Stage 2, remaining PFCs including outboard first wall and lower divertor are installed, and the inboard surface is fully covered. In the Stage 3, vertical targets of lower divertor are replaced by CFC monoblock targets with water cooling. In the Stage 4, whole carbon wall is replaced by tungsten wall, and remote handling for lower divertor is introduced. Three R&D on major issues concerning PFCs are presented. Mock-ups of CFC monoblock target were fabricated and it showed good heat removal of the expected maximum heat load of 15 MW/m2 without degradation of performance. Samples tungsten coating on CFC were fabricated and they showed no severe damage by surface temperature up to 2000 C. Laser welded samples showed good appearance and no defect was found by RT. | |||||
