Abstract
In order to investigate the manufacturing and qualification methods for the first wall (FW) of the International Thermonuclear Experimental Reactor (ITER), we fabricated several mock-ups with various shapes through the hot isostatic pressing (HIP) bonding method for joining the Cu-alloy with Be armor and the Cu-alloy with stainless steel (SS). Non-destructive test (NDT) methods currently being developed for the ITER FW were applied to these mock-ups to find the defects. Ultrasonic test (UT) showed that a probe of 10 MHz and 0.25 inch in diameter could detect defects up to 3 mm in diameter. The eddy current test (ECT) for the SS tube was simulated with a numerical code and showed the feasibility of detecting defects in the SS tube. Thermography was simulated with a numerical code, CFX-10, and preliminary tests were performed. Also, a high heat flux (HHF) test was performed up to 1000 cycles at 5.0 MW/m$^2$ for the Cu/SS mock-up in Japan (JEBIS, JAEA Electron Beam Irradiation Stand), and it is being prepared for the Be/Cu mock-up in Russia.
