Abstract
In order to verify the integrity of the first wall (FW) of the International Thermonuclear Experimental Reactor (ITER), the fabricated Cu/SS mock-ups were tested with an e-beam facility, JEBIS (JAEA (Japan Atomic Energy Agency) Electron Beam Irradiation Stand). The Cu/SS mock-ups were joined with CuCrZr as the heat sink material among Cu alloys and 316L austenitic stainless steel (SS316L) as the structural material. Hot isostatic pressing (HIP) was used as a manufacturing method at 1050 °C and 100 MPa for 2 h. The high heat flux (HHF) tests were performed for two Cu/SS mock-ups under different heat flux conditions (5 MW/m 2 and 3.2 MW/m 2) and duration times, which were determined from the preliminary analysis with ANSYS-10. The temperature results from the test showed good agreement with the analysis results, and the fatigue lifetime was evaluated from the strain analysis result.
