![عکس صفحه اول مقاله: Fabrication and high heat flux test with the first wall mockups for developing the KO TBM Fabrication and high heat flux test with the first wall mockups for developing the KO TBM](/preview/png/271829.png)
Korea has proposed and designed a helium cooled molten lithium (HCML) test blanket module (TBM) to be tested in the ITER, in which Ferrite Martensite steel (FMS) and Be were used as the structural and armor materials of the first wall (FW), respectively. In order to develop the fabrication technology for a TBM structure, joining of FMS to FMS was developed and proved through the high heat flux (HHF) test in the previous study. Then, joining of Be to FMS has been developed with several interlayers and mockups were fabricated with hot isostatic pressing (HIP) in the present study. Mockups with Be joined to the FMS were successfully fabricated with a HIP (580 °C, 100 MPa, 2 h) by trying the different interlayers (1 μm-Ti/0.5 μm-Cr/5 μm-Cu and 1 μm-Cr/5 μm-Cu). The HHF tests with a Korea Heat Load Test (KoHLT-1 facility) were performed with 1000 cycles under 0.5 MW/m2 heat flux. The test conditions were determined with ANSYS-11 and the test results were compared with the preliminary analysis ones. During the test, there was no sudden increase of temperature but UT and DT results after the test showed a delamination in the case of using Ti/Cr/Cu interlayer. But the mockup with the Cr/Cu interlayer showed a sound joining even after HHF test. Moreover, large mockups considering the TBM FW were designed and started their fabrication for developing the fabrication methods and procedure.
