Abstract :
A Chinese Dual-Functional Lithium Lead (DFLL) Electromagnetic Test Blanket Module (EM-TBM) is proposed for testing in ITER from the first day of operation for the main test objectives of the electromagnetic performances and MHD effects. The insulating coating has been designated in LiPb flow channels to reduce magnetohydrodynamic (MHD) effect. The MHD pressure drop is theoretically calculated and the influences of the coating electrical resistance and the crack fraction through the coating layer on MHD pressure drop are analyzed. The insulating performance requirements for the coating material are proposed for the EM-TBM based on above analyses. And some R&D issues about coating material and fabrication technology also have been presented in the end.
