The dual-cooled waste transmutation (DWT) blanket has been proposed to transmute long-lived nuclear waste,to breed nuclear fuels such as tritium and plutonium and to generate energy.The special magnetohydrodynamics (MHD) problems of liquid metal LiPb flow in the DWT blanket are caused in the "banana shape" blanket module.The MHD effects of liquid metal LiPb fluid have been simulated and analyzed by using computation fluid dynamics (CFD) code added MHD user subroutine. The velocity profile and pressure distribution of LiPb flow in bend channels have been presented.The effect of wall conductance ratio of wall on flow velocity is analyzed.These results may be used as a reference for thermal -hydraulics and structure design of the DWT blanket.
