MHD flow and heat transfer have been analyzed for a front poloidal channel in the outboard module of a Dual Coolant Lithium
Lead (DCLL) blanket, with a flow channel insert made of a silicon carbide composite. The US reference DCLL blanket module

as insulator was assessed via numerical simulations based on a 2D model for a fully developed flow and on a 3D model for heat
transport. Parametric studies were performed at = 5500 ( m)-1
and k = 220 W/m K. Parameters resulting in a reasonably
