Self-cooled liquid metal breeding blankets are in principle the simplest type of blankets that can be used in fusion reactors. Two critical issues in such blankets are strong magnetohydrodynamic (MHD) effects and the heat extraction capability from the first wall using liquid metals. In this work we estimate from first principles the MHD friction factors and Nusselt numbers applicable to convective cooling of the first wall using liquid metals. This is followed by a parametric, thermal-hydraulic study of the first wall cooling capability in self-cooled blankets with emphasis on coolant channel dimensions, dynamic pressure drop and heat removal rate to pumping power ratio.
