Analysis has been performed to evaluate the possibility of using liquid lithium as a coolant for the limiter. A global analysis was carried out to determine limiter's shape and configuration, and then detailed MHD, heat transfer, and structural analysis, were performed to determine limiting coolant velocities, operating pressures, Nusselt number, and allowable heat fluxes. For one of the most suitable choices of materials i.e. vanadium structure, lithium coolant, and Be coating (10 mm), the limiting heat flux has been found to be 2.5 MW/m/sup 2/. For High, Z coating of tungsten the limiting heat flux has been found to be 5.7 MW/m/sup 2/. In both cases the operating pressure was maintained at 10 MPa.
