Liquid metal cooling system piping optimization within magnetic field of a Tokamak fusion reactor

A gallium cooled divertor target design has been considered for the ARIES project of a commercial fusion reactor with a double-null divertor. The pressure drops within the reactor magnetic field have been calculated with the use of a quasi-one-dimensional mathematical model of MHD flow. The total pressure drop for a line was found as the sum of the pressure loss in each of the duct pieces wherein the uniform MHD flow approximation was used, and the local pressure drops in various bends and joints. The basic simplicity of the model provides a unique feasibility of the real design analysis taking into account the complicated pipelines geometry with all its bends and cross-section variations in the nonuniform magnetic field of the tokamak. This circumstance is of special value for the in-reactor part of the liquid metal loop optimization in terms of gallium inventory which is quite important due to its high cost.
