A liquid Lead-Bismuth Eutectic (LBE) spallation target has been developed for the subcritical multiplier (SCM) station of the Accelerator-Driven Test Facility (ADTF). Target design objectives and constraints were defined and utilized to satisfy the engineering requirements and to minimize the design development time and cost. Physics, heat transfer, hydraulics, structural, radiological and safety analyses were iterated to arrive at the final design concept. The optimization of the thermal hydraulic characteristics of the target concept through the parametric evaluation of multiple design alternatives using Computational Fluid Dynamics (CFD) to predict fluid dynamics and heat transfer behaviors is described in this paper.
