To improve the safety margin of TEF-T lead-bismuth spallation target, it is necessary to eliminate the stagnant flow region in liquid lead-bismuth and to reduce the stress level on the target vessel. For this purpose, the target design has been performed by applying the CFD analyses and the structural analyses. Results showed that the safety margin of target can be improved effectively by the modification of target inner structure.
