In this paper, steady-state Eulerian thermal analysis of welds using moving coordinates is shown. This analysis has been reported as much more computationally efficient method than conventional transient Lagrangian method in which moving heat source actually moves in a computational domain. To show convenience and availability of the Eulerian method, we adopt a computational fluid dynamics code, applied the double ellipsoidal power density distribution model proposed by Goldak et al.(1984), considered temperature dependency of thermal properties, and analyzed a groove weld of a core shroud in a boiling water reactor (BWR). Comparison of the analyzed temperature histories to the measured results shows that the numerical results reproduce the measured results well.
