Simulation of the dissolution kinetics of Zro2 by molten Zircaloy-4 between 2000 and 2400 ° C

Abstract A numerical simulation of the dissolution kinetics of ZrO 2 by molten Zircaloy-4 in the temperature range of 2000–2400 ° C was made taking into account experimental laboratory determinations. The LISI code, already developed for the dissolution of UO 2 by molten Zircaloy-4, was applied with some modifications in the case under consideration. The proposed changes allowed an acceptable agreement to be obtained between numerical and experimental results.
