摘　　要：在堆芯熔化情况下，ＵＯ２燃料与锆合金包壳之间的反应将导致一系列的新相生成及氧自ＵＯ２燃料向包壳合金的扩散，进而对包壳的水侧氧化动力学过程中的相间界面推移产生重要影响。本文推导建立了在这种条件下计算锆合金包壳水侧氧化动力学的方法。Various phases formed and the diffusion of Oxygen resulted from the chemical reaction of UO2-Zircaloy in in-pile meltdown case have an important influence on the oxidation of Zircaloy resulted from the reaction of cladding-steam. In this paper the formula for calculating the kinetics of cladding-steam reaction under the case of UO2-Zircaloy reaction was presented.
