Study on Corrosion and Hydriding Performance and Model of Specifically Fuel Rod Cladding
-
摘要: 锆合金包壳的腐蚀和吸氢性能是影响燃料棒堆内性能的重要因素。本文在锆合金包壳均匀腐蚀吸氢基本机理和现有模型的基础上,结合某特定燃料棒包壳材料的具体情况和使用特点,建立了包壳材料的均匀腐蚀和吸氢模型,并根据现有辐照数据对所建立的模型进行了验证。Abstract: The corrosion and hydriding of zircaloy cladding are important factors for the characteristics of fuel rods.In this paper,the corrosion model and hydriding model of the fuel cladding used in a specifically reactor have been developed based on studying the existing models and considering the characteristics of the specifically fuel rod,and the new models have been validated using available irradiation data.
