摘　　要：鉴于现有软件均缺乏CF3燃料组件N36锆合金包壳分析能力,开展了燃料棒性能分析程序FUPAC V2.0的研发工作。基于N36锆合金的堆外试验数据和N36锆合金包壳燃料棒池边检查数据,研究了N36锆合金的物理性能、腐蚀行为和辐照生长行为,初步建立了N36锆合金包壳相应模型。在现有自主化软件FUPAC V1.1的基础上,耦合入N36锆合金包壳分析模块,形成FUPAC V2.0,并进行了初步验证。验证结果表明:N36锆合金辐照生长模型和腐蚀模型与目前试验结果符合较好,FUPAC V2.0已实现计算N36锆合金包壳燃料棒性能的功能。The fuel performance analysis code FUPAC V2.0 was developed for the lack of capability of fuel performance analysis on N36 zirconium alloy cladding in CF3 fuel assembly.Physical properties,corrosion behaviors and irradiation growth of N36 zirconium alloy were studied and preliminarily modeled based on out-pile and poolside inspection data.Furthermore,FUPAC V1.1 was updated to FUPAC V2.0 by coupled with N36 zirconium alloy cladding analysis modules.Validation results show that N36 zirconium alloy models are in good agreement with experimental data and the capability of analyzing N36 zirconium alloy cladding fuel rod performance by FUPAC V2.0 is realized.
