摘要: 本文对高燃耗对乏燃料包壳结构完整性的影响进行了分析。探讨了影响包壳结构完整性的重要温度限值,即燃料包壳温度限值、包壳溶解温度以及韧脆转变温度(DBTT)。给出了分析包壳结构完整性的方法,对拟在干式贮存设施内贮存超过20年的容器性能及贮存后运输时乏燃料组件的结构完整性进行了分析,并给出了相关建议。

关键词: 高燃耗, 乏燃料, 贮存, 运输, 包壳, 结构完整性

Abstract: The integrity of the spent fuel cladding structure with high burn-up was analyzed. Several important temperature limits, such as fuel cladding temperature limits, cladding solution temperatures, and DBTT, which will affect the structural integrity of the cladding, were discussed. The method for analyzing the structural integrity of the cladding was given. On this basis, the performance of the container to be stored in the dry storage facility for more than 20 years and the structural integrity of the spent fuel during transportation after storage were analyzed and relevant recommendations were given.

Key words: high burn-up, spent fuel, storage, transportation, cladding, ductility, structural integrity
