摘　　要：在新燃料设计中,为更好保证燃料棒完整性,提出燃料棒设计准则中影响燃料棒内压和燃料温度的关键参数和分析模型。以田湾核电站5、6号机组长燃料循环堆芯燃料管理为背景,采用自主研发的燃料性能分析程序FUPAC,模拟稳态和Ⅱ类瞬态工况下燃料棒热-力学行为,分析模型及制造参数对设计准则验证过程的影响。完善了棒状燃料元件内压及温度设计验证过程的评价分析方法。In the design of new fuels,in order to ensure integrity of the fuel rod better,we propose the key parameters and analysis models that affect the internal pressure and fuel temperature of the fuel rod in the design criteria of fuel rods.Based on the background of long fuel cycle core fuel management for units 5 and 6 of Tianwan Nuclear Power Plant,the thermal-mechanical behavior of fuel rods under steady-state and Class II transient conditions was simulated by using FUPAC-a fuel performance analysis program developed independently by our institute.The influence of the model and manufacturing parameters on the verification process of design criteria was analyzed.The evaluation and analysis method for the internal pressure of the rod-shaped fuel elements and the verification process for temperature design were improved.
