环形燃料可显著提高压水堆堆芯功率密度，对实现反应堆小型化设计和经济性提高具有重要意义。本研究为获得环形燃料栅元的有效温度计算方法，以西屋公司设计的环形燃料栅元为计算对象，开发了环形燃料单通道热工水力分析程序THCAFS（Thermal-Hydraulic Code of Annular Fuel with Single channel），建立了环形燃料栅元的有效温度的计算模型。基于THCAFS分析了西屋公司四环路压水堆所设计的环形燃料栅元的热工水力性能，并与VIPRE-01、TAFIX和NACAF的计算结果进行Code-to-Code对比验证。同时，利用蒙特卡罗程序SERPENT模拟燃料棒中径向功率分布和燃耗过程，通过自主开发程序THCAFS模拟燃料棒中的...

[Background] The annular fuel can increase the power density of the reactor due to its double-sided cooling, which is of great significance to the miniaturization and long-life operation of the pressurized water reactor. [Purpose] This study aims at the calculation method of effective temperature of annular fuel cell by developing the thermal-hydraulic analysis code named THCAFS (Thermal-Hydraulic Code of Annular Fuel with Single channel) for annular fuel, and establishing a calculation model for the effective temperature of the annular fuel ce...
