环形燃料组件是一种经济性和安全性前景极好的新型燃料元件,为了验证环形燃料组件的设计与实际性能,需开展环形燃料先导组件堆内辐照实验。应用堆芯燃料管理程序包CMS(CASMO5、CMSLINK5和SIMULATE5)设计4组环形燃料先导组件导入秦山二期平衡循环堆芯,让其在堆芯辐照3个循环,研究分析环形燃料先导组件的堆芯物理性能以及实心燃料与环形燃料在 The annular fuel assembly is a novel fuel element with excellent economy and safety. In order to verify the design and actual performance of the annular fuel assembly, it is necessary to carry out in-reactor irradiation experiments of the annular fuel pilot assembly. The reactor core fuel management package CMS (CASMO5, CMSLINK5 and SIMULATE5) was used to design four sets of annular fuel pilot components into Qinshan Phase II balance circulation core for 3 cycles of irradiation at the core. The reactor stack Core physical properties as well as solid fuel and ring fuel in
