摘　　要：本文根据堆芯倒料的基本关系式,提出了不同燃耗深度燃料元件堆芯的最佳倒料原理和由这一原理得出的几点结论。给出了不同倒料方式的计算公式,编制了计算程序并对高通量工程试验堆(HFETR)典型堆芯装载的不同倒料方式作了计算。应用文中提出的堆芯燃料元件耗用指标,分析了HFETR十年来24炉运行的堆芯燃料管理工作。结果表明,应用最佳倒料原理可大量节省燃料元件。本文还讨论了HFETR堆芯燃料管理研究的方向。Based on basic formula for core refueling, this paper suggests the optimal refueling principle for cores with fuel assemblies of different burnup. Some conclusions derived from this principle are given. Calculation formula for different refueling scheme and computation progamme are derived and used for the HFETR typical core loading with different refueling scheme. With the suggested core fuel consuming index, core fuel managements of 24 cycles in 10 years operation of HFETR were analyzed. Results show that the application of optimal refueling principle can greatly save the fuel consuming. Direction of HFETR core fuel management research was also dicussed.
