选取石墨球与燃料球均匀混合作为１０ＭＷ高温气冷堆（ＨＴＲ－１０）的初始装料方案，利用高温堆物理模拟程序ＶＳＯＰ及二维ＳＮ程序，分析计算了初始装料时ＨＴＲ－１０堆芯进水反应性效应、控制棒及第二停堆系统反应性当量，研究了初装堆向平衡态过渡过程中的临界性、单球最大功率、最大比燃耗等变化情况。结果表明：ＨＴＲ－１０初装堆的进水反应性效应比平衡态小；控制棒及第二停堆系统反应性当量比平衡态的大。但是，初装堆冷态下反应性控制系统当量裕量比平衡态小；过渡过程中有效增殖因数在很小范围内变化，燃料最大比燃耗不超过１００ＧＷｄ／ｔ。
The graphite balls and fuel balls were uniformly mixed as the initial charging scheme for the HTR-10 10MW HTR-10 reactor. The high-temperature reactor physical simulation program VSOP and the two-dimensional SN program were used to analyze the HTR- Water reactivity effect, control rod and the second reactor system reactive equivalence, the criticality of the first reactor during the transition to the equilibrium state, the maximum power of a single ball, the maximum specific fuel consumption and other changes. The results show that the initial reactivity of HTR-10 reactor is lower than the equilibrium state and that of the control rod and the second reactor system is larger than the equilibrium state. However, the equivalence margin of the reactivity control system in the initial reactor is lower than that in the equilibrium state. The effective growth factor in the transition process changes within a small range, and the maximum specific fuel burnup does not exceed 100GWd / t.
