从反应堆堆芯部分的物理和热工水力实际过程出发，经过简化建立了１０ＭＷ高温气冷堆堆芯的具有分布参数的非线性的动态数学模型，并采用多重网格算法研究了在典型工况下堆芯的动态响应特性。计算结果表明，在额定工况下模型的稳态结果与设计数据相符合，动态结果也符合基本的物理规律。由于缺乏同类反应堆动态数据，动态结果需要进一步校验。
Based on the actual physical and thermal-hydraulic processes of the reactor core, a nonlinear dynamic mathematical model with distributed parameters of a 10MW high-temperature gas-cooled reactor core was established. The multi-grid algorithm was used to study the dynamic characteristics of the reactor under typical working conditions Lower core dynamic response characteristics. The calculation results show that the steady-state results of the model are consistent with the design data under rated conditions and the dynamic results are in line with the basic physical laws. Due to the lack of similar reactor dynamic data, the dynamic results need further verification.
