中文摘要	低温核供热堆二代(NHR-Ⅱ)是清华大学自主研发的反应堆,采用汽-气稳压器稳压方式。本文建立汽-气稳压器计算模型,通过与汽-气稳压器涌入实验数据进行比较验证,表明计算模型可较好地预测汽-气稳压器的动态特性。基于此计算模型,对采用一体化汽-气稳压器的NHR-Ⅱ系统稳压动态特性进行研究,结果表明NHR-Ⅱ动态功率调节过程中,系统压力和温度均出现滞后现象;在压力变化滞后阶段堆芯出口过冷度会急剧下降,但堆芯出口最小过冷度仍在安全范围内,系统安全。; NHR-Ⅱ(Nuclear Heating Reactor-Ⅱ)developed by Tsinghua University uses the integrated gas-steam pressurizer.A calculation model of the gas-steam pressurizer was developed and validated by comparing with experiment data about the pressure behavior of gas-steam pressurizer during the in-surge period.The results indicate that this calculation model can predict the transient behavior of the gas-steam pressurizer well.Then the transient characteristics of the integrated gas-steam pressurizer in NHR-Ⅱ were studied by this model.It is founded that in the power regulation of NHR-Ⅱ,the change of pressure and temperature in the system lags behind the power change in natural circulation loop with the integrated gas-steam pressurizer,and there is a sharp decline in the subcooled temperature of the core outlet.The core outlet subcooled temperature of NHR-Ⅱis within the safety range and the system is safe in the power step regulation.
