To master the liquid helium transfer method correctly is of a great important sig-nificance in economy for reduction of the liquid helium precool amount, full use of the liquidhelium cool amount and increase of the transfer efficiency of liquid helium In this paper the construction and use demands of the liquid helium transfer tubes,liquidhelium precool and transfer methods are presented.

正确掌握液氦输送方法，对减少液氦预冷量、充分利用氦气冷量和提高液氦输送效率有着十分重要的经济意义。

The hot helium temperature follows HTR-10's nuclear power changes slowly, and there is a large coupling between them, so the RPHHT system adopts cascade control, the minor loop is fast, and the major loop is hot helium temperature control loop whose dynamic response is slow; there is also a large coupling between main helium loop and steam-water loop, and both the main steam temperature measure signal and the heating process of the once-through steam generator are delayed, therefore, the MHFMST applies cascade control, the minor is main helium flow control loop whose dynamic response is fast, and the major is the main steam temperature control loop whose dynamic response is slow.

本文运用机理建模法，建立了HTR-10系统动态控制模型，然后进行了动态性能仿真，将堆芯用集中参数表示，冷却剂按一维流动处理；直流蒸汽发生器按二回路工质不同的相分为预热段、蒸发段和过热段，建立了三环节控制模型，得到HTR-10系统控制模型；仿真结果与数值计算结果对比表明，本文所建立的控制模型，能近似地反映HTR-10的动态特性，适合设计控制系统。
