氦气系统主要功能:1)用氦气作载体将重水箱及重水贮存罐的内爆炸性气体带出,并将其合成重水回收;2)向重水箱和重水贮存罐提供氦气覆盖,以确保重水纯度;3)必要时可向系统补充氧气,以确保氘、氧的合成;4)必要时系统提供一定压力的氦气用于将重水收集罐的重水输送至重水贮存罐。模型示于图1。
The main functions of the helium system are as follows: 1) Helium is used as a carrier to carry the explosive gas in the heavy water tank and the heavy water storage tank and recover the synthetic heavy water; and 2) helium gas coverage is provided to the heavy water tank and the heavy water storage tank to ensure Heavy water purity; 3) If necessary, oxygen may be supplied to the system to ensure the synthesis of deuterium and oxygen; 4) If necessary, the system supplies a certain pressure of helium gas to transport the heavy water from the heavy water collection tank to the heavy water storage tank. The model is shown in Figure 1.
