CEFR一回路钠净化系统取钠管上设置了虹吸破坏装置,并且对该装置进行相应的设计验证实验和数值模拟分析,从实验和理论分析的角度来研究该装置以非能动方式减少失钠事故中的液态钠泄漏量。对CEFR虹吸破坏装置进行设计验证实验可以确定它非能动的虹吸破坏作用,即通过虹吸破坏装置的设置,可以把热钠池液位与管道破口标高之间的液位差驱动力以非能动方式转换成为气腔与管道破口之间的压力差驱动力,从而大幅减少失钠事故中的液态钠泄漏量。通过实验可知,该装置在系统
The siphon destroying device is set on the sodium pipe of the CEFR primary sodium purifying system, and the corresponding design verification experiment and numerical simulation analysis of the device are carried out. From an experimental and theoretical analysis point of view, the device is designed to reduce the sodium loss accidentally In the liquid sodium leakage. Design verification test of CEFR siphon destruction device can determine its passive siphon damage, that is, by setting the siphon destruction device, the liquid level difference driving force between thermal sodium pool level and pipeline breakout elevation can be made inactive The conversion of the mode into a driving force for the pressure difference between the air chamber and the pipe breach drastically reduces the amount of liquid sodium leaking in the event of sodium loss. The experiment shows that the device is in the system
