钠冷快堆堆芯事故往往是由于个别燃料组件冷却剂阻塞以致局部钠沸腾造成的,所以探测早期局部钠沸腾,就能防止堆芯事故的发展。钠沸腾声噪声探测是基于钠汽泡破裂发射的高频压力脉冲能在钠介质中传递,并且能区分由于泵、流体和结构等引起的低 Sodium-cooled reactor core accidents are often caused by local sodium boiling due to clogging of individual fuel assemblies, so detection of early local sodium boiling can prevent the development of a nuclear reactor accident. Sodium Boiling Acoustic noise detection is based on the high-frequency pressure pulses emitted by the sodium vapor bubble rupture that can be transmitted in the sodium medium and can be distinguished by low pump, fluid, and structure
