本文叙述了作为无损检测新方法的声发射技术在核动力工程中的应用,包括对核压力容器和管道液压试验的声发射监测;核动力反应堆容器及组件的在线连续监控等。指出声发射技术将是确保反应堆安全运行的一种很有前途的工具。但对于不锈钢等韧性材料是不够灵敏的。 This paper describes the application of acoustic emission technology as a new non-destructive testing method in nuclear power engineering, including acoustic emission monitoring of nuclear pressure vessels and pipeline hydraulic tests, and on-line continuous monitoring of nuclear reactor vessels and components. Pointed out that acoustic emission technology will be a promising tool to ensure the safe operation of the reactor. But for tough materials such as stainless steel is not sensitive enough.
