核电站一回路管道在有泄漏时,管道内的水蒸汽喷出将使漏点周围空气中的湿度发生变化。本工作就是利用湿敏元件组成的探测器测量湿度变化来确定管道上漏点的位置。研究包括三方面的内容:(1)研制了能抗10~7伦琴γ辐照、能耐250℃水蒸气、结构简单可靠、去湿迅速、体积小、性能稳定、响应时间短、有较好的感湿性能、价格 When there is a leak in the pipeline of the primary circuit of a nuclear power station, the water vapor in the pipeline will cause the humidity in the air around the leak point to change. This work is the use of humidity sensors composed of detectors to measure changes in humidity to determine the location of the leak on the pipe. The research includes three aspects: (1) Developed a gamma radiation resistant to 10 ~ 7 roentgens, capable of resisting water vapor at 250 ℃, simple and reliable structure, rapid dehumidification, small volume, stable performance, short response time and good Smell wet performance, price
