More Information
Summary:The invention discloses a nuclear fuel assembly fuel rod gap automatic detection device and method, and the device comprises a miniature line laser displacement sensor, a longitudinal displacement assembly, a transverse displacement assembly, and a data collection and control system, and the miniature line laser displacement sensor is used for collecting the section data of a nuclear fuel assembly fuel rod; the longitudinal displacement assembly is used for installing a miniature line laser displacement sensor and moving in the depth direction. The transverse displacement assembly is used for installing the longitudinal displacement assembly and transversely moving, the micro linear laser displacement sensors can be sequentially driven to collect gap data of each column of fuel rods, and the data collection and control system is used for collecting measurement data of the micro linear laser displacement sensors. And outputting all array fuel rod gaps and fuel rod diameters in the nuclear fuel assembly through
