Abstract

In response to the insufficient qualitative and quantitative detection of thimble tube wear using conventional BOBBIN probe, it was proposed for the first time to use array eddy current testing technology to study thimble tube wear. This method is more conducive to accurately characterizing the distribution patterns and morphological features of thimble tube wear. Through simulation and experimental analysis, it was found that the experimental test results of the array were basically consistent with the simulation. It was proven that array eddy current can enhance the detection capability of BOBBIN probes, improve the detection process, significantly enhance the qualitative and quantitative level of defect detection, and have significant implications for guiding the maintenance of sleeve tubes in nuclear power plants. it also fills the gap in array eddy current testing of thimble tube in domestic nuclear power plants.
