【 摘 要 】

The technology application status of eddy current testing are expatiated based on the analysis of failure and the accident examples of NPP in-core flux thimble tube, as well as the regular inspection requirements for thimble tube both in China and abroad. In addition, according to the experience of thimble tube in-service inspection in China's nuclear power plant, the existing problems in the practical application of this technology are analyzed and studied, and feasible suggestions are put forward.
