Defect Detection of Nuclear Piping System by Information Fusion Technology

The defect features of nuclear piping were summarized and analyzed.Based on the principle of multi-sensor information fusion technology,the defect information fusion mode and method were determined and the spatial-temporal fusion flow of defect information based on D-S Evidence Theory was estimated.The results of emulation and fusion calculation indicate that this method can make full use of the mutual information by multiple methods of defect detection and historical data,through which we can judge the defect of nuclear piping rapidly and precisely.The results can give a beneficial reference for improving the probability and the intelligent level of defect detection of nuclear piping.
