Nuclear fuel pellet inspection using machine vision and artificial neural networks

Author

Mark Le Roy Kelly

Abstract

"Nuclear fuel must be of high quality before being placed into service in a reactor. Nuclear fuel vendors currently use manual inspection to verify the quality of the nuclear fuel before the fuel pellets are inserted into the zirconium fuel rods and bundled into assemblies. This work examines the feasibility of using machine vision and artificial neural networks to perform the same task, with motivation being to improve accuracy, speed, costs, reduce employee radiation doses, and to provide defect statistics to the fuel manufacturer. Sample nuclear fuel pellets were photographed, scanned, and an appropriate feature extraction technique was developed and applied to the scanned images. The extracted features were then used as inputs to two neural network paradigms, ART2-A and backpropagation. The results of testing were then compared for the two networks. Both the ART2-A and backpropagation results are promising. Results indicate that a machine vision inspection system may be possible using a system of ART2-A networks or a single backpropagation neural network"--Abstract, page iii.
