Data processing and visualization of X-ray computed tomography images of a JOYO MK-III fuel assembly

Tsai, T.-H. ; Sasaki, Shinji  ; Maeda, Koji  

A method for processing and visualizing X-ray computed tomography (CT) images of a fuel assembly is developed and applied to a JOYO MK-III fuel assembly. The method provides vertical-section-like images to observe the spatial distribution of CT values in fuel pins and also supplies images that show the relationship between the linear heat rate (LHR) and radial CT-value distribution. In addition, an attempt to analyze the radial cracks in the CT images is proposed, and the results demonstrate the correlation between LHR and the radial cracks.
