Determination of Two- Dimensional Distribution of Fission Products in the Irradiated Fuel Rod by Image Reconstruction Methods

Reconstruction of the radial two-dimensional of fission products using projections obtained by nondestructive transversal direction gamma scanning was evaluated, and then compared with the destructive sectional gamma scanning results. Although the nondestructive method has a little drawback compared to the destructive method in the accuracy, the former seemed to be sufficiently applicable.
