Radioactive corrosion product specimens were analyzed using an electron probe microanalyzer (EPMA) andX-ray image mapping. It is difficult to analyze the composition of radioactive corrosion products usingan EPMA due to the size and rough shape of the surfaces. It is particularly challenging to analyze thecomposition of radioactive corrosion products in the form of piled up, small grains. However, useful resultscan be derived by applying a semi-quantitative analysis method using an EPMA with X-ray images. Astandard-less, semi-quantitative method for wavelength dispersive spectrometry. EPMA analysis was developedwith the objective of simplifying the analytical procedure required. In this study, we verified the reasonabletheory of semi-quantitative analysis and observed the semi-quantitative results using a sample with a goodsurface condition. Based on the validated results, we analyzed highly rough-surface radioactive corrosionproducts and assessed their composition. Finally, the usefulness of the semi-quantitative analysis was reviewedby verifying the results of the analysis of radioactive corrosion products collected from spent nuclear fuelrods.
