The oxide layer in samples taken from an irradiated Zr-2.5Nb pressure tube from a CANDU-PHWR reactorwas analyzed using electron probe microanalysis (EPMA). The examined tube had been exposed totemperatures ranging from 264 to 306 oC and a neutron fluence of 8.9 × 1021 n/cm2 (E > 1 MeV) for themaximum 10 effective full-power years in a nuclear power plant. Measuring oxide layer thickness generallyemploys optical microscopy. However, in this study, analysis of the oxide layer from the irradiatedpressure tube components was undertaken through X-ray image mapping obtained using EPMA. The oxidelayer characteristics were analyzed by X-ray image mapping with 256 × 256 pixels using EPMA. In addition,the slope of the oxide layer was measured for each location. A particular advantage of this study wasthat backscattered electrons and X-ray image mapping were obtained at a magnification of 9,000 when20 kV volts and 30 uA of current were applied to radiation-shielded EPMA. The results of this studyshould usefully contribute to the study of the oxide layer properties of various types of metallic materialsirradiated by high radiation in nuclear power plants.
