Non-destructive test for irradiated U3Si2/Al fuel plate with 4,8 gU/cm3 uranium density and 20, 40, and 60% burn-up has been done. The test includes visual inspection, radiographic image analysis, and dimension measurement using digital x-ray radiography. The non-destructive test aimed to determine the performance, integrity, and reliability of U3Si2/Al fuel plate with 4,8 gU/cm3 uranium density during irradiation at RSG-GAS. Reliability and safety of the fuel during irradiation are indicated by the absence of anomalies in the post-irradiation examination result. Three samples of irradiated U3Si2/Al fuel element (FE) with 20, 40, and 60 % burn-up were transferred from RSG-GAS to RMI hot cell 101 through transfer channel of Interim Storage Spent Fuel (ISSF). The U3Si2/Al fuel plate were then transferred to hot cell 103 for non-destructive test using digital x-ray radiography with seven shots for good resolution radiographic images. The radiographic images were evaluated to obtain data of defects and dimensions such as meat width, fuel plate width, meat-cladding distance, right-left meat- cladding boundary distance at the far side (SJ) and the near side (SD). The X-ray radiography analysis shows the presence of white spot in the middle of U3Si2/Al fuel cladding with 20% burn- up. Meanwhile, indication of surface defects and other defects were not found for the 40 and 60% burn-up samples. The dimensional measurement data show no dimensional changes, which indicates solid integrity after irradiation in the RSG-GAS. The measurement data analisis can further be used for mapping the sampling spots for the next test.]]>
