AbstractAbstract
[en] Full text: The second irradiation fuel experiment, KOMO-2, for the qualification test of atomized U-Mo dispersion rod fuels with U-loadings of 4-4.5 gU/cc in KAERI was finished after irradiation until 70 at%U235 peak burn-up and is subjected to IMEF (Irradiation material Examination Facility) for post-irradiation analysis in order to understand fuel irradiation performance of U-Mo dispersion fuel. Current results on PIE of KOMO -2 revealed that the U-Mo/Al dispersion fuel rods exhibit sound performance without break-away swelling, but most of the fuel rods irradiated at high linear power show the extensive formation of the interaction phase between the U-Mo particle and Al matrix. In this paper, the analysis on the PIE results, focused on the diffusion related microstructures obtained from the optical and EPMA observations, will be presented in detail. And thermal modeling will be carried out to calculate the temperature of the fuel rod during irradiation. (author)
