KAERI (Korea Atomic Energy Research Institute) fabricated MOX (Mixed Oxide) fuel pellets as a cooperation projectwith PSI (Paul Scherrer Institut) for an irradiation test in the Halden reactor. The MOX pellets were fitted into fuel rods thatincluded instrumentation for measurement in IFE (Institutt for Energiteknikk). The fuel rods were assembled into the test rigand irradiated in the Halden reactor up to 50 MWd/kgHM. The irradiated fuel rods were transported to the IFE, whereceramography was carried out. The fuel rods were cut transversely at the relatively higher burn-up locations and then theradial cross sections were observed. Micrographs were analyzed using an image analysis program and grain sizes along theradial direction were measured by the linear intercept method. Radial cracks in the irradiated MOX were observed that were generally circumferentially closed at the pellet peripheryand open in the hot central region. A circumferential crack was formed along the boundary between the dark central and theouter regions. The inner surface of the cladding was covered with an oxide layer. Pu-rich spots were observed in the outerregion of the fuel pellets. The spots were surrounded by many small pores and contained some big pores inside. Metallicfission product precipitates were observed mainly in the central region and in the inside of the Pu spots. The average arealfractions of the metallic precipitates at the radial cross section were 0.41% for rod 6 and 0.32% for rod 3. In the periphery,pore density smaller than 2 µm was higher than that of the other regions. The grain growth occurred from 10 µm to 12 µm inthe central region of rod 6 during irradiation.
