Since 2001, a series of five irradiation test campaigns for atomized U-Mo dispersion fuel rods, KOMO-1, -2, -3, -4, and -5,has been conducted at HANARO (Korea) in order to develop high performance low enriched uranium dispersion fuel forresearch reactors. The KOMO irradiation tests provided valuable information on the irradiation behavior of U-Mo fuel thatresults from the distinct fuel design and irradiation conditions of the rod fuel for HANARO. Full size U-Mo dispersion fuelrods of 4-5 g-U/cm3 were irradiated at a maximum linear power of approximately 105 kW/m up to 85% of the initial U-235depletion burnup without breakaway swelling or fuel cladding failure. Electron probe microanalyses of the irradiated samplesshowed localized distribution of the silicon that was added in the matrix during fuel fabrication and confirmed its beneficialeffect on interaction layer growth during irradiation. The modifications of U-Mo fuel particles by the addition of a ternaryalloying element (Ti or Zr), additional protective coatings (silicide or nitride), and the use of larger fuel particles resulted insignificantly reduced interaction layers between fuel particles and Al.
