ABSTRACT
The
out-pile examinations of atomized U-Mo dispersion fuels after reaction between
U-Mo and the Al matrix at elevated temperature were carried out in order to
investigate heat generation, reaction kinetics and thermal compatibility. The heat generation of the dispersion fuels
during the thermal cycle from room temperature to 700oC was measured
employing differential scanning calorimetry (DSC). Growth rates of the reaction layer were fitted theoretically
using spherical diffusion model. The
effect of volume fraction and powdering method on the thermal compatibility of
atomized U-Mo dispersion fuels was also examined.
