Abstract

The interaction layers (ILs) observed in the SELENIUM plates show irregular appearance and an abrupt growth at the regions with a fission rate ≥ 7x1014 fissions/cm3/s. The formation and growth mechanism of the IL in coated particles was investigated by applying the radiation enhanced diffusion model used for understanding ion beam mixing. IL thickness and volume fraction were calculated using the IL growth correlation for U- Mo/Al dispersion fuels with a pure Al matrix, which is expressed as a function of fission rate and temperature. The calculation results suggest that the IL in coated particles started to form from the beginning of the irradiation and its accelerated growth at high fission rate regions is a temperature effect.
