Abstract
A study has been made on the kinetics of sintering of pellets prepared from UO2powders derived from ADU at different calcination temperatures. The powders were calcined between 500° and 1500°C and the densification characteristics of the pellets made from these were evaluated for different soaking times from 10 to 1000 mts at sintering temperatures between 1000° and 1500°C. Data were analysed using the empirical equation where D is the density, C and K are constants and t denotes time. It was found that (i) the progress of sintering, (ii) attainment of limiting densities and (iii) variation in rates of densification at different temperatures and time can be explained on the assumption that material movement (hence densification) is governed by the number, nature and energy of crystalline defects (flaws) in the original powders.Keywords
