Abstract

A dry method of low density UO₂ and UO₂-PuO₂ pellet fabrication is described and analysed. The characteristics of the sintered pellets are controlled by regulating the deactivation condition as a function of the raw material properties and the pellet specifications. The main deactivation parameters as temperature, atmosphere and time are discussed and their effects on the final product are mentioned. The inhibiting effect of plutonium oxide on the deactivation efficiency is revealed. Finally, a fabrication of UO₂-30 wt.% PuO₂ pellets is taken as an example.
