MATHEMATICAL OPTIMIZATION MODEL OF THE TECHNOLOGY OF FUEL TABLETS FROM URANIUM DIOXIDE POWDER

摘要

The role of porosity in the evolution of the density of a sintered tablet is considered. A comprehensive mathematical model is proposed for calculation of the parameters of active and passive porosity at all stages of the technology of fabricating fuel tablets from uranium dioxide powder. The model makes it possible to optimize the regimes of production of the initial powders and tablets for the purpose of controlling their porosity in the sintering process.
