Abstract

The influence of alloying additives Al(OH)3 and TiO2 on the structure and properties of uranium dioxide fuel pellets is investigated. It is established that their introduction improves the characteristics of the macrostructure and microstructure of fuel pellets and positively affects their properties. For example, the grain size in the fuel pellet increases to 39 mm (instead of 10–15 mm in the case of usual technology), the number of large (>10 mm) pores decreases, and the strength and thermal conductivity increase slightly.
