METHOD FOR OBTAINING NUCLEAR FUEL PELLETS BASED ON URANIUM DIOXIDE Russian patent published in 2012 - IPC G21C3/58 B82B3/00 

Abstract RU 2459289 C1

FIELD: power industry.

SUBSTANCE: method consists in addition to initial fine uranium dioxide of nanodisperse uranium hydride, thorough mixing of components, drying of mixture in vacuum at 300-330°C, at which decomposition reaction of uranium hydride to metal takes place, pressing of pellets of dried product and their sintering in dynamic vacuum at 1500-1550°C.

EFFECT: increasing the content of fissile material, improving strength and heat-conducting properties of material.
