FIELD: power engineering.
SUBSTANCE: method to make nuclear fuel pellets includes mixing of a nuclear fission material powder, at least one auxiliary component selected from the following variety: burnable absorbers, expanding agents and alloying additives and a liquid organic plasticiser, at least one auxiliary component is added as a filler into the liquid organic plasticiser and is homogenised, the produced suspension is foamed to a stable condition. For mixing a substrate is used, which includes at least a powder of the nuclear fission material, and the produced suspension, with subsequent pressing and baking.
EFFECT: method ensures development of a regulated microstructure of nuclear fuel pellets and improvement of their quality in part of volume properties homogeneity.
