The invention relates to the nuclear industry, and more particularly to technology for producing a ceramic nuclear fuel for fuel rods of a nuclear power plant. The claimed method for producing uranium-gadolinium nuclear fuel comprises preparing an initial powder of uranium dioxide, mixing the latter with a powder of triuranium octoxide and gadolinium oxide, granulating the powder mixture, mixing the granulate with a solid lubricant, compressing the moulding powder, sintering the pellets produced, and polishing said pellets. A portion of a blowing agent is added to the powder at the granulation step and the remaining portion of the blowing agent is added at the step of mixing the granulate with the solid lubricant. The method makes it possible to achieve stable technological characteristics of uranium-gadolinium pellets, namely the optimal density and porosity of the fuel pellets, which have a direct effect on the thermal stability parameters of the pellets. The technical result of the invention consists in achieving thermal stability of the pellets, which aids the safe use of the fuel in a reactor.
