FIELD: physics; nuclear power. ^ SUBSTANCE: invention concerns method of obtaining of nuclear fuel tablets on the basis of immixed oxide (U, Pu)O2 or (U, Th)O2. Method includes: preparation of initial intermixture of powders by means of joint crushing of powder P1 from UO2 and powder P2 from PuO2 or ThO2, sifting of the gained intermixture, preparation of a terminating intermixture of powders by mixing of the undersize product with powder P3 from UO2, pelletisation of the gained terminating intermixture, sintering of tablets, and, at least, one linking chosen from oxides Cr, Al, Ti, Mg, and Va, Nb, their predecessors and the inorganic linkings, capable to introduce sulphur at a stage, enter, at least, into one of powders P1, P2, P3 and-or, at least, in an initial or terminating intermixture of powders. ^ EFFECT: major homogeneity of nuclear fuel tablets and more uniform distribution of plutonium-containing aggregations(U/Pu)O2 in the matrix UO2. ^ 17 cl, 5 dwg, 6 ex, 1 tbl |
