Popis:	Experimental data on the content of U, Pu, Np, Am, Cm, Nd, and Cs isotopes in a sample of WWER-1000 (1000 MW water-cooled water-moderated energy reactor) spent nuclear fuel with the burn-up of up to 70 GW day (t U)−1 are reported. The data were mainly obtained by isotope dilution followed by mass-spectrometric determination. The burn-up was determined from the weight fractions of 148Nd and 134,137Cs in U. The data obtained can be used for the development of low-waste cost-saving technolofy for reprocessing highburn-up SNF and for the improvement of calculation methods and programs intended for calculation of the burn-up and nuclide composition of SNF from WWER reactors.
