摘要：
The results have been presented of radiochemical analysis of 8 samples of nuclear fuel irradiated in a VVER-440 reactor. The procedures have been described for the radiochemical separation and analysis of nuclides of uranium, plutonium, americium, curium, neodymium, cesium, cerium, samarium, europium, gadolinium, neptunium using radiochemical and instrumental techniques, including ion exchange chromatography, alpha, gamma, and mass spectrometry. The data on isotopic composition, mass content of nuclides, and fuel burnup, calculated by the method of heavy atoms and by accumulation of burnup monitors Nd145+146, Nd-148, have been reported.
