Summary:The use of extended libraries of one-group cross-sections in precision nuclide composition calculations confirms the importance of including high-threshold reactions in the libraries. Particular attention is paid to impurity nuclides, which are increasingly relevant in solving problems of nuclear engineering. The existing ambiguity in the formation of extended libraries with high-threshold reactions leads to markedly different concentrations of individual nuclides, including impurities. The effect of extended libraries on the calculated nuclide composition is presented for steel irradiated with a neutron flux of 2.7 ∙ 10 15  s −1  cm −2 for an irradiation time ranging from 10 to 1000 days.
