AbstractThe paper analyzes the impact of spent nuclear fuel of WWER-1000 reactors of various operating conditions, such as the concentration of boric acid dissolved in water, the temperature of the fuel and others on the isotopic composition. Another factor of influence is the technical characteristics implemented in the production of fuel assemblies, in particular the mass of fuel, its enrichment and other mass-dimensional characteristics of fuel assemblies (FA). Calculations are carried out on models of fuel assemblies of the WWER-1000 reactor. The basis was taken of a typical fuel assembly of the Russian suppliers of fuel elements and fuel assembly of the Westinghouse American company.
