The paper is devoted to the definition of an analytical expression for estimating the burnout depth of nuclear fuel depending on its enrichment level, the periodicity of fuel overloads, heat intensity and the duration of the time period between fuel overloads (reactor campaign) in a wide range of changes in key parameters for different types of thermal neutron reactors. The analytical expressions obtained in the work for the burnout depth are compared with numerous neutron physics calculations and experimental data from different authors for uranium fuel enrichment up to 9%. Calculations of the fuel share of the cost of electricity of nuclear power plants with PWR type reactors have been performed and its sensitivity to changes in the depth of burnout and enrichment of fuel, the frequency of its overloads, as well as to market prices for natural uranium, conversion, enrichment, fabrication of fuel assemblies and SNF handling has been determined.
