ABSTRACT
Correlation dependencies have been obtained to determine the burn-out and content of actinides in spent nuclear fuel based on an analysis of published experimental data on the definition of burnout and isotopic composition of spent nuclear fuel rods for samples of PWR and VVER reactor types using statistical methods. Given dependencies of the mass concentration of actinides at the end of irradiation after checking for normality correspond to the initial experimental data. These relationships may be of interest to use for non-destructive methods for the purpose of express evaluation of spent nuclear fuel burnout at all stages of the nuclear cycle.
