The paper describes an algorithm for simulation of the isotope kinetics of Eu absorber under long-term irradiation in reactor of the Eu-based absorber members. Regularities of variations in the absorbers isotope concentrations were studied numerically using the precision code MCU-RR. The paper presents the distribution in space of concentrations and reactivity values of Eu isotopes among the absorber members in compensating devices of the SM research reactor in comparison with the available data of experiments. Keywords: simulation algorithm, isotope kinetics, europium absorber, reactor irradiation, computational studies, concentrations and reactivity of isotopes, radial and vertical distributions, calculated results, experimental data.
