摘要：
An algorithm for direct Monte Carlo modeling of the isotopic kinetic is described. The nuclear reactions, including those that change the isotopic composition (n, alpha), (n, 2n), and others, are recorded for each neutron or group of neutrons when performing a Monte Carlo calculation of neutron transport. At the same time as the neutron transport calculations, the change of the concentration of the nuclides and the irradiation time are calculated on the basis of the number of recorded interactions and energy released. The computational results presented show that it is in principle possible to apply this approach to isotopic kinetic problems.
