The problem of simulating neutron-nuclear processes in hybrid microtargets with an external energy source has been considered. A mathematical model of interaction between neutrons and nuclei based on radiation transport multigroup equations is developed. The results of the numerical calculations of the microtarget with a thin layer of 238U are presented. The influence of the neutron model various simplifications on the neutron-nuclear processes in the microtarget is shown.
