A theoretical and calculational justification of the U shell (pusher) using to significantly increase the energy yield was previously made for the hybrid inertial heavy ion fusion power micro-target. This justification included the accounting for the neutron-nuclear reactions in the pusher, formulated as generalized Akhiezer and Pomeranchuk solutions for cylindrical symmetry. This paper shows the results of such micro-target study basing on a later more comprehensive mathematical model describing the neutron-nuclear processes in the multi-group approximation. The process of micro-target implosion is described in the 3-temperature hydrodynamic approximation with account for the thermonuclear reaction kinetics, typical for the deuterium-tritium fuel. The paper includes the results of optimized calculations, proving the prospective character of the hybrid inertial heavy ion fusion micro-targets when the natural uranium is used as the pusher material.Keywords: hybrid micro-target, neutron transport equation.
