The method of the modeling of radiation and thermal-hydraulic characteristics of the system for ⁹⁹mTc isotope production was developed, using the Monte Carlo method for computation of radiation fields and computational fluid dynamics for modeling of thermal-hydraulic characteristics. The three-dimensional solid models of this system were developed, where system geometry was fully described and necessary initial conditions was taking into account. We considered the isotope ⁹⁹Mo production due to the (γ, n) and (n, γ) reactions and analyzed the efficiency of these reactions. To improve the efficiency of the isotope ⁹⁹Mo production and to reduce the energy deposition in the target material it is proposed to use the composite converter made of Pb + Al, Pb + Cu, Pb + Be, for which the optimal parameters were defined. Application of this method makes it possible to optimize the performance of the system for ⁹⁹mTc isotope production.
