MCU Code Implementation of the Calculation of Functionals in Volumes of a Supplementary Geometry

Resumo

The implementation in the MCU software complex of methods and algorithms for calculating the neutronphysical characteristics in volumes set with the aid of a supplementary geometry, which is not related with the main geometry and determines exclusively the regions of calculation of functionals and not the construction of the system being modeled, is described. Three types of supplementary geometry for Monte Carlo modeling of particle trajectories in hexagonal, cylindrical, and rectangular detection networks are implemented. These method and algorithms have greatly simplified the process of setting the initial data, increased the reliability of the calculations and the universality of the code in solving complex problems such as the calculation of the spatial distribution of the energy release and the flux density in models of power reactors.
