Abstract

The efficiency of different implementations of the iterative process for solving a multigroup system of transport equations on the basis of the quasi-diffusion method is considered. Computations are performed for a two-dimensional model of the core of the BN-800 reactor working in the selfadjustable neutron-nuclear regime (SANNR). The results of this work make it possible to develop efficient methods for simulating the nonstationary behavior of fast reactors in the SANNR in any multidimensional geometry.
