An algorithm is proposed for performing neutron-physical calculations of a reactor using digital signal processing methods. It is shown that the algorithm’s combined use of the classical methods of numerical analysis and high-frequency digital filters makes it possible to calculate accurately and rapidly the neutron macrofield on a coarse grid and to organize the neutron-physical calculations in a new way, greatly reducing the number of iterations on a fine grid. Computer modeling shows that even for a one-dimensional reactor the proposed rational combination of the computational results on coarse and fine grids gives a several-fold reduction of the computing time.
