- Abstract
The present article reviews the innovative MNT-CUDA software package designed for engineering calculations of the neutron-physical characteristics of RBMK-1000 reactors according to the multi-group Monte Carlo method. An essential feature of the software is the ability to conduct multi-group fuel element calculations of the entire reactor volume with the restoration of in-core sensor data using the Monte Carlo method. Thanks to NVIDIA CUDA GPU parallel computing technology, a counting speed of about 0.2–1 billion neutron events per minute is achieved on a personal computer equipped with a state-of-engineering video card. The history of creating the software package from the first version to the latest at the moment, as well as some results of verification and certification are given. A brief information on the methods used in the software package is provided. The concept of building its complex architecture, the prospects for development, and the results of testing in the calculations of fast and uranium-water systems are set out.
