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.

利用图形处理器（GPU）通过多组蒙特卡洛法计算 RBMK-1000 反应堆中子物理特性的创新软件包

本文评述了创新的 MNT-CUDA 软件包，该软件包是根据多组蒙特卡洛法设计的，用于 RBMK-1000 反应堆中子物理特性的工程计算。该软件的一个基本特征是能够使用蒙特卡洛法对整个反应堆容积进行多组燃料元件计算，并恢复堆芯内传感器数据。由于采用了英伟达™（NVIDIA®）CUDA GPU 并行计算技术，在配备了最先进显卡的个人电脑上可实现每分钟约 2-1 亿个中子事件的计数速度。本文介绍了该软件包从第一个版本到目前最新版本的创建历史，以及一些验证和认证结果。还简要介绍了软件包中使用的方法。还介绍了建立其复杂结构的构想、发展前景以及在快速和铀水系统计算中的测试结果。
