en.Wedoany.com Reported - Experts from Afrikantov OKBM, the machine-building division of Rosatom, have completed the development of an onboard simulator designed for the crew of the lead nuclear-powered icebreaker "Rossiya" (Project 10510), whose operation is supported by the RITM-400 marine reactor system.
This new hardware and software system is designed for training the crew in operating the RITM-400 nuclear power plant before the vessel is put into service, maintaining crew skills, ensuring reliable operation of the nuclear-powered ship, and safe navigation along the Northern Sea Route. The onboard simulator is based on a mathematical model that simulates the internal physical processes of the reactor in real-time, allowing for comprehensive simulation of various operational scenarios for the icebreaker's key power equipment, from normal operation to equipment failures.
Igor Zotov, Deputy Head of the Department for Mathematical Modeling and Simulator Development at Afrikantov, stated that the onboard simulator is a training tool that reproduces operational information from the central control panel instruments, simulates the operation of all nuclear power plant systems, and, based on a methodology integrating nuclear and digital technologies, lays the foundation for the safe and sustainable development of shipping in high-latitude regions.
The development of this hardware and software system utilized the experience of the Afrikantov Design and Machine-Building Plant in supercomputing and mathematical modeling, which was previously used to create digital twin models for nuclear power plants. Currently, the onboard simulator has been installed and tested at the plant's facilities, and it is expected to be used by at least 200 people.
The RITM-400 reactor was developed for the next-generation Project 10510 nuclear-powered icebreakers. It is an improved version of the RITM-200, with its thermal power increased to 315 MW, exceeding that of all existing marine reactors worldwide. The Afrikantov Design and Machine-Building Plant is the chief designer and complete supplier of this system. In 2025, Rosatom engineers manufactured two RITM-400 reactor units for the "Rossiya." The vessel is still under construction in the Far East and, upon entering service, will become the world's most powerful icebreaker, promoting the development of the Arctic and the eastern section of the Northern Sea Route.
Afrikantov OKBM provides comprehensive work and services covering the entire lifecycle of various reactor systems, serving as both the chief designer and complete supplier of reactor system equipment. It is a member of Rosatom's Machine-Building Division and the Russian Union of Mechanical Engineers.
