RITM-400: Russia’s MONSTER Nuclear Reactor for World’s Largest Icebreaker

In September 2025, Russia finalized the production of two RITM-400 nuclear reactors for the world’s most powerful icebreaker, Project 10510 “Leader.” Built at the Zvezda shipyard in the Russian Far East, this ship—officially named “Russia”—will measure 209 meters in length, displace 68,000 tons, and break through ice up to 4.3 meters thick, unmatched in global shipbuilding. Delivery is planned for 2027. The RITM-400 is a next-generation reactor producing 315 MW of thermal power each, twice as powerful as the widely used RITM-200 reactors on Arktika-class ships like Arktika and Siberia. Unlike older Soviet-era OK-900 or KLT-40 series reactors, the RITM-400 integrates its steam generators into the reactor vessel, reducing size and weight while increasing efficiency. This makes it the most powerful marine nuclear reactor ever built, surpassing even many Western naval propulsion systems in output, though operating on low-enriched uranium below 20% U-235 for compliance with non-proliferation rules. The new icebreaker is a centerpiece of Russia’s Arctic strategy, enabling year-round cargo navigation along the Northern Sea Route and opening access to untapped resources. Its nuclear heart—the RITM-400 pair—represents the peak of Russian civilian marine nuclear engineering. With 10 RITM-200 reactors already in service and now the first two RITM-400s completed, Russia is expanding its fleet of advanced marine reactors. Global comparisons highlight its significance. The American S8G naval reactors output between 150 and 210 MW, while reactors on U.S. aircraft carriers like the A4W and A1B exceed 500 MW but are military-only. No civilian or commercial marine reactor rivals the RITM-400 in both compactness and output, making it unique worldwide. With innovative fuel design, accident-tolerant materials, and extended refueling intervals, the RITM-400 enables the Leader icebreaker to operate autonomously in extreme conditions for long periods. This project not only secures Russia’s dominance in nuclear-powered icebreaking but also cements its role as the global leader in Arctic navigation technology. #Russia #Nuclear #Icebreaker #RITM400 #Project10510 #Arctic #Shipbuilding #NuclearEnergy #Technology #Engineering Be a Member for exclusive privileges -    / @altitudeaddicts   Twitter : https://x.com/AltitudeAddicts Website: https://www.altitudeaddicts.com
