Russia's state nuclear corporation Rosatom has achieved a monumental milestone in its ambitious Arctic development program: the completion of the advanced RITM-400 reactor for the future nuclear icebreaker "Rossiya." This formidable vessel is set to become the most powerful nuclear icebreaker globally, a true titan of the Arctic seas.
The crucial production work was undertaken by Atomenergomash (AEM-Technologies), Rosatom's machine-building division, specifically at its Volgodonsk branch.
The RITM-400, a cutting-edge, new-generation reactor, boasts an impressive thermal power of 120 MW. Its successful completion signifies a major step forward in equipping the "Rossiya" (also known as LK-120Ya) for its challenging mission.
The "Rossiya" is not just another icebreaker; it is a strategic asset designed to revolutionize year-round navigation along the Northern Sea Route (NSR).
This includes the often treacherous and ice-bound eastern sector of the route, where its immense power will be indispensable for leading large convoys of vessels, ensuring safe and efficient passage through the Arctic's formidable conditions.
Currently, the construction of this groundbreaking icebreaker is progressing at the Zvezda shipyard, one of Russia's most modern shipbuilding facilities.
The integration of the newly completed RITM-400 reactor will propel the "Rossiya" closer to its operational debut, promising unprecedented capabilities in maintaining Russia's presence and economic activities in the High North.
This achievement underscores Russia's unwavering commitment to developing the Arctic as a vital transport corridor and resource base.
The "Rossiya," powered by its advanced RITM-400 reactor, will be a beacon of innovation and strength, solidifying Russia's leadership in Arctic maritime operations for decades to come.
