The Project 22220 nuclear-powered vessels embody the successful experience of shipbuilders and seafarers. The efficient operation of these vessels will be a determining factor in the sustainable development of shipping in the waters of the Northern Sea Route (NSR).

The nuclear icebreaker fleet is Russia's unique competitive advantage in the Arctic. Presently, three universal nuclear-powered icebreakers of Project 22220 are operating in the NSR waters: the lead universal nuclear-powered icebreaker Arktika (in operation since 2020), the first serial universal nuclear-powered icebreaker Sibir (in operation since 2021), and the second serial universal nuclear-powered icebreaker Ural (in operation since 2022). More than 90% of the nuclear icebreakers are built of Russian components.

The vessel’s dual-draft concept allows for operating it both in the Arctic and in the mouths of the polar rivers, in particular in shallower areas of the Yenisei estuary and the Ob Bay area.

The nuclear-powered icebreaker is equipped with a new-generation RITM-200 reactor unit. RITM-200 is designed by JSC Experimental Design Bureau of Mechanical Engineering named after Igor Afrikantov.

Besides, the nuclear-powered vessel is equipped with an electric propulsion system with asynchronous propulsion motors created by Krylov State Research Centre, a branch of the Central Research Institute SET. This is the first Russian development that makes it possible to complete a package solution for icebreaker control under any condition.

Construction of the universal nuclear-powered icebreakers Yakutia and Chukotka is currently underway in St. Petersburg. Project 22220 icebreakers will foster the development of NSR logistics potential.
