Rosatom, PUBLISHED 16.11.2025

Rosatom's Fuel division has manufactured the cores for both nuclear reactors installed on board the Chukotka icebreaker, a universal nuclear icebreaker currently under construction.

These cores consist of fuel assemblies, control rod absorbers, emergency rods, and shells for control rods.

These components have the approvals from the Russian Maritime Register of Shipping. They will be transported to the Baltic Shipyard in St. Petersburg and installed in the starboard and port side reactors of the Chukotka icebreaker.

The Chukotka universal nuclear icebreaker is the fifth vessel of Project 22220, which is being constructed based on the order from Rosatom. Project 22220 icebreakers are equipped with the fourth generation civilian propulsion reactor units RITM-200.

The RITM-222 unit consists of two reactors with a thermal capacity of 175 megawatts each. The main advantage of the unit is its compactness and efficiency, which enables the icebreakers to operate with dual drafts and enhances their speed and icebreaking capabilities.

Safe navigation along the NSR is ensured with icebreaking assistance. Russia is the only country in the world that has a fleet of nuclear icebreakers. Today, the fleet comprises eight nuclear icebreakers, including the 50 Let Pobedy, Vaygach, Yamal, Taymyr, and the lead universal nuclear icebreaker Arktika (Project 22220), the universal nuclear icebreakers Sibir (Project 22220), Ural (Project 22220) and Yakutia (Project 22220).
