The universal nuclear icebreaker Yakutia will become the fourth Russian icebreaker of the 22220 Project with RITM-200 reactors
MSZ Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC, belongs to Rosatom TVEL Fuel Company, based in Elektrostal, Moscow Region) manufactured and shipped nuclear fuel for the second reactor of the universal nuclear icebreaker Yakutia being built at the Baltic Shipyard in St. Petersburg.
The core for the first of the two reactors of the power unit was delivered in December 2023. Thus, the future vessel of the Russian nuclear fleet has the full supply of nuclear fuel. Having been accepted, the fuel assemblies will be loaded into the reactor.
Project 22220 universal nuclear icebreakers are equipped with RITM-200 units, which belong to the fourth generation of civil marine reactors. They are designed and manufactured at the facilities of Rosatom Mechanical Engineering Division. The integrated RITM-200 unit consists of two reactors with a thermal power of 175 MW each. Its main advantages are compactness and efficiency ensuring the vessel double draft and improved performance in terms of speed and icebreaking capability. Such units also feature a large energy resource (2.25 times exceeding the energy resource of the cores onboard the nuclear icebreakers of the 50 Let Pobedy type).
The Russian nuclear fleet already includes three universal nuclear icebreakers – Arktika, Sibir and Ural. However, the core for the universal nuclear icebreaker Yakutia features an important innovation: thermometer sleeves of a new design (having undergone the acceptance test, the equipment has gone into production with “O1” symbol). This modernization makes the heat removal recording more accurate during operation. The serial universal nuclear icebreaker Yakutia is scheduled to be commissioned at the end of 2024.
“The core for universal nuclear icebreakers is mass produced, but the last fuel batch for the Ural icebreaker was produced four years ago. Considering that, the decision was made to put its new components to qualification tests which were successful. The next universal icebreaker for which MSZ JSC is to produce cores is the universal nuclear icebreaker Chukotka that is under construction,” commented Alexander Shein, Project Manager, Special Equipment Production, MSZ JSC.
Russian nuclear icebreaker fleet now includes seven vessels: the universal nuclear icebreakers Arktika, Sibir, Ural, as well as nuclear-powered ships Yamal, 50 Let Pobedy, Taimyr and Vaigach. MSZ JSC is the only Russian producer of fuel for nuclear icebreakers.

The development of the Northern Sea Route as a major logistics corridor is a national strategic priority. To increase the NSR cargo shipping is of paramount importance for fulfilling the tasks set for the comprehensive development of the Russian Arctic. This corridor development is being ensured through cargo shipping on a regular basis, construction of new nuclear icebreakers and modernization of the relevant infrastructure. Rosatom is actively involved in these activities.
