Nuclear icebreaker Yamal, 2015. A nuclear-powered icebreaker is an icebreaker with an onboard nuclear power plant that produces power for the vessel's propulsion system. . Although more expensive to operate, nuclear-powered icebreakers provide a number of advantages over their diesel-powered counterparts, especially along the Northern Sea Route where diesel-powered icebreaker operations are ...
The result, Project 10510, was a nuclear-powered icebreaker design intended for escorting cargo ships and tankers with a beam of 50 metres (160 ft) and deadweight tonnage of 100,000 tonnes year-round along the entire Northern Sea Route. With a propulsion power of 120 megawatts, the icebreaker would be capable of maintaining an average escort ...
It is the second Russian icebreaker to bear the name; the previous Leningrad was a Moskva-class diesel-electric polar icebreaker built in 1961 and decommissioned in 1993. Unlike the new nuclear-powered icebreaker, the Soviet-era vessel was named after the city itself. [19] [20]
Project 22220, also known through the Russian type size series designation LK-60Ya, [note 1] is a series of Russian nuclear-powered icebreakers.The lead ship of the class, Arktika, was delivered in 2020 and surpassed the preceding Soviet-built series of nuclear-powered icebreakers as the largest and most powerful icebreaker in the world.
Ural under construction at Baltic Shipyard in July 2019 with another Project 22220 icebreaker in the background. The tender for construction of two additional Project 22220 nuclear-powered icebreakers, referred to as the first and second serial vessels of the project, was announced at the keel laying ceremony of the lead ship Arktika on 5 November 2013.

The onboard nuclear power plant consists of two 175 MWt RITM-200 pressurized water reactors fueled by up to 20% enriched Uranium-235 [32] and two 36 MWe turbogenerators. [33] [34] [35] The propulsion system follows the classic polar icebreaker pattern with three 6.2-metre (20 ft) four-bladed propellers driven by 20-megawatt (27,000 hp) electric ...
As before, the Saint Petersburg-based shipyard was the only bidder for the construction of the nuclear-powered icebreakers. [20] The keel of the fourth Project 22220 icebreaker was laid on 26 May 2020 [3] and the vessel was launched on 22 November 2022. [4] The vessel left for sea trials on 1 December 2024. [21]
The onboard nuclear power plant will consist of two 175 MWt RITM-200 pressurized water reactors fueled by up to 20% enriched Uranium-235 [21] and two 36 MWe turbogenerators. [ 22 ] [ 23 ] [ 24 ] The propulsion system will follow the classic polar icebreaker pattern with three 6.2-metre (20 ft) four-bladed propellers driven by 20-megawatt ...
