Icebreakers. Assembly of a RITM-200 reactor for the new-generation multi-purpose nuclear icebreaker Leningrad started at one of Rosatom’s production facilities. Propulsion plants of the new nuclear-powered icebreakers comprise two RITM-200 reactors. They are twice lighter, 1.5 times smaller and considerably more powerful than the earlier versions of marine reactors, offering higher speed and better ice performance. Last year, the Northern Sea Route (NSR) set a new record, with 37.9 million tonnes of cargo transported and 92 transit voyages made. RITM-200 reactors are already installed at three new-generation icebreakers operating on the NSR, another one is undergoing sea trials, and two more are under construction. RITM reactors are also planned to be used at offshore power plants and onshore small-scale generation facilities, such as the Yakutia NPP.
