en.Wedoany.com Reported - Rosatom's Podolsk Machine-Building Plant, located near Moscow, has completed the trial assembly of the first reactor unit for the nuclear-powered icebreaker "Leningrad," marking that the unit is ready for shipment and installation.

Trial assembly is the final stage in the multi-year manufacturing cycle of the reactor unit, during which all components and elements are precisely fitted according to the design drawings. The head of the plant stated that the completed RITM unit is the 13th in the series, following the previous delivery of 10 RITM-200 and 2 higher-capacity RITM-400 reactor units. The "Leningrad" is equipped with two RITM-200 reactors; the second unit is currently undergoing preparations for hydraulic testing, after which final assembly will commence. Currently, Rosatom's machine-building division has 15 RITM units at various stages of production, with 3 of them in the final phase. These reactors are intended for nuclear icebreakers, small nuclear power plants, and floating power units.

Five Project 22220 nuclear icebreakers are already equipped with RITM-200 units, including the lead vessel "Arktika" and the serial vessels "Sibir," "Ural," "Yakutia," and "Chukotka." The first four have been escorting commercial vessels along the Northern Sea Route for several years. The last vessel in this series is expected to be delivered in 2026. The "Leningrad" is the sixth vessel of this type, built by the Baltic Shipyard, with its keel laid on January 26, 2024. Project 22220 icebreakers are constructed by the Baltic Shipyard, part of the United Shipbuilding Corporation, and feature entirely Russian-developed electric propulsion systems, primarily designed to ensure year-round navigation in the western Arctic waters. This class of vessel features a dual-draft design, enabling operation in deep sea and at the mouths of Siberian rivers, capable of breaking through ice up to 3 meters thick and creating a channel 40 meters wide. Its overall length is 173.3 meters, beam is 34 meters, design waterline beam is 33 meters, height is 52 meters, draft is 10.5 meters/8.65 meters, minimum draft is 9.03 meters, full-load displacement is 33,540 tons, rated power is 60 MW, clear water cruising speed is 22 knots, maximum icebreaking capability is 2.8-meter-thick ice (at full power, speed 1.5-2 knots), crew is 54, and design service life is 40 years.
