Reactors were loaded onto the fourth icebreaker of the Arktika type
Loading reactors on the icebreaker "Yakutia"
"Baltiysky Zavod"
Specialists of the Baltiysky Zavod loaded two RITM-200 reactor units onto the nuclear-powered icebreaker Yakutia of project 22220 (Arktika). As noted on Wednesday, August 24, in the press service of the enterprise, the installation of reactor plants is one of the key production operations in the process of building nuclear-powered ships, during which the ship acquires a "heart" that sets it in motion.
According to the representatives of the shipyard, on August 23, a complex technological process for loading and assembling on the icebreaker Yakutia of two steam generating units of the RITM-200 reactor plant with a thermal capacity of 175 MW each was completed. The weight of one block is 147.5 tons, height - 7.3 meters, diameter - 3.3 meters.
As noted in the press service of the Baltiysky Zavod, the main advantage of power plants of this type is compactness and efficiency. They have a unique energy efficient integral layout that allows the main equipment to be located directly inside the steam generating unit casing. The service life of the reactors is 40 years, and the unique design makes it possible to make the Project 22220 icebreakers double-draft, providing improved technical characteristics of the vessel in terms of ice breaking speed.
Now the specialists of the "Baltiysky Zavod" will have to carry out the final installation of the reactor plant, its auxiliary equipment and fittings.
The universal nuclear icebreaker "Yakutia" is the fourth vessel of project 22220, which is being built at the "Baltiysky Zavod" by order of the Federal State Unitary Enterprise "Atomflot". It was laid down in May 2020. Earlier it was reported that Yakutia will be launched in November 2022.
Recall that Baltiysky Zavod handed over the lead icebreaker of project 22220 Arktika into operation in October 2020 with a faulty propulsion motor on the right shaft with the obligation of the United Shipbuilding Corporation to replace it in 2021. The ship underwent a scheduled overhaul last year.
In January 2022, Atomflot received a second icebreaker, Sibir.
In addition to Yakutia, the construction of two more icebreakers of project 22220, Ural and Chukotka, continues at Baltiysky Zavod.
Project 22220 nuclear-powered icebreakers are designed for independent escort of ships and year-round leading caravans in the Western region of the Arctic, in the shallow areas of the Yenisei and the Gulf of Ob, towing ships, as well as providing assistance and performing rescue operations in ice conditions and in clear water. Icebreakers can overcome up to 2.8 meters of solid fast ice. They will become the most powerful ships of this type in the world.
The main characteristics of the vessel:
• maximum length - 173.3 meters;
• width - 34 meters;
• side height amidships - 15.2 meters;
• draft – 8.5–10.5 meters;
• displacement - 33,500 tons.
