The first RITM-200 reactor for the fourth serial icebreaker “Chukotka” of project 22220 went to the Baltic Shipyard

The first RITM-200 reactor for the fourth serial icebreaker “Chukotka” of project 22220 went to the Baltic Shipyard

The fourth serial nuclear icebreaker "Chukotka", being built at the Baltic Shipyard, will soon receive the first part of the power plant. The shipment of the RITM-200 reactor by PJSC ZiO-Podolsk, part of the machine-building division of the Rosatom state corporation of the Atomenergomash holding, is reported by specialized publications.

ZiO-Podolsk is completing the creation of a reactor installation for the nuclear icebreaker "Chukotka" of project 22220; the first RITM-200 reactor has already been shipped to the customer and went to the Baltic Shipyard, where it will be installed in the ship's hull. The second reactor is in the final stages of assembly and will leave for St. Petersburg before the end of the year.

The Russian reactor plant "RITM-200" is part of the main power plant of the icebreaker and includes two reactors with a thermal power of 175 MW each. Its main advantage over other similar installations is its compactness and efficiency, as well as its energy-efficient integral layout, which makes it possible to make the icebreaker double-draft, i.e. capable of operating both in deep water and in river beds, thereby replacing two types of icebreakers.

The fourth serial universal nuclear icebreaker "Chukotka" of project 22220 of the "Arktika" type was laid down in St. Petersburg at the Baltic Shipyard on December 16, 2020. The vessel is being built taking into account new technical solutions tested during tests on the lead icebreaker of the Arktika series and should be handed over to the customer in 2026.

Project 22220 icebreakers are designed to operate on the Northern Sea Route; due to their features, they can also operate in shallow water, which allows them to enter the beds of northern rivers. To date, three icebreakers of this project have already been delivered to the customer and are successfully operating in the North. This is the lead icebreaker "Arktika", which gave the name to the entire series, and the first and second serial "Sibir" and "Ural". At the moment, a decision has been made to build a series of seven icebreakers of Project 22220.

    This is the information I read not to Zena from “Worthy”.
    The Burevestnik missile of unlimited flight range has successfully passed tests, Russian President Vladimir Vladimirovich Putin announced on October 05, 2023. Numerous commentators, both Russian and foreign, discuss in every possible way the use of a new type of weapon, but in fact it is not a weapon.
    RD-0410 is almost three times superior to the most powerful serial liquid rocket engine of the USSR/Russia RD-173 (Specific impulse Vacuum: 337,2 s (3308 m/s) Sea level: 309,5 s (3036 m/s). The technical parameters of the Burevestnik nuclear engine are classified, but it is known that the working fluid (air) is heated not directly in the reactor, but by a heat exchanger - most likely using molten metal as a coolant. it is relatively easy to detect this cruise missile. To create a nuclear-powered planetary aircraft based on the Burevestnik cruise missile, it is necessary to replace the working fluid “air” that creates jet thrust with the working fluid “gas”. You get something like this design, developed 50 years ago. Plus a tank with hydrogen or, what allows you to make a double-circuit scheme - with water.Yes, in fact it will be a steam rocket engine, the tank of which can be refueled from the lunar base or from icy planetoids in the Main Belt of asteroids and satellites of the giant planets.
    It is quite possible, based on the KR Burevestnik engine (two or three engines), to create a single-stage “space plane” capable of taking off from water and independently reaching the orbit of at least the Moon.
    You can assemble such a machine in Severodvinsk (the experience of creating submarines will be very useful), launch from the Barents Sea, accelerate over the Urals-Siberia and enter a low reference orbit (LEO) over the Sea of ​​Okhotsk, and from LEO to the Moon. There you can fill the tanks with water and head to Mars. How do you like that, Elon Musk?

      there is no nuclear trace, what kind of reactor protection is there, if true, then some super new materials (the Soviet school of materials science which China so lacks)

    . This is precisely the topic about which one can say - Ahead of the rest!

    I’ll throw some beauty from the Arctic, from the captain of the Nuclear icebreaker “50 Let Pobeda” Dmitry Labusov. 50 Let Pobeda is now on duty in the Laptev Sea. Photo of the sunrise is in the area of ​​Cape Chelyuskin, Mishka was caught at lunch, khan tuleshke

    what a blessing that the dirty hands of Chubais and co. did not reach the nuclear industry

      You simply don’t know Chubais and others like him. They have shares from all Russian enterprises, even a thousandth share of these shares allows them and their descendants to live comfortably for a thousand years. soldier
