Nuclear-powered icebreaker "Arctic" will go to factory sea trials on diesel engines

The leading nuclear icebreaker of the 22220 "Arctic" project will go to the factory sea trials on December 12, but in emergency mode. It is reported Mil.Press FlotProm with reference to a statement by the general director of the Baltic Plant Alexei Kadilov.

The publication writes that Kadilov, speaking at a press conference on the results of the United Shipbuilding Corporation in 2019, said that factory sea trials of the Arctic icebreaker will begin on schedule, on December 12, but in emergency mode on diesel engines. The nuclear reactor will not be used, it will be prepared for start-up after returning from testing.

We were asked: let's start with diesels, and then we’ll launch it. There were a lot of alterations

- cites the publication of the words of the general director of the Baltic Plant.

At the same time, Kadilov said that the icebreaker’s readiness at the moment is 95%, its transfer to the customer will take place in 2020 in accordance with the agreement. Previously announced plans for the transfer of the "Arctic" in the spring of next year and the start of operation no earlier than May 2020 year.

The Arctic nuclear-powered icebreaker is the lead ship of the 22220 project in a series of three vessels being built at the Baltic Shipyard in St. Petersburg under a contract with Rosatom. The series also included the Siberia and Ural icebreakers, which were launched and completed afloat. The icebreaker delivery dates are 2021 and 2022 of the year, respectively.

In July of this year, it was decided to extend the 22220 series icebreakers to five ships. The contract for laying the fourth and fifth icebreakers is also concluded with the Baltic Shipyard. The delivery of the first of the new icebreakers laid down is scheduled for December 2024, the second - no later than December 2026.

A feature of the 22220 project icebreakers is the use of variable draft using ballast tanks. Double-deck ships can operate both in deep water and in shallow water in river beds, overcoming ice up to 3-meters thick without losing speed. According to project data, new icebreakers will become the largest and most powerful in the world.

The main power plant of icebreakers includes two "Rhythm-200" reactors with thermal capacity of 175 MW each. Its main advantage over other similar installations lies in its compactness and economy, as well as energy-efficient integrated layout.

But how much can such tests be considered FULL?

Good question and why such a rush? For what extra. costs, because then they will re-test with a nuclear reactor.

and why such a rush?

Apparently the END OF THE YEAR, we urgently need to tick the “missing” “ticks”, otherwise the prizes will be covered with a “copper basin” ...

[cniza]

It seems that not everyone used the funds, but they will burn ...

Tell me, svp67, have all previous atomic icebreakers experienced otherwise?
Did you turn on the reactors right away?
And if flaws were found, then the reactors were "extinguished"?

You are outraged.
Can share how to conduct tests of an atomic icebreaker.
Tell us how it should be in reality.

Or you, cniza, tell us what is the error of this solution. And why do you think that the whole point is that "not all the funds were used, they will burn, however ..."

If you have nothing to say, just put minus signs on me.

You confuse me with someone:

Be simpler and people will reach for you.

Strange, but where do you see outrage? You yourself have come up with something and make wrong conclusions on this

BECAUSE already the test program will be slightly less. The connoisseurs here divorced, everyone considers himself smarter than all shipbuilders.

[cniza]

No one considers himself smarter, but elementary things also cannot be denied - a two-way test, even if in parts, makes the project more expensive.

[Piramidon]

Quote: cniza

twice running test, even if in parts, make the project more expensive.

Again, probably not really stupid people are doing this, and apart from rattling the keys on the sites, they understand something. And, most likely, they calculated how profitable.

[cniza]

I’m only glad.

[Advisor to the Council of Advisers]

Perhaps after drank up the reactor, they’ll ride again. And now they are letting them on diesels to meet the deadline.

[cniza]

What does it mean possible, but how to test without a main power plant, and turbines?

[Advisor to the Council of Advisers]

I agree, not so put it. Of course with the reactor they will ride again, but how else. I just don't want to get ahead of myself. Since they are driving in emergency mode, there may be jambs.
I hope everything goes smoothly and without incident.

Are you up to date with all components of the test program? Of course, I did not ship, but I think that this program may include such moments as the permeability of the hull, maneuverability .. and all that can be experienced without a basic power plant.

[cniza]

Yes, of course, but this could be combined in one trial, and so there will be extra costs, even by 20 percent, but they will.

[Civil]

It will be legendary like the former "Arctic"))))

[K-612-O]

They are factory, not acceptance and not running. This is a factory test, internal.

[Carib]

As I understand it, this is the first part of the test. Then they will fix the problems, launch the reactors and the second tests. And after the second alterations and corrections, acceptance tests.

[mikh-korsakov]

Sergei! It is not a matter of full value, but of expediency. It is clear that in the process of sea trials, in view of the enormous number of different nuances, a lot of all sorts of flaws and errors will be revealed, and this is normal, because the lead ship is in the series. So wait for the end of the loading of the reactors, go out for testing and dig into the same flaws. It is better to identify them now and engage in their understanding and elimination. I think so.

[The leader of the Redskins]

Typically, ships are desired seven feet under the keel. I want to wish this hard worker no more than three ... Ice!

[Alien From]

So so so ...... I hope everything works out for shipbuilders! The country needs icebreakers both in the military-political aspect and in the economic!

[Dmitry Bolotsky]

I went through the entire Internet, nowhere did I find the characteristics of an auxiliary power plant. There are previous projects, 120 MW as the leader, but not for this project. Maybe someone knows? The article is not prepared. They said at the plant that there were a lot of tweaks, so they went out on reserve diesel power plants - they say, they should be tested anyway. The reactor is started normally. I read it in Kommersant.

[Chicha squad]

Before the New Year it is necessary to report on the tests, otherwise the prize will not be given. Let him swim at least on diesels. And yes, sure, shit floats, and the ships go. Let it be like that.

[Piramidon]

You measure only relative to the pocket and you can’t see anything further.

[Chicha squad]

Of course, love for the motherland.

[Ros 56]

So there is such a need, who will open the cards in front of us. Buran was also first tested on engines.

[Dmitriy66]

even though they test on diesels, but where are all the drunkards who wrote that the icebreaker under the bridge will not pass?
