Icebreaker "Vaigach" broke the record for operating a nuclear installation

48
The Vaigach nuclear-powered ship broke the world record for the duration of the nuclear power plant’s nuclear power plant operation, Atomflot’s press service reported on Friday.


On February 16, 2018, the icebreaker Vaigach broke the record for the duration of operation of a nuclear power plant, reached by the nuclear icebreaker Arktika in August, 2008. A new record was 177,205 thousand hours (the previous value - 177,204 thousand hours)
- said in a statement.

Icebreaker "Vaigach" broke the record for operating a nuclear installation


This became possible due to the fact that in 2017, Rosatomflot specialists together with the design office of Afrikantov OKBM JSC completed work on extending the service life of the nuclear power plants of the Vaigach and Taimyr nuclear icebreakers. The operating time of the plants received a scientific substantiation and extended to 200 thousand hours. This made it possible to eliminate the emergence of an “ice break” (a period of shortage of operating icebreakers due to the expiration of the operating period of the old ones and the absence of new ships).

At the same time, the initial resource of the nuclear power plant of the icebreakers Vaigach and Taimyr did not exceed 100 in thousands of hours. Thus, the term has doubled.

This work allows the enterprise to use four atomic icebreakers efficiently.
- noted in the company.

Atomic icebreaker "Vaigach" (type "Taimyr" was put into operation in 1990 year. Its length is 151,8 m, width - 29,2 m, displacement 21 thousand tons., Power of the main installation - 50 thousand liters. With., TASS reports

              Yes, this is one of the reasons, and of course, an unsuccessful combination of several unfavorable factors leading to the accident, including the mistakes of the staff itself.

        The initial design flaws of the RBMK-1000 reactor led to the Chernobyl disaster, and not the tests, which by the way were completed and the explosion of the reactor occurred when it was shut down, to the article also planned.

          Alas, not only. The positive temperature effect of reactivity, the “wet” AZ and the displacer on the AZ rods, of course, took place. But all this was superimposed on staff errors. But whether records are needed in the nuclear fleet, as in the fleet in general, is a moot point. There were precedents, you know. in the 30s, records were set, who took longer without a dock, and as the war broke out, they were left without a merchant fleet. Experiments to extend the life of fuel rods were also carried out in the USSR. It ended sadly. During the unloading of the shell zone, they began to crumble. Maybe, of course, now technology has gone ahead.

          Who said they were finished? They were just carried out with a serious violation of the safety regulations of the reactor. But the Woodpecker didn’t want to listen when the power of the reactor fell from the values ​​that were conceived when testing the run-out of the turbogenerator rotor (((

            On April 26, 1986, at one hour twenty three minutes forty seconds, the shift supervisor of the Chernobyl NPP unit 4, Alexander Akimov, ordered the reactor to be shut off after completion of work carried out before the shutdown of the power unit for the scheduled repair. The command was given in a quiet working environment, the central control system does not record a single alarm or warning signal about the deviation of the parameters of the reactor or service systems. Reactor operator Leonid Toptunov removed the cap from the AZ button to protect against accidental erroneous pressing and pressed the button. By this signal, 187 rods of the reactor control system of the reactor began to move down into the active zone. The backlight bulbs lit up on the mimic panel, and the arrows for the position indicators of the rods came into motion. Alexander Akimov, halfway to the reactor control panel, observed this, also saw that the “bunnies” of the AR unbalance indicators “darted to the left” (his expression), as it should be, which meant reducing the reactor power, turned to the safety panel, which was observed by the experiment.
            But then what happened was something that even the most unbridled fantasy could not predict. After a slight decrease, the reactor power suddenly began to increase at an ever-increasing speed, and alarms appeared. L. Toptunov shouted about an emergency increase in power. But to do anything was not in his power. All he could do was hold the AZ button, the CPS rods went into the active zone. There are no other means at his disposal. Yes, and all the others too. A. Akimov sharply shouted: "Turn off the reactor!" I jumped to the console and de-energized the electromagnetic couplings of the drives of the CPS rods. The action is true, but useless. After all, the logic of the CPS, that is, all its elements of logic circuits, worked correctly, the rods went into the zone. Now it’s clear - after pressing the AZ button there was no right action, there was no means of salvation. Another logic failed!
            With a short interval, two powerful explosions followed. The AZ rods stopped moving, not having completed half the way. They had nowhere else to go.
            At one hour, twenty-three minutes, forty-seven seconds, the reactor was destroyed by acceleration of power by instant neutrons. This is a crash, the ultimate catastrophe that could be in an energy reactor. They did not comprehend it, did not prepare for it, no technical measures for localization at the block and station were provided. There are no organizational measures.

              To begin with, he held the KG button, not the AZ. For the latter, you do not need to hold it, clicked and that's it. It is necessary to hold it in AZ pickup mode so that it does not go down. But at that moment, it was too late. The temperature rising in the first circuit already accelerated the reaction faster than the groups of absorber rods went down. And then it was the AZ discharge that led to acceleration by instant neutrons. The fact is that, unlike VVER, a wet type AZ is installed at RBMK, however, like KG. On VVER, absorbent rods fly into dry pipes in fractions of a second and extinguish the reaction instantly. At RBMK, AZ pipes are pumped with water, so the rods go down more slowly - once, and a “displacer" is installed at the ends of the rods, which pushes out water - two. The absorbing capacity of the displacer (stainless steel) is even less than that of the surrounding materials of the zone, which led to an additional surge in power, boiling of the coolant and rupture of the reactor. At least about this analysis was given to us by professor Kuznetsov, the author of all textbooks on ship automatic control systems.

              the protection did not turn off, moreover, after the end of the tests, the reactor was shut off by pressing the emergency protection button, and no one could have foreseen in a nightmare that just pressing the emergency protection button would correct the catastrophe.

      There is enough experience, but you can’t extend the life of the device forever (you shouldn’t joke with a peaceful atom as well). The installation resource was doubled-well done (they sat at the table and decided to limit the installation capacity to a certain percentage).
      It does not solve the problems — new ones need to be built.
      I’ve been talking with guys from OKBM for a long time, smart engineers (although they don’t send stupid businessmen on business trips). Although there were some funny things like “What the hell ....” “I” did it for a minute pause, that's why I arrived, ”
      Then, on-line changes were made to the design of the product, it works without complaints. Its topic is handling equipment.

        So they build smile And the extension of the resource in anticipation of the renewal of the icebreaker fleet
        This made it possible to exclude the occurrence of an “ice break” (a period of shortage of existing icebreakers due to the end of the working life of old and the absence of new vessels).

Among the icy spaces and the polar night, a handsomely bright man, illuminating the paths with the help of searchlights, is able to break severe ice and move in spite of difficult conditions to his goal, thanks to the coordinated actions of the crew and an experienced captain.
    The icebreaking fleet of Russia and its people is our beauty and pride.

      Honestly, it’s not very good ... If you take the first Vaigach icebreaker, then yes, it was laid down in 1907 in St. Petersburg at the Nevsky Shipyard, launched in 1908, and entered service in 1909. But the atomic, not so complete, hull was laid down at the Holstrom Histalahti shipyard of the Vyartsilya Marine Technique concern in Helsinki (Finland). But I agree that the ships are beautiful, and most importantly NEEDED.

            I always considered your comments to be objective, but let me disagree here.
            All project documentation for the building, superstructure, decoration was really provided by us by Vyartsilya, except for saturation of the automatic control system. By the way, all the metal for the construction of icebreakers was also supplied by us. For information, most of Russia's non-nuclear icebreakers were built there.
            Correctly said, "Sea Devil" in part, there were no free slipways with us. And not from a good life, we loaded the Finns shipyards.

      The hummocks were wrinkled
      On the face of the ocean white plaster.
      A blizzard roared like a heart-rending howl
      Entangled in the antennas of an icebreaker,
      And like in a Pushkin’s blizzard then,
      Perhaps someone’s fate has split.
      A gray-haired dawn rises over the Arctic
      Over the Arctic, a frosty crisp smell,

      And with a caravan moves west.

    I’ll insert my 5 cents. 177,205 thousand hours is 20,22 years (twenty years and two and a half months). I don’t see anything special here. One transport nuclear power plant worked for 23 years and 5 months without any complaints. Of the two basics, only one went into an acceptable state, but was operational. And yes, I am very negative about all measures to extend the service life (or operation) of a nuclear power plant. The constructor inadvertently laid in them: 10 years of operation, then repair. Then again 10 years of operation. And all extensions are from poverty. And by the way, a stone towards OKBM. I did not understand their obstinacy, worthy of a better application, regarding the washing of GHGs. We rested for a long time, but in the end, the decision was made in the upper echelons. Washed was carried out - PGPG flowed ... That's all, hello nuclear power limitation.
