April 26, 1986 at the Chernobyl nuclear power plant. Lenin, the largest stories humanity radiation catastrophe. To eliminate the consequences, more than half a million people and hundreds of pieces of equipment were sent to the accident zone, among which were IMR-2 based on tanks T-72. However, these engineering obstacles, perfectly adapted to work in a nuclear war, gave up slack on the ground with the most powerful radioactive contamination.

lead armor


Looking at photographs and videos taken during the liquidation of the consequences of the Chernobyl accident, an association involuntarily arises in my head with some relatively fresh local military conflict - with the same Syria, for example. In both cases, artisanal armor was literally put on stream. Only some strengthened weak armor to protect against bullets and shells, while others - to protect against penetrating radiation.

And indeed, cars hung with lead sheets have become commonplace in the Chernobyl zone. But, if the modernization of lightly armored vehicles or the same trucks can be understood, then why did heavy WRIs go through this procedure? After all, they were considered almost the standard for working in conditions of strong radiation. This is true, but not quite.

When developing any type of combat vehicle, and the IMR-2 is also such, engineers actively use probabilistic laws. At the first stages of work, such parameters as the probability of meeting with one or another anti-tank weapon, the angle of fire, the probability of being hit in various conditions, including with different composition of the combat unit, and so on, are calculated.

A similar situation occurs with radiation. No one imagined that such a large-scale catastrophe was possible, so nuclear war was considered the main threatening factor. As a result, when designing the anti-nuclear protection of the IMR-2, the greatest attention was paid to the lower parts of the hull and the bottom, since the radiation should have come from the soil contaminated with a nuclear explosion.

In Chernobyl, everything turned out the other way around. Obstruction engineering vehicles were involved in clearing debris near the destroyed power unit, building a protective sarcophagus, breaking contaminated houses in nearby villages, uprooting trees in the Red Forest, where a large part of the radioactive fallout fell immediately after the explosion.

In all these operations, the radiation sources were not in the ground, but at a certain height - in the crowns of trees, the roofs of the power unit and houses. Radiation hit the most vulnerable place of IMR-2 - in the upper hemisphere. Therefore, thick lead sheets have become an almost indispensable attribute of this technique, working in dangerous places. But even this measure did not always help: inside the cars, the level of gamma radiation sometimes reached the mark of 15 R / hour (X-ray per hour) and even exceeded it. At the same time, for reference, a background level of up to 30 μR / h (micro-roentgen per hour) on average is considered a safe level of radiation, that is, the norm was exceeded by 500 times or more.

Subsequently, some IMR-2s went through a far from artisanal refinement, which made it possible to raise the level of protection to a factor of 1 times less radiation.

Problems with decontamination


At certain intervals, almost all equipment used in the accident zone was subjected to a decontamination procedure or, in simple terms, a total wash. Naturally, this was not done so that it could then be taken out and reused outside the radioactive lands. There was even no question of this - only burial or sending to the septic tanks for eternal parking.

The purpose of decontamination was more prosaic: to prevent the transfer of nuclides across the zone and wash away radioactive contamination from the surface and internal parts of the machines, at least to the level at which adhering dust and small debris ceased to produce a high level of radiation, which would be fatal for the crew. With this, the hero of this article had some problems.

The abundance of cavities, niches, moving parts and other external structural elements contributed to the dense jamming of dust, which could not be reached even with brushes and other tools. However, about the same difficulties were with the decontamination of other types of equipment - there are still no perfectly flat surfaces. But the matter did not end there.

In IMR-2, crew hatches are equipped with seals, which, during the operation of the filter-ventilation unit (FVU), which creates excess pressure from the inside, quite well protect against the ingress of all kinds of dust, gases and liquids. But in the case of a disabled FVU, the tightness of the hatch covers decreased sharply. As a result, when the car was washed, dousing it with a special compound, part of it, together with radioactive dust, got inside the car. And often these were not barely leaked drops, but whole streams that could even disable the machine control equipment.

A separate headache was the engine air filter. Its very purpose suggests that it will be a radioactive dust concentrator, since tens and hundreds of cubic meters of contaminated air pass through it. But in the IMR-2, serviced cassette filters were installed, which had to be cleaned periodically. Measurements showed that before cleaning the background from the filter was on average 5 R/h, and after thorough washing it was about 3,5 R/h.

It would seem that the air supply system of the engine of the machine is isolated from the crew and does not irradiate it so much. But do not forget about the attendants, because someone should clean this filter. Thus, as part of studies of accumulated radiation doses among liquidators, it was found that some employees of the technical service, who were never involved in work on radioactive terrain, but served IMR-2, including filters, received up to 9 roentgens per month.

Here, of course, the cassetteless cyclone filters of the T-64 and T-80 tanks, which are scolded and condemned in every possible way, would come in handy. The passage of dust into the engine is incomparably higher, but contact with them must be kept to a minimum.

The wishes of the exploiters


From the foregoing, it becomes clear that the main requirements of both those who directly worked on the IMR-2 and those who collected statistics on the use of these machines are the strengthening of radiation protection and the implementation of measures to facilitate decontamination. In addition, there were a couple of other wishes.

Machines, although rare, could break down right during operation and lose speed. What to do in such a case? Outside - a deadly radiation background, but you can’t stay still either. As a rule, another engineering vehicle went to the aid of the broken ones, but in order to take the suffering in tow, someone still had to go outside and carry out the hitch. Based on this, it would be preferable to automate and mechanize the coupling so that neither the rescuers nor the rescued leave their equipment and are not exposed to excessive radiation.

The second wish turned out to be a little specific, but not without reason.

It is prescribed to work in conditions of strong radiation contamination with closed hatches. In the Kyiv region, where the Chernobyl nuclear power plant was located, at the end of April 1986 it was already hot. It didn't get colder in May or June. When conditional +30 degrees Celsius and above are outside, with closed hatches inside the car, temperatures can rise up to 50 degrees. As a result, one of the crew members may feel ill or lose consciousness. To this may be added manifestations of radiation sickness, which also do not contribute to good health.

Therefore, it is desirable to have some kind of device to be able to open the hatch covers of the crew from the outside - apparently they suffered to extract the unconscious bodies of the operators, dragging them through neighboring open hatches.

Conclusion


There is no doubt that the claims against IMR-2 after being used during the liquidation of the consequences of the Chernobyl accident were a wagon and a small cart. But this machine was originally designed to solve completely different tasks: the evacuation of damaged or broken equipment from the battlefield, demining, clearing rubble or man-made barriers, and other things, including in the conditions of the use of nuclear weapons by the enemy. weapons She is like a fish in water.

What happened on April 26, 1986, no one imagined and did not lay in the backlog of engineering equipment, because it was not for nothing that even all kinds of robots and products of the space industry were used. So there is no fault of the IMR here. This once again proves that the creation of a completely universal machine is simply impossible, and some situations require specific solutions.

        Here is something else. I would like to clarify who and how calculated the degree of infection and protection of this machine, when making passes through the centers of lesions in cities, in forests, next to destroyed nuclear power plants or nuclear burial sites. Or do you think that this would not have been required in a global nuclear conflict?

          Remember the spaceports. laughing It is precisely that making passages even for wheeled vehicles in time is far from the same as cleaning up contaminated areas. They pushed / pulled apart the rubble, filled up the funnels and further, or even together with the tanks.
          And they washed along with the tanks, the same equipment. What happened in Chernobyl is precisely that non-army case.

                    Yes, yes ... In the context of a global nuclear war, these zones will be everywhere and they will be arranged by both the enemy in order to restrain our movement and inflict maximum damage, and ourselves, but in order to inflict maximum damage to the enemy and ensure the movement of our troops. Tactical nuclear weapons will be used along the front line and tanks will have to go through all the rubble and contamination zones

                      And what yes? Understand a simple thing - WRI in a breakthrough will be adversely affected just a few more tanks, for which she will provide the way and she will move in the same column or a little later, and then catch up. And wash it will be the same technique and forces, but more often (probably).

                        Such, Sergey, such:

                        But the greatest development of the machine for the preparation and maintenance of column tracks, ensuring the rapid advance of troops, clearing debris, including in urban areas, received during the appearance of nuclear missile weapons (second half of the 1960s). An increase in the volume of tasks, a change in their content, terms and conditions of implementation led to the creation of an engineering machine for blocking the IMR.

                        IMR-2 is designed for equipping passages, clearing rubble and destruction with engineering provided combat operations of the troops, including in radioactively contaminated areas. In addition, it can be used to tow damaged equipment from the path of movement of troops, to carry out rescue operations in areas of mass destruction, and the like.

                        Rapid advance of troops! Providing a database of troops! And for this you need to have mobility and maintainability comparable to military equipment. And the rest is included.

Let me remind you that in Chernobyl there was just a thermal explosion of the reactor and, to put it mildly, they spoiled a lot, and even then they were frightened due to the fact that the whole country threw resources to fix this, but what will happen when take off from nuclear weapons a dozen reactors across the country?

              This is the whole point. In Chernobyl, IMRs worked in the zone for WEEKS. And even for months. And of course, the isotopes are different, long-lived.
              By the way, in spite of everything, not all cars were decommissioned and buried. Most (about 90%) of equipment, wheeled incl. returned to the troops, though after many washes. And of course, continued to fonit on the sly. In our part, ASok drivers were called "fireflies". laughing

            Your main mistake, as well as the designers of this IMR, is that you make a distinction between the situations in Chernobyl and the actual operation of this machine in the foci of destruction, in cases of a nuclear conflict. But I don't see her. And here and there, the technique had to work for days and weeks in areas with increased radioactivity, which means that since this technique showed a low level of protection in the upper part when eliminating the Chernobyl accident, it would have shown it in a real nuclear conflict

              Where did you find such levels of pollution after a nuclear explosion - no one knows.

              In fact, the crew, for lack of a better one, will stand for 10 hours with a bare bottom at the epicenter after the explosion than spend the same 10 hours in a standard imr-2 in front of the power unit.

              I repeat once again that the levels of radiation after the explosion at the Chernobyl nuclear power plant were tens and hundreds of times higher than after a nuclear explosion. Don't talk nonsense. Nobody prepared for this.

                Bring the numbers. Explain then why it was necessary to abandon the army devices and dosimeters when working in this zone, in particular, the GO-27 devices installed on armored vehicles? I had to buy and urgently produce more sensitive devices

                  There were many places to work in Chernobyl. Not everywhere the level of radiation was measured by roentgens per hour. GO-27, judging by the information from the Internet, has a lower measurement limit of 0,2 R / h. That is, he will not notice 100 milliroentgens per hour. Perhaps that is why "more sensitive instruments" were required.

            Thank you for the article.
            Senior comrades served with me, raking radioactive shit near the reactor with "destructors". Suleimanov - Dagestan, Makeev - Moscow, Shubin - Moscow region.
            Soldiers conscripts - honestly fulfilled their military duty.
            No one then was interested in where you were from and whose reactor it was.
            My Friends from Dagestan and Moscow protected my Ukraine and our USSR.
            From what is described in the article, in general, everything is True.
            But they washed the equipment and even burned the paint, not in order to bury it, but precisely with the hope of returning it to service.
            Also during this process received additional. doses of radiation. By the way, especially then, and no one thought. "Pencils" drives often lived their lives.
            And on the IMR stalled near the reactor, I also had to manually throw a tank cable. At the same time, it is not for a selfie to get out into the "fresh air" right at the power unit.
            And about the heat, too true. Nobody put on a "painting" respirator, because the physiognomy in it was immediately "welded"
            Regarding features...
            And with what to compare? Did the German "Pioneers" show themselves better somewhere in the same conditions?
            Our unique technique, honestly worked out in a situation for which it was NOT designed. The category of measurement - "disadvantages" is generally NOT applicable in this situation.
            You have a "bayonet shovel", but you had to throw sand ... I doubt very much that when designing IMRs, it was supposed to rake up the rubble near your own nuclear power plant

            Dear Eduard, in principle, I won’t say anything critical about the main part of the publication, but I can’t get past this, sorry!
            In IMR-2, crew hatches are equipped with seals, which, during the operation of the filter-ventilation unit (FVU), which creates excess pressure from the inside, quite well protect against the ingress of all kinds of dust, gases and liquids. But in the case of a disabled FVU, the tightness of the hatch covers decreased sharply. As a result, when the car was washed, dousing it with a special compound, part of it, together with radioactive dust, got inside the car. And often these were not barely leaked drops, but whole streams that could even disable the machine control equipment.
            I don’t know who you are by profession, but I have been in motorized rifle and tank units for more than a dozen years .... You know, we have a lot of armored vehicles in the parks of military vehicles for months in open parking lots, not being covered with awnings, but only with closed hatches ... and something no streams flowed into the equipment, although there were a lot of rains and showers! Yes, and at the washes, the tanks were washed with hoses ... and something didn’t get numb and didn’t spoil the equipment ... Moreover, if you don’t know, the hatches of the tanks open outward, because the working HVU, creating excess pressure inside the tank, is already cannot in any way contribute to a denser fit of manhole covers, but quite the opposite ... !!! wink The essence, in this case, of the action of the excess pressure of the FVU is that if there is, for example, some damage to the sealing gum of the hatch, violating the tightness in this place, simply in this place the air will be etched from the inside to the outside (due to excess pressure ), preventing penetration into the OM and radioactive dust.

          And what do you want from a machine that is equipped with external moving equipment? But I have no doubt that the IMR is much better adapted to this than a civilian bulldozer and a crane-manipulator, and even separately. And besides, the words below imply that the IMR, of course, should have worked in conditions acceptable for tanks, and no more, but not in the conditions of the scattered insides of the reactor!

          Here, in the discussions, for some reason, they omit that the IMR was nevertheless created for the WAR. And the crew may have had to complete the task in battle - at the cost of their lives.
          How long does a tank live there in battle?
          Those. the barrier, in addition to radiation, could also be hit by enemy fire.
          In Chernobyl, the radiation in places literally nearby could differ, well, very much.
          And the task of the IMR crew in Chernobyl was still very different from this one, but as a result of the use of nuclear weapons

      In the next thread about the "dirty bomb" they wrote what is the difference between Chernobyl and a global nuclear war. In short: in a nuclear bomb there are 20-25 kg of fissile material, and a quarter burns out, well, plus induced radiation. In Chernobyl, 110-115 tons flew out of the reactor. Feel the difference. Well, the fact that working in conditions of radioactive contamination is only one of the functions, and has not been tested in practice.

      The main difference between a peaceful atom and a military atom is the duration of the contamination of the area.
      During a nuclear explosion, the radiation falls according to the rule "powers of 10 through powers of 7" - 10 times after 7 hours, 100 times after 49 hours, etc.
      For the contents of the reactor, this rule does not work - a peaceful atom is much longer-lived.
      So in Chernobyl, the IMR had to work in a situation "we are constantly being bombarded with SBCs."

    Subsequently, some IMR-2s went through a far from artisanal refinement, which made it possible to raise the level of protection to a factor of 1 times less radiation.

    This is not a handicraft, but a factory modification - IMR-2D, nicknamed the "dinosaur" developed by the Research and Design Institute of Mounting Technology (NIKIMT).
    ... the engine was protected by filters from radioactive dust getting inside, a gamma locator, a manipulator for collecting radioactive materials in a special collection, a grab that could remove soil up to 100 mm thick, special radiation-resistant television systems, a tank periscope, an operator's life support system were installed and the driver, equipment for measuring the radioactive background inside and outside the car. IMR-2D was covered with a special, well-deactivated paint. The machine was controlled by a television screen. It took 20 tons of lead to protect against radiation. Protection throughout the entire internal volume of the machine in real conditions was about 2 thousand times, and in some places reached 20 thousand times.

    Here is a review of the machine from an end user:
    The car has changed a lot. We must start with the fact that there were no windows on it at all. Instead, there are three television cameras and two monitors (one for the operator, the other for the mechanic). The view was provided to the driver by one camera (to the right of the hatch), two to the operator (one on the boom, the second on the boom head). The camera of the driver and the one on the boom had rotation drives. The one on the head looked at the manipulator, turned with it and looked like a cylinder about half a meter long and 20 centimeters in diameter. A gamma locator was installed next to it. But the manipulator .... I don’t know who and what the developers said, but the grapple that they put on the first “dinosaur” could be used somewhere on the Moon or a gold mine, but it was clearly small for our cases. Its volume, God forbid, was 10 liters! True, and it was used quite poorly. Since the most active materials, as a rule, did not have a large volume, and the gamma locator made it possible to identify them very accurately. Another feature of the first two IMR-2Ds was the lack of bulldozer equipment (the second one copied the first one, but differed from it in a normal grab, it arrived in two weeks). All had a very powerful air filtration system (a kind of hump on the blinds based on an air filter from the T-80). The most important feature was enhanced anti-radiation protection. And it's different at different levels. On the bottom 15000 times, on the hatches (both) 500 times, on the chest levels of the driver - 5000 times, etc. The mass of cars reached 57 tons. The third one (came already in July) differed from the two previous ones by the presence of windows (two pieces, forward and left-forward, completely indecent, 7 centimeters thick, which made them look like embrasures of a pillbox) near the driver. The operator still had cameras and a monitor.

    I do not agree with the statement that the accident at the Chernobyl nuclear power plant is the largest, in Fukushima things are much worse. Here is the fact that the USSR threw unprecedented resources to eliminate the accident, yes.

    That is, where the WRI will pass, the rest of the armored vehicles will go there. There is no reason to protect the IMR from radiation much better than tanks are protected from the same radiation.

    And I think there is. WRI in the focus works, and the other BT passes at maximum speed. That is, the exposure time is a couple of orders of magnitude longer.

    Minor remarks. So the car did a good job!

    I read that on the basis of the IMR they made mastodons weighing up to 84 tons, poured lead and other materials, and achieved a reduction in radiation up to 15000 times, that's just how many of them were made.

    when designing the anti-nuclear protection of the IMR-2, the greatest attention was paid to the lower parts of the hull and the bottom, since the radiation should have come from the soil contaminated with a nuclear explosion.
    Amazing. That is, someone decided that these machines will work in a bare field, on which there is nothing. No forest and its debris, no ruins, no equipment irradiated by the explosion, no dust.
    How is this to be understood? What exactly were these machines supposed to do and where? On a patch of fused soil, in the very epicenter? What a mystery.
