Atomexpo 2019, part 2: exposure

    The second story about the Atomexpo-2019 forum is dedicated to the exposition. In general, it can be divided into two parts - the large, advanced, beautiful and popular science space of Rosatom and the usual stands of the participants.

    Representatives of the world's atomic agencies opened the “Green Square” square in Sochi, this tree was supposed to be transplanted there after the forum ended.

    The slogan “The future is here” is felt right at the entrance. Being an enthusiast of monowheels, I could not help but photograph like-minded people.

    Rosatom presented its exposition in a separate room. The word “popular science” was used justly above, except for specific projects of the state corporation, a demonstration of the life cycle of nuclear fuel from production to disposal was organized, supplemented by interesting information. The center of the hall was given for an interactive installation, which changed the images on the screens, played good drone ambient and reacted to gestures. The artifact looked like a work of Cetagandan fiction artists Lois MacMaster Bujod (for those who did not read, this is a compliment, Cetagandan art is complex, high-tech and beautiful).

    The path of nuclear fuel began in a section with an IT specialist cutting the eye “Front End”.

    It looks like yellow cake - uranium concentrate U 3 O 8. Of course, an imitation is shown, but overall high realism is somewhat spoiled by an unstitched glove, due to which the “cake” is scattered outside.

    Authentic fuel assembly. Fuel pellets are prepared from uranium concentrate, which are loaded into fuel elements (fuel elements), which, in turn, are installed in such an assembly (fuel assembly).

    Cutout close up. “Tubules” are fuel rods, the black ones in them are fuel pellets (although they are proportionally higher than their width, ie cylinders).

    Section “Development and construction”. In general, the exhibition had a lot of interactive stands. Specifically, here it was possible to virtually assemble a floating nuclear power plant and look at the stage of construction of a conventional station.

    The interactive model clearly illustrated how complex and voluminous the NPP design is - as new stages move along the stages, new buildings are highlighted, and explanations are displayed on the screen.

    The next section, “Science and Innovation,” was dedicated to new projects. Here, for example, is the layout of the Shelf reactor , the main feature of which is the minimal need for maintenance (therefore, a human figure is more likely for scale). The capsule is sealed, so it can, for example, be loaded onto the seabed near a small town and controlled from a ground station. Once every ten years, the capsule is removed and maintained. Breakthrough Project

    Model- the BREST-OD-300 reactor will close the fuel cycle and, in addition to generating energy, will make it possible to extract from the spent nuclear fuel everything that can be useful, reducing the amount and activity of nuclear waste.

    Scheme of a closed nuclear cycle: turquoise on the left - power reactors, blue in the center - “BREST”, the process of processing and separation of spent nuclear fuel is shown at the top, green below is the waste.

    The “Engineering” section showed beautiful animated models of reactors with explanatory data.

    The most serious stand was in the “Generation” section. Now the NPP has simulators (the guide also called it a digital copy), which are used throughout the entire life cycle of the plant. At the design stage, you can see how and where it is better to place and show it to the customer. When the station is operating, personnel can be trained on the model in conditions as close as possible to the real situation, but without risk of damaging the real station with erroneous actions. Adequate physics, reflected in the model, makes it possible to arrange even simulation of accidents and gain experience without real risk and harm.

    Stand showing annealing of the reactor vessel. Under conditions of constant radiation exposure, the metal becomes brittle. And if the case is heated and very slowly cooled, then the initial properties of the metal will be restored, and the reactor will last another fifteen years.

    There was a lot of interesting things in the “New Businesses” sector. The big screen telling about the Northern Sea Route was guided by the real senior assistant of the Taimyr icebreaker. We talked a little bit. It is curious that now icebreakers do not need their own aviation for ice reconnaissance - fresh satellite photographs are available and much more convenient. Therefore, new icebreaker projects have a helipad, but there is no full-fledged hangar. A unusual noseexplained simply - the weight balance of the ship. The living quarters on the bow balance the machinery and equipment in the stern. “Lenin” had traditional proportions because it was an experimental ship, in the Taimyr class engineers defeated the designers and installed, in my opinion, ugly cubic superstructures, and in the Leader “engineers and designers managed to combine practical and aesthetic needs into a beautiful solution.

    Models of ionizing radiation sources that are used in instrumentation, agriculture, and medicine.

    New composite materials.

    Interesting displays, I have not figured out how they work. But it looks nice - the animation is superimposed on a three-dimensional image. And 3D printing technology is almost mainstream.

    A simple simulator of a smart city - we allocate resources for projects to improve infrastructure, we look at the result. It is impossible to lose, but, depending on the chosen projects, the benefits for the city will be different.

    VR - beautiful and clear.

    And finally, in the “Backend” the completion of operation. We are accustomed to the fact that the radioactive waste is green, liquid and luminous, but in reality only color matches.

    Nuclear waste is vitrified (bound to glass). After such an operation, the burial of waste underground becomes more likely a psychological gesture, because if the technology is followed, storing them on the surface will be just as safe.

    We pass to the stands of other participants. In general, two noticeably different groups can be distinguished - showing a flag and looking for business partners. The first group includes players already known to everyone, organizations close to Rosatom, and nuclear power plants. A distinctive feature of the stalls of the first group - there are at best paper leaflets. And finding facts interesting for the story is more difficult. In the most curious way, representatives of the Russian budgetary institution, seeing the badge “press” on me, refused to communicate in a trite way. The second group is trying to deliver the goods in person, so their kiosks are better designed, filled with exhibits, and it is more interesting to talk about them. Although there were some oddities here, the inhabitants of one kiosk, having seen that I was going to photograph it, immediately left their places, not wanting to get into the frame.

    Most of all, the company “Zeniternozemye” has spread out, having rolled out a promobot-barker. And she offers a fixed formwork made of concrete reinforced with metal fiber (“wire” in the bag below). It seemed to me, a person far from construction, that removable formwork should be economically more profitable, but, according to a company representative, they are not treated very carefully at construction sites. And the formwork they propose is done in ready-made blocks, quickly installed and has a plus for the nuclear industry in increased absorption of radiation. But for domestic construction it is still a little expensive.

    The uniqueness of the IUEC stand is that its customers are states. IUEC is an international center for uranium enrichment, and its goal is to ensure the supply of nuclear fuel. A participating country refuses an independent uranium enrichment project, thereby supporting a treaty on the non-proliferation of nuclear weapons, and in return receives access to nuclear fuel suitable only for nuclear power plants. So far, only Kazakhstan, Armenia and Ukraine are members of the organization, but who knows, maybe in the future new members will appear.

    Video surveillance systems for construction sites of the Techno-shield company. They say they are in demand for the case when the work is performed by a subcontractor.

    Greenatom is a subsidiary of Rosatom, therefore it belongs to the first category and shows the flag, but creatively. For a week, a program was written specially for the conference on Python + OpenCV that counts visitors and determines their mood, so that the kiosk looks more interesting. In addition, the company took networking to the developers forum for the sake of, and judging by the discussions that I noticed, the idea turned out to be successful.

    A silicon carbide startup was offering radioactive waste containers and furnace linings.

    Reactor model APR-1400 of the South Korean company KEPCO. The design, which began to be developed in 1992, has reached the point where it can be offered on the market - one unit is launched at home, two are tested, three are under construction. In addition, the construction of the Barak NPP, the first in the UAE, is underway.

    But the stand of the Chinese CNNC, on the contrary, caused a feeling of weak interest - fewer employees, a minimum of booklets and no souvenirs.

    A mobile unit for checking valves without removal from the Penza Valve Design and Technology Bureau.

    In general, many forum participating companies work not only with the nuclear industry, but also with the oil industry. Here, for example, EMIS flowmeters.

    Stand residents Skolkovo. It offered a variety of products - chemical precursors for nuclear medicine, tilt sensors of buildings (their products, by the way, are on the building where the forum was held), dosimetric systems, anticorrosion coatings, equipment for electrotomographic monitoring.

    For the average person, the nuclear industry is associated with the crack of a Geiger counter, but few dosimeters were presented - this is almost the only Atomtech stand.

    Titanium rose from the company VSMPO-AVISMA. Many have heard about its supply of titanium to aviation, but it is also used in the nuclear industry.

    Since we are talking about art, the Pipe Metallurgical Company distinguished itself here by introducing the Thinker from wire. In general, an excellent move, it was one of the most photographed objects of the forum.

    I express gratitude for the invitation to the press service of Rosatom and personally to Oleg Kondranenkov.

    The ending follows.
