With winter approaching, the team is working to a tight deadline. Transcript. VIKTOR IVKIN (Survivor, worked at the reactor, was there the night of disaster): (Translation) By this time, I had already vomited a couple of times, and if a person shows this reflex, that means they've absorbed over 100 roentgens. NARRATOR: They will build the first half of the arch from the top down, using jacks mounted on towers to raise it, in a series of massive lifts. ELENA OBI (commissioning engineer at Novarka): Yes, we can lift. Windfall Films, part of Argonon, has been commissioned to produce a 60-minute unique access special, Inside Chernobyl’s Mega Tomb, for BBC Four. They operate the panels remotely from a platform on one side of the arch. NARRATOR: The telescopic tube was out, so the team went back to the drawing board. ROB OWEN: The weight of the telescopic tube just kept growing and growing; it would just be outrageous. The Chernobyl disaster of 1986 resulted in a radioactive fallout which was 100 times greater than a nuclear bomb. Inside the jacks, hydraulic jaws grip the wires attached to the crane and slowly hoist them up. Thirty years on as scientists investigate the true impact of the disaster the shell of the nuclear reactor is collapsing. NARRATOR: The closer they get to the reactor, the more difficult the operation becomes. It has taken 18 years of planning, seven years of construction, and a unique international collaboration of 10,000 men and women from 30 countries, but three decades after the world's worst nuclear accident, Chernobyl is finally sealed away, for generations to come. Bigger than Wembley Stadium and taller than the Statue of Liberty, it will seal in the entire disaster site for 100 years. We do know that a zone of deadly radiation has been released. If successful, this special crane will be deployed alongside conventional cranes to dismantle the damaged reactor. Documentary which follows the construction of a trailblazing 36,000-tonne steel structure to entomb the ruins of the nuclear power plant destroyed in the 1986 Chernobyl disaster. The New Safe Confinement, the structure… This site uses Akismet to reduce spam. DAVID DRISCOLL (Health and Safety Manager): We provide everybody with dosimeters. JEAN-PHILIPPE GARDEUR (Deputy Construction Manager): Everything we touch, everything we do is completely crazy. This documentary examines the crimes of David Parker Ray (November 6, 1939 – May 28, 2002), who was charged with kidnapping, raping and torturing women in a small New Mexico town. Inside Chernobyl’s Mega Tomb joins a captivating roster of programming from the BAFTA and Emmy award-winning Windfall Films. 6.50 Children of Chernobyl. But, aside from the absence of people and a few warning signs, there is little indication that large amounts of radioactive material fell on this land. The various bits of the aircraft carriers being assembled in Rosyth were skidded into place, albeit over shorter distances, in dry dock. Left uncovered, it would continually release radioactive dust into the air, a poisonous cloud to threaten the surrounding area. Next, they will slide the two halves of the arch together to make one enormous structure. So, engineers have equipped the arch with tilting panels, like giant cat doors, that they must raise and then lower into place when the arch is in position, sealing the small remaining gap with an extra-durable plastic membrane. Thirty workers died, 50,000 people fled the nearest city and radioactive fallout turned an area larger than Lancashire in the United Kingdom into a no go zone. I am also thinking of myself. In 1986, in the heart of Ukraine, the Chernobyl nuclear reactor exploded, releasing 400 times more radiation than the Hiroshima Bomb. We are under pressure. These move a pair of wedges that grip the steel rail. A mega dome tasked to entomb the crumbling remains of the Chernobyl nuclear reactor. Everything's ready? NARRATOR: The pads are made of P.T.F.E., the polymer used on non-stick cookware. Over the next six months, workers braved extreme radiation to seal the reactor inside a 300,000-ton shelter, made from steel and concrete. Remediation efforts inside the NSC will include the use of the NIST-designed RoboCrane technology. The configuration of the wires is crucial. We know that it's way beyond its design life. To make sure they don't twist the arch, lasers measure the exact position of both sides and display any difference on screens in the control room. Like other areas inside the zone, it will remain uninhabitable for hundreds of years. NARRATOR: Six years after the sarcophagus was built, the Ukrainian government held a competition for ideas for a new containment structure, to make the Chernobyl reactor safe. A large earthquake here would be felt in Chernobyl. Advertisement Original funding for this program was provided by Cancer Treatment Centers of America, 23andMe, The David H. Koch Fund for Science, and the Corporation for Public Broadcasting. They told us that if we were exposed to the level of 10 roentgens, we would be honorably discharged. Then, in the future, the remotely-controlled robot cranes inside the arch will dismantle the old sarcophagus and remove the remains to a yet-to-be-built storage facility. And it took approximately 10 years to decide which idea would be the best, which idea can be constructed. Before they slide it over the reactor, engineers must transform it into a machine designed to deal with Chernobyl's radioactive debris. With funding tight, he wants to have the shelter in place as soon as possible, so he needs to know firsthand the condition of the sarcophagus. They will mount them on two concrete runways that extend alongside the crumbling sarcophagus. IAN CARLING: The biggest problem we have is the weather. It remains the world's worst-ever nuclear power plant disaster. Please note that all guests must bring a form of identification and may be subject to a random bag search. IAN CARLING: This cladding, it's stainless steel, and it is designed for the purpose of containing any airborne contaminated particles from escaping into the environment, during the dismantling of the reactor Number 4. But the site is still too radioactive for builders to construct a new cover directly over the old reactor. ROB OWEN: We kind of had to really go back and study the design. When the plant exploded it blew a hole in the roof and radiation came vomiting out, making the area one of the most deadly places on earth. We remember the place as clean, beautiful and bright. DAVID DRISCOLL: There's a lot more activity, because we now have many more tasks to complete, all in the same period. For the plan to work, Ian Carling must ensure the interior ceiling is completely sealed. Everything we touch, everything we do, is completely crazy. Related Documentaries. NEWS CLIP, VOICE OF MAN DIRECTING "LIQUIDATORS”: Akuratno, Akuratno. We don't have small things. NARRATOR: But just as the arch approaches the reactor, they run into trouble. from fluid pictures PRO . The Soviet authorities declared a 19-mile-radius exclusion zone around the reactor. A 60-minute version of the film, produced by Windfall Films (part of Argonon) for BBC Four in association with NOVA/WGBH, PBS Distribution, and France Television, NHK and … China is building airstrips in the South China Sea on disp. But parts of the old sarcophagus stick out, which would prevent the arch from sliding to its final position. After seven days of pushing, the arch is finally in position over the reactor. And it also had to carry a tremendous payload at the end. They bulldozed and buried the most contaminated homes, along with over a million tons of contaminated soil. We see quite a range of animals on most of the cameras that we bring back in: red deer, wolves, lynx, Eurasian lynx, and, also, European bison, as well. BAPTISTE BRIOIS: It's coming closer and closer. However, 30 years later, the sarcophagus is crumbling, and another disaster at Chernobyl looms. In the following weeks, 28 workers died from acute radiation sickness. Inside Chernobyl’s Mega Tomb will air on Wednesday 21st December, 9pm, on BBC Four. NARRATOR: For the engineers, this is the last chance to make sure everything works. In Ukraine's harsh climate, that's a daunting challenge. Eighty, ninety people will be involved. Before engineers slide the arch over the reactor, they must install them and the carriage that will carry the robotic arm. But if the weight on the platform is heavy enough, all the wires will stay tight, and the platform will remain rigid enough to hold the robot arm that will dismantle the sarcophagus. To this day nobody really kn... What happens to nature after a nuclear accident? reading of the location of the camera, and then we can use handheld G.P.S., like this, to be able to find the cameras again, and then come and see what it's recorded. NICOLAS CAILLE: This is a one-off skidding. None of this must escape, but the sarcophagus enclosing this material, is falling apart. MIKE WOOD: So, we can see that we've got an elk here and wild boar, as well. It was called a Tensile Truss. This indiscriminate targetin, The threat of China is becoming big news, the media is beating the drums of war as the world is being primed to regard China as a new enemy. NARRATOR: Today, inside the old sarcophagus, 95 percent of the uranium that was in the reactor before the explosion lies scattered and exposed. It will take a long time. NARRATOR: The winning plan, from the French construction consortium Novarka, is very ambitious. Today in Ukraine an international team of engineers is racing to assemble one of the most complex super structures ever built, at an extraordinary 36,000 tones it will be the largest structure moved on land. 1.0k votes, 73 comments. It will be the largest structure ever moved on land. Everyone in position? But we will see. They are very efficient. NARRATOR: Over 40 countries, including the United States, have contributed a total of $1.5-billion to build the new shelter and finally close a chapter on a disaster that occurred on April 26th, 1986. But the team can't afford to relax. In mid February 2013, the Cecil hotel of Los Angeles received complaints of a peculiar dark tinge to the hotels drinking water. NICOLAS CAILLE: You have a lift of 30 meters, and then you build below, and the structure is going up, up, up, up, up. This is the inside story of the race to build Chernobyl’s Mega Tomb. MIKE WOOD: When we put the cameras out, we take a G.P.S. 17.3m members in the Documentaries community. Despite the weather, the engineers must press on. The right half of this building contains the reactor that exploded. GUILLAUME MOREL: Nothing, everything should be fine. The workers have just 11 days to prepare to move the arch. Now, they must bolt on the steel tubes that will form the sides of the structure. Building it this way enables the construction crew to keep a safe distance from the destroyed reactor, where the radioactive materials left inside present the most danger to the workers. IAN CARLING (Cladding Site Engineer): It is extremely dangerous. Baptiste Briois is the engineer in charge. I saw a documentary a few years ago, I think it was posted on Reddit, and I think it was fan-made but I'm not sure. GEERT-JAN THIJSSEN (Mammoet): Over these nooks, we put the Teflon pad. Inside the ceiling of the arch, they will attach two giant robotic cranes. NARRATOR: To drill into walls or pull a beam, the robotic arm must be able to push and pull horizontally. Two miles from the reactor lies the abandoned city of Pripyat. NARRATOR: Rob is testing a quarter-scale model of the remote-controlled crane that will be installed inside the new shelter. The waves would strike with unstopp... For the last 50 years the world has lived in fear of radiation. Learn how your comment data is processed. About 300 yards away from the reactor, where radiation levels are low enough for builders to work safely, they will construct two halves of a giant steel arch, 30 stories high. tl;dw. Building Chernobyl’s Mega Tomb follows the team of international engineers as they race against time to build the structure over the disaster site. NICOLAS CAILLE: It will be a complicated task. On one, they will attach a giant telescopic tube equipped with a robotic arm. NARRATOR: One remaining job is crucial before they slide the arch, opening its enormous special doors. Once they have built the first half of the arch, they will slide it to one side of the worksite to make enough space to construct the second half. NICOLAS CAILLE: Now, we are almost at the end. The Secret Life of Scientists and Engineers. It will be the largest structure ever moved across land. New documentaries straight to your inbox. When the cranes dismantle the old reactor, they will throw up clouds of radioactive dust. Thirty years later, its hastily built enclosure is crumbling. Home › Off Topic Inside Chernobyl's Mega Tomb. Winter temperatures here can plunge to minus-20 degrees Fahrenheit. It took two weeks in … The threat of China is becoming big news, the media is beating the drums of war as the world is being primed to regard China as a new enemy. It becomes snagged on a barbed wire fence. Every year, we're becoming fewer and fewer. The gap between the arch's exterior roof and interior ceiling will be sealed, creating a vast enclosed space around the steelwork. We have to remove the sarcophagus built by the Russians. It's not being totally demolished, they can't do that for obvious reasons as there are still some areas which are highly dangerous. WHEN: Thursday, 9 February, 17:15 - 20:30 WHERE: One Exchange Square, London EC2A 2JN Admission: Admission is free but registration is required. Hastily, a "sarcophagus" was built to contain the radioactive materials that lingered at the site after the explosion. Phim Inside Chernobyls Mega Tomb 2016 phụ đề tiếng việt | Phimne3.com Your email address will not be published. On that day, technicians were carrying out a new test on this Soviet-built, water-cooled nuclear reactor. Thirty years on, ecologist Mike Wood is investigating what types of animals live in the zone and if the levels of radiation affect where they live. So, we have to tilt it before, and then we can restart to the end and finish it tonight. SIMON EVANS: This equipment monitors the stability of the existing shelter, which is absolutely essential to ensure that we know exactly what is going on here. Phim Inside Chernobyls Mega Tomb 2016 HD Vietsub Thuyết minh. The extreme radiation prevented the workers from completing the welds needed to seal the prefabricated sections of the sarcophagus together. Inside Chernobyl's Mega Tomb - BBC4. Building Chernobyl's MegaTomb. NARRATOR: Mike is setting up camera traps in three different areas, places with high, medium and low radioactive contamination. NICOLAS CAILLE: It's a feeling of pride. We have some junctions here, so, because of this gap, we have to do a compressed sealant, which makes the air seal tight. NARRATOR: But just as the crane lifts off, they hit a glitch. So, we can still finish today. In 1985 Los Angeles would be terrorized by a series of brutal sexual assaults and murders. Seven, eight, five millimeters. As the gamma rays leave the reactor, they get further apart from each other, and some are absorbed in the air. NARRATOR: One hundred roentgens is over 900 times the maximum amount of radiation considered safe to receive over an entire year. Inside Chernobyl’s Mega Tomb will air on Wednesday 21 st December, 9pm, on BBC Four. Spasibo. NARRATOR: No one has attempted to dismantle an exploded nuclear reactor before. So, once the arch will have reached its final location, the radiation conditions do not allow a manned operation at that location. So, you can understand that if you are going further from the reactor, the dose rates are lower. I have the French national dosimeter; I have a Ukrainian national dosimeter; and then we also have an electronic dosimeter that is our operational dosimeter. (Translation) "Good. Trying to make connections with people who are in different ways living on the, The Great Wall of China, it's been studied for decades but now new technology is revealing its secrets like never before. Just as the team is raising the heaviest panel, a blizzard strikes. NICOLAS CAILLE: They received, probably, 200 different ideas. I think they preserve these just for occasional visitors. Here, close to the sarcophagus, the high number of gamma rays makes it too dangerous to work for the long periods of time needed to construct the arch. Inside Chernobyl’s Mega Tomb. NICOLAS GUILCHER (Radiation Protection Engineer at Novarka): You can see, here, the reactor Number 4, which was damaged in ‘86, and at about 200 meters from the reactor, the platform where the arch will be built. Every year, on the anniversary of the disaster, the people of Slavutych, the town where most Chernobyl workers now live, remember those who lost their lives. This would allow them to pull the structure apart piece by piece, load the debris into sealed trucks and take the radioactive waste to storage. IAN CARLING: Today, we had the wind problem. In this National Geographic special we see archaeologist Allan Maca, an exper, Black Wednesday occurred on 16 September 1992, it was a day that saw the British government faced one of the biggest financial crisis in history, it was a day when the Bank of England lost billi, In 1985 Los Angeles would be terrorized by a series of brutal sexual assaults and murders. 1 The New Safe Confinement (NSC) was designed to prevent further radiation leaks from Ukraine's stricken Chernobyl nuclear power plant. This is the inside story of the race to build Chernobyl’s Mega Tomb. Stream Inside Chernobyl's Mega Tomb free online. But the engineers have one thing on their side. After all this time, mankind’s worst nuclear disaster is still so dangerous that the world has to complete an international mega-project just to keep it safe. These give off so much radiation, that it shows up as white flashes on video. Extreme Engineering - Inside Chernobyl's Mega Tomb. In the surrounding area, they washed down surfaces to remove the radioactive dust. People described how it had a funny taste and a strange odour. Some of these, pass through the reactor walls and stream out into the surrounding space. NICOLAS CAILLE: It must last 100 years. Inside the damaged reactor building, Simon's team wears masks to protect them from inhaling radioactive dust. Certainly, it would release another major release of radiation into the environment. DAVID DRISCOLL: We're coming to the end. You get so much data you have to act correctly and quickly. To prevent another deadly catastrophe, engineers will entomb it inside a completely new shelter. Powerful pumps will then extend the pistons, to push the arch forward. It will be the final step in the long operation to seal the reactor away and make the site safe. ROB OWEN (Crane System Manager): It is just fantastic, really, really an amazing structure. We have a lot of watchmen, because our clearance is very limited. Although Chernobyl isn't in a seismic area, it is only 400 miles from the Vrancea zone in Romania, one of the most active seismic areas in Europe. GEERT-JAN THIJSSEN: That's the difficult part. In time, like any building, the arch would eventually collapse, and a future generation would need to build another, even bigger structure to keep the reactor safe. As Building Chernobyl’s Mega Tomb explains, the trouble with replacing the Sarcophagus is, unsurprisingly, radiation. NARRATOR: Success. NARRATOR: The team relies on 13 hydraulic jacks, fixed near the top of the arch, to lift the 900-ton crane into position. The dangers are very real. Episode guide, trailer, review, preview, cast list and where to stream it on demand, on catch up and download. Executive Producer is Windfall Films’ Creative Director, Carlo Massarella. They are heading to Chernobyl, in North Central Ukraine, once part of the Soviet Union. NARRATOR: In the vicinity of the reactor, the radioactive fallout forced a third-of-a-million people to evacuate, never to return. In spring, 2012, workers start to assemble the steel tubing that will form the giant skeleton of the arch. Now, they are building a facility here for storing radioactive fuel and waste from the reactors at Chernobyl and from other plants in Ukraine. The most dangerous are gamma rays. And then, after, they will have to break the concrete. VOICE MAN #1 IN CONTROL ROOM: We have the confirmation that we are ready. Would it work here? There is still a lot of the radiation in organic stuff but as long as you are not drinking the water or eating an apple off a tree you are fine. The doc will air on BBC4 this month and in spring 2017 on PBS in the US. The arch is so heavy, that it would overload the wheel bearings, which would fracture, leaving the structure stranded. If the platform was supported by vertical wires, it would swing, but using three pairs of wires arranged in triangles and adding a heavy weight makes it rigid. So, first of all, it is to remove the roof over the exploded reactor. It would shake the heavy tube, generating extreme forces that could damage the arch. It simply stood on the ruins of the destroyed reactor. NIKOLAI STEINBERG (Former Chief Engineer, Chernobyl Nuclear Power Plant): They had no time. It's crumbling. In Minnesota, Rob Owen leads the team designing the dismantling system. NARRATOR: It takes four hours to winch the massive "cat door" open. To solve this problem, they're engineering the steel to be inside a special climate-controlled environment. سال انتشار: ۲۰۱۶. NICOLAS CAILLE: We have to provide tools to enable the deconstruction. Required fields are marked *. Thanks.". The metallic structure cannot last 100 years. NARRATOR: In 1986, in what was the Soviet Republic of Ukraine, the Chernobyl nuclear reactor exploded, releasing 400 times more radioactive material than the Hiroshima Bomb. NARRATOR: Painting the steel arch protects it for a time, but, eventually, the paint will degrade, exposing the metal to moisture in the air, causing it to rust. ROB OWEN: The fuel that was there is still there, but when they start to dismantle the sarcophagus, you're going to expose that fuel. The ducts will constantly recirculate the dry air to make sure that the atmosphere in the enclosure remains dry, so the steelwork doesn't rust. ROB OWEN: We have the six wire ropes and a lot of weight here, as you can see, on the bottom. Episodes. NARRATOR: Each jack has enough power to lift over two loaded jumbo jets. SIMON EVANS (Chernobyl Shelter Fund): These are the world's most uncomfortable boots. IAN CARLING: This job, it's extremely dangerous: the winds, the rains. NICOLAS CAILLE: It will hit the chimney. Two-thousand tons of force pushes against the arch. It talked about the disaster, but also about the whole situation before the accident, and how the power plant was a marvel of technology at the time, and how good it was to live in Pripyat because it had a lot of ammenities that the average soviet city didn't have at all. BAPTISTE BRIOIS: It was very quick. NARRATOR: Now engineers can start tests on the full-scale crane. It uses an ingenious system of wires to carry a platform holding a robotic arm. They drafted 350,000 people to clean up the radioactive fallout. They must partially lower one of the tilting panels. It's crucial that the pistons move both sides of the arch at the same speed. Now, an international team of engineers is racing the clock to assemble one of the most ambitious superstructures ever built—an extraordinary 40,000 ton, $1.5 billion dome to encase the crumbling remains of the Chernobyl nuclear reactor.
