This is what creates a Type II supernova: the core-collapse of an ultra-massive star. Anywhere downwind of Sellafield during the releases would be rendered uninhabitable probably for generations and people caught in the fall-out would have a greatly increased chance of getting . Management, profligate with money, was criminally careless with safety and ecology. In other areas of Sellafield, the levels of radiation are so extreme that no humans can ever enter. They told me I had a lung burden and that was an accumulation from the 30-odd years I'd worked at Sellafield. You see the little arm at the end of it? Cassidy said. The building is so dangerous that it has been fitted with an alarm that sounds constantly to let everyone know they are safe. They just dropped through, and you heard nothing. It thought nothing of trying to block Wastwater lake to get more water or trying to mine the national park for a waste dump. Then they were skinned of their cladding and dissolved in boiling nitric acid. Its an existential threat to link-in-bio companies. It might not have a home yet, but the countrys first geological disposal facility will be vast: surface buildings are expected to cover 1km sq and underground tunnels will stretch for up to 20 km sq. So in a couple of thousand years the Earth and the Solar System would be enveloped in hot, highly ionized gas. ", Updated 19/09/16, 16:00 - References to certain building names have been removed at the request of Sellafield, Inside Sellafield: how the UK's most dangerous nuclear site is cleaning up its act, Sellafield is home to 80% of the UK's nuclear waste and some of the world's most hazardous buildings. "It's so political that science doesn't matter. This facility houses 21 steel tanks and associated equipment in above ground concrete cells. A terrorist attack on Sellafield could render the north of England uninhabitable and release 100 times the radioactivity produced by the nuclear accident at Chernobyl in 1986, the House of Commons defence committee was told yesterday. The government built 26 such reactors across the country. Not far from the silos, I met John Cassidy, who has helped manage one of Sellafields waste storage ponds for more than three decades so long that a colleague called him the Oracle. What would happen if Sellafield exploded? It also reprocesses spent fuel from nuclear power plants overseas, mainly in Europe and Japan 50,000 tonnes of fuel has been reprocessed on the site to date. Six years ago, the snakes creators put it to work in a demo at Sellafield. What would happen if Sellafield exploded? He was right, but only in theory. You see, an explosion usually inflicts damage in two major ways . Read about our approach to external linking. It says something for how Britain's nuclear establishment worked from the start that when Windscale No1 Pile caught fire in October 1957, it was hushed up so well that even with 11 tons of uranium ablaze for three days, the reactor close to collapse and radioactive material spreading across the Lake District, the people who worked there were expected to keep quiet and carry on making plutonium for the bomb. Thirty-four workers were contaminated, and the building was promptly closed down. It took two years and 5m to develop this instrument. The day I visited Sellafield was the UKs hottest ever. Video, 00:01:03, Up Next. The UKs plans are at an earlier stage. "I often think there will have been a Seascale cluster of leukaemia because that's where the fallout from the big chimneys was closest. It is one of several hugely necessary, and hugely complex, clean-up jobs that must be undertaken at Sellafield. Jeremy Hunt wants nuclear power classed as sustainable: is it? What would happen if Sellafield exploded? Its anatomy is made up of accordion folds, so it can stretch and compress on command. But then the pieces were left in the cell. These have to be secure and robust but they cant be irretrievably secure and robust, because scientists may yet develop better ways to deal with waste. This year, though, governments felt the pressure to redo their sums when sanctions on Russia abruptly choked off supplies of oil and gas. Video, 00:00:35, Drone captures moment lost child is found, Watch: Massive flames rise from Crimea oil tank. What would happen if Sellafield exploded? Responding to the accusations, Sellafield said there was no question it was safe. It all put me in mind of a man whod made a house of ice in deepest winter but now senses spring around the corner, and must move his furniture out before it all melts and collapses around him. But at Sellafield, with all its caches of radioactivity, the thought of catastrophe is so ever-present that you feel your surroundings with a heightened keenness. The decommissioning programme is laden with assumptions and best guesses, Bowman told me. Anywhere else, this state of temporariness might induce a mood of lax detachment, like a transit lounge to a frequent flyer. Both buildings, for the most part, remain standing to this day. How high will the sea rise? Endoscopes are poked through lead-clad walls before robotic demolition machines and master-slave arms are installed to break up and safely store the waste. An emergency could occur following a fire, explosion, seismic event or serious leak in one of the areas handling radioactive materials at the Sellafield Site. In some cases, the process of decommissioning and storing nuclear waste is counterintuitively simple, if laborious. An operator uses the arm to sort and pack contaminated materials into 500-litre plastic drums, a form of interim storage. It feels like the most manmade place in the world. Inside the most dangerous parts of Sellafield. What would happen if Sellafield exploded? In 1983, a Sellafield pipeline discharged half a tonne of radioactive solvent into the sea. Perhaps, the study suggested, the leukaemia had an undetected, infectious cause. Each two-metre square box weighs up to 50 tonnes and contains around 100 sieverts of radiation. In a reactor, hundreds of rods of fresh uranium fuel slide into a pile of graphite blocks. The source of the leak, as America soon learned, was traced to a tiny rubber part called an O-ring, which formed the seal . Union leader and ex-Commando Cyril McManus says he thought the fire might mean the workers got a day off; Wally Eldred, the scientist who went on to be head of laboratories at BNFL, says he was told to "carry on as normal"; and chemist Marjorie Higham says she paid no attention. . Video, 00:00:28, Armed heist at Paris luxury jewellery store in daylight, Watch: Flames engulf key bank in Sudan's capital. The outside of the container is decontaminated before it is moved to Sellafields huge vitrified product store, an air-cooled facility currently home to 6,000 containers. This burial plan is the governments agreed solution but public and political opposition, combined with difficulties in finding a site, have seen proposals stall. Terrorists could try to get at the nuclear material. Its anatomy is made up of accordion folds, so it can stretch and compress on command. Theres currently enough high and intermediate level radioactive waste to fill 27 Olympic-sized swimming pools. Depending on the direction of the wind, cities like Newcastle, Edinburgh and Leeds would be well within fallout range, as would be Dublin. One retired worker, who now lives in nearby Seascale, thought there might be a dropped fuel rod in one of the glove boxes a rumour that turned out to be false. These atoms decay, throwing off particles and energy over years or millennia until they become lighter and more stable. Walk inside and your voice echoes, bouncing off a two-storey tall steel door that blocks entry to the core. Correction: we mixed up the Sun's lifespan with its age. NDA is a non-departmental public body sponsored by the Department for Business, Energy and Industrial Strategy, and publishes a tax strategy for the NDA Group in accordance . Still, it has lasted almost the entirety of the atomic age, witnessing both its earliest follies and its continuing confusions. From an operational nuclear facility, Sellafield turned into a full-time storage depot but an uncanny, precarious one, filled with toxic nuclear waste that has to be kept contained at any cost. Now I look back and think, no, we caused that," says McManus. What emerges is the intimate, honest, sometimes ugly story of how a wartime bomb factory was dumped in one of Britain's most cut-off areas, turned to producing plutonium for the atom bomb, then nuclear electricity and is now a American-led multinational corporation decommissioning the mess that it largely created. The tanks contain high level radioactive waste in the form of self heating, acidic liquid that requries continuous cooling and agitation.". One moment youre passing cows drowsing in pastures, with the sea winking just beyond. This has been corrected. A later report found a design error caused the leak, which was allowed to continue undetected due to a complacent culture at the facility. The room on the screens is littered with rubbish and smashed up bits of equipment. As a result, Bowman admitted, Sellafields scientists are having to invent, mid-marathon, the process of winding the site down and theyre finding that they still dont know enough about it. Then it is vitrified: mixed with three parts glass beads and a little sugar, until it turns into a hot block of dirty-brown glass. A 2,000-mile high pillar of cloud has formed on Saturn and scientists believe the planet may explode in the near future. A terrorist attack on Sellafield could render the north of England uninhabitable and release 100 times the radioactivity produced by the nuclear accident at Chernobyl in 1986, the House of. After a brief, initial flash, Betelgeuse will brighten tremendously . Two floors above, a young Sellafield employee sat in a gaming chair, working at a laptop with a joystick. As the nation's priorities shifted,. Working 10-hour days, four days a week in air-fed suits, staff are tasked with cleaning every speck of dust and dirt until the room has been fully decontaminated. Now it needs to clean-up Sellafield houses more than 1,000 nuclear facilities on its six. The very day before I visited Sellafield, in mid-July, the reprocessing came to an end as well. Conditions inside the Shear Cave are intense: all operations are carried out remotely using robots, with the waste producing 280 sieverts of radiation per hour - more than 60 times the deadly dose. The area includes as far south as Walney, east as Bowness and north almost to the Scottish border. As of 2014 the First Generation Magnox Storage Pond contained 1,200 cubic metres of radioactive sludge. Crab Supernova Explosion [1080p] Watch on. Three are in Cumbria, and if the GDF does wind up in this neighbourhood, the Sellafield enterprise would have come full circle. It was a historic occasion. So itll float down to the bottom of the pond, pick up a nuclear rod that has fallen out of a skip, and put it back into the skip. Sometimes, though, a human touch is required. Though the inside is highly radioactive, the shielding means you can walk right up to the boxes. Leaked images of the ponds from 2014 show them in an alarming state of disrepair, riddled with cracks and rust. For nearly 30 years, few people knew that the fire dispersed not just radioactive iodine but also polonium, far more deadly. Eventually, the plant will be taller than Westminster Abbey and as part of the decommissioning process, this structure too will be torn down once it has finished its task, decades from now. A government agency, Nuclear Waste Services, is studying locations and talking to the people living there, but already the ballpark expenditure is staggering. Like so much else in B204, the vat was radioactive waste. Their further degradation is a sure thing. The government continues to seek volunteers for what would be one of the most challenging engineering projects ever undertaken in the UK. The nuclear industry certainly knew about the utility of water, steel and concrete as shields against radioactivity, and by the 1970s, the US government had begun considering burying reactor waste in a GDF. These are our favorite classic flicks, Marvel movies, and Star Wars sagas on the streaming platform. Watch. The flasks were cast from single ingots of stainless steel, their walls a third of a metre thick. That forecast has aged poorly. Video, 00:00:33, Watch: Flames engulf key bank in Sudan's capital, Drone captures moment lost child is found. Eventually there will be two more retrieval machines in the silos, their arms poking and clasping like the megafauna cousins of those fairground soft-toy grabbers. In 1956 this stretch of Cumbrian coast witnessed Queen Elizabeth II opening Calder Hall, the worlds first commercial nuclear power station. I was a non-desirable person on site.". Is Sellafield worse than Chernobyl? Since 1991, stainless steel containers full of vitrified waste, each as tall as a human, have been stacked 10-high in a warehouse. Once cooled, it forms a solid block of glass. Video, 00:00:35Drone captures moment lost child is found, Watch: Massive flames rise from Crimea oil tank. On the other hand, high-level waste the byproduct of reprocessing is so radioactive that its containers will give off heat for thousands of years. Workers at Sellafield, reporting their alarming radiation exposure to their managers, were persuaded that theyd walk [it] off on the way home, the Daily Mirror reported at the time. On the one hand, it calls for ingenious machines like the laser snake, conceived especially for Sellafield. A moment of use, centuries of quarantine: radiation tends to twist time all out of proportion. A government study concluded that radiation from Sellafield wasnt to blame. About 9bn years ago, tens of thousands of giant stars ran out of fuel, collapsed upon themselves, and then exploded. Near Sellafield, radioactive iodine found its way into the grass of the meadows where dairy cows grazed, so that samples of milk taken in the weeks after the fire showed 10 times the permissible level. NASA . The waste comes in on rails. And so they must be maintained and kept standing. So much had to be considered, Mustonen said. This winter, Sellafield will hire professional divers from the US. The silos are rudimentary concrete bins, built for waste to be tipped in, but for no other kind of access. A B&Q humidity meter sits on the wall of the near-dark warehouse, installed when the boxes were first moved here to check if humidity would be an issue for storage. Sellafield, formerly a Royal Ordnance Factory, began producing plutonium in 1947. All of Sellafield is in a holding pattern, trying to keep waste safe until it can be consigned to the ultimate strongroom: the geological disposal facility (GDF), bored hundreds of metres into the Earths rock, a project that could cost another 53bn. It was just bonkers," says Alan Postlethwaite, the truculentvicar of Seascale, who was accused of being a crypto-communist for even thinking the plant might be linked to cancers. Many of the earliest structures here, said Dan Bowman, the head of operations at one of Sellafields two waste storage ponds, werent even built with decommissioning in mind. After its fat, six-metre-long body slinks out of its cage-like housing, it can rear up in serpentine fashion, as if scanning its surroundings for prey. Governments change, companies fold, money runs out. That would contaminate fisheries and travel north on currents, making fishing in western Scotland impossible. Theres no fuel coming in. I dont think its really hit the team just yet.. Its a major project, Turner said, like the Chunnel or the Olympics.. An anonymous whistleblower who used to be a senior manager at Sellafield told the broadcasters Panorama programme that he worried about the safety of the site every day. Nothing is produced at Sellafield any more. What would happen if Sellafield exploded? A super-massive black hole couldn't explode. Video, 00:00:28Armed heist at Paris luxury jewellery store in daylight, Watch: Flames engulf key bank in Sudan's capital. Most of it was swarf the cladding skinned off fuel rods, broken into chunks three or four inches long. Sellafield took its present name only in 1981, in part to erase the old name, Windscale, and the associated memories of the fire. All radioactivity is a search for stability. What looked like a smart line of business back in the 1950s has now turned out to be anything but. When all else had failed to stop the fire, Tuohy, a chemist, now dead, scaled the reactor building, took a full blast of the radiation and stared into the blaze below. Dr Thompson said: "A civilian nuclear facility is a potential radiological weapon if the facility contains a large amount of radioactive material that can be released into the environment. Once in action, the snake took mere minutes to cut up the vat. The problem is that the plant which is supposed to turn this liquid waste into more managable and less dangerous glass blocks has never worked properly and a backlog cannot be cleared for another 15 years. This glass is placed into a waste container and welded shut. A 10-storey building called B204 had been Sellafields first reprocessing facility, but in 1973, a rogue chemical reaction filled the premises with radioactive gas. Some buildings are so dangerous that their collapse could be catastrophic, but the funding, expertise or equipment needed to bring them down safely isnt immediately available. Every day 10,000 litres of demineralised water is pumped in to keep the pool clean. Compared to the longevity of nuclear waste, Sellafield has only been around for roughly the span of a single lunch break within a human life. A terrorist attack on Sellafield could render the north of England uninhabitable and release 100 times the radioactivity produced by the nuclear accident at Chernobyl in 1986, the House of Commons defence committee was told yesterday. The future is rosy. The snakes face is the size and shape of a small dinner plate, with a mouth through which it fires a fierce, purple shaft of light. Sellafields waste comes in different forms and potencies. At one point, when we were walking through the site, a member of the Sellafield team pointed out three different waste storage facilities within a 500-metre radius. In January 2012 Cumbria County Council rejected an application to carry out detailed geological surveys in boroughs near Sellafield. A pipe on the outside of a building had cracked, and staff had planted 10ft-tall sheets of lead into the ground around it to shield people from the radiation. The missiles with proximity fuses generally detonate when they come within a certain distance of their target. More than 140 tonnes of plutonium are stored in giant. Armed heist at Paris luxury jewellery store in daylight. The process will cost at least 121bn. The less you know about it the less you can tell anyone else.". (modern). But some folk could laugh it off. (The cause was human error: someone had added a wheat-based cat litter into the drum instead of bentonite.) Anywhere downwind of Sellafield during the releases would be rendered uninhabitable probably for generations and people caught in the fall-out would have a greatly increased chance of getting . Until then, Bowman and others will bend their ingenuity to a seemingly self-contradictory exercise: dismantling Sellafield while keeping it from falling apart along the way. During the 1957 reactor fire at Sellafield, a radioactive plume of particles poured from the top of a 400-foot chimney. Those who were working there didn't want to be seen against the thing," says Mary Johnson, now in her 90s, who was bornon the farm that was compulsorily purchased to become the site of Sellafield. On one floor, we stopped to look at a remotely operated vehicle, or ROV a steamer trunk-sized thing with a yellow carapace, floating in the algal-green water.
