what happens if sellafield blows up

We sweltered even before we put on heavy boots and overalls to visit the reprocessing plant, where, until the previous day, technicians had culled uranium and plutonium out of spent fuel. At its heart is a giant pond full of radioactive . The programme painted a negative picture of safety that we do not recognise, the statement continued. THE Irish population is "a sitting duck" in the event of a nuclear accident at Sellafield, Green Party deputy leader, Mary White warned yesterday. The government is paying private companies 1.7bn a year to decommission ageing buildings at Sellafield. Below us, submerged in water, lay decades worth of intermediate-level waste not quite as radioactive as spent fuel rods, but more harmful than low-level paper towels. But Teller was glossing over the details, namely: the expense of keeping waste safe, the duration over which it has to be maintained, the accidents that could befall it, the fallout of those accidents. Prominence has been given to the use of iodine tablets as a means of limiting radiation dose. (That 121bn price tag may swell further.) Advice, based on knowledge of the radiation levels in a particular area, will be issued on local and national radio as to when it is most important to remain inside, and for how long. Hence the GDF: a terrestrial cavity to hold waste until its dangers have dried up and it becomes as benign as the surrounding rock. What happens when the battery is fully charged but still connected? When they arrived over the years, during the heyday of reprocessing, the skips were unloaded into pools so haphazardly that Sellafield is now having to build an underwater map of what is where, just to know best how to get it all out. Waste disposal is a completely solved problem, Edward Teller, the father of the hydrogen bomb, declared in 1979. With testing banned, countries have to rely on good maintenance and simulations to trust their weapons work. Feb 22, 2023. The snake, though, could slither right in through a hole drilled into a cell wall, and right up to a two-metre-high, double-walled steel vat once used to dissolve fuel in acid. That would create a mixture of magma, rocks, vapor, carbon dioxide and other gases. Material housed here will remain radioactive for 100,000 years. The flask is then removed, washed, cleaned and tested before being returned to the sender. A moment of use, centuries of quarantine: radiation tends to twist time all out of proportion. Video, At the crash site of 'no hope' - BBC reporter in Greece, Record numbers of guide dog volunteers after BBC story. 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. 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. 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. Every month one of 13 easy-to-access boxes is lifted onto a platform and inspected on all sides for signs of damage and leakage. Then a stream of neutrons, usually emitted by an even more radioactive metal such as californium, is directed into the pile. When the cloud does arrive, there will be no immediate physical ill effects to anybody. Theyd become inordinately expensive to build and maintain, in any case, especially compared to solar and wind installations. The disposal took place in two batches, with the first transferred from the laboratory to another location on the site and successfully and safely detonated at around 14:15 BST. Since it began operating in 1950, Sellafield has had different duties. Sellafield is home to 80% of the UK's nuclear waste and some of the world's most hazardous buildings. Environment Agency earlier said it was aware of the situation and was working with partners to monitor it. They just dropped through, and you heard nothing. He was manoeuvring an ROV fitted with a toilet brush a regular brush, bought at the store, he said, just kind of reinforced with a bit of plastic tube. Seagulls chatter, the hum of machinery is constant, a pipe zig-zagging across the ground vents steam. The government built 26 such reactors across the country. (That 121bn price tag may swell further.) Weve walked a short distance from the 'golf ball' to a cavernous hangar used to store the waste. Even this elaborate vitrification is insufficient in the long, long, long run. Once interred, the waste will be left alone for tens of thousands of years, while its radioactivity cools. It took two years and 5m to develop this instrument. At such a distance there is, of course, no possibility of any heat or blast effect, indeed no immediate effect of any kind. More dangerous still are the 20 tonnes of melted fuel inside a reactor that caught fire in 1957 and has been sealed off and left alone ever since. No one had figured out yet how to remove them. The estimated toll of cancer cases has been revised upwards continuously, from 33 to 200 to 240. A popular phrase in the nuclear waste industry goes: When in doubt, grout.) Even the paper towel needs a couple of hundred years to shed its radioactivity and become safe, though. Iodine tablets, however, are relevant only to circumstances where radioactive iodine is present and this is not always the case. Cassidys pond, which holds 14,000 cubic metres of water, resembles an extra-giant, extra-filthy lido planted in the middle of an industrial park. For nearly 30 years, few people knew that the fire dispersed not just radioactive iodine but also polonium, far more deadly. What's he waiting for? Waste can travel incognito, to fatal effect: radioactive atoms carried by the wind or water, entering living bodies, riddling them with cancer, ruining them inside out. Sellafields waste comes in different forms and potencies. That one there, thats the second most dangerous, says Andrew Cooney, technical manager at Sellafield, nodding in the direction of another innocuous-looking site on the vast complex. Overseas reprocessing contracts signed since 1976 require that this vitrified waste is returned to the country of origin, meaning Sellafield now only has responsibility for storing the UKs vitrified waste. This winter, Sellafield will hire professional divers from the US. 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. The towers of blocks are spaced to allow you to walk between them, but reach the end and youre in total darkness. Radioactive contamination was released into the environment, which it is now estimated caused around 240 cancers in the long term, with 100 to 240 of these being fatal. How dry is it below ground? Taryl and Elk Skins blow up a Krohler 25 hp engine then crack it ope. The lab operated in the 1970s and produced the Plutonium-238 used in early cardiac pacemakers and as a primary fuel source for Nasas deep space missions where solar energy isnt available. The waste comes in on rails. It is these two sites, known as First Generation Magnox Storage Pond and the Magnox Swarf Storage Silos, that are referred to as the most hazardous in Western Europe. At Sellafield, the rods were first cooled in ponds of water for between 90 and 250 days. At present the pool can hold 5.5 tonnes of advanced gas-cooled reactor (AGR) fuel, soon it will be able to hold 7.5 tonnes. This is Sellafields great quandary. The spot where we stood on the road, he said, is probably the most hazardous place in Europe. Train tracks criss-cross the ground as we pass Calder Hall and park up next to a featureless red and black building. It has its own railway station and, until September 11, 2001, its visitor centre was a major tourist attraction visited by an average of 1,000 people per day. It has been a dithery decade for nuclear policy. One moment you're passing cows drowsing in pastures, with the sea winking just beyond. Nations dissolve. In the waters gloom, cameras offer little help, he said: Youre mostly playing by feel. In the two preceding months, the team had pulled out enough waste to fill four skips. What would happen if the entire world launched nukes at the US at the same time? Sellafield said in a statement: "These chemicals are used extensively in many industries and are well understood. One of of the sites oldest buildings, constructed in the 1950s, carried out analytical chemistry and sampling of nuclear material. In Sellafield, these nuclear divers will put on radiation-proof wetsuits and tidy up the pond floor, reaching the places where robotic arms cannot go. Barrels containing high-level radioactive nuclear waste stored in a pool at Sellafield, in 2002. ike malign glitter, radioactivity gets everywhere, turning much of what it touches into nuclear waste. BT running the comms at Sellafield is infinitely more scary. Launches are confirmed and verified. "Nobody yet has come up with a different suggestion other than sticking it in the ground, Davey tells me, half-jokingly. Accidents had to be modelled. The radiation trackers clipped to our protective overalls let off soft cheeps, their frequency varying as radioactivity levels changed around us. Once in the facility, the lid bolts on the flasks are removed and the fuel is lowered into a small pool of water and taken out of the flask. It was on a charger and in the car with the hood up. Often we're fumbling in the dark to find out what's in there, he says. High-level waste, like the syrupy liquor formed during reprocessing, has to be cooled first, in giant tanks. 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. During this process, some of the uranium atoms, randomly but very usefully, absorb darting neutrons, yielding heavier atoms of plutonium: the stuff of nuclear weapons. Four decades on, not a single GDF has begun to operate anywhere in the world. It feels like the most manmade place in the world. Everybodys thinking: What do we do? So it was like: OK, thats it? The silos are rudimentary concrete bins, built for waste to be tipped in, but for no other kind of access. Workers Are Dying in the EV Industrys Tainted City. The UKs earliest reactors a type called Magnox were set up to harvest plutonium for bombs; the electricity was a happy byproduct. Sellafield currently costs the UK taxpayer 1.9 billion a year to run. However, using improper technique may cause problem. Even if a GDF receives its first deposit in the 2040s, the waste has to be delivered and put away with such exacting caution that it can be filled and closed only by the middle of the 22nd century. The Windscale fire of 10 October 1957 was the worst nuclear accident in the United Kingdom's history, and one of the worst in the world, ranked in severity at level 5 out of a possible 7 on the International Nuclear Event Scale. This glass is placed into a waste container and welded shut. At one spot, our trackers went mad. The rods went in late in the evening, after hours of technical hitches, so the moment itself was anticlimactic. At a conference in Drogheda at the weekend, BNFL invited the Radiological Protection Institute of Ireland to review the analysis, and we will be taking up this invitation without delay. The leaked liquid was estimated to contain 20 metric tons of uranium and 160kg of plutonium. In the UK, the fraction of electricity generated by nuclear plants has slid steadily downwards, from 25% in the 1990s to 16% in 2020. Some plastic drums are crushed into smaller pucks, placed into bigger drums and filled with grout. 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 1947, the Sellafield site opened with a single mission - the production of plutonium, a radioactive chemical element for use in Britain's nuclear deterrent. The laser can slice through inches-thick steel, sparks flaring from the spot where the beam blisters the metal. Sellafield hasnt suffered an accident of equivalent scale since the 1957 fire, but the niggling fear that some radioactivity is leaking out of the facility in some fashion has never entirely vanished. They dont know exactly what theyll find in the silos and ponds. Tellers complete solution is still a hypothesis. If they degrade too much, waste will seep out of them, poisoning the Cumbrian soil and water. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. But in the atoms of some elements like uranium or plutonium, protons and neutrons are crammed into their nuclei in ways that make them unsteady make them radioactive. Inside the most dangerous parts of Sellafield Remote submarines have explored and begun cleaning up old storage ponds. It posed no health risk, Sellafield determined, so it was still dripping liquid into the ground when I visited. A drive around the perimeter takes 40 minutes. But then the pieces were left in the cell. Weve got folks here who joined at 18 and have been here more than 40 years, working only in this building, said Lisa Dixon, an operations manager. 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. Scientists have uncovered the Roman recipe for self-repairing cementwhich could massively reduce the carbon footprint of the material today. fully-fuelled aircraft could directly impact on the highest-risk plants at the site without resulting in the release to the atmosphere of a very large quantity of radioactivity. Nuclear plants keep so much water on hand to cool fuel, moderate the reactors heat, or generate steam that a class of specialist divers works only in the ponds and tanks at these plants, inspecting and repairing them. This was where, in the early 1950s, the Windscale facility produced the Plutonium-239 that would be used in the UKs first nuclear bomb. We climbed a staircase in a building constructed over a small part of the pond. The huge risk of contamination means human exposure cant be risked. The radiation trackers clipped to our protective overalls let off soft cheeps, their frequency varying as radioactivity levels changed around us. British Nuclear Fuels Ltd now claims to have carried out an analysis which shows that such an attack would not necessarily have severe effects on Ireland. The flasks were cast from single ingots of stainless steel, their walls a third of a metre thick. Or how the site evolved from a farm to a nuclear icon and one of the biggest environmental clean-up challenges in Europe? The Magnox reprocessing area at Sellafield in 1986. aste disposal is a completely solved problem, Edward Teller, the father of the hydrogen bomb, declared in 1979. Nuclear fuel is radioactive, of course, but so is nuclear waste, and the only thing that can render such waste harmless is time. Dismantling Sellafield: the epic task of shutting down a nuclear site podcast, Hinkley Point: the dreadful deal behind the worlds most expensive power plant, Original reporting and incisive analysis, direct from the Guardian every morning, Dismantling Sellafield: the epic task of shutting down a nuclear site. "It is urgent that we clean up these ponds [but] it will be decades before they are . A popular phrase in the nuclear waste industry goes: When in doubt, grout.) Even the paper towel needs a couple of hundred years to shed its radioactivity and become safe, though. Structures that will eventually be dismantled piece-by-piece look close to collapse but they cant fall down. Theyre all being decommissioned now, or awaiting demolition. And it is intelligent. A glimpse of such an endeavour is available already, beneath Finland. Robots Enter the Race to Save Dying Coral Reefs. Hinkley Point C, the first new nuclear plant in a generation, is being built in Somerset, but its cost has bloated to more than 25bn. If the Yellowstone supervolcano were to erupt, it would happen like this: Heat rising from deep within the planet's core would begin to melt the molten rock just below the ground's surface. Sellafield has been called the most dangerous place in the UK, the most hazardous place in Europe and the world's riskiest nuclear waste site. In 1983, a Sellafield pipeline discharged half a tonne of radioactive solvent into the sea. Sellafield is so big it has its own bus service. Wealthy nations suddenly found themselves worrying about winter blackouts. It will be finished a century or so from now. Still, it has lasted almost the entirety of the atomic age, witnessing both its earliest follies and its continuing confusions. British Nuclear Fuels Limited, the government firm then running Sellafield, was fined 10,000. Once radiation arrives, the national network of radiation monitoring stations, supplemented by mobile monitoring units of the Defence Forces and Civil Defence, will enable movement of the radiation cloud to be tracked and radiation levels in each area to be quantified. Not everything at Sellafield is so seemingly clean and simple. "It's so political that science doesn't matter. In 2002 work began to make the site safe. It took two years and 5m to develop this instrument. I stood there for a while, transfixed by the sight of a building going up even as its demolition was already foretold, feeling the water-filled coolness of the fresh, metre-thick concrete walls, and trying to imagine the distant, dreamy future in which all of Sellafield would be returned to fields and meadows again. The day I visited Sellafield was the UKs hottest ever. In either case, a large volume of radioactive substances could rise into the atmosphere propelled by an explosion, a fire or both. Read about our approach to external linking. Responding to the accusations, Sellafield said there was no question it was safe. Britain's post war dreams of being a world leader in nuclear energy lie in radioactive ruins in Sellafield. If the alarm falls silent, it means the criticality alarm has stopped working. Thank you for calling the BT emergency radiation leak reporting centre. An area of the site was cordoned off for most of the day, and the canisters disposed of by controlled explosion. The leak caused 83 cubic metres of nitric acid solution to seep from a broken pipe into a secondary containment chamber - a stainless steel tub encased in two-metre-thick reinforced concrete with a capacity of 250 cubic metres. Questions 1, 2 and 3 are probably in my top 10 of most frequently asked questions. But Teller was glossing over the details, namely: the expense of keeping waste safe, the duration over which it has to be maintained, the accidents that could befall it, the fallout of those accidents. The threat, as stated above, is of airborne radioactivity and, even in the worst case, there will be a period of hours before it arrives. Sellafield's Magnox plant will stop reprocessing in July 2022 and enter a new era of clean-up and decommissioning. Other remote machines are being used to take cameras deep inside decaying. I kept being told, at Sellafield, that science is still trying to rectify the decisions made in undue haste three-quarters of a century ago. This year, though, governments felt the pressure to redo their sums when sanctions on Russia abruptly choked off supplies of oil and gas. Much of the facility is now being decommissioned. (Cement is an excellent shield against radiation. The main reason power companies and governments arent keener on nuclear power is not that activists are holding them back or that uranium is difficult to find, but that producing it safely is just proving too expensive. "Typical nuclear, we over-engineer everything, Edmondson says, taking out a dosimeter and sliding it nonchalantly along the face of one box. Beginning in 1956, spent rods came to Cumbria from plants across the UK, but also by sea from customers in Italy and Japan. He was right, but only in theory. The laser can slice through inches-thick steel, sparks flaring from the spot where the beam blisters the metal. The country has discovered enough lithium to electrify every vehicle on its roads, but the massive deposit has tensions running high. The government had to buy up milk from farmers living in 500 sq km around Sellafield and dump it in the Irish Sea. Now it needs to clean-up, No One Knows If Decades-Old Nukes Would Actually Work, Fat, Sugar, Salt Youve Been Thinking About Food All Wrong, 25 of the Best Amazon Prime Series Right Now, The Secret to Making Concrete That Lasts 1,000 Years. Terrorists could try to get at the nuclear material. In the water, the skips full of used fuel rods were sometimes stacked three deep, and when one was placed in or pulled out, rods tended to tumble out on to the floor of the pond. Anywhere else, this state of temporariness might induce a mood of lax detachment, like a transit lounge to a frequent flyer. Again, things are thrown out of balance, but this time, when the star collapses, it falls in on a core of volatile oxygen, rather than iron. The BBC is not responsible for the content of external sites. But the flask, a few scratches and dents aside, stayed intact. Environmental campaigners argue burying nuclear waste underground is a disaster waiting to happen. About 9bn years ago, tens of thousands of giant stars ran out of fuel, collapsed upon themselves, and then exploded. We must assume, however, that we might not be so lucky. You see the little arm at the end of it? Cassidy said. "That should help us remove more of the radioactivity early on, so that we can get on with the . Of the five nuclear stations still producing power, only one will run beyond 2028. There are more than 1,000 nuclear facilities. Laid out over six square kilometres, Sellafield is like a small town, with nearly a thousand buildings, its own roads and even a rail siding all owned by the government, and requiring security clearance to visit. It wasnt. The plant. Your call is important to us. 2023 BBC. Fill a water bottle one-third full of vinegar. Since December 2019, Dixon said, Ive only had 16 straight days of running the plant at any one time. Best to close it down to conduct repairs, clean the machines and take them apart. What will occur is exposure to radiation in the atmosphere, in rainfall, in food and in water, resulting in the risk of long-term health effects, most notably increased incidence of cancer in future years. Slide the funnel out of the balloon and have your child hold the portion of the balloon with the . The skips have held radioactive material for so long that they themselves count as waste. For most of the latter half of the 20th century, one of Sellafields chief tasks was reprocessing. It cannot be emphasised too strongly that there is the world of difference between being at, or very close to, the site of a major nuclear disaster and being 100 miles away, as the nearest point in this country is from Sellafield; or even 60 miles away as we are from Wylfa nuclear power station in north Wales, which is the nuclear installation nearest to Ireland.
