A dose of between 4.5 and six is considered deadly. This is a huge but cramped place: 13,000 people work in a 6 sq km pen surrounded by razor wire. Material housed here will remain radioactive for 100,000 years. Second: Sellafield has turned the Irish Sea and its seabed into a nuclear dump. A recent investigation by the BBC found a catalogue of safety concerns including insufficient staffing numbers to operate safely and an allegation that radioactive materials were stored in degrading plastic bottles. ", Updated 19/09/16, 16:00 - References to certain building names have been removed at the request of Sellafield. Though the inside is highly radioactive, the shielding means you can walk right up to the boxes. Safely decommissioning a 1950s nuclear waste storage facility Known as one of the four most hazardous buildings in Western Europe, the Sellafield Pile Fuel Cladding Silo (PFCS) was commissioned in 1952 to safely store radioactive cladding – pieces of metal tubes used for uranium fuel rods in some of the UK’s earliest nuclear reactors. AWE Management’s plan for their holdings of nuclear waste was developed during 2012 and 2013 as a ‘do minimum’ option to compare against other proposed courses of action. But it failed to expose the full scandal of the UK's 'reprocessing' of spent fuel into 140 tonnes of plutonium, enough to build 20,000 nuclear bombs - while leaving £100s of billions of maintenance and cleanup costs to … Thorp was closed for two years as a result of the leak, costing tens of millions of pounds in lost revenue. Structures that will eventually be dismantled piece-by-piece look close to collapse – but they can’t fall down. Sellafield’s isolated location, perched on the Cumbrian coast looking over to the Isle of Man, is also a slow death-warrant; the salty, corrosive sea air plays a lethal game of cat and mouse with the site’s ageing infrastructure. Sellafield site ranks as one of Europe's largest industrial complexes, managing more radioactive waste in one place than any other nuclear facility in the world. Sellafield is the largest nuclear site in Europe and the most complicated nuclear site in the world. Each month, we’ll bring you hundreds of the latest roles from across the industry. Walk inside and your voice echoes, bouncing off a two-storey tall steel door that blocks entry to the core. The remaining waste is mixed with glass and heated to 1,200°C. 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. WIRED was not given access to these facilities, but Sellafield asserts they are constantly monitored and in a better condition than previously. It’s a warm August afternoon and I’m standing on a grassy scrap of land squinting at the most dangerous industrial building in western Europe. “The air inside is so contaminated that in minutes you’d be over your total dose for the year,” Davey says of one room currently being decommissioned. The highly radioactive fuel is then transferred next door into an even bigger pool where it’s stored and cooled for between three and five years. Sellafield Ltd is responsible on behalf of the Nuclear Decommissioning Authority for cleaning-up the country’s highest nuclear risks and hazards to safeguarding nuclear fuel, materials and waste. The flask is then removed, washed, cleaned and tested before being returned to the sender. Sellafield is the largest nuclear site in Europe and the most complicated nuclear site in the world. The National Physical Laboratory (NPL) has deployed its High Accuracy Inspection System (HAIS) to the Sellafield nuclear site in Cumbria. The leak was eventually contained and the liquid returned to primary storage. The solution, for now, is vitrification. Some buildings are so dangerous that their collapse could be catastrophic, but the funding, expertise or equipment needed to bring them down safely isn’t immediately available. "Nobody yet has come up with a different suggestion other than sticking it in the ground,” Davey tells me, half-jokingly. As we clean up the site, much is still unknown. The site currently handles nearly all the radioactive waste generated by the UK’s 15 operational nuclear reactors. 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. Instead of bumbling, British, gung ho pioneers, Sellafield is now run by corporate PR folk and slick American businessmen. An operator uses the arm to sort and pack contaminated materials into 500-litre plastic drums, a form of interim storage. They are both now investigating where the waste came from, as is Sepa. 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. Safely disposing of nuclear waste is an expensive business. In other areas of Sellafield, the levels of radiation are so extreme that no humans can ever enter. "It's so political that science doesn't matter. The reality is that a small percentage of the nuclear waste generated at Sellafield is liquid. In one image a seagull can be seen bobbing on the water. The WIRED conversation illuminates how technology is changing every aspect of our lives—from culture to business, science to design. 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. The facility, which opened in 1994, is due to close permanently in 2018. Sellafield nuclear waste site to close due to coronavirus, Magnox reprocessing plant will begin controlled shutdown after 8% of staff self-isolate,Guardian Jillian Ambrose Energy correspondentThu 19 Mar 2020 Britain’s nuclear waste site will shut its reprocessing plant at Sellafield after more than 8% of its staff began self-isolating to prevent the spread of the … The leaked liquid was estimated to contain 20 metric tons of uranium and 160kg of plutonium. As well as being filled with waste during the early years of the nuclear age, Sellafield’s ponds were also overwhelmed with spent fuel during the 1974 miners’ strike. Sellafield is an important part of the NDA group, working collaboratively with others in the group to deliver our part of the NDA mission. Seagulls chatter, the hum of machinery is constant, a pipe zig-zagging across the ground vents steam. This burial plan is the government’s agreed solution but public and political opposition, combined with difficulties in finding a site, have seen proposals stall. Our Sellafield, Decommissioning, Fuel and Waste (SDFW) team is responsible for the regulation of 20 nuclear licensed sites including Sellafield, all GB decommissioning sites, fuel cycle facilities, waste management facilities and nuclear research sites. As of August 2020 , activities at the site include nuclear fuel reprocessing, nuclear waste storage and nuclear decommissioning, and it is a former nuclear power generating site. Last night's BBC Panorama programme did a good job at lifting the lid on Britain's ongoing nuclear disaster that is Sellafield, writes Ian Fairlie. Each two-metre square box weighs up to 50 tonnes and contains around 100 sieverts of radiation. Sellafield, the largest nuclear site in Western Europe, reprocesses spent nuclear fuel, splitting it into plutonium, uranium and waste. On April 20, 2005 Sellafield workers found a huge leak at Thorp, which first started in July 2004. Registered in England No. It is now home to a one-tonne BROKK-90 demolition machine which smashes up sections of the lab and loads them into plastic buckets on a conveyer belt. … Sellafield monitors nuclear waste with NPL technique 18th May 2021 12:02 am 17th May 2021 12:30 pm The National Physical Laboratory (NPL) has deployed its High Accuracy Inspection System (HAIS) to the Sellafield nuclear site in Cumbria. Sellafield is now completely controlled by the government-run Nuclear Decommissioning Authority. 11569365, Study calls for new air quality regulations in buildings, Upbeat Barometer points to growth for SME manufacturers, Opinion: Lessons learnt from the semiconductor shortage, NUS team harvests WiFi signals to power electronics, Smart bandage designed to detect infection, CETEC project to commercialise recycled wind turbine materials. This giant storage pool is the size of two football fields, eight metres deep and kept at a constant 20°C. The Windscale gas-cooled reactor took nine years to decommission. The outside of the container is decontaminated before it is moved to Sellafield’s huge vitrified product store, an air-cooled facility currently home to 6,000 containers. This was where, in the early 1950s, the Windscale facility produced the Plutonium-239 that would be used in the UK’s first nuclear bomb. This glass is placed into a waste container and welded shut. For official figures and essential information about how the data has been produced, always refer to the UKRWI 2019 published reports. The buckets are then fed through an enclosed hole in the wall to a waiting RAPTOR master-slave robot arm encased in a box made of steel and 12mm reinforced glass. Sellafield is the largest nuclear site in Europe and, with over 1000 nuclear … As of 2014 the First Generation Magnox Storage Pond contained 1,200 cubic metres of radioactive sludge. It is one of several hugely necessary, and hugely complex, clean-up jobs that must be undertaken at Sellafield. When records couldn’t be found, Sellafield staff conducted interviews with former employees. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. But working out exactly what is in each laboratory has proven complicated. Inspection of the waste stores is vital for safe storage, but the process is time-consuming. Not everything at Sellafield is so seemingly clean and simple. Standing in a tiny control room crammed with screens and a control desk, Davey points to a grainy video feed on a CRT monitor. In March 2015 work began to pump 1,500 cubic metres of radioactive sludge from the First Generation Magnox Storage Pond, enough to fill seven double-decker buses. All comments are moderated. And the waste keeps piling up. The facility has an 8,000 container capacity. nuclear waste legacy storage ponds at the Sellafield nuclear reprocessing site in Cumbria, UK. This tick-tock noise, emitted by Tannoys dotted throughout the facility, is the equivalent of an 'everything's okay' alarm.
