The countryside around is quiet, the roads deserted. Crab Supernova Explosion [1080p] Watch on. But the flask, a few scratches and dents aside, stayed intact. What are the odds of tsunamis and earthquakes? Once sufficiently cooled, the spent fuel is moved by canal to Sellafields Head End Shear Cave where it is chopped up, dropped into a basket and dissolved in nitric acid. If Philip K Dick designed your nightmares, the laser snake would haunt them. A moment of use, centuries of quarantine: radiation tends to twist time all out of proportion. However, the Ministry of Defence said yesterday that a "quick response" procedure was in place to cover the whole of the country in the event of a hijack attack. The invisibility of radiation and the opacity of governments make for a bad combination. Responding to worries about how robust these containers were, the government, in 1984, arranged to have a speeding train collide head-on with a flask. An operator uses the arm to sort and pack contaminated materials into 500-litre plastic drums, a form of interim storage. Sellafield says vitrification ensures safe medium-to-long-term storage, but even glass degrades over time. What would happen if Sellafield exploded? The sheer force of these supernova detonations mashed together the matter in the stars cores, turning lighter elements like iron into heavier ones like uranium. Sellafield nuclear site a 'toxic mix of bullying and harassment' Here's a look at the technology being used in the clean-up operation. The leaked liquid was estimated to contain 20 metric tons of uranium and 160kg of plutonium. Thorp was closed for two years as a result of the leak, costing tens of millions of pounds in lost revenue. 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. They dont know exactly what theyll find in the silos and ponds. ", 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. When I visited in October, the birches on Olkiluoto had turned to a hot blush. The building is so dangerous that it has been fitted with an alarm that sounds constantly to let everyone know they are safe. Video, 00:05:44, Ros Atkins breaks down the BBC chairman loan row, Schoolboy, 13, stops bus after driver passes out. The contingency planning that scientists do today the kind that wasnt done when the industry was in its infancy contends with yawning stretches of time. 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. Instead of bumbling, British, gung ho pioneers, Sellafield is now run by corporate PR folk and slick American businessmen. In January 2012 Cumbria County Council rejected an application to carry out detailed geological surveys in boroughs near Sellafield. Dixons father had been a welder here, and her husband is one of the firefighters stationed permanently on site. Nuclear fuel is radioactive, of course, but so is nuclear waste, and the only thing that can render such waste harmless is time. The air was pure Baltic brine. 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. Wealthy nations suddenly found themselves worrying about winter blackouts. The video is spectacular. Four decades on, not a single GDF has begun to operate anywhere in the world. Sellafields presence, at the end of a road on the Cumbrian coast, is almost hallucinatory. "It's all about the politics," Davey argues.
