He said these tanks contained 2,400 kilograms of caeisium-137, the main cause of off-site radiation exposure from the Chernobyl accident. Constructed by a firm named Posiva, Onkalo has been hewn into the island of Olkiluoto, a brief bridges length off Finlands south-west coast. 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. Dr Thompson's report, sent this week in response to the committee's call for new evidence following a report it published last month, is likely further to alarm the Irish government, which has repeatedly protested about danger from the high level waste tanks at Sellafield. The programme painted a negative picture of safety that we do not recognise, the statement continued. Lets go home, Dixon said. I still get lost sometimes here, said Sanna Mustonen, a geologist with Posiva, even after all these years. After Onkalo takes in all its waste, these caverns will be sealed up to the surface with bentonite, a kind of clay that absorbs water, and that is often found in cat litter. British Nuclear Fuels Limited, the government firm then running Sellafield, was fined 10,000. About 9bn years ago, tens of thousands of giant stars ran out of fuel, collapsed upon themselves, and then 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. 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. Nations dissolve. Among the sites cramped jumble of facilities are two 60-year-old ponds filled with hundreds of highly radioactive fuel rods. 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. It turned out that if you werent looking to make plutonium nukes to blow up cities, Magnox was a pretty inefficient way to light up homes and power factories.

Its 13,500 working parts together weigh 350 tonnes. The missiles with proximity fuses generally detonate when they come within a certain distance of their target. The GDF will effectively entomb not just decades of nuclear waste but also the decades-old idea that atomic energy will be both easy and cheap the very idea that drove the creation of Sellafield, where the worlds earliest nuclear aspirations began. Yellow circles denote full flasks, black are empty. Structures that will eventually be dismantled piece-by-piece look close to collapse but they cant fall down. If the alarm falls silent, it means the criticality alarm has stopped working.
