The number of radioactive atoms in the kind of iodine found in nuclear waste byproducts halves every 16m years. In comparison, consider how different the world looked a mere 7,000 years ago, when a determined pedestrian could set out from the Humber estuary, in northern England, and walk across to the Netherlands and then to Norway. Planning for the disposal of high-level waste has to take into account the drift of continents and the next ice age. 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. Every second, on each of the plant’s four floors, I heard a beep – a regular pulse, reminding everyone that nothing is amiss. “We’ve 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.
A government study concluded that radiation from Sellafield wasn’t to blame. Perhaps, the study suggested, the leukaemia had an undetected, infectious cause. Our vision is to accelerate the development of AI applications and we do this by providing high-quality training data to AI companies. We also do work in other areas such as image recognition, categorization, and transcription. But MPF vehicles are not exactly miniature versions of M1 Abrams main battle tanks, George said via email.

The US allocated $6bn to save struggling plants; the UK pressed ahead with plans for Sizewell C, a nuclear power station to be built in Suffolk. Japan, its Fukushima trauma just a decade old, announced that it will commission new plants. Even as Sellafield is cleaning up after the first round of nuclear enthusiasm, another is getting under way. The river system has changed dramatically over time, as dams were built, irrigation and development increased and the use of flood plains changed. The water flowing into South Australia is the highest it's been in decades, with river levels now above the floods of 1974 in some places. While Australians may be familiar with the cyclical nature of droughts and floods, Bill Johnson says human made impacts combined with climate change are causing them to become more extreme.
At the moment, Nuclear Waste Services is in discussions with four communities about the potential to host a GDF. Three are in Cumbria, and if the GDF does wind up in this neighbourhood, the Sellafield enterprise would have come full circle. After the 2011 disaster at the Fukushima nuclear plant in Japan, several countries began shuttering their reactors and tearing up plans for new ones. They’d become inordinately expensive to build and maintain, in any case, especially compared to solar and wind installations. In the UK, the fraction of electricity generated by nuclear plants has slid steadily downwards, from 25% in the 1990s to 16% in 2020. Of the five nuclear stations still producing power, only one will run beyond 2028.

I only ever saw a dummy of a spent fuel rod; the real thing would have been a metre long, weighed 10-12kg, and, when it emerged from a reactor, run to temperatures of 2,800C, half as hot as the surface of the sun. In a reactor, hundreds of rods of fresh uranium fuel slide into a pile of graphite blocks. Then a stream of neutrons, usually emitted by an even more radioactive metal such as californium, is directed into the pile. Those neutrons generate more neutrons out of uranium atoms, which generate still more neutrons out of other uranium atoms, and so on, the whole process begetting vast quantities of heat that can turn water into steam and drive turbines. Strauss was, like many others, held captive by one measure of time and unable to truly fathom another. The short-termism of policymaking neglected any plans that had to be made for the abominably lengthy, costly life of radioactive waste.
As the water arrives, parched, barren land is transformed into oases teeming with life. In Australia, the line between drought and flood feels like it can change in the blink of an eye. Ome industrial machines have soothing names; the laser snake is not one of them. 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. Its anatomy is made up of accordion folds, so it can stretch and compress on command. The snake’s face is the size and shape of a small dinner plate, with a mouth through which it fires a fierce, purple shaft of light.

"I think that it's a fundamental problem in terms of policy, we have to have some buffers here. Most of all, to manage these rivers so that we can provide for human health, but also for the environment. For a long time, traditional owners up and down the basin say they've been excluded from government policies and contemporary water management. River ecologist Richard Kingsford has watched the Murray-Darling Basin through droughts and floods, surveying the system from the land and sky.
He spent his childhood travelling and camping along the river system, following his father who worked on the railways. "It seems a bit of a mismatch between what the flow forecasts are saying and what we're seeing on ground," says Chrissie Bloss, manager of water delivery in the South Australian Department for Environment and Water. "The determination is made by the amount of resource available. If we're in a drying sequence, then people who own water licences don't have the water allocated to them, it's as simple as that. Hall doesn't rely on irrigation water because he grazes cattle on the marshlands. "Burrendong Dam would have made it easy through the '17–20 drought if they hadn't allocated all the water to general security licence." Leanne recognises the pain of communities and neighbours upstream impacted by flooding and says it's a privilege to be on the marshes during this boom.

If Onkalo begins operating on schedule, in 2025, it will be the world’s first GDF for spent fuel and high-level reactor waste – 6,500 tonnes of the stuff, all from Finnish nuclear stations. The species that is building it, Homo sapiens, has only been around for a third of that time.

As water from right across the basin makes its way into South Australia, the state is recording flow rates and river heights not seen in decades in some areas. Two floors above, a young Sellafield employee sat in a gaming chair, working at a laptop with a joystick. 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”. With a delicacy not ordinarily required of it, the toilet brush wiped debris and algae off a skip until the digits “9738”, painted in black, appeared on the skip’s flank. 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.
The spot where we stood on the road, he said, “is probably the most hazardous place in Europe”.

At 38 tons, MPF vehicles are designed to be light enough so that two can fit on an Air Force C-17 Globemaster transport aircraft.
