UK nuclear site pleads guilty to IT security breaches from 2019 to 2023
The UK’s most hazardous nuclear site, Sellafield, has pleaded guilty to criminal charges related to cybersecurity failings brought by the industry regulator.
Lawyers acting for Sellafield told Westminster magistrates’ court on Thursday that cybersecurity requirements were “not sufficiently adhered to for a period” at the vast nuclear waste dump in Cumbria.
The charges relate to information technology security offences spanning a four-year period from 2019 to 2023. It emerged in March that the Office for Nuclear Regulation (ONR) intended to prosecute Sellafield for technology security offences.
Late last year the Guardian’s Nuclear Leaks investigation revealed a catalogue of IT failings at the site dating back several years.
Sellafield pleaded guilty to a charge that it had failed to “ensure that there was adequate protection of sensitive nuclear information on its information technology network”, the Financial Times reported.

“All the evidence shows that nuclear power is too slow to build, too expensive, and it remains highly polluting and dangerous,” one activist said.
An international coalition of environmental groups dropped banners and blockaded roads to protest the International Nuclear Energy Summit in Brussels on Thursday.
While the summit, hosted by the Belgian government and the International Atomic Energy Agency (IAEA), pushes nuclear energy as a replacement for fossil fuels, more than 600 climate action groups launched a declaration calling nuclear power plants a “distraction which slows down the energy transition.”
“We are in a climate emergency, so time is precious, and the governments here today are wasting it with nuclear energy fairy tales,” Greenpeace E.U. senior campaigner Lorelei Limousin said in a statement. “All the evidence shows that nuclear power is too slow to build, too expensive, and it remains highly polluting and dangerous.”
“The nuclear lobby camouflages itself beneath a climate-friendly facade, hoping to divert massive sums of money away from real climate solutions, at the expense of people and the planet.”
At the United Nations COP28 climate conference in the United Arab Emirates last year, more than 20 countries pledged to triple nuclear energy capacity by 2050. However, Greenpeace France calculated that achieving this would mean finishing 70 reactors each year between 2040 and 2050. This would be an unprecedented buildout in defiance of current trends: Between 2020 and 2023, 21 reactors were completed while 24 were shut down worldwide.
In the European Union specifically, many countries turned away from nuclear after 2011 in response to the Fukushima accident in Japan, according to Reuters. Germany shuttered its last three reactors for good in April 2023 following a successful anti-nuclear campaign there. In general, the nuclear share of the E.U. power mix dropped from 32.8% in 2000 to 22.8% in 2023, Greenpeace said.
Activists argue that nuclear still poses all the dangers the anti-nuclear movement has been warning about for decades and also cannot be ramped up quickly enough to prevent escalating climate extremes.
To reinforce this message, members of Greenpeace France blockaded the main roads to the Brussels summit using cars and bicycles. They also lit pink flares and threw pink powder as a motorcade of officials en route to the summit approached. The action succeeded in delaying the arrival of several delegations, Greenpeace E.U. said.
Other demonstrators dropped banners from the summit site at Brussels Expo reading, “Nuclear Fairy Tale,” while a group representing the 600 declaration signatories protested in front of an inflatable bouncy castle holding up a sign reading, “Nuclear fairy tales = climate crisis.”
The declaration was drafted by Climate Action Network Europe and signed by groups from at least 56 different countries and territories including Climate Action Network Canada, the David Suzuki Foundation, the Sierra Club, Food and Water Watch, CodePink, International Physicians for the Prevention of Nuclear War, and several 350.org, Fridays for Future, and Friends of the Earth affiliates.
“The nuclear lobby camouflages itself beneath a climate-friendly facade, hoping to divert massive sums of money away from real climate solutions, at the expense of people and the planet,” the declaration reads.
The signatories pointed out that, while the world must dramatically reduce greenhouse gas emissions by 2030 in order to limit global temperature rise to 1.5°C above preindustrial levels, it would take longer than this for any new nuclear plant to come online.
At the same time, it costs significantly more money to increase nuclear capacity than renewable options like wind and solar, they stressed. A new reactor requires almost four times the funds of a new wind power installation.
“Governments need to invest in proven climate solutions, such as home insulation, public transport, and renewable energy, rather than expensive experiments, like small modular reactors, which have no guarantees of actually delivering,” the declaration says.
It also points to safety risks across the nuclear lifecycle, from uranium mining to waste storage. And it adds that those dangers would only increase as temperatures rise.
“The climate crisis also increases the risks involved in nuclear power, as increased heatwaves, droughts, storms, and flooding all pose significant threats to the plants themselves and to the systems that aim to prevent nuclear accidents,” the signatories argued.
Instead, the declaration proposes that governments focus on achieving 100% renewable energy while also improving efficiency.
“What we demand is a just transition toward a safe, renewable, and affordable energy system that secures jobs and protects life on our planet,” the declaration concludes.

A new report says melting ice sheets and rising seas could disturb waste from U.S. nuclear projects in Greenland and the Marshall Islands.
Ariana Tibon was in college at the University of Hawaiʻi in 2017 when she saw the photo online: a black-and-white picture of a man holding a baby. The caption said: “Nelson Anjain getting his baby monitored on March 2, 1954, by an AEC RadSafe team member on Rongelap two days after ʻBravo.’”
Tibon had never seen the man before. But she recognized the name as her great-grandfather’s. At the time, he was living on Rongelap in the Marshall Islands when the U.S. conducted Castle Bravo, the largest of 67 nuclear weapon tests there during the Cold War. The tests displaced and sickened Indigenous people, poisoned fish, upended traditional food practices, and caused cancers and other negative health repercussions that continue to reverberate today.
A federal report by the Government Accountability Office published last month examines what’s left of that nuclear contamination, not only in the Pacific but also in Greenland and Spain. The authors conclude that climate change could disturb nuclear waste left in Greenland and the Marshall Islands. “Rising sea levels could spread contamination in RMI, and conflicting risk assessments cause residents to distrust radiological information from the U.S. Department of Energy,” the report says.

Britain’s public spending watchdog has launched an investigation into risks and costs at Sellafield, the UK’s biggest nuclear waste dump.
The National Audit Office (NAO), which scrutinises the use of public funds, has announced it will examine whether the Cumbria site is managing and prioritising the risks and hazards of the site effectively as well as deploying resources appropriately and continuing to improve its project management.
The findings of its investigation are expected to be published this autumn.
Sellafield is Europe’s most toxic nuclear site and also one of the UK’s most expensive infrastructure projects, with the NAO estimating it could cost £84bn to maintain the site into the next century.
Predictions of the ultimate bill for the site, which holds about 85% of the UK’s nuclear waste, vary. It cost £2.5bn to run the site last year, and the government estimates it could ultimately take £263bn to manage the country’s ageing nuclear sites, of which Sellafield accounts for the largest portion.
The UK’s most hazardous nuclear site, Sellafield, has been hacked into by cyber groups … the Guardian can reveal.
The astonishing disclosure and its potential effects have been consistently covered up by senior staff at the vast nuclear waste and decommissioning site, the investigation has found.
The Guardian has discovered that the authorities do not know exactly when the IT systems were first compromised. But sources said breaches were first detected as far back as 2015, when experts realised sleeper malware – software that can lurk and be used to spy or attack systems – had been embedded in Sellafield’s computer networks.
…
The full extent of any data loss and any ongoing risks to systems was made harder to quantify by Sellafield’s failure to alert nuclear regulators for several years, sources said.
The revelations have emerged in Nuclear Leaks, a year-long Guardian investigation into cyber hacking, radioactive contamination and toxic workplace culture at Sellafield.
The site has the largest store of plutonium on the planet and is a sprawling rubbish dump for nuclear waste from weapons programmes and decades of atomic power generation.
…
In one highly embarrassing incident last July, login details and passwords for secure IT systems were inadvertently broadcast on national TV by the BBC One nature series Countryfile, after crews were invited into the secure site for a piece on rural communities and the nuclear industry.
