Plutonium Disposition Strategy

Statement,
UK Parliament 24th Sept 2025, https://questions-statements.parliament.uk/written-statements/detail/2025-01-24/hcws388
The Department for Energy Security and Net Zero will work with the Nuclear Decommissioning Authority (NDA) to immobilise the UK-owned civil separated plutonium inventory at Sellafield.
Continued, indefinite, long-term storage leaves a burden of security risks and proliferation sensitivities for future generations to manage. It is the Government’s objective to put this material beyond reach, into a form which both reduces the long-term safety and security burden during storage and ensures it is suitable for disposal in a Geological Disposal Facility (GDF). Implementing a long-term solution for plutonium is essential to dealing with the UK’s nuclear legacy and leaving the environment safer for future generations.
Following a public consultation in 2011 the government at the time formed a preliminary policy view to pursue reuse of plutonium as mixed oxide fuel (MOX) but to remain open to any alternative proposals for plutonium management.
NDA have since carried out substantial technical, deliverability and economic analysis to identify a preferred option for a long-term disposition solution, including options for immobilisation and reuse. The outcome of this work recommended immobilisation as the preferred way forward to put the material beyond reach soonest and with greatest delivery confidence.
Following further development work the NDA will select a preferred technology for immobilisation of the plutonium as a product suitable for long-term storage and subsequently disposal in a GDF. Organisations involved in the delivery of this work will include the NDA, in particular Sellafield Ltd and Nuclear Waste Services, the UK National Nuclear Laboratory and the wider supply chain.
We expect that around the end of the decade following Government approval the NDA and Sellafield will begin delivery of the major build programme of plutonium disposition infrastructure. This programme is expected to support thousands of skilled jobs during the multidecade design, construction and operational period.
While work continues on long term immobilisation, the NDA is ensuring the continued safe and secure storage of plutonium in the UK. As part of this approach, new facilities are being built at Sellafield to repack the plutonium inventory for placement in a suite of modern stores.
Trump says he will approve power plants for AI through emergency declaration.

- President Donald Trump said he will expedite the construction of power plants for artificial intelligence through an emergency declaration.
- Trump said the plants can use whatever fuel they want, including coal.
President Donald Trump said Thursday he will expedite the construction of power plants for artificial intelligence through an emergency declaration, as the U.S. races against China for dominance in the industry.
“We’re going to build electric generating facilities. I’m going to get the approval under emergency declaration. I can get the approvals done myself without having to go through years of waiting,” Trump said in a virtual address to the World Economic Forum in Davos, Switzerland.
The plants can use whatever fuel they want, the president said, making clear that his administration won’t hold the AI industry to any climate targets.
There are some companies in the U.S. that have coal sitting right by the plant so that if there’s an emergency, they can go to that,” the president said.
Trump declared a national energy emergency on his first day in office, directing federal agencies to use whatever emergency authorities they have at their disposal to expedite energy infrastructure projects.
One day later, Trump unveiled a joint venture with OpenAI, Oracle and SoftBank to invest billions of dollars in AI infrastructure through a project called Stargate.
Power demand from artificial intelligence data centers is forecast to surge in coming years. The tech companies building the centers that support AI have primarily focused on procuring renewable energy, though they have shown a growing interest in nuclear power to meet their growing electricity needs.
While the tech sector has invested in carbon-free power to meet its climate goals, analysts believe natural gas will play a pivotal role in powering AI because it’s plentiful, is more reliable than renewables and can be deployed faster than nuclear.
Trump said he wants power plants to connect directly to data centers rather than supplying electricity through the grid.
“You don’t have to hook into the grid, which is old and could be taken out,” Trump said. This arrangement, called co-location, has faced opposition from some utilities, who are worried about losing fees and have warned that taking power off the grid could lead to supply shortages.
Wind, not nuclear, is the best way to meet Sweden’s climate goals, leading think tank says

By Reuters, January 24, 2025,
Reporting by Simon Johnson Editing by Frances Kerry
STOCKHOLM, Jan 23 (Reuters) – The cheapest way for Sweden to meet its expected rise in demand for electricity and goal of net zero emissions by 2045 is to build more onshore wind parks rather than increase the number of nuclear power plants, a leading think tank said on Thursday.
Sweden’s government has said it wants to build up to 10 new nuclear power plants by 2045 as transport and industry shift away from fossil fuels and demand for electricity is forecast to reach around 300 Terawatt hours (TWh) from 135 TWh in 2023.
The SNS think tank said that new nuclear power would be the most expensive solution, while more onshore wind and solar power combined with boosted production from hydropower plants and existing nuclear reactors would be able to meet increased demand without increasing Sweden’s low electricity prices.
“The high costs linked to nuclear power mean that these kinds of plants should primarily be built in countries with significantly higher electricity prices,” SNS said in a report on Sweden’s energy transition…………………………………………………………..
SNS said the government should focus on improving the electricity grid and regulatory framework to support private investment in new energy production. https://www.reuters.com/sustainability/wind-not-nuclear-is-best-way-meet-swedens-climate-goals-leading-think-tank-says-2025-01-23/
East Suffolk MP warned “billions worthlessly invested” in Sizewell C

Campaigners have written to Member of Parliament for Suffolk Coastal, Jenny
Riddell-Carpenter, about the billions spent on nuclear project Sizewell C,
after costs were speculated to end up spiralling to £40 billion.
The long-term expense of the project has come into question after it emerged
that spending on another nuclear power station that is being built by
French state-owned developer EDF is expected to be in excess of £40bn.
Cour des Comptes, the French state auditor, last week advised the energy
company to delay an investment decision on the nuclear power station in
Sizewell, after Hinkley Point C hit delays and refinancing difficulties.
It advised EDF to slash its financial exposure to the Hinkley Point C project
before making a final decision regarding its investment in Sizewell C.
Campaign group Together Against Sizewell C (TASC) said the auditor’s
advice “demonstrates there are external factors that are outside the
control of the UK government that mean the project might not be
completed”.

Hinkley Point C: EDF says fish issue could delay new plant operation
By Seth Dellow, Digital Reporter, Bridgwater Mercury 24th Jan 2025
EDF has stated that a “lengthy process” to identify acceptable compensation for the loss of fish stemming from Hinkley Point C could have “the potential to delay the operation of the power station.”
The French energy giant behind the nuclear project has welcomed government plans to stop delaying major infrastructure projects over ‘excessive’ environmental obligations.
The government is proposing to reduce the number of legal challenges a group can make in court, from three to just one attempt……………………………………………………….
EDF has warned that a “current lengthy process to identify and implement acceptable compensation for a small remaining assessed impact on fish has the potential to delay the operation of the power station.”
It follows the recent delay of a formal consultation over the proposed location of a new salt marsh, which would act as an environmental mitigation for the harm the project would bring to 44 tonnes of fish.
According to EDF, creating a salt marsh “is the only option currently likely to be accepted as a mitigation.” But local residents along the Severn, including landowners and farmers, have previously expressed their opposition to the plans. The initial proposal to create a saltmarsh at Pawlett Harms was opposed in Parliament, with Bridgwater’s MP Sir Ashley Fox branding the idea as a “disaster.” https://www.bridgwatermercury.co.uk/news/24878911.hinkley-point-c-edf-says-fish-issue-delay-new-plant-operation/
Trump calls North Korea a ‘nuclear power,’ drawing a rebuke from Seoul
Yahoo! News, Stella Kim, Wed, January 22, 2025
SEOUL, South Korea — Denuclearization of North Korea is a prerequisite for global stability, South Korea said Tuesday after President Donald Trump described the reclusive regime as a “nuclear power,” raising concern that the U.S. could be moving toward recognizing the North as a nuclear-armed state.
Since Trump was last in office, North Korean leader Kim Jong Un has vowed to “exponentially” boost his nuclear arsenal and ramped up weapons testing, including of missiles that could potentially strike the continental United States and overwhelm U.S. treaty ally South Korea.
The newly inaugurated Trump, who met with Kim three times during his first term to discuss North Korea’s U.N.-sanctioned weapons programs, spoke enthusiastically Monday about his past relationship with Kim, saying they liked each other.
“Now, he is a nuclear power,” Trump said while signing a series of executive orders in the Oval Office. “I think he’ll be happy to see I’m coming back.”
Trump’s defense secretary nominee, Pete Hegseth, also called North Korea a “nuclear power” during his Senate confirmation hearing last week.
While it is unclear what Trump and Hegseth meant by “nuclear power,” U.S. officials have long refrained from using the phrase as it could signal recognition of North Korea as a nuclear-armed state.
The Trump administration did not immediately respond to a request for comment Tuesday.
Though there is growing debate as to whether the international community should accept North Korea’s nuclear status, experts say doing so would significantly disrupt the geopolitical balance in the region and potentially set off an arms race, including the possible development of nuclear weapons by South Korea and Japan…………………………. https://www.yahoo.com/news/trump-calls-north-korea-nuclear-115137317.html
Indigenous group vows to stop nuclear waste shipments unless new deal struck

CTV News By Scott Miller, January 23, 2025
Leaders with the Saugeen Ojibway Nation (SON) say they are no longer willing to have their territory “exploited” for the production of nuclear energy and storage of radioactive waste.
“The nuclear issue has the biggest footprint in the Saugeen Ojibway Territory. It’s the biggest footprint bearing on the environmental imprint, so we need to start getting some of that stuff resolved,” said Chippewas of Nawash Unceded First Nation Coun. Paul Jones.
The SON is home to Bruce Power, the world’s largest operating nuclear station, as well as Ontario Power Generation’s (OPG) Western Waste Management Facility that houses most of Ontario’s nuclear waste.
That includes over one million used nuclear fuel bundles and approximately 100,000 cubic metres of low and intermediate level nuclear waste.
SON leadership say they didn’t agree to either nuclear facility being constructed in their territory, but they are left to deal with them on their traditional lands that stretch from Tobermory to Goderich.
“I believe there were some formal agreements with SON in 2018 and 2022. Since then, Ontario Power Generation has reneged (renegotiated) on some of those commitments, and it kind of put some of the talks on standstill for now,” said Saugeen First Nation Chief Conrad Ritchie.
To restart those talks about compensation for hosting a large portion of Ontario’s nuclear waste, SON has threatened to stop allowing shipments of nuclear waste into their territory unless “significant progress” is made “towards the resolution of nuclear legacy issues” within six months………………………………………………..
Although the plan is to eventually move the millions of used nuclear fuel bundles currently stored at the Western Waste Management Facility to a yet constructed underground facility in northern Ontario, the highly radioactive material will remain in Saugeen territory for many more decades, and that’s worth something, said SON leadership.
“We’re taking all the risk and there’s no benefits coming to SON,” said Jones.
“Hopefully we’ll come up with a good plan or a resolution that’s fair for all parties. And that Saugeen and Nawash get their equal share of operating within our traditional treaty territory,” said Ritchie.
The SON is comprised of the Saugeen First Nation and Chippewas of Nawash Unceded First Nation. Their traditional territories stretch from Tobermory east to Collingwood, and south to Arthur and Goderich. https://www.ctvnews.ca/london/article/indigenous-group-vows-to-stop-nuclear-waste-shipments-unless-new-deal-struck/
