Inside the world’s first nuclear waste tomb in Finland

The world’s first geological tomb for nuclear waste is rapidly taking shape more than 400 metres below the forests of Finland.

Batches of lethally radioactive uranium will start arriving within two years for burial in the warren of tunnels carved into the bedrock.

Other countries, including the UK, are considering plans to build their own geological disposal facilities, which should safely isolate the 260,000 tonnes of highly radioactive waste that has accumulated worldwide since the dawn of nuclear power in the 1950s.

Sky News was given rare access to the site, called Onkalo, which means “cavity” in Finnish. It is built next to three nuclear reactors on the country’s southwestern coast.

Security was so tight in the aftermath of the sabotage of the Nord Stream gas pipeline that there was a strict no-filming rule above ground.

But we were taken down the 5km access road that winds through the bedrock, so deep that our ears popped.

At the bottom, further tunnels fanned out. So far five have been completed, but up to 100 could be built over the coming decades, stretching to more than 40 miles in all.

Our guide was Sanna Mustonen, a geologist and senior project manager for Posiva, the company that runs the facility.

She said the bedrock was formed almost two billion years ago and has remained intact ever since.

“The rock itself, like in the whole area of Finland, is very stable,” she said.

“We have old rock. We don’t have continental plates nearby, so we don’t have any earthquakes, seismicity, or things like that.”

‘There must be security’

Like other countries Finland stores spent nuclear fuel above ground in shielded bunkers while it seeks a long-term solution.

But Mika Pohjonen, managing director of Posiva, said it would be irresponsible to leave such dangerous waste where it could fall into the wrong hands.

He told Sky News: “If you look at history, 300 years back, how many wars have there been in Europe, for example?

“On the surface the interim storage needs active measures from humans, the building needs to be heated, the spent fuel must be cooled, there must be security around it.

“If you look a generation forward you cannot really see that that kind of arrangement would be risk-free enough.”

Various solutions to the nuclear industry’s waste problem have been suggested, including: launching it into deep space, burying it in an ocean trench and dropping it into a fissure in the Earth’s crust.

They’ve been dismissed as unfeasible, expensive or environmentally risky.

‘Safe for one million years’

Instead, Posiva will encase spent nuclear fuel in double-layered metal cannisters that will slot into holes bored in the floor of the tunnels.

To keep them dry, they will be swaddled in bentonite, an absorbent material used in cat litter.

More bentonite will be used to backfill the tunnels, which will be plugged with concrete.

When the complex is full in around a century’s time, with perhaps as many as 3,250 cannisters, it will be sealed up and all trace removed above ground.

“It will be safe for one million years,” Mr Pohjonen said.

“There may not be humans here any more because in that time there will be ice ages or [this area will be] underwater but this is designed to keep it out of the biosphere.”

Dummy cannisters are already buried in bentonite and surrounded by sensors.

Some scientists have warned water could corrode the metal, become radioactive and then rise to the surface over millennia.

But Posiva says the multiple barriers keep the waste in and water out. And if there was a leak in a highly unlikely worst-case scenario, modelling shows that by the time any water reached the surface in 10,000 years the radioactivity would have decayed so much that it would not be a threat to life.

Finland’s progress has been watched closely by other countries. Sweden has begun construction of its own deep geological disposal site. France, Switzerland and the UK are further behind.

A shortlist of four possible sites in Cumbria and Lincolnshire has been drawn up.

Bruce Cairns, chief policy adviser at the UK’s Nuclear Waste Services, was also taking a look at Onkalo while we were there.

He said responsible permanent disposal for waste is essential as the country commissions a new generation of reactors.

“We have 70 years’ worth of waste in the UK that’s already accumulated from energy production, defence and industrial processes.

“It’s not going anywhere unless we do something with it. We have to take action to make sure this is managed responsibly, not just for now but for the long term as well.”

Key to Finland’s progress has been engagement with the local community.

Locals in favour

The nearest settlement is Eurajoki, about 10 miles away.

The existing nuclear reactors were already big local employers and when the area was selected from a shortlist of disposal sites the local authority voted overwhelmingly in favour.

Vesa Lakaniemi, the town’s mayor, said: “We have had nuclear power here for 40 years.

“People know about nuclear and final [waste] disposal much more than in the areas which don’t have a nuclear power plant.

“Trust has developed over four decades.”

Court confirms sacking of South Korean president who declared martial law

South Korea’s constitutional court has confirmed the dismissal of President Yoon Suk Yeol, who was impeached in December after declaring martial law.

His decision to send troops onto the streets led to the country’s worst political crisis in decades.

The court ruled to uphold the impeachment saying the conservative leader “violated his duty as commander-in-chief by mobilising troops” when he declared martial law.

The president was also said to have taken actions “beyond the powers provided in the constitution”.

Supporters and opponents of the president gathered in their thousands in central Seoul as they awaited the ruling.

The 64-year-old shocked MPs, the public and international allies in early December when he declared martial law, meaning all existing laws regarding civilians were suspended in place of military law.

After suddenly declaring martial law, Mr Yoon sent hundreds of soldiers and police officers to the National Assembly.

He has argued that he sought to maintain order, but some senior military and police officers sent there have told hearings and investigators that Mr Yoon ordered them to drag out politicians to prevent an assembly vote on his decree.

His presidential powers were suspended when the opposition-dominated assembly voted to impeach him on 14 December, accusing him of rebellion.

The unanimous verdict to uphold parliament’s impeachment and remove Mr Yoon from office required the support of at least six of the court’s eight justices.

South Korea must hold a national election within two months to find a new leader.

Lee Jae-myung, leader of the main liberal opposition Democratic Party, is the early favourite to become the country’s next president, according to surveys.

Stock markets suffer sharp drops after Donald Trump announces sweeping tariffs

Stock markets around the world fell on Thursday after Donald Trump announced sweeping tariffs – with some economists now fearing a recession.

The US president announced tariffs for almost every country – including 10% rates on imports from the UK – on Wednesday evening, sending financial markets reeling.

While the UK’s FTSE 100 closed down 1.55% and the continent’s STOXX Europe 600 index was down 2.67% as of 5.30pm, it was American traders who were hit the most.

Trump tariffs latest: US stock markets tumble

All three of the US’s major markets opened to sharp losses on Thursday morning.

By 8.30pm UK time (3.30pm EST), The Dow Jones Industrial Average was down 3.7%, the S&P 500 opened with a drop of 4.4%, and the Nasdaq composite was down 5.6%.

Compared to their values when Donald Trump was inaugurated, the three markets were down around 5.6%, 8.7% and 14.4%, respectively, according to LSEG.

Worst one-day losses since COVID

As Wall Street trading ended at 9pm in the UK, two indexes had suffered their worst one-day losses since the COVID-19 pandemic.

The S&P 500 fell 4.85%, the Nasdaq dropped 6%, and the Dow Jones fell 4%.

It marks Nasdaq’s biggest daily percentage drop since March 2020 at the start of COVID, and the largest drop for the Dow Jones since June 2020.

‘Trust in President Trump’

White House press secretary Karoline Leavitt told CNN earlier in the day that Mr Trump was “doubling down on his proven economic formula from his first term”.

“To anyone on Wall Street this morning, I would say trust in President Trump,” she told the broadcaster, adding: “This is indeed a national emergency… and it’s about time we have a president who actually does something about it.”

Later, the US president told reporters as he left the White House that “I think it’s going very well,” adding: “The markets are going to boom, the stock is going to boom, the country is going to boom.”

He later said on Air Force One that the UK is “happy” with its tariff – the lowest possible levy of 10% – and added he would be open to negotiations if other countries “offer something phenomenal”.

Economist warns of ‘spiral of doom’

The turbulence in the markets from Mr Trump’s tariffs “just left everybody in shock”, Garrett Melson, portfolio strategist at Natixis Investment Managers Solutions in Boston, told Reuters.

He added that the economy could go into recession as a result, saying that “a lot of the pain, will probably most acutely be felt in the US and that certainly would weigh on broader global growth as well”.

Meanwhile, chief investment officer at St James’s Place Justin Onuekwusi said that international retaliation is likely, even as “it’s clear countries will think about how to retaliate in a politically astute way”.

He warned: “Significant retaliation could lead to a tariff ‘spiral of doom’ that could be the growth shock that drags us into recession.”

It comes as the UK government published a long list of US products that could be subject to reciprocal tariffs – including golf clubs and golf balls.

Running to more than 400 pages, the list is part of a four-week-long consultation with British businesses and suggests whiskey, jeans, livestock, and chemical components.

Meanwhile, Prime Minister Sir Keir Starmer said on Thursday that the US president had launched a “new era” for global trade and that the UK will respond with “cool and calm heads”.

It also comes as Canadian Prime Minister Mark Carney announced a 25% tariff on all American-imported vehicles that are not compliant with the US-Mexico-Canada trade deal.

He added: “The 80-year period when the United States embraced the mantle of global economic leadership, when it forged alliances rooted in trust and mutual respect and championed the free and open exchange of goods and services, is over. This is a tragedy.”

Donald Trump announces sweeping global trade tariffs - including 10% on UK imports

Donald Trump has announced a 10% trade tariff on all imports from the UK – as he unleashed sweeping tariffs across the globe.

Speaking at a White House event entitled “Make America Wealthy Again”, the president held up a chart detailing the worst offenders – which also showed the new tariffs the US would be imposing.

“This is Liberation Day,” he told a cheering audience of supporters, while hitting out at foreign “cheaters”.

He claimed “trillions” of dollars from the “reciprocal” levies he was imposing on others’ trade barriers would provide relief for the US taxpayer and restore US jobs and factories.

Mr Trump said the US has been “looted, pillaged, raped, plundered” by other nations.

His first tariff announcement was a 25% duty on all car imports from midnight – 5am on Thursday, UK time.

Mr Trump confirmed the European Union would face a 20% reciprocal tariff on all other imports. China’s rate was set at 34%.

The UK’s rate of 10% was perhaps a shot across the bows over the country’s 20% VAT rate, though the president’s board suggested a 10% tariff imbalance between the two nations.

It was also confirmed that further US tariffs were planned on some individual sectors including semiconductors, pharmaceuticals and critical mineral imports.

The ramping up of duties promises to be painful for the global economy. Tariffs on steel and aluminium are already in effect.

The UK government signalled there would be no immediate retaliation.

Business and Trade Secretary Jonathan Reynolds said: “We will always act in the best interests of UK businesses and consumers. That’s why, throughout the last few weeks, the government has been fully focused on negotiating an economic deal with the United States that strengthens our existing fair and balanced trading relationship.

“The US is our closest ally, so our approach is to remain calm and committed to doing this deal, which we hope will mitigate the impact of what has been announced today.

“We have a range of tools at our disposal and we will not hesitate to act. We will continue to engage with UK businesses including on their assessment of the impact of any further steps we take.

“Nobody wants a trade war and our intention remains to secure a deal. But nothing is off the table and the government will do everything necessary to defend the UK’s national interest.”

The EU has pledged to retaliate, which is a problem for Northern Ireland.

Should that scenario play out, the region faces the prospect of rising prices because all its imports are tied to EU rules under post-Brexit trading arrangements.

It means US goods shipped to Northern Ireland would be subject to the EU’s reprisals.

The impact of a trade war would be expected to be widely negative, with tit-for-tat tariffs risking job losses, a ramping up of prices and cooling of global trade.

Research for the Institute for Public Policy Research has suggested more than 25,000 direct jobs in the UK car manufacturing industry alone could be at risk from the tariffs on car exports to the US.

The Society of Motor Manufacturers and Traders (SMMT) had said the tariff costs could not be absorbed by manufacturers and may lead to a review of output.

The tariffs now on UK exports pose a big risk to growth and the so-called headroom Chancellor Rachel Reeves was forced to restore to the public finances at the spring statement, risking further spending cuts or tax rises ahead to meet her fiscal rules.

A member of the Office for Budget Responsibility (OBR), David Miles, told MPs on Tuesday that US tariffs at 20% or 25% maintained on the UK for five years would “knock out all the headroom the government currently has”.

But he added that a “very limited tariff war” that the UK stays out of could be “mildly positive”.

He said: “There’s a bit of trade that will get diverted to the UK, and some of the exports from China, for example, that would have gone to the US, they’ll be looking for a home for them in the rest of the world.

“And stuff would be available in the UK a bit cheaper than otherwise would have been. So there is one, not central scenario at all, which is very, very mildly potentially positive to the UK. All the other ones which involve the UK facing tariffs are negative, and they’re negative to very different extents.”
