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…
