“In a few years, Finland will begin depositing spent nuclear fuel underground in Onkalo, where it will remain for millennia. Erika Benke describes her experience of visiting the site.
“… Spent fuel rods from nuclear power stations are currently kept in temporary storage facilities around the world.
“Finland is the first country implementing what it hopes is a permanent solution. Starting in two or three years, highly radioactive waste will be buried deep in the bedrock at Onkalo, after being encased in cast-iron and copper cylinders and wrapped in bentonite clay.”
