In Finland, an innovative project called Onkalo is about to redefine the concept of isolation. This underground complex, located near the Olkiluoto nuclear power plant, was designed to store nuclear waste safely for an impressive 100,000 years. After being sealed in 2025, no human will be able to access the site, a historic milestone in the sustainable management of nuclear energy.
Onkalo, translated as “cave” in Finnish, is more than just a curious name. It represents a bold and necessary response to one of humanity’s greatest challenges: the safe storage of nuclear waste. Developed by Posiva, a Finnish waste management organization, the site is an intricate network of tunnels and chambers dug 450 meters deep, designed to withstand geological changes and the passage of time.
BBC journalist Erika Benke was one of the few people to visit this space before its permanent closure. “It takes 15 minutes by car to descend the 437 meters to the Onkalo service station,” Benke reported, describing the 4.5-kilometer tunnel with its solid rock walls and minimal lighting. At some points, the ground becomes damp and muddy, a reminder that the environment there is inhospitable even for humans.
In The Heart Of Onkalo

The used nuclear fuel will be sealed in airtight containers and deposited in vertical holes. The operation relies on robots designed to ensure precision and safety, far from human touch. These measures are essential to protect the radioactive material from future generations and from nature itself, which can be unpredictable over such long periods.

A Challenge Beyond Human Time
Understanding a period of 100,000 years is an almost impossible exercise for any human. For comparison, this span is equivalent to 4,000 generations. 100,000 years ago, the planet was a place dominated by woolly mammoths and the first humans were beginning to explore the world outside of Africa.
This horizon of time makes Onkalo a monument to Finland’s commitment to environmental responsibility. The international community has already applauded the boldness and technical sophistication of the project, which combines natural and artificial barriers to safely isolate nuclear waste.
The Legacy of Onkalo
Starting in 2025, Onkalo will be sealed, leaving behind a silent mission: to protect humanity and the environment from dangerous nuclear waste until nature itself makes it safe. Beneath the serene landscape of southwestern Finland, Onkalo will continue its work, invisible, while the history of humanity continues its course.
In this underground tunnel where no human will ever step again, science, ethics, and technology converge to leave a legacy that transcends our time.

C’est un début… Parce que l’homme a détruit une grande partie de la planète Terre, quelqu’un doit faire la différence, beaucoup voyagent dans l’espace comme des dessins animés…plus Chaque vie est importante ! Protéger est la moindre des choses ! La vérité est que certains pays se battent pour avoir un monde meilleur… Et d’autres ne pensent qu’au capitalisme (je ne sais pas comment à l’avenir ils feront de l’argent une nourriture, alors que la planète ne produit rien d’autre ! Naturellement, comme ils le font déjà) produisent des produits synthétiques, en relation avec les médicaments… soja transgénique et ainsi de suite, avec le sol contaminé par des pesticides et chaque jour ils fabriquent de nouvelles formules de poison qui éliminent de nombreuses vies d’insectes (et d’autres vies aussi) qui ont été créées naturellement pour protéger la faune et la flore.
Pq simplesmente não joga no espaço? Muito mais seguro do que ficar fazendo cemitério nuclear na terra…
Matéria curiosa e interessante
Porem alguns querem impor ou mostrar sua idolatria, totalmente apaixonados pelo sistema das regalias e do poder
Vcs juram de pé junto que seu ídolo seriano melhor, faria o melhor por nós, mas quem sobe la acaba na jogatina, se vc fizer isso ooooo , vamos tirar isso, e por ai vai
Então não seja uma escoria ofendendo e humilhando os outros, ou pior sendo até na força de um racismo
Tenha mente mais uns graus mais evoluído
De que sendo DIREITA ou ESQUERDA todos vão nos ferrar, não vão votar em retirar suas regalias, não vão cortar suoer salários ameaçando se aposentarem em massa
E por ai vai
Abraco aos políticos de plantão
