0ur depth at the moment is about 430 metres. eventually, they'll hold 6,500 tonnes of spent uranium — all the waste finland's five reactors will ever produce. it takes hundreds of thousands of years for radioactive waste to safely decay. and this underground tomb is the final resting place for finland's spent nuclear fuel. the bedrock here is almost two billion years old, and geologists think it's ideal for a nuclear graveyard. and the whole western finland is located in a really stable, geologically stable area. we have hardly any earthquakes, and the ground weather conditions are good for ...

Into holes in the rock before it's sealed off with clay and a thick concrete plug. most radioactive waste is temporarily stored — is temporarily stored in pools above ground. and worldwide, around 260,000 tonnes are piling up. but finland believes a geological tomb like this offers a safer solution. you need to cool down the spent fuel for a0 years. world is full of those temporary storages and almost all of that, this waste is ready to be put to its final place. you might imagine that few would welcome such a facility in their backyard, but two thirds of finns support nuclear energy. and in...

Geological, stable area. geologically stable area. we have hardly any earthquakes, and the ground weather conditions are good for our concept. in a final disposal facility... remote—controlled machines will do the work — slotting five—metre copper canisters into holes in the rock, before it's sealed off with clay and a thick concrete plug. most radioactive waste is temporarily stored in pools above ground. and worldwide, around 260,000 tonnes are piling up. but finland believes a geological tomb like this offers a safer solution. you need to cool down the spent fuel for 40 years. the wor...

Remote controlled machines, will do the work slotting five metre copper canisters into holes in the rock before it's sealed off with clay and a thick concrete plug. so this is how most radioactive waste is temporarily stored in pools above ground. and worldwide, around 260,000 tonnes are piling up. but finland believes a geological team like this a geological tomb like this offers a safer solution. you need to cool down the spent fuel for a0 years. world is full of those temporary storages and almost all of that, this waste is ready to be put to its final place. you might imagine that few woul...

Advantage in environmental terms. and there's indeed barely any evidence of the compressed air energy storage above the surface and if you intrusions on nature lower down. so we have a five metre concrete plug can withstand the pressure in the cabin and the steel door keeps everything medically sealed that so the mountain is sealed tight the back of us we have a continuous water supply from the mountain so no air can escape. the real innovation in the heart of the system is this heat accumulator that raises efficiency from fifty to over seventy percent. as the air is compressed heat is generat...
