The facility will be underground, where nuclear waste will be stored in a series of tunnels carved from stone and bedrock.
"Work on the concept behind the facility commenced in 1970s and the repository is expected to be backfilled and decommissioned in the 2100s. None of the 40 people working on the facility today will live to see it completed.
The bunker is based around a spiraling track that will eventually be three miles long, and reach a depth of 500 meters."

So the Mechas digging down through the Finnish Ice Cap will no doubt think to themselves, "The extinct hominids wouldn't have taken so much trouble unless something very, very, valuable was being stored away -- it must be their complete genetic code engraved on platinum-iridium tablets! We'll recreate them!", then proceed to excavate Onkalo and get their silicon synapses blasted by the still radiating waste...
(Yes, ripped off shamelessly from 'A.I', which shamelessly ripped off Arthur C. Clarke's 'History Lesson')
Wonderful - when our whole species is dead and gone, our only memorials will be the worst of the worst waste products our technologies produced.
