I mean, really the only thing that’s gonna expose them is plate tectonics. Just to give a sense of scale, America and Europe are diverging by 4 cm/yr, so will be 500 metres farther from each other, horizontally, in about 10,000 years. Geologically stable regions (called cratons) would not experience such motion vertically for much, much, much longer.

[…] will consist of 60 km of tunnels buried 500 metres down in 1.9 billion year old bedrock.
Are 500 meters deep enough?

500m is the industry standard depth for deep geological repositories for nuclear waste

But is that enough? I rarely trust industry standards.

It’s way more than is needed to block any radiation.

I think that’s still being debated or decided it refined. Warnings or signage need to be interpreted correctly in 80,000 years.

Google hostile architecture for nuclear waste sites.
It’s better than a skull and crossbones in my opinion
