If you are talking about [1], then others should know that the movie is a documentary thinly masquerading as a hard SF movie addressing an audience in the remote future. It's a pretty depressing movie; it is obvious they are constrained by politically-motivated budgets and making a relatively cursory effort to bury the waste, considering the goals involved. I'd rather see these geological waste repositories as endless projects combined with reprocessing to reduce waste volume at heavily-defended military bases; continue digging ever downwards, the waste stored at the deepest stable non-construction zone levels to date, with the materials for basalt-rebar reinforced concrete plugs along the entire path back to the surface ready to drop in at a moment's notice, over say 24 hours. If certain existential triggers are reached endangering the existence of the host nation-state, evacuate the tunnels and pull the plugs to fill in the tunnels. As the tunneling surpasses 2.5 km (a little past our current deepest tunnel), our confidence level in future generations drilling that deep and knowing about radioactivity dramatically increases.
