Indeed, signal-to-noise ratio on the modern web is fairly challenging search space, but there was DoE documentation out there showing near zero practical success rate at actual long-term disposal sites. Every site has shown some concrete degradation within years, reported incidents, water ingress, and persistent operational costs. Current methodology is to pile up waste near cooling ponds, and lie to people about dealing with it at some point in the future.

My point was, few organizations have ever shown actual success with what they claimed would happen. Thus, arguing sites will hold for 75 years let alone 30k years is a fools errand. Water fills holes in the ground, and will likely continue to do so in the future. =3
