True, they haven’t stored any waste yet but the facility is completed. And depending on how you look at it, it could be 100,000 years before you know for sure

True, they haven’t stored any waste yet but the facility is completed. And depending on how you look at it, it could be 100,000 years before you know for sure if it works, so my claim that it’s a ‘solved problem’ is a bit strong. I’ll retract that and say that it’s the most promising idea for nuclear waste disposal, one that that is close to beginning operations.
