“its cool because we could use it in process we don’t have yet but might in the future”

Is it quote from 60-ies? We have. At least Russia has. US had too.

Right now almost 100% of waste is stored on site above ground because they really have no good solution.

You mean there’s so little they don’t even need a dedicated facility for it, and it’s safe enough that people are willing to work where it’s stored? Sounds great!
