This is not waste. This is weapons grade fissile material. It was taken to Oak Ridge for storage and very likely used to maintain the US nuclear weapons stockpile. Most nuclear waste really isn't that scary and even when it's scary it's not scary for very long. i.e the half life of the really nasty stuff is pretty short. Also storing it under water or in concrete is generally good enough. We only really worry about leakage into groundwater etc when thinking about very long term storage. Basically risks/worries about nuclear waste are massively overblown, humans have a hard time comprehending large numbers in relation to other large numbers. They see long half life and that is it, few stop to consider concentration etc. TLDR: stuff in article not waste. Stored securely at national labs and weapons facilities or shoved into bombs.
