All they have to do is stick in in containers>transport to storage facility deep in mountain> DONE!
Unfortunately, bureaucracy gets the best of the whole transportation part. Lot's of places aren't willing to even have the trucks or trains with the waste roll through en route to storage. So instead of making a direct trip from reactor facility to storage, the waste is transported through a maze of BULLSHIT! Increasing risk of problems. However, when was the last time you heard of nuclear waste en route to storage being hijacked or crashing? Never.
