Do nuclear power plants have nuclear waste?

Yes, and a lot of it too! There is no permanent storage so they put the casks in a pool of boric acid so the waste can cool down. A problem is that the pools are becoming overcrowded and people need to fine a permanent storage instead of a temporary one..They found a place in Yucca Mountain a while back ago and i dont know what has happened since but it was supposed to be 1500 feet underground (personally i think thats not enough). A lot of questions have come up though. One of them being if the waste can be shot into space. I think we've messed up Earth enough so why mess up space?
