What do they do with nuclear waste now?

They could try using it to plug leaking oil wells.

Chris Back was banned

I know this is off topic,but why did that happen? I'm just curious what someone has to do to get banned.

 Now on topic. I'm all for nuclear power.It would help cut back on the need for oil.The only problem is the waste and what to do with it. Shooting it into the sun makes sense. The big problem with that is what Mr.Byrne pointed out. There are so many scientifically illiterate people out there that will worry about the environmental impact on the sun and oppose the idea.

Is there no option to reuse the nuclear plant waste in a lesser application, or is it truly spent?

There is, Michael; it's called nuclear transmutation, but unfortunately, it's been a political victim here in the US.  Our European friends, however, seem to be more commited to it. 

Though I've been reading about it since I was a teenager (hey, I loved Firestorm comics), I'm not going to attempt to describe it because I won't get it entirely correct, but I do encourage all of you reading this to look into it; my understanding is that it's safe and efficient, and quite possibly a necessary step toward a scientificly viable and economicly justifiable fusion reactor.
