Nuclear Waste?

If nuclear power leaves a small carbon footprint, but the waste is so bad that people fret using it, why not send the waste into space? Send it on a ship aimed at the sun and let the waste burn up in the solar atmosphere? What kind of fallout would effect the universe since space is already a radioactive environment?

Odd creature in my backyard?
