Here is my idea for disposing of nuclear waste and making use of nuclear power more acceptable. Uranium makes a great projectile, right? We build a massive rail gun somewhere in the desert package the spent uranium in a case of some sort and fire it out of earth orbit into the sun. Is there any reason this will not work?

Oh, sure. Now we are going to contaminate the surface of our sun!

No need to bother.

It is fine to reprocess it in breeder reactors, and ultimately bury what is left in Nevada.

Yep. to fire anything into the sun means you have to cancel the Earth orbital speed relative to the Sun of 30 km./s.
That's about twice the speed you would need to give your projectile if you wanted it to reach any star within 100 light years (other than the Sun).
