nuclear waste solution

obama's main qualm with nuclear power is that we don't have a good strategy for dealing with the waste. what i would like to know is exactly how much waste is generated? we currently have made many advancements with heavy launch systems. am i proposing to just maroon the stuff to float around above the atmosphere to maybe re-enter at some point or worse yet hit other space debris? absolutely not. instead, launch the stuff in canisters and set them on a trajectory to take them straight into the heart of the sun. of course, i can already hear the howls of protest about how we shouldn't pollute the sun. pollute the sun? how? first of all, that would assume that the material ever even reaches the sun intact. secondly, the sun is nothing but a giant nuclear powerplant itself. seeing that the sun > 98% of the solar system's mass, no ammount of material we throw at it will make an appreciable difference. so let's quit wasting money digging holes in the ground and lining them with concrete and just launch the debris already. if someone is really worried that we might harm the sun, then launch it out of the solar system instead. and as an added bonus, put nominal instruments on them to measure random stuff along the way.
