Lets see if we can go a couple of decades without any rocket explosions at all before we risk burning up radioactive waste in the upper atmosphere. I don't want to trust this on mere claims of safety, I want to trust statistics on large, non-cherry-picked numbers of launches.

Have we gone decades without plane crashes? What's with this insanity that seems to grip even supposedly educated science-minded people whenever something involves nuclear technology?

Do you think we should be using planes to send nuclear waste into the upper atmosphere? > What's with this insanity that seems to grip even supposedly educated science-minded people whenever something involves nuclear technology? Maybe the educated science-minded people have a better understanding of some of the risks involved. I once heard that 1 kg of plutonium burning up in the upper atmosphere would be enough to wipe out humanity. Now I don't know the math behind that claim, and of course I know that most nuclear waste is not plutonium, but I would much rather be safe than sorry with things like burning up radioactive waste in the upper atmosphere. Especially in the face of superior alternatives like putting it deep underground.

    What you're probably thinking of is the statistic that a pound of plutonium oxide would cause cancer in 2 million people. A more detailed look into the matter shows that even that is very likely overblown: http://spiff.rit.edu/richmond/answers/llnl.html http://spiff.rit.edu/richmond/answers/llnl.html You simply couldn't possibly spread it enough with enough density to be both inhalable and common enough to measurably increase cancer risk. While I agree that just putting it in the ground is the superior solution, my point is that fears of putting nuclear material on modern American rockets are very exaggerated.

      It's entirely possible it's overblown, but I'm pretty sure we're talking about larger amounts than that if we're using this to get rid of our nuclear waste. But even apart from the launch risk, shooting stuff into space is not cheap, and shooting stuff into the sun is a lot more expensive than that. To justify that, it has to be not only safer, but also cheaper than putting it underground. The only real advantage I see to shooting it into the sun is that if our civilisation ever collapses and nobody can read anymore, there's less risk of the people then running into our waste in the sun than finding it buried.
