Ah, 1 in 100 does indeed sound quite risky. I assumed it was much better than that.
Even transporting waste via rail or road requires a container that would survive any conceivable surface level collision. If you apply that philosophy to a space launch... well you looking at a very uneconomical ratio of container to waste, even if rocket launches were thousands of times more likely to be successful.
Yes, I've seen one of those nuclear transporting rail carriages (and the video of what happens when you crash a train into it) and they are pretty substantial to fire into space.
