The thing is, thanks to the magic of nonzero interest rates, it's cheaper to wait and reprocess later. The more you wait, the cheaper it is, even including the cost of temporary storage in dry casks while you wait.

That's putting a lot on the assumption of exponential growth over the time span of 10,000 years.

If the assumption fails and interest rates go to zero and stay there, we can reprocess then. In the meantime, if we can invest the money elsewhere and delay reprocessing we come out ahead.
