There are a few points on recycling nuclear waste: 1. We can and have done it in the past (see EBR-1 where we proved breeding in addition to recycling in 1952) 2. It is extra expensive; uranium is relatively cheap and would have to become ~3x more expensive before recycling was economical 3. Storing existing nuclear waste is relatively easy from a technical point of view because there's so little of it. Finland is moving forwards with their Onkalo repository as case in point. 4. Breeding and recycling is likely necessary if we go world-scale with nuclear and produce more like 50% of primary world energy rather than 4% 5. It's not unreasonable to do once-through now with deep geologic repositories and then switch to billion-year sustainable breeding/recycling if and when we build 3000 new gigawatt scale reactors.
