Sort of like my own personal stance on 'breeder reactors' being 'waste reduction reactors'.

The problem with most of that 'waste' (at least the non-byproducts kind) is that it's exactly that, actual waste instead of burnt fuel.

What about "spent nuclear waste reactors"? It's a big long-winded, but fully conveys that it runs on spent nuclear waste. I suppose it could be parsed weirdly.
