I thought that was what fast breeder reactors did.
They have only low grade waste. The disadvantage is that you don't get free plutonium to put in your nukes
There are some political ramifications to admitting that you use plutonium from civilian reactors to make nuclear weapons. It's possible that they're doing this without admitting it and that's the reason reactors that consume rather than produce plutonium are disfavored. But in that case you still don't have a "waste storage problem" -- you know what you're doing with the plutonium, you're just not admitting to it.
But I don't think the scale adds up for that. We don't need this amount of plutonium to make weapons, even if that's what we're doing with some of it. So still destroy the rest of it.
