Maybe. I saw a Google X talk a couple years ago from some grad students at MIT that wanted to build a nuclear power plant that closed the fuel cycle loop. (which is what you're talking about). They made some very grand promises about how this would solve the HLW problem.

Unfortunately a few years later they had to issue a correction, because older (more experienced) engineered stepped in and showed them where the mistakes in their work were, and they couldn't eliminate nearly as much HLW as they thought with existing technology.

In other words, a closed nuclear fuel cycle doesn't exist. We could be better than we are currently with investments in molten salt and fast reactors, but I don't think we know how to get to zero HLW using fission.

Considering that HLW lasts for a million years, that's imposing too high a cost on too many of our descendants, IMO.

My personal belief is that solar and wind are the best way to go for now, and if we ever get zero-HLW fission or aneutronic fusion working, cool.
