I worked on degrading high-level nuclear waste using neutron products from fusion reactions: basically one of the only ways to remove weapons-grade nuclear products from the world. We'd call this "keeping stray nukes from terrorists" now, I suppose. This was partly a political hack to get funding for sub-breakeven fusion reactors, but it works just as well as a rationale for investing in a reactor technology which could actually break even and produce power. So let's do it! Let's break down that high-level nuclear waste!
