It will be worthwhile to test this process in the real world and to see how it compares to other methods of waste separation. While the natural gaidonnayite mineral is super rare, it can be synthesized in the lab, and it's really easy to make a bunch of it. Even though policymakers cannot agree on a location to store spent nuclear fuel, I am hopeful that this research (and the work of other researchers, see review here) will encourage politicians, the nuclear industry, and other community stakeholders to make progress toward limiting potential ecological disasters by sequestering away the most harmful parts of nuclear waste.
