Rotating plasmas as mass filters for nuclear waste

High-throughput mass filters can be a critical tool in the disposal of high level nuclear waste.~ The fission product is the most radioactive part of the nuclear waste and is responsible for most of the heat generation, although it is only a small fraction of the mass.~ Rotating plasmas can efficiently separate fission product from nuclear waste because every species in a particular mass group can be removed simultaneously.~ We compare quantitatively the performance of the plasma centrifuge, Ohkawa mass filter, and asymmetric centrifugal trap in separating fission product from nuclear waste.
