U.S. nuclear fuel recycling takes two steps forward
Late last week saw two announcements from companies working to recycle used nuclear fuel on a commercial scale, providing welcome news to anyone hoping to see the United States move to unlock the hidden potential of the more than 94,000 metric tons of spent fuel stored at power plant sites around the country.

The alpha channeling effect in tokamaks exploits the higher population of high-energy alpha particles in the tokamak interior compared to that of low-energy alpha particles at the periphery. Because of the population inversion, it is possible to inject waves that diffuse resonant particles along diffusion paths connecting these regions, so that hot alpha particles diffuse to the periphery and cool at the same time. This effect has been suggested as a way of achieving considerably higher performance in tokamak fusion reactors, and similar possibilities might be expected in mirror reactors.
