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.

Thermal conductivity of electroplated gold at cryogenic temperatures is an important parameter for predicting the thermal behavior of ignition hohlraums that will eventually be fielded on the National Ignition Facility. We have measured the ratios between the electrical conductivities at 4.2 K and room temperature for electroplated gold as a function of bath brightener concentration and plating current density. By using the Weidemann-Franz law we predict thermal conductivities of these samples. We find that even small amounts of bath brightener drastically reduce the conductivities, and that the conductivities have a strong dependence on plating current density.
