General Matter to build Kentucky enrichment plant under DOE lease
The Department of Energy’s Office of Environmental Management announced it has signed a lease with General Matter for the reuse of a 100-acre parcel of federal land at the former Paducah Gaseous Diffusion Plant in Kentucky for a new private-sector domestic uranium enrichment facility.

Fission product fractional release rates, K, used in the Albrecht-Wild model and measured at Kernforschungszentrum Karlsruhe and Oak Ridge National Laboratory can be fitted well by a single straight line for each fission product over the entire temperature range of the data when ln K is plotted as a function of 1/T. Past applications of the Albrecht-Wild model have used plots of ln K versus T, which required three fits over the temperature range. Thus it is suggested that fractional release rates be represented by the Arrhenius form, K=K0exp(−Q/RT).
