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.

A recently reported description of radiative transfer is generalized to the case of a linear transport equation containing a Fokker-Planck treatment of very peaked scattering. The resulting diffusion theory is naturally flux (current) limited; i.e., the magnitude of the current cannot exceed the scalar flux. It is shown that the effect of the Fokker-Planck terms is, within this theory, identical to treating the very peaked scattering via the classical transport correction to the scattering cross section. This description of linear transport has potential application in charged-particle and high-energy neutron transport calculations.
