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.

Geohydrochemical factors that affect the transport of low-level wastes in saturated-unsaturated porous media are described. Depending on the availability of those geohydrochemical parameters and the detail of information desired, three levels of analyses can be undertaken. Two examples used to illustrate these three levels of analyses are the seepage pond problem and the shallow trench burial problem. The former example indicates that the lower level of resolution gives the more conservative estimate of the breakthrough time for the contaminant. The latter example exemplifies the cases that simple levels of resolution are not adequate nor possible because the flow variables and parameters cannot be determined with rational assumptions. The level 1 model can best be used for screening purposes while level 2 analysis can be employed to rank the alternative sites. Level 3 models should be used for detailed studies of the impact of the chosen site or for predictive assessment of operational sites and decomission scenarios.
