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.

The 23Na(n,2n) reaction produces the radioactive product 22Na, with a half-life of 2.61 years. For sodium-containing systems this reaction can result in a radioactive contamination problem. Currently available experimental cross sections for this reaction are in strong conflict. Comprehensive nuclear model calculations performed as part of the sodium evaluation for ENDF/B-V are in agreement with one of the experimental data sets. Acceptance of this data set results in an (n,2n) cross section larger than was given in ENDF/B-IV by ∼37% at 15 MeV and by as much as a factor of 4 at 20 MeV.
