DOE, General Matter team up for new fuel mission at Hanford
The Department of Energy's Office of Environmental Management (EM) on Tuesday announced a partnership with California-based nuclear fuel company General Matter for the potential use of the long-idle Fuels and Materials Examination Facility (FMEF) at the Hanford Site in Washington state.
According to the announcement, the DOE and General Matter have signed a lease to explore the FMEF's potential to be used for advanced nuclear fuel cycle technologies and materials, in part to help satisfy the predicted future requirements of artificial intelligence.

The absolute value of the total neutron cross section of U235 was measured for neutrons in the energy range 0.000818 to 0.0818 ev for two types of samples, metallic foils and D2O solutions of uranium. Balanced solutions of U235O2(NO3)2 and U238O2(NO3)2 were used to determine the difference between the total cross sections of U235 and U238. This value when combined with the relatively small, known value of the total cross section for U238 gives σT(U235) = 695.0 ± 1.8 barns at 0.0253 ev. The measurements on the metallic U235 foils agreed with the measured total cross section determined from the liquid solution data to better than 1%, yielding σT(U235) = 698.7 ± 4.7 barns at 0.0253 ev. The measured value of the U235 total cross section at 0.00291 ev combined with the scattering cross section, a recent precise value of (1 + α) at 0.00291 ev, and the ratio σf (0.0253 ev)/σf (U235) = 590.8 ± 5.4 barns at the standard neutron energy of 0.0253 ev.
