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 ratios σγ(238U)/σ/(235U), σγ(238U)/σγ(239Pu), and σf (239Pu)/σf (235U) have been measured in the energy range 130 to 1400 keV. The activation technique was used to determine the capture rate in 238U. The 278 keV γ ray emitted in the decay of 239Np was detected by means of a Ge(Li) detector. The counting efficiencies have been absolutely determined for the measurement of σγ(238U)/σf(239Pu). For the determination of the ratio σγ(238U)/σf(235U) the counting efficiencies have been eliminated by a measurement of the ratio at thermal-neutron energies. The ratio σf(239Pu)/σf(235U) has been measured in a back-to-back gas scintillation counter using the time-of-flight method for background suppression. The measurements resulted in an overdetermination of two unknown quantities by three measured values. The fitted values derived from the collective results were in good agreement with the individual measured ratios.
