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 increase in intensity of a 252Cf neutron source surrounded by uranium depleted in the 235U isotope has been measured, and the results of this experiment were used to determine of238U for 252Cf spontaneous-fission neutrons. The measurement was performed in the TRIGA Mark III reactor, using the multiplication property of a subcritical TRIGA core. A Monte Carlo calculation was performed, which employed ENDF/B-III data, to provide analytical results for comparison with the measurements. The source enhancement obtained using a depleted uranium cylinder surrounding the 252Cf source was measured to be (7.35 ± 0.20)% compared with a calculated value of (7.11 ± 0.15)%. The calculated results, using ENDF/B-III data, agree with the measurement within the uncertainty of the evaluated values of v and σƒ.
