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 Greuling-Goertzel approximation is applied to the calculation of neutron slowing down in heavy water in the B1 and P1 approximations. Numerical calculations of the flux and nonescape probability assuming constant cross sections indicate the “inconsistent” G-G B1 approximation to be the most favorable. Existing machine codes can readily be modified to this method.
