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.

A method for obtaining spherical harmonic or PL solutions of the transport equation from discrete ordinate or SNcodes is developed in this paper. This method depends on a new interpretation of the method as a projection method. The technique of converting SNsolutions into spherical harmonic solutions is discussed in detail for x-y geometry, and numerical results are presented. The method of this paper differs from earlier methods in that SN solutions can be converted to PN-1 solutions.
