NNSA awards BWXT $1.5B defense fuels contract
The Department of Energy’s National Nuclear Security Administration has awarded BWX Technologies a contract valued at $1.5 billion to build a Domestic Uranium Enrichment Centrifuge Experiment (DUECE) pilot plant in Tennessee in support of the administration’s efforts to build out a domestic supply of unobligated enriched uranium for defense-related nuclear fuel.

The one-speed neutron transport equation with anisotropic scattering is investigated by the method of partial-range Legendre-polynomial analysis. It is found that appropriate conditions on the spatial moments can be specified by suitable integral operations of the partial-range polynomials. A numerical test suggests that such an analysis does possess potential merit for calculating some neutron transport parameters to a high degree of accuracy even in a low order approximation.
