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.

A new approach has been proposed to solve the transport equation for nonuniform lattices. The assumptions made permit transformation of the response matrix scheme into a diffusion-type equation and the specification of the boundary conditions of the cell problems to be solved. The new approach uses quantities that can be considered as a generalization of the diffusion coefficient.
