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 study is made of the kinetics equations associated with two group reactor theory. The method involves expansions of each of the fluxes in an infinite series, each term of which is a product of a space-dependent eigenfunction and a time-dependent factor. Techniques are provided for the rigorous determination of transient flux shapes as well as the eventual stable or asymptotic flux shapes.
