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.

In this Note we report on a technique for determining a two-dimensional time-dependent response function using a one-dimensional solution of the transport equation for a homogeneous medium. Basic to this technique is the calculation of the adjoint function. We have determined the asymmetric energy deposition rate in air from a spatial asymmetric source as an example of the method.
