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 thermal-neutron flux produced by a 252Cf spontaneous fission neutron source was computed for various spherical assemblies with moderators of iron, aluminum, carbon, D2O, beryllium, and H2O and reflectors of H2O and carbon. Consideration of spherical assemblies with a 252Cf source located at the center and at various distances from the center lead to a configuration, adaptable to neutron radiography, that has a small thermalization factor and a flat thermal-neutron flux.
