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.

An investigation has been made of the effects of helium, ethane, propane, nitrogen, and carbon dioxide as contaminants in methane used as the filling gas for a proportional counting tube. The concentration of contaminant was similar to that normally encountered in natural gas. It was found that the principal effect was that of change in gas multiplication factor and that compensation may be made by an appropriate change in applied bias voltage.
