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 method for determining the prompt neutron decay constant of a fast critical assembly by noise analysis has been developed. It uses a digital computer to do polarity crosscorrelation on the outputs of two scintillation detectors. For the first time, such a measurement has been made in a fast assembly at criticality with no intrinsic limitation on power level. Portions of the technique were adapted for a study of the dynamics of a digital reactor control scheme.
