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.

Negative-reactivity measurements are frequently made by the rod-drop and source-jerk techniques. Analysis of the data from such experiments by the usual methods requires measurement of the flux-time curve during a transient. Two alternative methods of obtaining negative reactivities are presented here. Neither of these methods requires measurement of a flux transient. Experimental results using these methods are given.
