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 chaotic phenomena of the low frequency magnetic fluctuations in the HANBIT device have been studied and measured by two magnetic probe arrays in the central cell. The HANA (HANBIT Nonlinear Analysis) code has been developed and used to analyze the magnetic fluctuations to determine whether or not it is chaotic. The autocorrelation function of the magnetic fluctuations is obtained at two different positions in the HANBIT device and was also used to determine chaotic transition. The influence of the magnetic field strength on the magnetic fluctuations has also been studied. When the magnetic field strength is over 0.229 T~ 0.233 T, wave bifurcation is observed and the Primary Lyapunov Exponent (PLE) value is increased. Hence, there is chaotic transition at a specific magnetic field strength in the HANBIT device.
