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.

Anomalous electron heat diffusion across high mode magnetic islands and the nonlocal high mode stochastic magnetic field are researched and compared with earlier low mode research work. The work in this paper uses two typical magnetic islands and a high mode stochastic magnetic field that are aroused by five incompact high mode perturbed magnetic islands. It is found that the mode number of the perturbed magnetic island is another key factor of anomalous electron heat diffusion across the minor radius in tokamak plasmas, besides the ratio of the parallel heat diffusion coefficient to the perpendicular coefficient and the width of diffusive layers.
