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 is described for suppressing secondary electron emission from the negatively biased electrode of a beam direct energy converter by surrounding it with magnetic field lines. Experiments in a positive ion beam converter with a magnetically protected suppressor have shown that the secondary electrons generated by ion bombardment are successfully prevented from leaving the suppressor. It is also found that backscattered ions from the positive electrode occupy a noticeable portion of the loss currents generated in a converter with a copper electrode.
