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.

Predictive simulations of target plasmas for the National Compact Stellarator Experiment (NCSX) were performed as part of the design effort. The resistive stability of these simulated target plasmas was studied using a quasi-cylindrical ' stability code, as has been done with some success for W7-AS plasmas. The plasmas were found to be classically unstable to an m = 2, n = 1 tearing mode during the start-up, but the 2/1 saturated island size in the target equilibrium was small, <2%. Inclusion of neoclassical effects resulted in negligible island sizes throughout.
