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 current National Ignition Facility (NIF) ignition target design consists of 18 precisely assembled components. At the center of the target is a capsule fill tube assembly (CFTA), the baseline of which comprises a Be:Cu or CH:Ge multilayer capsule attached to a glass tube that is used for filling the capsule with hydrogen fuel. The current CFTA has 45 specifications that need to be precisely measured, which are grouped into capsule specifications and attachment specifications. Recent modifications to the tools and the procedures for metrology of these specifications have been implemented and are described. These changes resulted from the experience that the CFTA fabrication team had during production in the early hohlraum energetics campaign on NIF; the evolution of these modifications is discussed.
