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 neutron spectrometry system is proposed to provide information about the ion plasma temperature profiles in the International Thermonuclear Experimental Reactor (ITER) cross section. The system consists of two fanlike arrays of spectrometers and collimators positioned horizontally (20 channels) and vertically to the machine (10 channels). The devices are intended for use in both the deuterium-deuterium (D-D) (physical) and deuterium-tritium (technology) phases of ITER operation. For the D-D phase of operation, a system using NE-213 liquid scintillators and a 3He ionization chamber is proposed. A new high-performance neutron spectrometer based on recoil-proton energy measurements by means of a semiconductor detector and neutron spectrum unfolding is proposed for the technology phase.
