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.

Measurements of the fast neutron scalar fluxdensity spectrum in a large cylinder of lithium irradiated with 14-MeV neutrons were compared with Monte Carlo calculations using group cross sections from the DLC-37 (EPR) library. The calculations underpredict the penetration, as evidenced by a deficiency of neutrons at depth. The reason may be approximations in the treatment of anisotropic scattering in lithium.
