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.

An analysis of benchmark experiment on iron for D-T neutrons with JENDL Fusion File and FENDL/E-1.1 suggested that neutron flux above 10 MeV in iron, was underestimated monotonously with depth. Reasons of this underestimation were investigated through various analyses by DORT3.1 with JENDL Fusion Füe, FENDL/E-1.1 and FENDL/E-2.0. The followings for evaluated cross section data on iron around 15 MeV were considered to be possible origins of underestimation of neutron flux above 10 MeV.
1. JENDL Fusion File: Elastic scattering cross sections for forward angles were smaller. Angle-integrated cross section data of (n,2n) and (n,np) reactions were larger.
2. FENDL/E-1.1: Elastic scattering cross sections for forward angles were smaller.
3. FENDL/E-2.0: Angle-integrated cross section data of inelastic scattering and (n,np) reaction were larger.
