DOE awards $2.7B for HALEU and LEU enrichment
Yesterday, the Department of Energy announced that three enrichment services companies have been awarded task orders worth $900 million each. Those task orders were given to American Centrifuge Operating (a Centrus Energy subsidiary) and General Matter, both of which will develop domestic HALEU enrichment capacity, along with Orano Federal Services, which will build domestic LEU enrichment capacity.
The DOE also announced that it has awarded Global Laser Enrichment an additional $28 million to continue advancing next generation enrichment technology.

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.
