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.

A methodology to adjust resonance parameters is developed and tested on the lowest-energy resonances of 238U, 240Pu, and 242Pu. It is shown that adjusting the basic nuclear parameters is the only consistent way to adjust infinitely dilute cross sections and to reduce the cross-section deconvolution problem. Taking into account the self-shielding effects enables us to treat different kinds of integral experiments (fast and thermal) and to achieve a statistically consistent adjustment. Also, the standard multigroup cross-section adjustment in the epithermal region can be interpreted as an indication of the required correction of an average reaction rate.
