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 technique for measuring the efficiency of a Ge(Li) spectrometer for gamma-ray sources in “gas bomb” geometries has been developed. The compounds of (CH3)2Se, CH3CH2Br, and CH3I are labeled with 75Se, 82Br, and 131I, respectively. These compounds readily vaporize at reduced pressure. The labeled compounds are flame sealed in small ampoules and the gamma-ray emission rates are measured. The contents of each ampoule are then released into the evacuated gas bomb and the efficiency of the detector for the gas bomb geometry is determined from the emitted gamma rays. The radionuclides of 75Se, 82Br, and 131I emit gamma rays that cover the energy range from 66 to ∼1900 keV without any large gaps. A method is suggested for measuring the efficiency for gas bomb geometries at small detector distances, which minimizes the effect of coincidence summing.
