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.

For the International Thermonuclear Experimental Reactor (ITER), the European Union intends to introduce a test blanket module using liquid lithium lead. In the present study, a preliminary experiment was conducted using a LiAl/Pb assembly, which has a neutronics performance similar to lithium lead. The neutron spectrum at the inside of the assembly was measured with an NE-213 detector. We found that the spectra calculated with MCNP5 and JENDL-3.3 underestimate the 14-MeV peak by no less than 30%, while ENDF/B-VII.0 and JEFF-3.1 gave good agreement. The neutron nuclear data of lead stored in JENDL-3.3 may have some problems.
