DOE seeks proposals for AI data centers at Paducah
The Department of Energy’s Office of Environmental Management has issued a request for offer (RFO) seeking proposals from U.S. companies to build and power AI data centers on the DOE’s Paducah Site in Kentucky. Companies are being sought to potentially enter into one or more long-term leasing agreements at the site that would be solely funded by the applicants.

A new approach to modeling fissile solution densities is developed and applied to arbitrary solutions of UO22+, Th4+, Pu4+, H+, and NO3- in water. The model is based on the semiempirical method of Pitzer for describing electrolyte solution thermodynamics. This new density model has been included in the recent release of the SCALE 5 code system as the default for criticality calculations of fissile solutions.
