According to a press release from Santa Clara-based Oklo Inc., the USAF issued a Notice of Intent to Award a contract for micro-reactors to supply power and heat to Eielson Air Force Base. 

"This project represents a significant stride towards ensuring a clean and resilient energy supply for critical national security infrastructure," the company said

The timeline for the installation wasn't specified, and Oklo's design still awaits the green light from the Nuclear Regulatory Commission (NRC):

This selection initiates the acquisition process to potentially award a contract to Oklo. Oklo would obtain a license for its power plant from the Nuclear Regulatory Commission, construct the power plant, and operate it to deliver both electricity and steam to the Eielson Air Force Base under a long-term power purchase agreement executed by the Defense Logistics Agency Energy. --Oklo
