The Defense Innovation Unit announced April 10 next steps in the Advanced Nuclear Power for Installations (ANPI) program, launched in 2024 to deploy microreactor nuclear systems for increased power reliability at select military locations.

Eielson Air Force Base in central Alaska has been the preferred location to demonstrate the benefits of microreactors to the U.S. Air Force—and by extension the Defense Department—since 2018. Now, a protracted solicitation process is nearing an end, and the Air Force and the Defense Logistics Agency Energy (DLA Energy) expect to announce a final procurement decision by the end of the summer—or about one year after Oklo Inc. announced that it had been tentatively selected to supply a microreactor under a 30-year power purchase agreement.

William A. Anders

William A. Anders, former chairman of the Nuclear Regulatory Commission and a former member of the American Nuclear Society, died on June 7 at 90 years of age.

In a June 18 statement, the NRC offered condolences on his passing.

“Chairman Anders had an illustrious career far beyond taking one of the most widely seen photos from space,” said NRC chair Christopher Hanson. “He was the only person to serve as commissioner on both the Atomic Energy Commission and NRC, and he served as the new agency’s first chairman, providing institutional continuity while unambiguously committing the agency to serve as an unbiased, independent, and open regulator. We are saddened by his death and extend our condolences to his family.”

Zeno Power Systems was awarded a $30 million contract to build a radioisotope-powered satellite for the U.S. Air Force by 2025. According to a SpaceNews article announcing the development and quoting company cofounder and chief executive officer Tyler Bernstein, the four-year contract is a “strategic funding increase” (STRATFI) agreement that provides $15 million in government funds, matched by $15 million from private investors.

The Department of the Air Force and the Defense Logistics Agency–Energy have released a request for proposals (RFP) for the construction and operation of a microreactor in central Alaska. The Department of Defense wants a 20-year supply of electricity and steam from a 1–5-MW microreactor, but the Eielson Air Force Base (AFB) Microreactor Pilot Program will go beyond a simple power purchase agreement and put the reactor through its paces with tests, at least annually, of the reactor’s walk-away safety and black-start capabilities. The final RFP is available at sam.gov.

In the wake of inspections conducted about a year ago, the Nuclear Regulatory Commission has proposed a civil penalty of $96,000 against the U.S. Air Force for 14 apparent violations of NRC regulations on the use of radioactive materials.

The Department of the Air Force has selected Eielson Air Force Base as the site of a stationary microreactor that “will provide the installation with a clean, reliable, and resilient nuclear energy supply technology for critical national security infrastructure,” the department announced on October 15.
