The Department of the Air Force (DAF) and the Defense Innovation Unit within the Department of Defense have selected Buckley Space Force Base in Colorado and Malmstrom Air Force Base in Montana to potentially site microreactors.

Wednesday’s announcement moves forward the plans of the Advanced Nuclear Power for Installations (ANPI) program, which was launched in 2024 with the objective of deploying “advanced, contractor-owned and operated” microreactors from commercial reactor companies on bases.

A “resurgence of interest” in nuclear propulsion for space missions is described in a new article authored by science writer Jon Kelvey for the American Institute of Aeronautics and Astronautics’ (AIAA’s) Aerospace America website. The focus of Kelvey’s article is nuclear thermal propulsion (NTP), which, according to the Department of Energy, “could significantly reduce travel times and carry greater payloads than today’s top chemical rockets­—giving humans a great chance of exploring deep space.”

Brouillette

In remarks addressed to a meeting of the National Space Council on May 19, Energy Secretary Dan Brouillette said that the development and deployment of small modular reactors could provide sustainable power sources for space applications.
