“Small nuclear reactors can provide the power capability necessary for space exploration missions of interest to the Federal government,” the Energy Department wrote in the notice published Friday.

The Energy Department, NASA and Battelle Energy Alliance, the U.S. contractor that manages the Idaho National Laboratory, plan to hold a government-industry webcast technical meeting in August concerning expectations for the program.

The plan has two phases. The first is developing a reactor design. The second is building a test reactor, a second reactor be sent to the moon, and developing a flight system and lander that can transport the reactor to the moon. The goal is to have a reactor, flight system and lander ready to go by the end of 2026.
