Army Awards $2.2B for Microreactors

The U.S. Army awarded $2.2 billion in Project Janus funds in August to develop microreactors for domestic bases. Startup Radiant received the largest share for its 1-megawatt Kaleidos system. The Department of Defense previously gave Antares $161 million in June for a space reactor. Officials aim to prove reliability by 2028 before expanding to remote or conflict zones.
