Navy picks Radiant's Kaleidos microreactor for a naval weapons station
From the Energy digest for 2026-10-22
What happened: On October 22, 2026 (~7:00 AM ET, World Nuclear News), the US Navy selected Radiant's Kaleidos microreactor for deployment at Naval Weapons Station Crane, Indiana. The item is a selection announcement: no deployment date, contract value, funding figure, or construction schedule appears in it. (This is the Indiana naval station — not the Crane Clean Energy Center restart in Pennsylvania that the restart-wave record follows.)
What's genuinely new: Development — the military lane of the advanced-reactor record already runs through the Army's conditional long-term leases to three companies (announced September 21, 2026, including an Ameresco–Terrestrial Energy IMSR at Aberdeen Proving Ground) and Antares' $161M DoD space-reactor award; this adds the lane's Navy entry, and a siting for a commercial microreactor vendor on a working weapons station. Announcement-grade — "selected," not contracted, licensed, or built.
Watch: Contract and funding details behind the selection; a deployment timeline; the licensing path for a microreactor on a Navy installation; whether named contractors for the three Army leases arrive and how the two services' patterns compare.
