   Key anchors used:
   - The Department of the Army announced that the Janus Program selected five nuclear energy vendors and five initial locations.
   - The Army says it is awarding up to a combined **$2.2 billion** to own, construct and operate nuclear microreactors on military installations, in partnership with DIU.
   - The Army says that with expected private-sector funding, it expects **more than 20 total nuclear microreactors** across Department of War installations.
   - Selected vendor/base pairings: Antares Nuclear — Fort Bragg, North Carolina; BWXT Advanced Technologies — Fort Campbell, Kentucky; General Atomics Electromagnetic Systems — Fort Hood, Texas; Radiant Industries — Fort Benning, Georgia; Westinghouse Government Services — Fort Drum, New York.
   - The Army states the program target is energy resilience for installations and missions, and quotes officials linking Janus to Project Pele and DOE Reactor Pilot Program learning.

   Key anchors used:
   - POWER frames Janus as a five-year effort to build and operate more than 20 commercial nuclear microreactors across military installations.
   - POWER reports a Sept. 30, 2028 deadline for at least one Army-regulated reactor operating at a military installation.
   - POWER adds vendor-level details from company announcements: Radiant up to $750 million for Kaleidos units; BWXT 20-MWe BANR version; General Atomics GA-TES approximately 5 MWe scalable to about 20 MWe; Westinghouse eVinci; Antares R1.
   - POWER notes Army Reactor Regulatory Office oversight for reactors inside installations supplying power to those installations, with an effort to align Army/DOE/NRC processes.

   Key anchors used:
   - ANS reports the Army selected five reactor developers — Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Radiant Industries and Westinghouse Government Services — each paired with a different military installation.
   - ANS places Janus in the context of a busy month for federal nuclear-industry partnerships, including Nuclear Lifecycle Innovation Campuses and Nuclear Energy Launch Pad.

## Editorial cautions
- Do not describe the Janus announcement as a completed reactor deployment, permanent base power solution, NRC commercial licence, or proof that microreactors are now routine.
- Keep the procurement/authorization posture precise: the Army says vendors will own, construct and operate microreactors; POWER describes milestone-based OTA agreements and Army safety authorization, but public details remain vendor- and site-specific.
- Military demand can be a commercialization bridge, but it can also hide difficult questions: lifecycle cost, security perimeter, emergency planning, fuel supply, waste handling, utility coordination, community consent and transferability to civilian mines/data centers.
- Not investment advice: some selected firms or their partners are public or connected to public-company supply chains, but this source card is evidence-trail research, not a buy/sell/hold recommendation.
