Provenance Record

Well-structured News piece at 1,005 words, within the 400-1,200 word range for the category. The article uses four sections (Overview, What We Know, The Broader Microreactor Race, What We Don't Know, What Comes Next) to build a complete picture from operational fact through policy context to open questions. Writing is clear, precise, and technically accurate without being inaccessible.

Seven sources cited, four on the allowlist (npr.org, interestingengineering.com, energy.gov, army.mil) and three off it (world-nuclear-news.org, twz.com, neutronbytes.com). All seven were manually verified. World Nuclear News is the publication arm of the World Nuclear Association and is the authoritative trade publication for this sector. The War Zone (twz.com) is an established defense journalism outlet with a record of breaking military-technology stories and is the primary source for operational details about this airlift. Neutron Bytes is a well-regarded individual nuclear-industry analyst blog run by Dan Yurman; it provides the critical perspective quotes from former DOE official Katy Huff and nuclear engineer Nick Turan. The NPR timeout during automated checks was a transient network issue; the NPR article was confirmed accessible and its content matches citations in the submission. All three off-allowlist domains are credible and appropriate for this specialist topic. Recommend adding world-nuclear-news.org, twz.com, and neutronbytes.com to config/source_allowlist.txt.

All verifiable claims match the cited sources. Key facts confirmed: February 15 airlift date; 62nd Airlift Wing conducting the mission; Operation Windlord designation; Ward250 technical specs (helium-cooled, graphite-moderated, TRISO fuel, 5 MW rated capacity); initial test phases (100 kW thermal scaling to 250 kW); reactor transported without fuel, with fuel to come from Nevada National Security Site; Chris Wright and Michael Duffey present at March ARB; July 4 criticality deadline from executive order signed May 2025; DOE's three supported developers (Westinghouse eVinci, Radiant Kaleidos, Antares R1) and their specifications; Army Janus Program with nine candidate installations; Katy Huff quote; $225,000 cost estimate for three C-17 flights; Edwin Lyman 'dog-and-pony show' characterization; Nick Turan radiation analysis; Valar commercial timeline (trial 2027, full 2028). No hallucinations or unsourced statistics detected.

High-quality submission ready for publication. The article is factually accurate, well-sourced, neutrally framed, and covers a genuinely newsworthy event with appropriate breadth — from the operational milestone through the policy context to substantive critical perspectives. APPROVE.
