# Source note — DOE HALEU for NASA and Radiant: Fuel Supply Is the Gate

## Bottom line

Publishable item found. The substantive new development is DOE's third round of conditional HALEU commitments to NASA and Radiant Industries, paired with a fresh Federal Register/NRC notice for Radiant's special nuclear material licence application. This is distinct from the July 25 DOE microreactor-criticality source card because the main issue here is fuel-chain availability and material possession/licensing, not criticality testing.

1. DOE Office of Nuclear Energy, **“Energy Department to Distribute Third Round of HALEU to NASA and Radiant”** — https://www.energy.gov/ne/articles/energy-department-distribute-third-round-haleu-nasa-and-radiant  
   - Published July 23, 2026.
   - DOE says it made conditional commitments to provide high-assay low-enriched uranium (HALEU) to NASA and Radiant Industries, Inc. to meet near-term fuel needs.
   - DOE says the third allocation round supports NASA's SR-1 Freedom mission to Mars and Radiant's deployment of a microreactor to the Air Force's preferred location of Buckley Space Force Base in Colorado.
   - DOE says HALEU is not currently available from domestic suppliers and many advanced reactors need the material for smaller designs, longer operating cycles and increased efficiencies.
   - DOE says NASA is a first-time recipient, Radiant is receiving a second selection, and DOE will initiate contracting with NASA and Radiant to allocate the material.

   - Publication date: July 27, 2026.
   - API/metadata confirms NRC received Radiant's licence application by letters dated February 25, March 15 and April 17, 2026.
   - Application concerns possession of special nuclear material at Radiant's R-50 microreactor facility, to be located in Oak Ridge, Tennessee.
   - Fuel description in abstract: coated uranium particles enriched to less than 20 weight percent U-235, to be loaded into assemblies intended for commercial microreactors.
   - Dockets: `Docket No. 70-7045`, `NRC-2026-3598`.
   - Dates: hearing/petition deadline September 25, 2026; SUNSI access request deadline August 6, 2026.

1. ANS / Nuclear Newswire, **“NASA and Radiant selected to receive HALEU”** — https://www.ans.org/news/2026-07-27/article-8246/nasa-and-radiant-selected-to-receive-haleu/  
   - Published July 27, 2026.
   - Corroborates DOE's conditional HALEU commitment to NASA and Radiant.
   - Adds context that the announcement follows a Centrus Energy contract to finalize terms of a $900 million DOE task order to expand HALEU production capacity at the American Centrifuge Plant in Piketon, Ohio.
   - Notes the Federal Register hearing/intervention date for Radiant's special nuclear material licence application.

2. Business Wire / Radiant company release — **“DOE Selects Radiant for Second HALEU Allocation…”** — https://www.businesswire.com/news/home/20260723497546/en/DOE-Selects-Radiant-for-Second-HALEU-Allocation-to-Support-First-Commercial-Microreactor-at-a-U.S.-Military-Installation  
   - Resolved through Google News RSS but timed out during terminal fetch. Treated as a company-release lead only, not a factual anchor.

## Leads checked and skipped

- **Tennessee Selected as Finalist for U.S. Department of Energy Nuclear Lifecycle Innovation Campus** (TN.gov, July 28 RSS lead). Google News surfaced it, but the direct TN.gov guessed URL returned 404 and the lead was less tightly source-verified during this run. Keep for a future Energy watch if an official page is reachable.
- **Framatome Secures NRC Approval to Enrich Uranium to 10% at Richland** appeared in lower-confidence aggregator results. No direct NRC/Framatome official page was verified during this run, so it was not selected.
- Stock-list and uranium-pick articles were skipped to avoid market-promotion framing.

## Evidence labels / cautions

- **Verified official development:** DOE conditional HALEU commitments to NASA and Radiant.
- **Verified regulatory-process signal:** Federal Register/NRC notice confirming Radiant's special nuclear material licence application and deadlines.
- **Not yet proven:** actual fuel delivery, completed contract terms, licence approval, reactor operation, power sale, commercial deployment, or NASA mission success.
- **Fuel-chain caution:** HALEU availability, enrichment, fabrication, transport, storage, safeguards and security remain separate gates.
- **Market caution:** uranium/enrichment/fabrication implications are strategic infrastructure-watch items, not investment advice.
