newrecordconfirmed Sept 2025: DOE's 'conditional' fuel-line pick of Valar, at its own cost; Ward 250's fuel came from a federal lab site

DOE's September 30, 2025 release is the primary record. In the second round of conditional selections for its Fuel Line Pilot Program, DOE selected Oklo, Terrestrial Energy, TRISO-X and Valar Atomics Inc (Hawthorne, CA), Valar's project being to support TRISO fuel fabrication for the Ward 250 deployment and possibly other high-temperature gas reactors. Each company pays all costs of building, running and decommissioning its fuel facility and must arrange its own nuclear feedstock; companies may apply for HALEU through DOE's HALEU Availability Program. DOE had earlier selected Standard Nuclear to build TRISO fuel facilities. World Nuclear News and Mother Jones ('one of four companies', 'last September') report the same selection, and Valar's NOVA release and Series B post list it. Set beside the record: DOE's May 2026 shipping review authorized HALEU TRISO fuel compacts to be shipped to Ward 250 from Los Alamos's criticality center in Nevada, where the NOVA test ran (safe-010); the NOVA release says Valar 'provided' the TRISO fuel, but no record read says who manufactured it; Valar's QA plan describes a 'Valarin' fuel lab at the Utah site (orig-038), for which no DOE authorization is public (safe-031); and the Series B post says Valar will make its own fuel beside its reactors (orig-070).

In plain termsDOE gave Valar conditional permission to set up its own fuel-making line, at its own cost. So far, though, the fuel for Ward 250 was shipped from a federal laboratory site in Nevada, and who made it is not on the public record. Making nuclear fuel is a separate operation with its own hazards, and its approval papers are not public.

verified 2026-09-29: Verify pass 2 (2026-09-29): merged with orig-068 (the same DOE selection; orig-068 held the primary record). DOE release, WNN, Mother Jones and NOVA release re-read; DOE's shipping review added for the fuel's origin. 'Where the NOVA test had used it' softened to 'where the NOVA test ran': the review does not say it is the NOVA fuel. Correction 2026-09-29 (wording review): Mother Jones cited as 'Mother Jones (Kiera Butler), 26 Feb 2026' (narrow quote; headline not repeated).
